The present invention relates to a butt joint structure of a hard metal for a micro cutting tool and a blank material and a method thereof. More specifically, a micro cutting tool is provided wherein a shank material is formed with a first joint hole and a second joint hole in the section of one side for inserting a blank material formed with a joint protrusion section therein so that the blank material is inserted therein without exposure and fixed by butt joint. In addition, a blank material which can produce a micro drill by machining the shank material and the blank material at a time is provided. According to the present invention, a shank material (20) is formed of any one of S45c and S55c carbon steel/SK and SKS tool steel/SKT and SKD dies steel/SKH and HSS high speed steel/SUS stainless steel/metal powder extrusion shank steel/liquid metal materials. The shank material (20) which has a diameter of 4mm, a length of 33mm, and chamfered corners (C) is machined to form a material-inserting first joint hole (21) in the center of one side surface of a cut surface thereof and a second joint hole (2) is formed in the center of the material-inserting first joint hole (21). A blank material (30) is formed with a joint protrusion section (31) and fixed to one side of the material-inserting first joint hole (21) by welding. In the welding method, the blank material (30) is coated with flux and silver alloy powder and inserted into the material-inserting first joint hole (21). After that, the blank material (30) is heated at a predetermined welding temperature to be molten using high frequency electrical electrodes outside. The portion protruded outside from the blank material (30) is precisely inserted so as to be fixed by welding while the blank material (30) is being molten. The outer diameters of the shank material (20) and the blank material (30) are machined so that the shank material (20) and the blank material (30) are formed to have a diameter of 3.175mm and a length of 38mm.

The present invention relates to a floating-anode microbial fuel cell. More specifically, the present invention relates to a microbial fuel cell having an anaerobic unit, an electrode unit and an outflow unit. In this microbial fuel cell, the electrode unit includes an anode disposed to float horizontally on surface water and a cathode provided horizontally at the bottom of a cathode-reaction tank, and a separating layer for separating the cathode and the anode. The microbial fuel cell is characterised in that the cathode is immersed in, by way of example, a liquid substance containing organic matter and sewage or waste water flowing in a thin fashion horizontally in an anaerobic state, and the anode is formed in such a way that it floats horizontally on the water surface with one of its surfaces in contact with an air layer, while the other surface is in contact with the water layer on the water surface. The microbial fuel cell according to the present invention is advantageous in that it can continuously produce electric power with a high yield from the liquid substance containing organic matter such as sewage or waste water, and it allows the organic matter to be stabilised.

Disclosed is a method for the preparation of a cell therapeutic agent for autoimmune immune diseases based on the ability of B cells to control the differentiation of T cells, which are responsible for self tissue destruction. The method comprises (A) separating B cells from blood or bone marrow of an individual suffering from an autoimmune disease selected from among multiple sclerosis, type 1 diabetes mellitus, rheumatoid arthritis, and Hashimoto's thyroiditis; (B) primarily culturing the B cells in a culture medium supplemented with a B cell proliferation-inducing factor in the presence of an antigen causing the autoimmune disease! and (C) secondarily culturing the B cells in a fresh culture medium supplemented with a B cell proliferation-inducing factor in the presence of an antigen causing the autoimmune disease. A cell therapeutic agent therefor can be prepared. The cell therapeutic agent shows highly persistent therapeutic efficacy against autoimmune diseases, such as multiple sclerosis, type 1 diabetes mellitus, rheumatoid arthritis, and Hashimoto' s thyroiditis without side effects.
