≪１級課題 –機械工学≫【問 1】[0011]
Also, more and more low-grade coals, such as lignite and subbituminous coal,
have come to be used as fuel in thermal power generation and so forth.
Such low-grade coals have a high water content, and powder of the loose bulk
material 7 tends to become a sludge that readily adheres to the bucket 19.
Accordingly, the above problem of load weight at the distal end of the boom 4,
reduced volume of the bucket 19, and such like problems, are particularly
likely to occur when unloading low-grade coal.
This has led to a
proportionate increase in the frequency of cleaning work necessitated.
[0012]The present applicant has already filed a patent application for a bucket 28(see Fig. 6) with an inner side surface that does not readily allow adhesion ofloose bulk material 7 thereto, to solve the shortcomings of such a
conventional bucket 19. This bucket 28 is disclosed in Patent Document 1.
[0014]
However, despite being extremely good with respect to the point of fluidizing
the loose bulk material 7 therewithin, the bucket 28 disclosed in Patent
Document 1 is formed of non-corrosion-resistant steel plates (wear-resistantsteel plates) and is used in a painted state. Study conducted by the present
inventors has shown that when the paint is stripped off through use overextended periods of time and rusting occurs, the loose bulk material 7 suchas coal and the like will adhere to the rust sites.
[0015]
Also, the bucket 28 needs a corrosion margin to be included in anticipation ofcorrosion, inevitably leading to a proportionate increase in weight. Thus,
there is room for improvement thereof.

【問 2】[0023]
As illustrated in Fig. 1, the present embodiment is configured as follows. A
predetermined amount of hot water that is discharged from an outlet 19 of

the bathtub 1 is discharged by a pump device 12 so as to flow into a
circulation pipe 11. This hot water that is discharged flows into an inlet 6 ofa five-way valve type flow distributor 5. The hot water flowing into the inlet
6 flows out of an outlet 7 and flows into a filter device 2, where filtering
material in the filter device 2 filters the foul hot water, and the hot waterthat has become clean is sent to a heating device 3. After being heated to apredetermined temperature in the heating device 3, the hot water flows outof the heating device 3 into an outlet 8 of the five-way valve type flow
distributor 5. The hot water flowing into the outlet 8 flows out of an outlet 9,
and this hot water is returned into the bathtub 1 through a spout 20 of thebathtub 1.
[0024]
The above configuration is a circulation flow path for hot water whenperforming normal operations. When the filtering material in the filter
device 2 becomes foul and is to be cleansed, the five-way valve type flow
distributor 5 is adjusted so that the hot water circulation flow path is in theopposite direction from that in normal operations. Hot water discharged
from the outlet 19 of the bathtub 1 flows into the inlet 6 of the flow
distributor 5, the hot water flowing into the inlet 6 is discharged from theoutlet 8 and flows into the heating device 3, the hot water discharged fromthe heating device 3 flows into the filter device 2, and the hot water thatflows into the filter device 2 is used to cleanse the filtering material in thefilter device 2. The hot water that has become foul from cleansing thefiltering material flows into the outlet 7 of the flow distributor 5, and the foul
hot water that flows into this outlet 7 is drained out of the circulating warm
bath device from a drain outlet 10 of the flow distributor 5.

1. An additive manufacturing apparatus (100) comprising:a powder material supply device (110) that supplies a powdermaterial (P) to a supply position of a base material (B);a light beam emitting device (120) that emits a light beam (BM) thatmelts the powder material (P) supplied to the supply position;a movement device (M1, M2) that relatively moves the supply
position and an emission position of the light beam (BM) relative to the basematerial (B); anda control device (130) that controls respective operations of thepowder material supply device (110), the light beam emitting device (120),and the movement device (M1, M2), wherein
the additive manufacturing apparatus (100) forms a molten pool(MP) by melting the powder material (P) at a predetermined region of thebase material (B) and forms beads adjacent in a width direction by allowing
the molten pool (MP) to solidify,
the additive manufacturing apparatus (100) comprises a detection
unit (140) that detects a size of the formed molten pool (MP), andthe control device (130) corrects a manufacturing condition whenforming a following one of the beads such that an overlapping amount (L) in
the width direction of a previously formed one and the following one to beformed following the previously formed one of the beads becomes constantbased on the size of the molten pool (MP) obtained from the detection unit
(140) when forming the previously formed one of the beads.
