A reducing mill includes a plurality of stands disposed along a rolling direction line. The stands each include n rolls (n&#x2267;3) disposed around the rolling direction line, the n rolls are shifted by 180&#xb0;/n around the rolling direction line from n rolls included in a preceding stand. The n rolls included in each of the stands excluding the last stand each have a groove having an arch shape. The bottom of the groove has a circular arc shape around the rolling direction line having a first radius in cross section. The distance between the surface of a roll flange portion between the bottom and the edge of the groove and the rolling direction line is longer than the first radius. The distance between the edge of the groove and the rolling direction line is longer than the first radius in the groove of a roll included in the preceding stand.

The plug is for expanding the inside diameter of the end portion of a metal pipe. Its cross section is a circle, and includes a taper portion and a parallel portion connected to the tail end of the taper portion. The diameter of the taper portion gradually increases from the head end of the taper portion to the tail end of the taper portion where the diameter is D. The axial distance LR from the point where the diameter D=D&#xd7;0.99 to the tail end where the diameter is Dsatisfies the Expression 22&#x2266;LR/((D&#x2212;D)/2)&#x2266;115. The taper angle on the surface where the diameter is Dis larger than or equal to the taper angle on the tail surface of the taper portion following the point where the diameter is D. The diameter of the parallel portion is D

A die through hole has an inside surface including a bell portion, an approach portion, and a bearing portion from the entrance side. The diameter of the approach portion is Don its entrance side and Don its exit side and gradually decreases from the entrance side to the exit side. The diameter satisfies Equation (1): 0.7&#x2266;D/D&#x3c;0.97. The die half angle of an inside surface where the diameter Dis D/0.97 is not less than the die half angle Rof an inside surface nearer to the approach portion exit side than the inside surface where the diameter is D. The axial distance LR from the inside surface where the diameter is Dto the inside surface where the diameter is Dsatisfies Equation (2): 20&#x2266;LR/((D&#x2212;D)/2)&#x2266;115. The through hole diameter at the bearing portion is fixed at D, and the length is LB and satisfies Equation (3): 0.3&#x2266;LB/D&#x2266;10.

An electric washing machine according to the present invention performs a washing process for washing laundry without the use of a detergent by generating water streams in an outer tub () containing an electrolyzed liquid produced through electrolysis by an electrolyzing device () when a zero detergent course is selected by a user. The electrolyzing device () is provided as a water treatment unit () attached to a lower portion of an outer side surface () of the outer tub (), and includes a thin-box-shaped electrolyzing chamber (), a pair of electrodes () supported at opposite edges thereof, and a pair of water communication paths (). The pair of water communication paths () are disposed in a vertically juxtaposed relation to connect the outer tub () to the electrolyzing chamber () with the intervention of packings (). Thus, an assembling operation and the like can conveniently be performed, and water can efficiently be electrolyzed for use in the washing process.

A clothes drier according to the present invention can minimize failures in a sensor and can satisfactorily detect drying processing irrespective of the environment. In the clothes drier, an atmospheric temperature sensor 44L for detecting the substrate temperature required to determine the termination of the drying processing is disposed outside a circulating duct 18 and is mounted on a control substrate 42 having a thermal capacity on which a microcomputer for controlling operations performed by the clothes drier is mounted. Since the sensor 44L is provided outside the circulating duct 18, the sensor 44L is less affected by dust and water, as compared with a case where it is provided inside the circulating duct 18.
