摘要:
Anisotropic permanent magnets of Mn-Al-C polycrystalline alloy are produced by warm extrusion at a temperature of 530.degree. to 830.degree. C utilizing converging or tapered dies with lubricant interposed between the polycrystalline body and the converging die. With dies of rather small semiangles, alloys with improved magnetic properties with regard to (BH)max, and especially Br are obtained.

The absorbent article of the present invention comprises: a liquid-pervious surface sheet, a liquid-impervious backside sheet provided at the position opposing said surface sheet, and an absorption body provided between said surface sheet and said backside sheet, wherein the absorbent article comprises an endless compressed groove, surrounding a central part of said absorbent article, which is formed in said surface sheet and said absorption body in the thickness direction, and a plurality of concave parts, provided inside and outside said compressed groove, which are formed in said surface sheet and said absorption body in the thickness direction, and an uncompressed region bordering inner and outer edges of the compressed groove, wherein the closest distance between said compressed groove and the nearest concave parts is greater than the distance between adjacent ones of those same concave parts.
摘要:
A plurality of convex portions that protrude radially outward from a plurality of positions separated in the circumferential direction are provided on the outer peripheral surface of a driven gear. Each convex portion has, in the circumferential direction of the driven gear, a rising surface that rises from a minimum diameter position to a maximum diameter position in the direction opposite the rotational direction of the driven gear, and a falling surface that falls from that maximum diameter position to a minimum diameter position that is adjacent to and in back of that maximum diameter position with respect to the rotational direction of the driven gear. The circumferential length of the falling surface is greater than the circumferential length of the rising surface.
摘要:
An absorbent article package is individually packaged by folding a packaging sheet and an absorbent article in a state where the absorbent article is arranged on the packaging sheet. In a state where the individually-packaged absorbent article is opened, in the packaging sheet and the absorbent article, a first folding line based on which the absorbent article and the packaging sheet are folded towards the topsheet side, and a second folding line based on which the absorbent article and the packaging sheet are folded towards the backsheet side are formed adjacent to each other in the longitudinal direction.
摘要:
According to the present invention, an HCV replicon-replicating cell is produced by a production method including a step of introducing RNA containing an HCV replicon sequence and a selectable marker gene sequence into a Li23 cell or a cured cell derived from a Li23 cell. Further, a full-length HCV RNA-replicating cell is produced by a production method including a step of introducing RNA containing a full-length HCV genome sequence and a selectable marker gene sequence into a Li23 cell or a cured cell derived from a Li23 cell. The use of these cells enables the construction of an HCV life cycle reproduction system that is derived from a cell line other than the HuH-7 cell line and that has capabilities equivalent to those of an HCV life cycle reproduction system derived from the HuH-7 cell line.
