Title: Recording and reproducing circuit
Inventor: SHIROGANE TATSUO
IPC: H03F3/181
Filed: 1983-10-11
Abstract: PURPOSE:To attain the accurate switching between the record and the reproduction with a simple constitution of circuit which can be easily converted into monolithic integration, by obtaining easily the frequency characteristics of a record mode as well as the resonance characteristics of a reproduction mode. CONSTITUTION:In a record mode the emitter of a transistor (TR) Q22 is grounded with the collector connected to and end of a winding 32a of a rotary transformer 32. The other end of the winding 32a is connected to the base of a TRQ23 via a capacitor 34 and receives no effect of the capacity of a circuit at the reproduction side. In a reproduction mode the TRQ22 is used for both a switching TR and a constant current output TR. Thus the use of a bypass capacitor is eliminated and the structure of a changeover switch is simplified. In this way, a recording/reproducing circuit and a switching circuit of a VRT can be converted with high efficiency into a monolithic IC which works at a low level of voltage. The deterioration of frequency characteristics is avoided in a record mode. Furthermore it is possible to obtain easily the desired resonance frequency characteristics without being influenced by the recording circuit side.

IPC: C25D11/18
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To improve the adhesion property to a sealing resin by executing a heat treatment at a prescribed temp. after a sealing treatment. SOLUTION: An anodically oxidized film 8 of the heat sink 1 is formed by an anodic electrolytic treatment and fine pores extending perpendicularly exist on the surface of this film 8.

Title: Production of fused flux for submerged arc welding
Inventor: KONISHI TOSHIO
IPC: B23K35/40
Filed: 1983-10-11
Abstract: PURPOSE:To improve productivity of a flux by allowing a fused flux to flow downward by gravity and spraying gaseous material to the descending flow thereby solidifying the flux by air cooling to a powder and granular state while the fused flux flies in the form of particles. CONSTITUTION:Various conditions for production are set as follows in the stage of obtaining a flux F having an adequate grain size: The viscosity of a fused flux M is first set at <=10 poise. If the viscosity is higher than 10 poises, the flux flies like stringing to form fibrous fluxes which require regrinding. The flow rate of gas is set at 20-100m/sec. If the flow rate is <20m/sec., the flux does not fly and the lumped fluxes deposite in the falling position. If the flow rate exceeds 100m/sec., the flux is drifted to assume the fibrous state without flocculation. With flow rate molten metal amt. is regulated at 0.37-2.8m<3>/kg. If the wind flow rate for each 1kg of the molten metal is below 0.37, the particles are fused to each other again into a lump state. On the other hand, if the wind flow exceeds 2.8m<3>, cooling is excessive and the driving power of a blower 2 is wastefully consumed. An angle theta of injection is set at + or -40 deg. when viewed from a horizontal direction. If the angle exceeds +40 deg., the flux F scatters and is difficult to be recovered. If below -40 deg., substantial air cooling effect is not obtainable.
