Title: Field-emission cathode
Inventor: WINDSOR EDWARD ERIC
IPC: H01J1/304
Filed: 1964-01-03
Abstract: <PICT:1028351/C6-C7/1> <PICT:1028351/C6-C7/2> In the production of a field-emission cathode, one end of a thin rod 3 cut from a zone-melted bar of crystalline lanthanum hexaboride is supported from a rhenium loop 4 and is treated in an electrolytic bath to obtain a fine polished needle-like point by immersing the end of the rod as anode into a capillary tube having an annular platinum cap cathode 11 and upwardly through which is fed sulphuric acid.  Twenty pulses of square wave D.C. potential are applied directly, the current passed changing progressively from the form (b) to (c) to (d) as shown in Fig.6, E indicating an etching or shaping action and P a polishing effect, and then three pulses are applied successively from each of three condensers C3, C2, C1 of 8, 4, 2 m F to effect final polishing. By selecting the acid flow rate a waist may be produced adjacent the cathode and by withdrawing the rod a desired shape may be formed. For a needle point of small cone angle a waist is formed near the end of a thin needle until the weight of the depending portion causes fracture and the broken end is then polished. A bar with more than one point may be formed by first cutting the end longitudinally e.g. with two orthogonal cuts.  An initial cleaning of the bar may be effected by passing a heating current through the loop 4.ALSO:In the production of a field-emission cathode, a bar cut from a sintered disc of lanthanum hexaboride is zone-melted.  A thin rod is then cut from the bar and one end treated in an electrolytic etching bath to form a fine needle-like point.  A plurality of points (Fig. 8, not shown) may be obtained by first cutting the end into a plurality of parts (Fig. 7, not shown). The rod diameter may be 0.1 mm. and the tip diameter may be 1 micron.ALSO:In the production of a field-emission cathode, a bar cut from a sintered disc of lanthanum hexaboride is zone-melted.

They may be used for dyeing and printing leather, silk, wool, animalized cellulose, casein fibres and superpolyamides or superpolyurethanes.  R1 may be further substituted, especially by atoms or groups incapable of salt formation, e.g. chlorine, bromide, methyl, ethyl or methoxy. R3 preferably has the two sulphonic acid groups attached to different rings.  Diazotization may be effected in the presence of alcohol or acetic acid or with nitrosylsulphuric acid, and coupling may take place in the presence of alcohol or pyridine. In the examples: (1) diazotized 41 - tert. amyl - 2 - amino - diphenyl ether and its 4-chloro derivative are coupled with 1-naphthol-3 : 6-disulphonic acid and with 2-naphthol - 6 : 8 - disulphonic acid; (2) diazotized 41 - tert. amyl - 4 - amino - diphenyl ether is coupled with 1-naphthol-3 : 6-disulphonic acid; (3) diazotized 41-tert. amyl-2-amino-diphenyl ether is coupled with 2-naphthol-3 : 6-disulphonic acid; and (4) diazotized 41 - (1 : 1 : 3 : 3 - tetramethylbutyl)-2-amino-diphenyl ether is coupled with 1-naphthol-3 : 6-disulphonic acid.

Title: Automatic gain control circuitry
IPC: G01H1/00
Filed: 1969-01-07
Abstract: 1,248,161. Volume compression; transistor oscillator circuits. I.R.D. MECHANALYSIS Inc. 7 Jan., 1969 [11 Jan., 1968], No. 964/69. Headings H3T and H4R. [Also in Division G1] In a sensing apparatus, e.g. vibration pick-up or spacing detector, the change in sensitivity resulting from changes of instantaneous gap between a stationary pick-up inductor 30 and a metallic object is compensated for by a F.E.T. 120 by varying its dynamic resistance. As shown, a pick-up coil 30 is included in the tank circuit of a Collpitts oscillator 70, the amplitude of the output oscillations of which varies with the spacing of the metallic object from the coil 30. The oscillator output is rectified by a rectifier 100 producing a sinusoidal D.C. voltage when the metallic object vibrates. The resultant voltage is applied across the drain and gate electrodes of the F.E.T 120, the voltage applied to the gate electrode being proportional to the average of this resultant voltage produced by capacitor 16. As the sensitivity of the apparatus increases or decreases, due to proximity of the object, the output of the F.E.T. decreases or increases respectively to maintain the R.M.S. amplitude of the resultant voltage constant. This voltage may then be amplified as shown and the vibrational frequency of the object determined. The apparatus may be calibrated by varying potentiometers 94, 126, 134. A resistor 122, connecting the source electrode of F.E.T. 120 to ground, provides temperature compensation for sensitivity between 32‹ and 150‹ F. At higher temperatures sensitivity is maintained constant by providing a negative temperature coefficient thermistor 48 in series with coil 30, a resistor 54 shunting thermistor 48 to provide the thermistor with a linear temperature/resistance characteristic. The output of the oscillator may be temperature compensated by providing a further thermistor 90 in the base bias of the oscillator. Coil 30, thermistor 48 and resistor 54 may be provided in a tubular probe, Fig. 2 (not shown), which may be used to determine the vibrational frequency of a shaft rotating in a bearing, Fig. 1 (not shown). Specification 1,248,162 is referred to.

IPC: G09G3/00
Abstract: 535. Scott, W. R. June 20. Moving and changing apparatus.-Relates to advertising-apparatus, in which the various letters or the like on panels c, Fig. 3, are alternately exposed to and masked from a source of light g by shutters i actuated by cams m, Figs. 2 and 3, on rotatable shafts n, and consists of means, such as an escapement, for giving an intermittent movement of rotation to the shafts, and means, such as springs and auxiliary cams, for putting the shafts out of action. The colour of the illumination may be varied by rotary screens, surrounding the lamps &c., driven by chains with or without an escapement for effecting a step-by-step rotation. The shutters i, provided with snap-springs o and connected in pairs. by rods l, are operated intermittently by cam-projections m on the rotatable tubes n, and projections 4 on rods l. The tubes n are selectively rotated by a driving- mechanism, with which they are connected by two pins, or a slotted member on each of the intermeshing gear-wheels p, q, engaging a pin or projection on the corresponding shaft n. A bevel-wheel on the gear-wheel p is driven by bevel-gearing r, u and a shaft v, rotated by a clock-work or other motor. A step-by-step movement is effected by a two-armed lever w, Fig. 4, on the end of the shaft v, which engages a tooth in the lower of a pair of rotary wheels 1, 2, passes through to a tooth of the next of the two wheels, and then escapes. The cams m on any rod n are put out of operation against the action of springs by one of the cams 5 on a driven axle 6. Each cam engages a rod 7 and directly operates the upper rods n, and operates the lower rods n through a lever 9, Figs. 4 and 5, so as to move them in the opposite direction to that of the upper rods. Intermittent movement of the cams may be effected by a projection 11 on the rotary shaft 12 periodically engaging cams 13 on a wheel, which is connected to the cams 5 or their shafts. According to the Provisional Specification, the backs of the shutters i may be made reflecting.

Title: Formation of pattern
Inventor: FUJIMURA SHUZO
IPC: H01L21/265
Filed: 1988-01-05
Abstract: PURPOSE:To remove a resist by an ashing operation after an ion implantation operation without leaving a residual substance (at a level of visual observation) by a method wherein the resist containing a normal-chain aliphatic polymer, instead of a resist containing a novolak chain, is used as a resist mask for ion implantation use. CONSTITUTION:A resist layer whose thickness is thicker than that of a projection range of implanted ions and which contains a normal-chain aliphatic polymer is used as a resist mask pattern for an ion implantation operation. Alternatively, a two-layer resist layer composed of an upper-layer resist layer containing a normal-chain aliphatic polymer and a lower-layer resist layer containing a novolak resin is used after its thickness has been made thicker than that of a projection range of implanted ions. For example, even PMMA which is used as a resist for far ultraviolet rays and an electron beam can be used as a photoresist if an appropriate photosensitizer is added and mixed or the like. By this setup, even the normal-chain aliphatic polymer which is not the photoresist can have photosensitivity.
