  • Patent number: 6908028
    Abstract: The present invention provides a method of manufacturing a honeycomb body (1) formed by winding a flat metal foil (3) and a corrugated metal foil (4) in layers and brazing them, capable of reducing the equipment cost of honeycomb body manufacturing facilities and conforming to the countermeasure against an engine misfire problem of the honeycomb body, without causing insufficient or excessive application of adhesive which is seen in the cases of adhesive application methods using rolls; and relates to a method of manufacturing a honeycomb body characterized by: applying an adhesive to the portions to be brazed of the flat or corrugated foil corresponding to a bonding portion (17) which is located at one or both ends of the honeycomb body and/or a bonding portion (18) inside the honeycomb body over a cross section which is located away from one or both ends thereof in the axial direction; then, winding the flat and corrugated foils in layers to form a honeycomb body; then, making the portion of one or both end

  • Patent number: 6689328
    Abstract: In order to improve solid phase diffusion bondability at contact portions between a metal flat foil and a metal corrugated foil together constituting a metal honeycomb body for a catalyst converter used for purifying an exhaust gas and to improve engine durability, the present invention comprises one or combination of the following structures; a structure wherein at least one of the metal foils has a foil thickness of less than 40 &mgr;m; a structure wherein an Al content after bonding is at least 3%; a structure wherein the surface condition of both metal foils in a width-wise direction has a predetermined surface coarseness or a predetermined surface shape and condition; and a structure wherein the width of contact portions between both metal foils is at least five times the thickness of the metal foils.

  • Patent number: 6574722
    Abstract: If a word line is selected by inputting an immediate value and base address, whose values are determined at different timings, to an adder, the access speed decreases due to the constraint of the base address whose value is determined at a later timing. According to this invention, decoding is performed by inputting only the immediate value whose value is determined earlier to an address decoder AD. Thereafter, a word line WL is selected by performing rotation using the base address whose value is determined at a later timing. This makes it possible to start decoding processing without waiting for the determination of the value of the base address and increase the overall access speed.

  • Patent number: 6389527
    Abstract: The present invention comprises a LSU which executes instructions relating to load/store. The LSU includes a DCACHE which temporarily stores data read from and written to the external memory, an SPRAM used to specific purposes other than cache, and an address generator generating virtual addresses for access to the DCACHE and the SPRAM. Because the SPRAM can load and store data by a pipeline of the LSU and exchanges data with an external memory through a DMA transfer, the present invention is especially available to high-speedily process a large amount of data such as the image data. Because the LSU can access the SPRAM with the same latency as that of the DCACHE, after data being stored in the external memory is transferred to the SPRAM, the processor can access the SPRAM in order to perform data process, and it is possible to process a large amount of data with shorter time than time necessary to directly access an external memory.
