Abstract: In a three-dimensional shaping method and a three-dimensional shaping apparatus, a shaping path of each of a plurality of layers includes an inner shaping path and outer shaping path for shaping an inner wall portion and outer wall portion that surround a space and are adjacent in an inward-outward direction. The progression directions of the inner shaping path and outer shaping path are the same direction.

Abstract: In a three dimensional shaping method and a three dimensional shaping apparatus, when a three dimensional object is obtained by laminating a resin material having thermoplasticity, the resin material is melted, and the melted resin material is laminated in a chamber to form resin layers. Next, the pressure in the chamber is adjusted to maintain the temperature of each of the resin layers within a predetermined temperature range in the chamber.

Abstract: A device capable of improving quality of welding by improving estimation precision of coating removal completion of a conductor which is an ultrasonic welding target is provided. An ultrasonic vibration energy (E) of a horn (11) is adjusted based on magnitude of a displacement amount (a reference displacement amount (?Z)) of the horn (11) during at least a partial period of a period from a state in which an FFC and a PCB are interposed by the horn (11) and an anvil (12), through a “first stable state” in which a displacement speed (v) of the horn (11) is stable in a first speed zone in a course in which the displacement speed (v) of the horn (11) increases, until a “second stable state” in which the displacement speed (v) is stable in a second speed zone of a higher speed zone than the first speed zone.

Abstract: A device capable of improving estimation precision of coating removal completion of a conductor which is an ultrasonic welding target is provided. A displacement speed v of the horn (11) is chronologically measured. A progress situation of the melting and removal of an insulating coating C0 (a synthetic resin included in the insulating coating C0) between both conductors C1 and C2 which are welding targets is estimated based on a transition form from a “first stable state” in which the displacement speed v is stable in a first speed zone to a “second stable state” in which the displacement speed v is stable in a second speed zone of a higher speed zone than the first speed zone in a course in which the displacement speed v of the horn (11) increases.
