摘要： A head suspension restricts deformation of a flexure caused by frictional force produced between a hard disk and a slider when the hard disk turns in a reverse direction. The head suspension has a load beam resiliently supported with a base. The base is supported with an arm that is turned around an axis. The load beam applies load onto a head having a slider to write and read data to and from the hard disk. The flexure is attached to the load beam and has a tongue that supports the slider. The flexure is provided with a limiter that limits displacement of the tongue due to frictional force produced between the hard disk and the slider when the hard disk is reversely turned. The limiter is on the base side and faces a free end of the tongue. The limiter is integrally formed from a part of the flexure, to face the free end of the tongue.

摘要： A parallel mechanism includes a base portion, a bracket to which an end effecter is attached, a plurality of actuators attached to the base portion, a plurality of arms through which the plurality of actuators and the bracket are coupled together in parallel, and a control device arranged to control the actuators. When the end effecter in a stopped state is moved to a target position, the control device is arranged to control the actuators so that a level of acceleration at which the end effecter is accelerated is higher than a level of deceleration at which the end effecter is decelerated.

摘要： A carriage for a disc device, which has a top arm, bottom arm, and mid arm, has a main mode, end arm mode, and mid arm mode as a frequency response obtained when subjected to a vertical shake. In the main mode, all of the top, bottom, and mid arms swing at a first frequency within the same phase in a primary bending mode. In an end arm mode, the top and bottom arms swing at a second frequency higher than the first frequency within opposite phases and with an amplitude larger than that of the mid arm. In the mid arm mode, the mid arm swings at a third frequency having a difference of 50 Hz or less from the second frequency within the same phase as in the main mode, and the top and bottom arms swing within the phase opposite from that in the main mode.

摘要： A suspension for disc drive comprises a load beam fitted with a flexure, an actuator base including a base plate, a hinge member thinner than the base plate, and a pair of piezoelectric ceramic elements. The piezoelectric ceramic elements displace the distal end portion of the load beam in a sway direction when supplied with voltage. Each piezoelectric ceramic element is stored in an opening portion in the actuator base. A covering material such as an adhesive agent that fills the space between the peripheral edge portion of the piezoelectric ceramic element and the actuator base forms a cover portion that covers the opposite end faces and the opposite side faces of the ceramic element.

摘要： A suspension for disc drive comprises a load beam fitted with a flexure, an actuator base including a base plate, a hinge member thinner than the base plate, and a pair of piezoelectric ceramic elements. Each piezoelectric ceramic element is stored in an opening portion in the actuator base and fixed to the actuator base by an adhesive layer. The adhesive layer includes an electrical insulating adhesive agent and a large number of fillers of an insulating material mixed in the adhesive agent. The fillers are interposed between each piezoelectric ceramic element and the actuator base to secure a clearance for electrical insulation between the two.

摘要： A parallel mechanism includes a base, actuators attached to the base, a plurality of arms coupled together in parallel, and a sensing device. Each of the arms has a first link, one end of which is coupled to the actuator, a second link through which the other end of the first link and a bracket are coupled together, a ball joint through which one end of the second link and the other end of the first link are swingably coupled together, and a ball joint through which the other end of the second link and the bracket are swingably coupled together. Each of the ball joints includes a ball stud including a ball-shaped head, a socket swingably holding the ball-shaped head of the ball stud, and a conductive member interposed between the ball-shaped head and the socket. The sensing device senses when at least one of the plurality of ball joints is loose, based on whether or not the ball stud and the socket are electrically continuous with one another.
