  • Publication number: 20180298489
    Abstract: A vapor deposition method for depositing different vapor deposition materials onto a vapor deposition target provided in a chamber is disclosed. A first vapor deposition material is heated, via a first heater, for a predetermined period for increasing a temperature of the first vapor deposition material. Based on the increased heat, vapor of the first vapor deposition material is ejected from a first vapor deposition source towards the vapor deposition target. After the predetermined period has elapsed and via a second heater, the second vapor deposition material is heated for increasing a temperature of a second vapor deposition material. Based on the increased heat, vapor of the second vapor deposition material is ejected from a second vapor deposition source towards the vapor deposition target. The first vapor deposition material contains an organic functional material, and the second vapor deposition material contains a metal material.

  • Patent number: 9983657
    Abstract: An image processing apparatus is configured to transit to a communicable power-saving state in which information exchange is possible through a network while power supply to a part of units of the apparatus is stopped. The apparatus includes a connection detection unit configured to detect a connection state of a network cable; and a power supply control unit configured to control a supply state of a power source according to the connection state of the network cable. When the network cable is changed from a connected state to a disconnected state, the power supply control unit controls the supply state of the power source so as to cause the apparatus to transit to a connection detectable power-saving state in which a power supply range is more limited than that in the communicable power-saving state and in which detection of the connection state of the network cable is possible by the connection detection unit.
