Abstract: A photoelectric sensor comprises a thin plate-shaped optical body (1), a circuit block (4) and a tubular casing (2) for incorporating therein the optical body and the circuit block. A signal light incoming through a transparent protector of the casing is reflected upon a first reflective mirror (1c) of the optical body. Following this first reflection, a second reflection is made upon a second reflective mirror (41a) thereof. The light having passed through a light collecting lens is received by a photoelectric converting element (4a) and converted into electric signals for output. Since the optical body comprises a plurality of reflective surfaces, an optical path up to the photoelectric converting element can be incorporated compactly within the thin plate-shaped optical body.

Abstract: A circuit technique is presented for mixing current mode logic and emitter coupled logic in a manner which reduces active and passive component counts for performing recognized logic functions. The reduced counts permit greater circuit density while reducing power consumption in comparison to conventional emitter coupled logic circuitry. The mixing is also provided in a way for making all inputs and outputs compatible with conventional emitter coupled lologic levels. Various logic circuits are illustrated to demonstrate the versatility of the technique. For example, a transparent high D-latch (Fig. 2), a D flip-flop with true output (Fig. 4), a two-to-one multiplex latch (Fig. 6), and other D flip-flops having set and reset inputs (Fig. 7), multiplex data inputs (Fig. 8), and Exclusive OR data inputs (Fig. 9) are circuits wherein the inventive technique is employed to advantage.

Abstract: A high definition television augmentation channel which provides an efficient use of bandwidth, time expands line differential, panel, and luminance signals. The time expanded line differential signals are arranged in time coincidence and quadrature modulated, as are the corresponding segments of the panel signals. The quadrature modulations providing signals in a common frequency band. Luminance signals are converted to the common frequency band and time multiplexing of the three signals is performed. The resulting time multiplexed signal is then frequency multiplexed with the DSS signals which have been frequency converted to occupy a frequency band contiguous with the common frequency band. A decoder operates in the reverse direction.

Abstract: A high contact force, high elastic response range pin-receiving electrical contact (10) includes a base portion (18) and a pair of spaced apart cantilever beams (26, 28) which extend forwardly from the base to a pin-­receiving end (12). A pair of inwardly directed contact surfaces (34, 36) is defined one on each cantilever beam facing the opposed beam for slidably, electrically engaging an inserted pin terminal. A resilient beam support member (54) extends from and interconnects the pin-receiving ends (30, 32) of the cantilevered beams (26, 28). The resilient beam support member (54) increases the elastic response range of the pin-receiving contact by enabling each cantilevered beam (26, 28) to endure a greater outward displacement before a minimum yield in the beam occurs while providing a greater normal force against the pin.

Abstract: A biopolar analog voltage is converted into a digital signal by sensing the polarity of the voltage and selectively supplying a bias voltage to an analog-to-digital converter, which can preferably be a charge balanced voltage to frequency converter (13), as a function of the sensed polarity. The voltage to frequency converter (13) has a double valued variable frequency output with a discontinuity at zero volt such that the converter derives a maximum output frequency for a maximum positive voltage and also for a negative value slightly displaced from zero; the voltage to the frequency converter minimum output frequency is derived from positive voltages slightly greater than zero and for maximum negative voltages. The converter output frequency and the sensed polarity are supplied to a frequency to digital converter (16) which derives an output signal having a bit representing the polarity of the analog voltage and additional bits indicative of the magnitude of the analog voltage.

First and second coders (4-1, 4-2) respectively code the first and second groups of image data into first and second groups of coded image data. The first and second groups of image data in the original image data are respectively input into first and second memories (3-1, 3-2), respectively. Blocks of the first group of image data are supplied to the first coder (4-1) at first times, respectively, and blocks of the second group of image data are supplied to the second coder (4-2) at second times, respectively. Boundaries of the blocks in the first group of image data are located in different positions from boundaries of the blocks in the second group of image data, and the first times are different from the second times. In the receiver side, first and second decoders respectively decode the above first and second groups of coded image data into first and second groups of decoded image data. By composing the first and second groups of decoded image data, the original image data in the bit map form is restored.

Abstract: The invention relates to a procedure to determine the geometry of the cross-section of a longitudinal workpiece coming out of a profiling machine with the aid of an electronic array camera. In order to increase the resolution of this camera, whose pixels (6) are arranged in a regular array, a plurality of images of the cross-section are recorded successively, it being the case that during these recordings the cross-section is displaced in X- and Y-directions of the image plane at a rate such that the path covered between two successive recordings amounts in the X- and Y-directions to a fraction of the separations of the adjacent pixels (6), taking account of the image scale. Taking account of the direction (P) of the displacement of the cross-section in the image plane, a computer is used to determine from the number of the recordings of each cross-sectional point, which requires these recordings for the purpose of passing to the neighbouring pixel from a pixel or a point located between two adjacent pixels, the position of this cross-sectional point. <IMAGE>
