摘要： An object of the present invention is to avoid the instability of frequency measurement caused by spatial connection between quartz sensor adjacent to each other when a plurality of quartz sensors including a quartz resonator which varies the national frequency due to adsorption of an object to be detected. As a concrete means for solving the problem is to provide a common measuring unit 200 to measure the variation in frequency to each oscillation circuit 51 corresponding to each quartz sensor 1 so as to switchover and connect in turn, and as for the oscillation circuits 51 excepting the oscillation circuits 51 connected to the measuring unit 200 by the switches 52 serving as the load switchover unit, the load value on the output side of the oscillation circuit 51 included (relating to the measurement) in the channels connected to the measuring unit 200 and the load value on the output side of the standby oscillation circuits 51 are made different from each other, so that the respective oscillating frequencies are forcibly separated from each other.

摘要： A VCO driving circuit and a frequency synthesizer wherein the impedance viewed from a VCO control terminal is reduced to prevent the VCO phase noise characteristic from degrading. A VCO driving circuit and a frequency synthesizer having the VCO driving circuit, which comprises a coarse adjustment DAC (4) that receives a digital data, which has a coarse adjustment frequency, to output an analog signal; a fine adjustment DAC (6) that receives a digital data, which has a fine adjustment frequency, to output an analog signal; a low response speed LPF (5) that removes noise from the output signal from the coarse adjustment DAC (4) and then provides the resultant signal as an input to a VCO control terminal; a high response speed LPF (7) that converts the output signal from the fine adjustment DAC (6) to a voltage, thereby smoothing the signal; a resistor (R6) that connects an input stage of the LPF (5) to that of the LPF (7); and a capacitor (C8) used for providing a capacitive coupling such that the output of the LPF (7) is added to that of the LPF (5).

摘要： A quartz crystal vibrator has a vibrator element which includes a quartz crystal plate having obverse and reverse sides. A first excitation electrode is provided on the obverse side of the quartz crystal plate at the central portion thereof, and a first connecting electrode extends radially from the first excitation on the obverse side. A first supporting electrode is connected to the first connecting electrode and is provided fragmentarily along the entire circumference of the quartz crystal plate on the obverse side thereof. A second excitation electrode is provided on the reverse side of the quartz crystal plate at the central portion thereof at a position underlying the first excitation electrode, and a second connecting electrode extends radially from the second excitation electrode on the reverse side. A second supporting electrode is connected to the second connecting electrode and is provided fragmentarily over substantially all of a circular ring-like region located inwardly of the circumference of the quartz crystal plate on the reverse side, so as not to overlap the first supporting electrode. A first terminal pin is connected to the first supporting electrode at any point thereon, and a second terminal pin is connected to the second supporting electrode at any point thereon.

摘要： A thickness shear quartz crystal oscillator has two major surfaces which extend in the direction the of X axis of the crystal and which are 5mm to 10mm long. X-Z plane defined by the X axis and Z axis of the crystal is rotated about the X axis by 35 DEG 08' to 35 DEG 16' so that the major surfaces are parallel to an X-Z' plane defined by the X axis and an imaginary Z' axis inclined to the Z axis at 35 DEG 08' to 35 DEG 16'. One of the major surfaces is displaced in the direction of the Z' axis to thereby cause the side faces of the oscillator to incline at an angle of 4 DEG to 6 DEG .
