Title: Clock pulse generating circuit
Inventor: ITOI TETSUO
IPC: G11B20/10
Filed: 1981-11-30
Abstract: PURPOSE:To obtain assuredly the clock pulse synchronous with the external signal at all times, by varying the frequency of the clock pulse which is internally oscillated in response the phase change of the reproduced signal which is used as the external input signal. CONSTITUTION:The reproduced signal A synchronous with the clock pulse CP delivered from a voltage control type variable oscillator 8 is supplied to the 1st differentiating circuit 1, and the differential output signal B of positive polarity is produced. At the same time, the differential signal D of positive polarity which has a slight delay of phase compared with the signal A is delivered from the 2nd differentiating circuit 3. The signals B and D are fetched into the latch circuits 4 and 5 respectively during the rise of the pulse CP, and the output signals E and F having a coincidence in the H period are produced from the circuits 4 and 5 respectively. If the signal A has a delay of phase compared with the pulse CP, the signals B and D are set at H and L respectively during the rise of the CP. Therefore the signal E is set at H during the rise of the CP, while the signal F is kept at L. Thus the output signal passed through a differential circuit 6 and an LPF7 is lowered less than the reference value, and the oscillating frequency of the oscillator 8 is lowered.

Abstract: PROBLEM TO BE SOLVED: To obtain a green compact having the same compression ratio and the uniformized density distribution by filling powder into a die, using a recessed upper punch after compacting the upper surface of the powder while bulking up as a projected state and press-compacting. SOLUTION: The powder 5 for sintering the green compact is naturally filled into the compacting space 2 in the die 1.
