Abstract: A liquid storage tank having at least a liquid-retaining wall and usually a structural outer wall and including a porous material therebetween. The porous material forms a structural interconnection with the wall or walls to prevent them from peeling apart and is also typi­cally adapted to wick any liquid which comes in contact with it. Further, the storage tank may have sensors associated with the porous material at strategic points for detecting the presence of a leak. A method of making a storage tank for a liquid is provided wherein at least a liquid-retaining wall and usually a structural outer wall is provided or formed. A porous material typically having a barrier layer formed on one surface thereof is applied to a surface of one of the walls by placing the surface opposite the barrier layer thereon. Further, at least one type of liquid sensor may be installed in the porous material at strategic points for detecting the presence of a leak in the storage tank.

Abstract: Radio transceiver having two angle modulators (23,25) for the transmit signal and for the receive signal and two mixers (17,19) in the receive path. In known radio transceivers it is conventional to supply local oscillations having a single frequency to the mixers. It is usual to provide additional componentry such as frequency synthesizers for generating these local oscillations. This adds to the costs and complexity of the radio tranceiver, and the additional componentry are sources of different frequency generation which may create spurious interferences. To solve these problems the radio tranceiver further comprises a second angle modulator (23) for producing a local oscillator signal comprising a carrier wave of a second frequency, the radio transmission signal is applied to the first mixer (17) and the local oscillator signal is applied to the second mixer (19), and a phase shifter (24) being so arranged that the phase of the signal applied to the first angle modulator differs from the phase of the signal applied to the second angle modulator, the modulation characteristics of the angle modulators being so matched and the phase shifter having such a phase delay that substantial rejection is achieved in the second mixer of a modulation component related to the transmit message signal present in the receive path.

Abstract: A load resistor for use in a semiconductor integrated circuit consists of two portions of conductive material, typically strips of either a silicide or a composite polycrystalline silicon layer and silicide layer formed thereon, formed on a semiconductor substrate and separated from each other by a selected distance. An electrically conductive dopant diffusion barrier is formed on the first and second portions of conductive material. A polycrystalline silicon material is then placed on the structure such that one portion of the polycrystalline silicon material is in ohmic contact through the diffusion barrier with the first portion of conductive material and the other portion of the polycrystalline silicon material is in ohmic contact through the diffusion barrier with the second portion of conductive material. Typically the polycrystalline silicon material is placed on an insulation layer formed on the semiconductor substrate in the portion of the substrate between the two portions of conductive material. The diffusion barrier prevents any dopant from the conductive material from diffusing into the polycrystalline silicon material thereby allowing the polycrystalline silicon material to function as a load resistor having a high resistance in the giga-ohms range. Subsequent high temperature processing of the structure does not change the resistance of the polycrystalline silicon because the dopant diffusion barrier prevents any dopant from the underlying conductive material from diffusing into the polycrystalline silicon material.

Abstract: Both a system (1) and method for laser welding the inner surface (20) of a metallic tube (22), which may be a sleeve (19) inside a heat exchanger tube (22) of a nuclear steam generator (23), is disclosed. The system (1) comprises an elongated tubular housing (57) that is insertable within a reinforcing sleeve (19) disposed within a heat exchanger tube (22), a laser unit (11) for generating a beam of light, a fiber optical conduit (10) for conducting light from the laser unit (11) through the interior of the tubular housing (57), a beam deflection assembly (5) including a mirror (71) canted at an angle of 45° that is rotatably mounted on the distal end (59) of the housing (57) and optically connected to the fiber optical cable (10), and a remotely powered rotary drive assembly (5) for rotating the beam deflection assembly (5) to direct laser light around the inner surface (20) of the tube (22) that includes a motion transducer (77, 89) for converting linear to rotary motion. The motion transducer (77, 89) includes a tubular driven member (77) concentrically disposed within said housing (57) and connected to the beam deflection assembly (5), and a tubular drive member (89) concentrically disposed within the driven member (77) and having a spiral groove (93) around its outer diameter that meshes with a follower ball (87) connected to the inner diameter of the driven tube (77), such that the driven member (77) rotates whenever the drive member (89) is slidably pulled along the longitudinal axis of the housing (57). The linear-to-rotational motion transducer (77, 89) obviates the need for miniaturized electrical or pneumatic motors, which in turn allows the outer diameter of the housing (57) of the system (1) to be made small enough to service small-diametered heat exchanger tubes (22).

Abstract: A video camera (B) includes mode selection switches (76, 96, 98) which selectively interconnect a sensor line shift timing generator (78) with one of three signal sources - (i) a conventional raster scan timing signal from a raster scan sync generator (70), (ii) variable speed external timing signals (t i ) from a tachometer (32), and (iii) fixed speed timing signals developed from the horizontal timing signals of the raster scan sync generator (70). In a time delay and integration mode, the sensor line shift timing generator (78) causes the CCD arrays of an image section (22) and storage section (24) to shift pixel values down the CCD arrays at a rate commensurate with the external timing signal (t i ). As a spot of light emanating from a portion of an object (12) moving through an examination region (14) moves along the CCD array (22, 24), a corresponding pixel charge is shifted through the CCD array at the same speed such that the same pixel charge integrates light from the same spot as it moves the entire length of the CCD array. An output register timing generator (80) generates timing signals for output registers (26) such that an output signal is produced that is compatible with EIA-170 television signal standard. In the conventional raster scan mode, the camera works as a conventional video camera. When connected to the variable frequency timing signal (t i ), the video picture scrolls down the TV monitor clocked by the tachometer (32) in proportion to the speed of the conveyor (A). In a calibration mode, the image scrolls down the video screen at a fixed rate.
