摘要： PURPOSE:To obtain a catalytically active state by a reduced quantity of power in a metal carrier catalyst for purifying exhaust gas, by providing a device supplying a current to a metal carrier and providing a part where the resistance of the current supply route of the metal carrier becomes locally large on the inflow side of exhaust gas. CONSTITUTION:In a metal carrier catalyst for purifying exhaust gas consisting of a metal carrier composed of an outer cylinder 3 in which a honeycomb body 1 constituted of metal foil is inserted, the catalyst support layer formed to the surface of said carrier and the catalyst metal supported on the catalyst support layer, a device consisting of a power supply 4 supplying a current to the metal carrier and a lead is provided and a part where the resistance of the current supply route of the metal carrier becomes locally large is provided on the inflow side of exhaust gas. Since heat generation is concentrated and large heat value is obtained by increasing local resistance, a part reaching active temp. at an early state is generated. The exhaust gas passes through said and the heat exchange with the exhaust gas is generated to heat the whole of the catalyst.

摘要： PURPOSE:To obtain a member thermally sprayed with ceramics, by preheating the surface of an Al alloy member to a specified temp. and forming a thermally sprayed layer of ceramics on the member with a bonding layer in-between so as to increase the adhesive strength of the bonding layer and to prevent the stripping and falling of the thermally sprayed layer. CONSTITUTION:The surface of an Al alloy base material is preheated to a high temp. of 260-500 deg.C and a bonding layer is formed by thermal spraying. Since the bonding layer is formed after the preheating, a diffusion layer is allowed to exist on the interface between the bonding layer and the base material so that it accounts for 20-30% of the whole interface, and the interface between the diffusion layer and the base material is made finely uneven to about several mum range. A thermally sprayed layer of ceramics is then formed on the bonding layer. By this method, the adhesive strength of the bonding layer to the base material is increased, satisfactory adhesive strength is provided to the thermally sprayed layer as a whole and cracking due to thermal stress or the like can be prevented.

摘要： PURPOSE:To improve an observation state by an electron microscope, by a method wherein a specimen solution having fine particles suspended therein is dispersed by the use of vibration energy excited at the leading end of an ultrasonic vibrator to form an aerosol which is, in turn, collected on a specimen support film. CONSTITUTION:A specimen solution having fine particles preliminarily dispersed therein is held in the recessed part 23 formed to the leading end of a vibrator main body 22. Next, the switch 64 of a power source 62 is turned ON to supply a current to a piezoelectric element 24 and ultrasonic vibration is generated in the piezoelectric element 24. By this mechanism, the vibration is transmitted to the vibrator main body 22 and energy density becomes max. at the recessed part 23 provided to the leading end of the main body 22 and, therefore, the specimen solution is formed into an aerosol 8 to be scattered from the recessed part 23. The scattered aerosol 8 is allowed to naturally fall on the specimen support film 9 placed on the flat surface 41 of a holding stand 4 under gravity to be sampled as a microscopic examination specimen.

摘要： PROBLEM TO BE SOLVED: To provide a reforming apparatus in which a water gas shift part is miniaturized as the catalytic performance enough to control the concentration of CO in a reformed gas to a prescribed value is maintained with a simple structure and which is suitable for an on-vehicle equipment and has excellent practicability.

The reaction quantity of CO is increased by increasing the temperature of the reformed gas to be introduced into the pre-stage shift catalyst C1 and the concentration of CO is further reduced by cooling the gas to be introduced into the post-stage shift catalyst C2 with air or water passing through the heat exchanger 5 to change the equilibrium and as a result, the apparatus is miniaturized.

摘要： PROBLEM TO BE SOLVED: To enable the rapid rise of temperature at the time of start of an engine by reducing the heat capacity of the heating part of an electric heating type catalyst device. SOLUTION: A metal flat foil 10 having an insulating layer comprising a first metal oxide on its surface and a corrugated foil 20 are laminated and electrodes are connected to both ends of the foil laminate to constitute the electric heating type catalyst device. The metal flat foil and the corrugated foil are bonded by brazing using a brazing material formed by holding both sides in the lateral direction of a brazing material with a predetermined width containing a third metal having reducibility larger than that of a second metal by a braizing material containing the second metal having reducibility larger than that of a first metal. Since the flat foil and the corrugated foil are bonded only by the continuity part in the lateral direction of the braizing material containing the third metal, the cross-sectional area only of the continuity bonded part can be set extremely small while the whole bonding area of the bonded part is taken largely to ensure the bonding strength of the laminate and the rapid rising of temperature is enabled by the reduction of heat capacity and an increase in current density.

摘要： PROBLEM TO BE SOLVED: To lower soot ignition temp. and to enable the combustion of particulates PM at the temp. of exhaust gas by using an exhaust gas purifying catalyst composed of a specific spinnel type composite oxide. SOLUTION: As this catalyst, a spinnel type composite oxide represented by general formula, AB2 O4 (wherein A is a transition metal capable of taking a bivalency in an oxidized state and at least one of Fe, Co, Ni, Cu, Zn, Cd, Pt and Hg and B is Ce) is used. By using this spinnel type composite oxide as a catalyst, soot ignition temp. can be lowered. This mechanism is considered to be generated because the difference between the electron state of a spinnel structure and an electron state peculiar to an element, especially, an electron state at a time when Ce is sued as B exerts effect on soot ignition temp.
