Title: Drive controller of synchronous motor
Inventor: KEN SHINOBU
IPC: H02P25/022
Filed: 1984-10-08
Abstract: PURPOSE:To reduce the cost of an induction motor in a drive controller of a synchronous motor using a resolver by reducing multipliers. CONSTITUTION:A synchronous rectifier 10 which inputs the output signal of a resolver 2 outputs triangular waves synchronized with the rotary angles thetaand theta+120 deg.. Limiters 11, 12 which input the output signals convert the triangular wave into trapezoidal waves. A mixer 13 has two multipliers 5, 6 and a subtractor 14, multiplies the current command signal (i) of the motor 1 by the output signals of the limiters 11, 12 by multipliers 5, 6, and further combines the output signals of the multipliers 5, 6 by the subtractor 14 to produce 3-phase current command signals of the motor 1.

Abstract: PURPOSE:To automate oiling to pivotal portions of a traction chain on which a plurality of containers for receiving small articles are mounted to travel along an elliptic rail, by detecting a projection on the respective pivotal portions of the chain to operate an oiler. CONSTITUTION:A warehouse for receiving small articles rotates a drive sprocket 7 by a motor 10 to rotate a traction chain 20 and move a plurality of containers 16 on both inner and outer rails 2, 3 through wheels 19. Then, when a microswitch 24 provided on the outside surface of an end of a guide groove 4 detects a roller 23 engaging the guide groove 4 extending in the moving direction of the container 16 on turning-around traction chain 20, an electromagnetic air valve is opened only for that period. Thus, an oil pump is driven by air pressure so that a proper amount of lubricating oil pumped from a tank is oiled to the respective pivotal portions of the chain 20 through a nozzle 27a.

SOLUTION: In a variable displacement compressor provided with a solenoid valve 19 for controlling a second communication passage 20 by an external, signal so that it may be opened and closed on the way of the second communication passage 20 for communicating a crank chamber 3 and an intake chamber 13 with each other, a passage extending from a crank chamber side opening part of the second communication passage 20 to a solenoid valve inlet side pressure chamber 20a, and a passage extending from a solenoid valve outlet side pressure chamber 20b to an intake chamber side opening part are installed in the positions lower than the contact position of a valve element of the solenoid valve 19 and a valve seat.  Moreover, a pressure control valve 16 for controlling a first communication passage 18 so that it may be opened and closed is provided on the way of the first communication passage 18 for communicating the crank chamber 3 and an intake chamber 13 with each other. When the solenoid valve 19 is closed, the differential pressure between the crank chamber 3 and the intake chamber 13 is adjusted by the pressure control valve 16 to change the tilt angle of a swash plate, and the piston stroke is changed to control the discharge capacity. When the solenoid valve 19 is opened, the piston stroke is maximized regardless of the opening and closing state of the pressure control valve 16.

Title: Optical pickup
Inventor: NAGASHIMA KENJI
IPC: G11B7/135
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To make a beam shaping prism outgoing light angle substantially constant even when a laser light wavelength is changed by canceling a bent angle of a beam shaping prism at the light transmission time with a light bent angle of a grating at the light diffraction time at every wavelength when the light emission wavelength of a semiconductor laser is changed within a prescribed range. SOLUTION: When the light emission wavelength (λ) of the semiconductor laser 1 is changed by Δλ, the refractive index (n) of the beam shaping prism 4 is changed also in proportion to the change Δλ, and a converged light spot position on an optical disk is changed also, and the correct recording/ reproducing is impossible. For evading this, the grating 11 is provided, and even when the wavelength (λ) is changed, the light bent angle of the grating 11 at the light diffraction time cancels the light bent angle of the prism 4 at the light transmission time by the changed wavelength. Since the grating 11 cancels the light bent angle of the prism 4 at the light transmission time by the light bent angle when light is diffracted at a prescribed pitch (p), the grating 11 has to have the suitable pitch (p).

Title: Heat cooking apparatus
Inventor: ISHIMURA YOZO
IPC: F24C15/16
Filed: 1990-08-08
Abstract: PURPOSE:To reduce the generation of smoke and make the time for heat cooking shorter by providing a second heater which is located between a net and a receiving plate for receiving an object to be heated and providing oxidation catalyst on the receiving plate so that fats and oils dropping onto said plate are oxidized and decomposed. CONSTITUTION:An object 3 to be heated such as a roast fish which produces a large amount of fats and oils is cooked. Since the surface temperature of a receiving plate 23 rapidly becomes higher than 350 deg.C by means of a second heater 25, even if fats and oils drop from the object 3 onto the plate 23, they are oxidized and decomposed to carbon dioxide and water by oxidation catalyst 24 on the plate 23. The catalyst 24 holds paricles 27 of oxides in the voids formed in entangled ceramic fibers 26, in which the voids is as high as tens of %, and hence the oxidation of fats and oils is easily effected. And the fats and oils scattered from the object 3 are sucked by an exhaust suction fan 11 provided at the rear of a main body 1 and passed through catalyst 12 so that they are decomposed to carbon dioxide and water, resulting thereby in reduced generation of smoke. Preferably, the surface temperature of the catalyst 24 on the side of the second heater is 350-400 deg.C or higher.

Title: Device for detecting and evaluating ink measuring field of printing paper-sheet
Inventor: ARUFUREETO DORUN
IPC: B41F33/00
Filed: 1983-11-11
Abstract: An apparatus to obtain ink density data by scanning color measurement strips on a printed sheet has a densitometer mounted on a digitally-driven X,Y positioning mechanism, an optical sensor for detecting the position and orientation of the sheet with respect to the X,Y positioning mechanism, and a numerical computer for transforming the sheet coordinates of the color measurement strips to the X,Y coordinates of the X,Y positioning mechanism. Thus, the numerical computer can automatically position the densitometer to scan the color measurement strips. In a first embodiment, optical sensor arrays determine the position and orientation of the test sheet with respect to the X,Y positioning mechanism. In a second embodiment, the densitometer itself scans the edge portions of the test sheet to determine the position and orientation of the test sheet. The operator has the option of using sheet coordinates of the color measurement strips obtained from non-volatile storage, from a recording medium such as magnetic tape or disk, from direct operator entry from a keyboard, or from the sighting of the measurement strips on the test sheet arbitrarily positioned and oriented with respect to the X,Y positioning mechanism.

Title: Liquid crystal element
Inventor: NAKANOWATARI JUN
IPC: G02F1/1343
Filed: 1986-09-08
Abstract: PURPOSE:To freely change the ratio of regions in an on state and off state and to permit medium contrast display by providing electrodes for impressing a bias voltage to display segments. CONSTITUTION:This liquid crystal element is formed by oppositely disposing two sheets of glass substrates 11, 21 formed with the transparent electrodes 12, 22 on the inside and filling a ferroelectric liquid crystal 25 exhibiting a chiral smectic C phase into the gap therebetween. The element is provided with the electrodes 13 for impressing the bias voltage to the display segments in addition to the transparent electrodes for display. The change over of the display within the segments is confined to the partial change-over and two states can be produced simultaneously by impressing the bias voltage to the display segments in the above-mentioned manner. Both of the two states are in the stable state when the two states are simultaneously produced in one segment. Said state is maintained unless the pulses above the threshold voltage is impressed to the segments. The medium contrast display is thus permitted by regulating the bias voltage to change the ratio of the two states in the above-mentioned manner.
