Patent EP-0320059-A2 (EP)
Inventor: FREEMAN KENNETH GEORGE
IPC: H01J29/74
Filed: 1988-12-05
Abstract: In a flat cathode ray tube display apparatus a line scanning, low energy, electron beam (18) is directed substantially parallel to a faceplate (12) carrying a phosphor screen (14) in a space between a deflection electrode array (22) and an input side of an electron multiplier (16) adjacent the screen where it is deflected by the electrode array (22) in field scan manner towards the screen. The deflector electrodes (23) in the array correspond in number to the conventional raster lines to be displayed and are switched successively between two voltage levels to step the line scanning beam. The electrodes' voltage switching drive circuit (52) may be carried on a substrate adjacent the electrodes thereby reducing the number of leadthroughs in the tube's envelope (15). For colour display the screen comprises a pattern of different colour phosphor elements and a colour selection electrode arrangement (38) is situated at the output side of the multiplier (16). Three differently coloured, and accurately superimposed, lines are drawn on the screen in a normal line scan period between stepping of the beam.

Abstract: An image recording apparatus (1) includes a light source (3) for irradiating a microcapsule carrying photo-sensitive/pressure sensitive recording medium (P) for forming a latent image on it corresponding to an image of an original (G) upon photo-curing of the microcapsules, and a pressure unit (8) for developing an image on the photo-sensitive/pressure sensitive recording medium (P) upon rupture of remaining microcapsules. The apparatus includes control means (28) for controlling the atmosphere around at least the photo-sensitive/pressure sensitive recording medium (P) to within allowable ambient conditions so that development is carried out under optimum conditions. Typically both the temperature and humidity of the medium are controlled. Typically in an image transfer method, the photo-sensitive/pressure sensitive recording medium (P) includes a photo-sensitive pressure sensitive sheet which carries microcapsules encapsulating chromogenic material, photo sensitive composition and photo poymerization initiator, and a separate developer member (12) which carries a developer agent which reacts with the chromogenic material in the pressure unit (8). In a self-contained method, the photo-sensitive/pressure sensitive recording medium (P) includes a single sensitive sheet which carries all such substances.

Abstract: A cassette type magnetic recording/reproducing apparatus, such as a tape recorder, can accommodate a magnetic tape cassette (201) at a tape cassette attachment position within the main body of the apparatus so that the tape can be extracted by a loading mechanism so as to be loaded onto a predetermined tape running passage in the apparatus. The loading operation of the magnetic tape by the loading mechanism is enabled only when it is sensed by a switch (64) that a cassette holder (3) for attaching the tape cassette at the tape cassette attachment position is locked at the tape cassette attachment position and by switches (128) that the tape cassette is attached at the tape cassette attachment position. Thus a positive tape loading operation is ensured and the magnetic tape as well as various operating units within the main body of the apparatus are protected from damage.

Abstract: A method of making high melting point alloys. The reactive and non-reactive charge materials are separately refined as ini­tial alloys, generally as an alloy of a base element selected from the iron group of the Periodic Table, such as nickel, and at least one metallic element other than the base element. At least one first initial alloy and at least one second initial alloy are provided. The metallic elements other than the base element in the first initial alloys are relatively non-reactive in the mol­ten state, whereas the metallic elements in the second initial alloys are relatively reactive in the molten state. Amounts of the first and second initial alloys are selected to yield a pre­determined composition of the high melting point alloy upon melting. The selected amounts are melted to form a molten mix­ture having the predetermined composition, and then the molten mixture is solidified.

Abstract: The present invention relates to an arrangement for wireless earphones applicable in audio - systems or audio - visual systems of all kinds. 
     The present invention overcomes the problem of the high cons­truction, installation, operation, repair and maintenance cost of the wireless earphones of the prior art, due to the batteries and electro­nic circuits employed by the same, by means of a new system of wire­less earphones without batteries and electronic circuits, whose ope­ration is based on the inductive coupling between a space coil and an earphone coil, where the order of inductive coupling depends on the height of installation of the space coil, the circumferential length and number of turns of the two coils, the kind of used cores in the coils (air - or magnetic materials) and specific resistances of the materials used.

Abstract: The invention relates to a high frequency generator for a nuclear spin examining apparatus, with a modulator, in which a carrier is modulated with an envelope curve signal and with a transmission stage connected downstream of the modulator. In such a high frequency generator, the resources devoted to the transmission stage can be substantially reduced in that the modulator includes a first modulator part in which the envelope curve signal is converted into a sequence of equally long digital pulses, the density of which corresponds to the amplitude of the envelope curve signal, in that k different types of pulses are provided, in that during each pulse of a specified type the carrier is activated in each instance with a specified phase relation, which is different from the phase relations of the carrier which are linked to the pulses of the other types by 360 DEG /k or an integral multiple thereof, and in that the preferably rectangular carrier which is thus switched in a pulsed manner serves as switching signal for the transmission stage.

Abstract: A method is disclosed for enforcing referential constraints on a record-by-record basis, immediately before or after each record is manipulated and while the record is still accessed, significantly improving the system's performance. Each record is visited only once to do both the constraint checking and the manipulation (insert/update/­delete). If the constraint checking fails, then the entire relational operation of which the record manipulation is a part is backed out. For insertions, each record is first inserted 30, and then constraints respecting the record are enforced 32,34. For updates, the record is updated 48 after constraints respecting the record's primary key are enforced 40,42, and before constraints respecting its foreign key(s) are enforced 44,46. Deletions are performed 52 before the constraints on the deleted record are enforced 54,56. Cascade deleted 58 are handled recursively 60. The method correctly processes cyclic constraints and self-referencing rows without special handling.

Abstract: In a method of recycling a portion of the overhead vapour stream to enhance ethane recovery from a demethanizer (46), after the overhead vapour stream (32) is discharged from the demethanizer (46), a portion of it, reflux, is compressed in a cryogenic compressor (56) to a pressure greater than that of the demethanizer. Afterwards the pressurized reflux is chilled in a heat exchanger (54) causing at least a portion of it, and preferably all of it, to condense to a liquid. The pressure of this condensed reflux is then equalized to that of the demethanizer across a recycle valve (58) so that a liquid reflux can be fed back to the top of the demethanizer (46). This recycling of a liquid reflux enhances ethane recovery as a column bottoms product from the demethanizer (46).
