  • Publication number: 20050079980
    Abstract: A superconducting cable includes: a cable core having a superconducting conductor; a thermal insulation pipe accommodating the cable core and functioning as a forward path of a coolant channel; and a coolant return pipe disposed beside the cable core in the thermal insulation pipe and functioning as a backward path of the coolant channel. A coolant is passed through a space formed between the thermal insulation pipe and the cable core/the coolant return pipe, and cools the cable core and the coolant return pipe. The coolant that has cooled the cable core, etc., returns through the coolant return pipe. Thus, the heat loss of a coolant in the superconducting cable can be minimized, and the space needed for coolant piping can be made compact.

  • Patent number: 5987166
    Abstract: It is an object to provide an image processing apparatus which can obtain an image reproduction that accurately corresponds to an original color when an ordinary color original is read and which can obtain an accurate marker edition result when a marker original is read. When a color scanning mode to read the color image is selected, an original ground removal by a prescan is not performed. When a marker edition scanning mode to read the marker original is selected, the original ground removal is executed. Thus, a color reproduction which accurately corresponds to the original is executed in the color scanning mode. In the marker edition scanning mode, the color recognition of the marker color is accurately performed without being influenced by the ground color.

  • Patent number: 5974171
    Abstract: An image processing apparatus prevents the misdetermination of a read color and allows correct marker edition. A marker registration circuit reads and register color data marked by a predetermined color marker and a color determination circuit compares the color data registered and the read color data at the reading of the document sheet to determine a color code of the marker color. An area determination circuit determines whether an area being read belongs to a normal area, a line area or a paint area and an output color determination circuit determines a color to be outputted in accordance with the color code and the area being read.
