Title: Thin film solar cell
Inventor: ICHIKAWA YUKIMI
IPC: H01L31/0224
Filed: 1987-09-02
Abstract: PURPOSE:To enable reduction in loss of power in a transparent electrode layer even with unit cell width made wider by connecting the unit cells at part which extends in a short side direction thereof, being equally divided in a long side direction thereof, besides gaps between the unit cells. CONSTITUTION:Extension parts 52-54 of second electrode layers are brought into contact, at gaps between adjacent unit cells, with transparent strip-shaped first electrode layers 21-23 formed on a substrate 1, together with branch- shaped collectors 62-64 located perpendicularlly to said extension parts. For example, a metal electrode 62 is brought into direct contact at this part with a transparent electrode, serving as the branched collector, which is integrally united with a metal electrode of an adjacent unit cell. A solar cell having such a structure can reduce power loss in the transparent electrode if a distance d between adjacent ones of the branched collectors 62-64 is selected in proper even with the unit cell being made wider in its width w.

Title: Deflecting yoke
Inventor: ITO KEIJI
IPC: H01J29/76
Filed: 1986-09-17
Abstract: PURPOSE:To prevent the distortion of image screen even though a temperature variation occurs, by composing a raster distortion correcting magnet unit with the first and the second magnets of a rotary adjusting type superposing in the reverse polarities each other. CONSTITUTION:The first and the second magnets 5 and 6 are superposed to be in the reverse polarities each other, and held rotatable by a pair of magnet holders 3 and 3. By the rotation adjustment of the first magnet 5, the raster shown in the one point chain line is corrected to push in as the dotted line, and after that, the first magnet 5 is fixed to the magnet holders 3 and 3. Then, the second magnet 6 is installed to the magnet holders 3 to be in the reverse polarity. And by the rotation adjustment of the second magnet 6, the raster in the dotted line is corrected to the raster in the solid line by pulling out 5 parts, about a half of the pushing-in amount by the first magnet 5 whose amount is 10 parts. Therefore, the raster does not move even if a temperature variation occurs, and the adequate position initially adjusted can be maintained.

Title: Production of hydrogen gas
Inventor: YAMAKITA HIROMI
IPC: C01B3/04
Filed: 1986-09-18
Abstract: PURPOSE:To produce hydrogen gas which is a highly valuable fuel, at a low cost, using a raw material which heretofore has been difficult to use as a fuel, by dispersing fine particles of zinc sulfide in a mixture of an amino resin and water and irradiating the dispersion with light. CONSTITUTION:Powder or viscous liquid of an amino resin (e.g. urea resin, melamine resin, etc.) is mixed with water. Fine particles of zinc sulfide are dispersed in the mixture and the dispersion is charged into a transparent reaction vessel. The reaction vessel is made of a material inert to amino acid and water and transparent to light, e.g. quartz, etc. The dispersion is irradiated with light preferably after removing dissolved air by passing an inert gas such as Ar through the reaction liquid. The hydrogen gas produced by the light irradiation is collected to the upper part of the reaction vessel and is easily separated. The amino resin used as a raw material is discharged as an industrial waste or domestic waste in large quantity and is difficult to be used as a fuel as it is. The present process enables the production of hydrogen gas as a high- quality fuel from such a waste effectively utilizing solar energy.
