Abstract: PURPOSE:To make a detector compact and to detect the displacement of a moving body highly accurately, by providing an auxiliary electrode, which cancels one of transmitted noise and roundabout noise, at the back surface of a fixed plate, and canceling the noise mixed into a receiving electrode from a wiring pattern. CONSTITUTION:Transmitted noise, which is mixed into an receiving electrode 14 from a pattern electric path 22a that is most closely located to the receiving electrode 14, is canceled by a correcting signal from an auxiliary electrode 26. The signal is induced based on a signal, whose phase is reverse with respect to the transmitted noise, by a transmitting electrode 12-2. Approximately the total amount of the transmitted noise mixed into the receiving electrode 14 from a wiring pattern 22 can be canceled. An AC voltage having the phase of 180 degrees, is applied to a transmitting electrode 12-3. An auxiliary electrode, which is conducted to the receiving electrode 14, is provided at the back surface of the electrode 12-3. Noise, which is mixed from a pattern electric path 22b that conducts an AC voltage of 0 degree, can be effectively canceled by a correcting signal induced by the transmitting electrode 12-3. In this way, approximately the total amount of the roundabout noises, which is mixed along the surface of a fixed plate 10 from the wiring pattern 10, can be effectively canceled.

Abstract: PURPOSE: To achieve the miniaturization of the lighting device and achieve the extension of its lamp life by alternately obtaining the signal of radiation point and the signal of junction point from luminance signals and lighting the lamp only when the signal of the junction point is obtained.  
     CONSTITUTION: A beam 110 is radiated to one surface of the object 105 to be lighted in a beam chamber 1 and is moved in the direction of the junction part by a motor 108. A television camera 101 includes the junction point 104 and radiation point 106 in its visual field and sweeps these in the direction rectangular to the junction part. A control unit 8 emits a lamp lighting signal 52' only during the period of junction point searching to a lighting device driving power source 11 so that the lighting device 102 is lighted up. At the same time, it emits a photo detecting sensitivity decreasing signal 52 to the camera. In the radiation point and junction point searching periods, the radiation point, junction point siganals 54, 55 are respectively obtained and the delay times from the sweep start signal 53 are obtained from counters 4, 14 and are stored in registers 5, 15.

Abstract: PURPOSE:To obtain a precision metal mold having uniform and stable metal mold cavity temperature and a low cost by filling particles in a section near a cavity, and forming at least one of a telescopic element as that with a temperature regulator in which heat medium can flow. CONSTITUTION:Resin to be filled in a cavity 1 is heated to a predetermined temperature, and introduced to the cavity 1 through a runner 3 and a gate 2. In order to rapidly uniformize the resin temperature in the cavity 1, a head medium heated in advance to a predetermined temperature is introduced by a circulation pump from a heat medium inlet 8 into a temperature regulator 10. Particles 11 are densely filled and sealed in the regulator 10, the medium fed into the regulator 10 is formed in a 3-dimensional passage without irregular flow to be brought into contact with the regulator 10 near the cavity 1, thereby smoothly heat exchanging. The medium is passed through a long passage to increase the surface area to be heat exchanged to be fully in contact with the surfaces of the particles to be sufficiently heat exchanged. Thus, the heat exchanging efficiency of the whole telescopic element is largely improved to shorten the time required to stabilize and uniformize the temperature of the whole element and to reduce the varying range of the temperatures of the sections of the element.
