Patent EP-0392831-A2 (EP)
Inventor: WIRTH WILLIAM FREDERICK
IPC: G05F1/613
Filed: 1990-04-11
Abstract: In response to an input signal (at 14), a gate drive circuit for an insulated gate bipolar transistor (13) initially drives the gate to a first voltage potential which causes the transistor to partially turn on. When the transistor saturates (V₃₈ approximates V ce ) its gate drive voltage is increased (Q₃ shorts 30) to increase the conductivity of the transistor and reduce its saturation voltage drop. If, however, a load (10) coupled to the transistor is short circuited (V₃₈ approximates V₁₂) the transistor will never reach saturation and will remain partially turned on at a point where it has increased short circuit current handling capability. In addition, once the transistor has been fully turned on, should a short circuit load condition occur, the transistor will drop out of saturation causing the drive circuit to reduce the gate voltage (Q₃ off) to increase the short circuit current handling capability of the transistor. The transistor can thereby withstand the short circuit current for a longer time until a current sensor (11) acts (through 16) to turn off the transistor.

Abstract: There are disclosed a class of halogen-ended poly­alkylene glycols and halogen-ended polyolefins (II) which are copolymerizable with polyarylene sulfides or sulfone-­based polymers can be easily produced. These halogen-ended polymers may be readily copolymerized with polyarylene sulfides or sulfone-based polymers to provide polyphenylene sulfide copolymers (I) exhibiting increased crystallization speeds. These high crystallization speeds enable the copolymers to be molded in a low-temperature mold, for example, at 100°C or less, while providing fully crystal­lized moldings having excellent heat resistance properties.

Abstract: Laser etching of a substrate (28) in a liquid (12) is accomplished by laser induced sonic cavitation at the substrate surface. The preferred substrate (28) is laser (22) energy absorbing and has a finite melting temperature. The preferred liquid (12) is an organic or inorganic inert liquid which does not chemically react with the substrate (28) at room temperature. The laser (22) is preferably a copper vapor laser but a chopped beam cw argon ion laser or a YAG laser adjusted to a low power output sufficient to avoid the formation of a recast layer can also be used. The laser (22) parameters are adjusted for causing the growth and collapse of bubbles at the substrate surface. The laser etching has particular application in the fabrication of rails (46) in magnetic head sliders and dicing of Al₂O₃-TiC, TiC, SiC, Si/SiO₂, and laser energy absorbing metal and metal oxides.

Abstract: A system to measure time based on the output of a plurality of clocks employs a common oscillator, rather than a frequency synthesizer. Phase differences between a plurality of clocks are measured by mixing the output from each clock with the output of the common oscillator and detecting the zero crossing of each of the resulting beat signals. The zero crossings are counted and used to start and stop time interval counters, which count the time intervals between zero crossings of the beat signals from different clocks. The output of one of the clocks is used to provide a time base. The output of the first clock is input to a divider, and the divided signal used to start the first of the time interval counters. The number of zero crossings of the divided signal are also counted so that the relative frequency of the common oscillator can be determined. The output of the divider can be synchronized with an external clock.

Abstract: The system was a decision point designator exclusively for designating a decision piont (Pd) at its corresponding coordinate position in a coordinate region of image pattern reproduction in divisional coordinate regions. This action occurs when an extracted decision point, based on region decision data obtained by region decision means, is located in a region of a first kind. The system exclusively designates a decision point, at the scan starting point of a coordinate region of image pattern reproduction, when the extracted decision point (Pd) is located in a region of the second kind, and designates no decision piont when the extracted decision point is located in a region of the third kind. A shading of image dots is carried on the basis of the designation by the decision point designation means.

Abstract: An arrangement for detecting an error in writing data into a memory is disclosed. A data flow direction controller is responsive to a control signal applied thereto and allows data to be written, via a data terminal, into the memory during a preset time duration of a write cycle. The controller then steers the data, which corresponds to the data stored in the memory and which appears at the data terminal, to a data comparator in response to an error check timing signal which appears during a second preset time duration of the write cycle. The data comparator is therefore supplied with the original write data and the data already stored during the presence of the error check timing signal and produces a signal indicative of the error during the second preset time duration, in the event that the original write data does not coincide with the data indicative of what has been stored in response thereto.

Abstract: A memory subsystem is provided which uses memory devices having known bad bits. In order to prevent memory storage errors from occurring in the subsystem, error detection and correction circuitry is also provided. The error detection and correction circuitry is wholly contained within the memory subsystem, and is not visible beyond its boundaries. The error detection and correction circuitry can correct data stored in the array even when one of the bits within the array is permanently nonfunctional. Therefore, although data is incorrectly stored into and read from the array, these errors are corrected, and only accurate data passes beyond the boundaries of the memory subsystem.

Abstract: The electromotive adjustable resistor of present invention comprising,

   a first gear shaft having a first worm wheel and a first cylindrical gear fixed on it, said first worm wheel engaging with the first worm gear, 
   a second gear shaft having a second cylindrical gear and a second worm gear fixed on it, said second cylindrical gear engaging with the first cylindrical gear,

   a second worm wheel assembled concentrically around the adjusting shaft of the adjustable resistor, said second worm wheel engaging with the second worm gear, 
   means which transmit the rotational torque of the second worm wheel to the resistance adjusting shaft of the adjustable resistor. 
     That is, the gear train of the electromotive adjustable resistor of the present invention comprises two worm gear engagements and a sylindrical gear engagement. A sylindrical gear engagement makes the space between the resistance adjusting shaft and the motor shaft along the axis of the both shafts. 
     So that the axis of the both shafts can be coinside or nearly coinside with, in compliance with the design request, without interference between them. 
     This makes the width W of the electromotive adjustable resistor smaller, and makes the space on the circuit board occupied by it also smaller compared with the conventional type which is not able to coinside the axis of the both shafts.
