Title: Fuel control system
Inventor: SMITH TREVOR STANLEY
IPC: G05D16/20
Filed: 1992-06-08
Abstract: In a fuel control system for a gas turbine of an aero-engine, a pressure raising and shut off valve 15 is operated by a piston and cylinder arrangement. A shut off motor-operated pilot valve 120 controls the fuel pressure in a control line 137 of a rapid shut down valve 21 which is operable to connect the cylinder of the valve 15 to a high pressure fuel supply (HPf) via relatively large diameter pipes and so augment the closing force of a spring 27 which acts on the piston 26 of the valve 15. The valve 120 may be operated in response to engine overspeed to close an orifice 142 and thus pressurize the control line 137. Normal shutdown of the valve 15 is effected by closing a second orifice 163 of the valve 120 to pressurize a small bore pipe 165 which connects with the cylinder of the valve 15 and thus provide for a slower closing action. <IMAGE>

Title: A method of manufacturing an article, a method of diffusion bonding and a vacuum chamber
Inventor: DOUGLAS JOSEPH
IPC: B21D26/055
Filed: 1992-07-20
Abstract: A stack (48) of titanium sheets (50, 52, 54) are placed between a pair of pressurisable chambers (24, 34) in a vacuum chamber (10). One of the mating surfaces of each pair of mating surfaces has had a stop off material applied in a desired pattern to prevent diffusion bonding. A pump (14) evacuates the vacuum chamber (10) and heaters (46) heat the stack (48) to evaporate volatile binders from the stop off. When all the binder has been removed the stack is heated and the pressure in the pressurisable chambers (24, 34) is increased to cause a pair of resilient members (22, 32) to apply pressure on the stack (48) to diffusion bond the sheets together. The volatile binder is removed quickly and oxidation of the titanium is prevented during baking out of the binder. The integral structure is then heated and internally pressurised to superplastically form one of the sheets to produce an article of predetermined shape. No welding of the sheets before bonding is required. <IMAGE>

Title: Steering control method for vehicle with power steering and a controllable differential
Inventor: MATSUNO KOUJI
IPC: B62D5/04
Filed: 1992-08-24
Abstract: The vehicle has electric power steering 8, 9, 10 and a hydraulic controller 18 for differential 3 between the driven front wheels 4, 5. When the differential is locked, the quantity and direction of a torque displacement are calculated. If this direction is from the outside wheel (5) to the inside wheel (4), the differential restricting torque is set at zero. If this direction is from inside to outside the ratio between the load displacement magnitudes of the front axle is calculated and the front axle driving torque is calculated from a transmission gear position, an engine speed and a throttle opening degree. The restricting torque is then calculated so that the torque distribution to the inside and outside wheels is equal to the load distribution to them. The correction amount for the steering assist force is calculated from the restricting torque and vehicle characteristics eg. the mass offset of a wheel tire, the diameter of the wheel tire and a steering gear ratio. The hydraulic differential controller (18) is driven on the basis of the calculated restricting torque and the steering correction controller (19) is driven on the basis of the calculated assist force correction amount. Traction is improved and fluctuation of steering assistance is reduced without the need for a viscous coupling. <IMAGE>

Title: Method of igniting a fuel-gas/heating-oxygen mixture
Inventor: KLISCH JOACHIM
IPC: B23K7/10
Filed: 1993-07-13
Abstract: The invention relates to a method of igniting a fuel-gas/heating-oxygen mixture of a thermal processing tool, in particular of a cutting torch, with an ignition flame. In order to reduce the noise emission during ignition, the fuel-gas/heating-oxygen mixture has a smaller proportion of fuel gas relative to a neutral setting. The ignition gas is formed inside the processing tool from a branched-off partial quantity of the lean mixture and is ignited with an ignition device (26) Fig 2 (not shown). When the ignition flame has emerged from the nozzle (33) of the tool, the lean mixture flowing in the vicinity is ignited and the quantity of fuel gas required for the normal setting is then fed to the fuel-gas/heating-oxygen mixture. This method significantly reduces the noise caused during ignition. <IMAGE>

Title: Demodulation devices avoiding pseudo synchronization
Inventor: GOTOH YUICHI
IPC: H04L27/227
Filed: 1996-03-22
Abstract: In a demodulation device for demodulating a phase or quadrature amplitude modulated wave, a baseband signal producing circuit 11p, 11q, 12p, 12q produces a baseband signal having particular information i.e. related to frame sync or error correction code which is dependent on the modulated wave. Responsive to the baseband signal, a phase information producing circuit 14 produces a phase difference signal. A reception logic circuit 41 detects the baseband signal to produce an alarm signal indicative of false locking when the particular information is not detected from the baseband signal. In response to the alarm signal, a reset signal producing circuit 42 produces a reset signal. By reference to the presence and absence of the reset signal, a selector 43 selects, as a control signal, one of the phase difference signal and a cancelling signal which is supplied to the selector. In accordance with the control signal, a wave producing circuit 16, 17 produces a reproduced and a phase-shifted carrier wave which are used to make the baseband signal producing circuit produce the baseband signal.

Title: Inverse discrete cosine transform processor for VLSI implementation
Inventor: PINEDA JUAN
IPC: H04N7/30
Filed: 1996-08-22
Abstract: A fast and efficient implementation of the inverse discrete cosine transform (IDCT). The disclosed IDCT processor achieves a good balance between efficient VLSI implementation and number of needed arithmetic operations and is thus particularly useful in real-time speech and video decompression applications. A standard IDCT computation is modified by factoring an IDCT formula into two parts: a prescaling of each input value followed by a multiplication with a matrix specially chosen so that the product will represent the IDCT of the input data. The premultiply constants are chosen so that the specially chosen matrix has a limited number of distinct values. The VLSI implementation of the matrix multiplication is thus greatly simplified.

Title: Rorming wiring layers in semiconductor devices.
Inventor: ISHIGAMI TAKASHI
IPC: H01L23/532
Filed: 1997-09-26
Abstract: A semiconductor device is provided in which the lower wiring layer 10B-2a has a multi-layered structure, and a titanium nitride film 9-3A is formed to have a portion extending beyond an outer surface of an aluminum alloy film 9-2a. Since a space defined around the width-reduced aluminum alloy film 9-2a and below the extended portion of the titanium nitride film 9-3A is filled with the interlayer insulating film 11, the aluminum alloy film 9-2a is not exposed to the contact hole in which a conductive plug 13 is formed. As a result, the aluminum alloy film 9-2a is kept away from being eroded by CVD carried out for the formation of the plug 13. An upper wiring layer 15 makes contact with the plug 13.
