摘要： In an optically scanning displacement detector for determination of an object's profile, the detector comprises a light projecting unit for radiating a light beam on the object, a light receiving unit for receiving a reflected light beam from the object to output an object position signal, and a distance determining unit for determining a distance between the projecting unit and the object in accordance with the object position signal. The light projecting and receiving units are mounted in a carrier which is movably supported to a frame. The carrier can be moved in a scanning direction to scan the light beam across the object by the use of an electric motor such as a voice-coil linear motor. Since the present detector does not use a scanning mirror for deviating the light beam, the object's profile can be determined with improved accuracy of measurement, while preventing a formation of dead space in which the light beam can not be radiated during the scanning operation. The detector also comprises a carrier position sensor for determining a position of the carrier in the scanning direction, and a safeguard unit for sensing unusual operation of the motor to generate a stop signal, and stopping a supply of electric current to the motor in response to the stop signal.

摘要： An optical sensor discriminating the presence of an object or detecting distance to an object which includes a light projecting element for projecting light to a detection area, a light receiving element for receiving light reflected from an object present in the detection area and an anamorphic light receiving lens for expanding a condensed light spot received on the light receiving element in a direction perpendicular to a direction of movement of the light spot on the light receiving element. The light receiving element outputs a detection signal which discriminates the presence of the object in the detection area. The light receiving element can be rectangular in shape and comprise two or more triangular shaped photodiodes which output detection signals that can be processed to determine a distance between the object and the light receiving element. A movable prism can also be provided to compensate for movement of the object other than towards or away from the light receiving element to avoid erroneous distance measurement which might otherwise occur.

摘要： A connector receptacle (20) is constituted by a contact (2) to which a data signal is serially communicated through a connector plug and a physical layer basic circuit (5) provided inside the connector receptacle (20) and adapted to perform specified processings so that the data signal is parallel communicated between the basic circuit and a link layer circuit for the communication. As a result, the distance between the contact (2) and the physical layer basic circuit (5) is short. Therefore, it is not necessary to pay so much attention as in conventional cases in designing a pattern layout (7) so as to prevent influence on the EMI and transmission characteristics, and it is easy to design the layout of the pattern constituting the transmission line for the data.

The internal power voltage is distributed to the internal circuits through a looped main power line, with an electrode pad for connecting an external capacitor for stabilizing the internal power voltage being provided on it, so that the internal power voltage is stabilized and the power consumption of the integrated circuit is minimized.
