Title: Method and apparatus for peeling laver sheet
Inventor: ICHIKAWA KAN
IPC: A23L17/60
Filed: 1981-03-20
Abstract: PURPOSE: To release a laver sheet from a laver screen, with little damage of the sheet, in high efficiency, by holding the middle part of the screen, stretching the screen longitudinally thereby preliminarily peeling the laver sheet, transferring the screen while pressing down its front part, and transferring the laver sheet to the suction means.  
     CONSTITUTION: A laver screen 5 having a laver sheet 7 attached to its lower face is transferred intermittently. At the stationary stage of the screen 5, the middle part of the screen 5 is clamped with the lower clamping member 9 having an elastic holding material 9a and the upper clamping member 8 having a compression spring 13, and at the same time, the hooking members 17 and 18 having hooks 18a and 17a are lowered to stretch the screen longitudinally and to effect the preliminary peeling of the sheet 7. The calmp of the middle part and the longitudinal stretching are released, and the screen is forwarded by one pitch. The pressing roller 34 is lowered to effect the suction of the laver sheet 7 with the suction transfer means 27, and the laver sheet is separated from the laver screen by the suction means 32 and the feed roller 33.

Title: Optical semiconductor element and its manufacture
Inventor: ISSHIKI KUNIHIKO
IPC: H01L21/20
Filed: 1992-02-27
Abstract: PURPOSE:To cause a light confining ratio, inhibited band width, coupling condition of light, etc., to be changed by layer thickness change in an element and to make the element characteristics better, by making the thickness of the active layer of a laser diode part smaller than that of the active layer of a photodiode part on a semiconductor substrate. CONSTITUTION:The thickness of the active layer 3a of a photodiode part 10 is made smaller than that of the active layer 3 of a laser diode part 9. The thinner part of the layer is used as a laser diode part 9, and the thicker part is as a photodiode part 10. When forward voltage is applied between both electrodes 7 of the laser diode part 9, a laser beam is emitted in a direction shown by an arrow 8. While, light emitted from an etched mirror 6 irradiates the active layer 3 of the photodiode part 10 and is absorbed, and current flows. On this occasion, the confined ratio of the incident laser beam becomes larger, since the film thickness of the active layer 3a of the photodiode part 10 is larger than that of the active layer 3 of the laser diode part 9.

Title: Electrophotographic sensitive body
Inventor: HIRAYAMA NORIKO
IPC: G03G5/07
Filed: 1990-02-23
Abstract: PURPOSE:To enhance durability and adhesiveness of a photosensitive layer by forming a coating film containing a polysilane and conductive particles on a metallic substrate and backing it into a ceramic state to form a conductive layer. CONSTITUTION:The coat film containing the conductive particles and the polysilane is formed on a metallic substrate and backed to >= 300 deg.C into a ceramic state to form the conductive layer. The polysilane is allowed to form Si-C bonds to convert it into the ceramic superior in strength, hardness, abrasion resistance, heat resistance, and corrosion resistance but low in conductivity, therefore, it is preferred to add the fine conductive particles in order to use it for the conductive layer of the phtosensitive body. The fine conductive particles can be embodied by particles of SnO2, In2O3, TiO2 treated to enhance conductivity, and carbon, and the like or powders of Al, Cu, Fe, and the like, thus permitting high image-quality to be maintained at the time of repeated uses, high in resistance to cracking and peeling, and enhanced in adhesiveness.

Abstract: PROBLEM TO BE SOLVED: To form a completely round beam spot on a fluorescent screen and to improve resolution by forming the aperture of the electrode of an electron beam driving system on the cathode side than a main lens system electrode of an electron gun into an ellipse. SOLUTION: The electrode of an electron beam driving system for extracting an electron beam from a cathode K, e.g. first and second grids G1, G2, is formed into a bottomed cylindrical shape, an aperture 16 is bored at the center position of the bottom in an oblong elliptic shape, thereby the prescribed electrode of an electron gun is made astigmatic, and the magnifying power of an image in the Y-axis direction can be reduced. No electric control is required for making an electron beam astigmatic by merely forming the aperture 16 of the electrode of the electron beam driving system such as the first grid G1 or/and the second grid G2 into the oblong elliptic shape. An oblong elliptic spot 17 is formed on a virtual vertical plane 13, however a completely round spot 18 is obtained on an inclined fluorescent plane 5 due to astigmatism, and resolution can be improved.

Title: Apparatus for controlling parison injection in intermittent and multi-layer blow-molding machine
Inventor: MOTONAGA TAKATOSHI
IPC: B29C49/78
Filed: 1986-02-27
Abstract: PURPOSE:To prevent the reduction in thickness of an additional resin at the early stage of injection, by elevating the injection pressure of the additional resin by a specified pressure from the pressure set at the beginning by means of injection controlling device and then by returning the pressure to the set value. CONSTITUTION:A main resin is supplied from storage rooms 16, 20 to a supplying part 21 and plungers 16a, 20a are elevated correspondingly. Piston rods being connected with the plungers 16a, 20a are elevated to the top end position and a device 24 detecting the plunger position outputs a starting signal A1 of parison extrusion to a parison controlling circuit 25. The main resin constituting the lower mono-layer parison is extruded from an extrusion nozzle on this output signal and an additional resin is then extruded by the output of a solenoid 43a. It is possible to prevent the thickness from becoming thin at this stage of the process by bringing the pressure of the additional resin at the early stage of injection a little higher than the set pressure.
