摘要： A laser marking apparatus is provided with a laser emission unit that emits laser beam and a laser radiation unit that is detachably connected to the laser emission unit. The laser radiation unit radiates the laser beam emitted from the laser emission unit toward an object to be processed. A projection, which projects rearward, is formed on a part of the laser radiation unit that is connected with the laser emission unit. A recess is provided in a part of the laser emission unit that is connected with the laser radiation unit. The projection can fit into the recess. The recess is opened forward, backward, to lateral sides, and downward.

摘要： An input circuit for an apparatus for measuring an electric signal having a measuring section to measure an electric signal. An input signal path for outputting an input signal to be measured from an input terminal to the output side has a composite buffer amplifier connected to the output side. The composite buffer amplifier includes a high frequency amplifying circuit which amplifies a high frequency signal component of the input signal, a first switch whose input is selectively connected to one of the output of the input signal path and a ground level, a low frequency amplifying circuit which is connected to an output of the first switch and amplifies a low frequency signal component of an output signal from the first switch, an addition point for adding the output of the high frequency amplifying circuit and the output of the low frequency amplifying circuit and for outputting to the measuring section of the utilizing apparatus, a negative feedback circuit for negative-feeding back the output of the addition point to the input side of the first switch, and a second switch, interlocked with the first switch, for selectively shutting off the power source voltage that is supplied to the high frequency amplifying circuit while maintaining the high frequency amplifying circuit operative.

摘要： Controlling for obtaining the aimed strip shape using a rolling mill provided with rolls, which are variable in amount of crown by feeding a pressurized oil in the inside. In addition, the rolling mill is provided with right and left pressing-down balancers and roll benders. The strip shape in the width direction of the strip is detected, the detected shape being approximated by a function including terms of the first, second, fourth, sixth or eighth power of a variable, which is a position or a distance in the width direction of the strip, the amount of pressing-down of the right and left pressing-down balancers being adjusted to coincide the term of the first power with the aimed value thereof, the amount of crown of the roll being adjusted to coincide the term of the second power with the aimed value thereof, and a roll bending force being adjusted to coincide the term of the fourth, sixth or eighth power with the aimed value thereof.
