Patent GB-2363900-A (GB)
Title: Dry etching system for use in semiconductor manufacture
Inventor: SANGO TOSHIAKI
IPC: C23F4/00
Filed: 2001-04-19
Abstract: Dry etching carried out on a single semiconductor wafer 20, which is electrostatically attracted to a static chuck 6 in the presence of a plasma, employs a control system 1 2 3 4 5 which applies a direct current voltage V to the chuck, the magnitude of which is dependent on the place n occupied by a single wafer in a wafer batch and the time T elapsed from the previous dry etching. In a particular embodiment the DC voltage is changed from a standard value V<SB>s</SB> when a lapse time T from a previous dry etching step is longer than a critical lapse time T1 and when a place n occupied by the single semiconductor wafer 20 in a batch is equal or less than a critical place N1, in order to improve the reproducibility of micro-contact holes formed over the wafer 20.
Patent GB-2361760-A (GB)
Title: Pedal mechanism
Inventor: YADDEHIGE SENA
IPC: G05G5/03
Filed: 2001-04-27
Abstract: Pedal mechanism comprises a pedal arm 18, 218 pivoted in a housing 24, 224 and a friction mechanism for producing the force hysteresis in the pedal to ensure desirable pedal 'feel'. Relative angular movement between the pedal 18, 218 and pad 36, 236 when the pedal is depressed causes the point of contact between the pad and piston 28 or button 228 to move relative to the housing. This movement is resisted by friction between the pad and the piston or button, and by resetting springs 30, 32, 230 which have to be compressed to allow the movement to take place. The same spring(s) provided a restoring force to return the pedal to its initial position when it is released. A second embodiment includes a 'kickdown' feature (150, 151 Fig.4) and end stops (121, 123).

Title: Method and arrangement for asynchronous processing of CCTrCH data
Inventor: GEERS STEVEN NICHOLAS
IPC: H04B1/707
Filed: 2001-10-19
Abstract: A method and arrangement for processing of CCTrCH data in a UMTS system, by: receiving CCTrCH data across a plurality of radio frames and timeslots (310); storing the received CCTrCH data (320); and upon receipt of complete data for a CCTrCH, processing the stored CCTrCH data through channel processing asynchronously to the received timeslot structure (360). Preferably, the received CCTrCH data is stored in a single RAM memory in link-list form, whereby each timeslot of received CCTrCH data can be independently accessed in the memory. This method of buffering the different parts of the received CCTrCH data, so that they can be recombined before the TrCH decoding and de-multiplexing, is both memory efficient and spreads out the processing load over time.

Title: Loop impedance meter
Inventor: BATTEN DOUGLAS WILLIAM
IPC: G01R27/18
Filed: 2001-10-24
Abstract: A loop impedance meter for testing an AC supply includes an electronic control circuit for connecting a load resistance R1 between the live and earth terminals of the supply. The value of R1, and the time for which it is connected, are selected so that the RCD protection in the supply is not tripped. Typically, the load resistance in ohms is between one sixth and one times the mains voltage in volts e.g. 100  L   for a 230V supply, and it is connected for less than 100s. Also disclosed is a loop impedance meter that desensitizes the RCD, before a measurement is made, by means of a series of short current pulses, the pulses consecutively increasing in width. In addition, a loop impedance meter is disclosed that applies several measurement pulses, and extrapolates the resulting measurements to give the impedance value at the AC mains frequency.

Title: Monitoring radioactive emissions
Inventor: GUNN RICHARD DONALD
IPC: G02B6/255
Filed: 2001-11-05
Abstract: Monitoring radioactive emissions from an item, particularly alpha and beta emissions, by measuring ionisation caused by the passage of emissions through a medium. Gaseous emitters present in the medium and background radiation are accounted for by measuring and/or taking steps to avoid a fluctuating background count. In one embodiment ionisation is monitored in two sealed chambers 50, 52, by detectors 56 and 66 respectively. One chamber contains an item 54 to be monitored, while the other is used to obtain a measure of the background radiation in the medium (also see figs 3, 5 and 6). Means 60, preferably a fan, is also provided for moving the medium about the chambers. In other embodiments a single chamber is used and the medium is moved about for a time period prior to measurement in order to allow fluctuations in the background radiation count to fall below a threshold (see figs 1 and 2).

Title: Accumulator type fuel injector
Inventor: TANABE KEIKI
IPC: F02M47/02
Filed: 2000-03-31
Abstract: An accumulator type fuel injector, wherein a controller (8) opens a switching valve (5) for switching a fuel injection rate which controls a high-pressure fuel supply from a high-pressure accumulator (3) to a fuel path (10a) on the downstream side of a check valve (32) for a short time between an auxiliary injection and a main injection so as to form a fuel pressure higher than an auxiliary injection pressure and lower than a main injection pressure in the fuel path on the downstream side of the switching valve, whereby, when a stop valve (7) for injection timing control is opened to start the main injection, an injection pressure at the initial stage of the main injection becomes an appropriate pressure which is higher than the auxiliary injection pressure and lower than the main injection pressure provided after the auxiliary injection, and thus a fuel efficiency and exhaust gas characteristics are improved.

Abstract: A safety-enhanced gun 10 (for instance an air gun, pistol, rifle, toy gun), and an associated method of operating such a gun, comprises a motion sensor (40, Fig 3) which may be either integral with the handle part 30 of the gun or a modular addition to the gun, and a light transmitting/flashing device 20 (LED, eg. 43, Fig 3) which is electrically connected to the motion sensor so that it is activated when the motion sensor detects movement (when the gun is picked-up) and whereby the activated light source identifies (possibly by colour coded lights 20) the type of gun (eg. ranging from a toy gun to an authentic firearm). LEDs can also be activated when the gun is armed, cocked or otherwise ready to be fired. The motion of the gun may be detected through the use of an electric circuit (Fig 3) that induces a spring element (44), an oscillating mass (46) and a ring (348) which is adapted to surround the mass (46). The aim of the arrangement is to be able to easily differentiate and identify guns before use and also to alert bystanders as to wether or not a gun which is being used is of any significant danger.
