摘要:
A circuit for detecting a physical quantity which comprises a bridge circuit including four sensitive elements having a resistivity which is variable in proportion to a physical quantity to be applied thereto. A power supply is connected to two input terminals of the bridge circuit for applying a voltage thereacross, and a variable resistor comprising a resistor having a predetermined resistance and an adjustable tap is provided for nulling the bridge. The circuit is arranged such that the zero adjustment of the output voltage may be accomplished by adjusting the resistance value of the variable resistor without affecting the characteristics of the thermal zero shift of the bridge circuit to thereby accurately obtain the output voltage corresponding to the physical quantity applied.

A method for forming a chromium carbide layer on the surface of an iron, ferrous alloy or cemented carbide article in a treating molten bath, comprising heating a mixture of boric acid or a borate and a chromium halide to its fusing state and immersing the article in the treating molten bath of said mixture, thereby forming a very hard chromium carbide layer on the surface of said article. The method of this invention can be carried out without ageing the treating bath and can form a very smooth chromium carbide layer on the surface of the article.

A method for producing a semiconductor strain sensitive element of an electromechanical semiconductor transducer, comprising the steps of forming a semiconductor crystal layer integrally and insulately on a base plate, removing predetermined portions of the semiconductor crystal layer, and providing first and second narrow grooves at the predetermined portions, thereby forming at least two elongated strip parts and a plurality of wide parts on the base plate, and forming lead mounting electrodes at predetermined portions of a plurality of the wide parts.
摘要:
An exhaust gas purifying device for burning the unburnt component contained in the exhaust gas of an internal combustion engine. A swirl of air is formed in a combustion chamber, fuel is supplied into the combustion chamber and burnt, and a combustion flame swirling in the combustion chamber is blown into a reaction chamber disposed in an exhaust pipe of the internal combustion engine. A porous member made of noncombustible material is mounted to an opening of a fuel spouting pipe opened into the combustion chamber.
摘要:
A disc brake of simple construction wherein an intermediate member is interposed between the brake pad and the brake actuating piston. Anti-friction means extends between the transverse adjacent surfaces of the piston and the intermediate member so that vibrations from the brake pad are thus not transmitted to the piston and brake squeal is effectively eliminated.
摘要:
A disc brake of simple construction wherein a supporting member of elastic material is disposed between the cylinder and piston in such manner as to allow the piston to move axially along the cylinder and to vibrate synchronously with the cylinder in the radial direction of the piston, thereby to prevent coupled vibration of the piston and the brake friction pad and to eliminate brake squeal.
摘要:
A process for the surface treatment of an iron or iron alloy stock comprising heating a mixture of boric acid or borate. A V-a group element of the periodic table consisting of vanadium, niobium and tantalum, or a substance containing the same, and carbon or a carbon containing substance to its fusing state in a bath vessel, and immersing the stock in the molten bath of said mixture, thereby forming a carbide layer of said element on the stock thus treated. The present invention can be performed without adding carbon to a mixture in the case when either said stock or said vessel includes carbon.
摘要:
The invention relates to disc brakes wherein antifriction intermediate members such as rollers, or balls, are provided between the friction pad and the piston reducing the contact area to lines or dots, thereby reducing the frictional force between opposed surfaces of the pad and the piston, to prevent brake squeal.
