≪１級課題 -機械工学-≫【問 1】[0001] The invention relates to cleansing a bathwater heater by using waterpressure of tap water and a cleansing tool.
[0002] Conventional methods of cleansing a bathwater heater have been
limited to removing a diffuser of a bathtub and washing the inside of thebathwater heater by forcing a strong flow of water therein using a gardenhose, washing using commercially available carbonate-based chemicals, orthe like.
[0003] These methods have the following problems.
Forcing in a strong flow of water by using a garden hose does notremove all sludge, and the sludge reaccumulates soon.
The chemicals employed in cleansing are not easy to use, are costly
with each use, and lead to water pollution.
When reheating bathwater while taking a bath in milky bathwater inparticular, sludge audibly spews from the hot-water port, which is a foul andunsanitary situation.
The present invention has been made to eliminate these defects.
[0004] Provided is a stepped resin pipe (1), a nozzle portion (2), and a sponge(3) that serves as a cleaning tool to remove filth and that is disposed on adistal end of the nozzle portion (2). Water pressure of tap water is used tocleanse the bathwater heater. The present invention is a bathwater heatercleansing tool having the above configuration.
【問 2】[0016] Fig. 2 is a plan view for describing a type-1 jig 2a. Fig. 2 is asee-through illustration looking through a jigsaw main unit 1, for detailed
description, showing positional relations among a base plate 1a, a circular
guide 8, a jigsaw blade 10 that is a cutting blade, and the type-1 jig 2a.
[0017] An angled slider 4 that slides over a half-angle, i.e., a 45-degrees lineof a right-angle portion of a board is held on an upper face of the type-1 jig 2a,which is made of metal and is provided with fixing fittings 3 at both ends on
the rear face thereof, such that whether to be fixed by two guide blocks 7provided with retaining screws or to slide is selectable. A distal end portion

5 of the angled slider 4 has an arrow-tip shape, and provided therein is arotational bearing 6 to which is rotatably linked a connecting end of a circle
guide 8 specific to the jigsaw.
[0018] Fig. 3 is a frontal view of the type-1 jig. The fixing fittings 3 support
the board of which a quadrant cut is to be performed on a corner, from therear side at adjacent sides A and B of the right angle portion to be cut. Fig.
3 illustrates the state of linkage of the distal end portion 5, the rotational
bearing 6, and the circular guide 8.
[0019] When placing a board on the type-1 jig 2a, the arrow-tip-shapeddistal end portion 5 of the angled slider 4 is slid to be positioned at a vertex Gof the board, followed by fixing the two screwed fixing fittings 3 as to theboard. Thus, the position of the rotational bearing 6 at the distal end
portion 5 of the angled slider 4 is always at some point on the 45-degrees line
within a slidable region, and accordingly the distance to side A is the same as
the distance to side B, regardless of where the rotational bearing 6 issituated. A side face of the cutting blade 10 of the jigsaw 1 is positioned at a
cutting start position on side A or side B, and the retaining screws of theguide blocks 7 of the angled slider 4 and a retaining screw of a guide block of
the circle guide 8 are locked. In this state, the board is cut by moving thejigsaw to the other side following the turning radius of the circle guide 8,
thereby completing a quadrant cut with a high perfection level in a single
cutting operation.
