摘要： 1,231,528. Light responsive circuit. ATES COMPONENTI ELETTRONICI S.p.A. Nov.26, 1969 [Nov.26, 1968], No.57819/69. Heading G1A. A light responsive circuit, Fig .1, substantially independent of temperature and supply voltage variations includes a photo-diode F. D .1 which controls the input of an amplifier, the amplifier comprising a first transistor Q 1 connected in the common collector mode and arranged to control the signal applied to the base of a second transistor Q 2 the first and second transistor being connected so that the signal between the points A and B is equal to the difference between the base emitter potentials of the two transistors (causing the transistors to be independent of temperature variations). The circuit components are arranged so that the photo-diode F. D .1 and the transistor Q 1 , Q 2 are effectively in the diagonal of a resistance bridge WXYZ (ensuring the circuit is substantially independent of supply voltage variations). A relay RL 1 is controlled by the output from transistor Q 4 , Q 3 and Q 4 forming a second amplifying stage, such that when the ambient light impinging on photodiode F.D.1 falls below a predetermined level, the relay RL 1 operates, for example, to turn on the side lights of a vehicle, and, simultaneously the contacts rl, of a further pair of normally open contacts, are closed. The closing of the contacts rl, applies a signal to the emitter of transistor Q 4 which requires that the level of light impinging on the photo-diode F.D.1 should rise above the first predetermined level to a second predetermined level before the output signal of the circuit as a whole is removed, i.e. before the side lights are switched off.

[Also in Division G1] A photo-electric receiving device comprises a cylindrical anodized aluminium housing 1 in which is embedded in epoxy resin 9, a silicon planar microphotodiode 6 and a silicon planar transistor 7. The photo-diode 6 is connected across the collector/base junction of the transistor 7 and the output leads 1A, 1B are connected to the collector and emitter of the transistor. The device may be connected in series with a relay and a source of current to operate the relay in response to infra-red light on the photo-diode. The photodiode preferably has pentode-like charcteristics.

摘要： 1,095,745. Photo-electric devices. FAIRCHILD CAMERA & INSTRUMENT CORPORATION. Nov. 30, 1966 [Feb. 23, 1966], No. 53730/66. Heading H1K. [Also in Divisions H3 and H4] A radiation sensitive circuit comprises a transistor, one junction of which is charged and then discharged by incident radiation so that the magnitude of the next charging pulse indicates the magnitude of the radiation. The collector-to-base junction 14 of a double diffused type transistor is charged by a negative pulse during #t. At the end of the pulse the voltage across the junction due to the charge maintains the emitter junction non-conductive so that such discharge as occurs is mainly due to incident radiation. The next pulse recharges the collector junction and produces a corresponding but amplified signal in the output means.

摘要： 1,163,063. Photo-electric sample analysis. KOLLMORGEN CORP. Feb. 6, 1967 [July 18, 1966], No.5527/67. Heading G1A. [Also in Division H4] In an arrangement in which a sample 16, Fig. 1, is investigated by light from a pulsating source 10, output noise arising from source pulse-amplitude variations is suppressed by developing a signal from the light pulses and applying it to vary the output signal from the photo-sensor either as developed or subsequently, the lamp may be a pulsed xenon arc and the light is focused to fall on the surface of a sample 16 or standard 15, according to the position of a rotating mirror M3, by an optical system comprising lenses L1, L2, and apertures A1, A2, 8% of the light energy being deflected by a partly silvered mirror M2 on to a pair of source monitoring transducers 20, 21 to develop the noise suppression signal. The light reflected or transmitted by the sample according to the nature of the test is applied alternately with that reflected or transmitted by the standard, to a photo-multiplier 25. The rotation of mirror M3 activates a switch 13 to appropriately pulse the source, and a switch 27 to direct the outputs representative of the standard and sample to appropriate circuits, each including a "boxcar" and an amplifier A1, A2 for comparison. Long term stabilization of the system is provided by a feedback on which the D.C. high voltage supply 40 to the photo-multiplier is adjustably controlled by the pulse height of the signal related to the standard, a tapped off portion of the signal across a potentiometer 36 being compared with a reference voltage in a comparator 41. The source monitoring photosensors may be photo-conductive, or photo-voltaic, and may control the potential on a further dynode of the photo-multiplier, may be connected in series or in shunt across the main sensor load circuit, or may control the gain of an amplifierin the main output path. More than one monitoring photo-sensor may be used in these circuits, and the sensors may comprise double-junction silicon diodes. In an arrangement carrying out a spectral test and using a plurality of photo-sensors all the sensor outputs may be controlled by a single monitoring sensor. In an amplifier gain control circuit, Fig. 6, the main and monitoring inputs are applied alternately, and the latter sets the impedance of an FET to determine the amount of feedback which is then maintained by a capacitor C1 whilst switches S1 S2 are in the "a" position. The switches may be solid state devices.

摘要： 1,145,897. Electron multipliers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 1 Aug., 1966 [4 Aug., 1965], No. 34356/66. Heading H1D. In an electron multiplier with a collector grid 3 between the last two dynodes 1, 2, the output is taken from the last dynode 2 and the collector grid 3 is decoupled from earth by a capacitor 7 in order to avoid perturbation of the electron beam impinging on the last dynode. The collector grid 3 and the last dynode 2 are within a focusing shield 4 and the output is taken via coaxial cable 5, 6 as shown. The capacitor 7 may be within the vacuum enclosure. The capacitor may comprise a structure of mutually insulated plates pressed together to form a plurality of capacitors which can be connected in parallel. The last dynode may be connected to earth by a resistance.
