Title: Optical system driver
Inventor: MIYAJIMA GIICHI
IPC: G11B7/09
Filed: 1986-03-31
Abstract: PURPOSE:To attain the support of tracking/focus with high accuracy by providing a pillar elastic member to a neutral point support mechanism and fixing the end of the elastic member to the base and optical system support so that the center axis of the elastic member is made coincident with the center axis of a bearing and a support shaft. CONSTITUTION:When an objective lens support 2 is driven by an angle theta by the tracking drive, the neutral point support rubber 7 is in torsional deformation in the rotation direction attended with the deformation of a slit part 7a. In this case, a restoration force F4 is exerted to the neutral point support rubber 7 to restore the objective lens holder 2 in the home position. Since the restoration force F4 is caused by the torsional deformation of the entire neutral point support rubber 7, the force becomes a torque to the rubber 7 with respect to the center axis. Thus, the center axis of the rubber 7 is coincident with the center axis of the objective lens holder 2, that is, the center axis of the bearing 6 and coincident with the center axis of the support shaft 8, then no eccentricity of the bearing 6 and the support shaft 8 is caused and the very stable tracking control is attained.

Title: Feedback amplifier
Inventor: TANAKA KOUICHI
IPC: H03F1/00
Filed: 1979-06-07
Abstract: PURPOSE:To prevent the generation of a transient noise by providing a DC stopping capacitor with charging or discharging transistors differing in emitter area and by making them respond to transient voltage changes in voltage application to a feedback amplifier or its break. CONSTITUTION:In electric power feed, DC stopping input capacitor C1 and feedback capacitor C2 are both charged momentarily by transistor Q4 and transistor Q5 via input terminal 1 and feedback terminal 2 respectively and emitter area S5 of transistor Q5 is set double than emitter area S4 of transistor Q4. A difference in emitter-base forward voltage between both the transistors due to a difference in emitter area is about 18mV at the normal temperature being in proportion to the logarithm of the area ratio. The time until the stationary state is set is therefore momentary and potentials V1 and V2 at terminals 1 and 2 bear relation V2>V1, so that no pop sound will be made. Consequently, a transient noise can easily be prevented from appearing.

Title: Semiconductor laser driving circuit

IPC: G11B7/125
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To drive a semiconductor laser by a lower power source voltage than a voltage in the forward direction of the semiconductor laser without using an inductance element by providing two switch circuits and a pulse width modulating circuit. SOLUTION: A changeover of the charge/discharge of a capacitor C1 is performed by the switch circuits 1 and 2, and an emitting light quantity of the semiconductor laser 3 is detected by a photodetector 4. The switch circuits 1 and 2 are controlled by the pulse width modulating circuit 5 based on a detecting current of the photodetector 4. Then, the capacitor C1 is connected with a power source 11 in series by the switch circuits 1 and 2, and a voltage charged in the capacitor C1 is added to a voltage Vcc of the power source 11, so as to drive the semiconductor laser 3. Thus, since the capacitor C1 is discharged by one switch circuit, and at this time, the voltage charged in this capacitor is added to the power source voltage Vcc, the higher voltage than the power source voltage Vcc can be obtained.  Consequently, the semiconductor laser 3 can be driven by the lower power source voltage than the voltage in the forward direction of the semiconductor laser 3.

CONSTITUTION:Assuming that eight bits of information can be stored in a data register 3b, and after a counter circuit 6 counts eight clock signals ch, a control circuit 7 generates a write control signal, and interrupts a write operation to a memory cell array 3a, and after completing the transfer of the bit of information of the next line from the 3a to the data register 3b, a control is performed so as to restart the write operation of an input signal to the memory cell array 3a. Since a period until the content of the next line arrives, is a non-display period including a displaying synchronizing signal R part, the content from the memory cell array 3a is transferred to the register 3b in the period. After the completion of the transfer operation, by switching a switch ll so as to set an output from the second storage element as an input to the memory cell array 3a, it is possible to prevent the omission of a bit of input information due to thc transfer operation, and simultaneously, the transfer of the bit of information to the resister 3b as an output buffer, can be performed exactly.
