Inventor: REISMAN ARNOLD
IPC: H01L21/8226
Filed: 1981-07-06
Abstract: In a planar semiconductor integrated circuit, a buried isolating layer (9) confines equal area PN junctions of a vertical bipolar transistor (3) and a lateral bipolar transistor (5) to the intrinsic regions of the transistors. This avoids the formation of parasitic PN junctions and so leads to improved performance when the transistors are operated in saturation as in TTL circuits. A method of making such an integrated circuit involves the simultaneous deposition of polycrystalline semiconductor on the isolating layer and monocrystalline semiconductor onto the substrate through holes in the isolating layer. Alternatively, a thin nucleating film may be first deposited on the isolating layer so that monocrystalline semiconductor can be deposited on the isolating layer as well as on the substrate.

Abstract: In a brake actuator device, wear of brake lining, which results in the increase of stroke of the brake actuator device consisting of piston and cylinder, is compensated by an adjuster which functions automatically when the brake is operated. The adjusting process takes place continuously and preferably at the onset of the actuation of the brake. A slip clutch turns the adjuster member which is connected by screw threads to the brake actuator piston to take up slack in the piston stroke. The slip clutch is driven by a rotary member that is in turn operated in response to actuation of the brake actuator.
