摘要： PURPOSE:To surely synchronize the opening/closing operation of a shutter with the rotation of an intersprocket without using any mechanism member by generating a pulse signal by a 2nd control pulse generating means in synchronism with the rotation of a 1st motor and driving a 2nd motor according to the pulse signal. CONSTITUTION:A pulse generating circuit 49 oscillates the pulse signal of 400 pulses every time a servomotor 13 makes two rotations. When the pulse signal is inputted from the pulse generating circuit 49, a servo-amplifier 39 compares the number of pulses of the pulse signal with the value obtained by doubling the number of pulses sent from a pulse generator PG2 and drives the servomotor 27 so that the both become equal to each other. Consequently, the pulse generating circuit 49 generates the pulse signal in synchronism with the rotation of the servomotor 13, so the rotation of the intersprocket 17 can surely be synchronized with the opening/closing operation of the shutter 9.

摘要： PURPOSE:To detect abnormality of a film even when the film is partially broken by detecting the abnormality of the film according to time-series data of detection signals sent from film perforation detecting means. CONSTITUTION:The couple of film perforation detecting means 31 and 33 arranged at specific positions on a film conveyance path detect perforations at both edges of the film F which passes the positions. The perforations are provided at both the edges of the film F at equal intervals, so the detection signals which are sent from the film perforation detecting means 31 and 33 are sent normally corresponding to the passing speed of the film F at the specific positions and the time-series data of the respective detection signals, therefore, become regular matching a specific pattern. If, however, the abnormality such as the breaking of the film F occurs, the time-series data become irregular. A judging means inputs the detection signals as the time-series data and judges that the film F is abnormal according to three-series data. Consequently, even if the film is partially broken, the abnormality of the film can be detected.

摘要： PURPOSE:To surely perform framing by a specific quantity through single operation by increasing or decreasing the angle of rotation of an intersprocket, which rotates when an optical path is closed, by a specific quantity by a rotational angle varying means and adjusting the frame position of a film about the optical path. CONSTITUTION:The film F is irradiated with light corresponding to the frame size from a light source 5 and the intersprocket 17 rotates intermittently in synchronism with the closure of the optical path, extending from the light source 5 to the film F, by a shutter 9, thereby conveying the film F, frame by frame. When an operation part is operated here, the rotational angle varying means increases or decreases the angle of rotation of the intersprocket at the time of next optical path closure by the specific quantity to adjust the frame position of the film F about the optical path. Consequently, the framing is easily performed.

摘要： PURPOSE:To test with large quantity and surely a circulatory function supporting device and make it possible to correspond to an increasing demand by providing a duty ratio setting part setting a time allotment on feed and discharge of a specified fluid on each circulatory function supporting device fixed on a fluid controlling part. CONSTITUTION:An input and output port 44d is connected with a display part 44f for the aimed value setting and actuating state of various pumps and regulators set on the front panel, a period setting part 44g, a period display part 44h and 12 three-way solenoid valve controlling parts ch1-ch12, which are each constituted of a duty ratio setting part, a duty ratio display part, a count display part, a duration time display part and a test period setting part as a set. Utilizing stable driving pressures and discharge pressures of the three-way solenoid valves 28a-28l as a pressure source, switching controls of the valves of the three-way solenoid valves are performed. The control system of the driving period is made thereby a unified and single constitution and it is made possible to drive various duty ratios under the control of the period.
