Abstract: According to the present invention, each successive refresh to the multiple banks of a DRAM array is staggered by one clock period. Thus, the time required to refresh one row in each DRAM of each bank at 10 MHz, for example, is equal to 0.7 µsec., or 4.4% of the total allowable maximum time between refresh cycles. This staggered refresh technique avoids large power supply current spikes while minimizing the effect on memory access bandwidth.

Abstract: A two stage, electron beam projection system includes a target, a source of an electron beam and means for projecting an electron beam towards the target with its upper surface defining a target plane. A magnetic projection lens has a principal plane and a back focal plane located between said means for projecting and the target. The means for projecting provides an electron beam directed towards the target. First stage means provides deflection of the beam from area to area within a field. Second stage means provides for deflection of the beam for providing deflection of the beam within an area within a field. The beam crossing the back focal plane produces a telecentric condition of the beam in the image plane with the beam substantially normal to tghe target plane from the principal plane to the target plane. The magnetic projection lens includes a magnetic structure providing for magnetic compensation positioned within the bore of the projection lens, which produces a compensating magnetic field substantially proportional to the first derivative of the axial magnetic projection field. The axial magnetic projection field provides substantially a zero first derivative of the axial magnetic projection field in the vicinity of the target. The projection system projects on the target plane from the projection system as deflected by the upper and lower stages, at all times maintaining the telecentric condition of the electron beam at the target plane throughout the entire range of deflection of the beam, assuring minimum errors due to target height variations.

Abstract: The invention relates to a process for the production of an unreinforced, annular tube which consists of a rubber compound, in particular it relates to a process for the production of a bicycle tube, in which first of all a hollow profile of an essentially circular cross-section is extruded from the rubber compound, a section for each tube is cut off to a length corresponding to the circumferential length of the tube to be produced, this section is then joined up into a continuous ring and this ring is vulcanised in a multipart mould. In order to produce mould-heated tubes more cheaply and with less wastage, it is proposed by the invention that once the unvulcanised tube has been joined together into a continuous ring it is first of all prevulcanised in a formless state in a vessel until it has reached a degree of vulcanisation of at least 30% and only then is vulcanised to completion in a multipart mould. The rubber compound preferably reaches a degree of vulcanisation of between 40% and 60% in the prevulcanisation stage.

Abstract: In a method and apparatus for calibrating absolute and relative measurements of modulation and/or demodulation transfer characteristics of electro-optical and opto-­electrical devices during setup of a lightwave component measurement system (10) for characterizing performance of fiber optic systems and associated components, an initial calibration reference is established based on the known characteristics of a lightwave source (14) and lightwave receiver (16) included in the lightwave component measurement system (10). A measurement is then performed on the calibration reference (the lightwave source or the lightwave receiver), and error correction data are produced and stored in a lightwave component analyzer included in the lightwave component measurement system. The modulation (or demodulation) transfer characteristics are preferably given in terms of the responsivity magnitude and phase versus modulation frequency. A device under test (DUT) then is measured when it replaces its calibrated counterpart in the measurement setup. The lightwave component analyzer uses the error correction data when the E/O or O/E characteristics of the DUT are measured.

Abstract: A long field file, managed using log-based recovery mechanisms, contains values associated with large data set items and contains allocation information controlling long field file space. Each long field has a compact descriptor pointing to associated multi-page block(s) of data in the long field file. The descriptor is in the database record which logically contains the long field. Long field data is shadowed in the long field file during updates and changes to the descriptor and long field file allocation information are logged. During long field data value deletion or replacement, the allocation information for the corresponding space in the long field file is marked free and locked until the deleting transaction completes, thereby insuring that deletes are undoable. 
     Support for storage, access and maintenance of long fields as logically integral components of recoverable database records is provided as well as row-level concurrency in minimization of long field data in the recovery log. Duplication in storing before and after images of long field data in the log is avoided. More efficient management of memory space freed by deletion of long field records is provided. Long field data is transferable directly without intermediate buffering including entire multi-page blocks of data and such transfer is effected with a single access to the storage device containing the data.

Abstract: An electronic braking system in a motor vehicle capable of towing a standard trailer not having its own EBS system has a separate pressure control channel for the generation of a trailer service brake pressure signal in the event that a driver's braking demand is sensed at any axle of the towing vehicle. The pressure signal level is set in the towing vehicle so as to be a function of the driver's electrical demand signal modified in dependence upon the load exerted by the trailer on the towing vehicle as measured at a towing link therebetween. Separate adaptive loops are provided in respect of the towing vehicle braking and the trailer braking, with the towing vehicle adaptive loop being responsive to deceleration error established by a comparison of vehicle retardation against driver braking demand, and with the trailer adaptive loop being responsive to towing link load, such as to obtain error signals which cause the adaptive adjustments to be made in the two loops in a mutually co-ordinated manner in order to achieve the required overall vehicle retardation.
