Title: Determining interpolation weighting coefficients for low ratio sampling rate converter
Inventor: LUTHRA AJAY K
IPC: H04N7/26
Filed: 1990-07-11
Abstract: A technique for reducing the number of coefficients in a low ratio sampling rate converter divides each input sampling rate interval S1-S2 into a plurality of bins i.e. smaller intervals. For each bin a set of conversion coefficients is computed. So long as output data samples lie within the same bin, the same set of coefficients is applied. When the output data samples move to another bin, the set of coefficients applied is changed. Thus a finite set of coefficients are computed rather than computing an exact set for each output data sample. Conversions between PAL and NTSC colour subcarrier sampling rates are described. <IMAGE>

Title: Sterilising chambers with magnetically driven fans
Inventor: SEAGARS TREVOR ANTHONY
IPC: A61L2/26
Filed: 1990-12-06
Abstract: A steriliser, comprising a chamber 8 in which sterilisation occurs, has a fan 14 positioned within the chamber and mounted on one end of a spindle 26. A magnet 28 is mounted on the other end of the spindle and is rotatably mounted to a wall of the chamber. A second magnet 32 is positioned adjacent to the first magnet 28 on the outer side of the chamber wall. A motor 36 or the like imparts rotary motion to the second magnet 32. This causes the magnet 28 within the chamber 8, and hence the fan 14, to rotate. There is consequently no opening through the chamber wall through which contamination may penetrate the chamber. <IMAGE>

Title: Method and apparatus for controllably laser processing a surface
Inventor: MORGAN PETER CHARLES
IPC: B23K26/42
Filed: 1991-02-27
Abstract: Laser treatment of an e.g. metallic surface (1) such as welding or cutting, is carried out by impinging a process beam (2) of laser radiation on the surface (1). A monitoring laser beam (4) of the same wavelength but lower intensity is impinged on the surface prior to the process beam impingement. The change in temperature of the surface (1) resulting from the monitoring beam impingement is measured by means (12) to determine the effective absorption coefficient dependent upon the condition, composition and/or microstructure of the surface (1). At least one operating characteristic of the process beam (2) is varied in dependence upon the measured effective absorption coefficient in order to deliver a constant heat input to the surface along the line of the cut or weld. The beam intensity or the speed of traverse may be varied. <IMAGE>

Patent GB-2243952-A (GB)
Title: Power transistor device having deep increased concentration region
Inventor: MERRILL PERRY
IPC: H01L21/331
Filed: 1991-05-09
Abstract: A cellular insulated gate bipolar transistor ("IGBT") device employs increased concentration in the active region (60, 61, 62) between spaced base (80, 81, 82) to a depth greater than the depth of the base regions. The ion implant dose which is the source of the increased concentration is about 3.5 x 10<12> atoms per centimeter squared and is diffused for about 10 hours at 1175 DEG C. Carrier lifetime is reduced by an increased radiation dose to reduce switching loss without reducing breakdown voltage or increasing forward voltage drop above previous levels. The increased concentration region (60, 61, 62) permits a reduction in the spacing between bases (80, 81, 82) and provides a region of low localized bipolar gain, increasing the device latch current. The avalanche energy which the device can successfully absorb while turning off an inductive load is significantly increased. The very deep increased conduction region is formed before the body and source regions in a process for making the new junction pattern. <IMAGE>

Title: A chemical cartridge for a gas mask or the like
Inventor: HAERTLE KLAUS
IPC: A62B7/08
Filed: 1992-09-24
Abstract: A chemical cartridge 1 for a gas mask or similar breathing equipment, which contains a chemical, e.g. potassium peroxide, which gives off oxygen when acted upon by carbon dioxide and moisture from exhaled air conveyed through it.

Title: Engine exhaust apparatus
Inventor: YAMAKI YASUHITO
IPC: F01N1/24
Filed: 1994-01-05
Abstract: An engine exhaust apparatus comprises a sound suppressing section eg. expansion chambers (6, 7, 8), for lowering the exhaust noise level as an exhaust gas discharged from the exhaust port passes through it; an ejector section (5) for introducing secondary air into the exhaust gas delivered from the sound suppressing section and mixing the gases; and a post-treatment section, eg catalyst (21), for purifying the gas mixture delivered from the ejector section. The exhaust gas discharged from an exhaust manifold gets into the ejector section through the sound suppressing section, and is then purified in the post-treatment section. Therefore, the ejector effect cannot be reduced by the sound suppressing section which is subject to high flow resistance. Thus, the exhaust noise level can be lowered with the ejector effect of the introduction of the secondary air improved considerably, and low cost and simple construction can be enjoyed. <IMAGE>
