摘要： In a hydrodynamic bearing apparatus for rotatably supporting a rotor by a hydrodynamic bearing, wear of the apparatus caused by sliding contact of dynamic pressure bearing faces in starting and stopping thereof is prevented to thereby promote durability, working of a dynamic pressure generating groove is facilitated and the bearing faces are prevented from being adsorbed to each other. By providing a low friction metal layer having water repellency at dynamic pressure bearing portions of a hydrodynamic bearing apparatus, friction can be reduced, wear or dust formation can effectively be restrained and the bearing faces can be prevented from being adsorbed to each other by dew condensation.

摘要： A hydrogen storage material is disclosed with no collapse due to pulverization of hydrogen storage alloy particles by repeated hydrogen absorption and desorption thereby permitting repeated use while manifesting excellent electric and thermal conductivities. Pressure molding of hydrogen storage alloy particles, each being covered with a plated metal film having microgranules of a thermoplastic resin, at a temperature higher than a glass transition temperature or a melting point of and below a thermal decomposition temperature of the thermoplastic resin can produce a porous hydrogen storage material of hydrogen storage alloy particles being bonded to each other via the thermoplastic resin. The hydrogen storage material can become firm and strong because the plated metal films covering the hydrogen storage alloy particles are clasped with each other complexly.
