Patent GB-2229035-A (GB)
Title: A method of producing a semiconductor device
Inventor: NAKATANI MITSUNORI
IPC: H01L21/338
Filed: 1989-11-28
Abstract: To form an isolating oxide region (4) in a semiconductor 16 photosensitive resin (3) is deposited on a step portion on a semiconductor substrate, so that it overhangs both ends of the step portion. An insulating film (4) is deposited to a height approximately equal to that of the step portion on the entire surface by CVD at low temperature, thereby producing an insulating film having a discontinuity at the step portion. The insulating film and the photosensitive resin remaining on the step portion are removed by a lift-off method to leave a flattened surface. A similar method (Figs. 2, 3) may be used in the production of a multi layer wiring. <IMAGE>

Title: Drawing device having indexable stylus turret
Inventor: AUER ROBERT T
IPC: B43L1/00
Filed: 1990-04-24
Abstract: A drawing device for producing line drawings on a screen to which powder adheres and having intersecting shiftable transverse and longitudinal rods 19,20 has, supported at the intersection of the rods, an indexable stylus turret and carrier assembly. The carrier 18 is slidably supported on the transverse rod 20 and the stylus turret 17, received therein, is slidably supported on the longitudinal rod 19. The turret 17 is indexable to present to the underside of the screen 13, for scraping powder therefrom to draw a line, any one of three styluses S1-S3 each producing a line of different width or character or to present a blank stylus S4 which interrupts the drawn line. Indexing is effected by pressing an actuator bar 25 operatively coupled to the longitudinal rod 19 carrying the turret 17 to depress this rod and to cause a turret pin I1-I4, to engage an abutment 36 in the carrier, this action causing the turret to index to its next operative position. <IMAGE>

Title: Adaptive vibration control system
Inventor: STOTHERS IAN
IPC: G10K11/178
Filed: 1992-10-21
Abstract: An adaptive control system reducing undesired signals or vibrations comprises a processor 36 which provides secondary signals for sources 37 for interference with the undesired signals. Sensors 42 measure the residual vibration which is indicative of the interference between the undesired and secondary signals. The processor 36 uses the residual signal to adjust the secondary signals to reduce the residual signals. Noise generation means 48 is provided to add a low level noise signal to the secondary signal and to provide a low level noise signal to the processor 36. The processor 36 is adapted to transform the low level noise signal and the residual signal from the sensors 42 to provide the amplitude and phase of spectral components of the signals. The processor 36 modifies the secondary signals using these spectral components to obtain better reduction of the undesired signals.

Title: Double clutch arrangement
Inventor: BARTON JOHN ROBERT
IPC: F16D25/0638
Filed: 1993-03-05
Abstract: A double clutch arrangement (13) includes first and second clutches (21, 22) with an engaging means in the form of a piston (35) positioned between the clutches. The piston is movable in a first direction to engage the first clutch (21) and disengage the second clutch (22) and in a second direction opposite to said first direction to engage the second clutch (22) and disengage the first clutch (21). Resilient means in the form of Belleville springs (46, 48) are positioned between the engaging means and each respective clutch so that all clutch engaging pressure is transmitted from the engaging means to each respective clutch via these springs. The springs ensure that during changes between the engaged states of the clutches sufficient clutch engagement pressure is maintained to ensure that the output torque of the arrangement never falls to zero.

Title: Utilizing inertia to produce motive power
Inventor: DOCHERTY PATRICK WILLIAM
IPC: F03G3/00
Filed: 1993-07-01
Abstract: A device for producing motive force (in the direction of arrow A) comprises a pair of moveable members (12, 14) and a magnetic flux producing arrangement, such as a pair of electromagnetic stators (18, 20), for reciprocating the members (12, 14) in an arc with the members travelling in opposite directions. This arrangement produces an unbalanced centrifugal force having a resultant force passing through the peak of the arc, which resultant force may be utilised to produce linear motion. The resultant force is produced intermittently, being at a minimum when the members are diametrically opposite one another, and at a maximum when the members are in alignment at the peak of the arc. The arc may extend through 180 DEG . The device may be mounted on a vehicle where it may be used for steering or braking. <IMAGE>

Title: Electric storage heater
Inventor: ELLIS GORDON
IPC: F24H9/20
Filed: 1993-08-06
Abstract: An electric storage heater uses one or more containers 7 for a phase change heat storage medium which changes its state at a relatively low temperature, say less than 70 DEG C. Air drawn in towards the lower end of the heater 5 emerges from the upper end 6 after having passed over the surface of the containers containing the phase change material.

Title: Hopper dust containment filler.
Inventor: LETTICE ANDREW
IPC: B65G69/18
Filed: 1993-09-17
Abstract: A dust containment device for controlling emission from a container for particulate material is described. The device comprises at least one opening and a restrictor for the opening. The restrictor is formed from a baffle including a pair of baffle plates 8, 10, a first of which 8 is fixed in position and a second of which 10 is moveable relative the first between a first position in which the two plates cooperate to prevent egress of material from the container via the opening and a second position in which material can pass to the container via the opening. The second plate second plate is moved from the first to the second position as a result of loading thereof with particulate material. The moveable plate is suitably arranged to return to the first, closed, position under the influence of gravity alone after the passage of particulate material through the opening has ceased. The moveable baffle can be an elastic plate or a rigid hinged plate. <IMAGE>
