Title: Apparatus for measuring inclination of component element
Inventor: TOMAASU SHIYORIAN
IPC: G01C9/06
Filed: 1988-07-22
Abstract: PURPOSE: To obtain an instrument which is improved in optical, mechanical, and thermal stability and can be easily fitted to an apparatus in a reproducible state by coupling optical pass guiding means to each other and to stable carrying plates. CONSTITUTION: A metallic carrying plate 1 joined to the bottom section of a glass carrying plate 1 has holes 10 and 11. The optical path 8 of the light beam emitted from a light source provided in the hole 11 comes into collision with the surface of a liquid 7 in a bell 6 at an angle of about 45 deg. from the bottom side after passing through polarizing prisms 12 and 13, a prism 14, and the transparent plate 1. The light beam is completely reflected by the surface of the liquid 7 and the optical path 8 is led to a position detecting diode in the hole 10 of the plate 9 through the prism 14, polarizing prisms 15 and 16, and a narrow and long prism 17. The means which lead the optical path 8 are firmly coupled with each other and to the stable carrying plates 1 and 9.  The position detecting diode generates two electric signals indicating orthogonal coordinates with respect to the position of the optical path 8 on its receiving surface. Thus the inclination of a component in the direction of gravity is measured.

SOLUTION: A mounting hole 8 for mounting a liquid level detecting device is formed so as to be a vertical cylindrical form by burring on the upper surface of a kerosene reservoir or an oil receiving pan for a fan heater while a liquid level detecting device 9 is fitted into the mounting hole 8 by forcing the same downwardly from the upper part of the hole 8. In this case, a part of the liquid level detecting device 9, which is fitted into the mounting hole 8, is formed so as to be a round rod type small cylindrical unit 10 while projected threads 11, 12, having slightly bigger diameter than the inner diameter of the mounting hole 8, are attached to positions near respective upper and lower ends of the small cylindrical unit 10. According to this method, oil sealing property upon fitting the small cylindrical unit 10 into the mounting hole 8 is secured and coaxial property between the center axis of the small cylindrical part 10 and the center axis of the mounting hole 8 can be increased.

Title: Photo coupler
Inventor: OKABAYASHI NAONORI
IPC: H01L31/12
Filed: 1984-08-29
Abstract: PURPOSE:To obtain a photo coupler capable of responding at a high sensitivity and a high speed by a method wherein a photo diode is provided in the vicinity of the side surface of the light-emitting element of the light-receiving element chip separately from the photo diode for signal detection of the chip. CONSTITUTION:An N-type epitaxial layer 6 is provided on the periphery of a P type substrate 1, a photo diode 9 consisting of the substrate 1, a P<+> type isolation layer 3 and the N-type epitaxial layer 6 is constituted separately from a photo diode 8 for signal detection consisting of the substrate 1 and an N-type epitaxial layer 2, and the effect due to the propagation component of light to inside from the front of the chip is prevented with a metal film 7. The anode and cathode of an element 9 are earthed. That grounding can do so long as the N<+> type emitter diffusion layer and the earthed wiring are connected. In this constitution, since the effect due to the propagation component of light to inside from the front of the chip is prevented with the metal film 7 and the light to inside from the side surfaces is absorbed by the photo diode 9, the effect to exert the diode 8 for signal detection is eliminated. As a result, the photo coupler capable of responding at a high sensitivity and a high speed is obtained.
