Title: Treating method of magnetic powder
Inventor: KITAHATA SHINICHI
IPC: G11B5/706
Filed: 1990-10-20
Abstract: PURPOSE:To make it possible to attain excellent conductivity and a superior magnetic characteristic by applying carbon on the surface of a particle of ferrite powder by subjecting platelike hexagonal system crystal ferrite powder to heat treatment in a carbonic acid gas flow after it is subjected to heat treatment in a hydrogen gas flow. CONSTITUTION:After platelike hexagonal system crystal ferrite powder is subjected to heat treatment for 1 to 6 hours at a temperature of 100 to 450 deg.C in a hydrogen gas flow, it is subjected further to heat treatment for 1 to 6 hours at a temperature of 50 to 350 deg.C in a carbonic acid gas flow, so that carbon of 2 to 20wt.% to the ferrite powder be applied on the surface of a particle of the powder. According to this method, a surface layer of the hexagonal plate crystal ferrite particle is reduced by the heat treatment in the hydrogen flow, a carbonic acid gas is decomposed on a surface part of the ferrite particle by the subsequent heat treatment in the carbonic acid gas flow and the carbon is connected uniformly on this surface of the particle. Thereby the powder is made excellent in conductivity and a change in the characteristic with time is prevented substantially.

Title: Burner device
Inventor: KANEKO HIDEKI
IPC: F23N5/00
Filed: 1985-12-17
Abstract: PURPOSE:To provide a low NOx content, improve a responsive characteristic of an air ratio control and detect a back-fire by a method wherein a thermocouple is arranged at a bottom part of flame hole portion of a burner and a damper having driving mechanism is arranged at an air suction passage including a fan motor. CONSTITUTION:A thermocouple 14 is arranged at a bottom part of flame hole portion 10, a damper 19 driven by a motor 18 is installed at a suction port, and both a discharge port and a mixture chamber 11 of a burner 9 are connected by a mixing pipe 20. Flame temperature is detected by the thermocouple 14 and its value is outputted to a circuit 24. An air ratio enables a high first combustion to be performed with a combustion fan motor 17, resulting in that a combustion temperature can be decreased and further an amount of production of NOx can be restricted. When a difference between the combustion temperature and a set value exceeds a specified range, the motor 18 is controlled and a degree of opening of the damper 19 is varied. Since the damper has a lower inertia moment than that of the fan, its responsive speed is high. When a back-fire occurs, a cold contact point 16 of the thermocouple 14 placed adjacent to the mixture room 11 is heated and an electromotive force of the thermocouple 14 is decreased less than that at normal time, so that the back-fire can be detected.

Abstract: PROBLEM TO BE SOLVED: To easily and correctly perform relative adjustment of driven wheels in a small required area by allowing the driven wheels to be relatively fixed to each other by a hydrodynamic pressurizer and by causing the pressurizer to be canceled in activation by a cancel unit. SOLUTION: Pressurizing force is applied to a piston 17 through a collar 18 of a spring 19 whereby pressure oil in a pressure fluid path 23 is pressurized. The pressure also occurs in an annular chamber 29 through a radial direction hole 23a, an annular flow path 27 and a coupling path 28, whereby a film 30 presses a shaft 11 and a sprocket 15 is held on the shaft and rotates with the shaft. To change a relative positional relation between sprockets 13, 15, a lock pin 16 is first inserted into a hole 15a of the sprocket 15 and it is held in position. The piston 17 is displaced to the right against force of the spring 19 to lower pressure in the pressure fluid path 23 and the annular chamber 29, thereby accordingly canceling pressurization between the film 30 and an external face of the shaft 11.
