摘要： PROBLEM TO BE SOLVED: To carry out highly reliable, inexpensive welding connection excellent in workability. SOLUTION: Ends of cable conductors 1 each formed of a stranded wire or a solid wire are heated by carrying a current while holding and pressing them with a pair of welding electrodes so as to integrally form each of them into a flat plate shape, and the flat plate-like ends 1a, 1a of both the cable conductors 1, 1 are overlapped on each other and thereafter, the flat plate-like ends 1a, 1a are welded to each other by carrying a current by holding them with a pair of welding electrodes. Thereby, the cable conductors 1, 1 can be welded to each other without using a terminal board.

摘要： PROBLEM TO BE SOLVED: To equalize a pressurized load during pressurization by electrode rods and to improve a heat balance. SOLUTION: This energizing welding connecting connector has a terminal plate 3, which is held between a pair of electrode rods 5, 6 together with an electric wire conductor 2 and to which the electric wire conductor 2 is welded and connected via energization to the electrode rods 5, 6. In this case, a metal plate 4 is interposed between the electrode rod 5 and the electric wire conductor 2 on the side opposite to the terminal plate 3. Since the metal plate 4 is interposed between the electrode rod 5 and the electric wire conductor 2 directly abutting against each other in prior art, a pressurized load or a contact resistance can be equalized and an energization path becomes symmetric, thereby improving positioning property and heat balance. Breaking strength at a connected portion is also enhanced and stability is improved.

摘要： PROBLEM TO BE SOLVED: To obtain the optical transmission body which has excellent bending capacity transmission characteristic even though the diameter of a core is larger than a specific value, by forming the core with the composition of cross-linking polymer and low molecular bodies. SOLUTION: The optical transmission body consists of a core 1, which is made of the organic material that is transparent and has a certain optical refractive index, and a clad 2, which is provided on the outer peripheral of the core 1 and is made of the organic material having a low refractive index. The core 1 is formed from the composition of cross-linking polymer and low molecular bodies. To maintain good optical and the heat resistance characteristics of the clad 2, it is desirable to use polytetrafluoroethylene and tetrafluoroethylene/hexafluoropropylene double common polymerized bodies. It is also desirable to select the range of an outer diameter ϕof the core 1 to be within 3 to 30 mm. If the core diameter is less than 3 mm, no difference in the bending capacities is obtained between the optical transmission body above and the synthetic resin optical transmission body made by coating the peripheral of a conventional synthetic resin core with the clad of fluorinated resin. If the diameter of the core 1 becomes more than 30 mm, the bending capability is greatly reduced.

摘要： PROBLEM TO BE SOLVED: To make a liquid phase plating member invade into a gap between a conduc tor and a terminal so as to accelerate diffusion and decrease the gap, and increase reliability in junction strength, by connecting the terminal, on which a low melting point metal similar to the plated element wire or its stranded wire is plated, to the plated element wire or its stranded wire, which is provided by plating a copper or copper alloy or their compound wire with a metal having a lower melting point than such composite material, by heating the plated element wire or its stranded wire and the terminal under a pressurized condition. SOLUTION: As a plating material, tin, silver or a metal of its lower melting point than these is used, heating due to electric conductive heating or use of a heating metal jig, light beam, or a heat source of a semiconductor laser or connection due to a load of ultrasound as its substitute is preferable. Tin is fused by heating diffusion when bonded to a copper-based material, connection strength is further increased, and corrosion proof of a welding part is further improved by electrochemical action as an anode. A method for electrically conducting and heating under pressurization at a current of 2 to 4 KA after welding a tin-plated stranded wire and a tin-plated metal terminal to the tin-plated copper element wire or its stranded wire is preferable. Water or air not enter the junction part.

摘要： PROBLEM TO BE SOLVED: To provide a light guide unit having small unevenness of projection light. SOLUTION: The light guide unit 1 is formed by fitting an optical member 5 which has its surface roughened is fitted to one end of a light guide 4 equipped with a transparent columnar core 2 and a clad 3 which covers the core 2 and has a less refractive index than the core 2 and when the light from a light source 7 is made incident on the other end of the light guide unit 1 through an optical fiber 6, part of the incident light is transmitted through the optical member 5 while the rest is irregularly reflected by the optical member 5. Consequently, the projection light from the light guide unit 1 is scattered and can be reduced in unevenness almost without decreasing the illuminance of the whole projection light.

摘要： PROBLEM TO BE SOLVED: To suppress insensitive part in an end part to the minimum and provide a pressure sensitive sensor cable with improved water-proofness, reliability of sensor functions. SOLUTION: While being kept so as not to touch each other, two detection lines 5, 6 are spirally arranged in the inner circumference of an elastic insulating material 1 and at the cable terminal part 3, the lines 5, 6 are U-turned in the inverse directions while being kept from each other and the U-turned detection line 5 and detection line 6 are again spirally arranged in the inner circumference of the elastic insulating material 1 while being kept not touching each other. In this case, the cable terminal part 3 is formed into a semi-spherical body from the same resin as the elastic insulating member 1 and at the same time, a gap 7 is kept between those two detection lines 5, 6 to bury the detection lines 5, 6 in the insulating resin.
