    摘要： A measuring arm (12) is attached to a frame (5a) supporting a screed (5). Height sensors (13) and (14) are attached to the measuring arm (12), and a height sensor (19) is also attached to the arm (18) of the screed (5). The spacing must remain constant between the rear end of the screed (5) and the height sensor (19), between the height sensor (19) and the height sensor (14), and between the height sensor (14) and the height sensor (13). A distance sensor to calculate the travel distance is provided on the tractor unit (1). The relative height Ho of both height sensors (13) and (14) to the screed (5) must always remain constant, regardless of the tilt of the screed (5) and the measuring arm (12). The sensors (13), and (14), and (17) are connected to the arithmetic unit (30). The height sensor (19) is connected to the arithmetic unit (40). The arithmetic unit (30) receives an output signal from the height sensors (13) and (14) and calculates the thickness of the pavement. The arithmetic unit (40) detects the uneven level of the unpaved surface on the basis of the output signal from the height sensor (19) and controls the screed (5) in order to offset the unevenness.The operating conditions are set on the control unit (30) via a recording medium such as an IC card.

    摘要： An optical transmitter converts serial hi-vision digital signals sent from a transmitting side peripheral device over a coaxial cable into serial digital optical signals to transmit the resulting signals over an optical fiber. An optical receiver receives the serial digital optical signals sent from the optical transmitter over the optical fiber to convert the signals into serial hi-vision digital signals to transmit the converted signals over a receiving side coaxial cable to a receiving side peripheral device. This enables transmission of digital signals to the receiving side peripheral device with suppressed signal deterioration without requiring a complex structure.

    摘要： In an apparatus for use with a video tape having a longitudinal track in which an address signal is recorded and successive slant tracks in which a video signal and an information signal are recorded at predetermined intervals; a magnetic head unit reproduces the video signal, the information signal, and the address signal. The information signal is applied to a pulse generator for generating a control pulse signal, and an address indication circuit provides an address indication in response to the address signal or the control pulse signal. A control circuit is provided for coupling one or the other of the address signal and the control pulse signal to the address indication circuit selectively in response to the speed of movement of the tape.

    摘要： A servo circuit is provided for use with a reproducing apparatus wherein an information signal is reproduced from an elongated slant track formed on a tape which is wrapped on the periphery of a guide drum having a rotary head. The servo circuit includes a circuit for detecting an intermediate point of the length of the slant track and generating a timing signal at the detection of the intermediate point and a circuit for comparing the timing signal with a reference pulse to generate a control signal. A relative position of the slant track to the rotary head is controlled in accordance with the control signal.

    摘要： In a machine tool controller (1): a position control unit (12) controls, based on an operational signal input from without during manual operation, a moving body's move-to point and moving speed; a memory (13) stores data modeling the moving body and any potentially interfering machine-tool structure; a travel-area checking unit (17) defines in the modeled structure speed-control regions obtained by displacing the structure's contour, generates, based on the defined speed control regions and on current moving-body position, data modeling the moving body as moved into its current position, to check whether the moving body will travel within a speed control region, and if so, sends to the position control unit a speed limit predefined for that speed control region. The position control unit controls the moving body to travel at speed limit if the operational-signal-directed moving speed exceeds the speed limit.
