Abstract: PURPOSE: To easily remove the top of a concrete pile by covering a hollow cylinder on the end portion of the iron bars at the top of the concrete pile.  
     CONSTITUTION: In the assembling work of iron bars, a hollow cylinder 3 is covered on the top portion 1' of the iron bars, and the whole of the iron bars inserted into a bored pit. Then, concrete is placed by an usual method into the bored pit and the top 4 of the concrete pile is exposed by digging out the soil around the top 4 of the concrete pile. Then, plural boreholes are formed in the top 4 of the concrete pile, concrete breakers 7 are then inserted into the boreholes 6, and the breakers 7 are operated to break the top 4 of the concrete pile. Then, foundation is placed on the end 1' as anchor of the iron bars by usual construction method. Thus, the top 4 of the concrete pile can be exactly broken by a comparatively weak force, making construction work easier and safer.

IPC: H01C17/28
Filed: 1992-03-04
Abstract: PURPOSE:To adjust the peeling strength between plating layers by controlling the adsorption amount of catalyst adsorbed onto the plating layers formed by non-electrolytic plating treatment. CONSTITUTION:After roughening the surface of a ceramic element assembly 1 by ammonium hydrogen fluoride, the first non-electroly-tic nickel plating layer 2 is formed by successively immersing said element assembly 1 in tin chloride solution (sensitizer), palladium chloride solution (activator) and non- electrolytic nickel plating solution. Next, said element assembly 1 is repeatedly immersed in the first two solutions. At this time, the immersion time of the palladium chloride solution (activator) is adjusted by the release strength (a) between the non-electroly-tic layers. Next, after the immersion in the non- electrolytic plating solution and the formation of the second nickel plating layer 2, a solder plating layer 3 is formed by electroplating treatment on the layer 2. Through these procedures, the activator treatment (immersion) time (b) can be adjusted to control the catalyst adsorption amount onto the non- electrolytic plated layer 2 thereby enabling the peeling strength between the non-electrolytic plated layers to be increased up to specific value.
