Abstract: SPECIFICATION                TO ALL WHOM IT MAY CONCERN:              BE IT KNOWN, that We, TIMOTHY WILLIAM JANES, resident of 83 Columbia Drive, Worcester, Worcestershire, England, and JOHN CHARLES WHITE, resident of 70 Tennyson Drive, Malvern, Worcestershire, England, have invented certain new and useful improvements in A METHOD FOR PRODUCING A VERTICAL CHANNEL TRANSISTOR and we do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same:     ABSTRACT OF THE DISCLOSURE     A steep-walled mesa is defined by ion beam, plasma or orientation dependent etch, and has a thick insulating layer over its uppermost surface.  The material of the mesa is undercut to leave the insulating layer overhanging.  Further insulating material is then formed thinly over the exposed mesa material and conductive material deposited giving good coverage of the insulated side-walls of the mesa.  Excess conductive material is removed by ion-beam milling, leaving a conductive material gate in the shadow of the cap-like insulating layer.            The orientation dependent etchant diazine catalysed ethylene diamine-pyrocatachol-water solution is used to form {111} crystal plane steep side-walled mesa from (110) surface oriented silicon, and aluminium metal conductive material deposited by chemical vapour deposition.

Abstract: Abstract of the Disclosure A door locking device for a microwave oven of the present invention has an engaging member arranged inwardly of the cooking chamber of the housing.          An arm is arranged at the rear surface side of a door and is biased clockwise by a spring, such that its horizontal state is kept by a stopper and the arm may be pivoted counterclockwise.  A locking eccentric cam having a notched engaging portion is mounted at the distal end of the arm so as to be pivotal about a shaft.  As the door is opened/closed, the notched engaging portion of the locking eccentric cam is engaged with the engaging member at the side of the housing to eccentrically pivot the locking eccentric cam, thereby locking/unlocking the door.

Abstract: ABSTRACT OF THE DISCLOSURE A novel ion exchange method is provided for the separation of hemoglobin AlC from other hemoglobin com-ponents in a sample of human blood.  According to the dis-closed method, the sample is lysed then used to impregnate a weak cation exchanger.  Two buffer solutions are then passed through the column in succession, the first having an alkali metal ion concentration of from about 0.02M to about 0.05M and the second having an alkali metal ion concentra-tion of from about 0.06M to about 0.11M.  The second eluate contains substantially all of the hemoglobin AlC and sub-stantially none of the other hemoglobin components in the original sample.  Analysis of the second eluate thus pro-vides a reliable indication of the long-term glucose level in the blood of a patient, and hence the patient's ability to regulate the quantity of glucose ingested.

Abstract: ABSTRACT OF THE DISCLOSURE           An atomizer is disclosed for atomizing liquid, having a disc clamped between two plate members, the disc being  provided with one or more slits which,  in combination with flat surfaces of peripheral regions of the plate members, constitute liquid atomizing nozzle ports having a tetragonal cross-section.  This arrangement permits easy formation of a plurality of nozzle ports and suppresses remarkably the tendency of clogging of the nozzle ports by foreign matter.   In addition, it is possible to form precise fine nozzle ports of a diameter which could not be attained by conventional equipment.          The tetragonal cross-section of the nozzle ports provides unique jetting characteristics for attaining good atomization of the liquid.

Abstract: Abstract of the Disclosure There is described a process and apparatus for flaring the end of a thermoplastic tube to form a flange thereon to provide a flanged adapter for joining sections of plastic pipes. An end portion of a tube of suitable thermoplastic resin is heated to soften it and is then placed in a flanged sleeve with the heated tube end projecting from the sleeve. flanged male plug is inserted into the heated end of the tube and the plug is pushed by means of a press into the tube to cause the flanged plug to flare the heated end of the tube outwardly through an obtuse angle against the flange of the sleeve so that a flange is formed on the tube.          A cylindrical member embraces the flanges of plug and sleeve and limits outer flow of the formed tube flange.  The tube is then cooled in situ in the press, is removed from the press after cooling and placed in a cold water tank for further cooling. After cooling, the flanged tube is constrained between top and bottom clamping disks and is reheated to about 160°F and then cooled at the rate of 10°F an hour until the flared tube is cooled to about 72°F.  Thereafter the tube is permitted to stand for a further 48 hours, or so, and is then machined.

Abstract: Abstract of the Disclosure Twin lead transmission lines are positioned in close coupling relationship to linearly polarized and planar arrays of antenna radiating elements to provide a self contained instantane-ous antenna test and measurement system.  Near field energy from the transmission lines is coupled to the transversely arranged antenna dipole elements to permit testing without degrading antenna performance.  Signals induced on the radiating elements are of uniform amplitude and linearly changing phase equivalent to those of a far field plane wave.  Various tests such as antenna failure and performance characteristic measurements, including gain, pattern and phase difference, can be made automatically.  A balanced power divider distributes RF power equally to the twin lead transmission lines and a system processor controls phase shifter scanning elements and analyzes the various output para-meters to provide the desired test and measurement information concerning the selected array of dipoles and components.
