Filed: 1991-05-27
Abstract: PURPOSE:To mount a photoelectric converter in a high positional accuracy by forming a fusion-bonding metal thin film on the converter or a board in which the converter is formed. CONSTITUTION:Photodiodes 105A, 105B, 105C, 105D to become photoelectcic converters are so formed that the photodiodes 105A, 105B are on a board 106A and the photodiodes 105C, 105D are on a board 106B. An In film 107 is formed as a fusion-bonding metal thin film on its rear surface. Thus, fusion-bonding metal is not melted by heating in the case of submounting or die bonding of a semiconductor laser. Since it can be fusion-bonded in a thickness of several mum, its positional accuracy is raised, and necessity of mounting while confirming the accuracy of an optical axis direction at the time of mounting is eliminated to be simple.

Title: Oxygen concentrator
Inventor: IWAKAME MAKOTO
IPC: C01B13/02
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by enabling a compressor to be operated on a low load by a method wherein, in the case where an output amount of a product gas is small, feed of an air to an adsorption room is once stopped and, at the same time, a pressure in the compressor is reduced by a pressure reducing means. SOLUTION: A compressor 1 feeds air to a first adsorption cylinder 2 and a second adsorption cylinder 3 by being driven with a motor. A compressor exhaust valve 11 is connected to the compressor 1, and releases the air in the compressor 1 outside. By being equipped with the compressor 1 and the air is exhausted outside during operation of the compressor 1, the compressor 1 can be operated on a low load. For example, in a small flow rate of a product gas, an inlet valve 6, an exhaust valve 8 and a compressor exhaust valve 11 are opened, and the other valves are closed. Thereby, the feed of the air to the first adsorption cylinder 2 is stopped, and simultaneously the pressure in the compressor 1 is reduced. Consequently, the compressor 1 comes to be operated on the low load, and a significant reduction of power consumption can be attained.

Title: Method and apparatus for detecting position of moving machine
Inventor: KOYAMA MORIO
IPC: G01B11/00
Filed: 1989-05-17
Abstract: PURPOSE:To simplify the constitution of an apparatus by incorporating rubber optical cable into cabtire cable, winding and unwinding the cabtire cable around and out of a reel, and detecting the position of a moving machine from the change in amount of light which is generated by the winding and the unwinding. CONSTITUTION:Rubber optical cable is incorporated in the central part of cabtire cable 10. Light is transmitted through the optical cable from a light source 13. A moving machine 1 is advanced, and the cable 10 is unwound out of a reel 2. Thus the cable is made to be approximately straight line. An input signal (x) which is inputted into a photodetector 14 at this time is detected. Then the moving machine 1 is moved backward, and the cable 10 is wound around the reel 2. Under this state, an input signal (y) which is inputted into the photodetector 14 is detected. The wound length of the cable 10 around the reel 2 is proportional to the attenuating amount of the light. The wound length of the cable 10 is proportional to the running distance of the moving machine 1. Therefore, when the signals (x) and (y) which are inputted into the photodetector 14 are obtained beforehand, the wound length of the cable 10, i.e. the running distance of the moving machine 1, can be obtained based on the input signals in the photodetector 1 during the period, and the position of the moving machine 1 can be detected.

Title: Sunbeam automatic tracking and focusing device
Inventor: YOSHIMURA MASAO
IPC: F24S10/70
Filed: 1978-10-04
Abstract: PURPOSE: To absorb and convert solar energy at high efficiency by automatically tracking sunbeams through a hemispherical convex lens and focusing onto an absorber movingly.  
     CONSTITUTION: The hemispherical convex lens 1 for a sunbeam focusing device consists of an optical glass. Spheres of the lens 1 and an absorber 4 are arranged to come on a concentrical circle to form a sphericity so that the absorber 4 is same diameter and concentric as the lens 1 to allow the focus to concentrate on the absorber 4. Where direct rays of the sun are incident through the hemispherical convex lens 1, the focus concentrates on the absorber 4 given on the diameter of the lens 1. The direct rays of the sun are then incident through the lens 1 movingly through automatic tracking, and thus the focus concentrates movingly on the absorber 4 coming on the diameter of the lens 1. The automatic tracking is then repeated endlessly.
