  • Patent number: 6751426
    Abstract: In an image forming apparatus in which images are formed on one type of sheets, such as OHP sheets, and at the same time another type of sheets, such as tab sheets, are output and inserted between the former type sheets, the invention makes it possible to avoid the user operation from becoming complicated, to keep users from suffering an increased burden, to provide a desired output result easily handled by the users. To that end, when a storage unit storing tab sheets is designated and the inter-OHP insertion mode is selected, the tab sheets are automatically fed from the storage unit designated by a tab-sheet storage unit designating unit, and are each inserted between OHP sheets.

  • Publication number: 20030026626
    Abstract: An image forming apparatus capable of printing images on tab-sheets as well as on normal sheets can automatically perform a mixed printing job including image printing for the normal sheets and image printing for the tab-sheets. The apparatus makes it possible to use image information a number of times and that preparation of the image information is easy. In the apparatus, image information of a text sheet document to be printed on the text sheets and image information of a tab-sheet document to be printed on the tab-sheet are separately inputted to the apparatus and separately stored in an image memory in advance. The apparatus performs combined printing in which printing of the image information of the text sheet document stored in the image memory and printing of the image information of the tab-sheet document stored in the image memory are so combined that the printings of the pages of the tab-sheet document are inserted intervening in the printing of the text sheet document at designated page positions.

  • Patent number: 6495132
    Abstract: There is provided a method for producing a polypeptide using a recombinant baculovirus according to the present invention, wherein said recombinant baculovirus is constructed by ligating the untranslated region of 21 base pairs as set forth in SEQ ID NO:1 upstream of the lobster tropomyosin coding sequence wherein the level of expression of the polypeptide in the baculovirus is remarkably enhanced. There is also provided the polynucleotide sequence of 21 base pairs as set forth in SEQ ID NO:1 and the transfer vector containing the sequence, the recombinant baculovirus genome containing the sequence and the recombinant baculovirus containing the recombinant baculovirus genome to use in the above method.

  • Publication number: 20020146256
    Abstract: There is provided an image forming apparatus an image forming apparatus that is capable of presetting a tabbed sheet feeding section and the number of divisions of recording sheets by tabbed sheets to make the setting operations easier in a tabbed sheet insert mode and a tabbed sheet producing mode during image formation, thus improving the operability. An image forming section forms images on tabbed sheets each having a tab projecting from one edge thereof. A tabbed sheet print mode setting section sets a tabbed sheet print mode in which an image is formed on the tab of each of the tabbed sheets. A control section enables the tabbed sheet print mode setting section to set the tabbed sheet print mode when a sheet feeding section that stores tabbed sheets and the number of tabbed sheets per set are set in advance.

  • Publication number: 20020075523
    Abstract: In image reading apparatus capable of performing a read-while-feed operation in which an original is read while being fed by an image sensor placed at a fixed position, presence/absence of dust and/or dirt on a platen is detected, and, in a case where dust and/or dirt are detected at all of a plurality of predetermined positions by said detector, the read-while-feed operation is inhibited and the presence of dust and/or dirt is notified to a user. When, removal of dust and/or dirt on the platen is detected in a state that the read-while-feed operation is inhibited, the read-while-feed operation is allowed.

  • Patent number: 4663116
    Abstract: A nuclear reactor is equipped with a cooling water circulation system which includes a water-feed conduit and a drain conduit to circulate the cooling water to and from a pressure vessel which surrounds a reactor core, the cooling water having a free liquid level maintained above the reactor core. The drain conduit is inserted in the pressure vessel from the upper side toward the lower side relative to the free liquid level. A double tube consisting of an inner tube and an outer tube maintaining a gap therebetween is formed in the end portion of the drain conduit. The inner tube and outer tube being continuous with the drain conduit, the opening at the lower end of the inner tube is located below said free liquid level but above the reactor core. The opening at the upper end of the outer tube is located above the free liquid level. The opening at the lower end of said outer tube is located below the reactor core.
