Title: Driving circuit of yig oscillator
Inventor: OTSUKA TOSHIMASA
IPC: H03B5/18
Filed: 1988-06-03
Abstract: PURPOSE:To prevent the saturation of a driving element and to considerably improve the responsibility by constituting the driving circuit of an oscillator in such a way that it supplies a high voltage to a main coil when a driving current is suddenly increased. CONSTITUTION:When an input signal with respect to a transistor TRQ2 suddenly rises at a prescribed time, the emitter voltage of TRQ2 rises and a large differential pulse on a minus side is outputted from a differential circuit 10. When the pulse exceeds a reference voltage Vr, a detection signal in an 'L' level is outputted from the comparator 21 of a comparison circuit 20 to a power voltage switching circuit 30 and therefore, TRQ3 is turned on and a higher voltage V2 is supplied to the main coil L. Thus, TRQ2 does not reach a saturated state and the driving current almost follows the input signal, suddenly rises and reaches a prescribed current. When the voltage of the differential pulse comes below the reference voltage Vr, the output of the circuit 20 returns to an 'H' level and power is supplied again by the power source of a voltage V1. The oscillation frequency of the oscillator changes in accordance with the input signal.

Title: Thin plate piezoelectric oscillator
Inventor: KIZAKI SHIGERU
IPC: H03H9/21
Filed: 1977-11-17
Abstract: PURPOSE:To secure a uniform shape for the fracture surface as well as to realize an ultra-miniature size for the oscillator by forming the thin-thinkness part by giving the half-etching from the single surface of the bridge part of the oscillator bar which is supported and fixed to the piezoelectric substrate. CONSTITUTION:The oscillator is taken out of the etching solution in the course of the etching for its external shape processing, and an etching is given to at least single  surface of the thin film which is the masking component at the area of bridge 4. Then the piezoelectric substrate is put into the etching solution again to carry out the U-shaped half-etching. Thus, the area of bridge 4 is thinned. In such way, the fracture becomes easy since the piezoelectric component is thinned in terms of the oross-section slthough the area of bridge 4 features the same shape as conventional. As a result, a uniform shape is ensured for the fracture surface, and also an ultra-miniature size can be obtained for the oscillator as a whole.
