  • Publication number: 20160179432
    Abstract: Each of a plurality of, as many as three or more, processes is executed by one of a first virtual machine and a second virtual machine, and each of the first and second virtual machines executes at least one of the processes. At the execution of each of the processes, a virtual memory unit corresponding to the process is referred to. Based on ranks each assigned in advance to one of the processes, a processor changes an assignment destination of a physical memory area currently assigned to each of virtual memory units, except for a virtual memory unit corresponding to a last-rank process, to a virtual memory unit corresponding to a next-rank process following a process corresponding to a virtual memory unit to which the physical memory area is currently assigned.

  • Patent number: 5529631
    Abstract: A length of sheet material is continuously surface treated, typically modified or coated, by continuously feeding helium gas or a helium gas mixture into a treating chamber while a plasma region is created in the gas under atmospheric pressure, continuously moving a length of sheet material into and out of the chamber through entrance and exit ports to pass through the plasma region, thereby continuously subjecting the sheet at either surface to plasma discharge treatment. The entrance and exit ports are sealed in a less gas tight manner to allow leakage of the helium gas or gas mixture.
