Title: Pressure measuring device
Inventor: SUTANREE HATSUSERU
IPC: G01L23/18
Filed: 1979-12-19
Abstract: Dynamic pressure fluctuations are sensed remotely by means of a transducer 7 communicating through a small hole in a wall of a duct 1 formed by a length of tube closed at one end 2 and open at its other end 3 to a space in which pressure is to be measured (for example, a high temperature region in a gas turbine engine). To ensure a resonance-free aperiodic frequency response characteristic, enabling dynamic pressure variations to be detected up to frequencies of several kHz, the hole is arranged closer to the open end than the closed end and an attenuation insert in the form of a rod or tube may be located adjacent the closed end. The transducer which may include an electrical strain gauge is protected from high temperature or other hostile conditions at the sensing point. <IMAGE>

Filed: 1988-07-05
Abstract: PURPOSE:To keep a cable from being damaged by maintaining electrostatic chuck function for a certain time even though a power source cable is cut off and inserting the above cable in an electron beam exposure device after cutting off it when a wafer is held by electrostatic chuck and is inserted in the above exposure device. CONSTITUTION:A wafer holder is composed of; a base plate 2; a keep plate 4; wiring parts 6 and 6'; and terminals 7 and 7'. The wafer holder houses a capacitor 9 in it. Both poles of the capacitor 9 are connected to the wiring parts 6 and 6'. Once a wafer 3 is set in the wafer holder and a power source cable is connected, the wafer 3 is attracted statically and simultaneously, the capacitor 9 is charged. Even if the power source cable is cut off for the movement of the holder, voltage is impressed between a metal plate of the base plate 2 or a metal wire 1 and the water 3 by the capacitor 9. As a result, electrostatic chuck function is maintained until discharge of the capacitor 9 comes to an end. Such a state of the power source cable keeps the cable from being damaged.
