Filed: 1987-08-27
Abstract: PURPOSE:To obtain rotary torque of fixed level with no relation to the rotary angular position of a rotor at all times, by providing three- or more-phase stator coils and taking interlinkage magnetic flux with the stator coils into consideration. CONSTITUTION:A brushless DC motor is constituted of a rotary shaft 1 and a rotor magnet 17 or the like mounted to a rotor yoke 3. This rotor magnet 17, using a permanent magnet magnetized into two or more poles, is magnetized in a manner wherein the magnetic field by this permanent magnet obtains a sinusoidal wave. While providing stator coils in three phases, the stator coil connects in series winding blocks C1-C2, arranged in a position wherein the winding blocks are in the same phase to each other for the magnetic field by the rotor magnet 17, forming the first stator coil 18 similarly the second-third stator coils 19-20. Further corresponding to these coils 18-20, three Hall elements 21-23 are provided serving as the detecting element. By the structure thus obtained, fixed torque can be always obtained with no relation to a rotary angle of a rotor.

IPC: G06F12/16
Filed: 1994-09-07
Abstract: PURPOSE: To prevent data alteration due to writing from another port device at the time of read modify write operation for a read by one port by indicating specific read and write access acknowledgement timing to respective port devices. CONSTITUTION: Each port device 10 is equipped with a grant generating device 11 which indicates mutually exclusive read and write access acknowledgement timing periodically and a means which allows no command to be issued in a next cycle when the port device 10 is allowed to perform read modify write operation. Namely, the port device 10 can perform reading operation in read modify write mode in given timing and then the port device 10 having done the reading operation can perform neither reading nor writing in a next cycle. Therefore, writing operation to an address put in read modify write mode by other port devices 10 is never allowed and correct execution is performed.

Title: Data processing system capable of inputting plural video inputs
Inventor: HASHIMOTO YOJI
IPC: H04N5/268
Filed: 1989-08-19
Abstract: PURPOSE:To attain stable operation of a data processing system by monitoring whether or not a video signal reaches each video input terminal and not selecting a video input terminal having no video signal. CONSTITUTION:A selection circuit 5 is switched sequentially for a period of vertical synchronizing signal of an inputted video signal and a decision circuit 9 decides whether or not a video signal comes to each video input terminal and the result is stored. When an input selection signal A is instructed to be changed to other video input terminal, no signal is outputted when the video signal is not given to the other video input terminal and when the video signal exists, it is outputted as an input selection signal B as it is to switch the input. Thus, the unstable state of the entire system is prevented due to the absence of the input signal and the system is stably operated.

IPC: H01M4/62
Filed: 1982-12-08
Abstract: PURPOSE:To increase life without decreasing battery performance by covering the surface of a plate with a solid layer comprising acid resistant and electrochemically inactive oxide powder, water absorbable high polymer fibers, and a binder. CONSTITUTION:2-5g of polyacrylonitrile fibers having a length of 10mm. are mixed to a mixed solution of acid resistant and electrochemically inactive powder such as alumina, and monobasic aluminum phosphate as a binder. This mixture is spreaded on the surface of a positive plate that formation is not yet applied, and dried to form a solid layer. Thereby, a plate for a lead-acid battery is prepared. Since water absorbing ability of fibers excels in a neutral or alkaline solution than in acidic solution, absorbed water is released and large pores are formed in the solid layer. Thereby, dilute sulfuric acid is easy to diffuse and coming off of the active material caused by forming fine particles is suppressed, and life is remarkably increased.

Abstract: PURPOSE:To display a target in a corresponding size to the size of the target by detecting a discrimination mark of image data for an image memory, and forming a symbol mark corresponding to the size of the target of the discrimination mark which is preliminarily memorized, to be displayed. CONSTITUTION:An operator first puts discrimination marks and their sizes in a memory 7 to be memorized. When an usage of a vessel is stored in an image memory 3 next, a discrimination mark detecting means 5 detects the discrimination marks for the image in each bearing. A discrimination mark determining means 6 then compares them with the discrimination marks memorized in the memory 7, and if they coincide, the size of a vessel corresponding to the discrimination marks memorized in the memory 7 is read, and a symbol mark corresponding to the size is formed. An outputting means 10 renews the image for the discrimination marks detected by the memory 3 into an image mark of a formed size, and the image, symbol mark, etc., in the image memory 3 are displayed in a display 4. The operator can thus be known of the size of the vessel at a sight, and make instructions for safety navigation.
