    摘要: An encoder device of the absolute position type for outputting a shift position or angle of rotation relative to the absolute position. The device comprises a code plate having first and second grid patterns wherein information is stored as 1 or 0 in a periodic manner at pitches slightly different from each other; first and second sensory arrays for detecting the first and second grid patterns; driving means for driving the sensors relative to the grid patterns and for obtaining an alternating signal from each array; and computation means for measuring the phase angle of the alternating signal from each array, and the phase angle difference therebetween and for calculating the position using such phase angles. Advantageously, the invention is suitable for miniaturization due to its simplicity, relaibility, and efficiency.

    摘要: A quartz thermometer adapted to measure the ambient temperature through detection of a change in the resonance frequency of a quartz resonator due to change in the temperature, wherein a quartz wafer of 0.02 to 0.2 mm thickness is cut from a region of a quartz within -30.degree. to -70.degree. in terms of rotation angle about the X axis of the quartz thereby to form a quart resonator within a range of between -15.degree. to +15.degree. in terms of angle of rotation about the Z' axis within the plane of the quartz wafer; and wherein thin metallic films are formed on the surfaces of the resonator to serve as exciting electrodes. The resonator and electrodes are produced by photolithography and anisotropic quartz etching processes. The resulting quartz thermometer has a large first order temperature coefficient of frequency.
