Title: Method and apparatus for controlling take-up machine of steckel mill
Inventor: UEKANE YOSHIHIRO
IPC: B21C47/26
Filed: 1987-12-25
Abstract: PURPOSE:To prevent a rolled steel material from sagging or from receiving excessive tension in time of winding even when a rolling condition is changed by changing the control of a take-up machine from a speed control to a tension control based on a fixed target tension. CONSTITUTION:When an end of a rolled steel material 3 is pushed into the slit 7b of a mandrel 6b which stops and waits at a prescribed slit setting position to output a starting command to the mandrel, a gate 29b is opened by the command, a speed command is guided from a command device 25 of a multiplier 31b, a draft 32b is multiplied here and a pattern command is inputted to a Leonard controller 24 through a gate 33b. The speed of a DC motor 22b is controlled there, the speed of rotation of the mandrel 6b is elevated toward a prescribed starting time speed set over the speed of the rolling mill. Besides, the speed pattern is accelerated at a fixed rate from the starting up to the starting time speed and keeps the starting time speed till a fixed angle of rotation of the mandrel 6b and then is reduced down to the rolling speed.

Title: Electronic sewing machine
Inventor: YOKOMIZO YASUHISA
IPC: D05B19/14
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To provide an electronic sewing machine capable of forming a stitch of high quality when shifting from normal sewing to ending stop sewing. SOLUTION: Stitches are formed in cloth by cooperation of a needle moved up and down by a main motor for rotating a spindle and a cloth feeder having cloth feed teeth, which is projected out and sunk from and under a throat plate in relation to the vertical movement of the needle to feed a cloth piece. Stitches of a zigzag pattern are formed by oscillating the needle in the direction intersecting perpendicularly to the cloth feed direction. When shifting from normal zigzag pattern to the ending stop sewing pattern, even if the normal zigzag pattern is ended in the midway P', stop sewing is started at the turn-back needle position P of the zigzag pattern. By this arrangement, disturbance between the normal zigzag pattern and the ending stop sewing pattern is reduced so as to form stitches of high quality and with beauty.
