Patent EP-0285396-A2 (EP)
Inventor: TSUNEKAWA SHINICHI
IPC: H01J61/16
Filed: 1988-03-30
Abstract: A rare-gas arc lamp includes a pair of coil filaments (25, 27) disposed at the opposite ends of an elongated bulb (13) for increasing an area of a positive column produced between the coil filament pairs in a direction perpendicular to the elongated axis of the bulb, and a rare-gas mainly including xenon gas sealed in the bulb at a prescribed pressure selected from the range between 20 Torr and 200 Torr for reducing the evaporation of an electron emissive material coated on the coil filament pairs during operating. The combination of the coil filament pairs and the xenon gas sealed in the bulb at a prescribed pressure selected from the range between 20 Torr and 200 Torr may reduce visible changes in a luminance distribution of the lamp which occurs when the positive column fluctuates during operating.

Abstract: An optical disc reading apparatus is proposed having a reduced overall height and simplified structure. The disc drive motor (11) is mounted with its output shaft extending downward. A turntable (13) is fixed to the output shaft below the body of the motor. A disc carriage (15) is mounted so as to be movable only in a horizontal direction towards and away from the turntable, and a clamper (14) clamps a disc (16) once it has been conveyed by the disc carriage to the playing position on the turntable. A pickup (12) is mounted below the turntable on the side of a loaded disc opposite both the motor and turntable, and at least the objective lens (19) of the optical pickup is lowered away from the turntable when the disc is being loaded, to allow free movement of the disc towards the turntable.

Abstract: An internal combustion engine having a sleeve valve wherein the sleeve valve is the cylinder sleeve of a respective cylinder whereby a very simple reciprocation and oscillation of the sleeve valve may be effected by means of a rotary valve which controls the intake of a fuel-air mixture into the crankcase of the engine. By supplying the fuel-air mixture into the crankcase of the engine and providing each cylinder with transfer passages extending axially through the cylinder and radially adjacent cooling fins of such cylinders, it is possible to effect an isothermal compressing of a fuel-air mixture within the cylinder followed by that fuel mixture being adiabatically compressed by the movement of the respective piston towards the head. The use of a sleeve valve, particularly in association with rotary intake valves, provides for a very simple valving arrangement with a minimum of parts. Two such engines may be mounted in shaft-to-shaft relation and simultaneously drive coaxial shafts in opposite directions to provide for counter rotating propellers for an aircraft. The engine construction provides for a maximum power output with a minimum weight.

Abstract: A stripping composition for removing positive organic photoresist from a substrate, such as a semiconductor wafer, contains a triamine, such as diethylene triamine, and a nonpolar or polar organic solvent, such as N-methyl pyrrolidone. This composition will remove positive photoresist from semiconductor wafers, even after ion implantation into the wafers through the positive photo­resist. The wafers are immersed in the composition, for example, at a temperature of 110°C for five minutes, in an ultrasonic bath after heavy ion implantation doses through the photoresist, such as 1 x 10¹⁶ ions/cm², for complete removal of the photoresist. Prebaking the photoresist at a temperature of between about 150 and 220°C. for a time of from about 15 minutes to about 30 minutes, prior to stripping the positive organic photoresist layer with the triamine, enhances the removal.

Abstract: Raw coffee beans or nuts (2) are put in a revolving drum (3a) divided into at least four independent modular sectors (17) each of which carries a given quantity of the product through a succession of similarly independent work stations (12, 13, 9, 14) to be heated, roasted, cooled, and discharged ultimately through an outlet (4). The air used to cool the product is recycled from the roasting station (13), being drawn from the drum (3a) into a separator (5), freed of any skins or husks (6) that may be entrained from the roast, then directed into a cooling system (7) that lowers its temperature to sub-ambient level before returning it to the drum; the option exists of enriching the recycled with additional aromas before it finally enters the cooling station.

Abstract: A reagent for use in a fluorescence polarisation immunoassay for 11-nor- DELTA 9-tetrahydrocannabinol-9-carboxylic acid (an important metabolite of the narcotic drug marihuana) contains, besides an antibody for this metabolite and an aqueous buffer, a liberating agent. This liberating agent binds to and blocks non-specific binding sites on the human serum albumin present in urine and on other proteins in the urine and thus makes it possible to measure more reliably the metabolite "liberated" in this way. Also described are variants of a method for measuring the metabolite carried out using the liberating agent.
