Patent GB-2100513-A (GB)
Title: Darlington transistor circuit
IPC: H01L27/082
Filed: 1982-05-17
Abstract: In an integrated Darlington transistor circuit the gain of the output transistor T3 is reduced by heavy doping of its base region 6 so that its base region has a substantially greater concentration (e.g. ten times) of dopant than the base region 4, 5, of the or each driver transistor T1, T2. The BVCEO of the output transistor is close in value to its BVCBO so that the circuit can be made safe against avalanche breakdown for higher voltages than a conventional darlington circuit. The heavy doping of the base of the output transistor means that the sheet resistance of the region is low so that debiassing is small and it is possible to remove the base charge rapidly when the circuit is switched off. The circuit may include leakage current control resistors and speed-up diodes or transistors of known type. <IMAGE>

Patent GB-2149261-A (GB)
Title: Image processing apparatus
Inventor: MCEWEN ROBERT KENNEDY
IPC: H04N5/217
Filed: 1983-11-04
Abstract: Where the output of a particular detector element in a "staring" array has a value indicating a dead or seriously malfunctioning element it is convenient to replace it with an average value calculated from those output by the adjacent elements. A Shift Register 34 long enough to hold in predetermined locations N1-N4 the values output by all the suspect element's near neighbours (and all the ones inbetween the first and last of these in the read sequence) co-operates with means for replacing a "dead" element output value in the Register 34 with a calculated value 35 based on an average of those values in the defined neighbours' locations. Addresses of "dead" elements are determined during an initialisation stage and stored in microprocessor 36. The addresses are read out sequentially until agreement with an address in register 33 corresponding to the element being scrutinised is determined. The average value 35 is then written into the output value shift register. 34. <IMAGE>

Title: Flanged half-bearing for motor applications
Inventor: LOSIO GASTONE
IPC: F16C9/02
Filed: 1984-01-12
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.
