Filed: 1984-08-14
Abstract: PURPOSE:To prevent a variation of a plate thickness of a strip end part by measuring a tension of a metallic strip before and behind a stand, and adjusting a rolling reduction of the stand based on a forward rate derived from its measured value. CONSTITUTION:Tension measuring devices 1a, 1b are provided before and behind a stand (i), and also an operator 2 for calculating a forward rate from its measured value is provided in the vicinity of the stand (i). A tension of a strip of the entry and the delivery of the stand (i) is measured by the tension measuring devices 1a, 1b, and its measured value is inputted to an operator 2. In this case, when the strip is bitten to the next stand from the stand (i), the operator 2 calculates a variation quantity of the forward rate by adding a data of a setting device 3 to each tension measured value. Subsequently, an operator 4 corrects a rolling reduction quantity based on the variation quantity of the forward rate, and adjusts a roll interval. According to this method, a variation of a plate thickness of a strip end part is suppressed and prevented.

Title: Picture editing device
Inventor: YAMASHITA TAKETOSHI
IPC: G06F17/21
Filed: 1988-07-08
Abstract: PURPOSE:To edit pictures at a high speed by changing the writing position of a pattern based on a position changing instruction and the position designation. CONSTITUTION:A picture constitution reading means 3 reads successively the picture constitution information 1 out of a picture constitution memory means 2 and a deciding means 4 decides the type of the information 1. If the information 1 is equal to a graphic identifier, a selection means 7 selects a graphic writing means 5. The means 5 reads the graphic information 8 out of a graphic memory means 9 based on the graphic identifier and writes the information 8 into a picture memory means 11. In case the information 1 is identical to a position changing instruction, the means 7 selects a writing position changing means 6 and this means 6 changes the writing position based on the position designation corresponding to the position changing instruction. Thus the writing position instruction is simplified for patterns and the pictures can be edited at a high speed.
