A multi-screw kneader that exhibits an extensional flow function before and behind small holes of a disk-shaped segment having the small holes and a method for producing a nano-composite using the multi-screw kneader and a disk-shaped segment to be used therein. The multi-screw kneader includes a plurality of kneading screws and a disk-shaped segment in a barrel. The disk-shaped segment partitions the inside of the barrel downstream a part for charging a kneading material and includes a plurality of shaft penetrating parts through which rotating shafts of the kneading screws rotatably pass and a large number of small holes punched in a periphery of these shaft penetrating parts and serving as flow channels of the kneading material. The nano-composite production includes charging nanoparticles as a resin additive using the multi-screw kneader. The disk-shaped segment includes the shaft penetrating parts and the large number of the small holes.

A computer program causing a computer to execute processing of detecting an abnormality of an industrial machine having a movable part is provided. The computer executes the processing oft acquiring physical quantity data on a time-series basis output from a sensor detecting a physical quantity related to a motion of the movable part; converting the physical quantity data on a time-series basis acquired to a time-series data image representing the physical quantity data; inputting the time-series data image converted to a learning model to calculate a feature of the time-series data image, the learning model being trained with a feature of the time-series data image related to the movable part in a normal condition; and determining a presence or an absence of an abnormality of the industrial machine based on the calculated feature.

A multi-screw kneader is configured to exhibit an extensional flow function before and behind holes of a disk-shaped segment and a method for producing a nano-composite uses the multi-screw kneader. The multi-screw kneader includes a plurality of kneading screws and the disk-shaped segment in a barrel. The disk-shaped segment partitions the inside of the barrel downstream of a part for supplying a kneading material and includes shaft receiving parts through which rotating shafts of the kneading screws are to rotatably pass and the holes are defined in a periphery of the shaft penetrating parts and are configured to serve as flow channels of the kneading material. The method for producing the nano-composite includes charging nanoparticles as a resin additive using the multi-screw kneader.

An extruder including a housing, a first material inlet for a mixture at least consisting of a solvent and a dissolved medium, a material outlet, a screw, a screw drive, and at least one distillation region between the inlet and the outlet, which allows an outflow of solvent, and a discharge line for the solvent.

A treatment element for treating material by means of a screw machine comprises a conveying section and a melting section. The melting section is arranged downstream of the conveying section in a conveying direction and is connected in one piece with the conveying section. This reduces wear and increases the service life.

A kneader has a rotational conveyance member configured to knead the kneading material and convey the kneading material from an inlet toward an outlet by a rotational motion around an axis. The rotational conveyance member has a kneading zone configured to knead the kneading material, a first conveyance zone placed on an upstream side relative to the kneading zone and configured to convey the kneading material, and a second conveyance zone placed on a downstream side relative to the kneading zone and configured to convey the kneading material, and a conveyance force of the second conveyance zone is smaller than a conveyance force of the first conveyance zone in a case where the same conveyance object is conveyed.

A continuous kneading device including a pair of kneading rotors, capable of increasing mesh between the kneading rotors while also suppressing a kneading load applied to the kneading rotors. The continuous kneading device including a barrel and a pair of kneading rotors housed in the barrel. The kneading rotors rotate in mesh in directions different from each other. Each kneading rotor includes a plurality of kneading flights for kneading a material supplied into the barrel. The material is fed axially from the upstream kneading section to the downstream kneading section to be sequentially kneaded. The kneading flight constituting the downstream kneading section has a rotational outer diameter larger than a rotational outer diameter of the kneading flight constituting the upstream kneading section.
