  • Patent number: 7017593
    Abstract: A micro device in which a functional element can be moved between an operating position and a waiting position by the displacement of support means coupled to a substrate. The micro device has a cantilever structure in which one end of support means is made a fixed one fixed to the substrate and the other end to which an active element is provided is made a free end. A spring portion is provided to at least part of the support means, and thus the active element can be greatly displaced by a small stress.

  • Patent number: 7013902
    Abstract: A mobile cleaning workbench that may be used for manually washing equipment components, parts or other articles is provided. The cleaning station provides a source of water or other cleaning liquid for use in the washing of an article in a wash basin. A drain is provided for removal of cleaning liquid from the wash basin. Since some chemicals produce vapors which are emitted as chemical-laden articles are moved about, alternative embodiments of the invention include a ventilation exhaust system that removes the vapors from the washing area and transfers them to a remote location via appropriate ducting.

  • Patent number: 7000620
    Abstract: A float mounting plate is provided for a dishwasher to limit the level of water in the dishwasher tub. The float has a stem extending downwardly through a stand pipe in the bottom of the tub and into a switch bracket which houses the water level control switch. A tab is provided on the switch bracket which is adapted to extend around the float stem, thereby slidably retaining the retainer ring of the stem for engagement and disengagement with the switch, and limiting lateral or horizontal movement of the stem. In one embodiment, the tab is integrally formed with the bracket, with a living hinge allowing the tab to pivot between open and closed positions. In a second embodiment, the tab snap fits onto the bracket to capture the float stem.

  • Patent number: 6994098
    Abstract: The invention relates to a method for operating a dish washing machine (1) comprising, inside a washing tub (3), at least one spraying device (6), to which a pump (8) supplies washing liquid and which is provided with spraying openings (5). The washing liquid is sprayed into the washing tub (3) via said spraying openings (5). The aim of the invention is to be able to easily detect when the spraying openings (5) become clogged. To this end, the pump (8) is switched on and washing liquid can be supplied even when the washing tub (3) is accessible. In doing this, the flow rate of the washing liquid through the spraying openings (5), however, is simultaneously reduced to such an extent as to prevent washing liquid from spraying out of the open washing tub (3) and into the free surrounding area.

  • Patent number: 6983754
    Abstract: A support structure and method, designed to maintain a resealable plastic bag in an open position within a dishwasher through the washing and drying cycles, has at least two vertically extending support and restraining straps that may be engaged with like straps to form a resilient support framework. A plurality of mating dimples and protrusions offer controlled size adjustments, while maintaining the reliability of the structure. The structure is readily collapsible to a flat and compact structure prior to purchase and when not in use, and includes features to engage with the rack in the dishwasher to prevent the support and bag from being substantially relocated during the wash process.

  • Patent number: 6949145
    Abstract: The present invention is directed towards the use of a reactive gas or vapor of a reactive liquid prior to or in combination with cryogenic cleaning to remove contaminants from the semiconductor surfaces or other substrate surfaces requiring precision cleaning. The reactive gas or vapor is selected according to the contaminants to be removed and the reactivity of the gas or vapor with the contaminants. Preferably, this reaction forms a gaseous byproduct which is removed from the substrate surface by the flow of nitrogen across the surface.

  • Patent number: 6945257
    Abstract: Hollow porous fibers containing adhered contaminants are cleaned to remove the contaminants by backflushing a liquid to fill the pores, and adding a flow of gas so as to form a two-phase mixture of gas and bubbles of liquid that can scrub the fibers, loosening the contaminants and allowing them to be flushed from the hollow fibers. The method is particularly useful for cleaning hemodialyzers used for dialysis and hollow fiber modules used in water treatment and separations. The two phase flow method is specifically effective in cleaning piping systems having high length to diameter (l/d) ratios.

  • Patent number: 6942737
    Abstract: A substrate is supported at a plurality of edge positions thereof, to be in horizontal posture, by support pins erected on a spin chuck. A two-fluid nozzle is fixed to a position spaced from and directly over edges of the substrate to clean the edges. Substantially simultaneously therewith, a cleaning brush cleans the substrate while swinging over, in direct contact with, areas other than the edges of the substrate. The two-fluid nozzle delivers mist in a small quantity and in minute droplets. The mist is restrained from rebounding and scattering from the plurality of edge positions supported by the support pins of the spin chuck. The mist may be supplied to clean such positions.
