Title: Sample holder in electron ray exposing device and the like
Inventor: TAMAI MAKOTO
IPC: H01L21/027
Filed: 1979-02-09
Abstract: PURPOSE: To improve the exposure accuracy by fixing a sample holder by the pressing force of an  elastic member, releasing and leading out the pressing force and removing a force applied to a  shifting mechanism at the time of sample exchange.  
     CONSTITUTION: At the time of exposure, metal fittings 15 are separated from a pipe 16, and the  interior of a vessel 13a is communicated with the interior of a sample chamber 1 to balance the  internal and external pressures of the vessel. A pressing member 8a presses a sample holder 6  against a receiving plate 5a through a projection 10a by a spring 11a to fix the sample holder 6 to  a movable member 2. After the exposure, when the movable member 2 moves to a predetermined  position, a bar 21 is driven 22, and metal fittings 15 are pressed against a pipe 16 and connected  thereto. By operating a valve 24b the vessel 13a is stretched by a gaseous pressure and the pressure of the holder 6 to the movable member 2 is released thereby to carry out the attachment and  detachment of the holder 6 to and from the movable member 2. After loading, the valve 24a is  operated to exhaust gas and the internal and external pressures of the vessel 13a are balanced to  fix the holder to the receiving plate, and the bar 21 is caused to descend and the pressing force of  the metal fittings is released to shift the movable member 2 to an exposure starting position.  According to this organization, no force is applied to the shifting mechanism, and therefore no  deviation is generated, thus the exposure accuracy being improved.

IPC: B65H5/06
Filed: 1983-01-31
Abstract: PURPOSE:To reliably adhere paper money to a read magnetic head by pushing aside a fluid in a cavity of a pinch roller to the peripheral portion of rotation by centrifugal force as the pinch roller is rotated at more than a fixed speed, thereby expanding a contact portion. CONSTITUTION:When paper money A is inserted in a read port J, a sensor 1 is adapted to detect it and send a detection signal D to a control portion 2. The control portion 2 sends out a start signal C to a driving portion 3, so that a motor M is started to drive a shaft S, thereby starting the rotation of a pinch roller P. When the number of rotations of the pinch roller P exceeds a fixed number of rotations, a fluid I filled in a tube portion E of the pinch roller P is given centrifugal force and pushed aside to the outer peripheral portion. Accordingly, the outer peripheral portion of the tube portion E is deformed to press the paper money A to a magnetic head H. Thus, stable reading operation for paper money A can be ensured.
