Abstract: 982,413. Hydraulic pumps. WEATHERHEAD CO. Nov. 17, 1961 [Jan. 12, 1961], No. 41329/61. Heading F1A. The output of a swash plate pump with an axially movable cylinder block 60 is varied by controlling the effective area of the inlet ports 84. The pistons 65 reciprocate in cylinders 62 formed in a slidable cylinder block 60, adjustment of which varies the distance of the end face 84 of the inlet slots from the end face 66 of the pistons at the end of their outstroke and thereby varies the throttling of the inlet ports and controls the amount of fluid entering the cylinders. The fluid is discharged through outlet valves 103 into a common outlet 107, the pressure in which controls the position of the cylinder block. As outlet pressure increases, a valve 135 with a land 133 thereon is moved to the right to admit fluid through space 131 and passage 154 to a space 123 in a cylinder attached to the cylinder block, whereby the block is forced to the right against spring 111 to throttle the inlet ports 84 and reduce pump output. Upon a decrease in outlet pressure, valve 135 returns to the left to connect space 123 to an exhaust outlet 156 and cylinder block 60 returns to the left to increase output until equilibrium is established when land 133 is in the position shown.

Abstract: 1,237,712. Semi-conductor devices. MULLARD Ltd. 30 Aug., 1968, No. 41475/68. Heading H1K. The collector region of a high-switching speed transistor formed in an epitaxial layer on a substrate 1 has a highly doped part lying directly under the collector-base junction comprising a first portion 11, under that part 8 of the junction which lies directly below the emitter region 5, closer to the free surface 2 than a second portion 12 below an adjoining second part 9 of that junction. The doping concentration of the impurity in the collector region or base region at positions adjacent to the second part 9 of the collector-base junction is smaller than each of the doping concentrations of the impurity in the collector and base regions at positions adjacent to the first part. 8 of the junction. This configuration combines a low collector series resistance with a low collector-base junction capacitance. The highly doped part of the collector extends to the surface 2 and a collector contact 24 is provided together with contacts 21 and 22 for the emitter and base. The epitaxial layers which are silicon may be deposited in specially prepared cavities in a silicon body, the highly doped portion of the collector having been previously formed into the cavity surface 4 by diffusion or ion implantation. The epitaxial deposition may be carried out in one or two stages, and in the latter case the second layer has a higher resistivity than the first layer. Impurities used as dopants are boron, phosphorus and arsenic. In the case of transistors forming part of an integrated circuit, the contacts, of aluminium, provide conductive paths over the insulating layer 3 of silicon oxide. The devices are separated by reverse biased PN junctions and a highly doped surface region 27 is present to prevent parasitic inversion channels. Various configurations of device are described.

Abstract: 1,202,543. Photo-multiplier circuit. COMMISSARIAT A L'ENERGIE ATOMIQUE. Sept.15, 1967 [Oct.5, 1966], No.42137/67. Heading G1A. [Also in division H3] A method of selecting wanted pulses u having a long time constant fall time from spurious pulses P having a shorter time constant fall time comprises amplitude limiting and integrating the pulses so that the wanted pulses u are of greater amplitude than the spurious pulses P, then selecting the pulses u by means of an amplitude discriminator. The invention is applicable to separating wanted pulses u from a photo-multiplier from spurious pulses P which may be due to thermal agitation, ionization of gas or cosmic radiation. Pulses from a low resistance anode load, Fig. 8 (not shown) of a photo-multiplier are amplified by a cascode transistor amplifier, Fig. 9 (not shown) having an inductive collector load and passed via further transistor amplifiers (such as 44) to a clipping transistor 46, operating with grounded base and arranged so as to reduce the amplitude to one half in the case of the smallest amplitude pulses. The output of transistor 46 is amplified at 16 and fed to an integrator, Fig. 11 (not shown) the output of which is coupled by a further transistor amplifier to an amplitude discriminatior of unspecified type. It is stated that the invention can provide pulses to the amplitude discriminator in the ratio of 3:1 from initial pulses having an amplitude ratio of 1:15 and fall time constant ratio of 0À1:1.
