An induction heating coil according to the present disclosure includes a pair of arcuate pipes curved in an arcuate shape along a circumferential direction of an outer peripheral surface of a cylindrical object to be heated, and a straight pipe connecting one ends of the arcuate pipes to each other, in which at least one wall is formed inside the straight pipe, the at least one wall extending along a longitudinal direction of the straight pipe and dividing an internal path of the straight pipe into a plurality of paths, and at least one rhombic through holes is formed in the wall.

Induction heating coil and its manufacturing method

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.

Crash box and its manufacturing method

A laser drilling method is a laser drilling method for performing drilling on a workpiece by use of a laser beam. The laser drilling method includes, after machining a through hole by radiating the laser beam to the workpiece (S), scanning with the laser beam centered around the through hole toward a radial direction while changing a radiation output of the laser beam (S).

In a fuel injection valve having a nozzle hole plate wherein a nozzle hole is formed, the nozzle hole is formed with a flow path cross-section having an oval shape that has long axes and short axes, and the nozzle hole is formed having a tapered shape in which a flow path sectional area becomes larger from an entry-side open end portion toward an exit-side open end portion. The nozzle hole is formed such that a second angle that is an intersecting angle of opposing nozzle hole inner wall surface portions in an oblique section along the short axes of the entry-side open end portion and the exit-side open end portion, is greater than a first angle that is an intersecting angle of opposing nozzle hole inner wall surface portions in a longitudinal section along the long axes of the entry-side open end portion and the exit-side open end portion.
