摘要:
A tool joint part has a PIC incorporated therein for storing data which can be used to identify the tool to which the joint part is interconnected. PICs are incorporated into tool conditioning circuits. An intermediate circuit operates to match the identity stored digitally in a first PIC with the identity stored digitally in another PIC and thereby connect the tool to the appropriate tool conditioning circuit.

A method for use in the manufacture of an electronic circuit comprising at least one substantially planar electronic device is disclosed. The method comprises: forming a structure comprising a layer of active material, at least a first conductive track spaced from and extending in a plane generally parallel to the layer of active material, and a layer of insulative material separating the first conductive track from the layer of active material, the layer of active material having a plurality of insulative features formed therein, each insulative feature at least partly inhibiting electrical current flow in the layer of active material and the plurality of insulative features defining at least a first substantially planar electronic device in the layer of active material comprising at least a respective first terminal and a respective second terminal, each terminal comprising a respective area of the layer of active material, and at least a portion of said first conductive track overlapping one of the first and second terminals; forming a first hole in said structure, said first hole extending through the layer of insulative material and connecting an overlapping portion of the first conductive track to one of the first and second terminals; and filling said first hole at least partly with electrically conductive material so as to provide an electrical connection between the first conductive track and one of the first and second terminals.

摘要:
A user logic design for a mask-programmable logic device (“MPLD”) may be designed on a comparable or compatible user-programmable logic device (“UPLD”) and migrated to the MPLD, or may be designed directly on an MPLD. If the design is designed on a UPLD, the constraints of the target MPLD—i.e., differences between the devices—are taken into account so that the migration will be successful. If the design is designed directly on an MPLD, constraints of a comparable compatible UPLD are taken into account if the user indicates that the design will be migrated to the UPLD for testing. This means that when a logic design is intended to be migrated back-and-forth between a UPLD and an MPLD, only the intersection of features can be used. To facilitate migration, fixed mappings between pairs of devices may be created.

A fuel composition containing a major amount of a fuel suitable for use in a compression-ignition engine, which fuel contains one or more hydrocarbon components boiling within the diesel boiling range, at least one of which hydrocarbon components has been treated with a metal adsorbing or absorbing material in a different physical phase from the hydrocarbon component(s), preferably to reduce the level of at least one metal, more preferably the level of at least one heavier metal, most preferably the level of zinc, in said at least one hydrocarbon component, said treatment including physical separation of the hydrocarbon component from the metal adsorbing or absorbing phase, is used to operate a compression-ignition engine, and/or a vehicle which is driven by a compression-ignition engine, for the purpose of reducing subsequent formation of deposits, preferably combustion related deposits, during engine operation in the compression-ignition engine into which the fuel composition is introduced and/or of removing from the engine previously incurred deposits.
摘要:
A method of compressing a character by determining an overall code specific to the character comprising the steps of:a) grouping the characters in terms of a common behaviour pattern;b) where the number of characters within that group is odd, creating a two new groups of character, one new group containing just one character and the other new group containing the remaining characters;c) for each new group from of step b) said groups from step a) which have an even number of characters, assigning a group specific code d) where there is more than one character in the group referred to in step c) assigning a character identifier code to identify an individual character within the group, e) the overall character code comprising of the cocatenated group specific and identifier codes.
摘要:
A cabinet for retractably storing audio/video equipment is provided. The cabinet comprises a main body and a flip-up/slide-in top door adapted to rotate from a horizontal to a vertical position, and thereafter descend vertically within the main body. A support shelf is disposed within the main body and adapted to slideably vertically traverse within the main body as the top door descends. Connecting means are provided for elevating the support shelf when the top door descends within the main body.
