Title: Control device for switching frequency of electric power signal applied to each phase winding of brushless commutatormotor
Inventor: JIEI AARU GEETSU
IPC: H02P25/08
Filed: 1992-02-20
Abstract: PURPOSE: To determine a mechanical angle of a rotor by providing a resonance tank circuit using one phase coil of motor as a variable inductance and detecting changes in the output amplitude of the resonance tank circuit due to a difference between the resonance frequency of the resonance tank circuit and frequency of a signal supplied. CONSTITUTION: A low power signal in a frequency of F1 is supplied to resonance tank circuits 59a to 59d , including phase coils A1 to D2 of an SR motor 15. Here, effective inductance of the phase coils A1 to D2 changes, depending on the change of a mechanical angle of a rotor 17, and thereby a resonance frequency F0 of the resonance tank circuits 59a to 59d also changes between maximum and minimum values. When the difference between the resonance frequency F0 and frequency F1 is minimum, outputs of the resonance tank circuits 59a to 59d become maximum. As explained, position of the rotor 17 can be analyzed through a relationship between the periodical changes of the resonance frequency F0 and the mechanical angle of the rotor 17. Moreover, changes in the amplitude of an output signal is detected, and the firing angle of each phase can be controlled using the result detected.

Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To provide an information processor capable of preventing hindrance of normal operation due to connection of an unexpected unit in a system in which mutual connection to allow change of data transfer overhead between units by the number of units to exist in the system or connection topology is adopted. SOLUTION: Unit information of the unit to permit connection is stored as a connection permissible unit list in a flash memory 3. The unit information is read from each unit and compared with the connection permissible unit list. A unit, which does not exist in the connection permissible unit list, is a connection impermissible unit. When the connection impermissible unit is judged to be a leaf unit from system topology, the connection impermissible unit is separated from the system and operated only by a specified unit. In addition, the connection impermissible unit is not the leaf unit, a start processing is interrupted.

Title: Ink absorption recovering device for ink jet recorder
Inventor: YAMAGUCHI HIDEKI
IPC: B41J2/18
Filed: 1990-03-22
Abstract: PURPOSE:To obtain an ink absorption recovering device by providing driving means for elastically deforming easily elastically deformable part of an elastic cap member when the ink discharging face of a recording head is sealed by the member. CONSTITUTION:A cap holder 10 is so pressed as to be moved forward to bring the end of an elastic cap member 7 into contact with a recording head 1 to be slightly deformed. Since the elastically deformable part 7B of the member 7 is elastically deformed to be externally pressed, the inner volume of the mem ber 7 is increased, introduction of the air into a nozzle is alleviated, and a meniscus in the nozzle is not retracted. Accordingly, an excellent printing is immediately performed without suction by a suction pump 6. If fine bubbles are generated and improper discharge occurs, the part 7B is pressed inward of the member 7. Since the inner pressure of the member 7 is suitably increased, large bubbles are generated in the head 1, and the fine bubbles are integrated. The pump 6 is started to discharge them out of the member 7.

Title: Controller for gravity-lowering speed of sluice uplifter
Inventor: SATOU SUNAO
IPC: E02B7/36
Filed: 1981-05-08
Abstract: PURPOSE:To constantly lower the gate of a sluice by using a system in which a closed circuit oil-pressure brake mechanism having a load resistance is connected to a gear-driving shaft and the load resistance is absorbed by an oil pressure generated from the closed circuit oil-pressure brake mechanism. CONSTITUTION:An oil-pressue circuit performs not only a braking function utilizing the fluid resistance of oil 23 by throttling a flow control valve 22 to a constant degree but also a function making the rotation of an oil-pressure motor 19 constant. In short, the oil-pressure motor 19 serves as a pump powered by the weight of the sluice gate, the oil pressure of the pipe 21 on the discharge side is increased when its rotation number if increased, and the oil 23 of the pipe 21' on the intake side becomes negative pressure. As the pressure difference between the discharge and intake sides is greater, a breaking action works on the rotation of the oil-pressure motor 19, whereby the number of rotation is reduced, a constnt-speed rotation results by a constant pressure difference, and therefore, the occurrence of a lowering acceleration in the sluice gate is prevented.

Filed: 1991-01-16
Abstract: PURPOSE:To prevent the deterioration of uniformity of emission due to the emission of a large amount of electrons from only a specific emitter in an electric field emitting element provided with a plurality of emitters. CONSTITUTION:An emitter unit 5 constituted of a plurality of emitters 4 arranged at predetermined intervals is mounted on an insulative substrate 2 apart from a common gate unit 7 and a common collector unit 8.
