[Also in Divisions B3 and C7] A method of making an electron-permeable window for an electronic recording tube comprises evaporating or sputtering a layer 2 of a metal such as nickel on a glass support 1 and exposing the completed layer to air for several minutes; evaporating a metal 4 such as gold, silver or platinum on the layer 2; depositing a further metal layer 4, e.g. of nickel by a plating process; and stripping off the layers 3 and 4 to form the window. Any pin-holes in the window may be sealed by coating the interior surfaces of the window with a silicone resin or an epoxy resin and applying suction to the opposite surface; the resin may be removed by a solvent, or a thin layer may be allowed to remain. This layer may be coated with an evaporated layer of aluminium to prevent charge from accumulating on the dielectric. As shown in Fig. 2, an insulating layer 5 may be formed on the layer 4 by a photo-resist process followed by further nickel plating to produce the support layer 6, the layer 5 then being moved. The window may be arranged between two support members (8 and 10, Fig. 3 not shown) which are bonded together and to the envelope by binder layers (9 and 12).

Title: Automatic polarization analysing device
IPC: G01N21/21
Filed: 1973-12-18
Abstract: 1459410 Photo-electric polarimeters NIPPON KOGAKU KK 18 Dec 1973 [22 Dec 1972] 58492/73 Heading G1A In a known polarimeter an optical element is rotated by a servosystem in response to a photoelectric error signal until a null position is reached, the null position being indicated to represent a polarization property of the sample under test. The servosystem has a dead zone in the vicinity of the null position (to prevent mechanical oscillation of the servo), and hence the null position cannot be accurately found; to overcome this, the invention uses the electric error signal existing when the dead zone is reached to correct the indication of the null position. The known polarimeter is shown in Fig, 1 within broken line 18. The optical elements comprise source 1, collimator 2, filter 3, rotatable polarizer 4, quarter wave plate Q, sample 5, rotatable half wave plate H, modulator 6, quarter wave plate 7, modulator 6', analyser 8, condenser 9, and photocell 10. Two phase displaced square waves drive the modulators 6, 6', and also drive synchronous rectifiers 13, 13'. The rectifier outputs drive servos 15, 15' to move elements 4 and H to a null position, and potentiometers 16, 16' coupled to the servos drive indicator circuits 17, 17' to indicate the null positions of the two elements and hence to indicate two polarization properties (azimuth and phase) of the sample. To avoid inaccuracy due to the dead zone of the servos, the invention provides two D.C. amplifiers 19, 19', and corresponding remaining angle indicator circuits 20, 20' which allow the  error signal components to be displayed when the dead zone is reached. The remaining angles are then simply added to the main indications at 17, 17'. Alternatively the display at 17, 17' may be auto-  matically corrected by the error signal. The two squarewave signals used may be of the same or different frequencies. In another embodiment, Fig. 5 (not shown), the squarewaves are modulated with higher frequencies, and the resulting modulation is detected in the photo-electric cell signal and is used to correct the output for any loss of light intensity, e.g. due to lamp aging, dirt &c.

Title: Process for the fabrication of light-emitting semiconductor diodes

Filed: 1969-12-01
Abstract: 1300067 Electroluminescence TEXAS INSTRUMENTS Inc 1 Dec 1969 [23 Jan 1969] 58518/69 Heading C4S [Also in Division H1] The invention makes use of the high rate of diffusion of zinc along the interface between an A<SP>III</SP>B<SP>V</SP> body containing phosphorus and a masking layer of (phosphorus-doped) silicon oxide. A somewhat less high zinc diffusion rate prevails with non-phosphidic A<SP>III</SP>B<SP>V</SP> compounds which may also be used. In a particular embodiment an n-type gallium arsenophosphide body 11 is provided with an apertured silicon nitride mask 12 and the assembly then coated with a layer 13 of phosphorus-doped silicon oxide which lies on the nitride mask and directly on the semiconductor where the nitride mask is apertured. An annular portion 14 of the oxide is removed contiguous with the edge of the aperture in the nitride and the structure is then heated in an atmosphere containing zinc. The nitride-semiconductor interface does not favour lateral zinc diffusion which however occurs under the oxide so that in the structure shown the deeper part of the pn-junction 16 is outlined by the nitride mask and the shallower less heavily doped part is formed as a result of lateral diffusion under the oxide. Both masking layers are removed and the body recoated with an oxide layer in which an annular aperture is formed so that an evaporated zinc-gold electrode may be provided on the thicker part of the p-type region. (Gold-antimony may be used to contact the n-type body.) The resultant diode emits light of high intensity from the shallow part of the junction through the overlying oxide. A similar embodiment (Figs. 6-10, not shown), utilizes a rectangular slot in the oxide mask to provide a rectangular p-type region of tapered thickness with a deep highly doped portion at one edge at the position of the diffusion slot.
