Abstract: PURPOSE:To inform a photographer of a photographable period by providing a reference level varying means which varies the relative value of a reference level to the charging level of a main capacitor according to variation of irradiation characteristics and displaying the completion of charging to a level suitable for the irradiation characteristics. CONSTITUTION:When a power switch 2 is closed, a DC-DC converter 3 operates to charge the main capacitor 6. Then, a voltage V1 divided by resistances 7 and 8 is inputted to the uninverted input terminal of a comparator 18. A constant voltage VREF, on the other hand, is developed by a reference voltage generating circuit 12. Then, one of contacts (a), (b), and (c) of a switch 17 is selected associatively with a change in zoom state by the photographer to set a turn-on voltage Vi, which is inputted to the inverted input terminal of the comparator 18. When the voltage V1 rises above a level higher than the turn-on voltage Vi, a switching transistor 22 turns on and a pilot lamp 23 illuminates to inform the photographer of a photographable period.

Filed: 1994-09-30
Abstract: PURPOSE: To simplify a structure and to suppress elastic deformation in a bush so as to reduce play by fitting an elastic bush inside a mounting hole formed in one member and inserting the other member into the bush. CONSTITUTION: In a Z-shapedly bent link 10, tip parts 11 on both sides are inserted freely rotationally into a mounting hole 4 at the tip of stabilizer arm 13 and into a mounting hole 13 in a bracket 9 via bushes 12 consisting of elastic bodies made of synthetic rubber or the like.

Abstract: PROBLEM TO BE SOLVED: To provide a light emitting element drive circuit improving the deterioration in a bit error rate in the communication system by controlling a mark rate of a binary signal driving the light emitting element to be a known mark rate so as to prevent waveform deterioration in the optical signal of the light emitting element caused by a fluctuation in a bias component of the binary input signal and a threshold level. SOLUTION: A binary input signal (A) whose waveform is unsharpened is compared with a threshold level (D) by a comparator circuit 2 and becomes a shaped binary signal and it is used to drive a light emitting element 6 via a load drive circuit 1. A mark rate detection circuit 3 detects a mark rate (C) of a shaped binary signal (B) to give it to a threshold level control circuit 4. The threshold level control circuit 4 controls the threshold level (D) so that the shaped binary signal (B) has a known mark rate of the binary input signal (A). Thus, waveform deterioration in the optical output of the light emitting element 6 caused by the fluctuation in the bias component of the binary input signal (A) and the threshold level (D) is prevented and the deterioration in the bit error rate of the communication system is improved in the light emitting element drive circuit.
