  • Publication number: 20200013593
    Abstract: In a film-forming technology using charged particles, a disturbance in film thickness distribution caused by leakage magnetic field is suppressed. A film-forming method embodies a technological idea of switching generation and stop of a magnetic field during a film-forming operation so as to stop the generation of the magnetic field during a period when plasma is generated and generate the magnetic field during a period when plasma is not generated.

  • Publication number: 20200006706
    Abstract: A method of manufacturing a display apparatus having an organic EL element includes: a step of forming the organic EL element over a substrate made of a flexible substrate; and a step of forming a protecting film 16 made of an inorganic insulating material so as to cover the organic EL element by using an ALD method. In the step of forming the protecting film 16, the protecting film 16 is formed by alternately performing a step of forming a high-density layer 16H by using an ALD method and a step of forming, by using an ALD method, a low-density layer 16L that has the same constituent element as the high-density layer 16H and has a lower density than the high-density layer 16H. The protecting film 16 has a layered structure made of one or more high-density layers 16H and one or more low-density layers 16L so that the low-density layer 16L and the high-density layer 16H are alternately layered so as to be in contact with each other.

  • Patent number: 10449447
    Abstract: A non-limiting example game system comprises a server and a plurality of game apparatuses, each game apparatus emulating a game program. If applying a predetermined instruction during a game, a game screen is captured and an image file is produced. Furthermore, at this time, emulator status information is uploaded to the server from a game apparatus. Then, the server transmits a URL indicative of a storing location of the emulator status information to the game apparatus. The game apparatus writes the URL as metadata of the image file, and uploads the image file to the server. Furthermore, the game apparatus downloads a desired image file from the server, and downloads the emulator status information according to the URL that is acquired from the downloaded image file. An emulator status of another game apparatus can be reproduced by reading this emulator state information.
