Characteristics of a Magnetically Levitated Vehicle using a Small Number of Dry Cell Batteries
Kakinoki, Toshio,Yamaguchi, Hitoshi,Mukai, Eiichi Journal of International Conference on Electrical 2014 Journal of international Conference on Electrical Vol.3 No.2
This paper describes magnetically levitated vehicle with hybrid magnets, which have been studied by the authors in place of streetcars or conveyance system. An experimental vehicle of 20kg was magnetically levitated by using a small number of dry-cell batteries, which consisted of 10 Ni-MH cells of 1900mAh in series. The magnets were activated sequentially, because the internal resistance of the batteries suppressed the maximum current. The vehicle was kept levitating for about 2 hours and was stable against disturbance due to instantaneous external force. In this paper, dynamic characteristics of the magnetically levitated vehicle using a small number of dry cell batteries are presented.
A Turnout without Movable Parts for Magnetically Levitated Vehicles with Hybrid Magnets
Kakinoki, Toshio,Yamaguchi, Hitoshi,Yoshinaga, Naoya,Mukai, Eiichi,Nishi, Hiroyuki Journal of International Conference on Electrical 2014 Journal of international Conference on Electrical Vol.3 No.3
This paper describes a turnout without movable parts for magnetically levitated vehicles with hybrid magnets, which have been studied by the authors in place of streetcars. Their low construction cost and low maintenance is key to their practical use. Magnetic levitation systems using forces of attraction can generate guidance force automatically, but the damping force against lateral motion is negligible. However, the lateral damping characteristic was improved by using divided iron type magnets and rails. Using this turnout without movable parts will facilitate smooth direction switching.

Novel macrocyclic ligands modified with pendant arms, N, N', N'', N''', N'''', N'''''-hexakis(2-aminoethyl)-1, 4, 7, 10, 13, 16-hexaazacyclootadecane [$L_3$, Fig.1] and 1, 4, 7-tris(3-(o-hydroxyphenyl)propyl)-1, 4, 7-triazacyclononane [$L_4$, Fig.1] have been synthesized, and the protonation of $L_3$ and $L_4$ and stability constants of $L_3$ with bivalent transition metal ions and rare earth metal ions were determined by a potentiometry. The obtained results show that the complex formation of $L_3$ depends on the metal ligand ratios, and the stability of the metal complexes does not depend on the sizes of the metal ions, but on the nature of the metal ions. The structures of the rare earth complexes for $L_4$ were characterized by an X-ray absorption spectrometry(XAFS).
자기연마법에 의한 파인세라믹 Bar의 가공특성에 관한 연구
문상돈,Takeo Shinmura,Hitomi Yamaguchi,Toshio Aizawa,조철용 한국공작기계학회 2006 한국공작기계학회 추계학술대회논문집 Vol.2006 No.-
In this paper, the possibility of high precision machining was confirmed by using magnetic abrasive finishing process with rotating fine ceramic bar in high speed. Also, in order to improve the surface roughness, it was used the vibration of the magnetic pole and the mixed grain which is mixed with diamond paste for ultra precision processing and electrolytic iron powder. As a result, we knew that there is closely connected with diamond grain size, change of quantity and vibration of the magnetic pole to surface roughness of ceramic bar.

We examined the generation of harmonic voltage by a synchronous machine adding d-axis and q-axis harmonic field windings in order to reduce the harmonics in a power line. We derived the expressions of the armature voltage in the case of supplying the currents with the frequency nf to the d-axis and q-axis harmonic field windings. We constructed the synchronous machine adding the harmonic windings. In this paper, the expressions and the experimental results on the generation of harmonic voltages by the synchronous machine are presented.

We investigated the harmonic voltages generated by a synchronous machine adding d-axis and q-axis harmonic field windings to reduce the harmonics in a power line. First, electronic circuits such as a frequency multiplier, band-pass filter, and phase shifter were newly designed and made to carry out the experiment. Next, an experimental circuit, for which an AC voltage of frequency 6f synchronized to the power line voltage of frequency f could be obtained, was constructed to examine the generation of harmonic voltage in more detail. Finally, an experiment involving the generation of harmonic voltage was performed using an experimental synchronous generator with harmonic windings in the d-axis and q-axis. In this paper, the power spectrum and the waveforms of the harmonic voltages in the armature winding are presented. Moreover, the values calculated from theoretical expressions of harmonic voltages in armature winding are compared with the values obtained by the experiment.
