IPC: G03B9/08
Filed: 1983-05-18
Abstract: PURPOSE:To simplify input/output relation between signals of a camera which controls an aperture value and an exposure time electrically by actuating a circuit which controls both with a signal shutter release signal. CONSTITUTION:When a switch 11 is closed through releasing operation, the output of an RS flip-flop goes up to a level H after a timer 19 measures a specific time and inputted to a terminal (a) of a control block 15. Then while an electromagnet 30 for trailing-curtain control and a light emitting element 33 are powered on, mechanical stopping-down operation starts and an impulsive output is generated at a terminal by a pulse generator (comb-tooth body for intermitting light) and inputted to a counter type coincidence circuit for the control over an electromagnet 26 for aperture determination. When a switch 12 is opened by shutter release, a timer 22 for shutter control starts operating to reset an FF20 a specific time later, and a TR32 is turned off, thus completing the exposing operation.

Title: Vacuum chuck device
Inventor: UCHIMURA TAKASHI
IPC: H01L21/30
Filed: 1986-04-16
Abstract: PURPOSE:To make it possible to prevent a rotary shaft from making into eccentric contact with the inner surface of a seal member to a large degree even though the rotary shaft deflects, by providing a housing fitted therein with the rotary shaft through the intermediary of the seal member, movably with respect to a drive motor. CONSTITUTION:When vacuum pressure is fed into the inside 5a of a housing 5, a base plate chuck 3 sucks up a base plate 13 as a workpiece through a suction hole 2a in a spin shaft 2. At this time, the housing 5 is urged against the spacer 7 side along the spin shaft 2 while it is self-aligned. Then, during rotation by a spin motor 1 when the spin shaft 2 laterally deflects a change in surface pressure between the spin shaft 2 and a seal bushing 6 is effected. However, since the housing 5 is attached with a gap being defined with respect to a fastening member 8 so that the housing 5 is movable in both radial and axial directions, the change in surface pressure may be reduced. Thus, even if the rotary shaft deflects, no strong eccentric contact is prevented between the rotary shaft and the inner surface of the seal member.
