Abstract: PURPOSE:To reduce center and side elongations and to improve product yield by detecting a sheet shape in the lateral direction of a rolled stock, comparing the shape with a target value to find shape errors, separating the error into low-order components and high-order components and controlling cooling liquid spraying amounts. CONSTITUTION:A shape detector 9 is installed in the outlet side of a rolled stock 2 rolled by a rolling mill 1 to detect tensions in respective regions in the width direction of the stock 2 and detected tensions are outputted to a subtracter 11. A target shape is previously inputted to the subtracter 11, so that a difference between an actual shape and the target shape is found and the difference is divided into low-order components, such as 2nd and 4th orders and high-order components higher than those orders. Low-order components are inputted into an each zone flow rate command output device 17 to control a cooling liquid spraying amount from three groups of nozzles for a zone coolant 5 to reduce low-order errors. High-order components are inputted to a high-order component error spot coolant output device 19 to control a coolant spraying amount from respective nozzles for a spot coolant 7 to reduce high-order errors. Center and edge elongations and complex errors and controlled with high accuracy.

Abstract: PURPOSE:To perform the high-speed changeover of a frequency at all using temperatures by changing the offset voltage of a control voltage applied to a voltage controlled oscillator corresponding to an ambient temperature in a temperature variable offset type amplifier circuit. CONSTITUTION:When the fluctuation of the temperature is generated at the time of the same control voltage by the temperature characteristics of the voltage controlled oscillator 1, the fluctuation of an output frequency is generated. Then, in the temperature variable offset type amplifier circuit 8, input from an offsetting circuit 7 worked so as to cancel frequency fluctuation for temperature fluctuation from initial setting by an element (thermister, for instance) for which the fluctuation of characteristics is generated corresponding to the temperature present in the input part of the output of the offsetting circuit 7 is inputted to an amplifier part, amplified and added with the output of a phase detector 5 and the control voltage corresponding to the temperature fluctuation is outputted. Then, by the control voltage outputted from the temperature variable offset type amplifier circuit 8, the voltage controlled oscillator 1 is set at the output frequency for which the temperature characteristics are corrected, that is a desired frequency, when a loop at the time of frequency changeover is open.

Abstract: PURPOSE:For preventing the transmission loss of laser beam from increasing when a beam waveguide of a laser machining system is bent, to make said light waveguide of a flexible pipe of which a reflector made of a material for efficiently reflecting laser beam is fitted on the inside. CONSTITUTION:The beam waveguide 11 of a laser machining system is made of a flexible pipe 11a of which a reflector 22b is fitted on the inside.
