    摘要： Magnet powder has a composition expressed by (R1XR2YBZT100−X−Y−Z)100−QNQ (in formula, R1 is at least one kind of element selected from rare earth elements, R2 is at least one kind of element selected from Zr, Hf and Sc, T is at least one kind of element selected from Fe and Co, and X, Y, Z and Q are numbers satisfying 2 atomic %≦X, 0.01 atomic %≦Y, 4≦X+Y≧20 atomic %, 0≦Z≦10 atomic %, and 0.1≦Q≦20 atomic %, respectively), and TbCu7 crystal phase as a principal phase. In such magnet powder, a ratio of fine particles of which maximum diameter is 22 &mgr;m or less is 20% by weight or less. Alternatively, surface roughness of particles constituting the magnet powder is 5 &mgr;m or less in terms of maximum height Ry provided in JIS B 0601-1994. Accordingly, to such a magnet powder, excellent magnetic properties can be obtained with reproducibility.

    摘要： There is provided a four-cycle engine which can appropriately circulate oil in an engine regardless of a tilted condition with a simple structure. A crankcase (4) of a four-cycle engine (1) has a crank room (41) which rotatably supports a crankshaft (10) and an oil room (42) which is provided adjacent to the exterior of the crank room (41). The crankcase (4) also has partition walls (43) and (44) which partition the interior of the crankcase (4) into the crank room (41) and the oil room (42), respectively, and a communication path (45) which communicates the crank room (41) with the oil room (42). The partition walls (43) and (44) each has a cross section formed in a substantially V shape, and the communication path (45) is formed at an apex between the partition walls (43) and (44).
