Abstract: A punch unit is used in a powder press molding device that includes a die plate including a cavity in which a compacted powder pellet can be formed, the powder press molding device including a ram moving in a direction approaching the die plate and in a direction away from the die plate. The punch unit includes a punch inserted into the cavity of the die plate when the ram approaches the die plate, and a supporting portion supporting the punch reciprocatably, the punch unit being movable along a plane intersecting with the moving direction of the ram in a state where the punch is removed from the cavity. The punch unit is capable of shortening a distance in which the ram moves, and a cycle time can be shortened.

Abstract: Provided is a rotary electric machine capable of improving cooling performance for a stator coil and a stator core. In the rotary electric machine, an outer-side outer diameter portion (26) of an exhaust hole (24) is formed on an inner diameter side of a position which is opposed to an axial-direction side end surface (30) of a fan blade (27) of a centrifugal fan (13) in an axial direction. Therefore, the axial-direction side end surface (30) of the fan blade (27) and the exhaust hole (24) have a positional relationship so as not to overlap each other in the axial direction. In this manner, cooling air exhausted through the exhaust hole (24) is unlikely to be forced to return to the exhaust hole (24). Therefore, exhaust efficiency is improved to efficiently cool a stator coil (22) and a stator core (21).

Abstract: Genetic recombinant yeast expressing xylose reductase (XR), (wild-type or mutant) xylitol dehydrogenase (XDH), and xylulokinase (XK) and a method for highly efficiently producing ethanol from xylose using the yeast are provided. Pichia stipitis-derived XR and (wild-type or modified-type) XDH genes and Saccharomyces cerevisiae-derived XK gene were introduced via chromosomal integration. Thus, a genetic recombinant yeast having a high xylose fermentation rate, being capable of producing ethanol from xylose in high yields, and having high xylose fermentability in the presence of glucose, as well as a method using the recombinant yeast for highly efficiently producing ethanol from xylose or a saccharified solution from lignocellulose-based biomass are provided. Furthermore, a method for improving the xylose fermentability of the genetic recombinant yeast of the present invention via acclimatization treatment is also provided herein.
