Title: Solid electrolyte type fuel cell
Inventor: HARUFUJI YASUYUKI
IPC: H01M8/12
Filed: 1992-09-01
Abstract: PURPOSE:To stabilize the sealing performance of a solid electrolyte type fuel cell by alternately laminating a unit cell and a gas supply means and arranging a gas sealing part in a predetermined part between the unit cell and the gas supply means and constituting the gas sealing part of a layered product made of metal and glass. CONSTITUTION:A solid electrolyte type fuel cell is constituted with a porous base substance 7 with a rib in which a unit cell 31 including an anode 1, a solid electrolyte substance 3 and a cathode 2 is formed and a porous base substance 11 with a rib in which an inconnector 12 is formed being alternately laminated. A fuel gas supply manifold 4 and an oxidant gas supply manifold 5 are provided in the central part of a layered product. In a fuel cell of such constitution, the base substance 7 in which the anode 1, the electrolyte substance 3 and the cathode 2 are formed, and the porous base substance in which the inconnector layer 12 is formed can be merely alternately laminated. Therefore, since the base substance 7 and the base substance 11 are mutually and freely movable in the process of thermal expansion, a thermal stress is not generated. Also, since the gas sealing part 6A, 6B is formed in laminated structure, a thermal stress is not generated.

Title: Production of color filter for liquid crystal display
Inventor: MATSUMURA NOBUO
IPC: G02B5/20
Filed: 1992-09-01
Abstract: PURPOSE:To obtain an inexpensive and high-precision color filter by laminating a silicone rubber layer on a specified pattern, then removing the patterned photosensitive resin layer along with the silicone rubber layer and coloring the exposed part with three red, green and blue primary colors. CONSTITUTION:A photosensitive resin layer is formed on a transparent substrate, and then the photosensitive layer is exposed and developed by photolithography to form a specified pattern. A silicon rubber layer is then laminated thereon, the patterned photosensitive layer is removed along with the silicone rubber layer to form the parts freed of the silicone rubber layer in a specified pattern, and then the exposed parts are colored with the three red, green and blue primary colors. Meanwhile, the photosensitive layer is irradiated with an active beam and solubilized. Consequently, the blotting of ink and color mixing are prevented even when the colored part is formed by printing or the ink-jet method.
Patent JP-H04113215-A (JP)
Title: Torque balancer
Inventor: YAMAGUCHI TAKAO
IPC: G01P15/13
Filed: 1990-09-04
Abstract: PURPOSE:To prevent displacement from being generated in a direction where a movable coil is rotated when the movable coil is displaced due to shock, etc., by allowing a direction where a pin of a band-locking tool is placed to be in parallel with a direction where a weight is placed in reference to the center of the movable coil. CONSTITUTION:Even if a shock is applied, a movable coil 22 can be displaced only in axial direction of pins 26a and 28a since it is wound around the pins 26a and 28a of band-locking tools 26 and 28 and is supported by torsion bands 34b and 36b are subjected to friction-contact. Therefore, the movable coil 22 can be displaced only in upper and lower directions. Even if the movable coil 22 moves in upper and lower directions, there is no positional change of a circular plate 40 in directions of photoelectric interrupters 42 and 44. Namely, while no outer force is applied, the circular plate 40 is retained at a middle position between the photoelectric interrupters 42 and 44, thus preventing zero point from being deviated even in case of shock application.

Title: Color picture tube
Inventor: MUTO SATOSHI
IPC: H01J29/07
Filed: 1992-09-01
Abstract: PURPOSE:To provide a color picture tube whose manufacturing yield is increased by raising the limit of external forces exerted on the bottom portion of a mask frame and causing deformation of the effective surface of a shadow mask mounted on the mask frame. CONSTITUTION:In a color picture tube which has a built-in mask frame 1 having a shadow mask 7 partially welded at its mask skirt portion 9 to the welding area 4 of a mask-frame side wall 3, the mask frame 1 is curved at its end area 5 ahead of the welding area 4 of the side wall 3, in the inward direction of the side wall 3 and at least near said welded portion; during the manufacturing process of the color picture tube, the end area 5 is therefore prevented from pressing the inner surface of the mask skirt portion 9 with an external force exerted on the mask frame 1 and so does not cause deformation of a mask effective surface 8; therefore the manufacturing yield of the color picture tube is increased.

Title: Dynamic ram
Inventor: WATANABE SHIGEYOSHI
IPC: G11C11/407
Filed: 1982-12-27
Abstract: PURPOSE:To increase pattern area and reduce the complexity of a pattern and a circuit with regard to wiring material, i.e. polycrystal silicon, and to realize high-speed operation by providing a high-speed transfer circuit which accelerates variation in word line potential in the middle of a word line. CONSTITUTION:For example, a row decoder 12m selects a word line 131m to turn on an MOS FETQ6, and to set a driving signal phiin at a high level. In this case, the potential of the word line 131m rises. At this time, when the length of the word line is long, the time constant is large and rising is delayed. For this purpose, the high-speed transfer circuit 14m is provided, and then when the potential at the node N4 at the terminal of the word line 131m rises, nodes N5 and N6 are precharged to a source voltage VDD. At this time, the rising of a word line driving signal phiin' is delayed slightly behind a signal phiin and supplied to speed up potential variation at the node N8 at the terminal of a word line 132m. Therefore, the charging time constants of word lines are decreased apparently, so an input selection signal is transferred to the terminal part at a high speed.
