Title: Synchronous traveling speed control circuit
Inventor: HIDA MASAKAZU
IPC: G05D13/62
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To provide a synchronous traveling speed control circuit by which a belt conveyor can be smoothly followed up with a simple pneumatic circuit. SOLUTION: By turning a cam plate 92 formed in a cam 9, the movement of a work W is detected, and in case of a forward movement, a rotational direction changeover valve 4 is changed over by a forward-movement control air valve 6 to turn an air motor 3 for moving forward a synchronous traveling device. When the forwarding speed is high, the cam plate 92 of the cam 9 is further turned to increase the displacement from an air motor 3 by a forward speed control air valve 8, so that the rotating speed of the air motor 3 is increased so as to catch up with the work W. In case of a backward movement, the rotational direction changeover valve 4 is changed over by a backward- movement control air valve 7, so that the air motor 3 is turned to move the synchronous traveling device backward.

Filed: 1986-09-17
Abstract: PURPOSE:To constitute the device simply and inexpensively by synthesizing a burst signal extracted by a 1st switch means, a burst signal extracted from a phase-locked oscillator and a signal extracted from the 1st adder at a 2nd adder. CONSTITUTION:A burst gate signal inputted from an input terminal 2 is fed to a flip-flop 5 to form a switch control signal inverted at each 1H. On the other hand, a PAL system chrominance carrier signal is inputted from an input terminal 1 and fed to the 1st switch 3. Then the signal is separated into a burst signal and a chrominance signal by the burst gate signal inputted from the input terminal 2. A chrominance signal from an adder 9 fed to an adder 11 and the burst signal from a phase shifter 10 are added and the result is outputted from an output terminal 12. Since the chrominance signal is identical at each 1H in the NTSC signal formed in this way, the quantity of information is half to the normal NTSC signal.

Title: Optical information recording/reproducing device
Inventor: OSAWA HIDEAKI
IPC: G11B7/085
Filed: 1987-09-07
Abstract: PURPOSE:To reduce the size and the weight of a device by sticking film shape first and second piezo-electric elements on the supporting part of an objective lens, and detecting the moved displacement of the objective lens. CONSTITUTION:The film shape first and the second piezo-electric elements 8, 9 are stuck on the supporting part of the objective lens. When the objective lens 1 moves in a tracking direction, a supporting plate spring 7 in the tracking direction is deformed into a curved shape, and the film-shaped first and the second piezo-electric elements 8, 9 having been stuck are similarly deformed. A potential difference is generated between the electrodes 14, 15 and the electrode 16 by this deformation, and the tracking direction of the objective lens 1 can be known by detecting this potential difference by a differential amplifier 17. Thus, the position of a tracking movable part can be detected through simple constitution and besides without inducing the increase of the weight and the size of the tracking movable part and a pickup head.
