Title: Field effect device with overlapping insulated gates
IPC: H01L21/316
Filed: 1967-05-16
Abstract: 1,138,771. Field-effect transistor. HUGHES AIRCRAFT CO. 16 May, 1967 [1 July, 19661, No. 22703/67. Heading H1K. A field-effect transistor comprises a semiconductor body having spaced source and drain regions at a common surface thereof, a first gate electrode insulated from the surface and extending from the source partially over the channel region and a second gate electrode insulated from the first gate and the surface and disposed over the first gate and the surface between the source and the drain. A twogate field-effect transistor is made from a wafer of p-type Si 2  by diffusing in boron through an oxide of silicon mask to give a circular drain region 12 and a source region 10 surrounding an annular channel 8 (Figs. 1-3, not shown). The oxide mask is removed and a complete oxide covering 6<SP>1</SP> provided by oxidation in steam. A film of Al, Cr or Au is vapour deposited and etched away to leave a first gate region 14. Another oxide covering 18 is formed by pyrolytic decomposition of an alkoxy silane or by sputtering glass or silicon oxide (Figs. 4 to 8, not shown). Using resist-masking and etching techniques layer 18 is removed to expose the source and drain regions 10 and 12 and also a tab of the gate electrode 14 (Fig. 9, not shown). Vapour deposition of Al over the entire surface with subsequent resist-masking and etching yields an IGFET having source and drain contacts 19<SP>1</SP> and 20<SP>1</SP>, first gate contact 28 and a second gate 26. A device having the opposite polarities may also be fabricated. Miller feedback capacitance for the device is very low.

Title: Improvements in or relating to apparatus for examining thermal conductivity
Inventor: THOMAS ARTHUR
IPC: G01N25/18
Filed: 1953-08-20
Abstract: 927,555. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Aug. 20, 1954 [Aug. 20, 1953], No. 23035/53. Class 39 (4). [Also in Groups XX and XXXVIII] Apparatus for testing the thermal conductivity of a body, e.g. a nuclear fuel element, comprises means for heating a bath of liquid to a predetermined temperature, means for indicating whether or not the insertion of the body in the bath causes the temperature to fall to a given value within a given time, and means for indicating the removal of the body before the given time has elapsed. The Figure shows a bath 1 containing a liquid such as glycerine which is heated to a predetermined temperature (210‹ C.) at which controller TC turns off the heating current and lights lamp L3. Insertion of a body closes switch 5 and energizes relay A. Relay A then engages magnetic clutch MC and breaks the heating current circuit and the circuit of a relay CR. The magnetic clutch couples a timing cam C to a continuously running synchronous motor, and simultaneously contacts ON1 in the circuit of relay CR are closed. If the temperature falls by the desired amount (20‹ C.) before the end of the given time (30 sec.), controller TC energizes relay B, which closes contacts to hold itself on and to operate lamp L2 and buzzer 14 and breaks the circuits of lamp L1 and relay CR. If the time ends before the temperature falls by the desired amount timing cam C closes a circuit to energize a relay CL which then holds itself on, closes contacts in the circuit of lamp L1, and breaks the circuits of relay A, lamp L2 and buzzer 14. Consequently operation of L2 and 14 indicates a satisfactorily high conductivity, while operation of lamp L1 indicates that the conductivity is too low. If the body is removed before the end of the time and before the temperature has fallen acceptably, the circuit of relay A is broken and the circuit of relay CR is thereby completed, since relay B is still unenergized. Relay CR then holds itself on and lights warning lamp L4 and sounds bell 12 until turned off at KRA.

Filed: 1951-10-05
Abstract: 706,360. Solid fuel burners. VALOR CO., Ltd. Oct. 2, 1952 [Oct. 5, 1951], No. 23204/51. Class 75 (1) A solid fuel burner of the perforated shell type comprising two concentric perforated tubes 19, 25 has the primary combustion effected in a space above the fuel in close proximity to an inner tube 11 of good heat conductivity. Thus a central air draft tube 11 passes up through the fuel and on this is supported the inner perforated tube 19 ; the fuel reservoir is larger than the mass of the fuel it is designed to contain in order to leave a chamber 13 into which the inner perforated tube 19 depends and which accommodates the increased volume of vaporized fuel. The tube 11 of copper or similar material is shouldered at 18 to support the inner perforated tube 19 and has round or elongated air holes 20 therein below the shoulder. A direct air supply or igniting hole 29 in the wall 16 of the reservoir is closed by a pivoted shutter 30 or by a thermostatically controlled closure member.

Abstract: 701,018. Semi-conductor gating circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 5, 1951. [Oct. 12, 1950], No. 23285/51. Class 40 (6) A switching circuit comprises two oppositely poled series rectifiers (preferably of the drycontact type) and a shunt rectifier connected to the common point of said first two rectifiers, and means for applying a switching potential to said common point, whereby the series arm is conducting and the shunt arm non-conducting or vice versa in accordance with the value of the switching potential. As shown, Fig. 4, two parallel T-networks are provided for gating signals of positive and negative polarities respectively. Normally the upper T-network is closed due to the back biasing of rectifiers 12, 13 from the source 16 and the forward biasing of rectifier 20 due to the point 16 being at a higher biasing potential than the point 17. If, however, a negative pulse of sufficient amplitude is applied to the point 26 rectifiers 12 and 13 become forward biased and rectifier 20 becomes back biased. The upper T-network will then pass positive signals from point 1 to point 3 but negative signals will be subject to clipping. A circuit comprising oppositely poled diodes 14, 15 and 23 and fed at point 29 with positive pulses is therefore provided for gating the negative signals. In the arrangement shown in Fig. 6 the gating pulses are derived by connecting a single source of pulses to a transformer 33 having two oppositely poled secondary windings for pulsing the upper and lower T- networks. If the rate of pulsing is sufficiently rapid the biasing source at 16, 17 may be dispensed with, the biasing voltage being derived from the condenser 38 which is charged by the rectifying action of the diodes on the pulses. In a further embodiment, Fig. 7, two identical T- networks are connected between corresponding pairs of terminals of the input and output transformers 39, 40. The networks are pulsed from a common source over resistors 41, 42. Capacitors 46, 47 provide a low impedance path for the pulses if the transformer 39 is designed for low frequencies and would consequently present a high impedance to the pulses. Specification 482,103 is referred to.

Abstract: 1,187,451. Testing banknotes &c. MITSUBISHI JUKOGYO K.K. 24 May, 1967 [26 May, 1966], No. 24254/67. Heading G4R. [Also in Division G1] Whether printing on a test article (e.g. banknote or security) is the same as printing on a model article is tested by scanning the two articles in synchronism to obtain two model signals, similar but relatively time displaced, representing the printing pattern on the model article, and a test signal representing the printing pattern on the test article, the test signal being polar correlated with each of the model signals, the results of these two correlations being compared. If the correlation results differ sufficiently, the test and model articles are the same. The scanning is done by three heads (one for the test article, and two for the model article) past which the articles are driven, the heads being photo-electric (receiving light transmitted through the articles) or magnetic, and sense in a slit area whose long axis is transverse to the direction of movement of the article. The D.C. components of the electric waveforms from the heads are removed prior to the correlation. In the optical case, this removes effects of lamp and photo-cell ageing.
