摘要： PURPOSE:To obtain the titled material having high hardness, having small adhesiveness and having small wear and deformation at a high temp. by quench solidifying the metal compounded with Ag, etc., and the metal which separates into two phases from the same at specific ratios and dispersing the desired metallic particles into a matrix. CONSTITUTION:The molten metal contg. the matrix metal A and the metal B which separates into two phases from the same and having 0.5-20wt.% metal B for the total volume is quench solidified. In this method, the titled material in which the particles of the metal B having 0.01-1mum particle size are uniformly dispersed into the metal A and the ratio of the metal B is regulated to 0.5-20% is obtd. The metal A is selected from Ag, Au and Cu and the metal B is selected from Ni, Cr, Fe, Co, Si, Rh and V. In this composite material, since the dispersion metals are dispersed into the matrix, it can be widely used for mechanical parts, conducting paste, etc.

摘要： PURPOSE:To prolong the lighting time by furnishing a metal oxide layer around a metal wire, attaching emitter substance onto the layer to form an electrode for a discharge lamp, making the metal wire from an iron-chromium-aluminum series alloy wire, and including therein an element having a reductive power. CONSTITUTION:A metal wire 2 is prepared from an iron-chromium-aluminum series alloy wire, which should contain 10-30wt.% chromium, 1-10wt.% aluminum, 0.1-1.0wt.% element(s) having a reductive power, and iron as remainder. A bonding power is thereby given to the metal wire 2 and a metal oxide layer 3. Favorable examples of element having a reductive power are those belonging to the 3A, 4A, and 5A groups which are elements that likely to oxide and easy to reduce the surrounding elements, such as Zr, Ta, Y. The metal oxide layer 3 should consist of aluminum oxide which allows easy dispersion not only at the interface of an electron emitting layer 1 including emitter substance but also inside of the interface, and the bonding power of the electron emitting layer 1 with the metal wire 2 is heightened.

摘要： PURPOSE:To lengthen the life of an electrode by forming a metallic oxide layer over a metallic wire, and thereby letting non-organic compounds for an emitter, which includes elements furnished with reduction power for emitter material, be adhered thereon. CONSTITUTION:A metallic wire composed of a Fe-Cr-Al alloy (Cr:20, Al:48(wt.%) and remaining is Fe) is formed on a filament in a double coil shape. The aforesaid filament is sintered at 1150 deg.C for 30 minutes in an air environment, so that a metallic oxide layer 3 composed of aluminum oxide is formed on the surface of the filament. Next, 3% Ta by volume the average grain size of which is 5mum, to the total amount of the non-organic compound, is added to the slurry of alkali earth carbonate composed of BaCO3:42.0, SrCO:32.0 and CaCO3:26.0(wt.%) so as to be mixed. Let the aforesaid compound be adhered on the filament, so that an electron emitting layer 1 is thereby formed thereon. The aforesaid filament is incorporated in a fluorescent lamp, and is processed so as to be activated.

摘要： PURPOSE:To provide an electrode for a discharge lamp with improved adhesion strength of an emitter, high resistance to ion impact and a long life, and with which the lamp can have high output by forming a specified aluminum oxide layer on the circumference of a metal wire and sticking an emitter material to the surface of the aluminum oxide layer. CONSTITUTION:An aluminum oxide layer 2 is formed on the circumference of a metal wire 1 and an emitter material 3 adheres to the surface of the aluminum oxide layer 2. The surface of the aluminum oxide layer 2 is made like a whisker 2a. Though there is no specific definition for the metal wire 1, iron- chromium-aluminum alloy wires containing 10-30wt.% of chromium, 1-10wt.% of aluminum, and balance iron are preferable as the metal wire.

摘要： PURPOSE:To reduce the consumption speed of an emitter and provide an electrode for a discharge lamp with a long life by making the structure of a filament which holds an emitter wherein the filament is coiled closely on a high melting point insulator. CONSTITUTION:A slurry prepared by dispersing an alkaline earth metal carbonate salt in an organic solvent is applied to a filament (e.g. tungsten filament). Then, a filament 2 holding an emitter 1 is prepared by, for example, applying electricity the filament in vacuum an inert gas atmosphere to evaporate the solvent from the carbonate slurry on the filament surface and at the same time to convert the carbonate into an oxide. Next, the filament 2 holding the emitter 1 is coiled closely on a high melting point insulator 3 (e.g. alumina) to prepare an electrode for discharge lamps. As a result, since electric discharge is caused in a wide surface area, ion impact is dispersed and depletion of the emitter 1 is suppressed and evaporation amount of the emitter 1 is lessened.

摘要： PURPOSE:To easily inspect even a complicated shape and to enable the inspection even when the surface of a body to be inspected is covered with resin by finding the interval between a high and a low part according to the deviation angles of peaks on data obtained by diffracting X rays by the body to be inspected. CONSTITUTION:Monochromatic X rays 4 are made incident slantingly on and diffracted by an installed bellows (body to be inspected) 1. The diffracted X rays 5 from the diffracting surface are at an angle 2theta to the prolongation 6 of the monochromatic X rays 4. Diffraction patterns through a counter tube 7 by varying the angle 2theta to the diffracting surface vary in intensity according to the variation in 2theta. Then there are a diffraction pattern obtained from the diffracting surface of the high part and a diffraction pattern obtained from the low part, and the peaks of the high and low parts are obtained while clearly separated. Those two peaks are obtained by the high and low parts and their interval S, is proportional to the interval between the high and low parts of the bellows 1. Consequently, the shape of the bellows can be inspected.

摘要： PURPOSE:To restrain the change of characteristics due to the repetition of operation by specifying the material of a shape memory alloy and realizing orthorhombic phase transformation in the device wherein a circuit breaker mechanism operates with the shape change of the shape memory alloy upon the supply of overcurrent to a heater coil. CONSTITUTION:When overcurrent flows to a heater coil 9, heat generated thereby causes a rise in the temperature of a shape memory alloy spring 8. When the temperature exceeds a phase transformation start temperature level, the shape memory alloy spring 8 suddenly tends to be deformed in such a way as to push up a plunger 7. The concerned spring 8 is in a restrained condition and, therefore, when a load exceeds a sum of loads generated from the constant load bias application spring 12 of a load lever 6, the latch mechanism of a circuit breaker connected to the load lever 6 is unlocked and a circuit is thereby broken. In this case, the shape memory alloy spring 8 is made of nickel-titanium- copper metal and the phase transformation mechanism thereof related to a shape change is so made as to give orthorhombic phase transformation.
