Abstract: 1,209,914. Semiconductor devices. MARCONI CO. Ltd. 22 Feb., 1968 [29 March, 1967], No. 14335/67. Heading H1K. During manufacture of a semi-conductor device an oxide coating on a Si body is covered with a layer of gettering material, e.g. phosphorus glass, and heated so as to out-diffuse impurities from the oxide coating, after which the gettering layer is removed and the subsequent stages of electrode application &c. are performed at a relatively low temperature (# 500‹ C.) so that no recontamination of the oxide coating occurs. The invention is described in relation to a Si MOS transistor having boron-diffused source and drain regions, and evaporated A1 electrodes: When the phosphorus glass layer is removed by etching after gettering has taken place at 1000‹ C., a small amount of the underlying oxide coating may also be removed. An n-channel device is also referred to. A prior art manufacturing process is described in which the phosphorus glass gettering layer is retained over the oxide coating on the completed device.

As described the compressed fluid is a refrigerant and the parameter may be inlet or outlet temperature or pressure, or temperature in the evaporator or of a coolant associated with the compressor. The relay 60 provides no output when its input signals are balanced but otherwise energizes one of two lines 67, 68 to open a corresponding one of solenoid valves 41, 42. Hydraulic fluid is then allowed to flow to or from a chamber 27 on the right hand side of a piston 26 fixed to the slide valve 20. Return force on the slide valve is provided by a spring 15.

A rotary or reciprocating rotary motion may be imparted to the mould, dummy-bar and charge 1 to ensure a uniform thickness of the refined outer shell. When the ingot formed is of rectangular cross-section, the plasma torches 5 are given a reciprocating movement so that the distance between them and the ingot remains constant during the rotary movement of the latter. Alloying additives and a flux may be fed to the surface of the molten metal bath 6 during the process which may be carried out in an atmosphere of argon, helium, hydrogen, or nitrogen, the latter resulting in the formation of an ingot having a nitrogen-alloyed outer shell and a nitrogen-free core.

Filed: 1936-05-27
Abstract: 455,346. Pneumatic despatch apparatus. LAMSON PNEUMATIC TUBE CO., Ltd., and BURL, H., 132, Cheapside, London. May 27, 1936, No. 14971. [Class 78 (i)] A chamber 4 is connected to a despatch terminal 1 of a pneumatic despatch tube adjacent the door 2 and is provided with a valve 6 slidably mounted on a piston rod 7 which itself is slidably mounted in guides 10a, 11, the latter being secured to a diaphragm 9. The lower part of the chamber communicates with atmosphere through an opening 5 and a piston 10 is secured to the upper end of the rod 7. When the system is out of use a pin 15 is projected into the part of the valve 6 to limit its downward movement, but when the system is operative the pin is retracted against a spring 18 by suction in a subsidiary pipe 20 acting on a diaphragm 16. When the door 2 is opened the vacuum in the chamber 4 is destroyed and the valve 6 falls down the rod 7 and atmospheric pressure is admitted to the chamber 4 and suction pipe. When the carrier reaches its destination the suction causes a rush of air past the piston 10 whereby the latter and the rod 7 are raised until a projection 12a on the rod contacts with and closes the valve 6. A valve 12 in the diaphragm 9 is closed by a plate 13 on the rod as the latter rises and the diaphragm is flexed upwardly, an adjustable air-inlet valve 14 in the chamber beneath the diaphragm controlling the rate of upward travel of the piston. The valve 6 remains closed under the atmospheric pressure on its lower face and the piston 10, rod 7 and diaphragm 9 now descend under their own weight thereby resetting the device ready for the insertion of another carrier. The initial downward movement of the piston rod opens the valve 12 whereby the downward movement is continued unrestrictedly.

Abstract: 235,242. Pantoflicek, B. June 9, 1924, [Convention date]. Projectile fuzes. - A percussion fuze which acts directly when the shell strikes the objective nose first, and also operates by rebound of the striker when the shell strikes base first, includes a spring plunger 15 which absorbs the rearward momentum of the striker and throws it forward to cause ignition of the cap 22.

If the shell strikes base first, the striker 13 receives its forward firing movement by the rebound of the plunger 15 transmitted through a ball 14. The forward movement of the striker 13 permits of the lateral escape of balls 23 and the release of a secondary spring striker 24 which fires the cap.
