    摘要: A three-dimensionally laminated object modeling apparatus includes a cylinder configured to store a molten resin, a discharging nozzle that is communicated with the cylinder, and a piston configured to discharge the molten resin from the discharging nozzle by moving in a direction of approaching the discharging nozzle and by pressurizing the molten resin in the cylinder, and models a three-dimensionally modeled object by laminating a resin bead that is the molten resin discharged from the discharging nozzle on a table. It includes a drive device configured to relatively move the discharging nozzle with respect to the table and at least one processor configured to acquire a movement speed of the discharging nozzle and control movement of the piston based on the movement speed of the discharging nozzle.

    摘要: An injection molding machine includes a cylinder that accommodates a molten resin, a discharging nozzle, a piston that discharges the molten resin from the discharging nozzle, and one or more processors configured to execute the following functions. The functions include calculating a target pressure at which a flow rate of the molten resin discharged from the discharging nozzle becomes an indicated flow rate, controlling a pressure of the molten resin in the cylinder such that the pressure becomes the target pressure, acquiring a temperature of the molten resin in the cylinder, and acquiring a pseudo-plastic viscosity corresponding to the temperature of the molten resin. The target pressure is calculated based on the indicated flow rate, the temperature of the molten resin, the pseudo-plastic viscosity, and the size of the discharging nozzle.

    摘要: A manufacturing method for an induction heating coil includes repeating a sequence of bedding metal powder in a layer and forming a metal layer by applying laser beam to a predetermined region of the metal powder bedded in a layer to be fused and solidified; and building an induction heating coil by sequentially building up the metal layers one vertically above another. The induction heating coil is a cross-sectionally quadrangular pipe and surrounded by a pair of curved surfaces in a circular arc shape along a circumferential direction of an outer periphery of a circular columnar object to be heated, and a pair of flat surfaces adjacent to the curved surfaces. The induction heating coil is built such that, of the flat surfaces, a flat surface located vertically above a hollow portion of the pipe makes an angle greater than or equal to a predetermined angle with a horizontal plane.

    摘要: An internal combustion engine includes a cylinder head including an intake port, an exhaust port, a water jacket, an intake valve, an exhaust valve, an intake valve seat, and an exhaust valve seat. The water jacket is positioned between the intake port and the exhaust port. The intake valve includes an intake valve head, and the exhaust valve includes an exhaust valve head. The intake valve contacts an intake valve seat surface of the intake valve seat. The exhaust valve head contacts an exhaust valve seat surface of the exhaust valve seat. The shortest distance between the water jacket and the intake valve seat surface is shorter than the shortest distance between the water jacket and the exhaust valve seat surface.

    摘要: An injection molding machine that contributes to improving the quality of a workpiece is provided. An injection molding machine configured to causes torpedo pistons to be slid in one way to thereby plasticize a resin material supplied to a first space of a cylinder, and causes a molten resin to flow into a second space of the cylinder and causes the torpedo pistons to be slid in the other way to thereby inject the molten resin. The injection molding machine includes pressurizing pistons inserted into the torpedo pistons so that the pressurizing pistons can be slid in such a way that an amount of protrusion of the cylinder into the second space of the cylinder with respect to the torpedo pistons is changed, and energizing means for energizing the pressurizing pistons toward the second space of the cylinder.
