  • Publication number: 20040205591
    Abstract: A method of processing a general-purpose XML document is executed to generate mapping data as a variable in a variable buffer when an input XML document is inputted through the effect of an input mapping function of a processing processor of a script language. When the output mapping function is started, the output XML document is supplied from the mapping data in the variable buffer.

  • Patent number: 6577632
    Abstract: A bit accommodation pattern table stores the information about bit accommodation patterns when data from a plurality of terminals are accommodated into predetermined multiplexing unit data in bits. A bit multiplexing/demultiplexing unit multiplexes the data from each of the plurality of terminals into the predetermined multiplexing unit data; demultiplexes the data addressed to each of the plurality of terminals, which is multiplexed into the predetermined multiplexing unit data; and transfers the demultiplexed data to each of the plurality of terminals. A cell conversion processing unit performs interconversion between the predetermined multiplexing unit data processed by the bit multiplexing/demultiplexing unit and cells corresponding to a predetermined link.

  • Patent number: 6032198
    Abstract: In a method for supporting the design of a plurality of programs distributed on a network and operated through the communication between the programs, each program is defined, a relation between programs is defined, interface information of each program is defined, and the interface defined for each program is converted into an interface definition language (IDL) format to generate an IDL file. The definition of each program and the definition of the relation between programs are performed by providing a graphic display screen to which a program represented by a symbol and a relation between programs represented by an arrow are inputted as definition information by a user. The definition of interface information is performed by inputting information defined by the user in an interactive manner.

  • Patent number: 4767070
    Abstract: A grinder for use in a grinding apparatus, comprising a pair of rotary and stationary discs facing each other, in which the rotary disc is rotated through a shaft by a drive motor, and in which a large number of grinding material particles are embedded in the surface of the discs to form microbites to grinding surfaces of the discs, and the strength of the grinding surface of the stationary disc is inferior to that of the rotary disc. The grinding is accomplished by fine cutting which is carried out by microbits formed of superhard grinding material particles having a sharp edge, rather than by mashing or abrasion. The grinder is formed as a cassette type so as to be replaced readily and quickly by new one. The grinder is provided with a clearance adjustor for adjusting the clearance between the rotary disc and the stationary disc.
