Abstract: A size of an agitating mechanism can be reduced. An agitating mechanism according to an aspect of the present disclosure is an agitating mechanism for agitating fluid flowing through inside a pipe, including: a rotary body placed inside the pipe so as to be able to rotate in a circumferential direction of an inner circumferential surface of the pipe; and a regulation part configured to regulate a movement of the rotary body in a longitudinal direction of the pipe. The rotary body includes a hollow part penetrating the pipe in the longitudinal direction of the pipe and an agitating blade provided in the hollow part.

Abstract: A method for manufacturing a nanocrystalline alloy ribbon piece with high productivity is provided. The method according to the present disclosure is a method for manufacturing an alloy ribbon piece obtained by crystallizing an amorphous alloy ribbon piece, and includes: preparing the amorphous alloy ribbon piece; sequentially heating the ribbon piece from one end to an intermediate position toward another end to a temperature range equal to or more than a crystallization starting temperature, and stopping the heating when heating the ribbon piece up to the intermediate position; and sequentially heating the ribbon piece from the other end to a position immediately before the intermediate position to the temperature range. In the sequentially heating the ribbon piece from the other end, the ribbon piece is heated up to the position immediately before the intermediate position after the heating is stopped in sequentially heating the ribbon piece from the one end.

Abstract: An arm of a coil segment having an approximate U shape is placed in a slot of a stator core, and a portion protruding from the slot is bent in a circumferential direction. An arm is bent in a direction of an arrow A, and another arm positioned at an inner side in the radial direction in relation to this arm is bent in a direction of an arrow B. The arm positioned at the outer side has at least a part of a bending inner side surface of a bent portion hardened by pressurization.

Abstract: There is provided a method for manufacturing an alloy ribbon that suppresses a different magnetic properties at each position of the alloy ribbon obtained by crystallizing an amorphous alloy ribbon. The method for manufacturing an alloy ribbon includes: heating a laminated body in which positions of thick portions of a plurality of amorphous alloy ribbons are shifted to a first temperature range less than a crystallization starting temperature; and heating an end portion in a lamination direction of the laminated body to a second temperature range equal to or more than the crystallization starting temperature after the heating the laminated body. An ambient temperature is held after the heating the laminated body such that the laminated body is maintained within a temperature range in which the laminated body can be crystallized by heating the end portion to the second temperature range. Q1+Q2+Q3≥Q4 is satisfied.

Abstract: A crash box capable of easily deforming into a bellows shape and absorbing impact energy more reliably, and its manufacturing method are provided. The present disclosure is applied to a crash box which is partly deformed in an axial direction to absorb impact energy when the crash box receives an impact in the axial direction. A first layer made of metal and a second layer made of metal containing a larger volume of bubbles than that of the first layer are alternately formed in the axial direction in the crash box according to the present disclosure.
