Abstract: PROBLEM TO BE SOLVED: To achieve a stable contact of a decorated member with an opposed surface by a method wherein a bar-shaped or bandshaped elastic member is branched off in two directions in the course of the length thereof within the same plane and end parts at both the branched parts are bent along a surface vertical to a plane to mount a keeper member on both the bent end parts. SOLUTION: An elastic member of an hairpin 10 is made up of a Y-shaped spring steel and the end parts 2 of the Y-shaped branched parts 1 are bent in shape. A V-shaped end part of a V-shaped decorated member 12 is mounted at the two bent end parts 2 and the decorated member 12 is used as keeper member to pinch hair between the member and the elastic member 11. The Y-shaped elastic member 11 is previously formed to warp to the side opposed to the decorated member so that the elasticity thereof works on the hair when it is pinched. Thus, as the elastic member 11 is shaped in the form of Y and the mounting position of the decorated member 12 is set at two Y-shaped branched end parts 2, the elastic member 11 is kept from oscillating along the width of the surface of the opposed decorated member 12 and can securely pinch the hair stably.

Abstract: PURPOSE: To safely disassemble and to remove checker bricks without allowing broken pieces and dust scatter to the outside by piercing an opening on the side opposite from the partition wall in the lower part of a hot stove, and exploding explosive compounds within the vent holes of the bricks.  
     CONSTITUTION: An opening part 6 is pierced in a shell 4 on the side opposite from a partition wall 9 above the receiving plate 8 in the lower part of a hot stove 2. Thence, explosive compounds are loaded in the vent holes of lower checker bricks 12 and the vent holes of upper checker bricks 13, respectively. If the bricks 12, 13 are explosively broken by exploding said explosive compounds, the vent holes annihilate and cavities are formed. At the same time, the broken brick 12 parts are automatically discharged through the part 6 by explosive forces. Further, the bricks 13 fall into the cavity parts, and repeat collision with each other, by which they are segmented to small pieces and are automatically flowed away from the part 6. According to this method, the disassembling work is accomplished instantaneously without damaging the shell 4.
