Title: Servo system for rotating recording medium
Inventor: WACHI SHIGEAKI
IPC: G11B21/10
Filed: 1985-01-31
Abstract: PURPOSE:To reduce the normal deviation of an error signal relative to an objective value and to improve follow-up of a servo system under high speed rotation by converting the objective value of calculation outputted from a memory into a control signal, and supplying the result to an object to be controlled by a feed forward system. CONSTITUTION:In a tracking servo system for an optical disk, the disk is loaded on a recording and reproducing device and an objective value calculated from a tracking error signal for one revolution obtained without applying tracking servo is supplied through a corrective circuit M to a reverse system circuit 1. The circuit 1 generates an arithmetic control signal corresponding to the eccentricity of an optical disk, then supplied by a feedforward system to an object P to be controlled. Then, the displacement of the object P is made almost equal to the objective value and the feedback servo loop passing through a coefficient multiplier K2 acts as a control circuit effective to track deviation due to unforeseenable disturbances.

Title: Power source switching equipment
Inventor: MORI YOSHIAKI
IPC: H02J3/00
Filed: 1988-01-28
Abstract: PURPOSE:To prevent many loads from being connected to the power source at the time of recovery after the power failure, by providing a memory means to recover a switchyard which controls a breaker to open or close to the condition before the power failure at the time of recovery after the power failure. CONSTITUTION:In the condition where a load 5 is connected to the power source, the output voltage of a transformer 10 is supplied to a keep relay 33 and a relay contact 33 is closed. A memory means 30 memorizes that the switch 18 of a breaker 3 at a switchyard 7 is in a closed condition. When instantaneous partial power failure arises and after that the power is recovered in this condition, a current flows to a timer 42 from the transformer through the contact 33A. The timer 42 closes the relay contact 42A of a holding circuit after the specified time since the current application. Hereby, an electromagnetic coil 20 is energized to close the breaker 3. Next, when a load 5 is separated from the power source, the relay 33 is energized and the contact 33A is opened. In case that the power source is recovered after the power failure in this condition, since the contact 33A is open, the timer 42 does not operate and the load 5 is not connected to the power source.

Title: Loading device of low noise steel tube
Inventor: SATOU KATSUTOSHI
IPC: B65G47/78
Filed: 1979-02-16
Abstract: PURPOSE: To reduce the noise when loading steel tubes by successively changing position of the end of the transfer system so as steel tubes bump at ends one after the other.  
     CONSTITUTION: The steel tube 25 is brought in by the kicker 24, and rolls over the skid-rail 11, and subsequently transferred to the cradle 30 by the transfer skid 15. And when the transfer skid 15 is coming back to the original position leaving the steel tube 25 on the cradle 30, the end of the steel tube on the side of the transfer skid 15A drops on the cradle 30 as the end of transfer skids 5AW15C is installed with a difference of dimension of 1 respectively. In this instance, regardless of some large distance for the steel tube 25 falling down, bumping sound is small as it bumps only at an end. And, the steel tube is gradually loaded on the  cradle 30, being moved from the position of 15B to the transfer skid 15C, thereby remarkably reducing the bumping sound.

Title: Semiconductor logic circuit
Inventor: YAMASHITA KIICHI
IPC: H03K19/0952
Filed: 1985-02-01
Abstract: PURPOSE:To obtain a high speed logic circuit with low power consumption by coupling stages with a diode in case of the connection of two stages of direct coupling type logic circuits. CONSTITUTION:A drain voltage of a field effect TR (FET)12 is clamped by a voltage being the sum of a rising voltage of a gate-source of an FET16 and a voltage of a rising voltage of a diode 13. Since the high level is doubled than a conventional circuit, 1.2-1.6V of logical amplitude is obtained. Since a voltage is given dividedly to a diode formed with the diode 13 and a gate and source of the FET16 at ''0'' level, the FET16 halving the gate voltage in comparison with the conventional device is cut off completely. Moreover, when the power consumption is the same as the power voltage of a conventional example, the voltage is decreased by the share dividing the square of the diode rising voltage by a value of the resistor 11.

Title: Semiconductor delay circuit
Inventor: OKADA YOSHIAKI
IPC: H03K5/135
Filed: 1990-01-25
Abstract: PURPOSE:To control a control signal of a delay circuit within a variable range at all times by varying an ON-resistance of a MOS transistor(TR) largely through the addition or elimination of a MOS TR forming a delay circuit in excess of the control range of a control circuit. CONSTITUTION:When a period of a clock signal inputted from an external clock signal terminal 1, e.g. is increased, an output voltage of a phase comparator circuit 6 is decreased so that the phase difference of two input signals inputted to the phase comparator circuit 6 is made zero and the delay time of delay circuits 4, 5 is increased. When the period of the said clock signal is further increased, the voltage is decreased more than the voltage of a constant voltage source 10 and in output of a voltage comparator circuit 8 goes to a low level. The signal passing through two MOS TRs 37, 38 passes through only one MOS TR 39. Thus, the delay time of the delay circuits 4, 5 is decreased and the output of the said circuit 8 goes to a high level.

Title: Cover opening device for x-ray film cassette
Inventor: KAKUHARI HIROYUKI
IPC: G03B42/02
Filed: 1978-02-16
Abstract: PURPOSE: To ensure opening of the cassette without giving the second processing to the cassette and thus to secure carry-out of the film by applying the external force to the cassette to the catch part of which the cover opening component is engaged and then releasing the lock by shifting the catch.  
     CONSTITUTION: One-touch locking cassette A is inserted and adhered to cassette holding component 13 the left edge of which is supported rotatably by holding axle 12. Then lever 17 is pressed down to give rotations to pressing component 19 centering on axle 18, and thus roller 21 pushes down upper surface 1A of container 1 of cassette A to make the catch part of A engage with cover opening component 9. Then the sliding bar locking the cover shifts along with the shift of A in the X direction, thus releasing the lock. When the force applied to lever 17 is released, only container 1 held by component 13 rises upward to pen cover 2. Thus, the film inside cassette A can be carried out via roller 34 and 35.
