  • Publication number: 20110274852
    Abstract: Disclosed is a method which enables stable and high-speed deposition of a diamond-like carbon film by plasma CVD using a general-purpose vacuum chamber without needing significant modification of the apparatus. Specifically, the method forms a diamond-like carbon film on a substrate by plasma CVD, in which the diamond-like carbon film is formed by applying a bipolar pulsed direct-current voltage to the substrate, feeding a toluene-containing gas to the chamber, and controlling the total gas pressure in the chamber at 4 Pa or more and 7 Pa or less.

  • Patent number: 7984315
    Abstract: An external storage device includes a media control section (10), a monitoring section (20), an interface section (30) and a power control section (40). The media control section (10) drives a recording media and performs data access to the recording media. The monitoring section (20) monitors whether the data access by the media control section (10) can be performed or not. The interface section (30) performs communication with a host device. When the monitoring section (20) detects that the data access can not be performed, the power control section (40) limits power supply to the interface section (30). When the monitoring section (20) detects that the data access can be performed, the power control section (40) re-starts the power supply.
