Title: Control device for magnetic bearing
Inventor: ISHIDA KIYOSHI
IPC: F16C32/04
Filed: 1987-07-06
Abstract: PURPOSE:To effectively work generating force for damping deviation by lagging a deviation control command signal in a rotary coordinate system, with a lag further added to a lag at a force generating portion in such a manner that the sum of them amounts to a lag for one rotation, and converting same to a fixed coordinate system. CONSTITUTION:A magnetic bearing is adapted to generate two magnetic attraction forces from coils 71-74 through phase compensators 31, 32, distributors 51, 52 and power amplifiers 61-64 according to signals x, y for detecting orthogonal displacement of a rotary shaft. In this arrangement, according to output of a synchronous two-phase oscillator 13 adapted to receive a rotational reference position pulse P, a fixed coordinate system through differentiators 81, 82 is converted to signals X, Y on a rotary coordinate by a coordinate converter 9, and converted to a fixed coordinate through a low-pass filter 10 by a coordinate converter 11. According to a speed signal VH from a function generator 14, a lag is further added to a lag at a force generating portion and lag coordinate conversion is conducted in such a manner that the sum of the above lags amounts to a lag for one rotation, that is, 360 deg. to compensate a lag. Thus, lag of the amplifiers and electromagnets are compensated to generate synchronous damping force and reduce deviation.

Title: Pattern detecting method
Inventor: ANDOU SANETOSHI
IPC: G01B11/24
Filed: 1979-12-22
Abstract: PURPOSE: To make measurement condition constant while improving the SN ratio of a pattern signal, by holding invariably constant the lower limit of the output voltage of a provided circuit that projects light upon a wiring pattern printed on a printed circuit board, detects and holds a minimum voltage to its transmitted light and then finds the difference between a detection voltage to the transmitted light and the minimum value.  
     CONSTITUTION: A wiring pattern printed on a printed circuit board is scanned with light and signal Vi obtained by detecting its transmitted light through a photodetector is inputted to input terminal 51 of amplifier 56 of detecting-holding circuit 52. When Vi is lower than minimum-value voltage securing voltage +VR, diode D1 turns on and circuit 52 outputs Vi. In the inverse case, D1 turns off and the output is supplied starting at VR and increases with the time constant determined by capacitor C and resistance R, maintaining the minimum value voltage. The output has the maximum value limited by voltage limiting circuit 53, whose output is subtracted from the input signal by differential amplifier 54, the output of which is biased by E2 through amplifier 55 and outputted to output terminal 57. Thus, the SN ratio of a pattern signal is improved and measurement conditions can be made constant.

Abstract: PURPOSE:To improve the transmission efficiency by reducing a processing time relating to a token. CONSTITUTION:When a station 2 passes a token to a station 3 and detects it that the station 3 is in the fallout from the token system, the station 2 executes the fallout processing as to the station 3 to set a station 4 to a transmission destination address of a transmission token frame, sets 'state change presence' to state change information of a transmission token frame and sets its own station address to a state change detection station address. The station 2 transfers ring configuration station information held by its own station to a transmission token frame and sends the result to the station 4. The station 4 receiving the token frame executes the fallout processing and sets 'state change presence' to the token frame to a succeeding station and transfers ring configuration station information and a state change detection station address held by its own station and passes the token to the succeeding station.

Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To make it possible to maintain the display quality of a plasma address liquid crystal panel over the lifetime of this panel by balancing the concentration of the dopant gas in a storage material and the partial pressure of the dopant gas in a hermetically closed space. SOLUTION: A plasma channel 20 is coupled to a manifold channel 30. This manifold channel 30 is coupled to a vessel (gas source) 34. The inside space of this vessel 34 and the inside space of the panel are hermetically sealed from outside the panel. The vessel 34 includes tablets 38 of the hydrogen storage material. If this hydrogen storage material exists in a closed chamber, the concentration of the hydrogen held in the storage material is balanced with the partial pressure of the hydrogen in the chamber. Then, the partial pressure of the hydrogen in the panel drops and the hydrogen is released from the storage material as the hydrogen is consumed by the use of the panel. The slightly dropped partial pressure is balanced with the slightly decreased concn.

Abstract: PURPOSE:To manufacture an organic nonlinear optical material containing an intra-molecule charge moving compound and having a stable nonlinear optical characteristic for a long period with high productivity by polymerizing a specific composition material while the external field such as the electric field is applied. CONSTITUTION:A composition material containing an intra-molecule charge moving compound, a liquid crystal and a polymerization compound is polymerized while the external field is applied. The composition material is pinched between substrates with electrodes, and the external field, e.g. the magnetic field, is applied across the electrodes to polymerize the composition material. Light is fed to the nonlinear optical material, and the outgoing light with the wavelength shorter than that of the incidence light is obtained. The intra- molecule charge moving compound has aromatic rings such as benzene rings or naphthalene rings in the molecule, and it has electron donating groups and electron attracting groups. A material with the nematic or smectic phase can be used for the liquid crystal. A monomer or an oligomer polymerized by mixing, heating, or irradiation of ultraviolet light or visible light may be used for the polymerization compound.

Abstract: PURPOSE: To add a specific flavor to popcorn after cooking with a microwave oven by filling a first compartment with kernels of corn to be popped at high temperature and storing an additive in a second compartment separated from the first compartment. CONSTITUTION: A corn 34 to be popped is contained in a first compartment 32 of a package 10, a flavoring composition 42, e.g. one to impart a cheese flavor to the popcorn, is put in a second compartment 40, the package 10 is kept in a cooled state. When the package 10 is first placed in a microwave oven 70, it has a relatively flat appearance. As the kernels become large, the compartment 32 becomes large gradually by pleats 16a, 16b, 18a, 18b. Finally, a fold 26 is separated due to a sufficient increase of pressure, and strip sections 50, 52 are in an enlarged relation with each other by separation of adhesive spots 50, 60, 62, 64. When the two compartments 32 and 40 are connected to each other, the additive 42 is dispersed by shaking the package 10.

Abstract: PURPOSE:To eliminate turning of flying of discharged ink drops and reciprocal interference among adjacent nozzles and heighten durability to wiping operation. CONSTITUTION:In a nozzle plate 2 having nozzles 3a, 3b, 3c... to be connected to an ink chamber, inkphilic surfaces 6a, 6b, 6c are formed around vicinity of the nozzles 3a, 3b, 3c on the surface at ink drop discharging side and ink- repellent surfaces 7 are formed at the outsides of the inkphilic surfaces 6a, 6b, 6c. When a recording ink is of water base, ink films are formed on the inkphilic surface 6, so that ink drops to be discharged go straight and fly. As the adjacent ink-repellent surfaces 7 are respectively independent, when a head moves, reciprocal interference of the ink films is a little. As the ink- repellent surface 7 is made to be high, the durability of the inkphilic surface 6 to wiping operation is heightened.
