IPC: G11B20/10
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To reproduce reproduced audio data with a fixed interval even when reproducing speed is variously changed by outputting the data while correcting the interval of the data so as to correct the change of the interval due to the change of the revolutional speed of an optical disk. SOLUTION: A system control circuit 15 calculates the controller variable needed for correcting the change of a the interval due to the change of the transfer rate of audio data to give the instruction of changing the interval to a key control circuit 16. That is, when the optical disk is reproduced by an S-fold speed, the circuit 15 calculates a controlled variable K/S to give the instruction of changing the interval to the key control circuit 6 so as to change the frequency of audio signal SA to K/S multiple. Thus, the circuit performs a correction so that a divided value S in which the changed transfer rate is divided by a standard transfer rate and a divided value 1/S in which the frequency of the audio signal at the time any interval correction is not performed is divided by the frequency of the corrected audio data have a constant relation.

IPC: G06F7/548
Filed: 1980-02-05
Abstract: PURPOSE:To make it possible to reduce the memory capacity by generating a sine function by use of the ROM whose phase range for storing the sine function has been made to 1/4 of one period. CONSTITUTION:When the input of l bits of the phase (x) (-pi<=x<pi) is input to the circuit of operation I, the phase is moved in parallel, it becomes -pi/2<=y< pi/2, and becomes 1/2 of the area of (x). Subsequently, when this phase is input to the circuit of operation II and is inverted partially, it becomes 0<=z<=pi/2, and becomes 1/2 of the area of (y). A since function can be obtained by reading it out from the ROM11 storing the sine function within the range which is ''0'' or more and smaller than pi/2, by use of said phase. When it is inverted again by the circuit of operation III, a desired sine function can be obtained. In this way, the memory capacity of the ROM11 can be reduced to 1/4.

Title: Voltage control oscillator
Inventor: SHIMADA GIICHI
IPC: H03K3/011
Filed: 1984-01-26
Abstract: PURPOSE:To stabilize the self-traveling oscillation frequency to the variance of the power supply voltage by using a capacitive element which delays the through rate to obtain the flat relation between the power supply boltage and the self- traveling oscillation frquency. CONSTITUTION:The 2nd capacitor C2 serving as a capacitive element is provided between an earth point and a juncture A between the base of a charging current control transistor TRQ4 and a conduction control TRQ9. Then the through rate of a volatege waveform is delayed at the point A to reduce the effect of the variance of the power supply voltage VCC to the charging time for the 1st capacitor C1 at a point B. Thus a charging/discharging circuit including the capacitor C1 performs its charging/discharing action as desired. As a result, the self-traveling oscillation frequency is always stabilized regardless of the variance of the voltage VCC.
