Title: Plane sealing assembly
Inventor: GIRUBAATO FUREDERITSUKU TERIAA
IPC: F16L23/20
Filed: 1990-09-21
Abstract: PURPOSE: To prevent fluid leakage under a high temperature, a high pressure, or other un-advantageous operation environment by providing an annular seal member and grabbing it between a pair of relatively thin film gaskets made of selected seal material. CONSTITUTION: A face seal assembly 10 has a central seal member 16 sandwiched in a substantially coaxial relation between a pair of substantially engagement shaped film gaskets 18. The seal ring 16 is coaxially inserted between the pair of film gaskets 18 made of selected seal material such as polymer material, and the resultant layered product forms the face seal assembly 10. The film gaskets 18 prevent direct contact between the seal ring 16 and its adjacent housing components 12 and 14, and additionally provides high quality fluid seal between these components. Therefore, the film gaskets 18 effectively prevent generation of structural damage on the housing components.

Title: High breakdown strength low resistance semiconductor device
Inventor: TERAJIMA TOMOHIDE
IPC: H01L29/78
Filed: 1990-09-18
Abstract: PURPOSE:To make the gradient of an electric field gentle and to improve the breakdown strength by selecting the impurity concentrations and thicknesses of the first, third layers so that an electric field by a depleted layer extending from the P-N junction formed by first and third semiconductor layers exists largely in the first layer and that the depleted layer reaches a second semiconductor layer. CONSTITUTION:An N<-> type layer 21 is reduced in its sectional area from a P-N junction toward an N<+> type substrate 1, an N<--> layer 22 is formed instead. When a low potential is applied to an electrode 7 and a high potential is applied to an electrode 8, a depleted layer from a P-N junction formed with a P<+> type layer 3 and the layer 21 is extended in the layer 21 as the applied voltage is raised to reach the substrate 1. That is, the shape of the depleted layer is also formed in a shape similar to that of the layer 21. Since the layer 3 has a high impurity concentration, the depleted layer is not almost extended to the side of the layer 3. The layer 21 is reduced in its sectional area from the layer 3 toward the substrate 1. If the electrode 7 and a gate electrode 6 are set to a low potential and the drain electrode 8 is set to a high potential, i.e., in an OFF state, it can be supported by the layer 21 thinner than the layer 2. Thus, when the electrode 6 is a high potential, i.e., in an ON state, its resistance is reduced.

Title: Variable attenuator
Inventor: OKUYAMA SHIGEHITO
IPC: H03G3/30
Filed: 1986-10-20
Abstract: PURPOSE:To improve the attenuation characteristic of signal and the voltage standing wave ratio (VSWR) by providing a bias current reverse flow preventing means preventing a bias current from being allowed to flow to a 1st diode and a bias current bypass circuit branching a bias current from a connecting point between a 2nd diode and the 3rd diode. CONSTITUTION:A diode D10 prevents a bias current IB1 flowing to PIN diodes D1, D2 from flowing to a path of a PIN diode D3. Further, a resistor R3 branches the bias current IB1 always flowing to the PIN diode D1. A large attenuation is assured even at a region where a control voltage is low by preventing the flowing of the bias current VB1 to the PIN diode D3 by the intervention of the diode D10. Moreover, a minute current flows to the PIN diode D1 through the resistor R3, the VSWR of the circuit is kept excellently even at a region whether the control voltage VB2 is high to keep stable operation of the variable attenuator.

Title: Electrode material for metal-halogen secondary battery
Inventor: TANAKA TOSHIO
IPC: H01M4/96
Filed: 1988-10-05
Abstract: PURPOSE:To increase the utilization factor of surface area and reduce the overvoltage by using as a halogen electrode a cloth containing a porous carbon fiber having a specified amount of acidic group for the unit surface area. CONSTITUTION:A cloth containing a porous carbon fiber having an acidic group amount of 0.7mueq/m<2> or more for the unit surface area is used. The acidic group means hydroxyl group and carboxyl group on the carbon fiber surface. A cloth containing a porous carbon fiber in which the amount of the acidic group is 0.7mueq/m<2> or more, preferably 0.8-5.0mueq/m<2> to the unit surface area is adhered to an electrode base material and used as a halogen electrode. When the porous carbon fiber having the acidic group amount less than 0.7mueq/m<2> is used, the utilization factor of the surface area is reduced, and the electrode activity expected from the specific surface area can not be provided. Hence, the utilization factor of the surface area is increased and the overvoltage is reduced.
