Title: Generation system for color television still-picture signal
Inventor: TSUJI MASAKAZU
IPC: H04N11/00
Filed: 1979-03-30
Abstract: PURPOSE:To simplify the inter-frame color-phase matching of a still-picture color television signal by inputting picture-element outputs of a frame memory by two kinds of out-of-phase clocks and then by alternating them, frame by frame. CONSTITUTION:Signal data stored in one-frame memoy 101 are transferred to buffer registers 103, 104 and 106 by clocks of clock generator 102. Then, they are  further transferred sequentially from buffer register 103 to 105 by clocks delayed by  approximate 180 deg. through delay line 107. Next, picture-element outputs 203 and  204 are supplied to switch 108 and alternated, frame by frame, by a frame signal  from frame signal generator 109, thereby outputting picture-element 205. Therefore,  color phase shifts between frames disappear.

Filed: 1993-03-01
Abstract: PURPOSE:To reproduce a picture with high picture quality by controlling stepwise a black level generating quantity in response to a black edge so as to reduce a rapid change in a UCR rate. CONSTITUTION:The processing device is provided with a means outputting a multi-stage K signal from r, g, b signals or C, M, Y signals and a means calculating a black edge quantity of a noted picture element from the r, g, b signals or C, M, Y signals. In this case, a black edge quantity calculation section 7 is made up of a black level calculation circuit 8 and an edge quantity calculation circuit 9 and calculates a black edge level (n) of a noted picture element to provide an output to a black level generating circuit 4. The black level generating circuit 4 controls the generation of a block level in multi-stage according to K=alphaxmin (C, M, Y). The correspondence between the black edge quantity n, alpha is formed in a table and the black level quantity K is changed in multistage in response to an output (n) from the black edge quantity calculation section 7. Thus, a sudden change in an UCR rate in a picture is suppressed and the picture quality is improved.

Title: Overvoltage protective circuit
Inventor: SAITO SUMIO
IPC: H02H3/20
Filed: 1988-02-23
Abstract: PURPOSE:To prevent deterioration or breakdown of elements in a load circuit, by clamping the source voltage to a level smaller than a limit level when the source voltage exceeds over the limit level and interrupting power supply through a current interrupter, thereafter discharging a charge/discharge unit to the load circuit. CONSTITUTION:When abnormality occurs in a constant voltage circuit 1 and the output voltage reaches to 16.5V, current flows through the cathode K of an over voltage detector 21 to cause droppage of cathode voltage, and thereby the emitter voltage of a transistor TR2 drops to cause current flow between the source lines. Consequently, a part of the terminal voltage VD of the diode 50 is positive fed back through a resistor R8 to an over voltage detector 21 thus clamping the source voltage V to 15.5V, for example. As a result, current from the constant voltage circuit 1 increases abruptly to blow off a fuse F thus interrupting power supply to the constant voltage circuit 1. Thereafter a capacitor 23 is discharged gradually.

CONSTITUTION: Water-cooling copper plates 1 are supported with backup plates 2 to form long wall members of the mold. The molten steel 5 is supplied from an immersion nozzle 4. The molten steel 5 is prevented from the oxidation with powder 6 and cooled with the water-cooling copper plates 1 in the lubricating condition. Simultaneously, the mold is oscillated through an oscillation table, and solidified shell 7 is continuously formed and also, grown to obtain a continuously cast slab.

The electro- magnet 8a is constituted with the coil 9a which does not use an iron core but forms with a copper-made wire. The wt. of the electro-magnet 8a becomes 1/5 of the conventional magnet by using the air-core type.  Superconducting coil 9a is desirable to be used to the electro-magnet 8a in order to obtain the sufficient magnetic flux density.

Title: Optical disk device
Inventor: ITO NOBORU
IPC: G11B7/135
Filed: 1990-02-21
Abstract: PURPOSE:To efficiently convert a light beam into the form of a ring, and to make the diameter of a light spot small by using a beam converting means to convert emitted light from a light source into the ring-shaped light beam by using refraction. CONSTITUTION:The light emitted from a semiconductor laser 1 is turned into parallel light 13 by a condenser lens 2, and becomes incident on the beam converting means 12. The beam converting means 12 consists of conical surfaces A, B, and the light beam 13 is refracted simultaneously with it comes incident on the conical surface A, and next, it reaches the conical surface B, and here, it is refracted again and is emitted in the air. Accordingly, the emission light of the beam converting means 12 becomes parallel with the parallel light 13, and its shape becomes ring-shaped. Thus, since the beam can be converted into the form of the ring without shielding the light, all the emission light of the semiconductor laser 1 can be used. Thus, the ring-shaped beam capable of making the light spot small can be generated without being accompanied with the loss of the light at the time of converting.

Abstract: PURPOSE: To prevent the deterioration of reproduced picture quality, by giving the force at first to the detaching direction and next to the pressing direction until the steady state is reached, in returning the pickup of the grooved video disc to the signal groove already scanned.  
     CONSTITUTION: When the drive current flows to the coil 9 of the pickup 1, the force toward P, Q is given to the magnet 5 and the force F shifts the signal conversion section 4 toward the arrow. This force F is produced every time the second field pulse is detected after the compulsive feed of the pickup is stopped, and the stylus 3 is subjected to the returning force f based on the stress of the elastic substance 6. Accordingly, the stylus 3 is returned to the signal groove immediately before with the synthesized force of the force F, f and stylus pressure W. In this case, the signal from the pickup 1 enters the coil 9 of the pickup via the video processing circuit 10, vertical synchronizing separation circuit 12 and gate circuit 15 to increase the stylus pressure up to the steady state. Thus, the picture quality can be increased.

Title: Forming method of viahole
Inventor: OKUNISHI TATSUYA
IPC: B23K26/382
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To provide a forming method of a viahole which reduces thermal damage to insulating material of a lower layer while a laser light is used. SOLUTION: A pulsed laser light is cast on a board from above which has a structure sandwiching a plating layer between resin and an upper insulating layer. In a term A where the laser light is turned on, an irradiated part in the upper insulating layer is violently heated, scattered to make a hole. The heat is conducted to the periphery of the part. In a term B between pulses, heating is not performed and heat is only dispersed, so that the temperature of periphery of the irradiated part does not become excessively high. Thereby resin just below the plating layer is prevented from fusing and vaporizing. Hence the plating layer is not peeled from the resin just below the plating layer.
