Abstract: A method for producing a thermal spray powder includes: a preparing step of preparing a powder mixture containing a first particle made from zirconia-based ceramic containing a first additive agent and a second particle made from zirconia-based ceramic containing a second additive agent, the powder mixture having a 10% cumulative particle diameter of more than 0 ?m and not more than 10 ?m; and a secondary-particle producing step of producing a plurality of secondary particles each of which includes the first particle and the second particle sintered with each other.

Abstract: A partition pole system for guiding visitors in public spaces, buildings, or the like has a plurality of spaced partition poles each composed of a base and a hollow pole mounted on the base, and a plurality of partition cords housed in the poles, respectively, for withdrawal therefrom through respective withdrawal holes thereof. A connector is mounted on a distal end of each of the partition cords for connection to the coupling of another pole. Each of the poles houses a vertically movable weight for pulling each of the partition poles into one of the poles, and a releasable stopper for keeping each of the partition cords withdrawn out of one of the poles. The poles may be vertically mounted on the respective bases or inclined with respect to the respective bases.
