Title: Optical type recording and reproducing device
Inventor: WADA KATSUTOSHI
IPC: G11B19/20
Filed: 1988-01-13
Abstract: PURPOSE:To improve the track following capacity of an optical pickup by adjusting the position of a disk against the revolving axis of a spindle motor and reducing the decentering of an information track. CONSTITUTION:A disk alignment mechanism is the bottom part of a disk cramp 8 and fitted into the center hole of a disk 9. A decentering correction calculation circuit 20 detects the decentering direction of the disk from a phase difference between a revolving synchronizing signal from a spindle motor 11 to be the reference of the coordinate on the disk and an optical pickup tracking actuator driving signal proportionate to the movement of the radial direction of the disk of the information track. A disk position adjustment signal is outputted in order to minimize the tracking error signal of an optical pickup 10. Thus, the tracking following control of the optical pickup is good in an accuracy and a control system having room for a disturbance can be attained.

Title: Clear signal generating circuit
Inventor: KAWASHIMA KAZUMI
IPC: H03K17/22
Filed: 1978-01-17
Abstract: PURPOSE:To ensure an assured clearing of the internal state of LSI at the ON/OFF time of the power source by generating the switching output in accordance with the integrating output of the power voltage. CONSTITUTION:If the voltage featuring waveform (I) is applied to terminal 8 in case the power voltage has a sudden change, the voltage at point B changes like waveform (J). On the other hand, the voltage at point C changes like waveform (K), and the collector voltage of transistor 14 which is to be the output voltage of the clear signal generating circuit features the change like waveform (L). Then in case the power voltage has a slow change, the voltage featuring waveform (O) is applied to terminal 8. Thus, the voltage at point B and C changes like waveform (P) and (Q), and the output of the generating circuit has the change like waveform (R). As a result, the clear signal to be applied to terminal 4a of LSI4 features the sudden fall and rise, and accordingly the assured clearing is secured for LSI4 even though the threshold voltage of the buffer circuit may differ.

Abstract: PURPOSE:To make it possible to detect the current in a switching transistor(STR) and thus the lower limit voltage of secondary batteries just by turning on a switch, by placing a discharge circuit composed of the STR and an overvoltage protective circuit composed of Zener diodes and the switch in parallel between the terminals of a set of secondary batteries. CONSTITUTION:A discharge circuit 2, composed of a p-n-p switching transistor (STR) Q1 and a resistor R2, is connected with both of the ends of a set of secondary batteries 1. An overcurrent protective circuit 3, composed of a resistor R1 and Zener diodes ZD1, ZD2, is connected with both of the ends of the battery 1 set. Point F of the overcurrent protective circuit 3 is connected with the base of the STR Q1. A switch 4 is connected in parallel with ZD2, and the secondary batteries 1 are charged by means of a charge circuit 5. Turning on the switch 4 will activate a path including the emitter and base of the STR Q1, ZD1 and switch 4. As a result the STR Q1 is turned on, and discharge is performed through a discharge path 2. When the voltage of the secondary battery 1 set falls below a specified value, discharging is stopped. Thus the lower limit voltage of the secondary batteries 1 is detected.

Title: High strength aluminum alloy and its manufacture
Inventor: KUROFUCHI TATSUFUMI
IPC: C22C21/16
Filed: 1981-01-16
Abstract: PURPOSE: To obtain a high strength Al alloy with improved casting crack resistance by adding specified elements to an Al-Cu-Mg alloy.  
     CONSTITUTION: This high strength Al alloy consists of, by wt., 4.0W5.5% Cu, 0.20W0.50% Mg, ≤0.15% Fe, ≤0.15% Si, 0.010W0.10% Ti, 2W20% B to Ti, 0.020W0.30% rare earth element and the balance essentially Al. Ti and B make the grains fine and prevent casting crack. In the coexistence with B, less than the lower limit of Ti produces no effect, and more than the upper limit of Ti enhances the effect slightly. Less than the lower limit of B produces the effect hardly, more than the upper limit of B enhances the effect slightly, and excess B forms a compound in molten metal together with Ti, tends to precipitate, and makes homogeneous casting difficult. The rare earth element contributes to casting crack prevention, yet it is required to be coexistent with Ti and B, less than the lower limit of the element produces no effect, and more than the upper limit of the element reduces the strength and elongation.

Title: Insulated gate field effect transistor
Inventor: KAYAMA CHIZURU
IPC: H01L27/04
Filed: 1990-01-12
Abstract: PURPOSE:To protect a gate, to improve a field effect transistor in dielectric breakdown strength when it is reversely biased, and to prevent a parasitic transistor from being made due to the formation of a Zener diode by a method wherein a one-way Zener diode is built in a polycrystalline silicon layer between a gate and a source. CONSTITUTION:Ions are selectively implanted into the polycrystalline silicon layer of a gate bonding pad 8 to form an N region 9 and a P region 10, and the N region 9 and the P region 10 are brought into contact with a gate electrode 11 and a source electrode 12 respectively to constitute a structure that a polycrystalline silicon Zener diode is built in between a gate and a source. The breakdown strength of the polycrystalline silicon Zener diode is made lower than that of a gate-source breakdown strength so as to prevent an over current from flowing through a gate. By this setup, a built-in Zener diode functions to protect a gate, a field effect transistor of this design can be sharply improved in breakdown strength when it is reversely biased, because the Zener diode starts operating, and as the Zener diode is not built in a bulk, a parasitic transistor can be prevented from being generated due to the formation of the Zener diode.

Filed: 1980-01-21
Abstract: PURPOSE:To enable a display moving speed of a display element to be decreased stepwise by successively selecting the different period pulses from a frequency divider successively from higher ones to lower ones by one time of switch operation. CONSTITUTION:Outputs Q32-Q1/2 (32Hz-1/2Hz) of an oscillating frequency divider 1 are inputted to AND circuits 3-8 which are inputted with flip-flops 33- 37 and 40. Further, a switch SW is being inputted to the flip-flop 40 via a resistance R, a chattering preventing one-shot circuit 2, flip-flop circuits 21, 22, and an AND gate 9. When the switch SW is closed, it outputs to a lead wire (d), to open the AND circuit 3, so that the outputs of the AND circuits 3-8 are connected. In an  OR circuit 15, of which output drives display elements, the output of 32Hz is obtained from Q32 and when the switch SW is closed succeedingly, an output is produced in a lead wire (g). Every time when the signal of Q1/2 is inputted to the  AND circuit 9, outputs are produced in lead wires (j)-(m) successively and therefore the moving speed of display elements is decreased stepwise.

IPC: G01J5/48
Filed: 1979-01-20
Abstract: PURPOSE: To reduce greatly a load on a navigating body by sending a pickup signal from the navigating body while changing visual fields by a command signal from a reception side, and then by converting it into an image through the canceling process of pattern noise at the reception side.  
     CONSTITUTION: Navigating body 1, equipped with pickup unit 2 functioning as an optical system, photoelectric converter and shift register, a commond signal receiver circuit, and visual-field switching unit, transmits a pickup modulated signal incuding fixed pattern noise. At the reception side, receiver circuit system 4 demodulates the received signal and then sends it to arithmetic circuit 7 by way of alternation switch 5. This switch 5 sends a signal derivd from an observation object to circuit 7 while sending that derived from a reference light source to memory ciruit 6. Circuit 7 normalizes a signal derived from the ground by the reference signal of circuit 6 to remove fixed pattern noise. The processed signal is converted by D/A converter 8 into an analog signal, which draws an infrared-ray image by display unit 10 by way of amplifier 9. The generated signal of transmitter circuit system 11 commands that the visual field of unit 2 is changed over to the reference light source.
