Abstract: A surface acoustic wave device which can operate at higher frequency range is provided by making narrower the electrode width while not degrading reliability of the device. The surface acoustic wave device includes a piezoelectric body 3 and interdigital electrodes 2a and 2b in close contact with the piezoelectric body 3, and the interdigital electrodes 2a and 2b are formed by using focused ion beam. In order to increase the frequency of the device, the piezoelectric body 3 may be formed on a substrate 1 formed of, for example, diamond.

Abstract: A track following system for maintaining a read gap substantially centered on a data track by moving the read gap perpendicular to the direction of the data track. This moving of the read gap is performed to compensate for any original misalignment between the read gap and data track and also to compensate for any wander or movement of the data track to a misaligned position with respect to the read gap. The write gap is used as a source of position information to keep the read gap correctly positioned over the data track. During a track following operation, the write gap circuitry is operatively connected to a track following circuit. Several samples of data signals received by the write gap are analyzed by the track following circuit. The track following circuit operates to compare (24) a first sample (20,22) of such data signals with a second sample (21,23). A positioning device (13) moves the read gap in a direction determined from the result of this comparison and also from the last direction in which the read gap was moved.

Abstract: The invention relates to a process for improving the fatigue strength under reversed bending stresses of semi-finished copper alloy products. In this case, the copper alloy is melted, a preform is produced and the end form is obtained from the preform by usual steps of hot- and cold-forming. In order to improve the fatigue strength under reversed bending stresses as compared with conventionally manufactured semi-finished products, it is proposed according to the invention that the preform is produced by the process of spray-compacting and that a copper alloy is used which contains nitride-forming elements (such as, for example, zirconium, titanium, magnesium, chromium, aluminium, manganese, boron, niobium, tantalum, vanadium) individually or in combination in a concentration range of from 0.001 to 3.0% in total.

Abstract: Disclosed is an integral one piece plastic fastener (10) for securing belt ends together. The fastener has upper and lower plastic plates (14, 24) clasped to a belt end (20) with integral, hollow rivets (12) projecting from the upper plate (14) through openings (22) in the bottom plate (24) and with hollowed ends of the rivets deformed to form rivet heads (42) for maintaining clasping of the plastic plates on the belt end. Also disclosed is a rivet head forming tool which smoothly forms rivet heads by a spinning process in which a rotating tool (40) is forced against the hollow end of the rivet and spun with sufficient velocity and applied with a high force to create a sufficient heat and pressure to cause the end wall of the rivet to curl and turn over radially outwardly to form a rivet head tightly pushing against the lower plate of the fastener.

Abstract: Specific mixtures of tocopherol homologs exhibit surprisingly improved antioxidant effects in mint oil and mint-flavored chewing gum compositions. The mixtures of homologs fall within the range of 7-15% by weight alpha tocopherol, 45-70% by weight gamma tocopherol and 20-35% by weight delta tocopherol. Homologue mixtures within this range are superior to the constituent homologs used alone, and to other homologue mixtures, in terms of antioxidant effects. The compositions of the invention facilitate the replacement of controversial synthetic antioxidants currently used in mint oil and mint-flavored chewing gum, with naturally occurring tocopherols.

Abstract: A coating method reduces the non-uniformity of a coating film at an end portion of a workpiece to thereby improve the coating quality. In spraying coating material from spray guns (10) along an end portion of a coating surface of a workpiece (5), the amount of the coating material emitted from the spray gun is reduced to prevent an increase in thickness of the coating film at an end portion of the workpiece. In an alternative, and in the case of electrostatic coating, the applied electrostatic voltage may be reduced or nullified in spraying the coating material to achieve the same effect.

Abstract: Dans la fabrication conventionnelle, l'épaisseur des plaques d'acier (16, 16') est souvent déterminée par la section de métal nécessaire aux zones de soudure. L'appareil (10, 10') et le procédé de la présente invention surmontent ce problème grâce au formage sélectif d'un bord plus épais (12, 12') le long de l'arête (14, 14') d'une plaque d'acier plus fine (16, 16') qui peut maintenant être limitée à l'épaisseur nécessaire pour résister aux sollicitations de la fabrication. Ledit bord plus épais (12, 12') est produit en faisant passer une plaque (16, 16') placée sur une table (20, 20') à travers un appareil de formage (22, 22') doté d'un rouleau de formage (58, 58'). Ladite table (20, 20') est mobile dans une direction oblique par rapport à la plaque, si bien qu'il est possible de produire des bords plus épais de forme variée. L'appareil de formage (22, 22') et la table (20, 20') sont commandés automatiquement de manière à produire un bord plus épais (12, 12') d'une forme désirée en interrompu ou en continu le long d'une arête linéaire ou non linéaire (14, 14') de la plaque (20, 20').

Title: Differential latching inverter and random access memory using same.
Inventor: VINAL ALBERT W
IPC: G11C11/41
Filed: 1992-05-28
Abstract: A differential latching inverter uses a pair of cross-coupled inverters having a skewed voltage transfer function to rapidly sense a differential signal on a pair of bit lines in a random access memory and provide high speed sensing during a read operation. The differential latching inverter may also include a pair of symmetrical transfer function output inverters and additional pull-up circuits to enhance high speed operation. The differential latching inverter may be used in a memory architecture having primary bit lines and signal bit lines, with a differential latching inverter being connected to each pair of signal bit lines. The primary bit lines and signal bit lines are coupled to one another during read and write operations and decoupled from one another otherwise. The read and write operations may be internally timed without the need for external clock pulses in response to a high speed address change detection system, and internal timing signals generated by delay ring segment buffers. A high speed, low power random access memory may thereby be provided.

Abstract: Procédé de préparation et de récupération de nitrure métallique à partir de leurs alliages ferrométalliques et de leurs alliages métalliques de nickel. Les étapes du procédé consistent à utiliser du nitrure de niobium préparé à partir d'alliages de ferroniobium qui sont d'abord hydrurés pour obtenir un produit friable triturable. L'alliage hydruré est ensuite chargé par une trémie d'alimentation (2) dans le réacteur (9). L'hydrure de ferroniobium est ensuite nitruré au fur et à mesure que l'on introduit un gaz contenant de l'azote dans la cuve de réaction (9) à travers l'orifice d'admission (4). Les conditions de pression de la cuve de réaction (9) sont régulées par un conduit (21) en communication avec la soupape de libération de pression (20) et l'entrée (15) ce qui éventuellement, amène une suppression de gaz inerte telle que l'hélium. Les conditions de l'étape de nitruration sont régulées afin de former des phases distinctes de nitrure de fer et de nitrure de niobium, respectivement.
