IPC: G03B9/36
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a focal-plane shutter provided with a mechanism for adjusting a driving spring capable of being manufactured at a low cost. SOLUTION: A driving member and a spur gear 16 are rotatably attached to a shaft 1d provided between a shutter base plate and a supporting plate 9, and the driving spring 18 is hung between the driving member and the gear 16. The driving force of the spring 18 can be adjusted by rotating the gear 16 by means of a worm 20. Holes 9d1 and 9e1 are formed on the two bent parts 9d and 9e of the plate 9, and the branch part of the hole 9d1 opens, so that the hole can be made large. The leading end part of the worm 20 is inserted from the hole 9d1 so as to be fitted in the hole 9e1 . At that time, since a tapered part 20c opens the branch part, elastic force is given to the branch part, and the worm 20 can not be rotated by force other than human power in an attached condition.

Title: Phase difference measuring circuit system
IPC: H03K5/26
Filed: 1992-02-27
Abstract: PURPOSE:To measure the phase difference without using a special element by logically discriminating whether the phase difference between two pulses is within a prescribed range or not. CONSTITUTION:Pulse signals (a) and (b) are inputted to clock inputs CK of flip flops (FF) 11 and 12 respectively, and the FF 11 is reset before the FF 12, and respective outputs Q are changed with the same time difference. When both outputs Q go to the high level together, an AND gate 13 outputs the signals in the high level to both reset inputs R to reset FFs 11 and 12. Therefore, a pulse signal having the same time width as the phase difference between two pulse signals appears as a signal (c), and a whisker pulse signal due to signal delay between elements appears as a signal (d). Signals (c) and (d) and signals obtained by delaying them by a prescribed time are inputted to logic circuits 4 and 5, and signals (e) to (j) are outputted after logical operation. Thus, it is logically discriminated whether the phase difference between two pulses is within the prescribed range or not.
