Title: Joining method
Inventor: INOUE KIYOSHI
IPC: B23K28/00
Filed: 1987-02-20
Abstract: PURPOSE:To weld even a thin work with low heat capacity with high accuracy by welding a joining part of the work by the contact and opening discharge by the vibration of welding materials CONSTITUTION:The welding materials 1 are fitted to a spindle 2 of a vibrating reed 3 and provided vibratively in the direction of the axial center by an electromagnet 5 and an exciting coil 6 of a head 4 and the welding materials 1 are in contact with a weld zone of the thin work 15. Then, the head 4 and the work 15 are provided movably vertically in the direction of the axial center by a servomotor 14 and rotatably by a rotation controller 23 respectively. When the exciting coil 6 is excited by an excitation power source 27, the welding materials 1 vibrate in the direction of the axial center and the welding is performed by the pulse discharge by the contact and opening. At that time, since the welding surface is cooled at the time of opening, even thin work with low heat capacity can be welded with high accuracy.

Abstract: PURPOSE:To easily and quickly measure a clearance by providing a plurality of measuring sections the thicknesses of which become thinner toward one end of a gauge main body from the other end in steps through different level sections. CONSTITUTION:A clearance gauge is composed of a long and narrow platy gage main body 2 and, on the main body 2, measuring sections 4A-4D the thicknesses of which become thinner in steps through different level sections 3,... toward one end B of the main body 2 from the other end A. Therefore, each section 4A-4D is formed in a uniform thickness between each level difference 3 and between level differences 3 and ends A and B of the main body 2. In addition, the widths W1-W4 of the sections 4A-4D are also gradually reduced toward the end B from the other end A. At the time of measuring a clearance, the gauge is inserted into the clearance. As a result, one of the level difference sections 3,... comes into contact with the clearance and the thickness of the measuring section 4C on the end B side of the different level section 3 can be regarded as the dimension of the clearance.

Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To cut off ultraviolet rays without deteriorating transparency of a plastics container by molding a plastics material added with a pigment based on specific formulas. SOLUTION: A particularly preferable plastic material to be used is a cycloolefinic polymer and its hydrogenated material. A pigment which is added to the plastic material to control the transmission of ultraviolet rays is shown in the following formulas I-III: 1,1'-[(6-phenyl-1,3,5-triazine-2,4-diyl)diimino]bis-9,10 anthracenedione; 2,2'-[1,2-ethanediyl bis-(oxy-2,1-phenylenazo)]-bis[N-(2,3- dihydro-2-oxo-1H-benzimodazol-5-yl)-3-oxo-butanamide; and N-[4-(amino carbonyl) phenyl]-4-[[1-[(2,3-dihydro-2-oxo-1H-benzimodazol-5-yl)amino]carbonyl- 2-oxo- propyl]azo]benzaimide, or a mixture of these pigments. An amount of each pigment to be used is not particularly limited. However, if an amount is too small, lightproofness (resistance to transmission of ultraviolet rays) becomes insufficient and, if it is too large, coloring becomes deep and, accordingly, visual recognizability of contents in a container becomes difficult.
