  • VACUUM PROCESSING APPARATUS AND OXIDIZING GAS REMOVAL METHOD
    Publication number: 20240087916
    Abstract: A vacuum processing apparatus includes a decompressable process container; a supply port configured to supply, to the process container, an ionic liquid that absorbs an oxidizing gas; and a discharge port configured to discharge the ionic liquid supplied to the process container. A recess is provided at a joint portion between members constituting the process container. The supply port is configured to supply the ionic liquid to the recess, and the discharge port is configured to discharge the ionic liquid supplied to the recess.

  • System and method for data multiplexing
    Patent number: 7672224
    Abstract: To reduce the load on a host for controlling a data doubling. Between a host and two disk subsystems, there is connected a data doubling device. This data doubling device behaves as if it were a unit disk subsystem for the host. The data doubling device doubles a data I/O instruction from the host and issues the doubled data I/O instruction to two disk subsystems. In case either of the disk subsystems becomes faulty, the data doubling device sends the data I/O instruction from the host only to the normal disk subsystem. After the fault recovery, the data doubling device performs a data copy between the disk subsystems.
