Abstract: PURPOSE:To reduce the quantity of consumption of a contact and the number of weldings by interposing both layers of an nonoxidized Ag alloy and Ag having the same component as Ag-oxide contact material as intermediate layers between the Ag-oxide contact material and Cu (alloy). CONSTITUTION:The nonoxidized composition Ag alloy having good jointability, namely, the Ag alloy having the same component as the Ag-oxide material is subjected to thermocompression bonding to the Ag-oxide material formed by dispersing an oxide of Cd, Sn, Sb, In, Zn, etc., in Ag to form a first material. Ag is subjected to thermocompression bonding to Cu (alloy) to form a second material. The above-mentioned first material is held for a prescribed time at the temperature below the melting point of both and above 400 deg.C in a nonoxidized atmosphere of N2, etc., or an inert atmosphere to accelerate diffusion of the joined interface. The first material is then joined to the second material so that the Ag alloy layer and the Ag layer are made to the intermediate layers to form composite material. By this method, the quantity of consumption of a switch is reduced and the number of weldings is diminished to zero and the contact where peeling is also not observed at all is obtained.

Title: Control method for grinder grinding robot
Inventor: OKI NOBUAKI
IPC: B24B27/00
Filed: 1989-12-27
Abstract: PURPOSE:To prevent the lock state by decelerating the feed of a grinder by a robot when the load current becomes lower than the rated current. CONSTITUTION:When the load current value rises to exceed the upper limit value after the feed of a grinder 2 is decelerated to the low-speed feed, an upper limit-over signal (b) is output from an overload detector 9 to a sequencer 10, and a stop command (e) is again output. Since the stop command (e) is output to stop the feed of the grinder 2 when the load current exceeds the upper limit value, the lock state can be prevented, and such a trouble as the breakage of the grindstone 2 does not occur. When the load current becomes lower than the rated current, a deceleration command (f) is output, the grinder 2 is fed at a low speed without stopping its feed. The efficient grinding work can be performed near the rated current.
