摘要： A head actuator for a magnetic disk drive unit which eliminates the possibility of track slip due to a mechanical external force and allows high-speed access. The head actuator includes a carriage having a body provided rotatably to a shaft fixed to a housing and an arm fixed to the body so as to extend substantially perpendicularly to the shaft, a supporting member mounted on the body on its side opposite to the arm with respect to the shaft, and a coil fixed to the supporting member and receiving a driving force from a static magnetic field. The supporting member is formed of a material having a specific gravity larger than that of a material forming the body of the carriage.

摘要： Hydrorefining catalyst contains 0.1 to 25 wt % in total of at least one hydrogenation active metal element selected from elements of Group 6, Group 8, Group 9, and Group 10 of the Periodic Table, and 0.1 to 3 wt % potassium on a carrier formed of porous inorganic oxide. The concentration distribution of the hydrogenation active metal element is higher in the central part than in the peripheral part of the catalyst, and the concentration distribution of potassium is higher in the peripheral part than in the central part of the catalyst. The pores on the outside surface of the catalyst are not plugged by the metal content of hetero compounds and hetero compounds can be efficiently diffused to inside the catalyst. As a result, long-term retention of a state of high activity is possible.

摘要： A breather structure for ventilation between the inside and outside of the housing of the disk drive is realized by a simple, inexpensive construction. The cover structure is for a disk drive provided on a base with a spindle motor carrying recording disks and an actuator for driving a carriage carrying heads for writing information on the disks, with the inside sealed airtight by attaching a cover to the gas through a gasket, and with an antivibration plate for preventing vibration and noise from generating when driving the disks at the surface of the cover contacting the outside air either directly or through a viscoelastic member. A ventilation groove for ventilating between the inside and outside of the disk drive is realized by forming a breather passage designed considering the passage conductance between the cover and the antivibration plate, providing a breather vent communicating the breather passage with the outside in the antivibration plate at one end of the breather passage, and providing a breather vent communicating the breather passage with the inside of the disk drive at the cover at the other end.
