IPC: H02P23/07
Filed: 1988-07-06
Abstract: PURPOSE:To improve torque control precision all the more by finding various controlled variables in consideration of the core loss depending not only on the primary frequency of an induction motor but also its secondary frequency. CONSTITUTION:A speed regulator 5 amplifies the deviation between a speed set value omega and a speed actual value omega2 to be found from the output of a speed detector 3.

Title: Device for changeover of anode of flat display screen
Inventor: BERUNAARU BANKARU
IPC: G09G3/22
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To obtain the flat display screen equipped with a microchip which switches fluorescent elements supporting conductor strips of anodes by applying a voltage lower than a minimum cathode voltage at least temporarily by a control circuit that is so adapted as to address respective groups in sequence. SOLUTION: The stationary voltage of a fluorescent strip is a voltage VA1 which is lower than the minimum bias voltage of the cathode microchip. In an example of interest where a cathode array is biased between 0-30V as a function of desired brightness of a pixel of a color in question the negative voltage VA1 is selected. Therefore, when one group is not addressed any more, the corresponding transistor MN turns on and the conduction strip of this group is held at the negative voltage VA1. Consequently, the capability of the fluorescent strip for attracting electrons emitted from the microchip is suppressed by quickening discharge between a fluorescent element and the strip supporting the fluorescent element.

Title: Automatic beam amount controller
Inventor: IWAI NOBUO
IPC: H04N5/228
Filed: 1981-10-21
Abstract: PURPOSE:To prevent the generation of false signals, by controlling the amount of beam of an image pickup tube and reducing the rate of change in the amount  of beam. CONSTITUTION:A video signal from an image pickup tube 1 clamped at a clamp circuit 4 is applied to a clip circuit 13 and a control circuit 14. The control circuit 14 detects the amplitude of the supplied picture and changes the clip level of the clip circuit 13 in response to the amplitude, to control the beam amount of the tube 1. When the amplitude of the video signal is a predetermined level or below, the clip level is set to a prescribed value. Thus, since a voltage applied to a grid 9 of the tube 1 is made constant, the generation of a false signal, i.e., framing signal can be prevented.

Abstract: PURPOSE:To improve the drape of a gate insulation film at the edge of a metallic layer by a method wherein the stepwise differences between the gate and an insulation substrate which is the base by filling the periphery of the gate with an insulation layer. CONSTITUTION:A Cr gate film 2 of approx. 2,000Angstrom  thickness is selectively formed on a glass plate 1, and a photo-permeable SiO2 film 13 of the same thickness and a negative photosensitive resin film 14 are put thereon. When the films are developed by irradiation with a large amount of ultraviolet rays 5 from the back of the substrate 1, a resin pattern 14' having an aperture 16 slightly smaller than the Cr film 2 can be obtained.
