To provide a forming device and a forming method capable of suppressing a reduction in strength of a formed material and of forming a flange part having a desired thickness. At least one of an upper die (12) and a lower die (11) that are paired each other is moved in a direction in which the dies are combined together to form a main cavity part (MC) and a sub-cavity part (SC) communicating with the main cavity part (MC), and a gas is supplied into a metal pipe material between the upper die (12) and the lower die (11) to form a pipe part (100a) of a metal pipe (100) and a flange part (100b) of the metal pipe (100) in the main cavity part (MC) and the sub-cavity part (SC), respectively. Furthermore, by controlling a flange forming member (94) by the controller, the flange forming member (94) is allowed to advance in the sub-cavity part (SC), the formed flange part (100b) is crushed, and thus a flange part (100c) adjusted to be made thin is formed.


A method for manufacturing a semiconductor element, including forming a metal film, which contains at least one metal selected from the group consisting of titanium, tungsten, molybdenum, and chromium, on a first surface of a substrate formed of silicon carbide, and forming a metal silicide film by causing a silicide reaction within an interface between the substrate and the metal film by irradiating the metal film with a pulsed laser beam having a wavelength within a range of 330 nm to 370 nm.

A shovel 1 includes a lower traveling body 2, an upper rotating body 3, an excavating attachment including a boom 4 and an arm 5, a controller 30, an engine 11, and a hydraulic pump 10 that is driven by the engine 11 and discharges hydraulic oil to drive the attachment. The controller 30 obtains a hydraulic load applied to the attachment and calculates an engine speed command at predetermined time intervals based on the obtained hydraulic load. The engine speed command is increased as the hydraulic load increases. Also, the engine speed command reaches the maximal value at substantially the same time as the hydraulic load reaches the maximum value.
