Embodiments of the invention provide a magnetic disk drive and its control method capable of effectively using the unrecordable area which is caused due to the composite magnetic head's gap between the read head and the write head. In one embodiment, a disk drive comprises a composite magnetic head structured in such a manner that during write the write head WH reaches each servo area earlier than the read head RH, and a read write control unit to control the write and read done by the composite magnetic head. On the disk, common servo data SP to be used both during read and during write, write servo data SW to be used during write and read servo data SR to be used during read are recorded in this order in each servo area. During write, the read write control unit starts the write head recording data at the timing when reading write servo data SW from the servo area is completed.

A chimeric, non-human animal can be produced by a method that entails providing a microcell that contains one or more foreign chromosomes or fragment(s) thereof and then fusing the microcell with a pluripotent cell, thereby introducing the foreign chromosome(s) or fragment(s) into the latter. The pluripotent cell thus obtained can be used to generate a chimeric, non-human animal, the cells, tissues, and/or progeny of which can be the source of a product, such as an antibody, that is associated with one or more genes on the foreign chromosome(s) or fragment(s).

In a camera having a camera body unit constituted by combining a plurality of units, the camera configuration is realized so as to allow to easily remove only a lens frame unit from the camera body unit before the other units (for example, a strobe unit, a finder unit, a film feed unit and the like) when the camera is disassembled to repair or replace the lens frame unit by constituting so that the lens frame unit having a photographing optical system can be mounted independently.

A process for producing an electrochemical capacitor including an organic electrolytic solution and electrode bodies immersed in the organic electrolytic solution, each comprising a polarizing electrode (composed mainly of a carbon material containing a partially oxidized, graphite-like microcrystalline carbon), a separator and a collector, in which capacitor each polarizing electrode gives rise to volume expansion when charged and volume contraction when discharged, is provided. The process includes: a step of placing each electrode body and the organic electrolytic solution in a cell container to form a unit cell, a step of placing the unit cell or a cell integrate obtained by electrically connecting a plurality of such unit cells, in a first capacitor container to constitute a first electrochemical capacitor, a step of subjecting the first electrochemical capacitor to charging-discharging cycles until the maximum value of the stress caused by the volume expansion of each polarizing electrode during charging becomes almost constant, and a step of transferring, after the maximum value of the stress has become almost constant, the unit cell or the cell integrate into a second capacitor container to constitute a second electrochemical capacitor. The process can provide an electrochemical capacitor which causes no plastic deformation of the capacitor container and which is superior in durability and reliability.

A lock device includes a frame which has an opening and a fixed portion internally provided therein. A lid member is hinged to the frame, the lid member being rotatable between an open position and a closed position, the opening of the frame being opened by the lid member at the open position and closed by the lid member at the closed position. A lock member locks the lid member to the frame when the lid member is at the closed position, the lock member including a connecting unit and a rotating unit, the connecting unit configured to be connected to the fixed portion so as to lock the lid member to the frame, the rotating unit configured to be engaged with the connecting unit, the rotating unit actuating the connecting unit so as to connect the connecting unit to the fixed portion when the rotating unit is depressed, the rotating unit actuating the connecting unit so as to lock the lid member to the frame when the rotating unit is rotated, wherein the rotation of the rotating unit is allowed by a disengagement of the rotating unit from the connecting unit caused by the depression of the rotating unit.

A pole incorporating solar cells has a lighting device or like electric device attached thereto, and a required number of solar cell modules arranged approximately vertically on at least one portion of peripheral wall of the main body of the pole. The arrangement of solar cell modules has the function of generating the electric energy to be consumed by the electric device for one day, utilizing solar radiation afforded by at least scattered sunlight selected from scattered sunlight or direct sunlight. A storage device is provided in the pole main body and has a capacity to accumulate therein the electric energy to be consumed by the electric device for one day, and is repeatedly charged and discharged every day.

Disclosed is the ink jet head in which a part of the partition wall of the ink manifold 8 is constructed from the flexible damper membrane 9 which absorbs the pressure wave of the ink by being vibrated therethrough, the damper membrane 9 entirely vibrating under the single vibration mode with the same phase and having the natural frequency so as not to produce resonance with the reflected wave, thereby it can avoid that ink ejecting property is influenced by reflection occurring in the retrograde component of the pressure wave and it can obtain uniform ink ejecting property every ejecting time.

A liquid crystal (LC) panel cleaning device of the present invention includes a work table and a terminal seat located above the work table. While the cleaning device is in operation, the terminal seat sustains a terminal portion included in an LC panel against a pressure acting on the terminal portion. The terminal seat is connected to ground. This successfully protects the terminal portion from damage and prevents devices built in the panel from being damaged by static electricity.
