Abstract: PURPOSE:To make it possible to manufacture powder of a rare earth magnet having excellent oxidation resistance at a low cost by mixing a surface treating agent for preventing oxidation of the magnet powder into solution wherein rare-earth magnet alloy undergoes wet crushing, and forming an excellent resin film on the fine powder of the rare earth magnet by a simple treating method. CONSTITUTION:In the manufacturing method of the powder of a rare earth magnet, surface treating agent for preventing the oxidation of the magnet powder is mixed into solution wherein the rare-earth magnet alloy undergoes wet crushing. For example, alloy lump for 200g of Nd-Fe-B-based magnet is coarsely crushed with a hammer. The powder is placed into a pot for a ball mill together with balls made of superhard alloy. Meanwhile 600g of 4wt.% solution wherein powder-state polyacrylonitrile is dissolved into N.N-dimethylformamide is put into the pot. The air in the pot is evacuated with a vacuum pump. The pot is set in the rotary ball mill. The material is crushed for 8 hours and the fine powder whose average particle diameter is 5mum is obtained. After the supernatant in the ball mill pot is removed, the powder is stirred, and the pressure is reduced. Thus the N.N-dimethylformamide is removed. The neodymium magnet powder whose surface is coated with the polyacrylonitrile is obtained.

IPC: H02P27/06
Filed: 1986-01-24
Abstract: PURPOSE:To prevent a steam turbine from being operated when the load of the turbine is lower than the minimum allowable load by controlling a motor with a load calculated by subtracting the minimum allowable low load of the turbine from the full load of a load machine as a maximum value of the sharing load of the motor. CONSTITUTION:A process signal 20a of process side such as a pressure signal is detected by a pressure converter 20, input to a power limiter 19, a full load required for a load machine is calculated, and the maximum allowable load of a steam turbine 6 is subtracted from a limit signal 19a from the limiter 19. This value obtained by the subtraction is used as the upper limit of the load power of an induction motor 4, and compared with a power signal 9a from a power detector 9. Thus, when the signal 9a of the detector 9 exceeds the upper limit value, the value of a power reference signal 12 is forcibly reduced to prevent the turbine 6 from being operated with the minimum allowable load or lower.

Title: Semiconductor optical waveguide element
Inventor: TSUZUKI TAKESHI
IPC: G02F1/313
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To prevent a function from being damaged by structural weakness on the surface of an element, to improve yield and to enable efficient mounting by bringing the height of the surface of the element in contact with the edge part of a protection film equal with or higher than the upper surface of an optical waveguide. SOLUTION: Most of a semiconductor optical waveguide 2 existent inside a semiconductor optical waveguide element 100 is covered with a protection film 3 composed of a polyimide resin, and only an electrode pad 4 for performing electric wiring with the outside is exposed on the surface. Since the height of the surface of the semiconductor optical waveguide element 100 in contact with the edge part of the protection film 3 is equal with the height of the upper surface of the semiconductor optical waveguide 2 covered with the protection film 3, vertical stress is hardly loaded from the protection film 3 to the semiconductor optical waveguide 2. Besides, the height of the upper surface of the semiconductor optical waveguide 2 is made lower than the height of the protection film 3 so as not to contact the both as well.  In that case, the upper part of the semiconductor optical waveguide 2 becomes air and an effective refraction factor is not changed by the mounting of the protection film 3.

Abstract: PURPOSE:To enable to detect the position of end of playing for two types of different record discs from the diameter, by using a photointerrupter as a pulse generating means and operating the gate start circuit producing pulses respectively through the photodetection and interruption by a photoelectric conversion element. CONSTITUTION:In playing an LP record disc, a selector switch 8 is selected to the 30cm position to start playing disc. In this case, a shutter plate 4 is inserted between a light emitting element 5 and a photoelectric conversion element 6, inhibiting the signal for the 1st start circuit 7 to operate a gate circuit 16. Since the 2nd start circuit 9 produces no signal to the gate circuit 16 at the same time, the drive motor 19 for the tone arm automatic return is not operated. When the playing is finished and light passes through from the through-hole 4a of the shutter plate 4, a signal is fed to the start circuit 20 of the drive motor 19 at the output terminal 16c of the gate circuit 16 with the output from the first gate start circuit 7 for the automatic return of the tone arm.

Abstract: PURPOSE:To communicate through a reserve loop at a time when both main and reserve loops are normal by providing a change-over switch in accordance with priority order between a communication control part containing terminals of low-order priorities and a loop interface part. CONSTITUTION:In case the loop transmission lines 4, 5 are both normal, the interface parts 6, 7 are connected to the communication control parts 10, 11 by the change-over switch part 8, but if a fault occurs on the optical fiber 4 side, the switch 8 switches so that the interface 7 and the control part 10 which is connected to a terminal of a high importance are connected with each other, and thus the communication with the terminal connected to the control part 10 is secured. In case a fault occurs on the optical loop 5 side, the switch 8 remains as it is, and the communication with the terminals of less importance connected to the control part 11 is cut off, and thus the communication through the control part 10 is secured.
