摘要:
A rack for supporting at least one abrasive generally circular disc on a conventional display stand, wherein each disc has two faces and a continuous edge includes a pair of rack support rails which co-extend alongside one another in a spaced relation of a distance less than a diameter of the disc and at least one of the rails includes a raised ridge surface. When the disc is disposed such that its edge contacts the rails and the disc is supported by the rails, the disc is positionably retained by the ridge along a predetermined area of the rail.

A vertical ceramic wafer boat for supporting a silicon wafer having a predetermined radius “R”. The wafer boat comprises a base portion and a column rack, which extends generally vertically upwards from the base portion. The column rack includes a pair of vertical column rack supports extending generally vertically upwards from the base portion. The column rack also includes a plurality of wafer supports having a generally Y shaped cross section. The wafer supports extend substantially horizontally from the column rack supports to define a plurality of slots within the column rack sized to receive the wafer.

A cassette for supporting substrates and an elongated rib therefor is described and represents a further improvement in the previously proposed elongated rib systems of the prior art and is designed particularly to preclude deflection and dampen vibrations of loaded substrates. The elongated ribs for the cassette project from side panels utilizing an elongated rib structure including three segments; namely, a base resin body, a bar-like intermediate resin body extending from the base resin body, and a terminal resin body disposed at the forward end of the intermediate resin body. Preferably, the elongated rib structure includes a linearreinforcing member inserted fromthe base resin body to the intermediate resin body or, alternatively, from the base resin body through the intermediate resin body to the terminal resin body.

An apparatus and method for diffusion annealing impurities onto a plurality of wafers is described. A hollow wafer holder includes a plurality of first and second slots. The first slots are sized and shaped to receive a pair of wafers. The first slots are angled relative to a longitudinal axis of the wafer holder. The wafer holder is positioned at a first location within an ampoule, with a diffusion source being positioned at a second location within the ampoule. The ampoule is sealed and placed within or near a heat source. The heat source alters the physical state of the diffusion source to allow the entrained impurities to diffuse throughout the ampoule. The inclination of the first slots allows a sufficient clearance between the wafers and the ampoule to allow impurities within a gaseous diffusion source to extend throughout the ampoule. The presence of the second slots allows a more uniform diffusion of the impurities to the wafers.

A device for supporting objects for drying. This device contains a catch basin, for receiving fluid that drips off of these drying objects. Attached to the catch basin is a first adjustable rack, having a front end and a back end. The back end of the first adjustable rack is rotatably supported within the catch basin. There is also a second adjustable rack disposed in the basin. Both the first adjustable rack and the second adjustable rack are comprised of a series of parallel extending bars that are spaced apart from each other to receive a plate between these parallel extending bars. These parallel extending bars are also designed to support a series of pots on either the first adjustable rack or the second adjustable rack wherein these parallel extending bars allow water to drip down through the bars and into the catch basin. In addition, there is also an adjustable tray disposed adjacent to the adjustable racks wherein the adjustable tray is designed to support kitchen utensils and silverware in an upright manner for drying. This device can also be collapsed to allow this device to be folded up to stand freely upright on a substantially horizontal surface.

A circuit board carrier and method of using the same. The carrier allows circuit boards to be processed on lead frame-based semiconductor processing equipment. The circuit board carrier contains a structure to secure a circuit board thereto and the carrier is sized and shaped, and provided with standardized indexing holes, to allow processing of circuit boards on processing equipment configured for lead frame-based processing.
摘要:
A fixturing device which supports a substrate or a plurality of substrates in a vertical orientation during cleaning, drying, and coating processing steps while minimizing the contact surfaces between the fixture and each substrate so that a maximum of the substrate surface is exposed. The fixturing device utilizes converging support surfaces that terminate at the closest point in a gap with a distance less than the thickness of a substrate. The converging support surfaces counter surface tension, cohesion of the liquid molecules, and the adhesion of the liquid molecules on the surface of the fixturing device. The gap in the converging support surfaces prevents the fixturing device from retaining liquid at the interface of the substrate and the fixture. In conjunction, the contoured passages enhance the drawing of liquid away from the fixturing device and prevents pooling and staining the substrate. This fixturing device can be implemented in plurality to form two or three dimensional arrays to support a plurality of substrates. The fixturing device can be designed to interface with substrates through an internal aperture, an outer perimeter, or as an end effector on a gripper.

The present invention discloses a cassette for loading glasses, the cassette capable of preventing the bending phenomena of the glasses due to its weights, and capable of discharging the static electricity formed on the glasses and cassette, and capable of preventing the drifting away of the glasses via front side of the cassette. The cassette includes a plurality of side plate which are parallel to each other and having a plurality of slot for loading the glasses therein. And a top plate is connected to one ends of the plurality of side plate and a bottom plate is connected to second ends of the plurality of side plate. In addition a plurality of supporting bar, which is prolonged to support the glasses, are formed on said plurality of side plate. The plurality of side plate, the top plate, the bottom plate and the plurality of supporting bar are made of a metal conductor and a conductive resin to discharge the static electricity formed on the glasses and the cassette.
摘要:
An expandable dish rack contains a drawer-like tray within and in the bottom of the dish rack. Water from dishes on the dish rack drains through frontal slots in the downwardly slanted floor into the tray. If additional dish space is required, the tray is drawn outwards, acting as an extended dish rack and a drainage board. In this position water drains through the same frontal slots and collects in the tray. The floor slots in the dish rack permit water drainage only into the tray whether the tray is in its outward or withdrawn position. The spaced apart ridges on the tray keep dishes above the collected water on the bottom surface of the tray. The tray is removable and the water is expelled therefrom.
