Title: Optical writing device
Inventor: ASAI TAKAHIRO
IPC: B41J2/44
Filed: 1981-05-19
Abstract: PURPOSE:To make an optical path length shorter and a deflector lighter in weight and to make the inexpensive provision of a small-sized optical writing device possible by providing the deflector which deflects parallel luminous fluxes to a photoreceptor side and condensing these respectively onto the photoreceptor surface. CONSTITUTION:An optical writing device is provided with a deflector 20, and is so arranged that parallel luminous fluxes 11, 12 located above and below both enter one side of the deflector 20. A plane mirror 21 and a convex lens 22 are provided in the deflector 20 so that the mirror 21 deflects the fluxes 11 and 12 so as to make them incident vertically to a photoreceptor 10 and that the lens 22 focuses the fluxes 11, 12 deflected by the mirror 21 onto the photoreceptor 10. Since the deflector 20 moves along the fluxes 11, 12, the optical path length between the deflector and the photosensitive drum is constant, and can be made shorter; therefore, the device is made lighter in weight and lower in cost.

Title: Methane generator comprising multistage fermentation part
Inventor: TSUBOTA JIYUNJIROU
IPC: C02F11/04
Filed: 1980-06-05
Abstract: PURPOSE: To provide an apparatus for facilitating complete speedy methane fermentation without  necessity of any special heat source, by gradually carrying a fermenting material from a prefermenting zone in a heat-insulated vessel through an isolated feed line to a methane fermenting  zone.  
     CONSTITUTION: Water is poured into a methane fermenting zone 3 up to a chained line level by  a gauge 13, and inoculated if possible. The lower end of a feed line 10 is consequently water- sealed. When a proper amount of a fermenting material is charged and reserved in a prefermenting zone through a charge opening 4, aerobic fermentation is started on a vibrating feeder 15 at  the uppermost stage, so that heat is generated and the fermentation is promoted. The fermenting  bacteria are flaked, liquidized and gradually carried downwards. Consequently, prefermented materials having different fermentation rates are accumulated as shown in the drawing after 10W15  days. Within this period, water in the zone 3 changes to a state most suitable for methane fermentation, and generated gases push the liquid upwards in the line 10. A taking-out opening 11 is  repeatedly opened to discharge residual gases and to leave methane gas alone. As a result, the apparatus reaches a steady condition. Thereafter, methane gas is obtained by gradually feeding the  prefermented material into the fermentation liquid.
