  • Patent number: 6633173
    Abstract: A circuit is tested for latch-up by scanning an optical beam across the surface, supplying power to the integrated circuit, monitoring the power of the power supply, and detecting latch-up in the integrated circuit by capturing an image of the integrated circuit when the power reaches a predetermined threshold. The captured image is compared with a baseline image to determine where latch-up occurs in the circuit.

  • Patent number: 6277246
    Abstract: A system and method for purifying liquefied corrosive gases of metallic impurities is described. The principle for this purification method relies on vapor-phase transfilling the vapor phase from a source container into a receiving container. This method has been observed to decrease metal concentrations by a factor of at least 1000 and decreases the metallic impurity levels in the resulting condensate. The vapor transfer is accomplished by controlled differential pressure rather than mechanical pumping, thereby generating no particle or metal impurities.

  • Patent number: 5981089
    Abstract: A ferrous alloy is formed with a Fe--Cr stainless steel having a Vickers hardness of 400 or more as a substrate and a Fe--Al diffusion layer having a thickness of 2 to 50 .mu.m. The diffusion layer contains at least 90 vol % of an intermetallic compound of Al and Fe relative to a total volume of the diffusion layer. The Al content included within a depth of at least 2 .mu.m of the diffusion layer is 35 to 65% by weight based upon total weight of a region of the diffusion layer ranging up to the thickness of at least 2 .mu.m. It is preferred to use as the substrate a precipitation-hardening stainless steel comprising 66 to 81.9 wt % of Fe, 15 to 20 wt % of Cr, 3 to 13 wt % of Ni, and one element selected from 3 to 6 wt % of Cu, 0.5 to 2 wt % of Al, and 0.01 to 0.2 wt % of a total of C and N, or a high carbon stainless steel comprising 73 to 89.9 wt % of Fe, 10 to 19 wt % of Cr, 0.1 to 1.2 wt % of C, and less than 3 wt % of Ni.

  • Patent number: 5821508
    Abstract: An electronic voting system is disclosed that provides voters who may be blind, illiterate, or conversant in a foreign language, with a means to enter selection information without having to rely on visually perceptible information. In accordance with exemplary embodiments, candidate and/or referendum information is supplied audibly such that the voter can respond to selection options by speech input, actuating a button on a hand-held device, or other mechanism that permits the voter to indicate his or her selection preferences without having to visually interact with the system. The system provides an audio confirmation of the voter's selection. Such a system allows the aforementioned individuals to vote in confidence without assistance.

  • Patent number: 5775380
    Abstract: After a warp beam on a loom is used up, its old warp threads are separated from a material being woven on the loom. The used-up beam, together with its residual old warp threads, is then mounted on a transport device and moved away from the loom. A winding element rotatably mounted on a maintenance device is positioned adjacent the transport device. Leading ends of the old threads are affixed to the winding element and separated from the used-up beam, whereafter the used-up beam is replaced by a new beam. Leading ends of new threads on the new beam are attached to trailing ends of respective ones of the old threads, whereafter the winding element is rotated to wind-up the old threads and parts of the new threads, while pulling the new threads through a loom device (such as a warp stop motion device, and/or a shedding device, and/or a weaving reed) carried on the transport device. Then, the winding element is rolled along a guide surface to a removal device.

  • Patent number: 5722078
    Abstract: A method and system for locating control channels, particularly digital control channels, are described. By grouping the channels which are candidates for carrying supervisory messages in blocks indicative of their relative likelihood for being used as control channels, a mobile station can begin its search for a control channel with channels which are most likely to actually be control channels.

  • Patent number: 5525675
    Abstract: Described is a thermoplastic elastomer comprising (A) 10-90 wt. % of polypropylene having substantially a syndiotactic structure, and (B) 90-10 wt. % of an ethylene-propylene-nonconjugated diene copolymer rubber and/or ethylene-propylene copolymer rubber, said (B) having been partially crosslinked. The elastomer according to the present invention is useful for obtaining formed products, particularly automotive bumper fascias, automotive mud guards and automotive trim skin material, which are excellent not only in flexibility, rubber elasticity and mechanical strength but also in external appearance and touch, and are substantially free from bleeding and fogging.

  • Patent number: RE37204
    Abstract: A support member preferably made of a metal such as cold rolled steel is disposed in a looped configuration and is provided with a gap. A transducer member preferably made of a piezoelectric material such as a ceramic is disposed within the support member. The transducer member is provided with a gap at a position corresponding to the gap in the support member. A closure member made from a suitable springlike material such as an alloy steel is attached to the opposite ends of the support member at the position of the gap as by welding. The closure member extends in a U-shaped configuration into the looped configuration (in section) defined by the support member and the ceramic member. The axial length of the closure member defines the bandwidth of the frequency vibrations generated by the transducer member.
