A semiconductor device including a semiconductive body having formed therein an active region and a termination feature which includes spaced field rings disposed around the active region and diffusion rings of the same conductivity type as, but different conductivity than the semiconductive body formed between each pair of field rings.

An alternating pressure pad comprises at least two sets of inflatable cells, an air supply line to each set, a pump to circulate pressurized air through a circuit including the sets of cells and to return air from the cells to the pump, valve means for alternately causing inflation and deflation of each set, a sensor pad in the circuit through which pressurized air is passed and detecting means for detecting a reduction in air flow through the sensor pad to a level below a predetermined level an...

A printhead assembly for an ink jet printer has an elongate support structure (1) with alternating segments of different materials (3, 4). The segments are bonded end to end. The materials may have different coefficients of thermal expansion. The support member materials (3, 4) are selected and structurally configured so that the effective coefficient of thermal expansion of the support member as a whole substantially matches that of a printhead substrate material.

A circuit is described for producing an alternating voltage in an electronic device which is remotely fed over a digital transmission path. By the pulses of a clock (8) two capacitors, C1, C2 are charged via a transistor (T1) and a transformer (10), one of them (C2) being discharged over a parallel resistor (R2). A coupling capacitor (CK) which is charged by the other capacitor (C1) is discharged alternately by the influence of the dischargeable capacitor (C2) over a transistor (T2).

An alternating electrical generator which is adapted to reduce/eliminate "Iron losses" and the associated problems of overheating of the windings comprises a rotor; a plurality of pole sections spaced around the circumference of a rotor core member at a constant pole section pitch; a toothed stator; two or more independent windings; and, a plurality of bridge members to separate adjacent windings. The bridge members have a length equal to an even number of pole section lengths, to ensure that an...

An alternating-current electrical generator including a permanent magnet rotor, a toothed stator and at least two non-overlapping windings associated with the teeth of the stator. Each winding is substantially similar to but independent of the other winding or windings. An end of each winding is separated from an adjacent end of an adjacent winding by at least one tooth having thereon a short-circuited low-resistance winding. g

A color display matrix array having parallelogram shaped display elements and the elements in one row all have a slant to the right, while the elements in the immediate adjacent row have a slant to the left.

An AC generator comprises a rotor 25 within a stator 24. The rotor carries a fan 27 at one end of the stator. The fan 27 is within a casing 30 which forms volume discharge passages 32. The fan 27 has blades 31 which project from the hub 28 at an angle which is oblique to the radial whereby those blades 31 trail the radial. The stator windings 23 form terminal leads 34 which are led from the end of the stator 24 remote from the fan 27. A circumferential array of cleats 35 which each have the form...

A conductor of a stator coil 18 is formed of oxygen free copper and the conductor end acting as a neutral point of the stator coil 18 is protruded from a coil end portion 18b and the tip end of the conductor end is bonded from above by arc welding to configure a neutral connection portion 20.

A low duty ratio mask has a plurality of masked layout patterns and a plurality of alternating scattering bars placed next to edges of each masked layout pattern. A phase shift of 180.degree. exists between the alternating scattering bars and the corresponding masked layout pattern.
