摘要:
A position detector having a magnetic sensor for measuring linear or angular displacement, or detecting a position of a body without contact thereto. The detector has a closed circuit including magnets and yokes. The magnetic leakage flux which emanates from the inside surfaces of the yokes is utilized to detect the position of the body. The magnetic sensor is transferred along the inside surfaces of the yokes by a transferring circuit, which senses the magnetic field intensity of the leakage flux distributed thereon. This enables the detector to have a longer measuring range than that of a prior art detectors. An output signal is stable due to the shielding effect of the yokes. The magnetic closed circuit has many magnetic and mechanical configurations. For example, for the magnet, a permanent magnet and an electromagnet can be used. Further, improvements are proposed for enhancing the linearity of the output signal voltage with respect to the transferring distance of the sensing element and for compensating the offset drift of an amplifier or changing the coercive force of permanent magnets.

摘要:
A piezoelectric resonator which resonates in thickness shear mode. The piezoelectric resonator includes a strip shaped resonance chip made of an X-cut plate of lithium tantalate crystal and having a rectangular cross-section. Electrodes are formed at the center portion with respect to the longitudinal direction of the resonance chip on each of two X-plane surfaces. The width of the electrodes is equal to the width of the resonance chip. The longitudinal direction of the resonance chip inclines with respect to the Y-axis by an angle of 50.degree..+-.2' in the clockwise direction in the X-plane so as to make the longitudinal direction of the resonance chip coincide with the displacement direction of primary oscillation of the crystal. Optimal ratios of the dimensions of the resonance chip and terminal connectors at the ends of the resonance chip are given to reduce spurious response. The temperature characteristic is optimized by selecting rotation angles about the Y-and Z-axes in relation to the amount of trapped energy.
