In a multi-denominational stepping-tube counter, carry is inhibited when a train of pulses is applied to all denominations to step all the tubes through a complete cycle and read out the number registered. The counter is as described in Specification 1,017,406 except that the gate between successive denominations includes diode D3, and circuit C2, R9. With switch S1 set to count, counting takes place as described in said Specification. When a count has been registered and switch S1 is set to read-out, however, the extra circuit disables carry. When a train of ten pulses is then applied to the counter all the tubes Vu, Vt, Vh complete one cycle. Simultaneously the ten pulses are applied alternately to gas tubes E9-E0 which act as a control ring counter operating in reverse direction to bias the cathodes of digitrons Iu-Ih. When the discharge in a counting tube reaches cathode K9 the related transistor Tr2 conducts whereupon the related digitron also conducts to the marked cathode so illuminating the digit registered in the counting tube. If successive trains of ten pulses are applied the glow persists. Modifications. The gas discharge tubes in the control counter of Fig. 4 may be replaced by silicon-controlled rectifiers SCR, Fig. 9, or each stage may have a PN diode D8 and a PNPN diode D9, Fig. 10.

Abstract: 1395033 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 17 March 1972 [20 March 1971 18 June 1971] 49276/74 Divided out of 1395032 Heading H1K In a photo-transistor T 1  in which the emitterbase junction 19 is forward-biased by the absorption of radiation (e.g. visible, infra-red or ultraviolet light) generating electron-hole pairs which separate across the junction 19, the collector region 14 overlies and is surrounded at the irradiated surface 6 by the region 13, and the emitter region 12 underlies the emitter and base regions and is of greater lateral extent than the emitter region 12. The base-collector junction 18 may be shielded against irradiation by an extension of the collector electrode 17 as shown, or may be constituted by a self-shielding Schottby electrode (Fig. 8, not shown). In the illustrated embodiment the emitter efficiency is improved by the provision of a high resistivity portion 12a of the emitter region between the base region 13 and a lower resistivity portion 12d of the emitter region; the portion 12a may completely surround the base region 13 as shown, or may be omitted where the base region 13 adjoins isolating walls 4 of the same type as and adjoining the emitter region. Surface adjacent portions of the highly doped walls 4 may extend into the base region 13 towards the emitter electrode 16 and the base-collector junction 18 (Fig. 9, not shown). There may be a plurality of separate collector regions (Fig. 10, not shown). The base region may be divided by an upward extension (74), Fig. 11 (not shown), of the high resistivity portion of the emitter region (72). Then, if separate electrodes are applied to the two portions (70, 71) the structure effectively constitutes a lateral photo-transistor 70/74/71 in addition to the main photo-transistor, the collector-base junction of the former device being subject to illumination. The phototransistor T1, Fig. 7, is preferably one of three sharing a common emitter region in an integrated circuit (Specification 1,395,032, Division H3). Irradiation may be affected by an incandescent or discharge lamp, daylight, or by a PN recombination radiation source integrated into the semi-conductor structure. As an alternative to the diffused isolation walls 4 lateral isolation between the transistors may be effected by zones of inset oxide. Fig. 5 (not shown), illustrates a phototransistor lying outside the terms of the present invention and described and claimed in Specification 1,395,034)

A remotely controlled external rear-view mirror head 14, Fig. 1, is adjustably secured to one end of a support lever arm 10 provided at its other end with a hemispherical projection 9 pivoted by a horizontal pin 19 to the upper hemispherical end 7 of a half-round carrier shaft 8, the sphere formed by the two parts 7, 9 being seated in an elastic bearing ring 6 provided around an opening in the top of a door panel 1, whilst the lower end of the shaft 8 is supported rotatably and vertically by a bracket 33, secured at 35 to an inner panel 3 of the door. The part 9 is recessed to receive the upper end of a control lever 20 extending along the rod 8. The lower end of the lever 20 has a slot 21 to receive a crank-pin 23 of a crank-arm 22 having a shaft 24 rotatable in an eye 16 on the rod 8. The shaft 24 has a hexagonal-sectioned bore to receive a hexagonal-sectioned manual adjusting shaft 29 provided with a knob 30, the shaft 29 passing through horizontal slots 25, 25 in the door panels 2, 3. By rotating the shaft 29 about the longitudinal vertical axis of the rod 8 the mirror head and arm 10 is also rotated about a vertical axis. If the shaft 29 is rotated about its longitudinal axis, the crank 22 causes the lever 20 to rotate about the pin 19 and thus rotate the mirror head and arm 10, about a horizontal axis. The rotation of the rod 8 is effected against the friction of a tapered bearing member 38 urged into a tapered hole in the bracket 33 by a spring 27 controlled by a nut 31 screwed on the end of the shaft 8. The rotation of the crank-arm 22 is resisted by a tapered disc member 17 secured on the shaft 29 by a pin 18 and engaging a corresponding surface of the eye 16 under the urge of a spring 28. The latter also urges a cover-plate 37 against the slot 25 in the door panel 3. In another embodiment described with reference to Figs. 4 and 5 (not shown), the crank-arm is replaced by a pinion engaging teeth formed on the lower side of a generally rectangular aperture in a member carried by the lower end of the lever 20.
