摘要： Improved disc metal mold provides an improved disc without a ring groove thereon. The improved disc metal mold has a fixed metal mold section and a movable metal mold section for forming a cavity therebetween. One of the fixed and movable metal molds has a stamper having an information signal surface on which an information signal is formed in a form of pits, wherein a fused resin is injected into the cavity to form a disc substrate having a center through hole at the center thereof. The disc metal mold includes the stamper having an center hole at a center thereof for retaining the stamper itself and a retainer for retaining the stamper to engage with the center hole of the stamper. The retainer has a slightly larger diameter at a top surface thereof than a diameter of the center hole of the stamper so that the top surface of the retainer is approximately flush with the information signal surface of the stamper by causing the top end thereof to engage with the center hole of the stamper. Thus, it is possible to provide a recorded disc having a seamless flush information surface without ring groove.

摘要： The present invention relates to a method of joining a hub 11 and a shroud 12 of an impeller 10, either one of which has blades 13 integrally formed thereon, by welding. During the welding, in an upright state in which the hub 11 is placed to face a mount surface, the hub 11 and the shroud 12 are placed on top of each other to form an assembled body 10. Welding is performed on the assembled body 10 covered with a heat insulating jacket 30(a to g), the jacket 30 covering the assembled body 10 except an open region (OP) and an inflow port 14IN required for welding. When welding of one open region OP is completed, a new open region OP is formed by moving the heat insulating jacket 30 with respect to the assembled body, and then the next welding is performed.
