Title: Improvements in land fill contaminant barrier construction
Inventor: MORRICE ANTHONY RONALD SEATON
IPC: E02D19/18
Filed: 1992-11-13
Abstract: Methods of contaminant barrier construction are described in which the trench is excavated in sections, lined with a prefabricated Bentonite barrier sheet and infilled at least in some sections, with a venting material providing a "preferential path" for gaseous contaminants. To support the trench a system of vertical sheet piling 11 is employed in combination with horizontal bracing frames 14 which are designed to be moved vertically in the trench whilst under load. The bracing frames do not obstruct the placing of the contaminant barrier. The frames are raised either before the barrier is set in position or while the trench is being refilled. The invention also defines apparatus for use in the method comprising a bracing frame 4 incorporating cross-struts 24 with substantially arcuate ends which enables the frame to be moved vertically whilst maintaining the trench at constant width. <IMAGE>

Title: Manufacturing method for composite semiconductor devices
Inventor: PATEL NALIN KUMAR
IPC: H01L25/18
Filed: 1993-02-05
Abstract: A semiconductor chip 3 is bonded to another body 5. The chip 3 is formed on a substrate 29 with a sacrificial layer 31 therebetween. A bonding agent 37, 39 is applied to at least one of the chip 3 and the body 5. The chip 3 and body 5 are then brought together and bonded together. Finally, the sacrificial layer 31 is etched away and the substrate 29 removed. The bonding agent 37, 39 may comprise palladium layers which diffuse into the body 5. The method may be used to make a FET or an HEMT when the body 5 is another semiconductor chips. The palladium layers form back gates and, after separation from the substrate 29, front gate electrodes are applied to the top surface of chip 3. <IMAGE>

Title: Electric maze learning device or game apparatus and printed circuit switch      and method of fabricating same
Inventor: WATKINS BOYD GORDON
IPC: G09B23/18
Filed: 1993-04-27
Abstract: A printed circuit board switch and a method for producing it are shown. The switch includes a conductive plug of a first diameter, and a printed circuit board. The printed circuit board defines a first hole A of substantially the first diameter, a pair of half circles B of a substantially smaller second diameter on opposite sides of the first hole extending outward and away from the centre of the first hole, and first and second conductive switch poles 4, 5 on at least one side of the board on opposite sides of the first hole and extending into and along opposite sides of the sides of the first hole. With this switch configuration, closure of the first and second conductive switch poles is effected when the conductive plug is inserted into the first hole. The switch may be produced by drilling holes A + B in the printed circuit board depositing conductive material on the sides of the holes and selectively removing the material therefrom to isolate the holes into 2 parts. A banana jack 6 may then be inserted in the hole to complete the circuit. The printed circuit board may be used as pan of an electric maze learning device or game. <IMAGE>

Title: Tamper evident bag
Inventor: STANGER JOHN ANTHONY
IPC: B65D33/16
Filed: 1993-05-27
Abstract: A security bag 11 is formed by superimposing layers of plastics materials and welding the edges leaving an opening and partially adhering an adhesive tamper evident tape 15 to the bag in such a position as to be able to close the bag. A cover strip 15c is provided to prevent adhesion of the rest of the tape prior to closure of the bag. The bag may be a simple pouch as shown or the opening may be a slit (14a, Figure 4) or have overlapping flaps (Figures 5 and 6). The bag may be formed by longitudinally folding a web of plastics material, forming transverse seals in the folded web by welding, applying the tamper evident tape partially covered by the cover strip and severing the formed bags from the web (Figure 7). The width of the welded seams may be from 1mm to 15mm; for a bag measuring 220mm by 350mm the seam is preferably around 8mm. <IMAGE>

Title: Pulse Welding
Inventor: TABATA YOICHIRO
IPC: B23K9/09
Filed: 1993-11-09
Abstract: The welding current is formed by superimposing a pulse current on a continuous base current. A separation detector 12b provides a separation signal when a molten droplet separates from the tip of a wire electrode. An integrator 12p1 measures the amount of charge of the pulse current from a point in time coincident with the separation signal, and a comparator 12p3 cuts off the pulse current when the measured charge amount is equal to a predetermined value. The current pulses may be arranged in groups, (Fig 47), each group causing separation of one droplet and being terminated by the comparator 12p3. In a short circuiting arc welder, the separation detector is part of a short-circuit/arc decision circuit (12b), (Fig 48A). <IMAGE>

Title: Method and apparatus for the measurement of the mass flowrates of fluid components in a multiphase slug flow
Inventor: WATT JOHN STANLEY
IPC: G01F1/712
Filed: 1993-05-20
Abstract: A dual energy gamma-ray transmission gauge (10) includes radioisotope sources (11) for emitting gamma-rays (13) of two different energies. Gauge (10) also includes a gamma-ray detector which produces signals as a response to the detected gamma-rays. A single energy gamma-ray transmission (17) is disposed upstream of gauge (10) for providing further signals indicative of the respectively detected gamma-rays. These signals are subsequently directed to a processing computer (16) together with signals indicative of the pressure and temperature of the flow obtained from two sensor means (18, 19). The intensities of the gamma-rays are recorded and thereafter a value indicative of the mass flow rates of oil, water and gas can be calculated. The mass flow rates of liquid phases are calculated at substantially all times, however, the phase fractions of oil and water are determined only when a slug is passing gauge (10) in order to maximise the path length of the liquid phase through which the gamma-rays pass. <IMAGE>

Title: Diesel engine fuel cut-off control system
Inventor: NISSAN MOTOR COMPANY LIMITED
IPC: F02M41/12
Filed: 1995-10-13
Abstract: For controlling a diesel engine having a fuel cut valve 29 in a supply line to a fuel injection pump, a dual-CPU type system is used which comprises a main-CPU 51 for controlling the quantity of fuel injected by the pump in accordance with an operation condition of the engine and a sub-CPU 52 for controlling the valve 29. The sub-CPU has a plurality of output ports P1 -P3. A first circuit of the Sub-CPU issues a request for stopping fuel supply to the pump when at least the fuel injection quantity control carried out by the main-CPU is found to be abnormal. A second circuit of the sub-CPU feeds each of the output ports P1 -P with an instruction signal representing present/absence of the request. A logic circuit 54, 55 which is operatively interposed between the output ports of the sub-CPU and the valve 29 operates the valve 29 in a manner to stop the fuel supply to the pump only when all of the instruction signals from the output ports P1 -P3 represent presence of the request. Fuel supply can also be cut off when the engine key is switched to the off position or when the sub-CPU diagnoses any abnormal condition of the engine. Unnecessary engine shut downs, eg when the sub-CPU malfunctions, are avoided. <IMAGE>

Title: Optical disc having variable spare area rate
Inventor: YEO WOON-SEONG
IPC: G11B20/18
Filed: 1998-05-19
Abstract: In a method for setting variable areas of an optical disc which variably sets spare area rates of a prescribed quantity provided for preparing a liably-occurring recording error due to a defect of the optical disc and in the optical disc having the variable spare areas, the total quantity of the spare areas installed to the optical disc may be the same as the prescribed quantity. Also, the size rates of the spare areas are variably set in the radius direction by centering about an intermediate portion of the optical disc. Particularly, the more spare area rates are given to the inner circumferential portion and outer circumferential portion, and the less spare area rates are given to the intermediate portion which is relatively stable portion, thereby minimizing the defect occurring rate to decrease the number of defective discs.
