Title: Fuel cell stack
Inventor: SETA YOUICHI
IPC: H01M8/02
Filed: 1982-05-21
Abstract: PURPOSE:To reduce leak of fuel gas and increase utilization of fuel gas in a fuel cell having reflux type gas flow path by making larger the space in a boundary between feed path side and return path side in a fuel gas supply groove than that of other supply groove. CONSTITUTION:A fuel gas flows from a feed path side section 31 of a gas manifold 3, through a feed side gas supply groove 41 of a bipolar separator 2, to a gas manifold on the opposite side, and flows through a gas supply groove 42 on the return path side and returns to a return path side section 32 of a gas manifold, and is exhausted to the outside. The space l2 in a boundary 5 between the fuel gas supply groove 41 on feed path side and the fuel gas supply groove 42 on return path side in the bipolar separator 2 makes larger than a space l1 between other supply grooves. When the space l2 makes wider, leak of fuel gas from the boundary is lowered but effective area of electrochemical reaction is decreased. Therefore, it is preferable to increase the space l2 by three or four times than the space l1 to increase utilization of fuel gas.

Abstract: PURPOSE:To form an excellent crystallized film, in which no fine crack is generated and into which impurities are not mixed, by forming the film density of the upper layer section of a first insulating film and a second insulating film in density higher than the film density of the lower layer section of the first insulating film and applying laser beams. CONSTITUTION:A first insulating film 2, an amorphous or polycrystalline semiconductor thin-film 3 and a second insulating film 4 are shaped onto a substrate 1. The forming method of the semiconductor thin-film is that these films are formed and the semiconductor thin-film is crystallized by irradiating the thin-film with laser beams. The film density of the upper layer section 2b of the first insulating film 2 and the second insulating film 4 is formed in density higher than the film density of the lower layer section 2a of the first insulating film 2 and laser beams are applied at that time. The substrate 1 is composed of glass, quartz, ceramics, etc. The first insulating film 2 is constituted of the lower layer section 2a on the substrate 1 and the upper layer section 2b formed onto the lower layer section 2a, and shaped of silicon dioxide. According to such constitution, the generation of stress due to thermal expansion is relaxed in the lower layer section of the first insulating film formed through a CVD method. The mixing of impurities into the semiconductor thin-film is prevented by the upper layer section of the first insulating film formed in high density and the second insulating film.

IPC: G11B7/26
Filed: 1993-04-13
Abstract: PURPOSE:To form high-accuracy rugged patterns by developing the exposed parts of a resist layer by a dry processing. CONSTITUTION:The shapes of the rugged patterns formed by the development by the wet processing are varied largely by a slight dispersion in developing conditions, such as temp. and concn. of a developer and a difference in the wettability of the developer with the surface of the resist layer in the case of this development. The development by the dry processing is executed in order to prevent these defects. The resist layer 2 is formed on a master disk 1 and the exposed parts 3 thereof are removed by exposing the layer 2 according to the prescribed information of the optical recording medium. The rugged patterns 4 meeting the prescribed information are formed by the development by the dry processing. The stamper 7 for the optical recording medium is produced in such a manner. A material contg. a compd. formed by acetylating or alkylating polyterminals as a chief material is used at the time of forming the resist layer. The resist layer is subjected to a heat treatment process then to the development by the dry processing to form the rugged patterns meeting the information of the optical recording medium. The stamper having the high performance and high quality is thus produced.

Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To accurately generate the cross-sectional profiles in the width direction or the longitudinal direction by forming the shapes of the slits which pass radioactive rays in a thin and long shape along the width or the longitudinal directions with respect to the object to be measured. SOLUTION: A slit plate 2, which is made of lead or tungsten alloy, limits and passes the radioactive rays from an X ray generator. A first slit 12 which is thin and long in the width direction of the object to be measured and a second slit 13 which is thin and long in the longitudinal direction are formed on the plate 2. The plate 2 is moved forward and backward in an arrow sign 15 direction by an air cylinder 16 through cylinder rods 17 and the shape of the radioactive rays, which irradiate the object, is limited so that the shape is made thin and long in the width direction or the longitudinal direction. Thus, the slit 12 provides more information on the width direction of the object to a radioactive ray detector and the slit 13 yields more information in the longitudinal direction of the object to the detector.

IPC: G03G15/08
Filed: 1984-04-28
Abstract: PURPOSE:To apply toner charge which is stable for a long period of time without sticking of a non-magnetic one-component toner, etc. by using a metallic blade for a control member which forms the toner on a carrying body for conveying the toner received from a hopper to a thin and uniform layer.

On the other hand, a resin molding material is used for the body 4. Sticking and filming of the toner to the blade 3 as a result of repeated uses and generation of fogging and uneven density as in the case of the conventional non-metallic blade made of urethane rubber, etc. are thus obviated. The substantial electric charge is applied to the toner and the sharp image is obtd. and the wear and failure of the blade 3 which arise when the metallic body 4 is used are decreased. The life of the blade is thus extended.
