摘要： A magnetic head device includes a TMR sensor or a CPP GMR sensor. Shield layers are disposed in contact with the top and bottom of a sensor body. A sensing current is supplied to the sensor body through the shield layers. Lead layers are connected to the shield layers and extend to below conductive pads. Ends of the lead layers are electrically connected to the conductive pads via lifting layers. Heat-conducting layers are disposed below the ends of the lead layers. An insulating layer is formed between the heat-conducting layers and an end surface of a slider body to such a thickness that it does not obstruct heat transfer. Heat applied from a molten solder to the lead layers is released to the slider body through the heat-conducting layers. This prevents the shield layers from being heated to high temperature.

摘要： A torque converter including a one-way clutch for supporting a stator radially on a fixed member in such a manner that the stator is rotatable in one direction, and a pair of thrust bearings for supporting the stator axially between a pump impeller and a turbine runner, wherein the diameters of the one-way clutch and both of the thrust bearings are different, and the thrust bearings do not axially overlap at least side bearings of the one-way clutch. With this arrangement, thrust force is not applied to the side bearings, and thus, the side bearings are thinner than conventional side bearings. Accordingly, the area radially inside of the stator in the torque converter is axially shortened.

摘要： In a perpendicular magnetic recording head having a main magnetic pole layer and a return yoke layer which are laminated with a magnetic gap layer interposed therebetween on a medium-opposing surface, a pair of side coils constituting respective electrically closed circuits on a surface parallel to the medium-opposing surface are provided on both sides in a track width direction of a magnetic pole part of the main magnetic pole layer. When a leakage magnetic field spreading from the magnetic pole part of the main magnetic pole layer passes through the pair of side coils, the pair of side coils generate a demagnetizing field in such a direction as to cancel a magnetic flux change thereof, thereby preventing the leakage magnetic flux from spreading.
