Patent JP-S57136226-A (JP)
Title: Power supply device of constant voltage
Inventor: OSADA YASUTO
IPC: G05F1/56
Filed: 1981-02-17
Abstract: PURPOSE:To realize a constant voltage power supply device having a small amount of heat generation and a reduced number of component parts, by comparing the value obtained by converting the output obtained by giving both-wave rectification to an AC input into a pseudo trapezoidal wave and then integrating the said trapezoidal wave with the value obtained by giving the division of voltage to a DC output and then controlling a thyristor with the output of comparison. CONSTITUTION:An AC input receives the full-wave rectification through a bridge rectifying circuit DS, and this output is applied to an anode of an SCRQ4 and also clamped by a Zener diode DZ2 through a resistance R5 to be changed into a trapezoidal wave. This trapezoidal wave is integrated by a resistance R6 and a capacitor C1 and applied to the anode of a programmable unijunction transistor TRQ5. On the other hand, the DC output voltage is divided by resistances R7 and R8 to be applied to the gate of the TRQ5. The TRQ5 is turned on when the gate potential exceeds the anode potential, and the SCRQ4 is triggered via a transformer T. When the DC output voltage increases, the trigger of the SCRQ4 is retarded. While the trigger of the SCRQ4 is accelerated when the DC output voltage lowers. Thus the DC output voltage is kept constant.

Title: Thermal head
Inventor: KANAMORI TAKASHI
IPC: H05K1/16
Filed: 1985-02-07
Abstract: PURPOSE:To raise the adhesion of a base plate and a heating resistor layer as well as lengthen the life of a thermal head by providing a heat-resistant resin layer free of denaturation between the base plate and the heating resistor layer. CONSTITUTION:When using a glass-epoxy base plate 11, for example, a heat- resistant resin layer 12 of polyimide resin, heat-resistant epoxy resin, etc., is coated on the base plate 11. Since the layer 12 is hardly denaturated, the adhesion with a heating resistor layer 13 can be raised and the life of the thermal head can be greatly lengthened. Also, since the resin layer 12 obtains high surface temperatures, the heating efficiency can be markedly enhanced.

Title: Atm network and method for avoiding fault or congestion in atm network
Inventor: OTA MASATAKA
IPC: H04L12/28
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To automatically set logic connection avoiding a fault part. SOLUTION: In-use logic connection between end systems (WS5-1 and 5-15) is established by header exchange tables 5-4, 5-6, 5-7, 5-9, 5-10 and 5-12 deciding routing in ATM exchanges 5-5, 5-8 and 5-11. A routing from the exchange 5-5 to an exchange 5-15 through an exchange 5-18 and a routing from the exchange 5-11 to WS5-1 through the exchange 5-18 are established by setting the tables 5-6, 5-7, 5-16, 5-17, 5-19 and 5-20 of the exchanges 5-5, 5-8, 5-18 and 5-11. When a fault occurs in a physical link between the exchanges 5-8 and 5-11, the tables of the exchanges 5-27 and 5-11 are rewritten and cells which the routing routes WS5-1 and 5-15 that are previously established transmit flow in. Thus, logic connection passing through the exchange 5-18 between WS5-1 and 5-15 is established and it is used instead of in-use logic connection.

Abstract: PURPOSE:To obtain a metallic thin strip uniform in sheet thickness in its width direction and small in strain after coiling work, by feeding a molten metal onto a rotating cooling-base-plate from a nozzle, whose opening part is turned by a prescribed angle and formed into a recessed surface of specific radium of curvature. CONSTITUTION:The bottom surface of a nozzle 1 is provided with a rectangular opening part 2 having the longitudinal direction slanted by an angle theta with respect to the direction (X-X) perpendicular to the moving direction of the surface of a roll 3. Further, the shape of the bottom surface 1a of nozzle 1 is formed into a recessed surface of radius R of curvature. The range of 5-20 deg. angle theta is preferable, and the range of 40-85% of the radius of a cooling roll 3 is suitable for the radius R or curvature.

In such manner, a metallic thin strip excellent in dimensions and quality can be obtained, by specifying the radius of curvature and slant angle of the bottom surface of nozzle in consideration of the diam. and expansion of the cooling roll used for manufacturing a thin strip.

Title: Semiconductor device
Inventor: YAMAMOTO MASANORI
IPC: H01L29/78
Filed: 1980-02-22
Abstract: PURPOSE:To lessen leak and improve yield while maintaining high antipressure properties, by making the surface concentration of the outermost circuit part of the P<-> type high antipressure layer with the surface concentration less than 10<17>cm<-3> on an N type Si substrate more than 10<17>cm<-3>. CONSTITUTION:In case of B implantation to an N type Si, if the surface concentration is less than 10<17>cm<-3>, inversion is apt to occur, while the concentration is more than the said level, inversion is hard to occur resulting in reduction of leak. The thermal oxidation is applied to the N type Si substrate 1 and a P<-> low concentration high pressure region 2 (base layer) is formed. On the outer circuit thereof a window is opened on the thermally oxidized film to perform B diffusion and form a high concentration region 3. Because of a field plate 9' the electric field adjacent to the surface 5 is weakened and the device part is filled with the depletion layer. The electric field concentration is at its peak in the outermost 7 region and the antipressure properties is determined by the region 7. Therefore leak can be prevented without giving effects to the properties of the high antipressure region 2. And the N layer 6 acts as either a source or drain with the N type substrate 1 acts as the other, and are controlled by a gate electrode 8 resulting in a stable properties.
