Title: Improvements in Storage Mode Photodetector with Electronic Shutter Action
IPC: H03K17/78
Filed: 1967-06-05
Abstract: 1,153,259. Photo-electric detector circuit. FAIRCHILD CAMERA & INSTRUMENT CORP. June 5, 1967 [Aug.8, 1966], No.25792/67. Heading G1A. [Also in Divisons H1, H3 and H4] In a storage mode photo-detector device with electronic shutter action i.e. one in which a signal corresponding to the intensity of radiation and a predetermined exposure time is stored prior to readout the photo-sensor comprises at least one P-N junction device in which a charge is dissipated by exposure for a predetermined time to the image at which it is directed, and a signal corresponding to the diminution of charge in the storage mode device is stored in a further semiconductor device having at least one P-N junction the photo-sensitive area of which is protected from radiation, and coupling means are provided between the photo-sensor and the further signal storage device to effect signal transference at selected intervals, provision being also made for reading out the stored signals at selected intervals which may be different from the storing intervals. A charge is repetitively applied to a photo-sensitive transistor 10, Fig.1 by a pulse generator 16, and the bases of the transistor 10 and a storage transistor 20 are coupled by a metal oxide semiconductor channel transistor 15 for a predetermined time after a predetermined exposure to radiation of transistor 10 to effect a redistribution of the joint charges on the two. The current flow during subsequent re-charging of transistor 20 by a further pulse generator 18 provides an output across a load resistor 6. A modification using a pair of diodes which are charged from a battery source has a pair of coupling transistors between the two diodes and between the signal storage diode and the battery. The generator pulses in this arrangement are connected directly to the gating electrodes of the respective coupling transistors. Solid state integrated components are described for the two arrangements the first comprising two N.PN devices having a common silicon substrate 41, Fig.5 covered by an insulating layer 48 on which is deposited the gating electrode 49 of the M.O.S. transistor, and an opaque layer 50 to protect the transistor 56 from incident radiation. In a modification three "p" type deposits are made in a common substrate and the insulating layer carries two gating electrodes spanning the three deposits and opaque screening for two of them. The device is used as a basic element in a solid state vidicon and as many as 200 devices to the inch may be used. A matrix is described with reference to Figs. 7 and 8 (not shown) in which the photo-sensors and signal storage are connected to the pulse generators by respective common buses and in which the stored signals are read out under the control of a clock pulse generator producing row and column sampling pulses.

Filed: 1951-11-08
Abstract: 706,365. Fishing tackle. HENSHAW, W. S. J. Nov. 8, 1951, No. 26130/51. Class 48 In a line fishing tackle a bead f slidable on the line between a fixed stop e and an adjustable stop k actuates, on winding in the line, a movable part n of a ledger to release a sinker q except when obstructed by a second movable part g of the ledger, this second movable part being adapted to fall out of engagement with the line when the tackle attains the fishing position. The ledger is made of wire; its movable part n to which the sinker is releasably secured is in the form of a bolt slidable in two eyelets p, o formed in the main part of the ledger. The second movable part g is hinged at r to the main part of the ledger and comprises prongs between which the line passes but which are too close together to permit passage of the slidable bead f. In the position of the tackle before casting, Fig. 1, and in mid-flight, Fig. 2 (not shown), the movable part g prevents the bead from engaging with an eyelet i formed on the actuating arm m of the bolt, but when the tackle reaches the sea bed a float a to which the end cf the line is attached erects the ledger into the position shown in Fig. 3 and in this position the line slips clear of the prongs of the gate so that when the line is wound in the bead is carried into abutment with the eyelet i on the bolt arm m by the fixed line stop e and the bolt is operated to release the sinker. An eyelet j on the bolt arm m guides the line and an eyelet l on the ledger guides the bolt arm. The sinker may comprise pieces of stone, metal &c. or a bag filled with sand and closed by a draw string looped for attachment to the ledger. A paternoster is slidably mounted on the line and comprises separate wire booms b, c. d each having a vertical and a horizontal arm.

Filed: 1936-09-30
Abstract: 484,398. Controlling motor vehicles; facilitating changing speed. NEWTON, N. B. Sept. 30, 1936, No. 26493. [Class 79 (v)] [Also in Group XXIV] A power transmission system comprising in combination an engine, an automatic centrifugal clutch with voluntary de-clutching means, and variable speed gearing, is characterized by means interconnecting the de-clutching means with the engine speed control so as to maintain the engine speed at or above the critical speed of the clutch or to raise it to such speed during operation of the voluntary clutch control. In the construction shown in Fig. 1 the accelerator pedal b controls the throttle d through linkage e, f, g, and a lever c. The clutch pedal a disconnects the clutch when desired and also, through a link m, spring o, and link k rocks a lever h adapted to engage the lever c and open the throttle to an extent determined by an adjustable stop j. The spring o allows the clutch pedal to be depressed after the lever h abuts against the stop j. Thus, when the clutch pedal is depressed to disengage the clutch the throttle is opened sufficiently to increase the engine speed to the desired extent. In the construction shown in Fig. 2, the clutch pedal 11 opens the throttle only on its return movement to allow the clutch to re-engage. The pedal 11 actuates a piston 16 having an air leak 14 and working in a cylinder 13 connected by a pipe 17 to a cylinder 18 having a piston 19 which rocks a lever 20. When the clutch pedal is depressed the piston 16 travels idly in its cylinder, but when the pedal is released and returned by its spring 11b the piston forces air into the cylinder 18 and lifts the lever 20 against the stop 21a to open the throttle 23 before the clutch engages.
