Title: Holding current selector circuit
Inventor: SAGAWA AKIO
IPC: G01R31/26
Filed: 1980-07-02
Abstract: PURPOSE:To measure and select the holding current of a thyristor in a short time, by causing a constant current of the rated value to flow into the thyristor beforehand, applying on/off signals from a gate terminal, and detecting the conductive or nonconductive state at that time. CONSTITUTION:When constant current Is is applied from a constant-current generator circuit 10 to a thyristor 1 to be measured, anode potential VAK reaches the saturated voltage of the constant-current generator circuit 10. Here, an on signal VG is applied to the gate terminal 4 of the thyristor 1 to once make the thyristor 1 conductive. When the on signal VG is removed from the gate terminal 4, the thyristor 1 returns to the nonconductive state, if the holding current IH of the thyristor 1 is larger than the reference current Is. Whereas, if the holding current IH is smaller than the reference current IS, the thyristor retains the conductive state. Namely, the holding current is selected by detecting the conduction state of the thyristor 1 with the use of a comparator 11, when the on signal VG is removed from the gate terminal 4 of the thyristor 1. Through said constitution, the holding current is measured and selected in a short time.

IPC: C23C26/00
Filed: 1993-03-24
Abstract: PURPOSE:To provide a surface treatment technique by electric discharge machining capable of forming a smooth and uniform coating layer even in the case of a thin surface coating layer. CONSTITUTION:A gas which does not form toxic gases by electric discharge is supplied together with a working liquid between working electrodes, or, the current which can suppress the rise of a discharge current is passed to decrease the discharge trace current density at the time of depositing a conductive or nonconductive material by pulse electric discharge machining on the surface of a material to be surface treated. The splashing of the deposited layer induced by the explosive pressure generated by the discharge is thereby suppressed and the smooth and uniform surface coating layer is obtd. Argon, helium, carbon dioxide or gaseous nitrogen is used as the gas which does not form the toxic gases by the discharge if the working liquid contains petroleum, etc. Air is used if the working liquid consists essentially of water. The electric discharge machining may be executed as a primary operation or may be executed as a secondary operation after the surface of the material to be treated is coated with the nonconductive or conductive material as the primary operation.

Title: Electric heater wire
Inventor: SASAKI JUNICHI
IPC: H01B7/28
Filed: 1990-04-03
Abstract: PURPOSE:To prevent snow accretion and ice accretion by winding or twisting Ni-Fe alloy wires with a specific composition on the outermost layer of an overhead electric cable. CONSTITUTION:Ni-Fe alloy wires 3 are wound or twisted on the outermost layer of an overhead cable 2. The composition of the alloy wire is set to Ni 45-80wt.% and the remainder of Fe, and a small quantity of Mn, Cr and Al may be contained additionally. A Zn film, for example, is coated on the surface of the alloy wire to improve water repellency and prevent rusting due to electrolytic corrosion. Alloy wires 3 are spirally pre-formed at the preset pitch. The winding pitch for the overhead cable 2 is selected to 1.5-3 times the diameter of the overhead cable 2. Alloy wires 3 are twisted in outermost element wires 2a of the overhead cable 2, or alloy wires 3 equal to 1/4-1/2 of element wires 2a may be uniformly distributed. Since Ni-Fe alloy wires 3 have large relative magnetic permeability, they generate heat up to the temperature sufficiently melting ice and snow even when the power transmission quantity of the overhead cable is small, magnetic saturation is attained with small magnetic field, thus the heat quantity is small even when the power transmission quantity is large, and no restriction on the power transmission quantity is required.

Title: Pressure detector
Inventor: MORITA SAICHIROU
IPC: G01L9/00
Filed: 1980-06-30
Abstract: PURPOSE:To raise detection sensitivity for high pressure by sealing a non-compressible liquid inside a chamber closed with pressure receiving elements where the same pressure to be measured is given from both directions and by providing an absorbing means for pressure to be applied to it. CONSTITUTION:Pressure P to be measured is applied to pressure receiving elements 10, 11 through a pressure introducing hole 27 on a flange 25 at the side surface of a main body 1. The area of the pressure receiving element 10 is slightly larger than that of the pressure receiving element 11. The pressure receiving elements 10, 11 are composed of bellows, etc., and contracted by external force, thereby permitting a coupling rod 7 to move in the right direction. A moving electrode 14 fixed at the central part of the coupling rod 7 moves in the right direction against a plate spring 12 and pressure P is estimated from changes in electrostatic capacity with respect to the fixed electrodes 17, 18. At the time, a liguid is sealed in the chamber closed by pressure receiving elements 10, 11 and the pressure changes are absorbed by the bellows provided in communication to the upper part. Through this process detection sensitivity of high pressure P is improved.
