Abstract: To improve the planarisation and the reliability of low-resistance conductor tracks, tungsten is used as via filler (6, 16) and metal silicides as interlayers (5, 9, 19) in the multilayer interconnection of integrated semiconductor circuits having at least two metallisation levels (8, 18) consisting of aluminium or an aluminium compound. The metallisation system according to the invention contains a nucleation layer (7, 17) preferably consisting of titanium/titanium nitride as lower layer for each metallisation level (8, 18), the resistance of the aluminium layers (8, 18) to electromigration thereby being increased, and a layer (9, 19) preferably consisting of molybdenum silicide as top layer for each metallisation level (8, 18), the low resistance of the metallisation (8, 18) thereby being improved. In addition, the sandwich-type metallisation structure improves the planarity and the thermal stability of the circuit. Since the number of metallisation layers (8, 18, 28) is optional, the invention can be used for VLSI circuits.

Abstract: A heart pacemaker comprising means (3,5) for sensing electrical events in the atrium and ventricle of a heart; means (11, 13) for pacing the ventricle in response to sensed atrial events; and means for selecting a value of a ventricular rate limit which defines the maximum rate at which the ventricle can be paced comprises means (11) for selecting a value for a VA time period and for timing the period from a sensed or paced ventricular event; means (15, 17) for pacing the atrium if an atrial event is not sensed within said VA time period; and means for increasing the VA time period by a predetermined VA amount when the ventricle is paced at said ventricular rate limit. The pacemaker enhances the synchronization of ventricular pacing to natural atrial events by defining an extended VA interval when the ventricle is paced at the ventricular rate limit.

Abstract: A signal value on the basis of a lower wheel speed is compared with a signal value on the basis of a high wheel speed and, when the difference therebetween is larger than a predetermined value, a higher vehicle speed of two previously estimated vehicle speeds is used for anti-lock control and a reference value with which a wheel speed will be compared is derived from such vehicle speed. Thus, a range of condition for judging that wheels of a vehicle are about to be locked is enlarged.

Title: Self-correcting semiconductor memory device and microcomputer incorporating the same
IPC: G11C29/00
Filed: 1988-08-31
Granted: 1993-01-13
Abstract: In a nonvolatile memory device or a microcomputer with a nonvolatile memory, data errors arising from loss of charge in the floating gates of memory cells are detected and corrected by applying two different sense voltages to the memory cells and comparing the outputs. Instead of using a cumbersome error-correcting code, this error-correcting scheme requires only one parity bit per word, yet it can detect and correct errors in any odd number of bits. Benefits include reduced chip size and longer life for electrically erasable and programmable memories.

Granted: 1992-12-16
Abstract: An analytical method for determining the relative amount of a particular hemoglobin derivative, e.g., glycated hemoglobin, in a blood sample wherein the amounts of both total hemoglobin and the hemoglobin derivative are measured and related mathematically, e.g., as a percentage. The blood sample is treated with the combination of a thiocyanate salt and an oxidant to denature the hemoglobin in the sample and to convert hemoglobin to met-hemoglobin. Met-hemoglobin is measured spectrophotometrically to give the amount of total hemoglobin present, and the denatured hemoglobin derivative can be distinguished and measured by immunoassay. The presence of the oxidant in the denaturant solution has been found to increase the rate of denaturation of hemoglobin thereby reducing the overall assay time and improving the reliability of the determination.

Abstract: A single-housing stepper motor is disclosed comprising a rotor (14) and stator (16) both mounted in a single housing (10) (which may be a part of the base casting) the bearings (40, 42) supporting the rotor for rotation within the housing both being located on the rotor shaft on the same side of the rotor adjacent one another, the opposite end of the single housing being covered with a sealed plastic cover (44). The lamination stack (18) that forms the stator is piloted by machined surfaces (30, 32) into a high tolerence fit within the housing (10), and clamped in place with a simple wave washer/snap ring combination (66, 68). The stator laminations are designed with a decagonally interrupted periphery which can be used without changing the area of the poles (20), and allow space for the wires to the poles to be lead out past the lamination stack. A sealing plastic cover (44) is provided with a special pressure finger (60) to hold the wires (36) running to the stator coils away from the sharp edges of the stack wave spring and snap ring; the cover is also specially designed to capture the wires to relieve the strain on the wires. Alternatively (Fig. 5), the bearings (104, 106) may be located on opposite sides of the rotor (14), the stator (16) is piloted into a precisely aligned position on an inner wall of the housing adjacent the front bearing (104), the other end of the stack being held in place by a bearing holder (116) interposed between the rear bearing (106) and the edge of the stator (16), the holding forces being precisely defined to accurately align the stator with the rotor of the stepper motor. The entire assembly, including the rear bearing, bearing holder and stator support, as well as the stator is held together with a star-shaped spring (15)) comprising a plurality of fingers (106A-D) that slide into and rotate within slots (158A-D) in the housing in a bayonet arrangement. These slots allow insertion of the star-shaped spring under pressure, and rotation under pressure within the groove (160) to a seated position. The same groove then accepts the (160) to a seated position. The same groove then accepts the encapsulating plastic cover (170), preferably inserted through the same openings as the bayonet arms of the spring, though being rotated in the opposite direction.
