The disc brake for a motor vehicle contains a caliper bracket to be secured to a vehicle body on the outer side of a disc rotor with respect to the vehicle body, a caliper body supported by the caliper bracket to be slidable in the axial direction of the disc rotor and a pair of friction pads disposed to oppose each other through the disc rotor. The caliper bracket contains a bracket main body and a connecting arm which are disposed respectively on the outer side and on the inner side of the disc rotor with respect to the vehicle body, as well as, a pair of caliper supporting arms, which connect the bracket main body with the connecting arm at their disc turning-in side end portions and at their disc turning-out side end portions, respectively. The bracket main body and the connecting arm have torque receiving portions at least on the disc turning-out side respectively to receive braking torques from the respective friction pads; the bracket main body has a disc turning-out side fixing portion, where the caliper bracket is secured to the vehicle body, located outer than the disc turning-out side torque receiving portion toward the disc turning-out side and substantially on the peripheral edge of the disc rotor.

A gas reactor includes a dielectric casing made of a dielectric material and forming a first conduit for directing first gas in one direction, a first electrode positioned inside the dielectric casing along a general center thereof and extending in the direction, at least one catalyst layer formed on a surface of the first electrode, and a second electrode surrounding an outer wall of the dielectric casing. The gas reactor further includes a power-supply unit applying AC power between the first electrode and the second electrode to generate glow discharge inside the dielectric casing.

Gas reactor for plasma discharge and catalytic action

Gas reactor using a plasma for cracking or synthesizing gases

Gas-cleaning equipment is disclosed, which comprises a housing having an intake vent and an exhaust vent and having disposed between the two vents a fan having at least one rotating blade. Air pollutant-removing system using the gas-cleaning equipment is also disclosed. This gas-cleaning equipment can effectively clean a gas through the action of plasma produced by glow discharge caused by rotation of said fan. When a metal layer having a catalytic activity is fixed onto the surface of said rotating blade, this metal layer also functions to effectively clean the gas. In the case where both the plasma and the metal layer function to clean the gas, there car be obtained synergistic effects. Cleaning of the gas can be conducted with more efficiency by bringing the intake gas into contact with the fan in an oxygen-free state. A magnet provided as an outer wall of the housing serves to generate plasma with higher density, leading to more effective cleaning of the gas. As the metal layer showing catalytic activity, at least one noble metal selected from the group consisting of platinum, palladium, ruthenium and rhodium. This gas-cleaning equipment shows markedly excellent gas-cleaning ability considering its compact size, and can remove air pollutants particularly when applied to the exhaust system of automobiles or to outdoor structures such as buildings or props.

A gas purifier comprising a casing, and two magnetically sensitive reeds arranged in the casing so that one reed extends from one end wall of the casing and the other reed extends from the other end wall of the casing and the free ends of the reeds overlap one above another with a small gap therebetween to form opposing contacts. The magnetically sensitive reeds are magnetically moved by a driving coil so that the contacts are opened and closed like a switch. This operation of the contacts and the contact load coil induces a glow discharge by which a gas is purified by an action of the plasma. A catalyst is carried by the contacts or the casing. Therefore, gas is purified synergically by the action of the plasma and the action of the catalyst. It is also possible to operate the magnetically sensitive reeds, or the like electrodes, by an AC voltage to induce a glow discharge.

Gas purifier using plasma and catalyst

A switch is disclosed comprising two sets of rod-shaped fixed electrodes formed of a magnetic material and one cylindrical moving electrode formed of a permanent magnet, each set of the fixed electrodes being fixed to the respective end of a cylindrical vessel so that the ends of each set of the fixed electrodes face the ends of the other set of the fixed electrodes with the moving electrode capable of reciprocating between the ends of the two sets of fixed electrodes inside the cylindrical vessel. The moving electrode is comprised of at least one adhesive layer of a metal selected from the group consisting of silver, nickel, copper and alloys thereof on the surface of the permanent magnet, and at least one contact layer of a metal selected from the group consisting of rhodium, wolfram, rhenium, ruthenium and alloys thereof, silver-wolfram, gold-chromium on the adhesive layer of metal. At least the permanent magnet of the moving electrode and the adhesive layer of metal are thermally diffused with each other.

Switch

Electrical contacts are produced by processes comprising (1) forming on a metallic body a first layer of low melting metal(s) and (2) forming on the first layer a second layer of high melting metal(s). The thus produced contacts possess prolonged life, approximately 10 times that of conventional contacts when they are operated as working contact.
