摘要:
The present invention is intended to provide an image processing apparatus capable of two-color output representation in high accuracy even with a full-colored original. A color original is entered by an input means for prescan, a density distribution with respect to a hue is obtained for each electric signal of color image information, and a characteristic point of the color original image is obtained from the result of the density distribution. The two-color separation means separates a full-colored original to two colors free from the same color representation according to the information of the characteristic point obtained.

A copying apparatus includes a first cassette for stacking recording sheets each having a protruding portion, a second cassette for stacking recording sheets having no protruding portion, a detecting unit for detecting a protruding portion of an original to be copied, and a copy unit for copying an image of an original onto the recording sheet fed from the first cassette in the case where the protruding portion of the original is detected by the detecting unit and for copying the image of the original onto the recording sheet fed from the second cassette in the case where the protruding portion of the original is not detected by the detecting unit.
摘要:
An image processing apparatus includes a processing unit for processing an image signal into which an original document, after being exposed to light, is photoelectrically converted, a compression module for compressing image information processed through the processing unit, a memory for storing image data compressed by the compression module, a control unit for setting a diversity of image processing modes, and a predicting module for predicting an image compression rate used by the compression module. The predicting module predicts the image compression rate of an image after being processed according to the image processing mode set by the control unit.

An original document reading apparatus includes a first control portion for performing a first control wherein documents are transported at a first document interval in the event that a detected occupying capacity is less than a detected unused capacity. The first control portion also performs a second control wherein documents are transported at a second document interval which is greater than the first document interval in the event that the detected occupying capacity exceeds the detected unused capacity. A second control portion continuously activates an exposure portion under the first control, and intermittently activates the exposure portion under the second control.

An exhaust gas purifying catalyst includes: a support that contains at least one element that is selected from the first group that consists of Al, Zr and Ce, at least one element that is selected from the second group that consists of Ag, Mn, Co, Cu and Fe, and Ti; and particles that are composed of a metal or oxide of at least one element that is selected from the third group that consists of Ag, Mn, Co, Cu and Fe and that are deposited on the support. Seventy percent or more of any plurality of measurement points with a diameter of 2 nm on a surface of the support are composed of a composite part that has the at least one element selected from the second group content of 0.5 to 10 mol % and has a Ti content of 0.3 mol % or greater.
摘要:
A data input system including electronic paper and a stylus writing device is disclosed. The electronic paper includes a transparent display substrate on which a number of optically readable code patterns have been formed, the optically readable code patterns representing positional information on a display surface, a rear surface substrate opposing the display substrate, and coloring particles that are enclosed between the display substrate and the rear surface substrate and that are movable by applying an electric or a magnetic field. The electronic paper displays an image due to motion of the particle. The stylus writing device includes a writing head provided at the end of the stylus for writing the image by applying an electric or a magnetic field to the electronic paper by contact and includes an optical reading device for optically reading the code patterns formed on the display surface where the end of the stylus contacts.
摘要:
In an internal combustion engine, inside of an engine exhaust passage, a hydrocarbon feed valve (15) and an exhaust purification catalyst (13) are arranged. The exhaust purification catalyst (13) is comprised of a mixture of a first catalyst in which platinum (51) and a basic layer (52) are carried on alumina (50) and a second catalyst in which rhodium (56) is carried on zirconia (55). The concentration of hydrocarbons which flow into the exhaust purification catalyst (13) is made to vibrate by within a predetermined range of amplitude of a 200 ppm or more and within a predetermined range of period of 5 second or less, whereby the NOx which is contained in exhaust gas is reduced at the exhaust purification catalyst (13).

A laser arc hybrid welding head and method which can form satisfactory beads at high speed are provided. A laser arc hybrid welding head (1) for welding a base material (W), which comprises aluminum steel sheets, by performing laser light irradiation and arc discharge, thereby combining laser welding and arc welding, splits inputted laser light (L0) into two beams, i.e., split laser light beams (L2a and L2b), then irradiates the base material (W) with the split laser light beams (L2a, L2b) while focusing these beams (L2a, L2b) on the base material (W), and also performs coaxial welding by generating an arc (A) from an arc electrode (20) disposed coaxially with the optical axis of the split laser light beams (L2a, L2b). Further, the transfer mode of a welding droplet from the arc electrode (20) is rendered spray transfer.
