Title: Sheet curl straightener
Inventor: NISHIMURA KATSUHIKO
IPC: B65H23/34
Filed: 1987-04-27
Abstract: PURPOSE:To prevent a sheet from adhering to a rotor on one side by installing an application member additionally adjoining to the rotor on one side and applying a remover to it, in case of a sheet curl straightener consisting of a pair of rotors. CONSTITUTION:The curled sheet S heated and pressurized and fixed with a toner image by a fixer is fed to a curl straightener 22, and it is held between a rigid roller 22c, coating a stainless roller 22a with Teflon 22b, and an elastic roller 22d, thus its curl is straightened. At this time, since the rigid roller 22c is coated with silicone oil over the whole surface by a pad 37 of an applicator 36, the sheet S is easily separated from the rigid roller 22c and discharged out by way of a discharge roller pair. Thus, such a possibility that the sheet is recurled is preventable by the sheet curl straightener.

Title: Semiconductor integrated circuit
Inventor: KOTANI HIROSHI
IPC: H03K19/086
Filed: 1983-06-15
Abstract: PURPOSE:To improve the SN of the IC by forming a resistive element in an input stage onto an island of N layer on which transistor (TR) elements of the input stage are formed so as to prevent the effect of fluctuation of a power supply voltage at an output stage from being given to the input stage through the resistive element. CONSTITUTION:When a TR formed on the island of N layer is a TRQ1 or Q2 in a current switch CS, a P diffusion layer formed on this island corresponds to a resistor R1 or R2. On the other hand, when the TR formed on this island is a TRQ4 or Q5 for emitter follower, the diffusion layer 8 on this island corresponds to a resistor R4 or R5 for emitter follower. Further, the resistors R1- R3 constituting this current switch circuit are formed on the island of N layer on which the TRQ1-Q3 constituting this circuit are formed. Thus, even if a power supply voltage vcc1 is fluctuated because of a large current flowing to the TRsQ4, Q5, the configuration precludes the possibility of noise from giving to the current switch circuit side.

Title: Method for detecting surface detect of water-stopping type rubber/plastic insulation power cable water-stopping layer
Inventor: UEMATSU TADAYUKI
IPC: G01N25/16
Filed: 1991-05-10
Abstract: PURPOSE:To enable deterioration state of a metal foil of a water-stopping layer to be evaluated simply and properly by giving a specific range of distortion to the metal foil by heating the water-stopping layer and then coating a penetration flaw-detecting liquid for penetration into a surface defect and then performing cooling. CONSTITUTION:A water-stopping surface which is constituted by a metal foil of a compound tape and a plastic film is heated, thus enabling a thermal expansion distortion of 0.5-7.0% to be given to the metal foil. Then, the penetration flaw-detecting liquid is coated on the surface of the expanded metal foil, thus enabling the penetration flaw-detecting liquid to be penetrated into an opening of the surface defect. Then, when the compound tape is returned to a normal temperature, the surface defect of the metal foil is also closed by shrinkage of the plastic film and the penetration flaw-detecting liquid which is penetrated into the opening is squeezed out, thus enabling the defect portion to be dyed. When a distortion which is given to the metal foil is less than 1.5%, the surface defect will not be opened fully, thus preventing the penetration flaw-detecting liquid from being penetrated to a small defect. Also, when the distortion is larger than 7.0%, a8 new defect is generated at the metal foil which is fragile due to fatigue.
