Title: Manufacture of gas diffusion electrode for cell
Inventor: KAWAGUCHI MASAO
IPC: H01M12/06
Filed: 1988-03-31
Abstract: PURPOSE:To improve the discharge characteristic under the wide-range environment by coating polyvinyl alcohol(PVA) on a positive electrode catalyst layer, drying it, allowing the bridging agent of PVA to exist, then pressing a separator. CONSTITUTION:Polyvinyl alcohol 6 is coated on the surface of the positive electrode catalyst layer 5 of a gas diffusion electrode integrated with the positive electrode catalyst layer 5 and a separator 8 via polyvinyl alcohol, it is dried, the bridging agent 7 of the polyvinyl alcohol is allowed to exist, the separator 8 is stuck to the surface of the catalyst layer. The constitution of the catalyst layer 5/PVA layer 6/bridged PVA layer 7/separator 8 can be formed, thus the adhesive strength between the catalyst layer 5 and the separator 8 becomes stronger as a whole than the conventional constitution of the catalyst layer/PVA layer/separator or catalyst layer/bridged PVA layer/ separator. The occurrence rate of the increase of the internal resistance before or during a discharge caused by the peeling between the catalyst layer 5 and the separator 8 can be suppressed.

Title: Production of photoreceptor drum
Inventor: SAITO SAKAE
IPC: G03G5/05
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To make it possible to remove a photosensitive agent from the inside surface at the bottom end of a photoreceptor drum without contaminating the outside surface of the photoreceptor drum with a treating liquid. SOLUTION: This process for production consists in immersing the one end of the photoreceptor drum 1 formed by applying the photosensitive agent on a tube stock by immersing method into a vessel 4 of the treating liquid 3 consisting of a solvent dissolving the photosensitive agent and concentrically inserting, in this state, a rotating body 5 flocked with brushes on its peripheral surface into the photoreceptor drum 1 and rotating, thereby removing the photosensitive agent on the inside surface at the bottom end of the photoreceptor drum 1 with the brushes 7. The peripheral surface of the rotating body 5 of this case is provided with regions 8B not flocked with the brushes laterally parting the flocking area 8A of the brushes 7.  As a result, the solvent vapor evaporated at the bottom end in the photoreceptor drum 1 is made to escape to the upper part by the regions 8B not flocked with the brushes on the peripheral surface of the rotating body and, therefore, the increase in the internal pressure at the bottom end of the photoreceptor drum by filling of the solvent vapor may be averted. Consequently, the contaminating of the outside surface of the photoreceptor drum 1 with the treating liquid 3 in consequence of the air bubbles generated by the internal pressure increase at the bottom end of the photoreceptor drum 1 may be prevented.

Abstract: PURPOSE:To facilitate the assembling and disassembling of an optical system driving wire locking mechanism part, by holding said driving wire between a locking plate and a fixed bracket in the copying mode and then releasing the above-mentioned locking state when the optical system is moved to the variable magnification position. CONSTITUTION:In the copying mode, no electric conduction is given to a solenoid 24, and the counterclockwise turn is given to a locking plate 25 centering on the parts of the cut engagement ends 25b and 25c and by the expanding elasticity of a spring 29. Then a driving wire 18 is held between a hand-down holding bar 25a and a fixed bracket touching part 23a. When a carriage functioning as an optical system is moved to the variable magnification position, the solenoid 24 is set under the conductive mode. As a result, a plunger 24a is pulled and the plate 25 turns clockwise centering on the ends 25b and 25c via an interlocking lever 26 and against the elastic force of the spring 29. Thus the locking state of the wire 18 is released, and the above-mentioned carriage can be displaced.

Title: Opto-thermal writing type spatial optical modulation element
Inventor: TAKIZAWA KUNIHARU
IPC: G02F1/137
Filed: 1990-03-28
Abstract: PURPOSE:To decrease the optical energy for writing and to write and display images without scanning by inputting the information on images and data patterns to the spactial optical modulation element by using writing light and two-dimensionally displaying this information by using reading out light. CONSTITUTION:The information on the images and data patterns is inputted to the spatial optical modulation element by using the writing light and this information is two-dimensionally displayed by using the reading out light. The spatial optical modulation element is constituted particularly of a guest-host type liquid crystal formed by mixing a dyestuff into a nematic liquid crystal, cholesteric liquid crystal or smectic liquid crystal. Bias heat is applied thereto and the information on the images and data patterns is inputted by the writing light having a wavelength within the light absorption region of the dyestuff. The information is displayed by the reading out light having the wavelength off the light absorption region of the dye. Since the double refractiveness of the liquid crystals is utilized in such a manner, the light energy for writing is smaller than the light energy for writing of the conventional opto-thermal writing type space optical modulation element. The two-dimensional and simultaneous writing/displaying is possible without scanning the information on the images and data patterns, etc.

IPC: B41J2/18
Filed: 1990-03-28
Abstract: PURPOSE:To eliminate wasteful ink consumption and ensure rapid ink supply by providing an ink pressure feed device which sends ink under pressure and a bypass route between a tank which stores ink to be fed to a recording head and the recording head. CONSTITUTION:An ink supply to a recording head unit 1 is performed by a pump 24 which is an ink pressure feed means provided in the route of a feed pipe 11 communicating with a tank 13. In addition, a bypass route which allows the feed pipe 11 to communicate with a return pipe 12 with passing through a liquid chamber 30 is provided. This bypass route is opened or closed by valves 403, 404 and during a routine recovery operation, a small quantity of ink is discharged from a discharge orifice 31 and thus the interior of the discharge orifice 31 and a head surface (not illustrated in the figure) are cleaned. Further, when the interior of a feed path communicates with an atmosphere due to the replacement of a recording head, the ink can be bypassed by opening the valves 401, 402 and closing valves 403, 404. Consequently, the ink consumption is reduced by limiting the ink ejection from the discharge orifice 31 to a minimum allowable extent.
