SOLUTION: This point light source LED chip (semiconductor light-emitting chip) 10 includes a support layer 14 rigidly combined with one side of the point light source LED chip 10 while having a recessed hole 46 to optically expose a light transmitting face 42 on the bottom face, and a reflecting mirror 48 formed on the inner peripheral surface of the recessed hole 46 to reflect light entering the inner peripheral surface out of light output from the light transmitting face 42. Thereby, even light slanting at a prescribed angle or larger to an optical axis A is made usable by being reflected by the reflecting mirror 48. For example, light is forced to enter the end face 56 of an optical fiber, and the point light source LED chip 10 highly efficient in using output light can be obtained. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an induction hardening process for forming a quench-hardening layer with a uniform thickness among dihedral angle parts and facial parts in a hexagonal hollow steel rod and the hexagonal hollow steel rod which offers a long drilling life and generates little chipping and bending in use. SOLUTION: In the induction hardening process, the hexagonal hollow steel rod is placed inside an annular high-frequency coil, and the coil and the rod are relatively moved toward their mutual central axes while performing heat quenching. Here, the coil and the rod are positioned apart from each other with their central axes being parallel to each other, and the rod is revolved around its central axis while being heated and quenched. This reduces difference in effective hardening depths between the dihedral angle parts and the facial parts of the rod and yields the rod showing an excellent wear resistance and a high fatigue strength.

摘要： PROBLEM TO BE SOLVED: To provide a shear for an angle, which has not to be replaced every time when a forming size group for angles is changed, can cut the angle by using its common shear, and can try to enhance a production efficiency by cutting the angles. SOLUTION: This invention is concerned with a shear 1 which cuts an angle into a specified length by making use of a lower blade 2 and an upper blade 3 where a plurality of projected parts 5a through 5b and a plurality of recessed parts 11a through 11e are faced to each other so as to be continuous in a hacksaw shape in such a way that both of them are relatively coupled with each other. Each slitting 7 which is connected in a straight line shape with each crest side in such a way that an angle larger than an angle to be rested over the opposite and adjacent parts 5a through 5e, can be rested, is formed in the bottom part 6 of at least one crest side out of the projected parts 5a through 5e of the lower blade 2 on which an angle is rested, and each recessed part 11a through 11e of the upper blade 3 to be coupled with the projected parts 5a through 5e formed with the aforesaid slitting 7, is formed into a size corresponding to each projected part 5a through 5e.

摘要： PURPOSE:To reduce the time required for changing rolls by providing lock means to fix beams on a stand and setting up driving means to move the beams in unfixed state with guides in the direction front and in rear of rolls. CONSTITUTION:One pair of beams 4, 4 are fixed on the mill stand 3 not to shift the position of the guides 6 in the rolling stage by beam lock bolts 5 and beam lock nuts 5a as locking means. Further, the beams 4 are joined with hydraulic cylinders 7 as driving means and set up to enable moving by actuating the cylinder 7 when the lock with the bolts 7 is released. At the time of changing the rolls of the rolling mill 1, the nuts 5a are unfastened to release the lock of the beams 4, the guide 6 and the beams 4 are shifted from the stand 3 by the cylinders 7. By this method, because fitting and detaching works are disused, the time for changing the rolls is reduced.
