  • Patent number: 7005284
    Abstract: Attempts are made to provide a novel transaldolase gene; a polypeptide encoded by this gene; a recombinant DNA obtained by integrating this gene; a microorganism carrying this recombinant DNA; and a process for producing an aromatic amino acid, an aromatic vitamin, L-histidine, riboflavin, a nucleic acid, a nucleic acid-associated substance, a novel saccharide, etc. by using the above microorganism. As the results of extensive studies, a novel transaldolase gene is isolated from chromosomal DNA of a microorganism belonging to the genus Corynebacterium as a DNA fragment complementary to the requirement for shikimic acid of a transketolase defective variant obtained as a variant with the requirement for shikimic acid belonging to the genus Corynebacterium. Further, a recombinant DNA containing this gene is constructed and transferred into a host microorganism, thereby achieving the objects as described above.

  • Publication number: 20040105450
    Abstract: An image captured by a camera can be sent to and stored in a controller on a LAN as well as to a high-capacity camera with more memory than other camera devices on the LAN and to a camera on another LAN. This allows captured images to be recorded without losing the images even if an irregular event is detected and an irregularity takes place in the camera device at the site.

  • Publication number: 20040105019
    Abstract: A camera equipment includes a first coder for compression-coding a picked-up image for transmission to a network and a second coder for compression-coding the image to store it in a recorder. Even when data cannot be transmitted due to the conditions of a transmission path, the compressed image data can be acquired without fail. The compressed image data before and after an abnormality can be recorded and transmitted in high image quality, and a compression scheme suitable for the expansion decoding scheme at the transmission destination can be selected. The image data generated in a camera unit is compression-coded in according to the expansion decoding scheme at the transmission destination, and transmitted to a network. The same image data thus generated is compression-coded by the second coder using a compression coding scheme in a more finely detailed fashion than that by the first coder.
