    摘要： Excitation electrodes are respectively affixed to central portions of both surfaces of a long plate-shaped AT-cut crystal resonator, the central portion starts a thickness shear oscillation in the length direction of the crystal resonator when an electric signal is applied to the central portion of the crystal resonator through the excitation electrodes. And, channel-shaped, half-circular-shaped, or trapezoid grooves in cross-section are respectively formed in the plate width direction on middle portions between the center portion and end portions of the crystal resonator. These grooves are formed so as to be symmetrical with respect to a thicknesswise central position of the crystal resonator through a well-known etching technique such as photo-etching and the like.

    摘要： An analog to digital convertor for converting mechanical motion to an electric digital signal which includes a code plate carrying gray codes for measuring displacement, codes for parity bits and parity check control bits and gray code reading means and decoder therefore wherein the parity bits detect the occurrence of a readout error and producing a warning signal while the parity check control bits detect an incorrect parity check caused by errors in the sensing operation such as dirt, dust, or damaged sensing elements, and produces a second warning signal, a memory for temporarily storing the output of the decoder and circuitry inter-connected with the memory and decoder to produce a third warning signal when the difference between the outputs of the memory and the decoder is greater than a predetermined value, circuitry for producing a first error signal when only the second warning signal is present and a second error signal when at least the first and third warning signals are present.
