Abstract: PURPOSE:To efficiently perform the changeover of wiring in case of using the function of redundancy by a method wherein two wiring means constituted of Si are formed, and the other wiring means is put in the state of connection, when one of the wiring means is provided in a cut-off state at a time of heating. CONSTITUTION:A functional circuit block 84 for redundancy used in place of actual functional circuit blocks 81-83 is provided. N<+> type regions 87-89 having impurity density higher than that of a substrate are formed respectively on the surface region of the substrate at each access part of a pair of P<+> type regions 85 and 86. The wiring means 90-92 are electrically in a cut-off state in beginning state, since N<+> type regions of different conductivity types exist between a pair of the P<+> type regions each other. Because an impurity is introduced into conductive layers 93-95 resulting in low resistance, the both ends are electrically in the state of connection. In case of using the functional circuit block 84 for redundancy, the region whereat the wiring means 90 and the conductive layer 93 intersect with each other is heated.

Abstract: PURPOSE:To permit stripping of an extremely thin photosensitive emulsion layer on which an image is photographed by heating photographic paper to a prescribed temp., then sticking a stripping operation body to the surface of the photographic paper and peeling this stripping operation body. CONSTITUTION:The photographic paper A subjected to printing and developing processes is heated to the prescribed temp. to melt the adhesive layer 2 of the photographic paper A. After the adhesive layer 2 is melted, the stripping operation body B formed by sticking a film 8 consisting of a hot-melt type adhesive resin strippably to the rear face of a carrier film 7 is superposed on the photographic paper A and is heated. The resin film 8 is thus melted and the photosensitive emulsion layer 4 of the photographic paper A is adhered to this resin film 8. The stripping operation body B is thereafter peeled from the photographic paper A and the photosensitive emulsion layer 4 is stripped from a reinforcing paper piece 1. The time for the stripping operation of the photosensitive emulsion layer 4 is thereby shortened and the easy stripping operation even by an unskilled person unlike in the conventional method is permitted.

Title: Resin molded coil
Inventor: KUBO HIROBUMI
IPC: H01F27/32
Filed: 1987-03-18
Abstract: PURPOSE:To improve insulation between a primary coil and a secondary coil and to implement compact configuration, by providing an insulator between the primary coil and the secondary coil, and forming an insulating layer so that it has a dielectic constant close to the dielectric constant of air. CONSTITUTION:A resin 14 is injected also between a primary (high voltage) coil 3 and a secondary (low voltage) coil 2. An insulating layer 14a, which has a dielectric constant close to the dielectric constant of air, is formed between the primary coil 1 and the secondary coil 2. Many cavities formed with minute hollow parts 5 are present in the insulating layer 14a such as this. Even if voids are yielded in the insulating layer between the primary coil 3 and the secondary coil 2, an electric field is shared with the many cavities formed with the minute hollow parts 5 and the voids approximately evenly. Therefore, the concentration of the electric field to the voids can be prevented. When the minute hollow parts are filled by 4.0-70 volume %, the specific gravity of the resin 14 can be made as small as 0.7-1.0. Thus the weight of the product can be largely decreased.

Title: Bleeder resistor
Inventor: KUKIDA MEIJI
IPC: H01C1/024
Filed: 1988-03-15
Abstract: PURPOSE:To obtain a superior pictorial image, by causing a high-voltage input wire and an injected resin to be not charged with static electricity in such a way that the high-voltage input wire from a fly-back transformer and a bleeder resistor are not disposed in parallel between the bleeder resistor and an outer packaging casing. CONSTITUTION:A high-voltage input wire 20 is not disposed at a position which is in the vicinity of a bleeder resistor 19 housed in an outer packaging casing 16 and is parallel to its resistor. The high-voltage input wire 20 and a high- voltage output wire 22, to the point of which an anode cap 21 is connected are connected to the other end of the resistor 19. When a high-tension reactive current flows in this resistor, slight voids which develop between the input wire 20 and an injected resin 26 or an inside coated part and an outer packaging coated part of the input wire 90 are not charged with static electricity. Thus, spark and corona discharges generated between the resistor and input wire prevent this device from generating a noise in a projected image. Thus, a superior pictorial image is obtained.

Title: Digital servo controller
Inventor: SEKIGUCHI HIDENORI
IPC: G05B13/00
Filed: 1986-03-19
Abstract: PURPOSE:To facilitate securing the safety of a control system by detecting the state variable of a prescribed part of a controlled system and that of a part other than the prescribed part and minimizing the deviation of the part other than the prescribed part from a rigid body to suppress oscillation. CONSTITUTION:The state variable of a prescribed part of a controlled system 101 is detected by a detecting part 111, and that of a part other than the prescribed part is detected by an oscillation detecting part 103. The deviation between a reference input to the prescribed part and a reference input to act as the rigid body to the part other than the prescribed part is operated by a reference input element 105. A part of the deviation of the prescribed part obtained in this manner is integrated by an integrator 107 to obtain an integral quantity. An optimum regulator 108 uses the state feedback gain based on the optimum regulator logic to convert an input signal to a conversion signal so that these deviation and integral quantity are minimized simultaneously. Thus, the controlled system 101 acts like a rigid body as the whole, and oscillation due to the non-rigid body property of the controlled system is suppressed not to damage the safety of the control system.
