A polishing method and a polishing film are provided for automatically performing multi-stage batch polishing on an end surface of a workpiece. An end surface of a workpiece and a polishing plate are moved relative to each other while bringing the end surface of the workpiece into contact with a polishing film of the polishing plate. The end surface is moved in a circular motion with a diameter 2 R relative to the polishing film; the center of the circular motion is moved linearly by a distance S on the polishing film; the polishing film is provided with first, second, and third polishing surfaces; and the polishing film is further provided with cleaning surfaces between the polishing surfaces so that the range of the distance S in which one rotation in the circular motion crosses over different polishing surfaces is reduced, or does not cross over different polishing surfaces.

A relay apparatus includes first and second board modules and a bridge module. The first board module is configured to relay the communications among the plurality of electronic devices, the plurality of electronic devices being connected to the first board module. The second board module is configured to relay the communications among the plurality of electronic devices, the plurality of electronic devices being connected to the second board module. The bridge module is configured to communicatively connect the first board module and the second board module.

Relay apparatus

An effective cooling system is provided by the configuration including: a blower; a first rectifier comprising a first opening that lets a first diversion pass through and a second opening that lets a second diversion divided from airflow pass through downstream a first electronic device; a mixing room that is arranged at a downstream portion of the first rectifier and that mixes the first diversion having passed through the first opening and the second diversion having passed through the second opening; and a second rectifier that is arranged at a downstream portion of the mixing room and includes a third opening and a fourth opening, a mixed airflow of the first diversion and the second diversion passing through the third opening and the fourth opening.

Container for electronic device and relay device

A rack mount device comprising: a housing; first and second drawer sections to be withdrawable from the housing; storage sections provided in the first and second drawer sections, each of storage sections including memory devices; a control module to control the memory devices; a connection cable to couple an external connection terminal of the housing and the control module and include an excess length portion corresponding to movement of the control module; a cable protective tube to be inserted by the excess length portion, one end of the cable protective tube fixed in a vicinity of a connection portion to the control module of the connection cable, another end of the cable protective tube fixed on a bottom plate side of the housing, the cable protective tube including a folded-up section which moves along with the drawing operation; and a cable protective tube deformation device to move the folded-up section.

Rack mount device

A housing apparatus includes a plurality of housing units to have housed objects housed therein, a carrying unit to include the plurality of the housing units arranged in a ring shape, the carrying unit carrying the housing units to a carriage position, and a transferring unit to be disposed facing a carriage destination of the housed objects with the carrying unit existing therebetween to transfer the housed object in the housing unit carried and positioned at the carriage position from the housing unit to the carriage destination or to transfer the housed object in the carriage destination from the carriage destination to the housing unit.

Housing apparatus for housing housed object, housing method therefor, and library apparatus for housing recording medium

A robot hand that does not depend on cartridge types wherein high reliability can be ensured and the size and cost can be reduced with a simple construction. In a library apparatus including a recording and reproducing device for cartridge type media and cartridge accommodating racks, a robot hand is configured to include a hand mechanism including hooks for holding the cartridge and actuators for performing to and fro movement and opening and closing movement of the hooks, and a mounter for pushing the cartridge when the cartridge is inserted into the recording and reproducing device by the hand mechanism, wherein the to and fro movement and the opening and closing movement of the robot hand and the pushing movement of the mounter is performed by one motor. The cartridge is grasped/released efficiently by the movement of the hooks, the actuators and the mounter.

Robot hand for transferring an article in a housing, and a library apparatus equipped with the robot hand for transferring and article stored in a rack

A read/write head for a magnetic tape includes an elongated chip assembly and a tape running surface formed in the longitudinal direction of the chip assembly. A pair of substantially spaced parallel read/write gap lines for supporting read/write elements extend longitudinally along the tape running surface of the chip assembly. Also, at least one groove is formed on the tape running surface on both sides of each of the read/write gap lines and extends substantially parallel to the read/write gap lines.
