Title: Collector for radiation-generated current carriers in a semiconductor structure
Inventor: KIRSCH HOWARD CLAYTON
IPC: H01L21/74
Filed: 1982-12-03
Abstract: An n+ type buried grid layer (16), at the interface of a p+ type semiconductor substrate (12) and a p type epitaxial layer (14), serves to absorb (collect) alpha-particle-induced charge and other stray charge in the epitaxial layer and substrate. The grid layer is spaced sufficiently from a major surface (18) of the epitaxial layer so as not to have any significant adverse effect on circuits and/or devices fabricated on the major surface. Circuits and/or devices fabricated on the major surface of the epitaxial layer are thus at least partly protected against loss of information due to alpha particle hits and other stray leakage generators. When no epitaxial layer is used, the buried grid is formed below the major surface of the substrate into which circuits and/or device are fabricated. <IMAGE>

Title: Apparatus for nucleating a liquid chemical constituent of a reaction injection molding system
Inventor: KHANNA VIMAL K
IPC: B29B7/76
Filed: 1983-07-19
Abstract: The apparatus includes a tank (10) to which the liquid chemical constituent (e.g. a polyol) is supplied. A relatively inert gas is also supplied to the tank to form a gas blanket above the liquid, the pressure of the gas blanket being maintained at a predetermined value. A recirculation circuit (22, 28) circulates liquid chemical constituent from the tank (10) to a controlled outlet (26) and returns any liquid not passed therethrough to the tank (10), the nucleating gas being introduced into the liquid by means of a mixer (32) through which the liquid flows. The mixer (32) introduces the nucleating gas into the liquid in the direction of flow of the liquid (see Fig. 2 for mixer details). To help maintain a predetermined level of nucleation in the liquid, the gas supply (76, 80) may be controlled to supply gas at a rate proportional to the difference in the required density (i.e. nucleation level) and the density of the nucleated liquid as measured by means (66, 68) in a second recirculation circuit (64). <IMAGE>

Title: Load transducer
Inventor: VINCENT REGINALD FREDERICK
IPC: G01L1/22
Filed: 1984-01-19
Abstract: A load transducer comprises a strain-gauged bobbin 11 located between and insulated from two metal diaphragm members 14, 15. Bosses 16, 17 project from the diaphragm members 14, 15 into opposite ends of a bore which extends centrally of the bobbin 11.

Title: Treatment of sodium ferrite-containing particles
Inventor: PREW STANLEY R
IPC: D21C11/00
Filed: 1986-06-06
Abstract: Sodium ferrite-containing particles are charged to one or more hydrolysis cells which preferably revolve about the vertical centre line of a generally cylindrical tank, the tank being radially partitioned into a plurality of liquid-receiving reservoirs sequentially arranged, in order of the direction of revolution of the cells, from a first through one or more intermediate to a last reservoir. Charging of the cells with sodium ferrite-containing particles takes place immediately before the cells pass over the first reservoir and the discharge of particles is effected immediately after the last reservoir is passed. Water is introduced to the cells over the last reservoir and the liquid recovered in the last reservoir is moved to be introduced sequentially to the cells as they are positioned adjacent the intermediate reservoirs. The increasingly enriched sodium hydroxide liquid is recovered in the first reservoir and removed from the system. <IMAGE>
