摘要： PROBLEM TO BE SOLVED: To make simple the check of the position between a powder supply nozzle and a valve seat in the longitudinal, lateral and vertical directions. SOLUTION: A powder supply nozzle 16 is furnished with the first passage 31 penetrating in the powder supplying direction and the second passage 32 branching from the first passage 31 and leading to a powder supply source. A measuring bar 34 as a jig is inserted through the first passage 31 and is equipped with graduations 34a to serve as creterion for judging the position over the height. In the condition that the measuring bar 34 is inserted through the first passage 31 is in contact with a valve seat 33, position checking between the nozzle 16 and valve seat 33 in the direction over the height is conducted from the positional relationship between the graduations 34a and the nozzle foremost face 16a. Also from the contacting position of the bar 34 with the valve seat 33, position checking between the nozzle 16 and valve seat 33 is made in the directions fore and aft and to the left and right.

摘要： PROBLEM TO BE SOLVED: To improve reliability of a fine particle circulating valve, so as to high-accurately perform circulating control of a fine particle. SOLUTION: This valve has a circulating path 18 formed in a main body 17 and a valve plug 19 traversing the circulating path 18. Between the circulating path 18 and a bearing 20 serving as a support means of the valve plug 19, an accumulating part 23 of a fine particle P, infiltrating from the circulating path 18 to a slide part of the main body 17 and the valve plug 19, is provided. By collecting the fine particle P in the accumulating part 23, the bearing 20 is prevented from being damaged by infiltration of the fine particle P. A fine particle discharge path 24 is provided in the accumulating part 23, a fine particle P accumulated therein also can be discharged to outside a valve.

摘要： PROBLEM TO BE SOLVED: To enable continuous driving while controlling very accurately the feeding amount of powder feeding equipment. SOLUTION: This powder feeding device 7 is provided with a subhopper 12 which keeps a powder temporarily, a quantitative feeding device 4 which measures the powder and a powder feeding nozzle 16 from which the powder is supplied. When the amount of the powder in the subhopper 12 becomes less than a set amount, a main hopper 8 supplements the powder. Because the control means of this powder feeding equipment understands the supplied amount of the powder from a mass decreased per unit length of time of the powder in the subhopper 12, and thus understands accurately the powder stored in the subhopper 12 and the amount of powder being supplied presently, the powder is not supplemented while the same is being supplied. From the same reason, while the powder is being supplemented, the powder is not supplied.

摘要： PURPOSE:To increase the efficiency of absorption of laser beam energy in powder and to enable treatment such as building up or alloying with low energy by dispersing and sticking fine particles to the surfaces of particles of a relatively large particle size and using the resulting combined powder. CONSTITUTION:Fine particles of 0.1-10mum particle size are dispersed and stuck to the surfaces of body particles of 20-200mum particle size having the same compsn. as the fine particles to obtain combined particles. Mechanical alloying or sticking at the time of atomization may be adopted as the dispersing and sticking method. The stuck particles on the surfaces of the body particles cause multipath reflection at the time of laser beam treatment and enhance the efficiency of absorption of laser beam energy. The combined particles hardly cause scattering because of the relatively large particle size and has satisfactory flowability.
