IPC: H01F27/32
Filed: 1985-03-29
Abstract: PURPOSE:To stop the progress of the electric discharge on the impulse part generated by the minute oil gap located between coils and an intercoil spacer by a method wherein the width of a vertical duct is made wider than the width of the intercoil spacer. CONSTITUTION:A vertical groove 5, having the base larger than the aperture part, is formed by a vertical duct piece 2. A protrusion is provided on an interlayer spacer 3 in such a manner that the spacer is fitted in the vertical groove 5 and that the spacer is moved vertical duct piece 2 is constituted in such a manner that it is made wider than the width WS of the intercoil spacer 3. Partial electric discharge is generated from the wedge-shaped microscopic oil gap located between the spacer 3 and the innermost coil of a disc coil, and said electric discharge progresses on the creeping surface of the spacer 3 toward the inner side. However, as the width WV of the duct piece 2 is wider than the width WS of the spacer 3, the progress of the electric discharge is stopped on the surface of the vertical duct. Through these procedures, the dielectric strength between the main insulating members can be improved.

Title: Optical disk reader
Inventor: KOKADO HIROSHI
IPC: G11B7/135
Filed: 1990-03-16
Abstract: PURPOSE:To reduce the number of parts and to realize an optical disk reader which can be miniaturized by making one surface of a lens whose focal distance becomes negative plane and using it as a beam splitter. CONSTITUTION:A luminous flux emitted from a light source S is transmitted through a diffraction grating 1 and reflected on the plane of a negative lens 2. Then, it is focused on the information recording surface of an optical disk medium 4 through an objective lens 3 and diffracted according to the existence of information (a pit). Besides, after the light intensity thereof is modulated, it is made incident on the plane of the lens 2 again through the lens 3. Since the luminous flux is transmitted through the plane at a fixed rate, it receives the action of the lens 2. As the result, the diameter of a condensing spot at a signal detection point P is magnified and the allowable degree of positional accuracy is expanded. The diffraction grating 1 is necessary when a track following system on an optical disk is made a 3 beams system and it is unnecessary in the case of one beam system.

Title: Method and device for controlling exhaust pressure of radiant tube
Inventor: MIYAKE SHUNEI
IPC: F23N3/06
Filed: 1990-03-15
Abstract: PURPOSE:To provide a combustion exhaust pressure control having good controllability with a device of comparatively low cost by controlling the opening of a damper provided at each zone of a combustion control system so that exhaust pressure reaches a target pressure and also controlling the opening in a noninteracting manner in which pressure control in each zone does not interfere with each other. CONSTITUTION:In radiant tubes 2 provided in a furnace body 1 of an indirect heating furnace, exhaust gas pressure is detected in each combustion control system to control pressure in each zone by controlling the opening of dampers 22A, 22B based on the detected pressure. When exhaust pressure is controlled, control gain varies when the opening of damper changes and hence the control gain is corrected corresponding to the opening of damper by means of a variable gain setting unit 13 and also a noninteracting control is performed by means of a noninteracting control operation unit 14 to prevent interference in pressure control due to differences in the opening of damper between exhaust ducts. In the unit 14, a noninteracting control by pseudo- diagonal method is employed for the exhaust pressure control of radiant tube. As a result, combustion at the radiant tube is stabilized and damage to equipment due to backfire of burner etc., can be avoided.
