Title: Pll circuit
Inventor: OKUBO FUYUKI
IPC: H04N5/44
Filed: 1992-05-14
Abstract: PURPOSE:To prevent miscounting by connecting a low pass filter(LPF) for removing a higher harmonic component from a voltage controlled oscillator(VCO) between the VCO and a prescaller. CONSTITUTION:This PLL circuit is provided with the VCO 11, the LPF 12, the prescaller (frequency-predivider) 13, a PLL synthesizer 14, a reference signal oscillator 15, a loop filter 16, and a microcomputer 72. Namely when the input sensitivity of the prescaller 13 is sufficiently high in the frequency band of a higher harmonic, miscounting may be occasionally generated. Thereby the LPF 12 for attenuating a higher harmonic component out of a signal formed by the oscillator 11 is inserted between the oscillator 11 and the prescaler 13. Miscounting can be prevented by attenuating the higher harmonic component out of the signal generated from the oscillator by means of the LPF 12.

Filed: 1989-05-16
Abstract: PURPOSE:To prevent a specimen to be etched from being contaminated by a method wherein the surface of a carbon sheet having many vent holes is covered with a pyrolyzed carbon film. CONSTITUTION:A pyrolyzed carbon film 5 is formed on the surface (including the inside of vent holes 4,...) of a carbon sheet 1. A film thickness (t) is formed to be 50mum; the film is highly dense and highly pure.
