Title: Pump
Inventor: SAITOU MASAHIRO
IPC: F04D7/06
Filed: 1979-04-27
Abstract: PURPOSE: To raise the anti-corrosive property by applying iron plating of 10μm or more in thickness on to the surface of an impeller and a casing made of copper slloy, being kept in touch with cooling water, of a pump sending the cooling water, including seawater and industrial water, and thereby preventing the electrical corrosion.  
     CONSTITUTION: Iron plating 7 about 10μm or more thick is applied on to the surfaces of a bronze-phosphate impeller 2 and a bronze-phosphate casing 1 of a pump. This plating has excellent adhesiveness even against the seawater of high flowing speed such as 15m/sec. and so is effective for corrosion. As another trouble, gap corrosion is liable to occur on a stainless-steel impeller shaft 6 in a gap between the impeller 2 and the casing 1. In this case, application of iron plating 7 to the impeller 2 and the casing 1 provides the electrical anticorrosion, since the iron plating 7 is base in relation to the impeller shaft 6. As for pipings made of carbon steel connected with a sucking port 4 and a discharge port 5, similar application is also effective for preventing the electrical corrosion.

Title: Method for removing coolant of boring tool
Inventor: SASAKI YASUO
IPC: B28D1/04
Filed: 1990-03-02
Abstract: PURPOSE:To prevent working surface from being stained by coolant over a wide area and a share point part from being heated by heat of cutting by a method wherein the coolant poured on a cutting edge is acceleratedly vaporized so as to bore without staining a surface to be machined with heat source. CONSTITUTION:When a cutting edge 9 is brought close to concrete 39, firstly, an elastic body 28 contacts the surface of the concrete 39. At that time, by opening a cock 36 properly, fluid is poured on the cutting edge 9. By pressing a boring tool 1 further, the elastic body 28 is compressed and deformed, resulting in bringing the cutting edge 9 into contact with the concrete 39 in order to start boring. At this time, the elastic body 28 develops sealing properties by the energizing force of a compression spring 26 so as to prevent fluid from escaping outside a heat generating body 25, which generates high temperature heat so as to accelerate the vaporization of chloro fluorocarbon 225, resulting in preventing concrete 3b surface from being stained by liquid mud. Since cooling liquid is vaporized by means of heat source, which accelerates the vaporization of the liquid, no staining of floor surface and the like occurs and the cooling effect of the cutting edge of a bit 10 can be enhanced.
