The present invention proposes a thermoplastic resin material having both good characteristics and a high electric conductivity and comprising (a) graphite and carbon black, (b) graphite, carbon black, and lubricating oil, (c) carbon black and lubricating oil, or (d) fluorine resin in addition to (a)-(c).

Electric conductive and sliding resin material

Soldering material essentially consists of 20-50% of Pb, 0.5-less than 1% of Sb, 0.1-5% of In, and balance of Sn. Such material is suitable to solder electronic parts exposed to temperature variation and mechanical vibration.

Pb-Sn-Sb-In solder alloy

The present invention proposes a thermoplastic resin material having both good sliding characteristics and a high electric conductivity and comprising (a) graphite and carbon black, (b) graphite, carbon black, and lubricating oil, (c) carbon black and lubricating oil, or (d) fluorine resin in addition to (a)-(c).

Shoes for operatively connecting a swash-plate with the compression pistons of a swash-plate type compressor are made from a novel Cu-based alloy. Improved shoes are characterized by a combination of high heat conductivity and excellent wear resistance properties particularly when subjected to a lubricating condition so severe that no lubricating oil is supplied to the surface of the shoes at the initial period of the compressor operation. At least three alloying elements are selected from Mn, Si, Pb, Sn, the IVb and VIb groups of the periodic table, and added in predetermined amounts to the Cu-based alloy, so that the properties mentioned above are simultaneously obtained. The compressor according to the present invention can be reliably employed, without the occurrence of seizure over a long operational period for air-conditioning vehicles, in which the sliding condition of the shoes is drastically varied with the rotation of the engine.

Swash-plate-type compressor for air-conditioning vehicles

Shoes for operatively connecting a swash-plate with the compression pistons of a swash-plate type compressor are made from a novel Cu-based alloy. Improved shoes are characterized by a combination of high heat conductivity and excellent wear resistance properties particularly when subjected to a lubricating condition so severe that no lubricating oil is supplied to the surface of the shoes at the initial period of the compressor operation. Phosphorus and elements of C group (Pb and/or Sn), as well as elements of A group (Mn and Si) and/or B group (the IVb and VIb groups of the periodic table), are added in predetermined amounts to the Cu-based alloy, so that the properties mentioned above are simultaneously obtained. The compressor according to the present invention can be reliably employed, without the occurrence of seizure over a long operational period for air-conditioning vehicles, in which the sliding condition of the shoes is drastically varied with the rotation of the engine.
