Filed: 1988-05-16
Abstract: PURPOSE:To have an arbitrary gap length in which joining is sure, strong and comparatively large by forming a gap regulating film only at the joining surface of either of the joining surfaces formed respectively at a core half body. CONSTITUTION:In a magnetic head joined by a glass 5 by butting two core half bodies 1A and 1B through a gap regulating film 7 of a prescribed thickness, a gap regulating film 7 is formed only on one side joining surface out of the joining surfaces formed respectively to two core half bodies 1A and 1B by the butting surface and the glass 5.

Title: Semiconductor device
Inventor: KONISHI YUZURU
IPC: H01L25/10
Filed: 1977-09-28
Abstract: PURPOSE: To prevent secondary hazards by providing insulation tubes around metal electrodes to encircle the element and forming gaps with the tubes, element and electrodes.  
     CONSTITUTION: Explosion-proof rings 10, 11 of ceramics are brazed to metal blocks 1, 2. When extremely large energy is produced from Si plate 7, the energy advances straight forward and hits against the explosion ring 11. The rign 11 then evaporates to absord the energy and cools the high termperature, thus preventing the fusion of the metal plate 4. When a support plate 4 fused, the energy hits against the explosing ring 10, by which the arc energy is attenuated and the fusing of the metal thin plate 3 is prevented

Abstract: PURPOSE:To take measures to meet the overload to avoid harmful voltage drop by taking load voltage into an adder, by inputting the result added by a load a voltage command value through an absolute value circuit and by outputting an output signal available for the step to meet the overload as compared with the maximum value of voltage variation allowance of the load. CONSTITUTION:Load voltage VL of a power converter 1 is detected and inputted into an adder 101, with which the voltage variation portion VL to the load voltage command value VL* is found. The voltage variation portion  VL is then inputted into an absolute value circuit 102, where the absolute value ¦ VL¦ of the voltage variation portion VL is found and inputted into a comparator 103. In the comparator 103, the absolute value ¦ VL¦ is compared with the maximum value VLmax of voltage variation portion  VL which the load can permit. The instantaneous drop of the output voltage due to the instantaneous overload, inrush of a transformer, etc., can thereby be detected quickly, so that a control step can be taken before the load is adversely affected.
