Title: Liquid crystal display cell
Inventor: OOTAKI TOSHIHIRO
IPC: G02F1/1333
Filed: 1983-04-19
Abstract: PURPOSE:To obtain a liquid crystal display cell superior in sharpness and brightness, and suitable for enlargement of its size and formation of a curved face by sealing in liquid crystals between oriented plastic films having their principal orientation directions crossing each other at right angles, and a specified difference of retardation values between them. CONSTITUTION:Liquid crystals are sealed in between two oriented plastic films having their principal orientation directions crossing each other at almost right angles and the difference of retardation values between them not below 200mum. Said principal orientation direction means the direction in which its refractive index becomes max. When said principal orientation directions are parallel to each other, the yield of production of the liquid crystal display cell is low, and raises its cost, so it is not desirable. Twisted nematic type, guest-host type, and dynamic scattering type liquid crystals are used, and above all, the twister nematic type liquid crystals are preferable.

Title: Image pickup device
Inventor: HARADA TOSHIAKI
IPC: H04N5/335
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To allow one and same image pickup device to pick up a moving image and a still image. SOLUTION: An optical system 3 of the image pickup device 1 separates an image light from a subject into a plurality of monochromatic image lights and an image pickup means 4 picks up the image to generate an original image signal. The device 1 selects the image pickup device mode depending on the output mode. The optical system 3 selects a state of a variable spatial filter 18 depending on the image pickup mode to revise a spatial frequency limit effect. In the case of the moving image output mode, an interpolation synthesis circuit 7 generates an output image signal from the single original image signal.  In the still image output mode, while the image pickup means 4 moves the optical axis of the incident image light in parallel by an image shift device 19, the image pickup means 4 picks up the plural original image lights and then an output image is generated from the original image signals. The attenuation of a filter 18 in the moving image output mode is higher than the attenuation in the still image output mode from the standpoint of the same spatial frequency component.

Title: Injection mold
Inventor: KIYOMOTO SHUICHI
IPC: B29C45/26
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To prevent burrs from developing through the deflection of a movable retainer plate due to the generation of an impact force by a method wherein a molding material is made to flow in a pressure absorbing space after the molding material fills a cavity. SOLUTION: When a molding material is poured through a sprue 8 from an injection molder, the molding material fills through respective runners 9 and gates 10 respective cavities 11. When the filling of the molding material completes, the molding material further flows in respective pressure absorbing spaces 18. Accordingly, since the pressure of the molding material is absorbed due to the flow of this molding material happening after its filling of the cavities, the abrupt rise of the pressure in a mold is suppressed, resulting in eliminating the conventional development of a large impact force at the completion of the filling of the cavities. As a result, burrs can be prevented from developing at a parting surface 7 through the deflection of a movable retainer plate 3 and a back up plate towards an ejector space due to the generation of this impact force.

Title: Engine power generating equipment operating controller
Inventor: WAKITANI TSUTOMU
IPC: H02M7/48
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To supply the output of an engine power generator to load in preference for highly efficient operation of engine power generating equipment, by setting DC output voltage rectifying the AC output of an engine generator so that it may not be lower than that of a commercial power system or the like. SOLUTION: When engine revolutions have risen sufficiently to a normal condition, if the DC output voltage Veg 0 of an engine generator is set higher than the DC output voltage Vac 0 of commercial power supply, the DC output voltage Veg 0 of a converter 13 becomes higher than the output Vac 0 of the commercial power supply, so that a diode 24 on commercial power supply side is in a reverse-bias condition and its continuity is inhibited. A diode 14 is in a forward-bias condition, therefore power supply to load 35 through an inverter 30 is conducted from an engine generator 12, so that an engine generator 10 covers total load current, and commercial power supply 20 supplies no load current. It is thus possible to make effective use of power generating capacity by operating power generating equipment under operating conditions with the highest efficiency.
