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 automatic steering device is presented for controlling the direction of travel of an asphalt finisher during a paving operation. The device is provided with a laser generator (18) which projects a laser beam of a slit shape on a series of objects along the roadside which is selected to served as a reference line (A). An image recording device (17), a CCD camera, is disposed on the vehicle member (2), which records the projected laser light illuminating the objects and outputs a generated image (Ba) to a master controller (22). The master controller (22) determines the current deviation of the vehicle member (2) from the reference line (A) by the changes in the position of the generated image (Ba), and operates the automatic control device so as to steer the vehicle member (2) in the correct direction to permit the asphalt finisher to follow the reference line (A).

摘要： Efficient paving operation requires that the levelling operation of asphalt be carried out accurately along a reference line which follows a given direction along a roadside. A simple and effective automatic control device for controlling the steering direction in conjunction with adjustments of the screed for an asphalt finisher (shortened to finisher) is presented. The control device automatically regulates the extension or retraction of the screeds on both sides of the finisher in reference to a visual display of the reference line following some objects along the roadside. The visual detection system of control is simple and economical and provides an accurate control over the direction of paving.

摘要： It is an object of the present invention to provide a recording apparatus and a reproducing apparatus which change a picture compression rate depending upon a picture quality of a source which a user desires to retain, thereby a tape storage space being secured. A video-data compression rate N used by a 1:N video-data compression encoder 3 and a 1:N video-data compression decoder 6 is changed depending upon a picture quality set by a device 5 for setting a picture quality that a user desires. A tape travel speed of an archive VTR 4 is changed in response to the picture compression rate. Thus, an amount of a tape travel is optionally set depending upon a level of the picture quality. Therefore, it is possible to optionally select a tape storage space in response to the level of the picture quality.

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 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.
