Title: Production of optical isolator
Inventor: OSAWA RYUJI
IPC: G02B27/28
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To a process for production which improves the yield of a high- reliability optical isolator by applying a water repellent surface reforming agent to the surface of an optical material consisting of a polarizer, Faraday rotator and analyzer after the end of joining this optical material by soldering, then cutting the optical material. SOLUTION: Two to three layers of the thin films of the materials varying in refractive index are usually formed as the antireflection films formed on the surface of the optical material. Among these films, the materials frequently used as the material to be formed on the extremely surface are SiO2 , TiO2 and Al2 O3 films which have high surface energy, are extremely active and react to adhere securely to dust, such as chips, fur and wax. Then, the water repellent surface reforming agent is applied on the surface of the antireflection films, by which the surface energy is lowered and the contact angle of cooling water on wax with the surface reforming agent is increased. The infiltration of the cooling water or wax into the spacings is thus prevented. Further, the chips, if infiltrated, are removed by simple washing without secure sticking.

Title: Force control unit and force control robot
Inventor: JINNO MAKOTO
IPC: B25J13/08
Filed: 1990-10-09
Abstract: PURPOSE:To easily erase gravity and inertia force and to detect a correct pressing force onto the member to be worked of a terminal effector, by moving the detection position of a detection means to the center of gravity of the terminal effector, finding the moment around this center of gravity, and operating the pressing force to the member to be worked of the terminal effector. CONSTITUTION:In the case of a pressing force to the member to be worked of a terminal effector (grinder) 5 being taken as F, the pressing force is calculated by a force control unit 19 with the use of the moment MG around the center of gravity of the terminal effector 5 detected by a detection means 11, and a vertical distance (r) from the center of gravity. Also even in the case of an inertia force being exerted on the terminal effector 5, i.e., even in the case of acceleration alpha being caused in the pressing direction of the terminal effector 5, in order to control the pressing force, the inertial force malpha [(m) is the weight of the terminal effector 5] caused thereby is not detected at all on the moment MG around the center of gravity. Therefore a correct pressing force can be detected without receiving the effect of an inertial force, etc.

IPC: H04N5/225
Filed: 1992-09-11
Abstract: PURPOSE:To perform the foggy picture tone display with operations of a fade key and a foggy key of a camera. CONSTITUTION:When a fade key 11 is pushed in a photographing mode of a camera 10, a feature controller 5 carries out the PWM control of a FADE signal in a fade mode.

Title: Preparation of particle board
Inventor: HAYATA YASUNARI
IPC: B27N1/00
Filed: 1985-11-30
Abstract: PURPOSE:To obtain a particle board having perfect water and humidity resistance by heating chips in a specified incombustible gas atmosphere and at a specified temp. and by removing thereby completely water and liquid in the resin. CONSTITUTION:Chips are put in a tank for treating and heating and the air in the tank is evacuated to make an atmosphere of more than 95% incombustible gas in the tank. By heating and keeping the temp. in the tank at an elevated temp. between 100 and 200 deg.C, water and liquid in the chips in the tank are completely removed. As fibrous structures only thereby remain, an adhesive penetrates into the inner system of the vessels and the bonding strength between chips becomes larger. The mixture of the chips with the adhesive is molded into a plate and then treated by hot pressing, cutting in a specified dimension and polishing to complete a particle board.

Filed: 1993-10-28
Abstract: PURPOSE:To make tertiary winding of a saturable current transformer unnecessary and lower the cost and the loss by connecting a specified saturation time controlling circuit to a secondary coil in one side of the saturable current transformer. CONSTITUTION:Regarding a saturation time controlling circuit 21, an impedance component is composed of an impedance variable circuit 25 which is a series circuit of resistors 22, 23 and an FET 24. The output in the secondary side of a saturable current transformer 4, that is, the output of the secondary winding 14, is voltage-doubled and rectified by a voltage doubling and rectifying circuit 30, smoothed by a smoothing capacitor 31, and then sent to a variable circuit 25 and thus the flowing current level alters. Consequently, the saturation time of the transformer 4 also alters and the operation of the inverter circuit 1 is controlled automatically. Without a tertiary winding being set in the transformer 4, operation control can be done by self-excitation type inverter circuit. As a result, the cost and the loss of the transformer 4 are lowered.

Abstract: PURPOSE:To smooth a starting at low illuminance by a method wherein a condensing body to store a minimum electromotive force is connected in parallel to a solar battery for feeding a current to an electric motor through a switch body, and by detecting that the condensing body is charged with electricity, the switch body is brought into an energizing state. CONSTITUTION:In the morning in which a solar radiation amount is low and illuminance is low, an output from a solar battery 11 is not increased to a power enough high to allow the starting of an electric motor 14 of a blast fan 16. Thereby, a transistor 13 serving as a switch body is brought into an non-energizing state and a capacitor (condensing body) 12 is charged with an output from the solar battery 11. When it is detected by a control part 15 that voltages at both ends of the condensing body 12 exceed a minimum starting power, the switch body 13 is energized, an output from the condensing body 12 is applied togetherwith the output from the solar battery 11, and the electric motor 14 is smoothly started. Since regarding a power after the electric motor 14 is started, there is no need for a high power, drive can be maintained by means of an output from the solar battery 11.
