Abstract: 1277863 Transistors RCA CORPORATION 24 Nov 1970 [20 Feb 1970] 55715/70 Heading H1K A power transistor comprises an annular base region which surrounds part of a collector region of opposite conductivity type at one face of a semi-conductor body. The base region consists of an inner annulus of high resistivity material with a plurality of radial lobes extending therefrom separated by inwardly tapering wedges of low resistivity material which merge into a peripheral ring. A plurality of emitter regions is provided each disposed in one of the lobes. In the embodiment (Fig. 1) a central emitter electrode deposited over a silicon oxide layer on the silicon body contacts all the emitter regions via slots in the oxide, the base electrode overlies the base region ring and has opposed bonding pad extensions on the oxide and the collector electrode is on the back face of the body. Several such structures may be formed side by side in the same body sharing bonding pads to which aluminium connecting wires are bonded. Alternatively the emitter electrodes are thickened to allow face bonding to a substrate with base and emitter connections on different levels. As described the collector region is an N epitaxial layer on an N+ silicon substrate and the two parts of the base and the emitter region formed in successive standard masked diffusion steps, boron nitride being used as the diffusant source for the base region. Electrodes are formed of aluminium by vapour deposition and formetching.

Abstract: This invention concerns a flanged half-bearing for motor applications. This half-bearing is of the type consisting of a semi-cylindrical shell, provided with half thrust washers suitable for the axial registering of the shaft, and reacting, therefore, to axial loads. The connection between semi-cylindrical shell and washers is obtained by hooking appended parts, substantially in convex prism form, present on each washer, between corresponding cavities arranged on the curved edges of the shell. Based on the angle position of the cavities, in relation to the axial plane of symmetry of the shell, and based on the shape of the cavities themselves and of the relative appendages, providing a slight interference in the coupling phase between shell and washer, and taking advantage of the flexibility of the shell, when mounted on the support, a coupling between shell and washer is obtained, which is stable before mounting in place and movable, circumferentially and axially, when mounted on the relative support. The inactivity of the hooking connection between shell and supports after mounting in place, permits the ideal adjustment of the supports themselves, axially and circumferentially.

Abstract: An improved apparatus for producing a glass ribbon and an improved method for subsequently coating said glass by pyrolytically depositing a metal oxide coating thereupon. The glass is produced in a molten metal float bath having a reducing atmosphere supplied at a slightly positive pressure which is comprised of a mixture of nitrogen and hydrogen gasses. The slightly positive pressure of the reducing atmosphere within at least one lock chamber of the float bath is reduced by venting at least one lock chamber to the outside atmosphere through apertures of reduced size each of which is located in a lateral exterior wall of at least one of said chambers which is separated from the float bath by at least one other of such chambers. Additionally, blower means may be provided to direct an inert antiflame gas, such as nitrogen, toward the base of an airtight curtain at the exit of the outermost lock chamber in order to reduce or totally quench the flames attributable to the burn-off of that portion of the reducing atmosphere which escapes therefrom.

Abstract: An anemometer (2) and solar (3) sensor (1) passes wind strength and solar intensity signals at regular intervals to the processor (4), for comparison with keyed-in levels (5). Processor commands pass to a radio transmitter (6). Power supplies are provided by the anemometer opt., by additional solar or wind generators with battery back-up (7), via gates (8,9) closed by the processor during sensor operation. The transmitter operates only when equipment actually requires alteration. Within the building the received radio signals are processed and appropriate commands passed to the mains-operated actuators concerned. Priority is given to wind data, to ensure immediate defensive reaction for vulnerable devices, overriding manual controls, in stormy conditions; if these are detected wind speed is rechecked every 2-3 minutes.
