A speed control apparatus for a cylinder comprises the cylinder, speed controllers for controlling flow rates of a pressure fluid introduced into and discharged from cylinder chambers, a controller for outputting control signals to the speed controllers, and a sensor for detecting the displacement amount of a piston of the cylinder to transmit a detection signal to the controller. Each of the speed controllers includes a throttle section for controlling the flow rate of the pressure fluid flowing through the fluid passage, and a throttle amount control section for changing the throttle amount at the throttle section on the basis of the control signal transmitted from the controller.

A suck back valve comprises an ON/OFF valve, a suck back mechanism, a first sensor for detecting a displacement amount of a first diaphragm of the ON/OFF valve, and a second sensor for detecting a displacement amount of a second diaphragm corresponding to a suction amount of a coating liquid. The suck back valve further comprises a control unit for feedback-controlling the valve displacement speed of the ON/OFF valve and the suction amount of the coating liquid on the basis of detection signals obtained by the first sensor and the second sensor respectively.

Method and apparatus for bidirectionally oscillating a spot of a laser beam incident upon a workpiece to be processed with the laser beam, wherein the laser beam generated by a laser source is reflected by a movable reflecting mirror which is bidirectionally pivoted about a first axis by an oscillating actuator, so that the reflected laser beam is incident upon the workpiece. The apparatus includes a rotary support member which supports the mirror and the oscillating actuator and which is rotatable about a second axis perpendicular to the first axis, and a rotating actuator for rotating the rotary support member about the second axis during bidirectional oscillation of the spot of the laser beam incident upon the workpiece, to thereby change an oscillating direction of the beam spot.

A steel having excellent formability, fatigue endurance after quenching, low temperature toughness, resistance for hydrogen embrittlement, and corrosion fatigue endurance. A method includes heating a steel slab at 1160° C. to 1320° C., hot-finish-rolling the steel slab at a finisher delivery temperature of 750° C. to 980° C., and then coiling the hot-rolled steel at a coiling temperature of 560° C. to 740° C. after slow cooling for a time of 2 seconds or more to produce a hot-rolled steel strip having a structure in which the ferrite grain diameter df corresponding to a circle is 1.1 μm to less than 1.2 μm and the ferrite volume fraction Vf is 30% to 98%, the steel slab containing 0.18 to 0.29% of C, 0.06 to 0.45% of Si, 0.91 to 1.85% of Mn, 0.019% or less of P, 0.0029% or less of S, 0.015 to 0.075% of sol. Al, 0.0049% or less of N, 0.0049% or less of O, 0.0001 to 0.0029% of B, 0.001 to 0.019% of Nb, 0.001 to 0.029% of Ti, 0.001 to 0.195% of Cr, and 0.001 to 0.195% of Mo so that the carbon equivalent Ceq satisfies a value of 0.4 to less than 0.58, and the total x of multiplying factors including that for B according to Grossmann satisfies a value of 1.2 to less than 1.7.
摘要:
There is provided a high-strength steel tube having excellent chemical conversion treatability and excellent formability and a method for manufacturing the high-strength steel tube. More specifically, in processing a mother steel sheet containing, on the basis of mass percent, 0.05% or more C, more than 0.7% Si, and 0.8% or more Mn into a pipe shape, the sum total of absolute circumferential surface strains each applied in individual process steps of the processing is 5% or more as nominal strain. A welded steel tube thus manufactured using a steel sheet even containing more than 0.7% Si can have excellent chemical conversion treatability without mechanical grinding or chemical pickling treatment.
