회전 기물면을 이용한 초음파 집속기에 관한 연구

김주홍,전병실 대한전자공학회 1974 전자공학회지 Vol.11 No.1

본 연구는 강력한 초음파 음계를 형성시키는 것을 목적으로한 반사형 초음파 집속기에 관한 것이다. 이 집속기는 초음파반사의 임계각이 일어난 점을 경계로 하는 전반사가 일어나는 반사면만을 이용한 회전 기물체로 구성하였다. 그리고 초음파를 발생한 변환기의 형태에 따라 평판형 변환기에 적용되는 내측면 반사체와 원간형 변환기에 운용된 외측면 반사체의 2종으로 구분하여 집속기를 설계제작하고 측정하였다. 이 반사형 집속기는 plastics lens에 의한 투과형 집속기에 비하여 여러가지 장점을 갖이고 있다. 즉 재질에 유리나 금속을 사용하므로 높은 온도의 매체중은 물론 강력한 음계내에서 적용도가 크고 또 전반사를 이용하므로 집속효율이 커서 강력한 초음파 음계를 필요로 한 공업용 초음파 집속기로 이용될 것으로 사료된다. This paper discribes the reflector type ultrasonic concentrator which makes hghintencity of ultrasonic field. This was made by rotating parabolic surface which only using total reflection aria, that makes boundary by the critical angle of reflection of sound. I made two binds of concentrator acording to the type of ultrasonic transduser: one is internal surface reflector type concentrator, which is available for disc type transducer, and the other is external surface reflector type concentrator which is available cylinderical transduser. In the mony aspects the reflector tripe concentrator is supel'ier to the reflection type concentrator as plastics lens; It is more durable in high temperature and high intencity ultrasonicfield then refrector type concentrator because of it is made by glass or metal, and it has higher. efficiency because of it wasts made by only total reflection aria that is without absoption lose. I think this is useful ultrasonic concentrator in mony industrial field, in which high intencitr of ultrasonic energy was used.

Signal fires were an important military communications facility during the Three-Nations Dynasty and Joseon Dynasty. The flames and smoke coming from the fire were used to relay urgent messages to people at far distances. These signal fire systems were developed in China during the Three-nations period and Korea imported the technology and used it. However there is no concrete evidence or remnants of the signal fire system, so the true nature of them is yet to be uncovered. The signal fire system became more developed during King Euijong′s reign in 1149, at Jo Jin Yak(曺晋若)′s memorial service. However during the reign of king Injong in 1123, diplomats from the Sung(宋) Dynasty used the signal fires while coming and going from the capital city of Gaeseong. From this, it can be construed that during times of peace these signal fires were also used to guide visiting foreign diplomats. It can be concluded that at the tine, Goryeo′s signal fire system was not yet complete; however the signal fire system was installed in the capital of Gaeseong and in a few main coastal fortresses. When marked on a map, it is clear that there were many more signal fire systems around the capital of Gaeseong and coastal cities such as Incheon, Ganghwa, Kimpo and Paju. This means that during times of foreign invasions, the signal fires were used to let people know of the invasion. Much importance was attached to the construction of the coastal signal fires on sea routes and they were built to be intricately linked to nearby mountain fortresses. The signal fire system of Joseon was directly transferred from the Goryeo period. Since the beginning, the number of fire signals was the foundation for the Joseon signal fire system. However, during early Joseon the usage of the signal fires was different than that of the Goryeo period. In order to prepare for the invasion by the Jurchen(女眞) tribe, King Sejong in 1433, officially constructed many signal fires after he developed four counties upstream of the Amnok River, and 6 military bases in Naman, downstream of the Duman River. The purpose of construction, the construction itself, and the formation process were all different compared to that of the Goryeo Dynasty. Presently there are 54 signal fire systems across the Gyeonggi province that were constructed during that era and they all embody the special characteristics of the Gyeonggi province. They also differ according to the route, altitude, location, and architectural style. In order to reach the five major signal fires that were set up during the Sejong era in early Joseon one had to pass through the signals of the present-day Gyeonggi province, and this province had the largest number of signal fires after Gyeongsang province. Also, the coastal and inland parts of Chungcheong, Gyeongsang, and Jeolla had certain specified routes of signal fires while Gyeonggi province had routes connecting all five major signal fires, with each characterized by the color of its area. This paper have kept the following points in mind while studying the signal fire system of the Gyeonggi province during the Joseon period. In the preface, there is a general outline of the signal fire system starting from the Three nations period up to the Joseon period, and it is followed by an introduction of the present situation of all signal fire systems studies conducted up until now. This presents a direction for further investigation. In the second chapter there is a look at the establishment of the signal fire system. After a brief mention of the signal fire system of the Joseon period-which had its foundation in five main torchlight systems, the number of signal fire systems across all provinces and routes are organized Additionally, after analyzing each piece of document, the characteristics and establishment intentions are outlined according to the number of signal fire systems that has been measured. The reason for doing this is because the result of num

This study aims to investigate Taean, the place having rapid tidal current against cargo ships and the roles of Anheung Camp (Anheungjin) as the salvation place backside in the river city through poems and essays shown in the literature collections of scholars in Joseon Dynasty. In addition, this study also found out how the roles of Anheungjin as a port of call for transport ships and Sogeun Camp (Sogeunjin) which was established to pray for safe sailing of the transport ships were carried out through the operation of watchtowers. Chapter I reviewed a number of the sinking accidents of transport ships in Anheungryang which was called as Nanhaengryang (meaning the place of rapid tidal current), damages of human lives, and plunder of Japanese pirates in poems and essays shown in the literature collections of scholars, which are introduced as a basic material to restore the tough life of Taean residents who had to scoop out the grains for tributes from the wrecked ships and take the burden to wrap up the situations. Chapter II investigated the attempt to do excavation work for the Gulpo canal in order to change Nanhaengryang to Anheungryang by era. Such attempts had been done since the time of King Injong in the Goryeo Kingdom. There were persistent attempts for the excavation work according to great interests shown by kings and subjects even after the foundation of the Joseon Dynasty but they failed after all. This study showed the probabilities of the excavation works in Gulpo through the poems of various scholars by clause. Chapter III reviewed poems and essays shown in the collection of scholars in the Joseon Dynasty by clause and by theme in order to understand the circumstances of the Anheung region. Through Chinese poems, Clause 1 deals with the attempts for the excavation works in Gulpo in order to solve the difficulties of passing through Namhaengryang, the hardship resulted from the failure in excavation works, and the poems related to civil hardship due to the sinking accidents of transport ships. Clause 2 shows poems and essays of various scholars related to Anheungjin which was encamped as a salvation place in Ganghwado after the Qing invasion of Joseon. Clause 3 introduces poems, essays, and petition letters to the King related to Anheungjin, through which we can suspect the recognitions of scholars at that time on the Taean region. Lastly, it shows literature records and the current status of the eight watchtowers supervised by Anheungjin and Sogeunjin. Among them, it was passed down orally that the watchtower in Shinjinri guided the sea routes for envoys from Song Dynasty as well as serving for ritual service that prayed for a safe voyage. As a result of this study on poems of scholars, it was confirmed that being succeeded from the Goryeo Kingdom, Taean functioned as a place for scouts to defend against Japanese pirates in the Joseon Dynasty. This study also identified the guidance of transport ships and the fact that the guard soldiers (supervising officers) resided all the time to detect drift or emergence of any foreign ships and they performed their duty faithfully. This study also found out new facts through the realistic expression of the people at that time. Defending Ganghwado by Anheungjin, escorting transport ships by Sogeunjin, and establishing and operating watchtower to watch out the sea are those newly introduced facts in this study for the first time. In relation to further survey and research of the navy camp to do, studies of the watchtowers should be done as well. 본 연구는 조선시대 文人들의 文集에 나타난 詩와 散文을 통해 漕運船 難行梁으로서의 泰安과 江都의 배후 구원처로서의 安興鎭 역할을 살펴보는 데 목적이 있다. 이외 조운선의 기항지인 안흥진과 이들 조운선의 무사 운항을 위한 所斤鎭의 역할이 候望所의 운용을 통해 어떻게 이루어졌는지를 고찰하였다. 본 연구 관련 제Ⅰ장에서는 文人들의 文集에 나타난 詩와 散文이 難行梁이라 일컬었던 安興梁에서 조운선의 다수 침몰과 인명 피해외 왜구의 노략을 검토하였다. 그리고, 당시의 수운체계와 이들 해중에 침몰한 세곡을 건져내고 뒤처리와 부담을 떠안아야 했던 태안 지역민들의 고단했던 삶을 복원하는 기초자료임을 소개하였다. 제Ⅱ장에서는 난행량을 안흥량으로 바꾸기 위한 堀浦 掘鑿 시도를 시대별로 살펴보았다. 이러한 시도는 고려 인종대부터 있었다. 조선 건국 후에도 역대 왕과 대신들의 지대한 관심 속에 지속적인 굴착 시도가 있었으나 결국 실패하였다. 이어 각 항별로 여러 문인들의 詩를 통해 굴포 굴착의 개연성을 소개하였다. 제Ⅲ장에서는 과거 안흥 지역의 상황을 이해할 수 있도록, 조선 시대 文人들의 文集에 나타난 詩와 散文을 각 항별 주제별로 살펴 보았다. 1항은 한시를 통해 난행량 통과의 어려움을 해결하기 위한 굴포 굴착 시도와 실패가 가져온 어려움, 조운선 침몰로 인한 민폐 발생 관련 시. 2항은 丙子胡亂 후, 강도의 배후 구원처로서 설진된 安興鎭 관련 여러 문인의 시와 산문. 3항은 안흥진과 관련된 글을 통해 당시 문인들의 태안 지역 인식을 추정해볼 수 있는 시와 산문외 상소. 끝으로, 안흥진과 소근진에서 소관하였던 8개소의 望臺所에 대한 문헌 기록과 현황을 소개하였다. 이중 신진리 후망소는 고려 시대에 宋나라 사신들의 항로를 안내하고, 동시에 무사 항로를 기원하는 祭祀의 장소였다고 口傳으로 전해진 곳이다. 본 연구에서 문인들의 詩를 통해 살펴본 결과, 조선 시대에는 고려의 기능을 이어 倭寇防禦를 위한 斥候所였음을 새로 확인하였다. 이외 漕運船의 안내, 그리고 조선 후기에는 異樣船·荒唐船의 표류와 출현을 후망하기 위해 항시 望軍(監官)이 상주하며 그 역할을 충실히 수행했음을 밝혔다. 이 연구에서 당대인들의 현장감 있는 표현을 통해 새로운 사실을 확인하였다. 본 연구를 통해 향후 안흥진의 강도 구원과 소근진의 조운선 호송 역할에서 해상의 후망을 위한 후망소의 설치 운용은 처음으로 소개하는 것이다. 향후 진행예정인 수군진 조사·연구와 관련하여 이들 배후 후망소에 대한 조사·연구도 같이 이루어져야 할 것이다.
