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

A sintered alloy having improved wear resistance at high temperatures, comprising a soft, predominantly iron matrix having a Vickers hardness of 100-200 containing more than 5 but at most 20% Mo, together with 0.5-1.5% carbon and at least one additive selected from the group consisting of nickel, cobalt and chromium, with said additive constituting at most 25% by weight of said alloy, and most of said molybdenum being contained in Mo-Fe particles having a Vickers hardness of 600-1300 which are uniformly distributed within said matrix and have an average diameter of 20-70 microns.

Sintered alloy having wear-resistance at high temperature

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.

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

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.
