Abstract: A resist 4 is printed on the areas where the dynamic pressure generating grooves 2 are to be formed, on curved surface of a shaft core member 1a. After the resist 4 is hardened by baking, hard electroless plating is conducted to form a plated layer 3 of a thickness equal to the depth of the grooves 2. Then the resist 4 is removed to obtain a shaft 1 with dynamic pressure generating grooves 2. The dynamic pressure during rotation is free from fluctuation as the dynamic pressure generating grooves are highly precise and constant in the depth and in the cross-sectional shape.

Abstract: A motor-driven camera comprising a film winding and rewinding mechanism operable by a starter switch, and a low power consumption type memory unit. The film winding and rewinding mechanism include a transmission changeover gear. For sliding this gear a motor is rotated backward once to eliminate a contact between teeth of the changeover gear and a drive gear operatively connected to the motor. The memory unit includes a flip-flop memory circuit and a switching circuit. The memory circuit shifts from a first state to a second state and remains in the second state when the starter switch is closed. In the second state the memory circuit outputs an operation signal to a transmission mechanism control unit, and returns to the first state upon receipt of a signal output by the control unit when an operation is completed. The switching circuit performs a positive feedback function with respect to the closure of the starter switch.

Abstract: A command device for a dobby machine, which device includes a pattern card having a plurality of perforations bored in a pattern corresponding to a desired fabric and driven in one direction and a feeler needle suspended from a horizontal needle and displaceable longitudinally while being guided by a guide member so as to permit the insertion of a lower end portion thereof into the perforations and the detection of presence or absence of the perforations in the pattern card, whereby to give an operational command to a drive mechanism of the dobby via the horizontal needle so as to cause a heald frame to undergo prescribed up-and-down movement for production of the desired fabric. The feeler needle is elastically flexible in the direction of motion of the pattern card at a portion below the guide member so as to avoid damages to edge portions of the perforations of the pattern card, which damages would otherwise take place due to repeated reciprocation of the feeler needle into and out of the perforations.

Abstract: The drive force of a motor built in a camera is separately transmitted through respective clutches to a film drive device for one-frame film wind-up and a shutter mechanism for shutter cocking. The film drive mechanism is associated with a detector for detecting completion of the film wind-up operation, while the shutter mechanism is also associated with another detector for detecting completion of the shutter cocking. The detectors generate a "high" or a "low" digital signal corresponding to the detections. A discriminating circuit logically determines whether the wind-up operation is completed, according to the timed relationship between the signals, and detects the end of the film being reached when the film wind-up has not been terminated upon detection of the shutter cocking completion. By this detection, motor drive for film wind-up is stopped, subsequent shutter release is forbidden and motor drive for film rewinding is initiated.
