Title: Controller for number of rotation of rotary recording medium
Inventor: YAMAGISHI TORU
IPC: G11B19/28
Filed: 1985-09-03
Abstract: PURPOSE:To smoothly take out a reproduction signal from a part of juncture of old and new recordings by so constituting the titled controller that, in case of recording in a disc in sequence to its already-recorded part, a linear speed is obtained by reproducing the recorded part, a rotary angular speed from the linear speed and a positional information and by changing over a reproducing mode to a recording mode, then changeover of the mode is executed as keeping the linear speed constant. CONSTITUTION:First, a switch S is connected to a terminal P and the already- recorded part is reproduced, and the current number of rotation is obtained. Using the information of the number of rotation and the positional information from an A/D converter 10, the linear speed is obtained by an equation: Linear speed = radius X rotational angular speed. Then, using the linear speed obtained and the positional information from the A/D converter 10, the rotational angular speed is obtained by an equation: rotational angular speed = linear speed/radius. The rotational speed obtained is converted to a correspondent drive signal by a D/A converter 12, and is supplied to a motor 4.

Title: Gate drive circuit for voltage-driven semiconductor device
Inventor: MATSUBARA KUNIO
IPC: H02M1/06
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To lower a spike voltage at turning off, and to shorten the operation starting time by clamping a gate voltage at turning off to a voltage between a reverse bias voltage and a threshold voltage only for a constant time, and returning it to the reverse bias voltage after that. SOLUTION: If a signal changes from an on-signal to an off-signal, a transistor TR4 is turned on instantly, and a current flows between the base and the emitter of a transistor TR3 and turns it on. Following this, charging of the capacitor (input capacity) between the gate and the emitter of an insulated gate bipolar transistor IGBT is started toward a reverse bias voltage, and the insulated gate bipolar transistor IGBT starts its turn-on operation. Then when it reaches the zener voltage VZD1 of a zener diode ZD1, the transistor TR3 is turned off, and the charging into the input capacity of the insulated gate bipolar transistor IGBT is stopped and the voltage between the gate and the emitter is clamped. Here, the value of the zener voltage VZD1 is set to a value, which makes the gate voltage a value between a threshold voltage and the reverse bias voltage.  If the transistor TR4 is turned off, if time set by a timer passes after inputting of an off-signal, a gate voltage clamping circuit GC is cut off, and the insulated gate bipolar transistor IGBT is turned off by the reverse bias voltage.

Title: Rotary compressor
Inventor: MURAMATSU SHIGERU
IPC: F04C18/356
Filed: 1985-09-04
Abstract: PURPOSE:To prevent resolution of coolant and obtain a compact and a highly efficient rotary compressor, by forming a vane of the rotary compressor to compress a coolant including bromine elements, of a carbon with a metal melted and impregnated therein. CONSTITUTION:A vane 7 of a rotary compressor which uses a coolant containing bromine elements, R13B1 or the like, is formed of a carbonic material with a metal such as aluminum melted and impregnated therein. As a result, the temperature of the vane 7 does not rise so much owing to a self-lubrication of the carbonic material and a thermal radiation of aluminum, preventing to promote a resolution or the like of the coolant gas. Moreover, since carbon has no catalystic reaction, the resolution of the coolant can be also controlled from this respect.

Also, the conductance 3 of the dummy cell 23 is less than 13.5/2 of the sum of the conductance of the memory cell that is storing the '1'-information and '0'-information.

Abstract: PROBLEM TO BE SOLVED: To enlarge an apparent visual field angle by making a device a constitution in which a halftone reproducibility correcting means performs a halftone reproducibility correction with respect to luminance signal lower than a reference level to improve the deterioration of visibility accompanying black inversion and black paint out phenomenons. SOLUTION: This device detects parts continously having luminance information of luminance lower than the luminance signal in a video signal and applys different half-one reproducibility correction pixel to the parts every pixel. That is, a pixel (a) and a pixel (b) are parts continously having luminance information of luminance lower than the luminance signal in the video signal and at this time, when an area having information of low luminance is large in a screen (in one frame)., a black inversion and a black paint out effect the degrading of picture guality for viewers. Then, when pixels (a), (b) continously having information of low luminance exist, it prevented from occurring that the black inversion and the black paint out occur simultaneously by applying different halftone reproducibility correction every pixels (a), (b).  Consequently, the apparent visual field angle is enlarged.
