摘要:
A method of manufacturing a wiring board by utilizing electro plating characterized in that: when a wiring pattern is formed on the board by utilizing electro plating, an unnecessary portion does not remain on the wiring pattern. The method comprises: first electroless plating layers (19) are formed on both sides of an insulating substrate (1), which are covered with metallic foils (17) in advance, on which first electro plating layers (21) are formed; wiring patterns are formed by etching so as not to extend to the end edge of the substrate; second electroless plating layers (41) are formed on all of the surfaces of the substrate; a plating resist pattern (43) is formed so that only a predetermined portion of the wiring patterns is exposed; a second electro plating layer (27, 29) is formed on the predetermined portion of the wiring patterns by supplying an electric power from the second electroless plating layers; the plating resist pattern and the second electroless plating layers are removed; and a solder resist (45) is formed so that predetermined portions of the wiring patterns are exposed.

When a wiring pattern is formed on a wiring board utilizing electroplating, an unnecessary portion is removed by proceeding as follows. First electroless plating layers are formed on both sides of an insulating substrate, which are covered with metallic foils in advance. On the first electroplating layers, wiring patterns are formed by etching so as not to extend to the end edge of the substrate. Then, a plating resist pattern is formed so that only a predetermined portion of the wiring patterns is exposed and a second electroplating layer is formed on the predetermined portion of the wiring patterns by supplying electric power from second electroless plating layers. Finally, the plating resist pattern and the second electroless plating layers are removed, and a solder resist is formed so that predetermined portions of the wiring patterns are exposed.

The present invention provides a pipelined computer which processes variable-length data without using branch instructions for speedy execution of a variable-length data-handling software instruction. Upon receiving a variable-length data-handling instruction from an instruction supply unit 1, an instruction division unit 2 divides the instruction into a plurality of derived micro instructions that handle fixed-length data. A reservation station 5 sends the derived micro instructions to an execution unit 6 and a redundant instruction detection unit 9 in a sequence in which the derived micro instructions were generated during the division. The redundant instruction detection unit 9 monitors the remaining derived micro instructions. An instruction deletion control unit 8 deletes redundant micro instructions in the reservation station 5. An instruction end operation unit 7 sets the state of the redundant derived micro instructions in the reorder buffer 4 to “execution completed state”.

Catalyst compositions suitable for use in the exhaust gas recycle stream of an internal combustion engine are provided. Such catalyst compositions typically provide significant amounts of methane in addition to syngas. A reformer incorporating such a catalyst for use in an exhaust gas recycle portion of an internal combustion engine powertrain is described. A powertrain incorporating such a reformer, a method of increasing the octane rating of an exhaust gas recycle stream, and a method of operating an internal combustion engine using methane-assisted combustion are also described.
