Patent EP-0692863-A2 (EP)
Inventor: VINCIARELLI PATRIZIO
IPC: H02J1/10
Filed: 1995-07-12
Abstract: AC-DC boost switching power conversion apparatus delivers power from a bipolar input voltage source to a load at a unipolar load voltage without including rectifiers directly in the path of the current which is delivered from the input source. By this means the converter exhibits lower power loss in semiconductor diodes and switches than is exhibited by prior art converters which interpose a rectifier between a bipolar source and a DC-DC boost converter. Power processing is performed by circuitry of the kind which includes an inductive element in series with the bipolar input source, shunt paths which include switching elements for recirculating a bipolar shunt current back toward the input source, a controller for turning the switching elements on and off during each of a series of converter operating cycles and rectification elements which are arranged to deliver a unipolar current to the load. The switching elements may be bipolar switches, which can block a voltage of either polarity when on, and conduct a current of either polarity when off. In zero-current switching embodiments the converter includes circuit elements, such as inductors and capacitors, which allow for turning the switching elements on and off at zero current. One class of AC-DC converters, called "fully integrated boost bridge converters," may be used to construct converter arrays of arbitrary size in which each individual converter within the array will share both in the power delivered to the load and in the current withdrawn from, and returned to, the bipolar input source.

Abstract: The invention provides for a method and apparatus for the rapid generation of a snapshot copy of the data stored in a RAID storage subsystem (100). In addition to the user's configured RAID logical units (110), the present invention provides for the definition within a RAID controller (102) of a logical RAID level-one device (104) having an operational half (106) comprising the user's defined logical unit(s) and having a non-operational mirror component (108). The user access data is stored on the RAID subsystem by direct access to the user's defined logical unit and when a user directs a snapshot copy request to the operational half (106) and user defined logical units (110), the RAID controller (102) responds by temporarily configuring available storage capacity (e.g. spare disk drives) in the RAID subsystem to perform the function of the non-operational mirror component (108) of the logical RAID level-one device (104). Restoring operation of the non-operational mirror component (108) further causes the RAID controller (102) to rebuild the content of the restored mirror component by copying the content of the user's configured device(s) to the temporary replacement mirror component (124). Following completion of the rebuild operation, the logical RAID level-one device (104) is restored to the status of having a non-operational mirror component (108). The data copied to the temporarily reconfigured available storage capacity is then returned to the user requesting the snapshot data for further processing as, for example, backup.

Abstract: Selon un mode de réalisation, la présente invention concerne un procédé pour programmer un contrôleur pour sélectionner, parmi plusieurs ensembles de codes infrarouges, un ensemble de codes infrarouges permettant de commander ultérieurement une communication par signaux infrarouges avec un magnétoscope à cassettes. Chaque ensemble de signaux infrarouges est prévu pour communiquer avec un magnétoscope correspondant différent. Dans ce but, chaque magnétoscope comprend un syntoniseur, qui, une fois accordé sur un canal réel de signaux vidéo de diffusion, fournit des signaux vidéo dérivés du canal réel à une sortie vidéo de ce dernier. Un signal est fourni au magnétoscope où le signal est prédéterminé par un code infrarouge sélectionné qui est choisi parmi un des ensembles de codes infrarouges. Cela amène le magnétoscope à effectuer une opération prédéterminée. La sortie vidéo du magnétoscope est contrôlée afin de détecter une condition de signal prédéterminée, tel qu'un signal vidéo présent, ou afin de détecter une diffusion d'étiquettes dans les signaux vidéo. Un ensemble de codes infrarouges est ensuite sélectionné en vue d'une communication ultérieure par signaux avec le magnétoscope. L'ensemble de codes infrarouges qui est choisi est celui à partir duquel est sélectionné le code infrarouge, qui conduit à la condition de signal prédéterminée.

Abstract: Disclosed is a device for processing media to check the validity of checks and other negotiable instruments and print as necessary on said media. The device comprises in sequence along a transport path (9) from an insertion opening (6) a transportation mechanism (3), a printing mechanism (4) and a reading mechanism (5). When the medium (8) is transported by the transportation mechanism (3) along the transport path (9) to a predetermined position, the check is positioned between a presser roller (51) and a sensor (52) of the reading mechanism (5). The presser roller (51) then presses the check (8) against the sensor (52) while the transportation mechanism (3) pulls the check and information recorded on the check is read. This operation straightens wrinkles and removes slack from check (8) to reduce reading errors. Based on the read information, a printing process is then executed by the printing mechanism (4) and the check is ejected from the insertion opening (6). Task efficiency is therefore good, and the occupied space can be minimized.

as an exhaust gas oxygen sensor, a heat sensor and a heater. More
specifically the invention provides an electronic component
integral with a heat resistant terminal that is pressure-fitting
or shrink-fitted on a ceramic element of the electronic component.
This electronic components shows a great mechanical and
electrical performance, withstanding the high temperature
environment beyond 400 up to 800°C to which the ceramic element
of the component is required to expose. 
     The terminal incorporated in this high temperature
electronic component comprises a plurality of metal wire leads
that electrically connect to a surface of a bar-like ceramic
element, at least two ceramic insulators that surround the leads,
and a thermal resistant metal ring that shrink-fits or
pressure-fits around the ceramic insulators so that the metal
leads press in a radial direction holding the element firmly. 
     The thermal resistant metal ring to be used for this shrink
fit or pressure fit is preferably made of an alloy such as Incoloy
909, Inconel 650, and Waspaloy and the like, thereby preventing
the metal leads from coming off at such high temperature. 
     The terminal integrated with the ceramic element by the
shrink fitting method according to the invention, minimizes the
number of parts , attaining a miniaturization of such high
temperature electronic component in a low cost.
