江戸時代は色々な階層の人々が全国の街道を往来しながら旅をする時期であったが、初期には社会的なインフラが整備されない状況のために、庶民たちの私的な旅がは自由に行なわれなかった。中期に入って平和が定着され、農民や町人たちの経済力と生活水準の向上に伴って多様な庶民の文化が発達したので、これを基にして旅は次第に大衆化していった。そうではあるが封建制度下での江戸時代は原則的に庶民たちの旅が禁止されていて、特に農民と女性は厳しい統制が行なわれていた。しかし宗敎的な目的の参拜や温泉での湯治は例外に当たったので、庶民たちはこれを口実に旅をする場合が多かった。そして江戸後期になると、参拝を立前にして本音は物見遊覧と日常からの解放感を楽しむ庶民たちの旅が爆発的に増加していった。 本論文は、江戸時代の色々な旅の様子の中でも特に信仰に関する庶民たちの集団的な旅を中心にして、その歴史的な意味と社会に及ぼした影響について考えてみることを目的とする。今日我々が一般的に知っている「観光」または「旅行」としての旅が許されない時代的な状況の中で、お伊勢参りのような大規模の集団的な旅が、権力と制度から抑圧された庶民たちの自我を取り戻すための意識の発露であったということを考察しようとする。

This paper is the study of forklift on the development of proportional control valve system. Small forklift is the transmission by the pilot pressure. So a lot of time and money is needed to adjust the sensitivity of transmission. Proportional control valve to easily adjust the clutch pressure. Proportional control valve to change the shape of the input waveform by adjusting the clutch pressure. Input waveform is changed by using the program. In this paper, we simulate the proportional control valve and the clutch pack. Proportional control valve to simulate the performance of Forklift and find ways to reduce shift shock.

Most of the soundproof tunnels generate significant discharge noise through their inlets and outlets so that the length of the tunnel has been extended frequently than required to minimize the effect on such discharge noise. Thus, in this paper, we investigate reduction capability of discharge noise from the sound proof tunnel installed with lateral sound-absorbing panels on the partitioned truss members in the longitudinal direction of the tunnel. In conclusion, noise field analysis results shows that the sound proof tunnels with lateral sound-absorbing panels have an effect on discharge noise abatement and thereby tunnel``s length reduction.

Recently the design of vane pumps are compact is consisting much. In order to control excess inflow in lubrication a relief valve has attached with constant capacity vane pump, while out flow being proportional to engine rpm varies accordingly. But during high engine speed lubricant flows in excess and due to high engine torque, fuel efficiency is worsened. Therefore, the design considerations are to develop, analysis, layout, method of exam and construction method of a variable capacity type vane pump to obtain high effectiveness, high fuel efficiency as well as to reduce noise. It is last target to shorten design period and apply to engine as that developed by a vane pump. This paper describes the development procedure of a cam ring rotation type variable discharge vane pump for engine lubrication, develop automatism program, prototype production and verify performance.

Recently Vehicle"s black box for analysis of the accident, mainly the camera images are stored. But on issues such as sudden unintended acceleration type are insufficient for analysis. Because of the information collected by various sensors on the basis of analysis will be available is a vehicle accident. In this paper from inside the vehicle to get the basic information to monitor and collect data for the analysis of vehicle accidents caused by internal defects can be to build a system. This paper is using the TCP/IP communication measured of the vehicle. And remote communication using the stored vehicles were able to store data on a sever.

The transmission control method of small forklift is classified into pilot control method and direct control method. In pilot control method, the hydraulic circuit which consists a lot of components is very complex so the production process is too costly and time consuming. The direct control method contains fewer components that can be configured to simple hydraulic circuit. It has more advantages because the shift sensitivity of transmission is changed easily via the input profile. In this paper, the controller design and the input profile for system are studied to apply to the direct control method. The input profile consists of Fill section, Hold section and Ramp section. The characteristic of each section is obtained through experiment. As the result, the shift sensitivity and starting performance are effected by Fill section and Hold section.
