Abstract: The bottom-nozzle plate (46) is of substantially solid configuration with cut-out regions (50) formed therein at locations which are above and in direct align­ment with the coolant inlet holes (52) of the lower core plate (14) when the fuel assembly including the debris-­resistant bottom nozzle is seated thereon. Each cut-out region (50) has thereacross an open criss-cross structure (54) defining a plurality of openings each of which has a cross-sectional dimension such as to filter out coolant­borne debris too large to freely pass through the un­occupied spaces in the fuel assembly's lowermost support grid supporting fuel rods, yet to pass debris small enough to freely pass also through the unoccupied spaces of the lowermost grid.

Abstract: The article (10) is made by a process in which a substrate (12) having an effective edge (16) in a closed pattern on its surface receives a fluent plastic composition which is cast into an elongated area (18) defined by the edge. Relative movement between a casting head and the substrate is effected in a direction generally parallel to the direction of elongation of the area while varying amounts of the fluent plastic composition are cast on portions of the area (18) in relation to the widths of the portions. The fluent plastic flows to the effective edge and is then cured to form a clear plastic cap (14).

Abstract: The invention relates to a digital-analog convert­er (DAC), and is designed to prevent fundamentally "zero cross distortion" in the output voltage waveform of DAC or the generation of glitch and to improve the fidelity considerably when reproducing analog signals of minute level in particular, equipped with two DACs, a first DAC and a second DAC, and when reproducing a since wave for example, the digital-analog converter outputs the waveform corresponding to the input digital signal from the first DAC and outputs a certain refer­ence voltage (0V for example) from the second DAC dur­ing a reproducing period of a positive half-wave. 
     Conversely, during a reproducing period of a nega­tive half-wave, a positive waveform of which the input digital signal from the second DAC is inverted is out­putted and a certain reference voltage (0V for example) is outputted from the first DAC. As a result of this, the output voltage of both DACs becomes positive or 0V so that the output voltage will not cross zero, and it becomes possible to eliminate "zero corss distortion" and the like.

Abstract: A refrigerating system includes a refrigerant circuit having a condensor (201), evaporator (203) and slant plate type compressor (10) with a variable displacement mechanism. Two passages (812,822) communicate between the crank chamber (13) and the suction chamber (141) in the cylinder block (12). A bellows (811) is disposed in a first passage (812) and controls the communication between the crank chamber and the suction chamber in response to crank chamber pressure. A control valve (821) is disposed in the second passage (822) and controls communication between the crank chamber and the suction chamber in the second passage in response to a signal generated outside of the compressor. A control circuit controls the generation of the signal in response to thermodyamic characteristics related to the evaporator (203). The signal activiates or deactivates the second control valve (821) when the charateristic indicates a value beyond a predetermined range of values. This configuration enables the compressor to obtain better cool down characteristics in the passenger compartment of an automobile.

Abstract: A method for passivating the surface of a compound semiconductor (12) comprises annealing the substrate (12) to form an anion rich surface layer containing cationic and anionic oxides and stripping the oxides to leave only a very thin anionic layer on the surface. The substrate (12) is then subjected to an H₂ plasma cleaning to remove chemisorbed oxygen. An N₂ plasma cleaning is then performed to form an anionic nitride layer (20) that is free of any cationic nitride. A layer of insulating material (22), such as, a native or other oxide, or a nitride, is deposited. The resulting structure (10) has a very low interface state density such that the Fermi level may be swept through the entire band gap.

Abstract: An improved method for separating a particular liquid component from a solution containing two or more liquid components having different boiling points. The method employs a vessel divided into a solution chamber and a vacuum chamber by a permeable membrane which is selectively and preferentially permeable to the vapors of the components having a lower boiling point than those of the other components. The solution is placed in the solution chamber out of direct contact with the permeable membrane at which condition a vacuum is applied to the vacuum chamber to evaporate the solution in the chamber and draw the resulting vapors through the permeable membrane into the vacuum chamber, thereby collecting the particular component from the solution in a vapor-to-vapor permeation through the permeable membrane. The improvement is to maintain the solution in the solution chamber at a higher temperature than an environment, and particularly the permeable membrane for increased separation efficiency.

Abstract: Tissue paper having a soft, silky, flannel-like tactile feel through incorporation of an effective amount of a chemical additive such as, for example, a polysiloxane. Preferably, less than about 2% of such a chemical additive on a dry fiber weight basis, is incorporated in the tissue paper: more preferably, only about 0.3% or less is so retained. Tissue paper embodiments of the present invention may further comprise a quantity of surfactant material to enhance softness and/or surface smoothness and/or wettability control; and/or a quantity of a binder material such as starch for linting control. For example, embodiments which would otherwise manifest a significant reduction in wettability due to incorporated chemical additives may further comprise sufficient surfactant to at least partially offset the reduction of wettability induced by the chemical additive: e.g., for toilet tissue embodiments to be sufficiently wettable to be handled in contemporary sewage handling and disposal systems. Additionally, for example, embodiments which would otherwise manifest a significant exacerbation of linting due to such incorporation of chemical additives alone or in combination with surfactant materials, may further comprise an effective amount of a binder such as starch to at least partially offset the linting exacerbation effects of the chemical additive and, if present, surfactant materials.

Abstract: A compatible recording/reproducing apparatus for selective use with a standard-size tape cassette and compact-size tape cassette. Included is a main chassis having a set of fixed positioning pins for positioning the standard-size tape cassette thereon, and a pair of drive spindle for driving engagement with the reel hubs of the standard-size tape cassette. A floating chassis, much less in size than the main chassis, is mounted thereto for displacement in a direction at right angles with the principal plane of the main chassis. The floating chassis has mounted thereon another set of positioning pins for positioning the compact-size tape cassette thereon, and a drive gear for driving engagement with a driven gear incorporated with the compact-size tape cassette. Positioned on the floating chassis, the compact-size tape cassette has its magnetic tape transported by the drive gear and one of the drive spindles on the main chassis.
