Abstract: A silicon wafer-cleaning apparatus enables the two sides of silicon wafers (35) to be uniformly etched with a high degree of purity, permits rising processing to be executed in the same chamber as that in which the etching is executed, prevents particles of contaminating substance from adhering to the silicon wafers when the silicon wafers have just been etched, and further prevents an oxide film from being excessively formed on the silicon wafers. The cleaning apparatus is made up of a chamber (1) which is vertically divided into a mist-generating chamber (3) and a processing chamber (4) by a partitioning wall having a communication section, a opening/closing mechanism (20) including a shutter (21) for closing the communication section of the partitioning wall, a high-frequency oscillation member (8), attached to the chamber, for generating mist of an aqueous hydrofluoric acid solution in the mist-generating chamber (3), a high-frequency oscillator (9) for supplying high-frequency power to the high-frequency oscillation member (8), a conveyance mechanism (32) for conveying a cassette, in which a plurality of silicon wafers (35) are held in an upright state, to the processing chamber, a plurality of gas-ejecting nozzle members (29, 38), attached to the chamber and the shutter, for ejecting a gas toward regions between the silicon wafers held in the cassette, pure water-spraying nozzle members (41), attached to the chamber, for spraying pure water toward regions between the silicon wafers (35) held in the cassette, and a gas exhaust member (46) arranged inside the processing chamber to be lower than the cassette conveyed by the conveyance mechanism.

Title: Reduced calorie potato chips and other low moisture fat-containing foods having less waxiness and improved flavor display.
Inventor: YOUNG JERRY DOUGLAS
IPC: A23L19/18
Filed: 1991-04-08
Abstract: Reduced calorie potato chips, and other low moisture fat-containing foods having less waxiness and improved flavor display are dislosed. These benefits are typically obtained by applying to the surface of the potato chip, or other food, fat compositions having certain thixotropic areas that correlate to reduced waxiness impressions. These fat compositions comprise a nondigestible fat component, and optionally a digestible triglyceride fat or oil. The nondigestible fat component comprises a nondigestible oil and preferably low levels of certain solid polyol fatty acid polyesters having ester groups comprising combinations of unsaturated (C12 or higher) and/or short chain (C2-C12) saturated fatty acid radicals and long chain (C20 or higher) saturated fatty acid radicals. The solid polyol polyesters bind the liquid oils and thus control or prevent passive oil loss, even at relatively low levels.

Abstract: A printed circuit contact system for use in high speed digital applications includes a generally tapered slotted socket made of beryllium copper or other conductive spring material. The socket has a wave-like configuration which forms a series of outer contact portions which alternate with increasingly smaller inner contact portions. Insertion of an appropriately dimensioned pin through the socket causes engagement of the pin with at least one of the inner contact portions to radially expand the socket and force adjoining outer contact portions to abut against a sleeve lining a hole in a printed circuit board into which the socket is inserted. Expansion of the socket provides at least one portion thereof which is always under optimum load, assuring proper retention and physical and electrical contact over extended periods.

Abstract: A method for frequency-dependent, adaptive control of the damping force of an oscillation damper (dR) for motor vehicles with controllable valves for changing the damping characteristic in a multiplicity of stages is described. The controller (RG) generates a control variable portion which is dependent on the travel speed (VFahr) for the adjustment of a basic damping characteristic and generates a control variable portion which is dependent on the frequency of the excitation of the road and is calculated via the acceleration (aa) of the body and is superimposed on the control variable portion of the travel speed. The method thus offers the facility of adjusting the damping force (FD) of an oscillation damper (dR) as a function of the road state and of the travel speed (VFahr) in order to achieve a high degree of driving safety and optimum comfort. <IMAGE>
