Title: Media sheet conveying device
Inventor: IBUCHI YOSHIAKI
IPC: B65H9/20
Filed: 1988-07-20
Abstract: PURPOSE:To prevent improper take-up due to zigzagging of a media sheet and ensure proper quality of images by installing a detector for the detection of zigzagging of a media sheet and issuing a warning according to the result of the detection. CONSTITUTION:If a zigzagging occurs downstream from a pressure transcription section at the left-hand side (rear side), an optical sensor 9a is activated for the detection of the zigzagging. In this case, a motor is turned on and a reversing roller is moved to the right until the optical sensor 9a is deactivated. If a zigzagging occurs downstream from the pressure transcription section at the right-hand side, on optical sensor 9b is deactivated for the detection of the zigzagging. In this case, the motor is turned on and the reversing roller is moved to the left until the optical sensor 9b is activated. In this manner, a zigzagging downstream from the pressure transcription section can be corrected automatically.

Abstract: PURPOSE:To improve the iron loss characteristics of a steel sheet of <=0.25mm thickness without causing deterioration in magnetic flux density by specifying hot finish rolling conditions and process annealing conditions at the time of producing a grain-oriented silicon steel sheet from a slab of silicon-containing steel containing Cu, Se, and Sb by a series of stages. CONSTITUTION:A slab of a silicon-containing steel containing Cu, Se, and Sb as inhibitor-forming components is hot-rolled, and the resulting hot rolled plate is subjected to two-time or more cold rolling while process-annealed between the cold rolling stages under the condition of 50-80% final reduction of area, by which a cold rolled sheet of 0.10-0.25mm final sheet thickness is prepared. This sheet is subjected to decarburizing and primary recrystallization annealing and then to final finish annealing, by which the grain-oriented silicon steel sheet can be obtained. In this method, inlet temp. at hot finish rolling is regulated to 1000-1150 deg.C, and the surface temp. of a work roll in the first stand of a finish rolling mill, just before contact with a stock to be rolled, is regulated to <=100 deg.C. Further, the overall draft at hot finish rolling is regulated to 93-97%, and process annealing is done at 900-1050 deg.C for <=50sec. By this method, an inhibitor, mainly, is precipitated finely and uniformly and magnetic properties can be improved.
