Abstract: 1499090 Field effect transistor INTERNATIONAL BUSINESS MACHINES CORP 28 Sept 1976 [26 Nov 1975] 40103/76 Heading H1K In a method of forming a FET comprising a silicon dioxide-silicon nitride composite gate insulating layer 4, 6, a layer 7 of a relatively high sensitivity material consisting of silicon oxynitride or silicon dioxide is provided at least between a relatively conductive silicon dioxide layer 10 covering side and upper surfaces of a polysilicon field shield electrode 8 and the silicon nitride layer 6 of the composite layer. The co-extensive portions of the field shield electrode 8 and the gate electrode 12 separated by the relatively conductive dielectric layer 10 may form a storage element. It is stated that the presence of the high resistivity layer prevents sub-threshold leakage current caused in the prior art FET by the inversion of the area of silicon substrate below the relatively conductive silicon dioxide layer. The high resistivity silicon oxynitride layer 7 is formed by annealing the silicon nitride layer 6 in oxygen atmosphere. The polysilicon field shield electrode 8 is formed typically by decomposition of silane in presence of diborane gas and the relatively conductive silicon dioxide layer 10 is grown by thermal oxidation of the doped polysilicon electrode 8. The highly resistive layer 7, typically 100  thick, may be of sputter deposited or chemically vapour deposited silicon dioxide. In a modification, Fig. 4 (not shown), the high resistivity layer 7 in the channel region is removed by preferential chemical etching prior to the deposition of the gate electrode which is of aluminium, aluminium-copper-silicon alloy or is a composite electrode of aluminium-polysilicon.

Abstract: 901,248. Control of A.C. motors. GENERAL ELECTRIC CO. Ltd. Nov. 15, 1960 [Nov. 27, 1959], No. 40431/59. Class 38 (3). [Also in Group XXXVIII] A two-phase motor 19 with permanent magnet or D.C. supplied rotor 20, e.g. for operating control rods in a nuclear reactor, is caused to operate in synchronism with the rotor of an induction regulator 1, either rotating at slow speed or locked stationary. The induction regulator has a primary winding 4 supplied with A.C. and two split secondary windings 5, 6 and 7, 8. Each half winding is connected in series with one of four equal A.C. reference voltages from a transformer 9 ... 12 and a rectifier 21, 22, 23 or 24. The maximum output from each half winding 5 ... 8 is equal to the reference voltages, and at any instant the voltage in one half winding boosts its reference voltage while that in its neighbour bucks it. The output from each rectifier thus varies between zero and twice the reference voltage according to the position of the rotor of the induction regulator, and will be a maximum for one when its partner is at zero. The rectifiers are connected to motor windings 15 ... 18 which are arranged in pairs to provide two fields in quadrature. Hence, a resultant motor field is established, stationary when the induction regulator rotor is stationary, and rotating in synchronism when the rotor is moved, e.g. by a motor 2 through gear-box 3. In an alternative arrangement the junction of motor windings 15 and 16 is connected to that of 17 and 18 and corresponding interconnection is made between the rectifiers, the polarity of one pair being reversed. The central connections from rectifiers to motor windings are then dispensed with. Specification 822,413 is referred to.

Abstract: 1382175 Testing ignition circuits VOLKSWAGENWERK AG 1 Sept 1972 [4 Sept 1971] 40624/72 Heading G1U An I.C. engine ignition circuit is characterized in that a relay contact 13a is provided in the lead to a sparking plug 1 and in that means are provided to open the contact 13a (and simultaneously to short the ht supply direct to earth via a contact 18a) for a pre-set number of cycles of the engine during which the degree of ionization existing in the plug can be determined by an appropriate device 35, which device produces a potential representing the resistance of the discharge path on a first output lead 36, and a pulse if the discharge current rises above a pre-set level, of e.g. 5 microamperes, on a second lead 37. As described ignition pulses 3 are shaped 4 and divided 5 by the number of cylinders in the engine to apply to gates 19, 29 one pulse for each cycle of the engine. In a "single shot" mode of operation, for which a mode switch 6 is set as shown, depression of a start key 7 causes a trigger 8 to apply a pulse to a control trigger 2. Control trigger 2 therefore reverses its state, relays 13 and 18 are energized via amplifiers 12 and 17 to open and close contacts 13a and 18a respectively and the test begins. Control trigger 2 also opens gate 19 which passes pulses, one per engine cycle, to a pre-set counter 22, 23, 24, 25, which after receipt of the pre-set number, resets both itself and the control trigger 2, so that the test ends. In the "repeat mode" of operation, with the position of switch 6 reversed, the control trigger 2 is repeatedly set to start a test by pulses received from a second pre-set counter 10, which receives its pulses via the gate 29, the first test period in a repeat mode commencing immediately switch 6 is changed over.
