Title: Oscillator
Inventor: KINUGASA TOSHIRO
IPC: H03L7/06
Filed: 1987-02-05
Abstract: PURPOSE:To remove the influence of frequency dividing noise by setting up n (three or more) phase ranges every m times the output signal of a VCO and detecting the phase transition of the output signal of the VCO from a reference signal by using the phase ranges to control oscillation frequency. CONSTITUTION:A reference signal A is inputted from a terminal to a phase transition detector 2. A phase difference former 6 having a period corresponding to 1/m times the output of the VCO forms n signals whose phases are respectively different every 1/n times the period of the output signals as comparing signals and an interval between successive leading edges is set up as a phase range. A phase transition detector 2 detects the phase range including the decay of the reference signal, decides the advance/delay from the rise of an output B from the VCO 4 and generates a signal D having a different level on the basis of the decision. An LPF 3 receives the signal D and forms a control signal E for the VCO 4. In such constitution, the comparing signal can be set up to a sufficiently high frequency level as compared with that of the reference signal A and the influence of frequency dividing noise can be removed.

According to this method, various types of printed wiring boards can be handled only by changing the positions at which the heat-resistant pressure-sensitive adhesive is applied. Further, since the printed wiring board is fixed by the adhesive, it is prevented from being fallen down or lifting from the pallet.
