Title: Image forming device
Inventor: KUMASHIRO HIDEO
IPC: G03G21/04
Filed: 1992-09-19
Abstract: PURPOSE:To surely prevent forgery by slowing down a picture reproduction speed when a picture is possibly a picture being a picture recording prohibit object to discriminate whether or not the picture is the picture of prohibit object with precision and applying invalidating processing to the picture when the picture is the prohibit object picture. CONSTITUTION:A color masking section extracts a specific color from read picture data, the data are binarized by a binarization section and stored in a bit map memory. Furthermore, picture data for preliminary discrimination stored in a ROM are transferred to a pattern storage RAM, two data are compared by a pattern matching section and gives a discrimination result as to whether or not the both are coincident to a CPU. When the both are coincident, since an original is possibly a banknote, the main discrimination is executed. At first, a read speed of image reader section is set to a slower speed than the usual speed, the processing above is executed similarly to the case of the preliminary discrimination and pattern matching in every direction is executed within a time Tb. When the pattern in the bit map memory is coincident, the original is recognized to be a banknote and invalidating processing is implemented.

Title: Magnetic field type lens device for cathode-ray tube
Inventor: MASATOKI TAMIJI
IPC: H01J29/68
Filed: 1984-12-25
Abstract: PURPOSE:To reduce deviation between the geometric axis and the magnetic axis (magnetic deflection), by furnishing a pair of circular ring form yokes at the unopposed magnetic poles of a pair of circular ring form magnets which are magnetized in the direction of the thickness and placed with the same poles opposed each other. CONSTITUTION:A pair of circular ring form magnets 5A and 5B are magnetized in the direction of the thickness, and are placed with the same poles opposed each other. A pair of circular ring form yokes (made of a soft magnetic material such as a low carbon steel) 17A and 17B are installed at the unopposed magnetic poles of the magnets 5A and 5B respectively, with their peripheral free ends curved to oppose closely. Therefore, the magnetic deviation is reduced, that is, the unevenness of the magnetism over the magnet surfaces is clipped and uniformed, by the saturated magnetic property (hysteresis) of the yokes, and the deviation between the magnetic axis and the geometric axis is reduced accordingly. Moreover, the magnets are magnetic-shielded to the outside. Especially, leakage of magnetic flux is reduced because of the opposed magnetic poles even in the cleared space.
