Patent EP-0356365-A2 (EP)
Inventor: BARISH ARNOLD EUGENE
IPC: G06F11/22
Filed: 1989-07-12
Abstract: A circuit for testing a differential current switching logic circuit of the type including: a bias potential, two resistors connected to said bias potential, and means responsive to an input signal for sinking a first current through a selected one of the resistors so as to generate first and second differential output signals at the resistors. The circuit includes first, second, and third transistors, each having first and second terminals for conducting a current responsive to a signal applied to a control terminal. Means are provided for supplying a current. The first transistor has its first terminal connected to the current supplying means, and its second terminal connected to a circuit node. The second transistor has its first terminal connected to the circuit node, its second terminal connected to the bias potential, and its control terminal connected to sense the potential at a selected one of the resistors. The third transistor has its first terminal connected to the circuit node, its second terminal connected to the selected resistor, and its control terminal connected to sense the potential at the other of the resistors. The circuit functions to sense the potential difference between the first and second differential output signals. When the potential difference is less than a predetermined level, a second current is sunk through the one resistor so as to lower the potential of the output signal associated with the one resistor relative to the potential of the output signal associated with the other resistor.

Abstract: The functional layers, the edge metal contact layer and the conduction layer of the chip conductor bridge consist of a copper or nickel layer on which a soft solder layer is deposited. The functional layers are homogeneous and are deposited simultaneously. Centrally situated on the surface of the chip conductor bridge is a metal-free resist island which is routed around the conductor layer. In individual technological substeps, an island is printed on the substrate surface composed of resist layers, then the upper and lower faces of the substrate are covered with a structured auxiliary resist, broken into strips, and the strips are reductively electrolessly nickel plated, nucleated and dip-soldered.

Abstract: A digital information signal reproducing apparatus is provided, in which a relative speed between a record medium (1) in which a digital information signal is recorded and a reproducing device (2, 3) for reproducing the digital information signal from the record medium (1) is selectively changed. Even when the multiple of an over-sampling digital filter (4, 5) is switched in response to the switching of the relative speed, the frequency characteristic of an analog low-pass filter (9, 10) need not be changed, and thus the circuit arrangement of this digital information signal reproducing apparatus can be simplified.

Abstract: A passbook page turning mechanism includes a page turning station (12) provided with upper and lower rotatable rollers (38,40), independently movable parallel to a feed path (21) for the passbook (18). For feeding the passbook (18), the upper and lower rollers (38,50) grip the passbook (18) and move in synchronism parallel to the feed path (21). The upper and lower longitudinally movable rollers (38,40) serve as apparatus to turn the pages of the passbook (18). At the page turning station (12), the lower roller (40) is displaced along the feed path (21) from the upper roller (38) and is raised to flex the passbook (18). The upper roller (38) is rotated to initiate page turning and then moved parallel to the feed path (21) to complete the page turning operation, after which the passbook is moved to the printing station (10). The mechanism also provides for turning one or more pages in the opposite direction from the direction of a normal page turning operation.

Abstract: Printing on photo-sensitive materials is effected by a linear array (10) of light emitting diodes (LEDs) energised by a power supply unit 20. The LEDs (10₁ ... 10 x ) are simultaneously enabled by a strobe pulse (S). Each LED has an individual input to control whether or not it is energised during a strobe pulse (S). The different exposures for each pixel are achieved by selectively controlling the LEDs (10₁ ... 10 x ) in each of a series of weighted strobe pulses whose base durations are in a power of 2 series. For this end the exposure for each pixel along the line is stored as an n-bit word and successive bits are taken from the words by a bit slicer (38) to be entered in an array control memory (40). Due to transients mostly associated with the power supply (20), the energisation of the LEDs does not exactly follow the rectangular strobe pulses. A dual compensation technique is disclosed. A pulse generator (42) generates the base series of pulses synchronised with the bit slicer (38) and firstly this base series is modified by a compensation pulse generator (44) to add (or subtract) an increment from each of the weighted series of pulses. A second compensation is made for the transient effect itself being a function of the number of LEDs (10₁ ... 10 x ) to be turned on for any strobe pulse (S). To this a counter (46) connected to the bit slicer (38) provides a count (p) of the number of 1's which is further used by the compensation   pulse generator to modify the actual duration of the strobe pulses (S). All these operations may be done by means of software control. In particular the compensation pulse generator may use a look up table of strobe pulse durations covering both the weighted base pulse durations and the number (p) of LEDs turned on. The look up table may be calibrated to the individual LED array (10). The compensation technique may also be applied in other printing arrays, such as those using liquid crystal shutters. These have turn-ON transients although the number-on effect here is small.

One of the selected data operands comprise one or more fixed point values. The graphics execution unit (30) adds each of the one or more fixed point values to generate an intermediate result. When the graphics execution unit (30) detects that the addition caused an overflow/underflow condition to occur, a saturation value is substituted for the intermediate which caused the overflow/underflow condition, thereby forming a result operand. The result operand is transferred to the general register file (34).
