Abstract: Provided is a housing for a resin fluid dynamic bearing device in which deterioration with time of a fixing force for another member is mitigated and which can maintain a high bearing performance for a long period of time. The housing formed of a resin composition exhibiting a compression creep amount of 8% or less when a compressive pressure of 80 MPa is applied for 168 hours at an atmosphere temperature of 80° C., provides a sufficient fixing force for the another member fixed with a press-fitting force, for example, a bearing sleeve press-fitted into an inner periphery of the housing even after a long term use. Thus, there is no fear of fixing positions of the another member with respect to the housing being deviated and a high bearing performance is maintained for a long period of time.

Abstract: A fluid dynamic bearing device includes a resin member capable of suppressing the intrusion of a lubricating oil as much as possible even when carbon fibers are compounded. A housing part as the resin member can be obtained by injection-molding a resin composition in which PPS is a base resin, and carbon fibers are compounded. The housing part is in contact with an ester-based lubricating oil filled in the inside of the bearing. The plurality of carbon fibers bound with a binder material not containing an urethane resin are cut and the carbon fibers minced by cutting are compounded into PPS to thereby obtain the above-described resin composition.

Abstract: A magnetic data recording system employing a slider having a laser diode mounted to a side surface of the slider rather than to a back surface opposite the air bearing surface. The laser diode provides a light source for thermal assisted recording. Locating the laser diode at the side surface eliminates the possibility of contact between laser diodes of adjacent sliders and allows larger, more powerful laser diodes to be employed. In addition, placing the laser diode at the side allows a micro-actuator to be attached to the back side surface of the slider, thereby allowing both thermally assisted recording and micro-actuation to be used in the same recording system.

Abstract: A cast cylinder head 1 of an internal combustion engine to be mounted on a vehicle has an intake-side side wall 2i, an exhaust-side side wall 2e, and opposite end walls 3r and 3f. The walls 2i, 2e, 3r and 3f define a water jacket 8. A first cooling water exit part 11 and a second cooling water exit part 21 both having a solid structure are formed by casting integrally with one of the intake-side side wall 2i and the exhaust-side side wall 2e and with one of the end walls 3r and 3f, respectively. Cooling water exit openings 15,16 or 25,26 opening into the water jacket 8 are drilled selectively in either of the first cooling water exit part 11 and the second cooling water exit part 21 depending on the engine mounting position on the vehicle. Thus the same cylinder head can be used independently of the mounting orientation of the engine on the vehicle.
