Title: Image reader
Inventor: OGAMICHI TAKASHI
IPC: H04N1/401
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To previously prevent the deterioration of an optical system and the deterioration of quality owing to dust and a scan and to improve picture quality by judging shading correction precision based on picture data of a white reference member which is shading-corrected. SOLUTION: A system control part 21 lights a light source 45, scans a white reference board 44 for obtaining white reference data and stores picture data which is digitally converted in an A/D converter 50 in a line buffer 53 as white reference data. A system control part 21 scans again the white reference board 44 and calculates shading correction precision based on picture data at the time of scanning the white reference board 44. Whether the calculated result exceeds a correction precision judgment level or not is checked. When operated correction precision exceeds the correction judgment level, the system control part 21 judges that appropriate shading correction precision is obtained and shifts a processing to a regular read processing.

Title: Electrophotographic system copying machine and fixing device for printer
Inventor: UKEI SHOJI
IPC: G03G15/20
Filed: 1989-12-20
Abstract: PURPOSE:To prevent an unfixed picture caused by the jumping of the trailing edge of paper from disturbance by arranging a lower roller guide on the tangent of rollers, and making flat the prescribed length of the contact part of the lower surface of the paper and providing the part so as to be on the same line as the tangent of the rollers. CONSTITUTION:In order to prevent the jumping of the trailing edge of the paper 10 of low rigidness, a deformation quantity delta is restricted to be smaller than a fixed value. The deformation quantity delta of the center part of the paper 10 is generated on a side lower than the tangent of the coupling surface of a heat roller 1 and an elastic roller 3. Therefore, the deformation in the shape of relief printing on the lower side can be prevented from generating on the center part by arranging the lower guide 7 on the tangent shown by an alternate long and short line. Namely, since the deformation quantity delta always exists in the area where the trailing edge of the paper 10 does not jump, the jumping of the trailing edge can be prevented even when the paper 10 of low rigidness is used. Thus, since the printing picture disturbance caused by the jumping of the trailing edge can be prevented, a high-definition picture can be obtained and the possibility of the occurence of jamming, etc., is remarkably decreased.

Title: Method for activating alkaline secondary battery
Inventor: ABE HIDETOSHI
IPC: H01M10/28
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To enhance discharge capacity, suppress the rise of battery internal pressure, and hold the battery capacity in the initial capacity over a long period by initially charging the alkaline secondary battery in a specific temperature range. SOLUTION: When an alkaline secondary battery having a paste type nickel electrode containing a divalent Co compound, a separator, a negative electrode and an alkaline electrolyte integrated thereto is initially charged, the initial discharge is performed in a temperature range of 30-80 deg.C. The CoO contained in the paste type nickel electrode can be efficiently oxidized, and a conductive matrix of cobalt oxyhydroxide is uniformly formed on the paste type nickel electrode in stable state, whereby the discharge capacity can be enhanced. Since the conductive matrix never causes an extinguishment or reduction in function even when the battery voltage is reduced to lower the reductive potential of cobalt oxyhydroxide in the nickel electrode, the battery shows a high capacity recovering ratio.
