Latest Patents

Kaminaka's latest patents include a computer system and a storage volume management method, as well as a computer-readable storage medium. The computer system comprises a storage apparatus, a host computer, and a copy control program. This system performs copy operations of volumes allocated to a guest operating system (OS) of the host computer. The copy control program obtains volume information of the guest OS from a virtual machine (VM) control program at a specified time. It then compares this information with previous volume information of the guest OS and executes volume copy control based on the comparison results. This innovative process ensures appropriate copy operations, even when the association between the guest OS and volumes changes during system operation.

Another significant patent involves a plasma display device and a plasma display panel drive method. This invention addresses the issue of error displays that can arise from changes in discharge characteristics during the reset period, particularly after prolonged operation. In this plasma display device, the slope of a slope waveform in the reset period is adjusted according to the operation time of the device. The configuration of the slope waveform includes a stepwise plurality of slopes within a predetermined reset period. For instance, as the operation time increases, the rising and falling slope waveforms of the reset waveform are configured in two steps, with the first slope becoming steeper and the second slope gentler than before the change.
