Title: Piezoelectric oscillation device
Inventor: ARAKI YOSHIAKI
IPC: H03B5/32
Filed: 1988-03-30
Abstract: PURPOSE:To improve the frequency stability and at the same time to reduce the size of a piezoelectric oscillation device by using the temperature correcting control signal which is set previously by the signal received from a temperature detector in response to an ambient temperature to change the temperature of a piezoelectric vibrator. CONSTITUTION:A memory circuit 5 transmits a correcting digital control signal stored in response to a digital signal to a D/A converter 4 by the signal obtained by converting an analog signal received from a temperature detector 7 in response to an ambient temperature into a digital code by an A/D converter 6. The converter 4 sends the analog control signal converted from a digital control signal to a temperature control circuit 21. The circuit 21 controls the heating value of a heating element 3 and changes the temperature of a piezoelectric vibrator 1 to keep a constant oscillation frequency. Thus a compact piezoelectric oscillation device is obtained with high stability of frequency.

IPC: H03K19/003
Filed: 1981-05-26
Abstract: PURPOSE:To improve a noise margin against a ground noise generated by a rush current, by providing a threshold value of an input circuit with hysteresis characteristics. CONSTITUTION:As input threshold value a high-level side VTH and a low-level side VTL are provided separately. When an input voltage VA increases, an output voltage VD holds itself at a high constant level through paths 10 and 11, but when the VA reaches the VTH, it drops to a low level through a path 12 and then reaches a path 13. When the VA drops, the VD holds itself at a low constant level through paths 13 and 14, but when the VA reaches the VTL, the VD rises to a high level side through a path 15. A noise margin is widened by the width of hysteresis characteristics, narmely, the difference between the  VTH and VTL. To obtain the characteristics, a diode is provided on the input  side, the level of the output side is shifted by the diode, then feedback is provided.
