Patent JP-S5952406-A (JP)
Title: Jitter compensating circuit
Inventor: FURUICHI TOKIKATSU
IPC: G11B20/22
Filed: 1982-09-16
Abstract: PURPOSE:To obtain a stable reference voltage without cutting off a transistor (TR) by flowing a current from the emitter of a reference voltage output circuit TR to a complementary current amplifying circuit constituting an inverting amplifying circuit in the jitter compensating circuit of a video disk player. CONSTITUTION:The output-side point D of the complementary current amplifying circuit (Q3, Q4) and the emitter of the TRQ5 are connected together through a resistance R7. For example, when the voltage at a point A is higher than the reference voltage Vref, the voltage at the point D is lower than the reference voltage Vref, so currents flowing through resistances R2 and R1, and R4 and R5 flow to a TRQ4 through a resistance R7, thereby eliminating the influence of variation in reference voltage Vref. When the voltage at the point A is lower than the reference voltage Vref, the voltage at the point D is higher than the reference voltage Vref, so currents flow through the resistance R7, and resistances R1 and R2, and R5 and R6, so variation in reference voltage Vref is eliminated. Therefore, the variation in reference voltage Vref depends upon a small signal part, which is small, so that the reference voltage Vref does not vary.

Title: Laser radiation control circuit for optical disk device
Inventor: TAKEDA KATSUMI
IPC: G11B7/0045
Filed: 1986-07-09
Abstract: PURPOSE:To omit switching of laser power for each track in case data across plural tracks are continuously recorded on plural spiral tracks, by recording data with the recording power of a fixed level over all tracks including the start one through the final one. CONSTITUTION:A microcomputer 3 serving as a recording power setting means is connected to the input side of a D/A converter 4. When a recording track address is supplied to the computer 3 from an external controller, the computer 3 delivers a recording start address to the converter 4 and at the same time sets the recording power of a fixed level to record all tracks including the start one through the final one. The converter 4 converts the digital output received from the computer 3 into analog signals to actuate a laser power control circuit 5. Thus the recording power delivered from the computer 3 is set and the recording data supplied to a laser driving circuit 6 via a laser 7 are recorded on a disk 1. Thus it is not required to switch the recording power for each track and therefore no spike noise is produced.

Abstract: PURPOSE:To prevent generation of shocks, by slipping a center differential gear device so that the differential rotation of a center differential gear or the relative rotation of front and rear propeller shafts are set at a constant value in order to prevent the differential rotation from dropping to zero. CONSTITUTION:The rotational speeds of front and rear propeller shafts 5A, 5B which are coupled with each other by means of a center differential gear 8 are detected by sensors 11 provided to both shafts, respectively, and thus obtained detection signals are delivered to a vehicle condition detecting means 14 which detects slipping conditions of front and rear wheels and delivers an operating signal to an actuator controlling means 15. That is, when the difference between the rotational speeds exceeds a predetermined value, current running through a solenoid in a lock actuator 13 in an electromagnetic multi-disc type clutch 12 is increased to reduce the difference in rotational speed. Meanwhile, when the difference in rotational speed is lower than the predetermined value, the current running through the solenoid is decreased to increase the difference in rotational speed.

Title: Gain control circuit
Inventor: IDE TATSUKI
IPC: H03G1/00
Filed: 1979-12-10
Abstract: PURPOSE:To make the control sensitivity constant to the control signal, by the gain control with the same control signal, through a series connection of two sets of differential transistor pairs. CONSTITUTION:After the signal S1 input from the base of a transistor (TR)T11 is converted into a signal current at TRT11, it is divided according to the control signal VF and the reference bias VE for the DC potential, through the 1st differential transistor pair 31. One of the divided currents flows to a load resistor RL through the current division at the signal VF by the 2nd differential transistor pair 32 similarly. The signal current flowing to the resistor RL becomes the output signal of gain control. Thus, by connecting two sets of differential TRs 31, 32 in series and performing the gain control with the same control signal at the same time, the control sensitivity to the control signal is made constant.
