Title: Shape controlling method for rolled sheet material
Inventor: MATSUMIYA KATSUYUKI
IPC: B21B37/00
Filed: 1979-08-21
Abstract: PURPOSE:To improve the flow rate control for the roll coolant oil, by carrying out the PWM control for controlling the flow rate of the roll coolant oil which is hardly effected by only adjusting the opening of the flow control valve, so as to obtain a pulse flow. CONSTITUTION:When the necessary flow rate of the coolant oil is an intermediate value hardly obtainable by adjusting the opening of the flow control valve of the injection nozzle arranged at an arbitrary point along the roll barrel, the opening adjustment of one of the flow control valves is repeated at a constant period sufficiently shorter than the roll's thermal time constant; hereby, the nozzle output is made to take a pulse wave-form, and the PWM control is carried out so as to equalize the mean value of this pulse wave-form nozzle output to the commanded value. For example, when the first flow control valve 2 delivers much more flow of the coolant oil than the commanded value, the pulse wave-form A possessing the pulse width alpha2 is made depending on the PWM command so as to equalize the mean flow rate as the PWM output to the commanded coolant flow rate alpha. The period T is sufficiently shorter than the roll's thermal time constant, and the coolant flow rate becomes equal to the mean value alpha1 of the pulse wave-form A. Hereby, the distortion of the rolled sheet material is reduced.

Title: Memory releasing method of page printer for punt protection
Inventor: CAMPBELL RUSSELL
IPC: B41J5/30
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To improve the consistency of page print throughput of a printer by providing a step where the spotting showing that the 1st race conditional threshold is adaptive to a band is detected out of the image data on a single page, a step where a pre-rasterized band is formed, etc. SOLUTION: A band (page strip) obtained from the image data on a single pace is analyzed (105), and the necessity of pre-rasterizing is decided for a punt (printer overrun) circuit (110). If the pre-rasterizing is necessary (i.e., the 1st conditional threshold is adaptive), a pre-rasterizing buffer and a compression buffer are assigned (115). Then the band is pre-rasterized and the experiential video image processing time (TR) is measured (120). If the TR is longer than the race time (125), the band is compressed (130) and the original display list is released from a memory (135).
