Abstract: PURPOSE:To improve the productivity, and also to reduce the cost of equipment by forming a bulge part on superposed plate materials by a cooperation action of a punch and a die, also executing the upsetting by the subsequent operation of the punch, and joining both the plate materials by a single purpose press. CONSTITUTION:When plate materials 34, 35 are superposed up and down and placed on a die 20, and a ram of a press is made descend, a holding plate abuts on the plate materials and they are pressed and fixed. Subsequently, only a punch 14 descends continuously, and the plate materials 34, 35 are bulged into a hole 21 and a groove 22 of the die 20 by a rolling down force. The part corresponding to the groove 22 of a bulge part 36 is left in a state that it remains continued to the plate materials 34, 35, and both sides corresponding to cut edges 23, 23 are cut. Subsequently, a shaft rod 29 is depressed against a spring and abuts on an adjusting screw, the bulge part 36 is upset strongly, and spread in the cut side direction. In this way, the plate materials 34, 35 are joined by overhang parts 39, 40.

Title: Manufacture of nonsintering type cadmium electrode
Inventor: YASUOKA SHIGEKAZU
IPC: H01M4/26
Filed: 1990-09-14
Abstract: PURPOSE:To manufacture an excellent nonsintering type cadmium electrode by carrying out complete charging and discharging or partial charging and discharging in an aqueous alkali solution at low concentration while carrying out hydration treatment in an aqueous alkali solution at high concentration. CONSTITUTION:When a nonsintering type cadmium electrode mainly consisting of cadmium oxide is immersed in an aqueous alkali solution, the cadmium oxide is converted into cadmium hydroxide. In this case, when an aqueous alkali solution with high concentration and low electric conductivity is used, the reaction proceeds slowly and uniform cadmium hydroxide is produced in the whole of the electrode and the swelling ratio becomes small. Meanwhile, chemical can uniformly be carried out for the whole of the electrode by using an aqueous alkali solution with low concentration and high conductivity in the process of charging and discharging for the chemical conversion process and partial charging and discharging and thus a nonsintering type cadmium electrode having good battery properties and small swelling ratio can be manufactured.

Title: Inspection device for leakage from vessel
Inventor: NAGASAWA TOSHIO
IPC: G01M3/20
Filed: 1990-09-14
Abstract: PURPOSE:To use gas as an inspection medium and to quickly seal up the open end of a vessel by sealing up the open end of the vessel by air going from a lower peripheral groove, which is formed on a mandrel, to an upper peripheral groove. CONSTITUTION:The mandrel 41 is covered with the vessel 3. A valve 49 is operated to flow herium to a supply path 46. Since air always flows from a lower peripheral groove 42 to an upper peripheral groove 43 and is discharged through a discharging pipe 55 during this operation, helium does not reach an open end 4 of the vessel 3. When valves 49 and 56 are closed in this state, the pressure of a pressurized air supplying source 52 acts as it is, and the inside of the vessel 3 is kept at this pressure including a helium layer in the vicinity of a close end 23. The state is held for a certain time to measure the extent of leakage of helium by a herium detector 57. After measurement, the value 56 is opened and valves 49 and 53 are operated to send air to supply paths 44 and 46, and helium is completely driven out of the vessel 3.
