Title: Regenerative control method for motor and motor driver with regenerative function
Inventor: UETAKE AKIHITO
IPC: H02P6/08
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To realize regenerative operation while ensuring detection accuracy of the rotational position of rotor by performing the regenerative operation for returning power generated in an exciting coil to the power supply side during an interval when an exciting current is not fed to the exciting coil. SOLUTION: Even during an interval when an exciting current is not fed to each exciting coil 25-27, power generated in each exciting coil 25-27 can be regenerated to a smoothing capacitor 31 on the power supply side during commutation spike voltage generating interval and delay interval at the time of determining conduction switching timing. Consequently, rotational position of rotor is detected based on a counter electromotive force induced in each exciting coil 25-27 of a three-phase hybrid stepping motor 28. According to the arrangement, regenerating braking can be performed while ensuring detection of the rotational position of rotor even for a sensorless three-phase hybrid stepping motor 28.

Inventor: NAKAMURA HARUO
IPC: G02F1/133
Filed: 1982-11-18
Abstract: PURPOSE:To obtain a liquid crystal light bulb by which a low cost and a high speed property are compatible, by executing N-time division driving, and making the voltage amplitude of a single applied to a write selecting electrode larger than the voltage amplitude of a signal applied to a data signal electrode. CONSTITUTION:A data signal has a voltage level of +V1/2 and -V1/2, and write selecting signals C1, C2,... have a voltage level of +V2/2 and -V2/2. In case of N=4, and V1=28V and V2=40V by using a liquid crystal light bulb containing a nematic liquid crystal composite in which cross frequency for setting dielectric anisotropy to zero is <=100kHz at a normal temperature, a light transmission response characteristics shown in the figure is obtained. 700 and 702 are responses to C1 and C2, and 701 and 703 show light leakage in other time than the assigned time of C1 and C2. A data signal circuit is reduced by executing the time division driving, and a speed drop of the liquid crystal light bulb, which is caused by the time division driving is prevented by raising only the output voltage of the write selecting signal.

Title: Erasion heat device
Inventor: AOI TAKAHISA
IPC: G11B5/024
Filed: 1982-11-17
Abstract: PURPOSE:To eliminate the erasion current at the time of video recording, to decrease the number of circuit parts and at the same time to reduce the power consumption of a VTR, by using a permanent magnet erasion head for full-width erasion and attaching and detaching the erasion head to the tape surface by means of a solenoid. CONSTITUTION:For a permanent erasion head 20, N and S multi-pole reducing alternating magnetic fields are formed on the rubbing surface of a tape 90 in the traveling direction 91 of the tape 90. The number of alternating poles is set at 11. The erasion noises and strains are reduced less as the number of poles increases to the limited head length. The width (d) of the first N and S poles 90-1 and 90-2 is set larger than that of subsequent ones among many alternating magnetic poles. As a result, the erasion factor is secured in response to a recording medium of high reluctance force in particular. About 0.3mm. erasion factor is obtained in case a head material uses barium ferrite or strontium ferrite. The head 20 is put on a head pedestal 21 and is brought into contact with the tape 90. The pedestal 21 is attached rotatably to a supporting shaft 22 which is implanted on a main substrate 50.

Title: Speaker unit and production thereof
Inventor: TOYOFUKU KENICHIRO
IPC: H04R7/18
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To reduce vibration reflections and to improve acoustic characteristics by tightly fixing an edge part, which is molded integrally with a gasket part while controlling the foaming magnification of the gasket part, and a diaphragm part while controlling the foaming magnification of the edge part. SOLUTION: Between an edge part 12 integrally molded with an elastic foaming material and a gasket part 15, an internal loss is continuously changed by increasing the foaming magnification of the gasket part 15 from the side of the edge part 12 to the outside and the vibration reflection is prevented by attenuating vibrations, which are propagated without being completely attenuated by the edge part 12, by the gasket part 15. The thickness of an outer peripheral terminal part 14a of a diaphragm part 14 is continuously decreased toward the outside. The foaming magnification of an edge inner peripheral terminal part 12b is decreased toward the diaphragm 14 and tightly fixed with the outer peripheral terminal part 14a at a joint part 20 by hot press without interposing a bonding agent.  Thus, the vibrations from the diaphragm part 14 can be attenuated in the joint part 20 and the reflection of vibrations hardly occurs. Further, the thickness of bonding can be made equal with the thickness of the diaphragm 14 by suppressing the gap of vibration propagation caused by the difference of materials.
