    • The present invention relates to an annular sliding fluoroplastics member which is requested to have good mechanical properties, resistance to abrasion and wear, thermal conductivity, heat resistance, and the like, and also to a method of producing such an annular sliding fluoroplastics member. The annular sliding fluoroplastics member of the invention has a composite structure which mainly consists of fluorine plastics and short fibers, and 20 or more wt. % of short fibers by weight of a total amount of the short fibers are oriented in a direction along which a burden of a load is large. According to this configuration, the buckling resistance and the pressure resistance are enhanced. A member having a high buckling resistance can be used in a thrust slide bearing or a thrust washer in which a large press load is applied in the axial direction, and a member having a high pressure resistance can be used in a radial slide bearing in which a large press load is applied in a radial direction. In some cases, in the annular sliding fluoroplastics member of the invention, filaments consisting of long fibers may be stitched to the inner peripheral face or the like, the surface is covered with an expanded graphite sheet, or the member is impregnated with a lubricant. The member having such a structure is excellent in buckling resistance and pressure resistance in a radial direction, and also in resistance to abrasion and wear, thermal conductivity, etc. According to the production method of the invention, a cutting work step can be omitted, and therefore materials can be prevented from being wastefully used, and the production cost can be reduced.

    • A large volume of digital media home information output from each of audio, visual, computer and communication (AVCC) apparatuses is transmitted to a digital media home information network at a high data speed and is received by one AVCC apparatus. Also, a small volume of digital environment home information output from each of self-management apparatuses such as an energy sensor, a security sensor and a health case sensor is transmitted to a digital environment home information network at a low data speed and is received by a digital information transmitting/receiving and protocol converting unit. In this unit, A protocol of the digital environment home information in the digital environment home information network is converted into that in the digital media home information network, and the data speed of the digital environment home information in the digital environment home information network is changed to that in the digital media home information network. Thereafter, the digital environment home information is received and processed by one of the AVCC apparatuses. Therefore, because both the networks are integrated by the converting unit, the digital media home information and the digital environment home information can be used at user's home at a low cost.

    • In a separator for a fuel cell and a method of producing a separator for a fuel cell according to the invention, bondcarbon is used in which composition ratios are set to 60 to 90 wt. % (preferably, 70 to 87 wt. %) of graphite powder having an average diameter in a range of 15 to 125 &mgr;m (preferably, 40 to 100 &mgr;m), and 10 to 40 wt. % (preferably, 13 to 30 wt. %) of a thermosetting resin. The compound is previously cold-molded into a shape similar to a final molded shape. The preliminary molded member is then placed in a mold, and then molded into a separator of the final shape by applying a pressure of a range of 10 to 100 MPa. The surface roughness Ra of at least a portion of the separator contacting with an electrode is set to a range of 0.1 to 0.5 &mgr;m. According to this configuration, fluidity and moldability are excellent, the contact resistance can be set to a value lower than a requested value while ensuring strength sufficient for preventing the separator from suffering a damage such as a breakage due to vibrations or the like, and the low contact resistance can be stably maintained.
