Title: Floating fluid-operated actuator
Inventor: JORNOD EUGENE R
IPC: F15B15/14
Filed: 1992-03-23
Granted: 2002-09-10
Abstract: The piston of a reciprocating hydraulic actuator carries a pump which is driven by an electric motor and which supplies oil from the low pressure chamber of a cylinder to the high pressure chamber thereof in order to advance the piston. An exhaust valve in the piston is normally held in a closed position by magnetic force created by energizing a coil and, when closed, enables pressurization of the high pressure chamber of the cylin-der. When a second coil is energized, the magnetic field of the first coil is negated and the valve is opened by a spring to permit oil to exhaust from the high pressure chamber to the low pressure chamber and permit a second spring to retract the piston. If both the pump motor and the second coil are de-energized, the first coil keeps the valve closed and causes the piston to remain in a commanded position. The actuator may be controlled by a floating single pole, double throw switch and its piston is automatically shifted to its fully retracted position by the second spring if electrical power to the actuator is lost.

Title: Technique for manufacturing hose
Inventor: BURLETT DONALD JAMES
IPC: C08L23/16
Filed: 1992-09-16
Granted: 2001-01-16
Abstract: Hoses are often reinforced with fabric to improve their performance characteristics, such as burst strength. For instance, radiator hose used in automotive applications is generally reinforced with continuous yarn. However, it is a labor intensive process to manufacture such hoses which include fiber reinforcements. A substantial amount of material waste also generally occurs in the manufacture of such fiber reinforced hose. By utilizing the technique of this invention, hose which has a high level of burst strength can be manufactured without including continuous yarn reinforcement. This invention specifically reveals a process for manufacturing a hose which comprises (1) extruding a rubber composition into the form of a tube, wherein the rubber composition is comprised of (a) an EPDM alloy comprised of (i) standard EPDM rubber, (ii) an EPDM rubber having thermoplastic side chains grafted thereto, and (iii) dispersed thermoplastic wherein the thermoplastic is selected from the group consisting of nylons, polyesters, and polyphenylene oxides, (b) an EPDM rubber, (c) carbon black, (d) at least one curative, (e) zinc oxide, (f) a processing oil, and (g) stearic acid; (2) shaping the tube into the geometric form desired for the hose; and (3) curing the rubber composition at a temperature within the range of 130°C to 210°C to produce the hose.

Granted: 1997-11-25
Abstract: A wiring board having a wiring circuit which is reliable and which can be easily miniaturized, which is used for the production of a highly integrated, lighter, thinner, shorter, smaller and low-cost semiconductor device.  This wiring board can be sealed in a plastic package.    It comprises a metal plate (1) and a thin-film dielectric layer (2) formed on the surface of the metal plate.  A semiconductor device (8) is mounted on the surface of the dielectric layer (2) or the exposed surface of the metal plate (1). Film wirings (3), (4) and (5) are formed on the dielectric layer (2).  Each film wiring is in the form of a laminate formed by laminating, by vapor phase deposition or by plating, an aluminum conductive layer, an adhesive layer of chromium, titanium or a laminate thereof, a diffusion barrier layer of nickel, copper or a laminate thereof, and a corrosion-preventive and wire bonding layer of gold.  Such wirings may be in the form of a laminate formed by laminating an adhesive layer of chromium, aluminum, titanium or a laminate comprising at least two of them, a copper conductive layer, and a gold layer or a laminate formed by laminating an aluminum conductive layer, a barrier layer of nickel, and a gold layer.  Since the film wirings can be miniaturized easily, the density of wirings can be increased. Also, since the wirings are made of aluminum or copper, they are cheap.

Title: Heating element for an air flow heater
Inventor: EDWARDS GARY C
IPC: H05B3/16
Filed: 1993-02-02
Granted: 1998-10-06
Abstract: A heating element for an air flow comprises a channel shaped bracket including a base and side walls at right angles thereto within which is mounted a pair of mica sheets arranged parallel to the base and at right angles to the sides and connected to the sides by ribs longitudinally of the sides with transverse slots within which the sheets slide. Each sheet is wrapped with a heating wire formed into helical coils so that each side of the sheet carries a plurality of parallel helical coil portions with connecting portions wrapped over the edges of the sheet. The sheets are symmetrical and one is inverted relative to the other. Each sheet carries at ends thereof a male and a female connector of the blade and receptacle type so that the blade of one sheet engages into the receptacle of the other sheet. The connectors thus provide mechanical support to hold the sheet in spaced position and in addition provide electrical connection across the sheets so that electrical energy from supply wires is connected in parallel across the wires of the two sheets. The structure is simple to manufacture and provides a structurally rigid arrangement with high wire density leading to reduced wire temperature.

Title: Plasma-enhanced magnetron-sputtered deposition of materials
Inventor: NIEH SIMON K
IPC: C23C14/34
Filed: 1993-08-10
Granted: 1997-12-16
Abstract: Plasma-enhanced magnetron-sputtered deposition (PMD) of materials is employed for low-temperature deposition of hard, wear-resistant thin films, such as metal nitrides, metal  carbides,  and metal  carbo-nitrides,  onto  large, three-dimensional, irregularly shaped objects (20) without the requirement for substrate manipulation.  The deposition is done by using metal sputter targets (18) as the source of the metal and immersing the metal sputter targets in a plasma (16) that is random in direction and fills the deposition chamber (12) by diffusion.  The plasma is generated from at least two gases, the first gas comprising an inert gas, such as argon, and the second gas comprising a nitrogen source, such a nitrogen, and/or a carbon source, such as methane.   Simultaneous with the deposition, the substrate is bombarded with ions from the plasma by biasing the substrate negative with respect to the plasma to maintain the substrate temperature and control the film microstructure.  The substrate, metal targets, and plasma are all electrically decoupled from each other and from walls (14) of the deposition chamber, so as to provide independent electrical control of each component.  The PMD process is applicable not only to the deposition of hard coatings, but also can be applied to any thin film process such as for electrically and thermally conductive coatings and optical coatings, requiring simultaneous, high-flux, ion-bombardment to control film properties.

Granted: 1999-07-13
Abstract: In a switching system, a data bus which interconnects circuit modules, a switching network module and a control module for transporting packets between the interconnected modules. A bus interface (16) is connected to the data bus (13) for receiving a copy of every packet on the data bus. An error detector (18) determines whether the received packet contains an error, and produces an error detect signal and an error check result if the received packet is determined as having an error. In response to the error detect signal, the received packet, the error check result and time-of-day data are stored into a register (19) and transferred to one of the storage locations of a memory (20) to keep a list of error records. A maintenance station (22) reads stored error records from the memory for identifying the source of errors.
