Abstract: 393,273. Supply systems. KOLARZ, J., 10, Mautner-Markhofgasse, Rodaun, near Vienna. Nov. 25, 1931, No. 32708. Convention date, Dec. 23, 1930. [Class 38 (iv).] Power is transmitted and distributed over a desired area by establishing a high frequency electromagnetic field throughout the area. One or more conductors are excited by high frequency currents from the supply station and induce currents in other conductors connected to consuming stations, the transmitting and receiving conductors being so arranged as to produce a resultant field of annular form. The transmitting conductors'may consist of loops S, Fig. 1, disposed in vertical planes radiating from a centre, or of open ended conductors J, Fig. 6, arranged at the centre and at points spaced radially, and excited in such phase relationships as to produce the required annular field, the current in the conductors oscillating between large metal collecting surfaces K at their ends. In the first arrangement the loops may be divided into a grid-like structure, each loop of which is separately excited and may be so spaced as to leave annular zones in the supply area free from induction. Receiving loops E may have condensers connected to their terminals so as to produce wattless current in phase with that in the transmitting loops ; such receivers may be used to guide the field or to deflect it from specific regions, or even to produce the entire field. The transmitting loops may be fed by transformers of toroid form (with or without cores of finely divided or laminated iron), the primary circuits of which are in parallel.

Title: Improvements in or relating to a Method for Measuring Time Intervals and Apparatus including the Application of said Method
IPC: G04F10/04
Filed: 1966-07-21
Abstract: 1,157,986. Measuring short time intervals. COMMISSARIAT A L'ENERGIE ATOMIQUE. July 21, 1966 [July 29, 1965], No. 32929/66. Heading G1U. [Also in Division H4] In an arrangement for measuring the time interval between two points in a voltage waveform, the waveform is displayed on a double beam oscilloscope, which provides interlaced traces which are obliquely inclined and carry reference timing pulses to enable the interval to be assessed. The reference timing pulse at the end of each trace produced by one beam is arranged to correspond in time with the reference pulse at the beginning of the following trace produced by the other beam. Pulses from a generator 1 are passed to a divider 2 producing two pulse train outputs at 3 and 4, each corresponding to division by eight and arranged to be equally displaced relative to one another. The pulses are used to energise the line scan generators 5 and 10 to apply scan voltages to the plates 6 and 11 of the double beam tube, and also to control line return extinction circuits 7 and 12 which control the voltages applied to the tube grids. The end of one scan is arranged to slightly overlap in time with the beginning of the next, so that marker pulses at the end and beginning of consecutive scans overlap in time. A trigger circuit 15 controls the picture scan generating circuit 17, which provides two relatively inverted scan output waveforms. These pass to the mixers 23, 24 in each of which the test waveform is mixed with the scan waveform, while delayed pulses from the generator 1 are also added in the mixer 23. The outputs from the mixers are applied to the other pairs of cathode ray tube plates, connected in parallel. An ignition device 20 connected to the tube cathodes is controlled by the picture scan circuit 17.

As shown, Fig. 1D, a P<SP>+</SP> type ring 3 and an N<SP>+</SP> type region 2 are diffused into a P-type wafer 1, an N-type epitaxial layer 4 is deposited, a second P<SP>+</SP> type ring 5 is diffused above the first ring 3, a P+ type region 6 is diffused into the layer outside ring 5 and a small N+ type region 26 is diffused within ring 5, a second N-type epitaxial layer is deposited, two P+ type rings 9, 13 are diffused-in one above rings 3 and 5 and the other above the region 6, and the structure is then heated to redistribute the impurities so that the rings join up to form isolation walls surrounding N-type islands 11, 14. An NPN transistor is formed in island 11 by diffusing-in a P-type base region (15) and N<SP>+</SP> type emitter and collector contact regions (16, 17). A PNP transistor is formed using island 14 as part of the base region by diffusing-in an N<SP>+</SP> type base region (18) within which is diffused a P-type emitter region (19), the buried region 6 and ring 13 forming the collector region. The N+ type emitter and collector regions of the NPN transistor and the base region of the PNP transistor are formed by a single diffusion step. In a modification, Fig. 2 (not shown), the initial isolation rings are extended to enclose both islands in a figure-8 configuration and the portion containing the P+ type buried layer is processed to form an FET by diffusing a P-type gate region diametrically across the contacting P+ type ring and diffusing in N+ type source and drain regions. These P-type and N<SP>+</SP> type are formed simultaneously with the base and emitter regions of an NPN bipolar transistor formed in the other island.
