Title: Picture quality stabilizing method for image reader
Inventor: OKUMURA TOMOHIRO
IPC: H04N1/04
Filed: 1991-04-30
Abstract: PURPOSE:To improve the start-up characteristics of a linear light source by performing preliminary illumination according to an illumination time determined according to the photodetection level right after illumination and a photodetection level which is a specific time later or/and its variation rate. CONSTITUTION:When a fluorescent lamp 1 is powered ON to illuminate, an A/D converting circuit 12 checks the digital output of a CCD 6 right after the illumination and stores its peak level Pa in the RAM in a control circuit 16. Then the output of the CCD 6 is checked again the specific time DELTAt later and its peak level Pb is stored. After the variation rate DELTAP is calculated by a CPU from the Pa and Pb, the illumination time DELTAty, interval frequency N, and interval T are found from the RAM and interval control is performed according to the data. When a read start signal is inputted during this period, the Pa, Pb, and DELTAP are found again to set a preliminary illumination time DELTAtchi up to when reference temperature is reached, and reading operation is started after DELTAtchi.

Filed: 1993-05-28
Abstract: PURPOSE:To prevent an unexpected trouble from being happened and stabilize the operation by arranging a group of rolls at the downstream side of a continuous forging device and immediately straightening the warp of a cast slab developed at the time of forging the cast slab in a continuous casting apparatus for metal. CONSTITUTION:Pinch rollers 4 with three steps of pressure cylinders are arranged at the downstream side of the continuous forging device 3 to straighten the warp developed at the time of forging. The pressure cylinder fitted to each roll is made to have so sufficient force as to be able to straighten when the warp is developed. In the three step pinch rollers 4, side rolls 5 are arranged to each to straighten the warp in the side parts, too. For example, a slab having the cross sectional size of 400X560mm is produced with the continuous casting and the continuous forging device 3 is positioned at 26m from the meniscus of molten steel. The casting speed is made to be 0.50 (m/min) and the rolling reduction is made to be 60 (mm) and three sets of the pinch rolls for straightening are arranged at the downstream side of the forging device. By this method, the warp of the cast slab 2 can perfectly be straightened.

Title: Recording device and method
Inventor: NIIKURA TAKEJI
IPC: B41J2/07
Filed: 1993-05-28
Abstract: PURPOSE:To correct the slippage of a recording caused by the warpage of a recording paper. CONSTITUTION:When the recording is done on one sheet of recording paper, a recording paper 1 is lifted from a platen 34 at the area wherein the recording is performed by a head 9, and in response to the lifting quantity, a recording element at the upper end of the head 9 slips from the recording element at the lower end. For this reason, the slippage is converted into a scanning time of the head 9, and the recording timing at the upper end of the head is delayed so that the value may become 0. It is taken that the quantity of slippage between the upper end and lower end linearly transits and the recording timing at each recording element is corrected.
