Title: Electron shower generation.
Inventor: SHONO KAZUHIRO
IPC: H01J37/02
Filed: 1992-03-11
Abstract: An electron shower apparatus 1, for neutralising the charge formed on a semiconductor target 9 during ion implantation, is operated or constructed in such a way that the magnetic field generated by the heating current flowing in the electron emitting filament 2 is reduced or eliminated whereby it's adverse effect on the emitted electron shower 11 is reduced or avoided. This may be achieved by (i) pulsing the filament current using pulse source 6 and extracting the electron shower only during the periods when the filament current is off; (ii) providing an adjacent element either separate from or integral with the filament, Figs 5-9 (not shown), through which current flows in a direction to provide an opposing or cancelling magnetic field; (iii) using a permanent or electromagnet to provide an opposing magnetic field, Fig. 10 (not shown). Two pulsed sources as in (i) may be operated alternately to give an effectively continuous electron shower at the target. The filament may be divided into three separately energised parts which are controlled individually in response to the monitored target charge distribution, Figs 11-13 (not shown), to vary the charge profile or position of the electron shower. Alternatively, Fig. 14 (not shown), a compensating filament may be translated or rotated with respect to the electron cutting filament in response to the monitored target charge. <IMAGE>

Title: Stopper for controlling metal flow from a vessel and delivering gas
Inventor: LEE STEPHEN JOHN
IPC: B22D41/18
Filed: 1992-04-06
Abstract: A monoblock stopper 1 which is adapted to deliver gas during pouring of moulting metal comprising a stopper body having an internal gas chamber 3 and an exit gas port 7, a bore 6 connecting the chamber 3 to the exit port 7 of the stopper, wherein a portion of the bore is formed using a sacrificial void former to provide restricted slit-form path which offers a predetermined resistance to flow to maintain a positive gas pressure within the stopper. The former is preferably tubular having opposed cut-outs so that when the former is consumed on firing the stopper after pressing, two opposed arcuate slit restrictions (9, Fig 3) are formed. Sloping wall 4 about the bore inlet acts to divert debris away from the inlet. <IMAGE>

Patent GB-2267368-A (GB)
Title: Tracking power supplies.
Inventor: DINWIDDIE AARON HAL
IPC: H04N3/185
Filed: 1993-05-20
Abstract: A first voltage regulator (45) energizes a first variable load (32) at a first voltage level (VSTBY) and generates a first control current (I1) which varies with the first variable load. A second voltage regulator (55) energizes a second variable load (52) at a second voltage level (VRUN) and generates a second control current (I2) which varies with the second variable load. First and second control currents (I1, I2) bias a source of reference voltage (e.g. a zener diode 80) which is coupled to each of the voltage regulators; a variation in VSTBY or VRUN changes I1/I2 and VREF, causing one regulator to track a variation in the other. The magnitude of each control current may be related to the difference between the reference voltage and the regulated voltage. One application is in power supplies for CMOS ICs to prevent SCR latching in television apparatus. <IMAGE>

Title: Textured conductor for use in electric cables
Inventor: DOWNIE IAN GRAHAM
IPC: B29C48/154
Filed: 1994-02-22
Abstract: An electric wire or cable having at least one aluminium conductor with extruded insulation with or without a semiconducting extruded screen or screens has the surface of the metallic conductor textured to provide a mechanical interlock with extruded material applied closely to it. This reduces the effect of shrink-back when the wire or cable is cut back for termination or jointing, and may thus allow faster extrusion in manufacture. The textured surface may comprise depressed or raised areas produced by one or more rollers (figure 3) on part or all of the surface. <IMAGE>

IPC: G01L7/08
Filed: 1995-12-22
Abstract: A pressure sensing device comprises a housing 6 having a pressure port 7 to which hydraulic fluid at pressure is applied, and a further port 9 which is e.g. open to the atmosphere. A sensing diaphragm 5 is mounted by its edges within a chamber in the housing 6 so that its opposite sides face the pressure port 7 and the further port 9 respectively.
