Title: Track searching method for disk reproducing device
Inventor: HARA MASAYUKI
IPC: G11B27/10
Filed: 1988-03-09
Abstract: PURPOSE:To search tracks surely and at a high speed by repeating reading actions only when a read track number is different from that read in the preceding time. CONSTITUTION:When the track numbers and the information on the playing time are read, these reading actions are repeated to decide whether the target track position is acquired or not only in case a read track number is not coincident with that read in the preceding time. While a deciding process is carried out with no repetition of said reading actions when coincidence is obtained between said both track numbers. Thus the speed of track searching is increased compared with a method where the track numbers and the information on the playing time are always read twice for each track jump.

Title: Automatic tracking method of astronomical telescope
Inventor: KASHIWAKURA HISAMORI
IPC: G02B23/16
Filed: 1984-03-26
Abstract: PURPOSE:To track automatically a star chart even with a normal astronomical telescope through easy operation by performing parabolic approximate calculation by a microcomputer on the basis of position data obtained by observing the movement of a target twice within a preset specific time. CONSTITUTION:When a step switch is pressed again, the shutter drive output of a camera is outputted to release the shutter and also enters a tracking period PB, and the state is displayed on a lamp; and the arithmetic circuit of the computer performs arithmetic from this point of time at every time DELTAt and outputs pulses of the arithmetic results. Namely, the movement extents (speed and direction) of the telescope in an (x) and a (y) direction after the start of the tracking are calculated from the difference between the 1st and the 2nd counted numbers of pulses and the 2nd counted number of pulses, then while said arithmetic is repeated every time DELTAt, the telescope is driven with generated driving pulses. In such a case, the driving pulses are generated at the period obtained by dividing said number of arithmetic pulses by the set time DELTAt, so the telescope is driven at a constant speed during the period to move on a straight line extremely close to the actual track P of the target.

Title: Semiconductor photo amplifying system
Inventor: TABUCHI HARUHIKO
IPC: H01S5/00
Filed: 1987-03-12
Abstract: PURPOSE:To prevent the mutual interference between an oscillator and an amplifier, and realize a stable photo amplification, by interrupting the oscillator during the incidence period of a backward light from the amplifier, and interrupting the amplifier, on the contrary, during a period in which it is possible that a light from the amplifier may exert a bad influence upon the oscillator. CONSTITUTION:A timing controller 7 having a function to turn on and off the operation of an oscillator 1 and an amplifier 3 is provided. The oscillator 1 is operated so as to have a pause state while a backward light 5 from the amplifier 3 enters the oscillator 1. The amplifier 3 is operated so as to have a pause state while a period in which the backward light 5 output from the amplifier 3 reaches the oscillator 1 coincides with a period is which the oscillator 1 is in the active state. Therefore, while the oscillator 1 is in the active state, the backward light 5 from the amplifier 3 does not enter the oscillator 1, and so the interference between the output light 4 from the oscillator 1 and the backward light 5 from the amplifier 3 does not generate. Thereby, photo amplification of low noise and small distortion is enabled.

Title: Amplitude limiting oscillator circuit
Inventor: KUSAKABE HIROMI
IPC: H03B5/12
Filed: 1978-05-15
Abstract: PURPOSE:To ensure the stable operation with a small amplitude for the oscillator circuit by connecting one of the differential paired transistors featuring the different balancing states to each other to the positive feedback loop and then connecting the other transistor to the negative feedback loop respectively. CONSTITUTION:One side of differential paired transistors TRQ1 and Q2 plus TRQ3 and Q4 are connected to form the positive feedback loop, and the other side are connected to form the negative feedback loop respectively. At the same time, the emitter area ratio is set to 1:N (N>1) between TRQ3 and Q4. Thus, the emitter current features 1:N with a lower gain obtained than the differential amplifier featuring the equal emitter current. In other words, the gain becomes maximum when the base bias features the unbalanced state with the equal emitter current as shown by broken-line curve G2. Accordingly, the composite gain features solid-line curve G3, obtaining a stable amplitude limiting oscillator featuring a small amplitude. Furthermore, the oscillation width can be set freely by selecting the value of N.

Title: Device for preventing electrostatic breakdown
Inventor: NEGISHI KEIICHI
IPC: H01T4/10
Filed: 1990-03-08
Abstract: PURPOSE:To prevent electric discharge between a discharge terminal and one conductive pattern for discharge terminals by forming a non-conductive thick printed pattern on a non-conductive base between the conductive pattern in proximity to the other conductive pattern and the other conductive pattern. CONSTITUTION:When static electricity with high voltage is applied to a device from the outside via e.g. a lead wire connected to a conductive pattern 5, electric discharge occurs between the conductive pattern 5 and a discharge terminal pattern 9 formed in a ground pattern 3. By the discharge static electricity with high voltage is discharged from the conductive pattern 5 to the ground pattern 3 so that the voltage of the conductive pattern 5 is reduced. Because the voltage of the conductive pattern 5 is transmitted to an internal circuit through a resistance 17, the voltage is further reduced by the resistance 17 and the input impedance of the internal circuit, etc. Therefore static electricity with high voltage is not directly applied to the input end of the internal circuit and breakdown of the internal circuit is precisely prevented.

Filed: 1982-04-06
Abstract: PURPOSE:To eliminate a special step for fixing between stator iron plates by temporarily fixing the iron plates via coil section and slot insulating paper, and clamping them via clamping bolts in case of mounting a flange. CONSTITUTION:Stator iron plates 1 are not fixed to each other at all, but temporarily fixed via coil section 8 and slot insulating paper 9 which are inserted into a slot 6. When a motor stator is clamped via a clamping bolt 10 to a flange 7 at this time, the bolt 10 is clamped while aligning the iron plates 1 to form an air gap between a motor rotor and the stator. According to this method, a special tool for clamping the ion plates is not necessary, thereby providing inexpensive motor stator.
