Title: Converting multi-bit audio signal to one-bit
Inventor: AKUNE MAKOTO
IPC: H03H17/00
Filed: 1997-03-20
Abstract: A signal processing apparatus converts a multi-bit audio signal having the conventional sampling frequency fs KHz and m quantizing bits (m is an integer) into a one-bit audio signal having the sampling frequency 64 x fs KHz and one quantizing bit. Hence, the apparatus can offer an audio signal in a highly dynamic range. Further, the apparatus separates sub-data added to the multi-bit audio signal in transmission from the multi-bit audio signal and sigma-delta modulates the multi-bit audio signal through the effect of a sigma-delta modulator. This suppresses the adverse effect on the audio signal. The apparatus also controls the supply of a timing signal and a clock signal to the sigma-delta modulator and a D/A converter based on the sub-data. This makes it possible to positively control switching timing. This can be for magneto-optical discs.

Patent GB-2319395-A (GB)
Title: MOS-gated semiconductor device
Inventor: KINZER DANIEL M
IPC: H01L29/10
Filed: 1997-11-18
Abstract: An MOS-gated power semiconductor device such as an IGBT or MOS-gated thyristor is formed by a process that uses a reduced number of masking steps and minimizes the number of critical alignments. A first photolithographic masking step defines the body 30 or channel region and the source region 50,51 of each of the cells. A second photolithographic step is aligned to a small central area above the source region of each of the cells or strips, the only critical alignment in the process, and is used to define openings in a protective oxide layer 61 which, in turn, masks the etching of depressions in the substrate surface and the formation of a contact region. An isotropic etch undercuts the protective oxide to expose shoulders at the silicon surface of the chip which surround the etched holes. A conductive layer 84 fills the holes and thus contacts the underlying body regions and overlaps the shoulders surroundings the source regions at the silicon surface. The conductive layer is sintered at a temperature that is sufficiently high to achieve low contact resistance between the metal and body regions but is low enough to be tolerated by the conductive layer.

Title: Transmitting communications signals over a power line network
Inventor: RICKARD ROBIN PAUL
IPC: H04B3/56
Filed: 1998-03-17
Abstract: Apparatus for transmitting communications signals over a power distribution network comprises a substation having a plurality of powerlines 40-45 leading from it for distributing electricity and a plurality of communications stations coupled thereto. The apparatus includes devices for controlling flow of the communications signals according to the station that it is desired to communicate with by preferentially coupling with a power line to which the desired communications station is coupled. In figure 2, this is done by modifying via control of the weighting W1-W3 applied to one of the split set of signals for controlling the combined power delivered to the lines. In an alternative arrangement (figs.6, 7 not shown), each of the power lines has devices for coupling signals onto the line and the step of controlling flow of the signals comprises selecting which of the coupling devices are used. The selecting can be made by one or more switching devices in the paths leading to the coupling units.

Title: Apparatus for Measuring Particle Dimensions in Fluids
Inventor: SCHWARTZ FREIDEL HERBERT
IPC: G01N15/02
Filed: 1998-06-03
Abstract: Apparatus for analysing dimensions of particles contained in a fluid comprises an optical device (6) incorporating a source of light which can be displaced along a path (eg running around a centre line of the apparatus). An optical system incorporating transparent windows (3,4) is disposed between the source and the fluid, which focuses the light into the fluid along the path (20). A detector device detects the light scattered by the particles and generates an electric signal dependent on the scattered light, feeding an analysis unit for determining the size and/or the size distribution of the particles. The optical system incorporates an interface (12) which is stationary relative to the housing and is displaced non rotationally symmetrical in relation to the centre line of the apparatus which causes the distance between the focal point (20) and the window (12) to vary as the light is displaced, such that for some portion of the path (20) said distance is optimal to maximise the scattered light signal.

Title: A method of friction welding tubular members
Inventor: HUTT GRAHAM ANTHONY
IPC: B29C65/06
Filed: 1997-02-26
Abstract: A method of welding two tubular members (1, 2) in end to end relationship includes providing the end of each tubular member (1, 2) to be joined with a shaped portion (3, 4). The shaped portion (3,4) has a surface (10) which is substantially perpendicular to the radius of the tubular member (1,2) and a second surface (13) at an obtuse angle to the radius of the tubular member (1, 2). Hence, when the ends to be joined are brought into contact with each other, shaped portions (3,4) define a three-sided channel (13,10,13). A ring-shaped member (6) having a quadrilateral cross section is located in the channel. The ring-shaped member (6) has a radius which is greater than the radius of the first surface arid less than the radius of the external wall of the tubular member (1, 2). The ring-shaped member (6) is rotated relative to the tubular members (1, 2) and the ring-shaped member (6) is subsequently compressed to bring the ring-shaped member (6) into contact with the shaped portions (3, 4) of the tubular members (1, 2) to form a friction weld which welds the tubular members (1, 2) together in end to end relationship.

Title: High-speed pouch forming,sealing and filling machine,method of operation and multi-layer film therefor
Inventor: BASQUE ROLAND
IPC: B65B9/20
Filed: 1999-11-16
Abstract: A multi-layer film structure (12) has an inner sealing layer (36) which comprises metallocene resin, a core (38) which includes polypropylene copolymer and an outer layer (37)and a thickness within a range between about 50 and 70 microns (2.0 - 2.75 mil) . By utilizing this thin film with specific properties the sealers (19, 23) may be operated at lower temperatures thereby resulting in an energy saving and they produce seals having improved seal strength of 30% to 50% as compared with known prior mono-layer polyethylene film. The seal initiation temperature is reduced by 10{C to 15{C and the film exhibits an improved machine direction tensile strength of 25% to 40% and an improvement of 30% to 50% in puncture resistance as compared with a 76 microns (3 mil) mono-layer polyethylene film. This results in a reduction in the sealing cycle time and an increase in the throughput of the machine. This results in a liquid pouch having a substantial improvement in drop test performance, puncture resistance and seal strength.

Patent HU-T62518-A (HU)
Title: Automatic clutch controlling device
Inventor: SLICKER JAMES MELVIN
IPC: F16D48/06
Filed: 1992-10-06
Abstract: The system has an engine speed sensor producing a signal corresponding to the rotational speed. A reference speed generator produces a signal based on the speed sensor and the throttle signal, to select either launch or creep values. A transmission input speed sensor is connected to the output shaft of the friction clutch. An actuator controls the engagement/disengagement of the frictional clutch in response to a controller, which utilises the sensor signals. An algebraic summer forms a difference signal between the reference speed and the transmission signal and a compensator causes the clutch to be partially engaged such that the transmission input speed signal asymptotically approaches the reference signal.
