    摘要： In applying an intermediate coating layer of thermoplastic resin onto the periphery of a central tensile member and applying a main coating of polyethylene resin, having continuous spiral grooves that are for accommodating optical fibers and are inverted periodically in direction along the length direction, onto the outer periphery of the abovementioned intermediate coating layer, a cooling medium is blown or made to flow with priority onto the grooves after melt discharge to form a spacer with which even though the minimum rib thickness of the ribs that define the abovementioned spiral grooves is 1.0 mm or less, the groove inclination angle α of the spacer cross section at the inversion parts is 18° or less.

    摘要： A polyethylene spacer for optical fiber cable including a central tensile member, an intermediate coating layer arranged on an outer periphery of the central tensile member and being compatible with polyethylene and a main coating arranged on an outer periphery of the intermediate coating layer and having continuous spiral grooves for accommodating optical fibers and which are inverted periodically in a lengthwise direction. The main coating is formed from polyethylene resin. The spacer includes ribs defining the spiral grooves. A minimum thickness of the ribs is 1.0 mm or less, the groove inclination angle &agr; of a cross section of the spacer at inversion part is 18° or less. A resin density of a root part of each rib is the lowest in comparison to a resin density at a tip part of the rib and central parts of the rib between the root part and the tip part.

    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： An internal combustion engine includes a control shaft, an actuator, and an oil accumulation portion. The control shaft is configured to vary a lift amount of an engine valve in accordance with a rotational position of the control shaft. The actuator is configured to drive the control shaft to make the lift amount of the engine valve to be a start lift amount before the engine is started. The actuator includes a worm wheel and a worm. The worm wheel is provided at the control shaft and is disposed in an engine body. The worm is disposed below the control shaft and engages with the worm wheel. The oil accumulation portion is provided at at least one of the control shaft and the worm wheel and is configured to drop oil onto the worm in accordance with the rotation of the control shaft when the engine is started.
