  • Publication number: 20050181698
    Abstract: A method and an apparatus for manufacturing an image displaying apparatus having a display panel. A first substrate of the display panel on which a phosphor exciter is disposed and a second substrate of the display panel on which phosphors emitting light by the phosphor exciter is provided, are prepared under a vacuum atmosphere. Then, the first and the second substrates are carried in a getter processing chamber or bake processing chamber, and getter processing or bake processing is applied thereto under the vacuum atmosphere. After the processing, the first and the second substrates are carried in a seal processing chamber, where the substrates are heat sealed under the vacuum atmosphere. Thus, reduction of vacuum exhaust time and a high vacuum degree in manufacturing an image displaying apparatus is attained and efficiency of manufacturing is improved.

  • Patent number: 6886087
    Abstract: A semiconductor memory device reliably protects data written once into a non-volatile memory and exhibits high EEPROM data security functionality. The device has a user memory area to which a user can write freely chosen data, and a write-information storage memory area for storing information indicating whether or not data has been written into the user memory area. A control logic circuit analyzes whether to execute a write command from a user and outputs a write-prohibition signal if data is already written into the user memory area. The control logic circuit may include a password authentication circuit for authenticating a user-inputted password by comparing it with a password maintained inside the control logic circuit. The frequency of a changeable clock may be used to perform password authentication.

  • Patent number: 6848961
    Abstract: A method and an apparatus of manufacturing an image displaying apparatus having an electron source substrate and a phosphor substrate. The electron source substrate is provided with an electron emitting element formed by covering with a container and by applying a voltage to an electronic conductor on the substrate. While, the phosphor substrate is provided with a phosphor thereon. The substrates are subjected to a getter processing and to a seal bonding process under a vacuum condition through a processing chamber, to complete an image forming apparatus. An improvement resides in miniaturizing and simplifying operation, and in greater manufacture speed and mass production.
