Filed: 1994-04-28
Abstract: PURPOSE:To accelerate large amplitude response by connecting a switch circuit shifting sample operation and hold operation based on a mode switch output current of a switch drive circuit to the prestage of a hold capacitor. CONSTITUTION:When a voltage so as to become a sample operation state is applied to a control terminal 17, a current flows from the output terminal OUT1 to the 0UT2 side of the switch drive circuit 18, and transistors Q1, Q2, Q4, Q5 are biassed forward, and the Q3, Q6 are biassed backward. At thus time, an output voltage of a switch circuit 16 is controlled by the voltage of an input terminal 11, and the voltage of the terminal 11 is transmitted to the output terminal 14. The charge/discharge of the hold capacitor 13 is performed by the Q2, Q5. On the other hand, when the voltage so as to become a hold operation state is applied to the terminal 17, the current flows from the OUT2 to the OUT1 of the circuit 18, and the output of the circuit 16 becomes high impedance, and the voltage of the terminal 14 becomes the voltage held to the capacitor 13. Thus, the response is accelerated without increasing power consumption.

Abstract: PURPOSE:To make it possible to accurately detect the position of the hole of an article to be detected, by irradiating the surface of an article to be detected with the light from a light source through a light emitting optical fiber and detecting the reflected light from the article to be detected of the irradiated light. CONSTITUTION:A detector 1, constituted by a method wherein the leading end parts of a light emitting optical fiber 2 and a light receiving optical fiber 3 are mutually arranged in a concentric form and integrally bundled, is provided to irradiate the surface of an article W to be detected with the light from a light emitting diode 5 being a light source through the light emitting optical fiber 2. The reflected light from the surface of the article W to be detected of the irradiated light is detected through the light receiving optical fiber 3 and the shift of the detector 1 from a hole position of the detector 1 is judged on the basis of the irregularity of the reflected light to move the detector 1 to the hole position. By this method, because the irradiation angle of irradiated light from the light emitting fiber 2 can be always kept constant, the hole position of the article to be detected can be stably and accurately detected.
