Title: Process for producing a metal coating on a ceramic body
IPC: C04B41/89
Filed: 1963-12-06
Abstract: In a process of metallizing an unglazed ceramic surface a powder mixture of a metal such as Fe, Ni, Mo, W, Mn and a silicate consisting of or including magnesium silicate, iron silicate or manganese silicate is applied to the ceramic and sintered.  The silicate should not release metal ions during sintering and should have a melting temperature just above the temperature to which the metallized coating is subjected to during subsequent soldering or further coating with nickel.  The sintering is effected at 1250-1350 DEG C. in a weak oxidizing atmosphere such as moist cracked ammonia. The metallizing powder should contain at least 20% by weight silicate which in addition to manganese silicate may be a compound of any one of the systems MnO-Al2O3-SiO2, Fe-O-Al2O3-SiO2, MgO-Al2O3-SiO2.ALSO:In a process of metallizing an unglazed ceramic surface a powder mixture of a metal such as Fe, Ni, Mo, W, Mn and a silicate consisting of or including magnesium silicate, iron silicate or manganese silicate is applied to the ceramic and sintered.

Title: Improvements in and relating to methods of masking
Inventor: KLEIN THOMAS
IPC: H01L21/00
Filed: 1963-12-13
Abstract: 1,069,467. Semi-conductor devices. MULLARD Ltd. Dec. 13, 1963, No. 49356/63. Heading H1K. In a method of masking a semi-conductor body, the surface of the body exposed through a window in a first oxide layer used as a diffusion mask is re-covered with a thinner layer of oxide in which a window having a smaller area than the window in the first layer but extending to the same boundary in one lateral direction, is formed by etching the oxide layers over a lateral area which overlaps the first layer in the said lateral direction. As shown, an N-type silicon body 1 doped with phosphorus is heated in wet oxygen to form an oxide layer 2. A window 4 is etched in this layer, using a photolithographic technique, and boron is diffused into the body to form a P-type region extending to the junction 5. The body is cleaned in concentrated nitric acid and washed, and the surface of the body is then re-oxidized to form a thinner oxide layer 3 and to slightly increase the thickness of the layer 2. The oxide layers are then etched over an area which overlaps layer 2 so that portions 7 are removed from layer 2 and a window 6 is produced in the thinner layer 3 extending to the same lateral boundary as window 4. Phosphorus is diffused through window 6 to form an N-type region extending to junction 8. During this second diffusion the junction 5 moves further into the body. The body may then be ground and etched, leads may be attached to the three regions, and the resulting transistor may be encapsulated.

As shown, blades 13 are mounted on a support 5 reciprocable by main and auxiliary hydraulic cylinders 3 or 4 respectively. The blades can be moved by cylinders 12 to vary the interblade spacing to suit different sections 50. A spacer 15 and lock bolts 16 maintain the spacing. Supports 45 for bracing the section against bulking during shearing are mounted on a beam 40 suspended from the frame 2 by cylinders 40, 41. The spacing between the members 45 is variable by means of hydraulic cylinders 47. Further supports 26 for clamping the outer faces of the flanges 51 are slidably mounted on plates 22. The spacing between plates 22 can be adjusted by means of drive screws 23 operated simultaneously by means of a handwheel 35. The spacing between the supports 26 is variable by means of hydraulic cylinders 27. The blades 13 are directly mounted on a frame 9 pivoted to the support 5 at 7 and supported by hydraulic cylinders 8. In operation; the planes 22 and supports 26 are adjusted to allow a section to be cut to be placed between the clamping portions 32 of the supports 26. The blade spacing is adjusted and a spacer 15 inserted. The supports 45 are moved towards each to allow a section to be fed in to the shear. The supports 26 are moved in to clamp the section with the flanges 51 resting on shoulders 31. The supports 45 are then moved apart to clamp them against the inner faces of flanges 51 and the lower face of the web 52. The cylinders 8 are operated to make the cutting edges of the blades horizontal and the cylinders 3 or 4 are lowered at low pressure to start the cut. The blades are then raised by cylinders 4 and given a rake angle α by cylinders 8, Fig. 1, the frame 9 being braced against the support 5 to relieve the hinge 7 and cylinders 8 of shearing load. The cylinders 3 are then actuated at high pressure to shear the web 52 from the flanges 51 of section. The supports 45 are lowered by the action of the blades against the damping action of cylinders 40, 41. The hydraulic cylinders 3 and 4 may be replaced by a crank and eccentric drive (60), Fig. 5 (not shown).

Clock pulses are gated to a counter while a light beam scans from a zero position on a graph or diagram to a line on the graph or diagram. By taking a series of parallel scans, the area under the line is accumulated. In Fig. 1, a circular graph is rotated once on a table 19 while a rotary member 4 geared to the table 19 and carrying six objectives, i.e. lenses 11, rotates 400 times about a parallel axis so that the objectives scan the diagram 2400 times along respective shallow curves which have a radius of curvature equal to the length of the pivoted pen which originally recorded the diagram. The curves lie approximately radially on the diagram. Light from a source 8 is reflected 9 through the objective 11 and a curved index slit (21) on to the diagram and reflected back through the objective 11, a filter 14 to select the appropriately coloured lines on the diagram, diaphragms 15, 17 and an optical condenser 16 to a photomultiplier 18. The rotary member 4 carries mutually displaced scales at 3 which are sensed photo-electrically as the member 4 rotates to provide clock pulses, which are gated via dividers to a counter under control of the photo-multiplier 18, the clock pulses being cut off as the beam reaches the leading and trailing edges of the line alternately to compensate for line thickness or lines with closely spaced oscillations. The counter output is displayed, and printed, e.g. on the diagram itself. A scan counter controlled by the photomultiplier 18 counts a preset number of scans and prevents utilization of data from subsequent scans, so with choice of the starting position of the sensing, any fraction of the diagram may be scanned only. Figs. 6, 7 (not shown) show the mechanical modifications necessary for scanning linear diagrams along straight and curved paths.
