摘要： Current mirror circuits that are parts of a first circuit and a second circuit, respectively, allow the same constant current to flow through the input side and the output side. Therefore, the base-emitter voltages of transistors Tr1 and Tr4, which tend to vary due to a temperature variation, can be set identical and hence can cancel out each other sufficiently. The same is true of the base-emitter voltages of transistors Tr5 and Tr8. Therefore, an input signal can be converted by a function having reference voltages as change points without being affected by temperature. Desired function circuits can be obtained by combining first circuits and second circuits in various manners.

摘要： A pair of electrodes are formed on the front surface and the rear surface of each vibrator in a longitudinal direction, and dielectric polarization is performed in the direction from the front surface to the rear surface. When I/V converters constituted by operational amplifiers are connected to electrodes of the middle vibrator, the detection electrodes can be grounded to a reference potential Vref through the imaginary short circuits of the I/V converters, so that a gyroscope can be vibrated without a conventional ground electrode. Therefore, the number of electrodes of the vibrators can be reduced, and an interval size between the drive electrodes or between the detection electrodes can be assured. For this reason, sufficient dielectric polarization can be performed when a high voltage is applied.

摘要： A driving signal is provided to six electrodes (driving electrodes) on one of the surfaces of each of three vibration legs of a three-pronged tuning-fork-type piezoelectric oscillator. Two output electrodes from among six electrodes (output electrodes) on the other surface thereof are connected to two current-to-voltage conversion devices, respectively. Since the two output electrodes are imaginarily short-circuited by the current-to-voltage conversion devices, there is no need to provide a ground electrode between the output electrodes. This makes it possible to simplify an electrode manufacturing process.

摘要： Two current outputs are converted into voltage outputs by I/V converters, and further converted into digital outputs D1 and D2 by binarizing circuits. The outputs are added by an adder in a phase shifter, and converted into an output like a triangular wave by an integrator. The output like a triangular wave is compared with a reference in a binarizing circuit and, therefore, it is possible to shift the phase from the median of the phase differential between the two signals by 90 deg with high precision.

摘要： When output signal of an oscillator are binarized by binarization means, a timing signal for driving a sequence controller for controlling a correction portion is rested temporarily. The process for overwriting the contents of an E2ROM of the correction portion side with an RAM is rested temporarily. This can prevent noise product at the overwriting timing. Binary signals after binarization can be prevented from being varied. The oscillator can be driven stably so as to give an angular speed output with high accuracy.
