Title: Frequency selective amplifying device.
IPC: H03H9/54
Filed: 1966-12-07
Abstract: 1163604 Semi-conductor devices COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT 7 Dec 1966 [17 Dec 1965 11 Oct 1966] 54832/66 Headings H3U UAB UN U22 U30 U28 U31 and U26Y A frequency selective amplifier comprises an element with semi-conductive and Piezo-electric properties having a definite natural frequency for a prescribed mode of elastic vibration, input means for periodically injecting charge carriers into the element in response to a control signal, a voltage source creating'an electric field in the element sufficient to accelerate the injected carriers to at least the velocity of propagation of the elastic vibration, and an output means coupled to the body. When the input signal has a component of frequency corresponding to the natural frequency of the element an amplified version of they signal appears at the output. In a typical device, Fig. 3, the element is an N-type gallium arsenide slab with its main faces normal to the 111 or 110 crystallographic axis. An injector consisting of nested base and emitter zones 28, 29 is formed by diffusion in one face and ohmic contact 36 of indium provided on the other, fine adjustment of the natural frequency of the system which is mainly determined by the thickness of the slab being effected by varying the mass of the contact. The accelerating voltage is applied between contact 36 and the emitter and the output voltage derived through annular ceramic capacitors 35, 36 indium soldered to opposite faces of the slab. In another device comprising a cadmium sulphide body carrier injection is effected by directing modulated light from a gallium arsenide source on to the body. In this case the accelerating field is applied between ohmic contacts. Several such devices with different resonant frequencies may be mounted in a hexagonal formation on the insulating base of a sealed housing, light from a common source being directed on to them via a diverging lens. In a modified structure in which the output is derived through a single capacitor one of its electrodes also constitutes one of the contacts through which accelerating voltage is applied. Carrier injection may also be effected by means of an electron gun or a photocathode attached to the semi-conductor body.

Title: Motor control circuit for a camera
IPC: G03B17/42
Filed: 1974-12-28
Abstract: 1498188 Control of D.C. motors KIONSHIROKO PHOTO INDUSTRY CO Ltd 28 Dec 1974 [28 Dec 1973] 55292/74 Heading H2J A control circuit for a D.C. motor M, which drives the shutter and the film wind mechanism of a camera operable to take a succession of photographs, comprises timing means to provide a time interval between successive film exposures and consisting of an adjustable resistor VR1, low value resistor R1, capacitor C<SP>1</SP>1 and a momentarily-operable switch SW1 to discharge the capacitor, and a switch RL1-1 operable by operation of a shutter release switch SW5, whereby the closed and open conditions of the switch SW5 respectively cause the switch RL1-1 to open to render the timing means operative and to close to render the timing means inoperative. With switches SW3, SW4 moved from their single photograph contact positions S1, S2 to their sucessive photographs contact positions C1, C2, the following sequence of operations occurs, after closure of a switch SW9 has caused capacitor C<SP>1</SP>1 to charge through members RL1-1, R1 of which switch RL1-1 is the normally-closed contacts of a relay RL1: (1) Closure of switch SW5 energizes relay RL1 to open switch RL1-1. Also a relay RL2 is energized through switches SW2, SW10, SW5 and transisitor TR1 made conductive by circuit TC1 when C<SP>1</SP>l is charged. (2) Relay contacts RL2-1 change over to energize motor M, which operates and releases the shutter. (3) During film exposure a diaphragm mechanism opens the switch SW10 to de-energize relay RL2 and change over contacts RL2-1 to stop and brake the motor. (4) After exposure switch SW10 is closed and switch SW2 changes to contact B to energize relay RL2 through transistor TR2 made conductive via members SW4, R5. (5) Contacts RL2-1 change over to energize the motor to wind the film. (6) At the end of winding, switch SW1 is momentarily closed to discharge capacitor C<SP>1</SP>l and so turn off transistor TR1, thereby de-energizing relay RL2 when switch SW2 changes back to contact A and hence stopping the motor. (7) After a time interval determined by setting of VR1, capacitor C<SP>1</SP>l recharges to switch on transistor TR1 and, if switch SW5 is still closed, operations (1) to (6) are repeated. If switch SW5 is opened during successive photography, the motor will be stopped in a state in which the film is wound up and switch RL1-1 will close to allow immediate recharge of capacitor C<SP>1</SP>l and so enable a further photograph to be taken immediately switch SW5 is closed.

Abstract: 1,109,403. Radio navigation. DECCA Ltd. 1 Nov., 1966 [1 Aug., 1965], No. 55998/67. Divided out of 1,190,402. Heading H4D. [Also in Division G1] Navigational apparatus for a mobile craft comprises a receiver for a radio position fixing system of the kind in which equipment on the craft determines its range and bearing from a selected ground station, a computer to which the range and bearing information is fed, data storage means, storing information representative of the positions of a plurality of radio stations of the position fixing system, a selector switch arranged to feed information about the position of the selected ground station to the computer, the computer providing input signals to a chart recorder for continuously marking the position of the craft on a chart in accordance with the inputs received from the radio receiver and the data storage means the computer being operative to determine the distance between the position of the craft, as determined by the receiver using one ground station and the next selected ground station so that when the distance to the station being used exceeds that to the next selected station the receiver may be returned, manually or automatically, to the next station. The receiver may be automatically tuned to the most appropriate, usually the nearest, ground station. In this case the position of the craft determined by a VOR/DME system is compared in a selector with the positions of the various stations stored in the data storage means to select the appropriate ground station. The output from the selector drives the selector switch to the setting corresponding to the selected station, the receiver then being automatically tuned to this station and the chart recorder will indicate the craft position using information from the selected station. If two receivers are provided one may be tuned to the nearest ground station for position fixing and the other tuned to the next station to be used. In this ease the computer may switch over automatically when the range to the next station becomes less than that from the station in use. Whilst changeover from one ground station to another is taking place the computer may feed the chart recorder with signals representing the last received heading and speed values so that correction of the indicated craft position on the chart after such period of changeover will be minimized.

In a microwave tube, band edge oscillations in a slow wave structure, which includes an array of coupled, non-helical conductive parts, are reduced by including at either end of the structure an impedance matching transition portion 12, 13 of the same general form as the main structure, but of progressively modified geometry, such that the band edge frequency progressively varies from that of the main structure to a value, at the outer end of the transition portion, which is substantially, e.g. at least 5%, outside that of the main structure, whereby the band edges are heavily loaded by the input or output load resistance. Details of suitable geometrical parameters by variation of which tapering of either or both of the low or high-frequency band edges may be produced are provided for the following structures: a stub-supported vane circuit (Figs. 5 and 6, not shown); helix-coupled vane or bar circuits (Figs. 7 and 8, not shown); a stub-supported meander line capacitively loaded by a ridge projecting from a back support wall of the structure towards the meandering element, through which element coolant may be circulated (Fig. 9, not shown); an interdigital line (Fig. 14a, not shown), which may be stub-supported (Fig. 14b, not shown); a reactively loaded interdigital line, providing alternate series and shunt interaction with an electron beam, and consisting of an interdigitated structure the fingers of which are bifurcated to form slots (Fig. 11, not shown); strapped bar structures (Figs. 12 and 15, not shown); and a disc-loaded waveguide, in which the tapering is produced either by an increase in diameter of the waveguide, or by an increased spacing between the discs. Preferably, each transition region is tapered to a different band edge frequency, and if the circuit is provided with a sever (Fig. 3, not shown) each separate section of the slow wave structure is provided with end transition region tapering to different band edge frequencies. The transition portions may be disposed-e.g. in an output waveguide section-such that they do not interact with the electron beam.
