Abstract: A kneading state detection device includes an acquisition unit that, when an extrusion molding machine that kneads a raw material or kneads a raw material and an additive is in operation, acquires an output of an AE sensor installed on a housing of the extrusion molding machine, and a determination unit that determines a kneading state of the raw material, based on a comparison between a change in intensity of the output of the AE sensor acquired by the acquisition unit and a threshold.

Abstract: A gap control part controls a clamping device so that mating surfaces in a die face each other across a gap, and thereby a cavity and an external part of the die communicate across the gap. A molten metal feed control part controls a molten metal feed device so as to feed molten metal into a sleeve when the gap is being maintained. An injection control part controls an injection device so as to start a forward movement of a plunger at a time when the gap is maintained and there is the molten metal in the sleeve. A clamping control part controls a clamping device so as to make the mating surfaces abut against each other to eliminate the gap after the forward movement of the plunger is started and before the molten metal reaches a molten metal surface height at which the molten metal flows into the gap.

Abstract: A production device for melt-blown non-woven fabric, with which a high molecular weight polymer can be reduced in molecular weight by applying a shear force to the high molecular weight polymer without adding an additive such as a peroxide that promotes thermal decomposition reaction, and a low molecular weight polymer can be efficiently produced. The low molecular weight polymer and the melt-blown non-woven fabric are produced using a continuous high shearing device that applies a shear force to the high molecular weight polymer serving as a raw material by rotation of a screw body 37 to reduce the molecular weight of the high molecular weight polymer so as to obtain a low molecular weight polymer, and cools the low molecular weight polymer by passing the low molecular weight polymer through a passage 88 arranged in the axial direction inside the screw body 37.

Abstract: In a processing machine 1, an X-axis control unit 33X, in each control cycle Tc, controls the position of an X-axis table 9X in the X-direction by feedback. The Z-axis control unit 33Z, in each control cycle Tc, acquires an up-close detection value of the position of the Z-axis table 9Z in the Z-direction, computes a second deviation based on a difference between the acquired detection value and a target position, and controls a Z-axis drive source 23z so that the second deviation is reduced. The Z-axis control unit 33Z, in each control cycle Tc, acquires an up-close detection value of a first error comprised of a deviation of the X-axis table 9 in the Z-direction, and increases or reduces the second deviation based on the detection value of the first error so that at least a portion of an error in a relative position of a workpiece 103 and a tool 101 in the Z-direction originating from the first error is cancelled by movement of the Z-axis table 9Z in the Z-direction.
