Abstract: 1,257,318. Protecting transistors from overload. SONY CORP. 20 Nov., 1968 [21 Nov., 1967], No. 55065/68. Heading H3T. A circuit for protecting a transistor from overload comprises means for limiting its current in dependence upon the voltage across and current in the transistor, the rate of increase in the voltage dependent component being reduced above a given level. As shown, a transistor X 2  for limiting the drive to an output transistor X 1  becomes effective when the base-emitter threshold of conduction of X 2  is exceeded by the sum of the voltage across 6 which is dependent upon the current through X1 and the voltage across a resistor 5 of a potentiometer 8, 4, 5 which is dependent upon the voltage across X1. A Zener diode 10 in series with a resistor 9 reduces the rate of rise of the voltage dependent component when the diode becomes conductive so that maximum dissipation characteristic more closely follows the curve of maximum allowable transistor dissipation.

The copolymers are obtained by treating a compolymer of acrylonitrile with a monomer having, or being capable of producing a hydroxyl group, e.g. in an aqueous acid medium, so as to effect lactonization. Suitable hydroxy or hydroxy-yielding monomers include allyl alcohol, methallyl alcohol, vinyl ethers, allyl ethers, vinyl esters, allyl esters, methallyl esters and isopropenyl esters. The copolymers may also include units of a halogen-containing monomer, e.g. vinyl chloride or bromide or vinylidene chloride as well as of other comonomers such as allylsulphonic or methallylsulphonic acid or a salt thereof, or styrene. In examples, filaments are spun from aqueous thiocyanate or dimefhylformamide solutions of the copolymers, and these are then stretched in boiling water or polyethylene glycol, dried and heat-treated in superheated steam.

As shown, the assembly 11 is a double Dove prism arrangement driven by a motor 18. The film is driven from spool 15 to spool 16 across the variable slit 13 whose width is controlled by a motor 20. Image motion compensation corresponding to aircraft movement when the camera is used in an aircraft is provided in the along track direction by a motor 21. Across track control by motor 22 compensates for angular motion of the prism assembly. The magnification of the zoom lens assembly 12 is controlled by the position of the movable lens element as determined by the drive motor 19. In arrangements having a lens of fixed focal length, the magnification of the lens decreases with increasing angle of sweep of the prism assembly as the object distance increase. Thus the image becomes compressed towards the ends in both the across track and along track directions, Fig.2a (not shown). This is compensated for in the present arrangement by varying the magnification of the lens system. Motors 19, 20, 21 and 22 are all controlled from a central control 17 which receives a signal representing the aircraft velocity/height ratio, and also a function of the prism scanning angle from a pickoff device 25. Thus the lens magnification, slit width, and film transport in the along and across track directions are all controlled in synchronism in a co-ordinated manner.
