20100304594 | Connector - A plate-like connection target is inserted into a connector along a first direction. The connector has a first metal member having a first metal abutment portion, a second metal member having a second metal abutment portion, and an actuator operable to push the second metal abutment portion toward the first metal abutment portion for holding the plate-like connection target between the first metal abutment portion and the second metal abutment portion in a second direction perpendicular to the first direction in a state in which the plate-like connection target has been inserted in the connector. | 12-02-2010 |
20110028018 | Connector - A connector has a housing, an insertion slot into which a connection target is inserted, an actuator and a contact. The actuator has a pusher. The actuator is held on the housing so as to be turnable between an open position and a close position. The actuator allows the connection target to be inserted into the insertion slot when the actuator is positioned at the open position. The pusher pushes the inserted connection target when the actuator is positioned at the close position. The contact is held by the housing. The contact includes a spring section and a supported section supported by the spring section. The supported section includes a press section and a contacting section. The press section presses the pusher against the inserted connection target and receives, from the pusher, a reaction force directed away from the connection target when the actuator is located at the close position. The contacting section is brought into contact with the connection target when the press section is moved away from the connection target by the reaction force. | 02-03-2011 |

20100302670 | DISK DRIVE - To provide a disk drive capable of inhibiting the occurrence of acoustic noise caused by a voltage pulse when the head is retracted using a speed control method using voltage obtained by rectifying a back electromotive force after the power source has been cut off from the rotation of a spindle motor. Retraction control circuit is used to control the on and off modes of transistors in accordance with the speed of VCM. The voltage across VCM becomes a voltage that can be regulated with VCM voltage control circuit. At this time, voltage is supplied to the terminals based on the voltage of ISO5V that is the rectified voltage of the back electromotive force of the spindle motor and the pulsating voltage is synchronized and produced at both terminals. As a result, the potential difference across VCM is such that the pulsating voltage is negated and acoustic noise is inhibited. | 12-02-2010 |
