Title: Device and method for detecting text data
Inventor: SHIGAKI SATOMI
IPC: G06T7/40
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To detect only the text area from data of a bit map system, in which a text and a graphic coexist, by deciding it to be text data when the number of pixels of the same color continuously exceeds a threshold in one column in the horizontal direction or the vertical direction of counted bit map system data. SOLUTION: When continuity of pixels is noticed, the pixels of same color data (black, for example) continuously appear in a horizontal direction (B). In a non-text image on the other hand, the continuity of pixels having the same color data (dark green, for example) does not appear markedly as compared to a text area. Thus, the text area has a feature that the continuity of the pixels having the same color data in the horizontal direction appears and the non-text area does not have the feature. When the continuity of the pixels of the same color satisfies a prescribed threshold, the detected algorithm of the text decides the area to be the text area.

Title: Image forming device
Inventor: WATANABE JUNJI
IPC: H04N1/10
Filed: 1985-05-20
Abstract: PURPOSE:To shorten an image forming time and to save power consumption in terms of a portable image forming device by forming images at the time of an image pickup means going and coming out and returning the image pickup means to the prescribed position upon completion of all image forming processing when plural images of one original are formed. CONSTITUTION:A mirror 12 and an exposure lamp 11 are supported by a carriage 411, while mirrors 14 and 15 are supported by a carriage 412. Both carriages are guided by guide rails 421 and 422 and can be freely shifted in parallel in directions of arrows (a) and (b). The rotation of a scan motor 33 moves the carriage 411, which causes the carriages 422 to shift. Aft this time, since pulleys 47 and 47 act as a moving block, the speed of the carriage 412 comes to the half that of the carriage 411. At the time of forming an image, the drive of the motor 33 moves an optical system 9 in the (a) direction to scan the original G. When a position detector 51 detects the prescribed position, the motor 33 stops, and images of one screen are formed. Then the motor 33 is reversely rotated to form images in the same manner. Thus plural copies can be obtained without a returning action. After the set number of copies are printed, the optical system 9 returns to its home position.

Filed: 1987-04-30
Abstract: PURPOSE:To enable printing in good image density, by warming ink contained in a print drum and stencil paper in short time by means of warm air fed from a warm air generator arranged close to the outer circumferential face of a print drum. CONSTITUTION:A warm air generator 12 comprising a heater such as an electrical heater or a print heater and a fan is arranged close to the outer circumferential face of a print drum above a paper feed roller 9 in a body cover 1. In early winter morning when the stencil printer is cold, the warm air generator 12 is operated to blow out warm air along the outer circumference of the print drum 2. Warm air fed from the warm air generator 12 convects along the outer circumference of the print drum 2 so as to increase the ambient temperature of the print drum 2 in the body case 1. Consequently, the ink contained in the print drum 2, the screen or the stencil paper 3 is warmed to improve fluidity of the ink thus increasing the density of image. A print having a high image density can be obtained by operating the warm air generator 12 for a short time prior to start of printing.

Further, the resonance frequency of the two resonance circuits 3, 3' and the loop antenna element 1 in total three components is two desired frequencies f1, f2 and the circuit element is decided so that the impedance of input/output terminals 4, 4' tapped down by capacity division of the resonance circuits 3, 3' becomes the input/output impedance of the transmission reception circuit to be connected to them, e.g., 50OMEGA. Thus, in connecting a receiver of the reception frequency f1 to the input/ output terminal 4 of the resonance circuit 3 and the transmitter using the transmission frequency f2 of the resonance circuit 3' respectively, one antenna is used as the shared antenna of the transmission and reception equipment having different frequencies from each other.

Abstract: PURPOSE: To improve stainless steel in weldability and resistance to stress corrosion cracking in high temperature pure water, steel composition is controlled in reference to a ratio of some selected alloy elements such as Cr, Ni, Mo, Nb, Ta, etc.  
     CONSTITUTION: "Intergrain" strain stress corrosion cracks occur, when austenite stainless steel is bent into double-U-letter-shape in high temperature pure water. A composition that overcomes this difficulty comprises: C:up to 0.04%, Si:up  to 2%, Mn:up to 2%, Cr:16 to 22%, Ni:9 to 18%, Mo:1 to 4%, N:up to 1/ (150XC%) 2 %, Nb and/or Ta being in a range such that Nb+1/2Ta becomes 12XC% to 1%, the balance iron and unavoidable impurities. This steel is molten produced in an electric furnace, wherein alloy components thereof are adjusted, bloomed, that-and cold-treated to be made into steel material having desired shape and size and heat treated at a temperature of higher than 1,000°C. The stainless steel thus formed, having complete austenitic structure with extremely fine grains, exhibits remarkably improved resistance to stress corrosion cracking in high temperature water.
