Title: Refining heat treatment for medium carbon martensite stainless steel
Inventor: KINOSHITA NOBORU
IPC: C21D1/84
Filed: 1980-12-08
Abstract: PURPOSE: To maintain strength and hardness without lowering rust resisting property by applying refining heat treatment under a specified condition after austenitizing a part of texture of medium carbon martensite stainless steel.  
     CONSTITUTION: The ≥60% texture of a hot-rolled annealed steel plate of martensite stainless steel containing 0.20W0.40% C, 12.0W18.0% Cr is austenitized by holding it at 1,000°C for 5min. From this temperature to a temperature range of 900W700°C, it is cooled at a cooling rate of 20W300°C/min. Then, it is quenched by oil hardening from that temperature. By this way, hardness and tenacity characteristics similar to the case of conventional refining heat treatment can be obtained by one treatment at low cost without lowering the rust resisting property.

Title: Horizontal leading device for tone arm
Inventor: SOGA AKIRA
IPC: G11B3/085
Filed: 1979-12-29
Abstract: PURPOSE: To execute the leading operation of a tone arm rapidly and accurately by detecting the operation time of a switch for commanding horizontal operation and by performing the leading operation at a low speed up to a prescribed time and at a high speed after the prescribed time.  
     CONSTITUTION: For example, horizontal drive control circuit 20 supplying a driving current to horizontal driving motor 40' for horizontal leading operation of tone arm 100' is constituted as shown in the figure. When timer 11A is put into operation through the operation of lead-in switch 13' and continues to operate continuously for longer than a prescribed time, a control signal which switching change-over circuit 11' is outputted after the prescribed time to change low-speed driving circuit 20A over to high-speed driving circuit 20B. Thus, when the tone arm is led by a small distance, the tone arm is accurately stopped and the leading operation time for long-distance can be shortened.

Filed: 1992-06-30
Abstract: PURPOSE:To improve various characteristics of battery, particularly, oxygen gas absorbing characteristic by containing a hydrogen storage alloy particle having a large particle size in hydrogen alloy particles of an electrode in which a conductive core body and the alloy particle, and the alloy particles are mutually fixed by a binder, respectively. CONSTITUTION:A hydrogen storage alloy 2 having a large particle size and a hydrogen storage alloy 1 having a small particle size are mixed together in a mixing ratio of 5:95, and a water-soluble polymer is added thereto as a binder 3 followed by kneading to prepare a paste. The paste is applied to both surfaces of a collector body consisting of a punched metal followed by drying to form a hydrogen storage alloy electrode. Since the film thickness of the binder adhered to the surface of the particle the large particle size is thinner than that in the one having the small particle size, the binder is dissolved by an electrolyte when this electrode is used for a battery, and the thinned part is easily exposed. Thus, binder removing effect is more remarkably exhibited, and various characteristics of battery, particularly, oxygen gas absorbing characteristic is improved.

The oscillating frequency of the oscillator 6 is again shifted in an amount corresponding to the resolution through PLL control. Repetition of this motion should provide a detuning characteristic with high resolution.
