  • Publication number: 20050044204
    Abstract: A computer terminal 110 connected to a manufacturing apparatus 120 as an object of the maintenance management is connected to a server machine 210 providing a maintenance management service by a network 500, enabling bi-directional communication. The computer terminal transmits status information on an apparatus as an object of the maintenance management to the server machine in response to a status information transmission request received from a server at every predetermined interval. The server machine includes a status point information management database for storing status points generated according to status information and determines whether status information has been received at every predetermined interval. Each time it is determined that status information is received, a predetermined point is added so as to update the status points of the status point information management database. This can encourage a customer to perform maintenance by him/herself and reduce workload of a serviceman.

    Abstract: An object of the present invention is to provide a filler metal for an aluminum brazing sheet for heat exchangers capable of preventing or controlling occurrence of a melting hole during heating for brazing, and a method of manufacturing the same. In an Al—Si alloy filler metal which is clad on the aluminum brazing sheet and melted during heating for brazing, the maximum particle diameter of a coarse Si particle crystallized in the eutectic structure of the filler metal is 20 ?m or less. Provided that an average value and a standard deviation in a normal distribution of the particle diameter of the coarse Si particle in the filler metal are respectively ? and ?, (?+3?) is preferably 10 ?m or less. This brazing sheet is obtained by a method of adding a specific amount of Na, Sr, or Sb to the filler metal, a method of limiting the amount of impurities in the filler metal within a specific range, a method of specifying a cooling rate during the casting of the filler metal, or the like.

  • Publication number: 20040157347
    Abstract: Process exhaust gas is sampled, and the components of the process exhaust gas are analyzed by a Fourier-transform infrared spectroscope (FT-IR) (26). The analysis result is compared with a reference analysis result obtained from an analysis of process exhaust gas generated in an operation performed under reference process conditions. If the amount of a gas component changes to an amount that is outside a predetermined range set around a reference value obtained from the reference analysis result, a signal indicating a process error is outputted. Instead of the output of the signal indicating a process error, the process conditions can be automatically adjusted.

  • Patent number: 6692239
    Abstract: A reciprocating compressor of un-lubricating type, equipped with a cooling device including a cooling fan beneath a motor and provided with four gas compressors, each having a cylinder and a piston. The pistons of each gas compressor cooperate by converting a rotating motion of a crankpin of a crankshaft provided on an electric drive source via two yokes having a phase difference of 90 degrees therebetween to a reciprocating motion by a scotch yoke mechanism. The flows of compressed gases from each gas compressor are joined to one place by connecting tubes to be discharged. The lengths of each connecting tube are selected such that pressure waves of the compressed gases compete with each other at the joining point for a time period encompassing one rotation of the crankpin, whereby a pulsation resulting from gas flow discharged in concentration is decreased.
