Title: Production of metal powder of pseudo-spherical irregular shape
Inventor: TAKADA AKIHIRO
IPC: C22C38/34
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To obviate the necessity of a crushing stage and to obtain a magnetic metal powder combining magnetic properties, corrosion resistance, and wear resistance by using, as an atomization gas for gas atomization, a gaseous mixture of inert gas and oxygen in specific volume ratio. SOLUTION: As an atomization gas at the time of gas atomization, a gaseous mixture consisting of, by volume ratio 70-99% inert gas and 1-30% oxygen is used. A material for the metal powder to be produced has a composition consisting, e.g. of, by weight ratio, 0-10% Si, 5-25% Cr, 0-5% Mo, 0-10% Al, 0-5% Ti, and the balance Fe with inevitable impurities. As the inert gas in the gaseous mixture, one or more kinds among argon, nitrogen, and helium are used. It is preferable that the metal powder of pseudo-spherical irregular shape obtained by gas atomization has an aspect ratio ranging from 1.5 to 6. By mixing a prescribed quantity of oxygen with the inert gas, oxides are formed on the surface of a molten metal and surface tension is reduced and the resultant solidified powder shows pseudo-spherical shape.

Title: Preparation of caustic alkali
Inventor: ODA YOSHIO
IPC: C25B1/46
Filed: 1979-11-09
Abstract: PURPOSE:To stably manufacture high concentration caustic alkali with high electric current efficiency, by introducing the aqueous solution of alkali chloride into the anode room partitioned by the gas closely stuck to the cation exchange membrane and liquid permeable anode and then electrolyzing by using the oxygen reduction cathode. CONSTITUTION:An electrolytic bath 1 is divided into an anode room 4 and cathode room 5 by a cation exchange membrane 3 closely stuck the gas and liquid permeable anode 2 to the one side. Said room 5 is divided into two rooms by a gas permeable cathode 6 and the gas-containing oxygen is flowed through an inlet 13 and outlet 14 of an oxygen-containing gas supply room 7. Aqueous solution of alkali chloride is supplied from an introducing opening 9 into the room 4 and is flowed out from an outflow opening 10. Further, water is supplied from a supply opening 11 into a cathode solution producing room 8 and produced aqueous solution of caustic alkali is flowed out from an outlet 12. On occasion of electrolyzing the aqueous solution of alkali chloride by applying a direct current voltage, hydroxyl radical is produced by reacting oxygen gas diffused in the cathode 6 with a nascent state hydrogen produced in the cathode 6. Accordingly, electrolytic voltage is lowered because of no-generation of hydrogen gas.

Filed: 1985-07-01
Abstract: PURPOSE:To avoid distrotion of a video signal by connecting a clamping circuit and a clip circuit, with an output of amplifier and also applying negative feedback from an output of the clip circuits to obtain clip characteristics of flat, constant level. CONSTITUTION:A video signal which is inputted from an input terminal 1 is inputted to an amplifier 6 from a non-inversion input and enter in an input of modulation circuit 4 as well as an inversion input of the amplifier 6 through the clamping and clip circuit 3. When signal level is less than clip level, the circuit 3 operates as a whole feedback amplifier and output signal which is faithful to input signal is obtained. When the input signal signal level of which is more than the clip level, are inputted the clip circuit operates and then the circuit 3 outputs the output signal where signal more than the clip level is compressed for the input signal. The amplifier 6 operates with a full gain so as to conform the compressed signal to the input signal and more compresses said signal. Thus, more flat, constant level is obtained at the clip level as an output.

Title: Microjoint structure
Inventor: KAJIWARA RYOICHI
IPC: H05K3/34
Filed: 1987-06-12
Abstract: PURPOSE:To eliminate the destruction of a bonded part and to enhance its fatigue life by a method wherein this bonded part is constituted by a thin metal wire and a brazing material which has bonded each end of the thin metal wire to a connection terminal part. CONSTITUTION:A material 1 to be bonded and a material 1' to be bonded are coupled by using a microjoint structure which is composed of the following: a connection terminal part 2 installed at the material 1 to be bonded; a connection terminal part 3 installed at the material 1' to be bonded; thin metal wires 6 installed at a gap between the mutually facing connection terminal parts 2, 3; brazing materials 4, 5 bonding individual ends of the thin metal wires to the respective connection terminal parts 2, 3. If a relative dislocation delta is caused between the material 1 to be bonded and the material 1' to be bonded due to a change in a temperature, the relative dislocation delta is absorbed by a bending deformation of the thin metal wires 6; accordingly, a shearing stress caused at the thin metal wires 6 and the brazing materials 4, 5 is remarkably low. By this setup, a bonded layer is not destroyed and a fatigue life can be enhanced.

Abstract: PROBLEM TO BE SOLVED: To prevent the falling of a weld bolt off a coupling flange. SOLUTION: In fixing a weld bolt 5 to a coupling flange 4, the used bolt 5 is provided with projections 5c on the underside of a head 5b and a neck 5d thinner than the outer diameter of a threaded portion 5a, and the coupling flange 4 is formed through the burring process with a bolt insertion hole 11 having a burring part 11a with its hole diameter being larger than, and equal to or smaller than the outer diameter of the threaded portion 5a before being fixed and after being made flat respectively. The projections 5c are then melted through the resistance welding to fix the weld bolt 5 on the coupling flange 4 as well as make the burring part 11a flat. As a result even if the threaded portion 5a of the weld bolt 5 hits against another object to result in the peeling of the welding, the threaded portion 5a is prevented from falling off the bolt insertion hole 11.
