    Abstract: A mask for use with a sample preparation apparatus that prepares an ion-milled sample adapted to be observed by an electron microscope is offered. It is possible to prepare the sample having a desired cross section by the use of the mask. The mask, which defines the boundary between irradiated and unirradiated regions on the sample surface, has an edge portion having an increased thickness compared with the other portions. When the edge portion of the mask is etched, the original shape is almost maintained. Thus, the side surface of the mask is kept on the center axis of the ion beam.

  • Patent number: 6881330
    Abstract: A two-stage, retrofit filter is adapted for use with an electrical discharge machine (EDM) includes nested inner and outer filtering elements that may be placed as a unit in the same tank and over the apertured standpipe used for a one-stage filter, such that the fluid to be filtered now flows through each of the multiple filter elements. The retrofit EDM filter may be configured for flow in either direction, though the usual arrangement is one whereby the fluid being filtered flows up through the bottom of the tank, out the apertured standpipe, and into the inner filter element. Preferably, the filter elements are cylindrical, pleated elements composed of a technical grade filter paper. In the preferred embodiment, a pressure-operated release valve is provided in conjunction with the inner filter, such that when a predetermined pressure is reached due to the entrapment of contaminants by the inner filter, the valve opens to allow the fluid to be filtered to flow through the outer filter.

  • Patent number: 6882104
    Abstract: Electroluminescence elements mounted on a substrate of an OLED display device are sealed by a protective film made of synthetic resin with chemical reaction curing in place of a sealing can. The protective film is formed such that a thickness thereof is equal to or larger than a thickness of the substrate. Alternatively, the protective film is formed by laminating a plurality of resin films which differ in one of the water absorption ratio, the elastic modulus and the hardness. With respect to the protective film which is formed of a plurality of laminated films, compared to the protective film at the electroluminescence element side, the protective film which covers the former protective film has the water absorption ratio, the elastic modulus or the hardness larger than the water absorption ratio, the elastic modulus or the hardness of the former protective film.

  • Patent number: 6880786
    Abstract: An apparatus and method to improve the safety of static line parachute jumping are disclosed. According to the method, a safety device situated on a jumper continuously or periodically senses the distance of the jumper from the jumping platform (e.g. an aircraft). The safety device compares this distance to a predetermined distance threshold. When the distance between the jumper and the jumping platform reaches or exceeds the predetermined distance threshold, the safety device enables the reserve parachute deployment device which automatically deploys the reserve parachute if at such time the jumper's rate-of-descent is at or greater than a predetermined rate-of-descent threshold. Thus, the apparatus enables its reserve parachute deployment portion when the jumper is at least a predetermined distance from the jumping platform.
