Title: Mechanical plating method
Inventor: KOSHIBA GIICHI
IPC: C23C26/00
Filed: 1988-07-06
Abstract: PURPOSE:To prevent a plating layer formed by mechanical plating from being made ununiform in thickness by carrying out mechanical plating while removing metal chips sticking to the surface of a metal brush with a grindstone or a cutting tool. CONSTITUTION:A metal brush 1 is turned at a high speed and brought into contact with a metal block 2 to tear fine metal chips from the block 2. At the same time, the brush 1 is brought into contact with a material 3 to be plated to mechanically plate the surface of the material 3 with the metal torn from the block 2 through the brush 1. At this time, the remaining metal chips not converted into a plating layer and sticking to the surface of the brush 1 are removed by bringing a grindstone 4 or a cutting tool into contact with the brush 1. The formation of an intensely worked layer in the surface of the block 2 can be prevented and a formed plating layer 5 can be made uniform in thickness even when mechanical plating is continuously carried out.

Abstract: PURPOSE:To attain the structure with small size, light weight and a low posture by short-circuiting a radiation conductor element and a ground conductor at a position where a distance to two corresponding sides of a rectangular radiation conductor element differs and providing a feeding point between the short- circuit conductor and the end side. CONSTITUTION:A dielectric 8 thinner in comparison with a wavelength is clipped by a rectangular radiation conductor element 1 and a ground conductor 7 and the radiation conductor element 1 and the ground conductor 7 are short-circuited by using a short-circuit conductor 6 at a position where a distance to two opposed end sides of the rectangular radiation conductor element 1 differs. Further, a feeder is fitted to two feeding points 4, 41 on the radiation conductor element 1 between the position of the short-circuit conductor 6 and the two end sides. Thus, the radio wave is resonated at a wavelength being nearly equal to four times of the length from the short-circuit conductor 6 to the two end sides. In this case, since the position of the short-circuit part is in common, the resonance is applied with almost no mutual effect.

The hole 5 of the stock 7 is reduced in diameter while the hole is controlled by a mandrel 14, by which the hole is formed as the wire through-hole. The semi-finished product formed in such a manner is ejected from a die hole 9 by a knock-out pin 15 after the punch 13 and the mandrel 14 are returned to the hole position. A wrench engaging face 6 is formed to the lower side of a cylinder hole 19 by the die having a hole 20 for forming the wrench engaging face conforming to the shape of the wrench hole of a box wrench. The top end part of the molding is then lathed to form external screw threads 3 for mounting, by which the contact tip 1 is obtd. Since the stock is subjected to work hardening, the contact tip formed in such a manner has the longer life against the wear by the welding wire passing in the wire through-hole.

IPC: A61L9/20
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To sufficiently lengthen a life of a lamp retainer material as well as to efficiently light an electrodeless discharge lamp held and closed within a protector tube, etc. SOLUTION: An electrodeless discharge lamp is vertically held and closed within a protector tube 4. When an induction coil 2 is supplied with a high-frequency current from a source 10 through leads 7, a light emitting tube 1 is lighted, ultraviolet rays are emitted, which penetrate the protector tube 4 and are irradiated to the surrounding water, then pasteurize the water. A mercury- pool 3 in which mercury 20 is held protrudes from the light emitting tube 1. For example, when a load of the tube wall of the lamp is 0.38 W/cm<2> the temperature of the mercury 20 can be controlled at 40 deg.C and the electrodeless discharge lamp can be efficiently lighted if the projecting length L of the mercury-pool 3 is set for 40 mm.  Also because gaseous nitrogen 30 is filled within the protector tube 4, ozone does not generate, for that, a lamp retainer material does not deteriorate and its life can be lengthened.
