Title: Shutter control circuit of electric shutter camera
Inventor: KITAGAWA MASAHIRO
IPC: G03B7/08
Filed: 1980-05-27
Abstract: PURPOSE:To prevent under-exposure photographing by turning off a power voltage detecting circuit while an exposure control circuit is in photometric operation. CONSTITUTION:While a power detecting circuit 12 shows that a power battery is still undeteriorated, the hold transistor (TR) Q4 of a power holding circuit 11 is in an on-state and a shutter is kept open via a manet Mg, so that the photometric operation of an exposure control circuit 14 is started. Simultaneously, a low-level signal is applied to an NAND circuit ND1 via a resetting TR Q13 and consequently while the output of an RS type FFRS1 goes to a low level, the output of an RS type FFRS2 stays at the low level during the photometric operation. Therefore, the hold TR Q3 of the circuit 11 turns on via an inverter IN4 to detect a voltage drop by the circuit 12, and even when the TR Q4 is turned off, power is applied from the circuit 11 to the circuit 14, so that the circuit 12 is turned off substantially during the photometric operation. Thus, the open shutter is never closed during the photometric operation owing to a drop in power voltage, preventing under-exposure photographying.

IPC: F02D41/14
Filed: 1993-03-30
Abstract: PURPOSE:To properly coordinate air fuel ratio feed-back control with evaporated fuel introduction by increasing a purge amount of the evaporated fuel when a signal of an O2 sensor is reversed from a rich condition to lean one. CONSTITUTION:An O2 sensor 20 for generating the output based on the oxygen concentration in exhaust gas is provided in an exhaust path 19.

At this time, deflection of a leaf spring 14 is increased, and its pressing force to the member 8 is also increased, and hence the member 8 is brought into contact with a spherical seat of an actuator 9c. When two screws 17 are screwed in by an equal amt. to each other, the member 8 is passed through a principal point of the objective lens, and is turned around an axis parallel to a track direction. By such a screw fitting operation of the screws 17, the inclination of the optical axis of the objective lens 1 can finely be adjusted.
