Abstract: An orientation layer for a liquid crystal display device is formed from a mixture of at least one reactive liquid-crystalline material and at least one non-reactive liquid-crystalline material. The mixture is brought into contact with a surface of a mould having an orienting effect, as a result of which the molecules in the mixture are oriented. Subsequently, the reactive liquid-crystalline material is made to cure, thereby forming an oriented polymer network in which the non-reactive liquid-crystalline material is dispersed. The orientation layer thus manufactured is very suitable for use in an active display device.

Abstract: A control circuit for a switched reluctance motor is provided with a connection between a second end (208;210) of each stator winding (A,B) and a first end (202;204) of an associated other winding, thereby to permit the flow of current from a phase winding (A) to an energy storage (216) device following the disconnection of the phase winding (A) from a primary power source. The inductive characteristic resists the immediate cessation of current flow following the opening of an associated switch (SA), that continued current flow passes to a capacitor (C₂), increasing voltage potential at the first end (204) of the other stator winding (B) and assisting the initiation of current flow through that stator winding (B).

Abstract: A driver circuit for an electroluminescent display device has first and second clock pulse generator circuits (1,2). The first and second clock pulses are applied to a gate circuit (3) to allow the first clock pulse to pass when both the first and second clock pulses are a high level. From the output of the gate circuit, a combination of a transistor (41) and an inductance (42) generate a high voltage pulse. The high voltage pulse is rectified in a triple voltage rectifying circuit (43) to output a high voltage output for driving the display device such as EL elements, and the high voltage output can be reset by a low frequency pulse output from a discharge circuit (50). As a result, no inverter is required, and a small-sixed and light-weight driver circuit is achieved with a long luminescence life of the EL elements and without noises offensive to the ear.

Abstract: A method of operating on a workpiece comprises offering a probe (24) of material harder than the workpiece material to a continuous or substantially continuous surface of the workpiece, the probe depending from a containment member having a surface which faces the workpiece. Relative cyclic movement is caused between the probe (24) and the workpiece while urging the probe and workpiece together whereby frictional heat is generated as the probe enters the workpiece so as to create a plasticised region in the workpiece material around the probe, the containment member substantially preventing dispersal of the plasticised material. The cyclic movement is stopped and the plasticised material allowed to solidify around the probe.

Abstract: A programmable reference used to identify a state of an array cell in a multi-density or low voltage supply flash EEPROM memory array. The programmable reference includes one or more reference cells, each reference cell having a floating gate which is programmed to control its threshold value. The array cells are read by applying an identical voltage to the gate of the array cell and the reference cell and comparing outputs to determine the array cell state. During read of an array cell, the programmable reference cell is biased the same as the array cell, so that the difference in threshold values between reference cells and array cells remain constant with a change in V cc . Circuitry is included for programming the reference cells utilizing a simple resistor ratio. Programming is performed at test time, preferably by the manufacturer, to assure V cc  remains within strict tolerances. The array cells are programmed and read without resistor biasing and under looser tolerances using the reference cells at a later time.
