Title: Miniature type quartz oscillator in contour vibration mode
Inventor: SATOU HIROCHIKA
IPC: H03H9/19
Filed: 1979-06-07
Abstract: PURPOSE:To lessen an influence of a cut angle on frequency-temperature characteristics by fixing the cut angle and size of a contour-vibration-mode miniature quartz oscillator under specific conditions. CONSTITUTION:With cut angle theta matched properly to side ratio (r), variation dalpha/dtheta in frequency-primary temperature coefficient alpha with cut angle theta becomes extremely small while the frequency-primary temperature coefficient becomes nearly zero. Therefore, when the size of vibrator 11 is fixed, for example with W=1.4mm. and L-1.5mm., and W1=0.9mm. and L1=2.16 (side ratio r=0.94), frequency-temperature characteristics show a value, nearly equal to zero, at cut angle phi=-45 deg. and theta=54-56 deg.. Consequently, the contour-vibration-mode miniature oscillator can easily be obtained which exerts a small influence of the cut angle on the frequency- temperature characteristics.

Filed: 1986-04-01
Abstract: PURPOSE:To enable a motion even for a device with comparatively slow processing by taking the absolute value of the digital signal inputted or outputted successively at high speed holding the maximum value at least for a fixed length of time by performing a comparison of the magnitude within the fixed time and by discriminating and displaying the level of the held data. CONSTITUTION:The data conversion to absolute value is performed by reversing the PCM data which become a negative value in an absolute value converting circuit 2 due to the PCM data outputted from a digital signal processing circuit 1 having positive and negative values (the most significant bit shows the positive and negative). The large and small comparison of the data inputted on each sampling period is performed in a level large and small comparator 3 and the holding value of a data holding circuit 4 is rewritten by detecting the maximum value of within a fixed time. The data holding circuit 4 always continues to hold the data rewritten at fixed time intervals until being rewritten. The reading of the data is performed at faster cycle than the data update intervals on the data holding circuit 4 in a data level display discriminating circuit 5.

Filed: 1989-03-24
Abstract: PURPOSE:To prevent the deterioration of characteristics due to mutual intervention between analog-digital circuits by branching a wiring for supplying a semiconductor substrate with potential from a wiring for supplying power for operating the circuits. CONSTITUTION:A wiring 18 is led out of a terminal 4 for external connection, and low potential is fed to a first analog circuit 14, a second analog circuit 15, a first digital circuit 16 and a second digital circuit 17. The wiring 18 and a substrate 1 are brought into contact in these circuits 14-17, thus supplying the semiconductor substrate 1 with potential. Since the wiring 18 is not used for objects except a contact with the semiconductor substrate 1, currents are not made to flow through the wiring 18, thus generating no potential difference in the wiring 18. Consequently, no potential difference is generated in the semiconductor substrate 1. Accordingly, the deterioration of characteristics due to mutual intervention between the circuits can be prevented.
