A catalytic converter having a catalyst carrier for purifying exhaust gas of internal combustion engines for motor vehicles such as automobiles, motorcycles and motorbikes. The carrier comprises a plurality of catalyst carrier pieces which are molded into a predetermined block by binding or sintering at high temperature so that the block is resistant to vibration damage.

Catalytic converter having vibration-resistant catalyst carrier

The present invention relates to an anti-vibration heat-insulation structure and a process for the production thereof characterized by filling the void in the structure to form a heat-insulation layer with silicic acid bonding agent-coated silicic acid mineral grains which swell in volume when fired at a high temperature; and then heating and thereby expanding these silicic acid mineral grains and at the same time allowing said grains to stick to one another.

Anti-vibration heat-insulation structure and a process for production

Foamed sodium silicate ceramic obtained by mixing sodium silicate 30-36% by weight of aluminum hydroxide or 30-36% by weight of aluminum hydroxide and 5-20% by weight of ceramic fibers; and method of manufacturing the same.

Foamed sodium silicate ceramic and method of manufacturing the same

Method of manufacturing composite heat-insulating material, by stacking to a desired thickness pieces of aluminum foil adhesively secured to foam-forming ceramic material, filling the volume to be occupied by said heat-insulating layer or a vessel with the resulting stack, and heating it to cause foaming of said ceramic material.

Method of manufacturing composite heat-insulating material

The present invention relates to heat insulating castings of triple structure consisting of heat and corrosion resistant metal, heat insulating refractory material, and cast metal. The invention is characterized in that heat and corrosion resistant metal sheet is covered with heat insulating refractory material and the thus formed assembly is enveloped with cast metal. Fringe areas are provided at the ends of the heat and corrosion resistant metal and these fringes are enveloped with cast metal.

Heat insulating castings

The present invention relates to a method of manufacturing a metal-impregnated body in which a porous body is immersed under sub-atmospheric pressure in a molten alloy for impregnation with said alloy or a porous body is immersed under elevated pressures produced by various gases, the pressure then being reduced to normal level, after which the porous body is introduced together with a molten alloy into a metal mold, in which said molten alloy is impregnated into said porous body. The porous body is then separated from said molten alloy.

Method of manufacturing a metal-impregnated body

In a fabricating process of a metallic honeycomb structure, a plurality of bar soldering materials are laid on a plurality of metallic structure members previously assembled as a honeycomb structure and melted in a heating kiln to complete the soldering joint.

Manufacturing method of metallic honeycomb structures

A method for producing a heat-insulating casting characterized by placing a flexible ceramic semifinished product having a smooth surface, a modulus of elasticity of 200-5000 Kg/mm.sup.2, a bending strength of 8-200 Kg/cm.sup.2, and a wall-thickness less than 1/4 of the inside diameter, inside a casting mold, and casting molten metal so as to enclose the ceramic semifinished product.

Method for producing heat-insulating casting

An aluminum alloy piston for an internal combustion engine, which has been made wear and seizure resistant by forming an adherent coating on at least the skirt of said piston, by applying thereto an iron-carbon powder containing less than 0.3% by weight of C, the balance being substantially all iron. A film of manganese phosphate may be subsequently applied to said skirt.
