Title: Exposure controlling circuit
Inventor: UCHITOI MASANORI
IPC: G03B7/093
Filed: 1979-05-08
Abstract: PURPOSE: To realize accurate exposure control, by setting the duration of time measuring for exposure shorter than the exposure time of the shutter.  
     CONSTITUTION: When the shutter front curtain starts to run by shutter release operation, the time is measured by resistance Rv and capacitor C 1 , and after regulated time comparator COM outputs 1. As a result of output from comparator COM, pulses from a pulse oscillator are fed to a main counter MC, so that the measurement of exposure time is started. Since 1 is set in FF 3 , counter CON takes the output from FF 4  as 1, and causes NAND gate N 10  to output a shutter closing signal. Since the output of F 4  is a pulse of 8kHz, when four pulses are counted, the time becomes 0.5ms. After lapse of this time, a magnet MG for rear curtain holding is driven by a magnet driver MD, and the shutter rear curtain is caused to run after the response delay time of the magnet, thus finishing the exposure.

Abstract: PURPOSE: To reduce the formation of a gap in the proximity of a lip due to the clearance at a diaphragm and to enable the diaphragm to be prevented from sliding by a simple structure, by a method wherein the number of lips in a center disc and a ring is caused to amount of 3 or more in all.  
     CONSTITUTION: In the prior art, the usual number of lips on a center disc 25 and a ring 27 is 2. But, this causes the formation of a gap near the lip 40 due to clearance at a diaphragm 4, and as a result, the diaphragm 4 often slides resulting from the use for a long period of time. In the drawing, the lips 40, the number of which is 3, are illustrated. In this case, the gap 42, produced due to the clearance at the diaphragm 4, is provided outside the 2 lips 40, which are positioned at opposite ends, out of the 3 lips 40, and is not formed at the centrally-located lip 40 where a gap has been produced in the prior art. As a result, the diaphragm 4 is not provided with a relief space, and thus, a simple structure allows the diaphragm to be effectively prevented from sliding.

Abstract: PROBLEM TO BE SOLVED: To obtain wavelength loss characteristics which are nearly completely flat in a passing area by using multimode interface(MMI) waveguides and connecting two array waveguides in point-symmetrical arrangement on one substrate opposite each other. SOLUTION: A 2nd array waveguide 30 has the same structure with a 1st array waveguide 20 on the other side on a substrate 10 and is arranged opposite the waveguide 20 in a point symmetrical state and also connected to the waveguide 20 through an MMI waveguide 7 which is increased in core width so that higher-order modes can be propagated as well as a basic mode.
