Title: Improvements in and relating to electron beam scanning arrangements
Inventor: MARTIN JEAN-PAUL
IPC: H01J37/28
Filed: 1982-06-15
Abstract: To compare adjacent and nominally identical patterns, e.g. on an integrated circuit mask, specimen 16 is positioned to be impinged by an electron beam 20, directed by control unit 24 to one of the patterns, by beam control coil 14 and/or a specimen motor unit 56, and a time base unit 46 causes the beam to perform a raster scan of that particular pattern. The resultant electrical signals from secondary electron detector 22 are stored in a memory 32. The beam 20 is then switched to another of the patterns on the specimen 16 and a second raster scan is performed. This time the control unit 24 and a switch 28 direct the signals via a subtracting unit 36 whose other input is synchronously fed from the memory 32. Any difference between two patterns, appears via a line 42 on a CRT. Other methods of comparison disclosed include a multiplexing arrangement which avoids the need for the memory 32. <IMAGE>

Patent GB-2113592-A (GB)
Title: Laser machining apparatus
Inventor: JONES GODFREY DENTON
IPC: B23K26/08
Filed: 1983-01-13
Abstract: A laser machining apparatus (1) for burning holes in a workpiece has an objective lens (20) which is movable by means of motor-driven carriages 28, 30 in a plane generally perpendicular to the lens axis to enable the laser beam to be moved and focussed at different surface locations on the workpiece (14). This enables clusters of holes to be machined in the workpiece surface without the necessity of moving the workpiece except, perhaps, for horizontal movement which is normally a rotational indexing of the workpiece, the laser beam being horizontally directed. Detection of burn- through of the beam is effected by an optoelectronic detector circuit which monitors the light intensity transmitted from the workpiece surface during burning of a hole by the laser, the light being transmitted back along the laser beam path through a mirror and filter system (18, 38, 44) to the detector circuit. Once burn-through is effected the fall in light intensity is detected by the circuit which triggers movement of either the beam or workpiece or both. <IMAGE>

Title: Electroluminescent device
Inventor: REEHAL HARICHARAN SINGH
IPC: H01L33/00
Filed: 1983-06-06
Abstract: An electroluminescent device (10) comprises an electroluminescent layer (11) together with a p-type silicon layer (13) and an n-type silicon layer (14). The layers (11, 13, 14) constitute a heterojunction or transistor-like structure which limits the total device current during operation. This avoids current runaway experienced in prior art devices, and has been found to extend operating life. The electroluminescent layer may be in contact with a transition metal oxide layer to provide self-healing of pinholes. The electroluminescent device may include additional p-type and n-type silicon layers to provide a degree of current control. The p-type silicon layer may be connected to an ohmic contact for control of device current. The silicon layers (13, 14) are either crystalline or amorphous. <IMAGE>

Title: A method of soldering together two surfaces
Inventor: BATES MURREY
IPC: B23K1/20
Filed: 1983-07-30
Abstract: A method of soldering together two identical aluminium components includes degreasing the components and masking all but the surfaces to be soldered with tape 7. One component is then grit- blasted to give a roughened surface. Copper is sprayed on to the component to give a layer 8 and then solder is sprayed on, giving a second layer 9. The solder will adhere to the copper layer 8, whereas it will not adhere to aluminium. Flux is then applied, with additional solder, and the other component, to which identical processes have been applied, is placed adjacent the first with soldered surfaces in contact. The components are heated, the solder becomes molten and when allowed to cool, forms a bond. <IMAGE>

Title: Method and apparatus for making screen panels
Inventor: BENSON HENRY EDWIN
IPC: B29C65/20
Filed: 1983-08-12
Abstract: Apparatus for making plastic screen panels, and especially abrasion-resistant mining screens, includes a large rotary screen drum member on which an extruded, profiled cross-section screen surface-forming wire is helically wound at a pitch which will produce the desired screen slot width. Immediately adjacent the drum member is a rod-positioning mechanism from which a plurality of screen panel support rods are sequentially fed from a stack and welded to the wires on the drum surface in a direction parallel to the drum axis and transverse to the surface wires. The welding is done with a double-edged heater bar which is temporarily placed in contact with the rod and drum before the rod is forced against the drum. The screen drum is indexed after each support rod is attached to it by an angular amount sufficient to provide the desired spacing on the finished panel. After all the rods are attached to the wire-covered drum, the wires are severed along a line parallel to the drum axis and the now-finished panel is removed and used as is or preferably is cut to form several smaller panels.

Title: Oxygen cells
Inventor: PETRUCCI MICHELE
IPC: G01N27/416
Filed: 1984-10-24
Abstract: In a solid electrolyte oxygen cell in which the unknown oxygen partial pressure of a fluid medium is ascertained by measuring the emf between two electrodes 6 and 8 of the concen- cell, oxygen at a known partial pressure is produced as a reference by means of a substance 3 which reacts with the oxygen to produce compounds which are easily removed from the reaction area within a chamber 1. In this way, the problem of polarization of the cell is eliminated, for example, and so its useful life is considerably extended and the signal continues to remain extremely accurate over the long term. Substance 3 may be carbon or sulphur which produces gaseous products on reaction with the oxygen. Alternatively it may be lead or tin which produces products which slag easily and which substance is liquid at the temperature of the fluid medium. <IMAGE>
