摘要： PURPOSE: To dephosphorize coke forreductive refining of metal oxide, etc. by a simple process inexpensively, by carrying out dephosphorization wherein coke is treated with a specific acid.
CONSTITUTION: Porous coke containing phosphorus caused by external matters, existing in a spot way microscoplically, is immersed in an acid (e.g., HCl, H
2 SO
4 , HNO
3 , etc.) at ≤5pH at room temperature for 2hr, so that phosphorus is extracted and removed. Rise in temperature of the solution can extremely increase dephosphorization speed.

摘要： PURPOSE:To easily improve the impact resistance of the subject joint form by incorporating a specified amount of ceramic fine powder in a brazing filler metal at the interface between a ceramic and metal constituting the joint form. CONSTITUTION:Firstly, active metal (e.g. Ag-Cu-Ti)-contg. metallic powder is incorporated with ceramic (e.g. alumina) fine powder so that the ceramic fine powder account for 5-20vol.% of the brazing filler metal at the interface of the final joint form, followed by kneading together with an organic binder into a pasty product (A). The component A is then applied on the surface of a ceramic (e.g. silicon nitride ceramic) (B) followed by heating under a vacuum to produce a metallized product (C). Thence, the component C and a metal (D) is mutually brazed with a Ag-Cu-based brazing filler metal powder through e.g. vacuum brazing technique, thus obtaining the objective joint form made up of the silicon nitride ceramic 1, the brazing filler metal 2, the alumina fine powder 3 and the metal 4.

摘要： PURPOSE:To enhance line efficacy of a deodorizer of a small air conditioner which has a restraint of the available space and the capacity of the fan, by attaching a deodorant on the inner wall located on the upstream side of the airflow of an evaporator of the air-conditioner and adjacent to the evaporator. CONSTITUTION:The drawing shows the cross-section of an indoor unit of a small air-conditioner. Air enters the indoor unit through a suction grille 1, passes through a pre-filter 4 and a fan 2 to an evaporator 3 where heat exchange takes place, and is discharged from an air outlet 5. A deodorant 6 is a metallic porous substance composed of iron-ascorbic acid and attached on the inner wall adjacent to the evaporator 3. Iron is treated with ascorbic acid, citric acid, etc., to produce the deodorant 6 in which metal and reaction products coexist. The deodorant 6 is capable of absorbing and decomposing odor components and its efficacy lasts for a long time period. As the air retained inside is deodorized during stoppage of the air-conditioner, the deodorizer is excellent in economy and efficacy with simple method and can be additionally attached to the air-conditioner without changes in design such as an increase in the capacity of the fan 2 to compensate the pressure drop.

摘要： PURPOSE:To enhance bonding strength by restraining one end of a metallic base plate and holding the other end thereof with a spring body and arranging the ceramics pieces via brazing material and fitting a presser plate thereon via the spring body and thereafter heating the whole body to braze it. CONSTITUTION:A base plate 2 made of metal is fixed to a fixed frame 5 made of stainless steel so that the base plate 2 can be extended and contracted to the directions of the sides 2c, 2d by a heat resistant spring body 6. Brazing material 21 is interposed on this base plate 2 and the ceramics pieces 1 such as metallized Si3N4 are arranged. A heat resistant spring body 3 is placed on the ceramics pieces 1 and a presser plate 4 is fitted thereon. This presser plate 4 can be extended and contracted to the directions of the sides 4c, 4d by a heat resistant spring body 7 and furthermore is fitted to the fixed frame 5 so that it can be raised by a heat resistant spring body 3. Then the whole body is introduced into a furnace in this state and heated at about 840 deg.C for about 30 minutes in the argon atmosphere to perform brazing and joining and thereby a composite body of ceramics and metal is obtained.

摘要： PURPOSE:To join a ceramic to a metal without producing cracking, etc., by interposing a gap member having a cushioning function between the sides of adjacent ceramic pieces when many pieces are brazed onto a metallic base. CONSTITUTION:Many ceramic pieces 1 are placed on a metallic base 4 (e.g., an iron base) with a solder 2 in between. The gap member 5 (e.g., a copper sheet) having a cushioning function is interposed between the sides of adjacent ceramic pieces 1, and the base 4 is thermally joined to the ceramic piece 1. As a result, the joined ceramic piece 1 on the base 4 is not compressed by the adjacent piece 1, hence cracking is not produced with the contact point between the ceramics 1 as a starting point, the ceramic 1 is not broken and released, and a sound joined body can be produced.

摘要： PURPOSE:To firmly bond a porous ceramic to a metal without producing cracking, etc., by interposing a ceramic having about the same thermal expansion coefficient as the porous ceramic and higher strength between the bonding surfaces. CONSTITUTION:A ceramic 20 (e.g., high-strength alumina ceramics) having a thermal expansion coefficient equivalent or similar to that of a porous ceramic 1 (e.g., porous alumina ceramics) and higher strength than the ceramic 1 is interposed between the ceramic 1 and a metal 3 (e.g., copper sheet). In this case, the porous ceramic 1 is firstly bonded to the ceramic 20, and then the ceramic 20 is bonded to the metal 3. As a result, thermal stress is not developed between the porous ceramic 1 and the ceramic 20 during the bonding, and the thermal stress developed between the ceramic 20 and the metal 3 is absorbed by the high-strength ceramic 20.

摘要： PURPOSE:To obtain a metallized ceramic excellent in bond strength at temperature and hot strength characteristics by bringing Ni metal into contact with a metallizing layer formed on a ceramic surface with Ag-Cu-Ti-based metal followed by heating treatment under specified conditions. CONSTITUTION:Firstly, metallization treatment is applied on a ceramic surface using Ag-Cu-Ti-based metal to form a metallizing layer on the surface. Thence, Ni metal is brought into contact with this layer followed by heating treatment in a vacuum or inert gas atmosphere at 650-900 deg.C to effect diffusion of Ni into the layer. Alternatively, after forming a metallizing layer on the surface as described above, glaze is attached on both surfaces of the metallizing layer and a metal to be put to contact with said layer, and furthermore, a Ni-plated layer-clad thermal stress-buffer material is put between both the surfaces. Thence, the system is heated in a vacuum or inert gas atmosphere at 650-900 deg.C for >=10min, thus bonding the ceramic to the metal.
