IPC: H02M5/27
Filed: 1978-09-19
Abstract: PURPOSE: To shorten dead time in case of change-over, by supplying arms, which must be conducted each time, with ignition pulses before regular gate pulses are given when converting the forward side and the inverse side in a converter for operating a cyclo-converter, etc. in a four quadrant shape.  
     CONSTITUTION: The gates of AND gates G1∼G6 are opened by the logic (1) of change-over signals P assigning a converter 1 at the forward side, ignition pulses u1∼z1 are let pass through the G1∼G6 and OR gates G7∼G12 and sequential ignition pulses equal to conventional devices are put out. The u1∼z1 are input to FF1 ∼FF6, thus memorizing the last gate pulse each time. Meanwhile, a single-stable multiplier MS1 is triggered by the inversion of the change-over signals P when changing over converters to the converter at the forward side from a converter at the inverse side, and the signals are input to the gates of AND gates G13∼G18 only by the time limit. Thus, arms, which must be ignited after change-over, are selected through the G13∼G18 that the gates are opened by means of the FF1∼FF6, and gate pulses are supplied to an arm of interest before regular ignition pulses are generated.

Abstract: PURPOSE: To enable shutter operation to be checked with a simple constitution by enabling the display part displaying shutter operation to be covered with part of shutter blades.  
     CONSTITUTION: Shutter blades 1, 2 are provided with spindle type shutter holes 1a, 1b and aperture holes 2a, 2b for photo detectors. One end of the blade 2 is provided with a protrusion 2d extending to the front of a finder field mask, and with the shutter being held closed, the display hole 9b of the field mask is held covered by the protrusion 2d of the blade. When the shutter is pushed, a motor starts running and the blades move mutually in the opposite direction. A photographing opening is then formed by the holes 1a, 1b in front of the photographic lens 3, and exposure is accomplished. Since the protrusion 2c of the blade moves with the openning of the shutter and retreats from the position covering the display window of the field mask, a color corresponding to a filter 10 appers in the center of the visual field, by which it is indicated that the shutter has actually actuated, thus the shutter operation may be checked
