Abstract: A liquid crystal display panel (1) is so constructed that a plurality of pixels (2) are arranged in a matrix form having the number of lines twice that of horizontal scanning lines for one field of interlaced scanning video signals (VID) obtained by scanning an original image every other line, the arrangement of the pixels (2) being shifted horizontally by one-half of a pixel (2) between adjacent upper and lower lines. A row driving circuit (7) applies, to the pixels (2) in the upper line of the two adjacent upper and lower lines, data voltages obtained by sampling a video signal (VID) representing one horizontal scanning line by a clock signal (SCK) of the timing that matches the number of pixels (2) in the upper line and the arrangement of the pixels (2), and applies, to the pixels (2) in the lower line, data voltages obtained by sampling the above video signal (VID) representing one horizontal scanning line by a clock signal of the timing shifted by 1/2 cycle from the above clock signal (SCK). Thus, one horizontal scanning line represented by the video signal is displayed using the two upper and lower lines of pixels (2), thereby enhancing the display quality of the produced image.

Abstract: A communication network, such as an audiovisual system, on an automobile has a master unit and a plurality of slave units which are connected to a common communication bus. When the communication network starts operating, connection confirmation request information is transmitted from the slave units to the master unit. The master unit awaits connection confirmation request information from at least one of the slave units for a predetermined period of time after the communication network starts operating. Thereafter, the predetermined period of time is extended if the reception of connection confirmation request information from all the slave units that were connected when the connection network stopped operating in a preceding cycle is not completed. If reception acknowledgement information from the master unit is not detected for a predetermined period of time, then the slave units automatically enter a low power consumption mode.

Abstract: The invention relates to a regulated DC power supply circuit (10) comprising a full wave rectification stage (12) for rectifying an AC input and a regulating stage (14) for regulating an output voltage from the rectification stage. The regulating stage (14) has a primary voltage regulating circuit (20) and a secondary voltage regulating circuit (22). The primary voltage regulating circuit includes a series pass element, such as a MOSFET device (T1), connected to operate continuously in source-follower mode. A primary voltage reference element, such as a zener diode (Z4), provides a gate reference for the series pass element (T1). The secondary voltage regulating circuit (22) is cascaded to the primary voltage regulating circuit in a voltage sharing configuration. The power supply circuit is therefore capable of handling input voltages over 1kV, which exceed the maximum voltage rating of thee MOSFET device. The invention extends to a DC voltage regulator, which includes the regulating stage (14) without the rectification stage (12).

Abstract: The invention relates to a contact- and battery-less chip card with an antenna coil, a transmitting and receiving stage which, via an electromagnetic alternating field generated by a reading/writing device, supplies the chip card with power, on the one hand, and, on the other hand, carries out the bidirectional data transmission to the reading/writing device. Such chip cards have the disadvantage that, in particular, functions of the chip card with a high power requirement can only be reliably executed within a very restricted range around the reading/writing device. Said functions include, for example, the programming of the read-only memory of the chip card. According to the invention, the chip card exhibits a detector for determining the field strength of the alternating electromagnetic field transmitting power to the chip card. The functions of the section of the application which have a high power requirement during execution are advantageously executed only when the detector has detected an adequate field strength. This prevents faulty or incomplete execution of power-consuming functions of the chip card even before they are begun. <IMAGE>

Abstract: A variable camshaft timing arrangement for an internal combustion engine in which a camshaft, for example, an intake valve operating camshaft (34) in a dual camshaft engine, is advanced or retarded in its position relative to the crankshaft (22) and to the exhaust valve operating camshaft (26) in reaction to torque pulsations in such intake valve operating camshaft (34). The camshaft has a sprocket (32) oscillatingly mounted thereon, or on the other camshaft of a dual camshaft system. The camshaft carrying the oscillatingly mounted sprocket (32) also has a bracket or another sprocket (30) keyed thereto, and the bracket or other sprocket (30) is chain driven by the rotation of the crankshaft (22) . A pair of single acting hydraulic cylinders (54,56) interconnect the oscillating sprocket (32) and the bracket or other sprocket (30), with the piston ends of the cylinders (54,56) pivotably attached to the oscillating sprocket (32) and with the body ends of the cylinders (54,56) pivotably attached to the other sprocket (30) or bracket. The cylinders act in opposite directions and are hydraulically interconnected so that one extends as the other retracts and vice versa. The hydraulic system includes a control valve which is controlled by an engine controller to selectively permit one of the cylinders to extend, and the other to retract, in reaction to torque pulsations in the camshaft (34) which is being advanced or retarded to provide desired engine operating characteristics. The camshaft which is being advanced or retarded can either be the camshaft which carries the oscillatingly mounted sprocket, or, in a dual camshaft system, it can be the other camshaft or both camshafts. In an engine having cam followers of the friction type, the unidirectionally acting torque on the camshaft which results from the friction between the camshaft and the followers can be offset by providing resilient means to act on one of the opposed cylinders to introduce a countertorque into the camshaft which is oppositely directed to the frictional torque.

Abstract: A raster scanner system (Fig. 1) is disclosed which utilizes a pair of binary diffraction optic lenses (60;62) to correct non-uniformity of the flux of a light beam (16; Fig. 1) received by a facet (18;Fig. 1) of a rotating polygon. Since the facet is rotating and the direction of the light is constant, the amount of the light (flux) which the facet receives in each position from the start of scan to the end of scan and in any position therebetween is different. Also, the light beam striking the rotating facet has a Gaussian distribution (30) which is a contributor to the non-uniformity of the flux over one scan line. The binary diffraction optic lenses (60;62) of this invention reprofiles the Gaussian distribution (30) into a profile (64) in which the intensity of the light beam gradually increases as the facet rotates to provide a uniform flux for the entire scan line.
