Abstract: A machining surface of a die are provided with a pair of inclined surfaces facing each other across a gap and a flat surface interposed therebetween. Each inclined surface includes an inner end portion on a side near the flat surface and an outer end portion on a side farther away from the flat surface. The molding method includes a mounting step of mounting the metal sheet on the die to span both inclined surfaces, and a pressing step of forming a reduced-thickness portion by pressing the metal sheet between the punch and the inclined surfaces of the die. The pressing step includes setting a bottom dead center of the punch to maintain a gap formed between the inner end portion and a surface of the metal sheet facing the inner end portion.

Abstract: A piston ring which is resinous includes an annular main body portion having an inner peripheral surface and an outer peripheral surface facing each other and a pair of side surfaces interconnecting the inner peripheral surface and the outer peripheral surface and a joint portion 3 formed in the main body portion. The joint portion has a step shape when viewed from at least one of the pair of side surfaces and the outer peripheral surface. The outer peripheral surface has a tapered surface having an outer diameter increasing from a side of one side surface of the pair of side surfaces of the main body portion toward a side of the other side surface.

Abstract: The present invention relates to the discovery that a secretory phospholipase A2 (sPLA2-IIA) plays an active role in mediating cellular signaling leading to an inflammatory response or cell proliferation by way of its specific binding with integrin ? at site 2 of integrin ?. More specifically, the invention provides a method for identifying inhibitors of inflammatory or proliferative signaling by screening for compounds that interrupt the specific binding of sPLA2 and integrin ? at site 2. The invention also provides the novel use of a substance that suppresses the specific binding between sPLA2 and site 2 of integrin? for the purpose of treating or preventing a condition involving an undesired inflammatory response or cell proliferation.
