    • A call control system performs call control for a terminal which accesses different radio access network systems. A communication exchange processing apparatus includes: a device storing maximum bandwidth for specified calls processed in the radio access network system; a device measuring present bandwidth for specified calls presently processed in the radio access network system; a device computing a ratio of the present bandwidth to the maximum bandwidth for specified calls; and a device sending specified call band ratio information indicating the ratio of present bandwidth to maximum bandwidth for specified calls to a radio network control apparatus in the radio access network system and connected to the present communication exchange processing apparatus. The radio network control apparatus provided in the radio access network system includes a device sending the specified call band ratio information to a terminal which is connected to the present radio network control apparatus by radio communication.

    • The vacuum chuck, which is an accessory device for holding a workpiece in machining and inspection, has a suction head made of a porous sintered particles of a thermoplastic resin, e.g., a fluorocarbon resin, preferably, bonded to the chuck base. The suction head is free from the problem of unreliableness of holding of workpieces without the danger of damaging the workpiece. The outer peripheral surfaces of the sucking head are provided with an air-impermeable layer to increase the efficiency of suction by preventing leakage of vacuum. The water-and-oil-resistance of the suction head can be improved by blending the powder of the thermoplastic resin with a powder of a thermosetting resin, e.g., epoxy resin.
    • 作为用于在加工和检查中保持工件的辅助装置的真空吸盘具有由诸如氟碳树脂的热塑性树脂的多孔烧结颗粒制成的抽吸头,优选地结合到卡盘基座。 吸头不存在工件不牢固的问题,没有损坏工件的危险。 吸头的外周面设置有不透气层,通过防止真空泄漏来提高吸力效率。 可以通过将热塑性树脂的粉末与热固性树脂(例如环氧树脂)的粉末混合来提高吸头的耐油和耐油性。
