摘要： In an electronic caliper, a detecting circuit 112 detects displacement of a grid with respect to a scale, on the basis of a signal from a transducer 110. A CPU 114 displays the detected position on a display device 124. The CPU 114 performs error detection on the transducer, only when the relative speed of the grid with respect the scale is zero, or becomes equal to or smaller than a predetermined value. Since error detection is performed only at a predetermined timing, power consumption can be reduced.

摘要： Disclosed is a variable capacitance type encoder for measuring the length of an object to be measured on the basis of the amount of a probe which is brought into contact with the object. The amount of the movement of the probe is detected by the variation of electrostatic capacity between a rotary disc which is secured to the shaft, e.g., threaded shaft of the probe, and fixed plates which are secured to a baseplate so as to be opposed to the rotary disc. Two fixed plates are opposed to the rotary disc, and at least one fixed plate is provided with first and second transmitting electrodes composed of a pluarlity of electrode elements to which voltages of different phases are applied and which are annularly arranged at regular intervals in the circumferential direction of the fixed plate. The phase difference between the voltages which are applied to both transmitting electrodes is 180.degree.. On the other hand, the rotary disc is provided with first and second receiving electrodes for receiving signals of a common phase by electrostatic coupling with both transmitting electrodes. Each fixed plate is provided with an output electrode which electrostatically couples with the respective receiving electrode for fetching a signal through electrostatic coupling.

摘要： The invention is to provide a gas laser in which a discharge tube of a double-tube construction comprising a inner tube and an outer tube of a relatively large diameter is employed, a tubular discharge space filled with a gas mixture is formed between the inner tube and the outer tube, a gas mixture cooling passage is formed within the discharge space, and a pair of mirror groups are disposed at both ends of the discharge space, each mirror group comprising a plurality of mirrors arranged in the circumferential direction. The respective mirrors are arranged in such a manner that a laser beam is reflected by the mirrors to go and return in the discharge space several times and each path of the laser beam between the corresponding two mirrors obliquely intersects the central axis of the discharge space. Thus, it is possible to obtain a laser beam in single mode with a single discharge tube without the need of enlarging a length of the tube and also to reduce a pressure loss of the gas mixture within the discharge space.
