Title: Magnetic bearing device
Inventor: INOUE MASAO
IPC: F16C32/04
Filed: 1990-08-28
Abstract: PURPOSE:To rotatably drive a rotor while supporting it in non-contact by the use of a single stator and coil by controlling displacements of the rotor on the basis of the amplitude of a current, and simultaneously, changing a phase of the current so as to rotate a magnetic field produced by the coil around the rotor. CONSTITUTION:An induced current is generated in a rotor 2 in the same principle as that of an induction motor. Interaction between the induced current and a magnetic field produced by a coil applies rotation driving force in the clockwise direction to the rotor 2. Adjustment of a current switching speed of the coil wire can control a rotating speed of the rotor 2. Attraction force exerted on the rotor 2 is dependent on an absolute value of the current flowing in the coil wire 3 irrespective of the direction of the current flowing in the coil wire 3. If a displacement (x) of the rotor in the lateral direction and a displacement (y) thereof in the vertical direction are measured, suitable adjustment of the attraction force can control the vertical and lateral positions of the rotor 2 in the sheet.

IPC: H04N5/66
Filed: 1989-09-02
Abstract: PURPOSE:To prevent lateral stripes from being formed owing to an offset oppositional deviation even when a voltage applied to picture elements is asymmetrical to the zero level owing to the offset oppositional deviation by setting the selection order of the polarity of the signal voltage applied to the picture elements irregularly between columns of the picture elements. CONSTITUTION:A video signal VIDI processed with polarity inversion corresponding to picture elements of odd numbered lines and a video signal VID2 processed with polarity inversion corresponding to picture elements of add numbered lines are sent to a common source driving circuit 13, which applies a signal corresponding to the video signal VID1 to corresponding odd numbered source lines according to the video signal VID1 and also applies a signal voltage corresponding to the video signal VID1 to corresponding even numbered source lines according to the video signal VID2. The selection order of the polarity of the signal voltage applied to the picture elements of the odd numbered lines, however, is different from the selection order of the polarity of the signal voltage applied to the picture elements of the even numbered lines and, therefore, lines of picture elements applied uniformed with the signal voltage having the same polarity never move up and down at every field according to the line order.

Filed: 1986-09-26
Abstract: PURPOSE:To obtain the title polymer which is excellent in weathering and chemical resistance, has flexibility and can form a transparent film, by copolymerizing a fluorinated olefin with a plurality of specified vinyl ethers and a function-containing monomer. CONSTITUTION:About 20-70mol% fluorinated olefin (A) (preferably, tetrafluoroethylene) is copolymerized with about 10-40mol% 2-chloroethyl vinyl ether (B), about 10-40mol% alkyl vinyl ether (C) (e.g., ethyl vinyl ether) and about 1-15mol% function-containing monomer (D) (e.g., 4-hydroxybutyl vinyl ether). Generally, a fluorinated polymer is excellent in weathering and chemical resistance, and especially when tetrafluoroethylene is used, these properties can be further improved. Although the transparency of the obtained copolymer is injured when component C alone is copolymerized, it can be improved by the incorporation of component B. Component D introduces a curing part necessary to form a cured film of the copolymer and improves the adhesiveness, solvent resistance, etc. of the cured film.
