Title: Heat insulating ladle
Inventor: TATENO MASAO
IPC: F27B14/08
Filed: 1980-03-19
Abstract: PURPOSE:To reheat the molten metals in plural pieces of ladles with one induction heating furnace by removing the lower half part of a heat insulating material on the outer side of a crucible and inserting the lower half part of the crucible into an induction heating coil. CONSTITUTION:The outer sides of the upper and lower half parts of a crucible 11 are enclosed by upper, lower half part heat insulators 12, 13 respectively, and it is possible to remove the latter from the lower half part of the crucible by removing the bolts and nuts coupling the flanges of both. Also, it is possible to insert the lower half part of the crucible 11 into a separately provided heating oil 32 by lifting the crucible 11 and the heat insulator 12 in one piece. Hence, if the temp. of the molten metal 22 in the crucible 11 lowers down to the temp. below an operating condition, it is reheated in the coil 32, and when it rises up to specified temp., the crucible is lifted from the coil 32, and the heat insulator 12 is immediately mounted to the lower half part of the crucible 11, and is coupled to the heat insulator 12.

IPC: B60G9/04
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To reduce the maximum generating stress without being accompanied with the increase in size and weight, and improve the durability by setting the thickness of both ring arms so as to be small on the anti-torsion bar side, compared with the torsion bar side and have a part thinner than this thickness, and gently changing the thickness of each part. SOLUTION: Each other end of lower ring arms 8, 9 is supported on a frame through brackets 5, 6 and bushes 11, 12 in such a manner as to be mainly vertically rockable. The lower ring arms 8, 9 are formed of plate spring members relatively high in rigidity in vertical direction and relatively easily deflectable in lateral direction. Compared with the torsion bar 10-side thickness, the anti- torsion bar 10-side thickness is small, and a further thin part is formed in a position closer to the anti-torsion bar 10 side between the both. The thickness of each part is gently changed. According to this, the stress concentration to each part can be prevented to reduce the maximum generating stress, and the durability can be improved.

Title: Beam annealing method
Inventor: HASEGAWA MICHIHIKO
IPC: H01L21/20
Filed: 1986-02-20
Abstract: PURPOSE:To enable a single crystal region to be widely enlarged, by making energy-ray beams having band-shaped radiation regions be incident slantingly on a recessed reflection plane shaped in parabola so that the reflected beams are sweep-radiated on the semiconductor layer which is molten to be recrystalized. CONSTITUTION:Laser beams 3a emitted from a light source 11 are reflected on an oscillating reflector 12 to become band-shaped beams 3b, and then reflected on a recessed plane reflector 20 to become crescent beams 3c which are focused only in their width direction. The crescent beams 3c irradiate the radiation part 4 of the semiconductor layer 2 at the position where they pass through a focusing point 13 and become specify in width. The recessed-plane reflector 20 is equipped with a band- shaped recessed reflection plane 21 whose sectional plane is shaped in parabola. When the band-shaped beams 3b are made incident slantingly on the recessed reflection plane 21, the reflected beams become crescent in their sectional shape, forming the crescent beams 3c which focus on the focusing point 13 only in their width direction. Thus, a molten shape in the radiation part 4 becomes crescent, and energy of the beams 3c, with which the radiation part 4 is irradiated, becomes nearly equal to that of the beams 3a, greatly enlarging the width of a recrystalized region 5.

SOLUTION: A porous material having, for example, compressive strength >=5 kg/cm<2> , tensile strength >=2 kg/cm<2> and ductility >=50% is temporarily fastened to one joint surface of precast culver 5, so as to form an annular shape surrounding a turnnel 5B and, then, a plurality of rows of the precast culverts 5 are arranged in such a state as the joint surfaces kept abutted to each other. Thereafter, the porous material is filled and impregnated with a mixture of a liquid water stopping agent of hydrophilic polymerization setting type having a watertight function, and fine-grain cement for adding mechanical strength such as compression resistance.  The mixture spread throughout in a pre-setting state completely seals a joint, and the polymerization reaction of the water stopping agent and the hydration reaction of the fine-grain cement in the mixture develop, thereby setting the mixture. As a result, a high water stopping function can be maintained at a joint over a long term.
