    摘要: The present invention relates to an exposure computation circuit by means of which a computation is carried out with the values inversely proportional to all the exposure factors excepting the diaphragm value of the APEX system so as to obtain computation results in proportional relation with the actual shutter time value or the actual diaphragm value in order to control the exposure basing upon the computation results.

    摘要: Apparatus is disclosed herein which detects breaks in spinning yarns in ring spinning frames or the like and in particular senses vibrations inherent to a yarn guide disposed on a bobbin when the yarn guide comes into contact with the spinning yarns. The apparatus achieves quick inspection of whether breaks occur with the spinning yarns by the presence and absence of the vibrations, thereby monitoring joints in the spinning yarns and the operating state of the spinning machine.

    摘要: A multi-gray level display designed to display multi-gray level images free of flicker or the like, by using a small number of voltages. The display comprises a first gray-level pattern generating circuit 311 for generating a first gray-level pattern which acquires a gray level during m frame periods, a second gray-level pattern generating circuit 321 for generating a second gray-level pattern which acquires another gray level during n frame periods (n is a positive integer greater than m), and a selection circuit 341 for selecting and outputting one of the preset voltages, in accordance with an output from the first gray-level pattern generating circuit 311 or the second gray-level pattern generating circuit 321 when the input multi-gray level display data corresponds to a gray level of either the first gray-level pattern or the second gray-level pattern.

    摘要: A clearer mechanism for a draft roller, a clearer holder supporting a clearer member therein, and a suspensory member suspended from the draft roller and detachably supporting the clearer holder such that the clearer member is held against a working periphery of the draft roller. The mechanism further includes an actuating member or a restraining member projecting from either of the clearer holder and the suspensory member for displacing the actuating member or the restraining member to thereby reciprocally move the clearer holder along the working periphery of the draft roller.

    摘要: A retainer frame supportiing pat type clearer members is arranged in opposed relation to a draft roller. The retainer frame is inserted at both longitudinal end portions thereof into insert grooves of supporting brackets mounted on roller stands or draft roller bearing members placed on the roller stands. The retainer frame is formed by folding a metal plate. Each of the clearer members is formed with stopper lugs at both side edges thereof. With this arrangement, each clearer member may be easily installed into the retainer frame, and a uniform projection of the clearer member from the retainer frame may be maintained.

    摘要: A diaphragm aperture value which has been set is transformed into corresponding frequency information. A local oscillator starts sweeping upon pushing of the shutter button. The output of the local oscillator and the frequency information are inputted to a mixer, and the output of the mixer is fed to a filter circuit, whose center frequency is variable according to the luminance information of an object to be photographed. Only a specific output frequency of the mixer passes through the filter circuit, and the output of the filter circuit generates a control signal which closes the shutter at a suitable diaphragm aperture time.
