摘要： PURPOSE:To effectively restrain vibration while melting a billet and to stably manufacture powder at high rate by supporting a rotating shaft for rotating the billet with a magnetic bearing. CONSTITUTION:A plasma torch (electrode) 6 and the billet 7 cylindrically formed of raw material, are set with the same axis just below an electrode inserting hole 5. The billet 7 is directly connected with rotating shaft 23 in a magnetic spindle 22 arranged at lower part of a chamber 1 and freely rotated around the axis. The magnetic spindle 22 rotates the rotating shaft 23 at high velocity while holding the rotating shaft 23 to the condition without contact with an electromagnet interposed between the rotating shaft 23 and a main body 24. When plasma arc generates between the plasma torch 6 and the end face of the billet 7, the end face of the billet 7 is melted, and the molten metal is spattered with centrifugal force to manufacture the powder. Even in the case imbalance is developed in the billet, the powder can be stably manufactured.

摘要： PURPOSE:To improve magnetic characteristics even with thin shape by making an R2P14B intermetel compound phase, which is oriented in the direction of crystallographic C axis by rolling recrystallized organization and takes tetragonal structure of specific crystal diameter, a main phase. CONSTITUTION:The R2Fe14B intermetal compound phase taking tetragonal structure of 0.05-50mum, preferably, 0.05-10mum in average crystal diameter is made a main phase, and this main phase is recrystallized rolled organization having aggregate structure oriented in the direction of crystallographic C axis. And since there is no mixture of impurity such as O2, etc., and density ratio is almost 100%, magnetic characteristics are very stable.

摘要： PURPOSE:To obtain a lightweight and high strength vibration damping material having enough vibration damping property by providing a honeycomb structure wherein a Zn-Al base alloy partition plate divides the interval made by opposedly parting Zn-Al base alloy plates into a plurality of spaces. CONSTITUTION:The vibration damping material 1 is a rectangular plate and consists of a Zn-Al base alloy partition plate arranged between Zn-Al base alloy plates 2 and 2, which are vertically and opposedly parted from each other, so as to divide the interval made between the plates 2 and 2 into a plurality of spaces. The partition plate 3 is produced by inserting a thin rectangular sheet between preheated molds so as to press it into a corrugated form in order to join it to the plates 2 and 2 by epoxy-based resin at portions 4. Thus, since the vibration damping material concerned has a honeycomb structure consisting of the partition plate 3, which divides the interval made by opposedly parting the plates 2 and 2 into a plurality of spaces and, in addition, the plates 2 and the partition plate 3 are made of Zn-Al base alloy, which is excellent in vibration absorbing property, the material concerned can be light in weight and have high strength and further have improved vibration damping property.

摘要： PURPOSE:To improve the production efficiency by inserting wire rods into through holes of a plurality of material supporters provided in the shape of a honeycomb and extruding them at a specified straining rate through desired extruding bars. CONSTITUTION:In a container element 16, the axial section shows a regular hexagon and a through hole 18 which opens on the upper and lower end faces is formed in the central part along the axial line. When a heating element 14 is heated by a high frequency heating coil, the container element 16 is heated by the radiation heat from the element 14, the conductive heat from a container holder 17 and the heat conduction between the elements 16 uniformly into a hot processing temperature. The wire rods is inserted into the through hole 18 of the container element 16 fitted in the shape of a honeycomb, held at the hot processing temperature and extruded by a die and an extruding rod fitted at both ends of the through hole 18 at a straining rate 0.01-0.1/sec. In this manner, a plurality of wire rods can be extruded simultaneously to upgrade a production efficiency.

摘要： PURPOSE:To obtain a defective signal with a good S/N by removing noise components through a BPF which varies a flaw detection signal according to a revolving speed when the flaw detection signal is transmitted from a rotary side to a fixed side through a slip ring. CONSTITUTION:When the flaw detection signal is transmitted from the rotary side to the fixed side through the slip ring, a pulse train S1 from a precedent- stage time-division multiplex receiving circuit is inputted to an F/V converter 61 and converted into a voltage. Then, an integrating circuit 62 integrates a voltage within a constant time and averages it, and the voltage-controlled BPF63 is controlled with the averaged voltage to remove noise components from the flaw detection signal SI, thereby obtaining the defect inspection signal SO with the good S/N.

摘要： PURPOSE:To improve the accuracy of detection by rotating a rotary detection part along a body to be inspected, and passing a flaw detection signal obtained by a flaw detection probe smoothly to a fixed part side by a rotary transformer. CONSTITUTION:A rotary side coil 28 is wound spirally around the base end of a spindle 20d and a signal line is wired from the flaw detection probe 20a to the coil 28 through a passage 20p. A fixed-side coil 29 is fixed to an outside cylinder 20n through a coil support base 20q and arranged at the outer periphery of the coil 28 while a constant clearance is left. Both coils 28 and 29 constitute the rotary transformer 30 which leads the signal of the probe 20a out to the fixed side. The flaw detection signal from the probe 20a is guided and transmitted to the fixed part by the transformer 30 and passed smoothly, so the flaw detection signal is securely led out, thereby improving the inspection accuracy.
