Title: Piezoelectric actuator
Inventor: SUZUKI YOKO
IPC: H02N2/00
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric actuator capable of stably operating, even in the case of fluctuations of a resonance frequency and a drive frequency of a displacing mechanism. SOLUTION: This piezoelectric actuator 100 comprises a rotary shaft 110, a support 120 having displacing mechanisms 123, a rotor 130, and a spring 140 for holding a contact of the rotor 130 with the support 120 under a fixed pressure. Since the mechanisms 123 adhered with piezoelectric elements 122 have different shapes for vibrators, the resonance frequencies of the mechanisms are also different. As a result, since a variable frequency range can be enlarged, as compared with the actuator constituted of the mechanism having the same resonance frequency, stable operation can be realized, even with respect to fluctuations in the resonance frequency and the drive frequency of the mechanism.

Title: Optical device using magnet-optical effect
Inventor: FUKUSHIMA NOBUHIRO
IPC: G02F1/09
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To give arbitrary attenuation to an optical signal of each channel for wavelength-division multiplexing(WDM) by applying a magnetic field so that the magnetism of magnetooptic crystal through which a light beam passes has a distribution given in a plane substantially perpendicular to the light beam. SOLUTION: A light beam outputted from a port 4 is brought into Faraday rotation by axis optical crystal 10 and the light beam is inputted to a port 8. A magnetic field application unit 12 applies the magnetic field to the magnetooptic crystal 10 so that the magnetism of the magnetooptic crystal 10 has the distribution given in the plane substantially perpendicular to the light beam. A 1st area 2 and a 2nd area 6 are so determined that the light beam between the ports 4 and 8 can pass through the magnetooptic crystal 10. Then the distribution of the magnetism imparted to the magnetooptic crystal 10 by the magnetism application unit 12 is so obtained that the magnetism vector slants to the light beam from the top to the bottom in the figure in the plane substantially perpendicular to the light beam.

Title: Magnetic tape control device
Inventor: TSUKADA SHIGERU
IPC: G06F3/06
Filed: 1993-11-16
Abstract: PURPOSE:To eliminate waste in using a magnetic tape and to effectively use a large capacity magnetic tape. CONSTITUTION:Volume table and plural volume IDs are set in a medium and a control means 7A is provided to control data--recording/reproducing by controlling it information. The means 7A recognizes the volume table information by a specific command, retrieves a specific volume ID region and records the data. In this control scheme, the medium is divided into plural regions with equal spacing and these regions are controlled. When an overlap occurs during a title writing, it is continuously recorded right after physically last data of the medium. Then, all of the following recorded data are saved in empty regions of the medium, data titles are written and the saved data are recorded right after the data. While performing a rewriting of a same volume ID, the previously stored data are constituted so that the data are restored in a new region after the last data.

Title: Method for parallel computation for power circuit
Inventor: ARAI JUNICHI
IPC: G01R21/133
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To shorten the waiting time of a CPU and thereby to shorten the time for computation as a whole in the case of parallel computation for a power circuit. SOLUTION: Generators 21, transformers 22 and loads 23 are connected to AC circuits 11A-11D respectively and the circuits are connected to each other by transmission lines 3a-3d. A power circuit is divided at the parts of the transmission lines and computation is conducted at a period of computation being equal to or shorter than a propagation time proper to each transmission line connected by a CPU. When the propagation time of the transmission line 3a is assumed to be 50.0μs, that of the transmission line 3b 10.3μs, that of transmission line 3c 3.8μs and that of the transmission line 3d 1.6μs, for instance, the period of computation is 1.6μs for the circuits 11C and 11D, 10.3μs for the circuit 11A and 3.8μs or below for the 11B.  Thus, the number of computations can be increased, with the waiting time lessened, in the same period of time for the circuits 11C and 11D, while a large number of computation factors can be included for the circuit 11A.

When a storage pattern is not coincident with the preregistered pattern, the stored pattern is rotated by an angle corresponding to the rotation angle per 1 pulse of a pulse motor 32, a counter is increased by 1 and the coincidence is checked again. The operation above is repeated and when they are coincident, the paper is directed in the set direction by giving drive pulses by the content of the counter to the pulse motor 32.
