Title: A boot for fitting about a longitudinally extending member
Inventor: DUPONT ANDRE
IPC: H02G15/18
Filed: 2000-03-09
Abstract: A boot for fitting about a longitudinally extending member (34) such as a cable, the boot made from a resilient sheet (2) of material having opposing side edges (4, 6) and an unstretched width that is insufficient for the side edges (4, 6) to abut when the sheet (2) is wrapped around a connection zone of the longitudinally extending member (34). A stretching means (30) is removably fittable to the resilient sheet (2) which results in the resilient sheet having a stretched width that is sufficient for the side edges (4, 6) to abut when the sheet (2) is wrapped around the connection zone. A clasp (38) grips the resilient sheet (2) along the side edges (4, 6) whereby a tubular shape is maintained. The stretching means (30) may comprise plate members which are insertable into cavities in the resilient sheet (2) and removable therefrom by pulling members (40) to permit the resilient sheet (2) to resiliently contract onto the connection zone.

Title: Method and apparatus for rinsing an object which has been cleaned with an acidic or alkaline cleaning chemical
Inventor: KAWAGUCHI HIDEHIKO
IPC: B08B3/08
Filed: 2000-03-21
Abstract: A method and an apparatus for rinsing a cleaned object (W) capable of permitting a cleaning chemical liquid adhered to the object (W) to be substantially fully removed therefrom while substantially reducing the amount of pure water used for rinsing. The object (W) cleaned with a cleaning chemical liquid (11) having acidity or alkalinity in a cleaning chemical liquid bath (12) is immersed in a rinse bath (22) filled with pure water (21), so that the cleaning chemical liquid adhered to the object (W) may be rinsed off therefrom while pure water is continuously fed to the rinse bath (22). A neutralizing chemical liquid (26) of alkalinity or acidity opposite to that of the cleaning chemical liquid (11) is added to the pure water (21) in the rinse bath (22) by feeding the liquid (26) from a neutralizing chemical liquid tank (25) using a neutralizing chemical liquid feed pump (28) and a pump controller (27). Thus, the cleaning chemical liquid introduced into the rinse tank (22) while being adhered to the object (W) is neutralized by the neutralizing chemical liquid, to thereby be converted into a salt readily soluble in pure water, which salt is then outwardly discharged together with the pure water overflowing the rinse bath (22). The object (W) may be a semiconductor wafer or a glass element for an LCD.

Title: Power reduction in an associative cache memory
Inventor: CHOI HOON
IPC: G06F12/08
Filed: 2001-03-13
Abstract: A cache memory having K ways and N sets which requires less power to function comprises a plurality of cache memory units 502-508 and a unit selection means 510. The unit selection means uses bits contained within a formatted memory address (Fig 6) to activate a cache unit at a given time. Each cache memory unit comprises a tag array 560 and data array 580 constructed of N sets wherein each set has K ways and is connected to match lines. On activation of the unit a set selection decoder 530 determines the correct set to use and enables a way selection decoder 540, The way selection decoder then generates way selection signals to select the K ways in response to an externally provided mode signal and a way selection signal. The tag array is adapted to compare tag addresses held in the K ways with an external tag address and when the two are identical activate a match line to indicate a cache hit. Preferably the mode signal will be either a read or write indicator.

Patent GB-2376572-A (GB)
Title: Flux impulse motor
Inventor: HOBBY ROGER BARRY
IPC: H02K19/10
Filed: 2001-06-11
Abstract: A motor 1 has a stator 2 and a rotor 10 with at least two salient poles (10 a, b). The stator 2 has a commutating salient pole 11 with a winding 7, and a field-producing salient pole 12 with a winding 8. An outer back-iron 13 magnetically joins the bases of the stator poles. An inner back-iron 14 extends from the field pole 12 around the rotor to an extent that a substantial amount of the magnetic field between the poles of the rotor is short-circuited by the inner back-iron, at least for a part of its rotation. In one embodiment, the rotor 10 is magnetised and an electrical circuit produces an alternating magnetic field in the commuting pole 11 to attract each rotor pole as it approaches the commutating pole, and to repel it as it moves away. In an alternative embodiment, the rotor is not magnetised and a permanent magnetisation is provided in the inner back-iron. In this case, the electrical circuit produces a switched magnetic field which attracts one rotor pole until a minimum reluctance is achieved. The field is then de-energised until the other pole approaches the commutating pole of the stator.

Title: Self-drive apparatus that converts rotary motion into linear motion of the apparatus
Inventor: KRAWIECKI JAN RYSZARD
IPC: F03G3/00
Filed: 2002-01-11
Abstract: The self-drive apparatus (fig 1) has rotating assembly drive discs (7, figs 7 and 8) that are rotated by a motor (10, fig 7). The rotation of the drive discs cause linear reciprocating motion of masses (m1-3, fig 6), the masses are also rotated by motors (17, fig 9). The masses have rotating spheres (19, fig 10) located on the guide surface (15, fig 10). The combination of the linear reciprocating motion and the centrifugal force generated by the rotating spheres enables constant contact of the pistons (14, fig 10) with the drive discs and produces a directional impulse (fig 19) that results in linear motion of the self-drive apparatus.

Abstract: Method of estimating the number of mobile terminals 5A-5J with a particular profile within a cell 1 or any other region. Also, a method of selecting on the basis of this estimate, a scheme of communication with those terminals. The selection may be between a simultaneous broadcast and selective downlinking to individual mobile terminals, the determining factor being a threshold of number of mobile terminals within the region. Method of estimating includes broadcasting a request for only mobiles with required profile to respond. Another criteria may be necessary for response e.g. a digit of the IMSI number or a random number generated in the terminal thereby getting only a sampled response. Other methods of estimation in CDMA systems include, measuring noise or interference levels after sending request for a response.
