Disclosed herein is a disk drive including a housing having a base, a disk rotatably mounted in the housing and having a plurality of tracks, a negative pressure type head slider having a transducer for reading/writing data from/to a disk, an actuator for moving the head slider across tracks of the disk, a mechanism for controlling the actuator to load/unload the head slider with respect to the disk, and a ramp member fixed to the base for supporting the head slider unloaded. The actuator includes a suspension having a gimbal, a reinforcing plate fixed to the suspension, and the head slider mounted on the gimbal. The reinforcing plate has a pivot for supporting the head slider at a position shifted from the longitudinal center of the head slider toward an air outlet end of the head slider by a distance less than 20% of the length of the head slider.
摘要:
A frictional engaging device and frictional engagement control method, wherein the phenomenon of the frictional coefficient of the friction surfaces of a friction engagement device being changed when an electric field is applied to the friction surfaces, is utilized to control the transmittal force. Under the action of a pushing force, friction engagement members are brought into direct contact with each other for frictional engagement. When an electric field is applied between the frictional engagement members, the frictional coefficient of the friction surfaces changes, which means that the transmittal force can be changed. An example of the frictional engagement device is a clutch device (10). A friction member (20) made of insulation material is attached to an input disk (16) and engages an output disk (22). The friction surfaces are lubricated. A control device (30) controls a voltage applying device (28) and applies a voltage to an electrode (26) to provide a desired transmittal force.

摘要:
The present invention relates to a process for producing an anode for a secondary battery, which is capable to reduce a contact resistance between a sintered material which contains silicon as an anode active material and a current collector. A binder and a solvent are mixed with a silicon-containing anode material to prepare a slurry. A base material made of a foil or mesh of conductive metal is coated with the slurry, and the solvent is removed to form a coated film. The coated film is sintered in a non-oxidizing atmosphere, thereby integrating a sintered material of the coated film with the base material.

摘要:
When a digital image recording means records digital image on an image recording medium based on order information or on digital image data, a computing means calculates digital image layout information, and calculates, based on the digital image layout information, X-cut size information used for cutting the image recording medium in the direction perpendicular to the conveyance direction of the conveyance means and Y-cut size information used for cutting the image recording medium in the direction perpendicular to the cutting direction for the X-cut. A cutting means which cuts the image recording medium into a prescribed size has an X-cut means to cut the image recording medium in the direction perpendicular to the conveyance direction of the conveyance means in accordance with the X-cut size information and a Y-cut means to cut the image recording medium in the direction perpendicular to the cutting direction of the X-cut in accordance with the Y-cut size information.
