Title: Magnetic disk unit
Inventor: ISHII EIJI
IPC: G11B21/22
Filed: 2000-09-28
Abstract: PROBLEM TO BE SOLVED: To stably drive an air latch (an aerodynamic type actuator lock) of a magnetic disk unit by efficiently guiding airflow to the air latch without disturbing airflow among disks. SOLUTION: The air latch is provided outside the magnetic disks. The tip section, which receives airflow of the air latch, is formed shorter than the outer peripheral surface of the disks. When the air latch is released, the airflow receiving section of the air latch is moved toward the direction where airflow passage is constituted for causing airflow from magnetic disk end faces and from a shroud to pass through a portion located away from the magnetic disk, and consequently the air latch can be driven stably, furthermore flutter and electric power consumption are reduced since airflow among the disk is not disturbed.

Title: High purity iron, its production method and high purity iron target
Inventor: UCHIKOSHI MASAHITO
IPC: C23C14/34
Filed: 2000-09-29
Abstract: PROBLEM TO BE SOLVED: To produce high purity iron in which the content of impurities such as copper is reduced, to provide its production method and to provide a high purity iron target. SOLUTION: Iron containing impurities such as copper is dissolved into a solution of hydrochloric acid to prepare an aqueous solution of iron chloride in which the concentration of hydrochloric acid is 0.1 to 6 kmol/m3. Next, iron is charged to the aqueous solution of iron chloride and is stirred while an inert gas is blown therein to convert copper contained in the aqueous solution of iron chloride into univalent ions and further to convert iron into bivalent ions. Successively, the aqueous solution of iron chloride is flowed into a column filled with an anion exchange resin. At this time, univalent copper to ions is adsorbed on the anion exchange resin, but, bivalent iron ions are not adsorbed thereon. Thus, copper can be separated from the aqueous solution of iron chloride.  After that, the aqueous solution of iron chloride is vaporized and dried up, is oxidized and is heated in a hydrogen atmosphere to generate iron.
