Title: Semiconductor light emitting and receiving device
Inventor: YOSHIDA JUNICHI
IPC: H01L31/10
Filed: 1985-03-08
Abstract: PURPOSE:To make it possible to transmit and receive light beams having different wavelengths simultaneously by one piece of optical fiber and one light coupling path without noise and to avoid a large configuration and a high cost, by coupling the two light emitting and receiving devices, in which first - third semiconductor light emitting and receiving elements are arranged, by optical fiber, and shorting the electrode of one light emitting and receiving element and a common electrode. CONSTITUTION:The wavelength of light beams L1-L3, which can be emitted or received by first - third semiconductor light emitting and receiving elements are made to have relationship of lambda1<l2<lambda3. Two semiconductor light emitting and receiving devices are used as U1 and U2. The U1 and U2 are coupled by one piece of transmitting and receiving optical fiber. Therefore, two light coupling paths are not required for the optical fiber for transmission and reception, and only one path is enough. When the light L1 is emitted by the first light emitting and receiving element M1 and the light L3 is simultaneously received by the third light receiving element M3, an electrode E2 of the second light emitting and receiving element M2 and an electrode E0 are shorted. Thus light emission and light reception can be performed without substantially accompanying noises.

Abstract: PURPOSE:To make easy automatic assembling and make less eddy current by inserting a core into the center hole of a bobbin providing the primary and secondary coil and by winding the magnetic belt material at the circumference of the bobbin so that the both end surfaces of core are opposed. CONSTITUTION:An internal magnetic core 3 is inserted into the center hole of bobbin 2 providing the primary and secondary coil 1. The internal magnetic core 3 can be formed by laminating belt type ribbons such as permalloy or silicon steel plate and then baking it into a squarepillared shape. Both end surfaces of it are alined by the polishing and are extruded a little from the bobbin 2. Both external side surfaces of bobbin 2 are integrated with the winding guide frames 4, 4. The belt type ribbon 5 consisting of the same material as the internal magnetic core 3 is wound around the circumference of the bobbin 2 for the predetermined number of turns with said guide frame used as the guide. This belt type ribbon 5 becomes the external magnetic core and forms a closed magnetic circuit in cooperation with the internal magnetic core 3.

Right thereafter, a solenoid valve 19 is opened and closed at a cycle of 3-7 seconds for a specified time, compressed air is intermittently injected, and the flow of lubricating oil is returned to its initial high velocity of flow. Through repetition of the aboves, pulsation is forced to occur in a piping, and a foreign matter in the recessed part of a piping can be caused to effectively flow to the outside.

Title: Fitting structure of guide vane stem in water turbine
Inventor: OONAKA HIROSHI
IPC: F03B3/18
Filed: 1981-03-31
Abstract: PURPOSE:To protect the outer surface of a guide vane stem from damages, by fitting the guide vane stem in a unitary manner by interposing a torque transmitting means between the guide vane stem and the control lever of a water turbine. CONSTITUTION:When compressive force is applied by a torque transmitting means 3, a sleeve 11 is compressed into the form of a sleeve 11' and the gap A at the split part of the sleeve 11 is reduced. However, since some gap still remains at the split part of the sleeve 11', it is held in uniform contact with the entire outer surface of a guide vane stem 4, so that the pressure acted to the contact surface S1' is also rendered uniform. Therefore, if an excessive torque is acted to the guide vane stem 4 and slippage is caused at the contact surface S1', scuffing is not caused on the inner surface of the sleeve 11' and the outer surface of the guide vane stem 4.

Title: Polishing tape
Inventor: YAMAGUCHI NOBUTAKA
IPC: G11B5/187
Filed: 1986-03-04
Abstract: PURPOSE:To enable precision polishing without damaging a polished surface, even if a polishing agent of high Mohs' hardness is mixed, by mingling the binder of a polishing applied film with a copolymer made from vinyl chloride and vinyl acetate and having a hydroxyl group and a carboxyl group in each molecule. CONSTITUTION:A polishing applied film 2 is slid on the tape sliding surface of a magnetic head 3 to smoothly polish the tape sliding surface by a polishing agent of hard grains projecting from the surface of the applied film 2. The diameter of the grains of the polishing agent is adjusted depending on the purpose of use thereof. The polishing agent, a binder and additives including a lubricant and so forth are mingled together to make the polishing applied film 2. A copolymer made from vinyl chloride and vinyl acetate is mixed with polyester polyol or the like to make the binder. The copolymer has a hydroxyl group and a carboxyl group in each molecule. The hydroxyl group acts to uniformly disperse the polishing agent. The carboxyl group acts to heighten the adhesive power between the binder and the polishing agent. As a result, uniform polishing is enabled. The polishing agent of high Mohs' hardness can thus be used.
