Abstract: A learning device, for constructing a learning model for generating a prior acceleration command value for controlling a control target in advance of the time a load on a boiler used for thermal power generation changes, includes: a learner configured to generate the learning model by mechanically learning, as learning data, a data set including a power generation command value for the thermal power generation and the prior acceleration command value which have been used in a previous operation of the boiler.

Abstract: A roof panel (31) is pre-set on the left and right side members (4) fixed to an underbody of a car. A roof panel spot welding station (7) includes a pair of frames (34) and two joisted-locating jigs (35, 36) bridging the frames. Each of the joisted-locating jigs is furnished with a clamp mechanism for holding the roof panel. The roof panel is located to the side members by the locating jigs, and spot-welded to the side members.

Abstract: Each of a pair of side members (4) is located relative to an underbody (3) using two locators (16). Each locator is lowered by a lifter (15) and placed on a slide base (18). The slide base is movable along a slide guide (17) toward and away from a transfer conveyor (11).
