Patent EP-0161983-A2 (EP)
Inventor: MING LIN CHONG
IPC: H01L23/485
Filed: 1985-05-02
Abstract: An input protection arrangement for diverting current from high voltages due to, for example electrostatic discharges into a bonding pad of an integrated circuit chip. The chip has a bonding pad connected to a conducting path and to a source or drain region of an insulated gate field effect transistor, the other region being connected to a power bus on the chip. The conducting path runs between the source and drain regions and operates as the gate terminal of the transistor. The conducting path is insulated from the surface of the chip by a field oxide insulating layer of a substantially uniform thickness to prevent rupture of the oxide between the gate and the source and drain regions in the event of high- voltages. The source and drain regions include regions of conventional doping levels having depths corresponding to the depths of the other corresponding regions on the chip, surrounded by large wells of lower doping levels. The input pad is separated from the chip substrate by an insulating oxide layer and by a doped well of the same conductivity type as the source and drain regions of the transistor to reduce the input capacitance and prevent punch through from the pad to the substrate.

Abstract: In this method, the mercury or the mercury alloy is placed in one or more electrolyte vessels (1) and electrolytically enriched with the corresponding metal from the salt solution so that one or more mercury-metal suspensions are formed. For this, the metals in the metal salt solutions are elements which themselves, either alone or as a mixture or alloy, do not form any alloy with mercury, are wettable by mercury and have a high resistance to oxidation. The mercury-metal suspensions formed are then mixed in defined ratios, tempered and the excess mercury not absorbed is filtered off. The remaining filter cake is passed into the hole in a steel cylinder and the remaining excess mercury is pressed out under high pressure so that a brittle pressed piece is produced, the powder from which is then formed into the pressed parts that are used as the storage elements. <IMAGE>

Abstract: A one-piece molded closure of plastic which threads onto a container with a fairly specific exterior configuration and provides a combination such that when the closure is unthreaded, a tamper-indicating ring becomes separated from the lower end of the closure skirt. The indicating ring or band is joined to the closure by frangible bridges and a flexible stop ring is formed within the band and extends inwardly and upwardly when the closure is applied to a container finish. The container finish has a first radial bead and an inwardly tapering side wall surface therebeneath which leads to an abrupt, inwardly extending ledge. The flexible stop ring rests on the tapered surface, when the closure is applied. After closure removal, the stop ring and band drops below the ledge indicating that the closure has been removed.

Abstract: A quadruple voltage regulator (20, 40, 60, 80), having four independently controllable power circuits in a single integrated circuit, comprises a current sensor (24, 44, 64, 84) for each of the power circuits. Each current sensor provides an active output signal when the magnitude of the current provided by the corresponding voltage regulator exceeds a selected limit. A single temperature sensing device (12) monitors the temperature of the integrated circuit and generates a control signal when the temperature exceeds a selected threshold temperature magnitude. The output signal of each current sensor is independently combined with the control signal from the temperature selector to disable the corresponding voltage regulator circuit when the temperature exceeds the threshold magnitude coincident with an excess current provided by the regulator.

Abstract: An image processing apparatus includes a dither processor (14), which converts an electrical signal - (12) representing a continuous-tone input image into a binary image signal (16) by a dither method using a dither matrix. The binary image signal (16) is stored in a memory (18), and supplied to a pixel-density conversion processor (20), which converts a pixel-density of the binary image signal at a predetermined ratio, and generates a converted image with the pixel coordinates as defined by the conversion ratio. A pixel coordinate calculator (22) calculates a coordinates position of each pixel of the converted image in the binary image, and selects a fiducial pixel. Reference pixel selector (24) defines a window area on the binary image containing the fiducial pixel and corresponding in size to the dither matrix size, and extracts reference picture elements in the window area. A calculator (26) calculates an average image-density of the reference picture elements and generates density data, which is binarized by a second dither processor (28) by using a second dither matrix.

Abstract: In a high-speed arithmetic processor (30), a first number that has an absolute value that can exceed one is multiplied by a second number that has an absolute value not exceeding one. If the first number exceeds one it is divided into an integer and a part having a value less than one. The second number is accumulated as an addend a number of times equal to the integer to produce a sum. The second number and the part of the first number having a value less than one are supplied to a multiplier (43) to produce a partial product. An adder (45) adds the partial product to the sum, thereby obtaining a final product of the first and second numbers. The multiplication is thereby performed in a number of steps which is minimized and never varies, regardless of whether the absolute value of the first number is, for example, less than one, at least one but less than two, or at least two but less than three. This speeds up the arithmetic processing and simplifies the programming therefor.

Abstract: Headstocks for lathes comprise a gear mechanism which comprises at least one drivable input shaft and, for branching the power output, two output shafts for the drive of a face plate provided with a rim gear. The two output shafts have a first pinion pair, meshing with intermediate gears of an intermediate shaft, for the drive of the output shafts as well as a second pinion pair meshing with the rim gear of the face plate. In such headstocks, the drive is not completely free of backlash, which has an adverse effect on the machining of workpieces. In the invention, the two pinions of the first pinion pair are designed with helical tooth systems running in opposite directions, and in fact with an appropriate helical tooth system of the meshing intermediate gears. The drive of the headstock can be arranged to be free of backlash by a selective axial displacement of the intermediate shaft carrying the intermediate gears. <IMAGE>
