Title: Tn type liquid crystal display element
Inventor: KAWAHARA YUKIO
IPC: G02F1/137
Filed: 1990-10-17
Abstract: PURPOSE:To obtain a good visual angle characteristic which fewer phase plates by interposing one sheet of the phase plate having the optical axis in the direction nearly equal to the transmission axis direction of a 1st polarizing plate between the 1st polarizing plate and a TN type liquid crystal cell. CONSTITUTION:One sheet of the phase plate 22 having the optical axis 24 nearly equal to the transmission axis direction of the 1st polarizing plate 12 is interposed between the 1st polarizing plate 12 and the TN type liquid crystal cell 11. A retardation arises between the vibration (1st light) of the light in the optical axis 24 direction of the phase plate 22 and the vibration (2nd light) of the light in the direction orthogonal therewith and the polarization state of the light changes if incident light passes the phase plate 22. Only the 1st light vibrating in the optical axis 24 direction of the phase plate 22 is, however, transmitted, if the transmission axis directions 16, 17 of the polarizing plates 12, 13 are parallel with the optical axis 24 direction of the phase plate 22 and, therefore, the transmission quantity of the light is constant regardless of the presence or absence of the retardation. The reduction of the phase plate 22 to one sheet is possible in this way and the stage for sticking films is simplified. The production is facilitated and this initial cost is reduced.

Title: Manufacture of fuel electrode for molten carbonate fuel cell
Inventor: ITO YASUHIKO
IPC: H01M4/86
Filed: 1989-10-25
Abstract: PURPOSE:To precipitate salts of dissimilar metals as metal oxides on the surface of nickel particles so as to prevent sintering and creeping of a fuel electrode as a result of the long-range use of the fuel electrode by mixing nickel powder and salts of disimilar metals together, and molding them into a sheet, and then subjecting the sheet to heat treatment prior to sintering. CONSTITUTION:Carbonile nickel power, cobalt nitrate powder, polyvinyl butyral powder and polyethylene grycol dioctyl phtalate are dispersed and mixed in ehtanol and water both serving as a solvent, to form a slurry. The slurry is molded into a green sheet using a doctor blade etc., and after drying the sheet is subjected to heat treatment in air at about 400 deg.C. By the heat treatment binding agent and plasticizer are decomposed and removed from the sheet and the cobalt nitrate is thermally decomposed and precipitated as cobalt oxide on the surface of Ni particles. Next, the sheet is sintered in reducing atmosphere at 800 deg.C to obtain a fuel electrode 2; then the cobalt oxide is reduced to metallic cobalt.

Title: Flashing device for small-sized variable power camera
Inventor: HIROHATA MICHIRO
IPC: G03B15/05
Filed: 1986-11-22
Abstract: PURPOSE:To prevent the occurrence of a red eye phenomenon and an eclipe due to a mirror barrel by positioning a light emitting part almost perpendicularly if a photographing optical system falls in a longer focus point, and positioning and tilting forward the part if the system falls in a shorter focus point. CONSTITUTION:If the photographing optical system falls in the shorter focus side, a stroboscopic light emitting part 2 is positioned so that, with a click spring 4 fitted in a click groove 2d, it can tilt forward and protrude. As for a decrease in the peripheral luminous energy of the photographing optical system, the peak of luminous intensity falls in a vertical position with respect to the center. If the photographing optical system falls in the longer focus point, the stroboscopic light emitting part 2 is positioned so that the click spring 4 is fitted in a click groove 2a. Hence the part 2 becomes almost perpendicular, protrudes forward a camera main body, and projects stroboscopic light far away. Thus if the system falls in the longer focus side, the light emitting position is the farthest from the optical axis of the photographing optical system to prevent the red eye phenomenon. On the other hand, if the system is on the shorter focus side, the forward tilt of the light emitting part can prevent the influence of an eclipse, which is caused by the mirror barrel.

At this time, the conveyor 6 consists of two lines of parallel link chains and flights 63 and each one link thereof is constituted as the screen block and, therefore, the scum and the coarse dust are surely captured. The captured coarse dust falls into a hopper 5 for discharging the coarse dust where the coarse dust is recovered when the conveyor 6 arrives at a turning point. The scum is separated by washing water and is dropped into the flow water trough 4 for discharge. The soild grit in the grit washing tank 2 is scraped up by the flights 63 and is discharged into a grit discharge hopper 3.

Abstract: PROBLEM TO BE SOLVED: To reduce transmission information amount in the case of transmitting coding data of a dynamic image. SOLUTION: Two kinds of data structures are stored in a storage device 103. The 1st data structure is a table of a bit string of coded data. The 2nd data structure is used to express coding rules and consists of strings of link information pointing out the 1st data structure. Furthermore, in the 2nd data structure, binary information representing whether or not a code word is to be sent to a receiver side is added to each element. A coded data correction device 102 collates a received bit string from an input terminal 101 with a bit string table of the 2nd data structure to decide transmission set/clear to the receiver side according to the binary information. The operation above is applied to a bit string received sequentially according to the order represented by the 1st data structure.
