Abstract: 1288237 Avalanche effect device NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP 19 Sept 1969 [21 Sept 1968] 46305/69 Heading H1K A semi-conductor device is constructed to exhibit a dual peak static field distribution on application of a direct voltage between two terminal electrodes. In operation, as a result of this bias or of a signal superimposed thereon or applied to a control electrode, avalanching occurs at one peak. In an oscillatory mode of operation avalanche carriers travel to the location of the second peak and there alter the space charge to cause further avalanching. The peaks are located at PN junctions between zones of opposite types contacting the respective terminal electrodes and the next innermost zones, and are less than 40 Á apart. The effective cross-sectional area of the current path through the device is less than that of a circle of 200 Á diameter. The device is typically of PNPN or PN1PN structure and may have, in addition to the terminal electrodes on the end zones, PN injecting control electrodes on one or more of the zones. A typical PN1PN structure with a current path cross-section corresponding to a diameter of 150 Á and zones thicknesses of 5, 5, 20, 3 and 2 Á respectively when mounted in a waveguide generates oscillations at 2.5 Ge/s.

Title: Control system for hydrofoil craft
IPC: B63B39/06
Filed: 1974-10-25
Abstract: 1458920 Automatic control of hydrofoil craft BOEING CO 25 Oct 1974 [10 April 1974] 46313/74 Heading G3R A hydrofoil craft has outer port and starboard control surfaces 32, 28 controlled by respective roll axis channels and inner port and starboard surfaces 34, 30 controlled by a further, common, roll axis channel. The invention is presented as being more reliable than control by a single channel. The complete system also includes forward control surfaces 18 and a rudder 12. All are retractable for surface travel. The system is described in block diagram form Figs. 3 and 4, (not shown). As shown, it comprises a height sensor 36, vertical accelerometers 35, 40, 42, a lateral accelerometer 38, a yaw rate gyro 46 and two identical vertical gyros 44, 45, both giving pitch and roll information. Their roll outputs are used separately and combined to provide the three channels of the invention. Alternatively, three separate vertical gyros may be used to provide the three roll channels. The system stabilizes the craft in pitch and roll, and a set  height is maintained. For turning, roll (bank) is applied in co-ordination with rudder movement. Each channel has a PD amplifier and the forward surface 18 (which is used for height control) is also stabilized by integrating the output of the vertical accelerometer 35 and a signal proportional to roll squared is applied to compensate for the loss of lift which occurs during roll. The rate of turning is limited by applying signals from the yaw rate gyro 46 and the lateral accelerometer 38 to the rudder servo.

Abstract: 1344319 Electrical measurements: self balancing bridge ROSE MOUNT ENG CO 14 Oct 1971 [19 Oct 1970] 47938/71 Headings G1N and G1U. A measurement system comprises a bridge network 32 into which a platinum resistance thermometer 24 is inductively coupled by a first transformer 20, a photo-sensitive resistor 48 of which the resistance is adjustable by light source 50 and which is coupled to the bridge by second transformer 45, a differential amplifier 36 responsive to the voltage across bridge output terminals 35, 37 to energize the light source so as to vary the resistor 48 to rebalance the bridge when the ratio of resistor 48 to that of thermometer 24 is restored to a predetermined value, and a D.C. amplifier connected to measure the voltage across resistor 48 and thereby its resistance and to provide an output signal indicative of the temperature of the resistance thermometer. The system is applied to measuring the temperature of a heated roll (10) Fig. 1 (not shown). Other applications include strain measurements on moving structures with a strain gauge in place of the thermometer 24. Capacitive coupling may be used instead of inductive coupling. The values of resistors 65 and 58 are chosen to provide linearization of the output signal with roll temperature thereby compensating for decreasing sensitivity with temperature of the resistance thermometer.

A housing for a radiation-activated semiconductor device has a hermetic seal established between an annular Al electrode 124 on the semi-conductor element 112 and a layer 129 of Ag disposed on the base member 116 of the housing, the seal being established by means of pressure exerted, e.g. by spring washers as shown, to hold the element 112 in good thermal and electrical contact with the base member 116. Radiation to control the element, e.g. provided by a GaAs laser, enters the housing through an aperture 76 extending through the base member 116 and in registry with the aperture in the Al electrode 124. The element 112 may be a Si thyristor as shown, or may be a transistor or diode. The Ag layer 129 may be plated with Au and brazed to the base member 116, or may be evaporated thereon and sintered, the latter procedure also being used to affix the Al electrode 124 to the Si body. The device carries an upper electrode comprising a plate 122 of Mo, W, Ta or alloys thereof soldered to the Si body and connected to a Cu lead 82. In order to enable the incident radiation to reach the central part of the Si body to produce turn-on, one of the base regions (62), Fig. 3 (not shown), may emerge at the lower face of the body (120) where it is surrounded by an annular emitter region (60). Alternatively the radiation may pass through the central area of the emitter region (260), Fig. 4 (not shown), to reach the base region (262).
