    Abstract: 1. A plasticizing device includes a barrel including a resin material supply port portion and a fiber supply port portion which is formed on a distal side from the resin material supply port portion; and a screw that comprises a shaft body and a flight, and is received in the barrel. The barrel is disposed with a posture in which its axial line intersects a gravitational direction. A maximum length of an opening in the barrel of the fiber supply port portion along an axial direction of the barrel is 1 time or more and 2 times or less as much as a pitch of the flight disposed in a portion of the screw which faces the opening in the barrel of the fiber supply port portion in a direction perpendicular to the axial line of the barrel.

    Abstract: A run-around circuit makes a hydraulic fluid discharged from a rod-side chamber along with a forward movement of a piston in an injection cylinder flow into a head-side chamber. A servo valve is provided in the run-around circuit and is connected to a tank. In a first state, the servo valve permits flow from the rod-side chamber to the head-side chamber, while prohibits flow from the rod-side chamber to the tank. In a second state, the servo valve prohibits flow from the rod-side chamber to the head-side chamber, while permits flow from the rod-side chamber to the tank. The servo valve can control the flow rate of the hydraulic fluid discharged from the rod-side chamber in each of the first state and second state.

    Abstract: An injection molding machine pass/fail determination system includes: a monitoring data extraction module that extracts non-defective article monitoring data and defective article monitoring data from basic data in which a pass/fail determination result on a molded article formed by an injection molding machine is associated with monitoring data; a high-influence monitoring data extraction module that extracts high-influence monitoring data having a high influence on a defect type from among the extracted monitoring data; a molding parameter calculation module that calculates a molding parameter being a parameter to be used when pass/fail determination of the molded article during molding performed by the injection molding machine is performed based on the monitoring data of the same type as the high-influence monitoring data; and a pass/fail determination module that compares the molding parameter with a determination threshold being a threshold for the molding parameter and determines whether a defective article has occurred.

    Abstract: A workpiece machining device includes a positional deviation correction unit configured to correct a positional deviation of a radius end mill by detecting a positional deviation between a real contour line and an ideal contour line of the radius end mill. The positional deviation correction unit calculates a first correction value configured to make a center of a first arc section formed into an arc shape at a corner portion of the ideal contour line and a center of a second arc section formed into an arc shape at a corner portion of the real contour line to be identical to each other in a plane perpendicular to the rotational axis, and corrects a machining point by the radius end mill using the first correction value.
