    摘要： Silicon carbide particles are produced by reacting a gaseous silicon compound or granular silicon with a carbon compound at a high temperature. In the reaction, the amount of free carbon content in the resultant silicon carbide particles can be controlled by monitoring the amount of unsaturated hydrocarbon such as acetylene, as a by-product. Moreover, silicon carbide particles can contain boron dispersed uniformly in the particles by a two step process comprising first reacting a silicon source and a boron source without a carbon source in a first reaction zone, to form boron-containing silicon particles, and second, reacting the resultant particles with a carbon source in a second reaction zone. Further, the above-mentioned monitoring of an unsaturated hydrocarbon by-product allows the obtaining of silicon carbide particles containing no free carbon, and the silicon carbide particles containing boron in the particles but no free carbon may be sintered without the addition of free carbon, to give a dense sinter.

    摘要： A solenoid valve includes: a moving core; a coil for generating magnetic force that attracts the moving core; a stator that forms a magnetic circuit in cooperation with the moving core and attracts the moving core; and a cup-shaped member disposed at the inner periphery of the stator and on the outer periphery of the moving core. The cup-shaped member reciprocatably supports the moving core, and restricts hydraulic fluid leakage from the moving core side to the outer periphery side. A collar made of a soft magnetic material, disposed so as to face a face on the stator side in the axial direction of the moving core, and forming a magnetic circuit in cooperation with the moving core and the stator.

    摘要： A bottomed cylindrical member is disposed inner side of a stator core and a coil. The cylindrical member is made of non-magnetic material such as a stainless steel. The cylindrical member has a small diameter portion at the bottom side and a large diameter portion continuously made with the small diameter portion at the side of an attracting portion and has a larger inner diameter than that of the small diameter portion. The small diameter portion is slidablly in contact with a slider core, and reciprocatably supports the slider core. Since a radius difference between the small diameter portion and the large diameter portion is equal to or larger than 30 μm, a clearance larger than sliding clearance is formed between an inner circumferential surface of the large diameter portion and an outer circumferential surface of the sliding core. Thus, an electromagnetic driving apparatus and an electromagnetic valve, which smoothly reciprocate the sliding core, are provided.

    摘要： A shaft is press-fit into the valve member or the plunger of an electromagnetic valve to transmit the axial movement of the plunger to the valve member. A diameter reducing mechanism is provided for reducing the diameter of at least the press-fit portion of the shaft so that the diameter of the shaft is decreased by a press-fitting force applied to the shaft by the valve member and/or plunger. Deformation due to the press-fitting process is absorbed by the shaft, so deformation of the valve member and/or plunger is inhibited. Accordingly, it is unnecessary to give a large margin to a plunger side air gap, and magnetic efficiency can be improved. Also, two chambers on both axial sides of the plunger can communicate with each other through a clearance provided by the C-shaped cross-section, an inner hole and a penetration hole of the shaft. Therefore, it is unnecessary to form any separate groove or hole in the plunger for respiration.
