Abstract: An improved power semiconductor device and manufacturing method are described wherein the external, thermally conducting, heat transfer face (68a) of the device (94) is electrically insulated by a glassy dielectric (68) which is intimately bonded directly to the conductive heat spreader (61) supporting the semiconductor die (84). By forming the exposed corners of the heat spreader (61) to be substantially smooth curved surfaces (61 d) having a predetermined minimum radius of curvature (61e) greater than the thickness (67) of the glassy dielectric (68), formation of a ridge of glass at the corners (80) and edges (61c) of the heat spreader is avoided. For ease of assembly the piece parts (82) are initially substantially flat and parallel. A molding compound (90) of controlled shrinkage is used to avoid distorting the substantially flat smooth insulated heat transfer face (68a) which remains exposed in the encapsulated device (94).

Abstract: For paint spraying booths where water is circulated from a subsurface reservoir (12) into the booth for removal of airborne sludge particles, apparatus is provided for drawing sludge-laden water from the reservoir and filtering sludge from the water. Sludge-laden water is drawn from the reservoir through a suction head (24) maintained just below the surface of the water in the reservoir and pumped by a submerged pump (22) through an influent conduit (26) to the upper end of a filtration tank (18). The filtration tank is supported above the surface and has an open upper end (28), a lower outlet opening (32) and a filter element or bag (20) supported within the tank with freeboard space along its sides and bottom. 
     The influent conduit (26) has a downwardly extending spout (29) with a stream splitter (38) below the spout to disperse the stream at a narrow angle to the sides of the filter bag. The flow pattern in the filter bag created by the stream splitter results in an uneven distribution of sludge at the bottom of the bag assuring relatively sludge free regions at the bottom of the bag through which water filters readily. The filter bag, preferably formed of burlap weighing between about 6 and about 9 ounces per square foot, removes both large and small sludge particles while maintaining an adequate filtering rate for an extended period of time. When the filter bag is spent, the spout (29) is swung away from the open upper end of the tank allowing the filter bag to be removed and replaced. 
     The pump (22) is run at near maximum efficiency by maintaining its upwardly facing suction head (24) a predetermined distance below the surface of the water. The pump is mounted in a lift (48) for shifting between a lower position during a paint spraying phase of operations and an upper position during a filtering phase. A desired water level in the reservoir (12) is maintained during each phase of operations by a water inlet means having a valve which is opened to add water to the reservoir as needed.

Abstract: An apparatus for measuring the speed of a projectile fired from a handgun or small arm has a measuring path, over which the projectile passes, with light gates disposed spaced apart from one another. Each light gate has a light responsive element, which is shielded from the projectile path by a screen containing a light admitting aperture. An electronic signal evaluation circuit processes the signals emitted by the two light responsive elements in accordance with the darkening of the apertures caused by the projectile in flight above them and supplies these signals to a display device. In order to reduce to a minimum the danger of damage to the apparatus or of harm to persons, caused either by the projectile itself or by parts broken off the apparatus by the projectile without providing a connection between the barrel of the gun and the measuring apparatus, the arrangement is selected such that the two light responsive elements are disposed behind a separating wall common to both. The separating wall includes the light admitting apertures and acts as a screen. It is aligned substantially parallel to the projectile path and extends from near the muzzle of the weapon to beyond the second light responsive element, that is, the one disposed most remotely from the muzzle, and this separating wall protects the light responsive elements from the projectile.

Abstract: A hybrid fiber glass cellulosic blowing insulation. Fiber glass nodules are blended with cellulosic fibers which have been treated with a flame retardant in proportions ranging from 30 to 70% fiber glass and from 70 to 30% treated cellulosic fibers. Some examples of the hybrid insulation are more effective at insulating and, hence, less costly per square foot to install, than either of their component parts. Further, the insulation of the present invention will not smoulder when exposed to a temperature exceeding 500°F (260°C) for a period of six (6) or more hours.

Abstract: A semiconductor substrate (1) has an insultion layer (2, 9) on its surface with a semiconductor layer (6) on the insulation layer (2, 9). The semiconductor layer (6) contacts the substrate (1) through a hole (3) in the insulation layer (2, 9). A conductive region containing a conductive layer 10 of semiconductor material is provided in the insulation layer (2, 9). The conductive layer is separated by insulation (11) from the semiconductor layer (6) and by insulation (9) from the substrate (1). The surface of the insulation (11) is substantially level with the surface of the insulation layer (2) as this prevents the formation of defects in the semiconductor layer (6) adjacent the conductive region, which defects would otherwise reduce the carrier mobility and increase the leakage current. The device may include additional semiconductor and insulator layers, with additional conductive regions, so that a stacked structure may be formed.
