Title: A magnetic field detector
Inventor: MALMHAELL ROGER
IPC: G01R33/02
Filed: 1990-12-24
Abstract: A magnetic field detecting device, particularly for detecting the earth's magnetic field, includes one or more amorphous or microcrystalline magnetic fibres having two bistable magnetization states and surrounded by at least one measuring coil (103). The measuring coil is supplied with a periodically changing control signal (101a) which is superposed with a detected signal (103a) contingent on the sensed magnetic field. After detection at (121) signals (123a, 1 23b) obtained therefrom are caused to control a flip-flop (122) which influences the working direction of an integrator (101), the output signal of which forms a performance signal in addition to forming said control signal. The performance signal (101c, 106a) is processed in a microprocessor (107), to which a control signal (122b) is also delivered from the flip-flop, and is able to restart the circuit when a control signal fails to appear. in order to determine the directional sense of the field a pair of detecting devices are provided extending at right angles to each other. <IMAGE>

Title: Method for forming field oxide layer of semiconductor device
Inventor: PAEK WEON-SIK
IPC: H01L21/316
Filed: 1991-03-20
Abstract: A method for forming a field oxide layer (36) of a highly integrated semiconductor device comprises the steps of depositing a pad oxide layer (31) and a nitride layer (33) over a substrate (30), removing the nitride layer (33) over a field region, forming spacers (34) on the side walls of the remaining nitride layer, doping an impurity into the field region using the spacers (34) as a mask, thermally oxidizing the substrate (30) exposed in the field region, growing the field oxide layer (36). and planarizing the upper portion of the field oxide layer (36) by an etchback process, thereby reducing the step coverage problem of the field oxide layer (36). Thus, the size of birds beak and stress can be reduced at the edges of the field region. The heavily doped channel stop (35) layer is formed only in the middle section of the field region. thereby preventing the lowering of the breakdown voltage and punch-through. <IMAGE>

Patent GB-923742-A (GB)
IPC: F01D17/02
Abstract: 923,742. Gauging apparatus. SOLEX (GAUGES) Ltd. May 10, 1961 [May 18, 1960], No. 17535/60. Class 106 (2). [Also in Group XXIX] The cross - sectional area available for fluid flow in a test component 8 (Fig. 1), for example, through the vanes of a jet engine, is measured by adjusting the effective area of a variable orifice 7 until the total outflow of air through orifices 6 and 7 is such that the pressure in the chamber 4, supplied with a steady airflow at the speed of sound via the inlet 3, attains a value indicated by a datum level of the manometer 40. The longitudinal setting of the conical member 11 used for varying the effective area of the orifice 7 is read on scale 12 and compared with the setting for a standard component 8. A scale 13 adjacent the manometer may be calibrated to indicate the approximate range of adjustment necessary for a given departure of the manometer level from the datum. To minimize the effect of fluctuations in the air-supply pressure, the upper end of the manometer tube may be connected to a separate chamber, also pressurized by the air supply. The variable aperture may be formed by a slit 20 and a slide 21 adjustable by means of an hydraulic system, as shown in Fig. 6, or by means of an electric servomotor, in response to out-of-balance signals, with reference to the manometer datum level, provided by a photo-cell cooperating with an illuminated slit adjacent the manometer. Alternatively, a differential pressure-sensitive diaphragm arrangement may be used instead of, or in addition to, the manometer, and may be provided with electrical contacts, or the diaphragm itself may form one plate of a variable condenser, for giving out-of-balance signals to a servo-mechanism and/or to a cathode-ray tube for visual observation. The servo-mechanism may be used to control a machining operation on the component under test. Deflection of the diaphragm may also be indicated by mechanical or pneumatic means. Non-linearity between the movement of slide 21 and the resulting variation of pressure may be compensated by movement of the scale 25 (Fig. 5), caused by a cam-lever 23 co-operating in the cam 22 of predetermined shape. For measuring large orifices an obturating block may be provided and supported within the orifice 6 to give a known reduction of cross-section. If the test component has a plurality of orifices, the opening in the chamber 4 may comprise a number of correspondingly positioned valves which can be selectively opened by manual operation. The algebraic sum of errors for a batch of components is given by arranging the variable orifice control to drive a clutch on the return movement to the nominal position and thereby operate an indicator.

Title: Variable section vane
Inventor: LLOYD JASON NEIL
IPC: F02K1/00
Filed: 1993-03-13
Abstract: A deflection vane for use, for example, in a cascade nozzle in the gas stream of a vectoring lift nozzle of a VTOL aircraft has a transverse section variable according to the position of the vane. The vane has flow surfaces 8 and 9 formed of flexible material which bear against an internal cam 14 of elliptical section. The cam is fixed so that as the vane is turned about its longitudinal axis to deflect the gas stream it changes shape. The arrangement is such that in a cascade array of parallel vanes the throat gap Y between adjacent vanes remains constant thereby avoiding throttling the gas stream.

Abstract: A fluid density sensor uses a buoy 31 on a cranked body 30 which effectively pivots about an axis 35 and is mass balanced in a fluid of similar density to that to be measured, but has a large volume moment. A displacement transducer 37, 38 is coupled in a feedback circuit to a force coil 36 acting on a pair of opposed pole magnets 33, 34 on the body 30 to restore the body to its equilibrium position as fluid density changes, the force required giving a measure of the fluid density. Three sensors together on non-parallel axes are used in a densitometer that is independent of spatial orientation, and can be used in an oilwell borehole logging tool. As shown, the displacement sensor is of inductive type, but other forms are envisaged. <IMAGE>
