    摘要: A fluid bearing device is manufactured with a high adhesive strength in fixing another member by adhesion to a resin housing. A bearing sleeve is secured in position inside the resin housing, and a shaft member is radially supported in a non-contact fashion by a dynamic pressure action of lubricant generated in a radial bearing clearance between the shaft member and the bearing sleeve. A metal bracket for mounting the stator coil of a motor is fixed by adhesion to the outer periphery of the housing, in which the adhesion portion of the outer periphery of the housing to be fixed to the bracket is roughened, setting the surface roughness to 0.5 μmRa to 2.0 μmRa.

    摘要: A mobile radio communication system estimates the positional relationship between an own moving terminal and another moving terminal around a view obstruction. If the absolute value of the difference between detected reception power levels is lower than a first power threshold value, the own moving terminal determines that the other moving terminal is positioned within the visual range of the own moving terminal, the distance from the own moving terminal to the other moving terminal being shorter than a predetermined distance BP, or that the other moving terminal is positioned outside thereof, the distance to the visual range of the own moving terminal being shorter than the predetermined distance BP. Also if the absolute value is higher than or equal to the first power threshold value, the own moving terminal determines in a similar manner.
