Abstract: 1,018,787. Electrophotographic developing apparatus. RANK-XEROX Ltd. Dec. 31, 1962 [Dec. 29,1961], No. 49027/62. Heading G2H. An apparatus for developing latent electrostatic Images on a support comprises a stationary magnetic field producing means, a cylindrical shield formed of alternating sections of magnetic and non-magnetic material enclosing the length of the field producing means and spaced at least partially within the effective magnetic field of the means so as to physically prevent magnetic particles attaching themselves to the means, the shield having an exterior surface pattern to retain a quantity of developer particles so that they form a brush, a supply source for the developer particles and means to rotate the shield about the field producing means and between the supply source and the means whereby developer particles are attracted from the source to the shield surface. As shown, magnet 21 is mounted on stationary rods 22, 23 supported by blocks 24 and 25. Ball bearing rolls 30 and 31 are mounted on rods 22 and 23 and fit into sleeves 28 and 29 connected to shield 26 so that the shield can rotate about the magnet. The shield 26 has alternate magnetic portions 53 and non-magnetic portions 54 and a rough surface 34 so that the magnetic developer 27 can be held and prevent any relative movement of developer and the shield. After magnetically picking up the developer, the brush is moved across the surface of plate 10 bearing an electrostatic latent image. The plate 10 is preferably moving in the opposite direction to the shield 26 but may be stationary or moving in the same direction. Due to the shape of the magnet, the developer falls off shield 26 after passing plate 10 which ensures continuous mixing in trough 47. Shield 26 is preferably electrically insulating but may be conductive in which case a bias may be applied between the brush and plate 10. Magnet 21 may be ribbed, alternate ribs being north and south poles. Trough 47 has a hinged bottom wall 50 to dump the developer, and shield 26 has two semi-cylindrical sections held by hasps 32 and 33 so that it may be changed if a different developer is required.

Abstract: 1,242,675. Measuring bridge circuits. SERVOMEX CONTROLS Ltd and A. J. BORER. Oct.3, 1968 [Oct.31, 1967], No.49452/67. Heading G1U. [Also in Division G3] In a temperature responsive A.C. bridge circuit, a temperature sensor resistance RT is in series with a comparison resistor RS in first and second arms of the bridge respectively and the bridge is balanced by adjustment of a ratio transformer T1 having a first part in the third and a second part in the fourth arm. The number of turns in the first part is incrementally adjustable to define a divided temperature scale representing the measurement range of the circuit. Linearizing arrangements are provided to reduce non linearity in the relation between incremental turns variation and corresponding incremental variation in sensor temperature. These comprise a negative resistance device in parallel with the sensor and/or arrangements whereby the conductance of the second arm of the bridge and/or the number of turns in the fourth arm are pre-settable to values corresponding to each of consecutive sub-ranges making up the maximum measurement range of the circuit. The range of temperatures to be monitored are in the range -99‹-599‹ C. In one embodiment, Fig. 4, the ratio transformer section corresponding to the third bridge arm has three switching ranges, NA, NB, NC for the hundreds, tens and units respectively, linearly switchable through each range, while the section corresponding to the fourth bridge arm NS has a number of tappings switched in accordance with the hundreds, to rebalance the bridge In each of the ranges, to allow for the non linearity of the temperature responsive resistor. The hundreds switches for the sections NS and NA are ganged together. With this arrangement, correspondence between the linear adjustments in the windings NA-NC and the temperature to be measured is achieved to within 0À3‹C. The switches 4-6 are operated by the relay TR when temperatures below 0‹C. are to be measured, to rearrange the circuit so that negative values may be read directly. In an alternative system Figs. 1 and 2 (not shown) a negative resistance, formed by a positive resistor associated with a phase inverting transformer, is connected in parallel with the temperature sensitive resistor to provide a combined resistor whose variation with temperature is linear.

Title: A method of making a transistor device and a device so made
Inventor: HAERING RUDOLPH ROLAND
IPC: H01L29/786
Filed: 1964-12-07
Abstract: The modulation efficiency of a T.F.T. is made high by depositing the semi-conductor material in such a way as to obtain the lowest residual carrier density consistent with the absence of unfilled trap levels.  The presence of such unfilled levels would lead to reduced mobility because of their large scattering cross-section.  To reduce the residual carrier density the semi-conductor may be evaporated in an atmosphere containing a material which compensates for vacancies of that constituent of the semi-conductor material which is of higher vapour pressure. Alternatively a suitable dopant may be evaporated simultaneously with the evaporation of the semi-conductor.  To compensate for anion vacancies in cadmium sulphide and lead sulphide the atmosphere during evaporation may contain oxygen, sulphur or selenium, or a material supplying divalent anions which will substitutionally replace S".  Acceptor impurities which may be introduced into n-type cadmium sulphide or lead sulphide are Group Ib elements such as copper and gold.  Group III elements may be introduced as donors into p-type cadmium sulphide and group Va elements may be introduced as donors into p-type lead sulphide. The process may be carried out by sputtering or evaporation.  The manufacture is described of a transistor having a glass substrate bearing gold electrodes, cadmium sulphide semi-conductor, and silicon monoxide dielectric.  Calcium fluoride is an alternative dielectric. An evaporation apparatus is comprehensively described. The pumped chamber is connected to an oxygen supply (to compensate for S" vacancies).  Separate Drumheller evaporation crucibles are provided for cadmium sulphide, gold, silicon monoxide, and for an impurity material.  Each of the crucibles has its own heater and associated controller and has its own thermoelectric thermometer. A sector-shaped masking plate contains the four apertures needed respectively for the formation of the source and drain electrodes, the semi-conductor layer, the insulating dielectric layer, and the gate electrode.  The plate can be rotated between the crucibles and the glass substrate to select the desired mask.  While the source and drain electrodes are deposited the masking plate is held in a raised position against the substrate so that the gap between the source and drain electrodes is accurately defined.  For the deposition of the other component the masking plate is held in a lower position.  In this lower position the plate may be rotated so that probes fitted to one of its edges may be swept across the semi-conductor layer at intervals so that the resistivity of the layer may be monitored.
