IPC: H01J29/48
Filed: 1987-05-20
Abstract: A cathode ray tube having an electron gun (18) with a triode section (20) and a bi-potential focusing lens. 
     Generally such a focusing lens comprises two juxtaposed cylindrical electrodes of which the one nearer the screen is at the screen voltage of for example 30 kV. If it is desired to increase the diameter of the focusing electrode (24) then the voltage difference between the focusing electrode and the other, accelerating electrode has to be increased. The effect of this is to make the focusing electrode voltage unacceptably low with respect to the triode section. This problem can be overcome by providing a diaphragm (30) as an accelerating electrode, the diaphragm having an aperture whose area is less than half the cross-sectional area of the focusing electrode (24). The presence of the diaphragm (30) enables the focusing electrode (24) voltage to be increased to an acceptable level and be equal to that applied to a prefocusing lens electrode (22) enabling these electrodes (22, 24) to be interconnected electrically and/or mechanically.

Abstract: An improved two layer photolithographic process is disclosed for use in the construction of an inte­grated circuit structure. The improvements com­prise applying over a first photoresist layer sen­sitive to light below about 250 nm a second pho­toresist layer containing a selective solvent which is not a solvent for the first photoresist layer to inhibit reaction between the layers to form an interfacial layer therebetween; baking the second photoresist layer at a temperature below the glass transition temperature of the resin in the second photoresist layer to further suppress formation of the interfacial layer; and photostabilizing the remaining portions of the second layer after de­velopment at a wavelength range which will cross­link the remaining photoresist in the second layer to permit subsequent development of the lower pho­toresist layer, after exposure, with a high resolu­tion developer which will not dissolve the cross­linked upper photoresist. The crosslinked portions of the second photoresist layer protect the corres­ponding patterned portions of the first layer thereunder during subsequent dry etching to prevent erosion of the patterned first photoresist.

Abstract: An emergency lighting unit comprises a battery-­powered converter circuit for maintaining a discharge in a gas discharge or fluorescent light, the converter circuit also being arranged to generate a high voltage for striking the discharge in the light. When the mains supply is good and a switch is closed for turning on the light, the con­verter circuit is activated to provide its high voltage for striking the discharge, after which the discharge is maintained from the main supply. If the mains should then fail, the converter circuit provides its low voltage from its battery to maintain the discharge. If the mains fails whilst the light is switched off, the converter circuit strikes and then maintains the discharge in the light.

Abstract: In a serial printer, where a printing carriage moves along a printing line on guiding bars fixed to two side plates of the printer frame, the carriage position along the printing line is precisely defined by an encoding disk rotatably mounted on the carriage, and by a flexible cable fixed to and stretched between the two side plates, which cable is wrapped around the encoder shaft, so that the carriage movement along the printing line causes a corresponding rotation of the encoding disk which, by cooperation with a detector, steadily fixed to the carriage enables for the generation of position signals which precisely define the carriage position.

Abstract: Each network node in a communications network maintains its own copy of the network topology database defining network resources. Each resource record contains a "timer" field which is initially set to a maximum value but which may be decremented on a daily basis. If the timer field is decremented to zero without being reset, the node unilaterally removes the resource record from its copy of the database. The timer field will normally reach zero only for obsolete resource records since each network node responsible for a resource broadcasts a timer-resetting message for the resource (1) each time the resource status changes, (2) when the node first joins or rejoins the network, and (3) on a periodic (weekly) basis regardless of whether conditions (1) or (2) have occurred.

Abstract: A biochemical analysis apparatus comprises a sample accommodating region, an accommodating region for test films containing a reagent which reacts with a liquid sample to give rise to a change in optical density, and a conveyor for sequentially pulling out each test film from the test film accommodating region. An applicator takes up the liquid sample from the sample accommodating region and applies it to the test film at the position to which the test film has been pulled out. An incubator incubates the sample-applied film portion for a predetermined time, and a detector measures the optical density of the sample-­applied film portion during or after the passage of the predetermined time. The conveyor, the incubator and the detector are provided to correspond to each of the test films, and a movement device moves the applicator to apply the liquid sample to the test films.

Abstract: The parts contain a polymeric material, an ion-selective component and possibly a plasticiser and are used to determine the concentration of ions in liquid media. The polymeric material in these ion-selective parts is a copolymer in which 5 - 25 mol % of the monomer units carry one or more hydrophilic substituents which are hydroxyl groups, carboxyl groups, sulpho groups and/or phosphono groups. The ion-selective parts have, by comparison with ion-selective parts whose polymeric material contains fewer or no hydrophilic groups, a greater constancy of the standard potential and a lower asymmetry potential or no asymmetry potential whatever. These properties of the ion-selective parts are also retained after they have come into contact with solutions which contain proteins and, accordingly, these ion-selective parts are suitable for use in devices for determining the concentration of ions in clinical chemistry, for example in whole blood, serum or plasma. 
<??>The polymer components carrying hydrophilic groups are prepared by hydrolysing a corresponding homopolymer or copolymer in which the hydrophilic groups are present in protected form, for example as esters.
