Abstract: The present invention intends to provide a gap-forming sheet for laminating a plurality of flat plate electrodes, for example, for controlling electron beam at high accuracy in a short period of time. Gap-forming sheets each including a support member formed by depolymerizing resin, gap members for providing gaps between the flat plate electrodes, and a bonding paste for bonding the flat plate electrodes, are held between the flat plate electrodes, which are baked to decompose the support members, and thus, by melting the bonding paste, the flat plate electrodes are joined together for lamination, with gaps being provided by the gap members.

Abstract: A method for forming a contact via in an integrated circuit includes the formation of an aluminum conductive element on an integrated circuit device. A conformal insulating layer is then deposited over the device. Using a masking layer, an anisotropic etch is performed to open a via through the conformal insulating layer. During the anisotropic etch, polymers are created from the resist and etch chemistry and adhere to the sidewalls of the via. A resist developer containing tetramethylammonium hydroxide (TMAX) is used to remove the polymers from the via. A contact may now be formed by depositing conductive material into the via.

Abstract: A motor-vehicle latent-heat storage unit is made by first positioning an elongated rectangular sheet-metal blank over a longitudinally extending slot formed in a die and then pressing an elongated anvil bar forming one of a pair of ultrasonic welding tools down against the blank over the slot to push the bar and the blank into the slot. This imparts to the blank a U-section and leaves longitudinally extending edge regions of the blank projecting out of the slot past the anvil bar. These edge regions are then folded transversely one after the other inward over the bar to form the blank into a tube with the edge regions overlapping each other. The other of the ultrasonic welding tools is subsequently pressed against the overlapped edge regions and therethrough against the anvil bar to ultrasonically weld together the overlapped edge regions along a full length of the tube. Finally the welded tube and the bar are moved longitudinally relative to each other to separate the tube from the bar.

Abstract: A method and apparatus for treating refuse by non-combustibly shrinking polyfoam plastics in the refuse. The trash is heated at a temperature between 250.degree. and 500.degree. for a minimum period of time. A rotatable chamber heats the refuse and transports the refuse for the minimum period of time. An operator controls the rate of rotation of the chamber and thus the time of heating in accordance with the moisture content of the refuse. A steam/air mixture used as a heat medium serves to kill bacteria in the refuse in addition to shrinking and drying the refuse.

Abstract: As a rule a melt-good consisting of glass fragments and glass batching will be moist and tend to agglomerate and bridge-form when being preheated in a plate heat-exchanger 10 whereby the travel of the melt-good through the plate heat-exchanger 10 may be blocked. To remedy these drawbacks, the preheating stage is preceded by a drying stage of the moist melt-good. For that purpose, in the intake zone of the melt-good, the moisture of the melt-good is evaporated by means of a separate feed of hot heating gas into the already cooled flows of heating gas. At the same time the heated melt-good is made to pass through cavities 12 through which the steam may escape to the outside. Thereby condensation shall be precluded and only fluid or friable melt-good arrives at the preheating stage.

The pixel elements have first and second ramp elements which are different from one another and facets which are different. The pixel element facets are supported from a hub which has flat outer faces which contact the leaf springs to restrain the pixel element from rotation and a slot extending along its length to permit the hub to be positioned over an axle support. A carriage supports a movable activator bank located rearward of the pixel elements.

Abstract: A fishing lure having an elongate deformable body whereby the depth of the lure and the path traveled by the lure in a body of water, when the lure is pulled through the water, may be adjusted by changing the shape of the deformable lead body. The deformable body has a nonuniform shape which results in the lure being oriented in the water such that the flat top faces the surface of the water. When the fishing lure is pulled through the water, the fishing lure will be at a specific depth depending on the weight of the lure and the speed at which the lure is pulled through the water. When the deformable body of the same lure is bent to form a concave top surface, the change in the hydrodynamics of the lure body causes the lure, when pulled at the same speed, to be positioned closer to the surface of the water. Conversely, when the deformable body of the same lure is bent to form a convex top surface, the change in hydrodynamics causes the lure to be positioned deeper in the water.
