Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To suppress plate width variation to a minimum by predicting temp. variation at skid mark, etc., beforehand and changing responsiveness of plate width control. SOLUTION: At the beginning, temp. variation in the longitudinal direction of a material to be rolled is directly measured by a thermometer or is indirectly estimated while replacing with rolling load variation at an edger, etc., resulting from hardness variation due to temp. variation of skid mark, etc. That is, plate width external disturbance produced between stands due to a temp. variation factor in the rolling direction of rolling material is predicted beforehand by extracting from frequency analysis. By using this predicted value, gain correction of a controller for tension control by looper operation between stands, which is a representative plate width control means, is executed. By this method, responsiveness of tension control is changed corresponding to a size of plate width external disturbance, thus, stabilized plate width control is made possible.

Title: Electronic component mounting method
Inventor: YAMAMOTO MINORU
IPC: H05K13/08
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent a failure board from being sent to a subsequent process by detecting the position of a board prior to electronic component mounting and that after the electronic component mounting, comparing the detected positions, and detecting the mounting deviation clue to the positional deviation of the board during mounting operation. SOLUTION: Prior to mounting a component 3, the positional deviation quantities of the actual position 9b of a recognition mark 9 from its correct position 9a, i.e., ΔXa and ΔYa, are measured. Then, the component 3 is mounted by correcting the position by the measured positional deviation quantities, and the components 3 are successively mounted at the actual positions of an electrode 10. When mounting operation to a board 4 is completed, the position of the recognition mark 9 is remeasured, is compared with the position 9b measured prior to the mounting operation, and when the positional deviation exceeds a fixed quantity that causes mounting failure, a control part is instructed to give the alarm to the operator to inform the operator that the workpiece is a failure board.  Thus, even when a failure board is manufactured by not mounting the component at the correct position due to the positional deviation of the board during mounting operation, the failure board is prevented from being sent to the subsequent process.
