Title: Seal welding method for spiral tube
Inventor: KISHIKAWA RYOJI
IPC: B23K15/00
Filed: 1988-07-06
Abstract: PURPOSE:To facilitate a welding operation and to obtain a welded joint having high reliability by mounting a backing strip having spiral grooves to the inside surface of a cylinder constituted of a spiral tube and welding the adjacent tube rings to each other by electron beam welding from the outside of the cylinder. CONSTITUTION:The backing strip 3 formed with the spiral grooves 3a of the same shape as the shape of the inside surface of the cylinder constituted of the spiral tube 1 is mounted to the inside surface of the cylinder in tight contact therewith. The circumferential weld zones 2 between the adjacent tube rings 1a of the spiral tube 1 and the backing strip 3 are simultaneously and continuously welded by electron beam welding from the outside of the cylinder. The gaps between the adjacent tube rings 1a of the spiral tube 1 are substantially eliminated in this way and the electron beam welding of the circumferential weld zones 2 between the adjacent tube rings 1a is surely executed. Since the simultaneous seal welding of the tube rings 1a and the backing strip 3 is executed, the control of the welding range of the tube rings 1a is possible.

Filed: 1984-08-11
Abstract: PURPOSE:To attain to enhance the reliability, capacity and assembling workability of a sensor, by forming electrodes to both terminals of a strain-sensitive resistor in a thin film while forming a solder layer on the conductor circuit between electrodes in a thick film form. CONSTITUTION:Four thin film like strain-sensitive resistors 4, each of which is formed by providing a silicon semiconductor to an insulating layer, are formed on a diaphragm 2 to constitute a bridge circuit (two central strain-sensitive resistors at the center receive tensile force and two strain-sensitive resistors at the terminal parts receiving compression force). The thin film like electrode parts 8 comprising nickel formed to both terminal parts of each strain-sensitive resistor includes the electrodes 8a on each strain-sensitive resistor and the conductor circuit part 8b between the electrodes. The thick film like solder layer 10 formed on the electrodes 8a and the conductor circuit part 8b between the electrodes 8a covers the whole of the electrodes and conductor circuits on the bridge circuit. The diaphragm 2 generates strain by pressure from a liquid introducing port 7 and each strain-sensitive resistor on the diaphragm 2 generates the change in electric resistance caused by strain and this change is taken out to the outside as the change in bridge output voltage through a lead wire 6.

Abstract: PURPOSE:To stabilize the length of a tail of a wire by scratching a wire at the second bonding point before a tool after the second bonding with a cutter and cutting it, thereby eliminating the field capillary to approach the clamper to the tool. CONSTITUTION:A tool 10 is lowered to carry out the first bonding, and clamper 13 is opened. Then, the tool 10, the clamper 13 and a cutter 17 are moved to the second bonding point to execute the second bonding. Thereafter, the tool 10 is moved upwardly toward the oblique rear to determine the prescribed tail amount. Then, the cutter 17 scratches the wire 11 after the second bonding, and immediately returns the wire to the original position. Subsequently, the clamper 13 effectively clamps the wire 11 and moves to the oblique upward direction to cut the wire. Then, the tool 10 is moved to the next bonding position and simultaneously the clamper 13 feds the wire 11, thereby enabling the first bonding state.
