Abstract: A punching die for punching out a seal member from a sheet of an inorganic fiber mat having a contour. The punching die includes a base plate. A first blade is supported on the base plate and has a cutting edge extending to form a loop. The first blade punches out a frame-shaped unnecessary portion, which includes the contour, and a seal member formation portion, which includes the seal member, from the inorganic fiber mat. A second blade, which is supported on the base plate at an outer side of the first blade, partially cuts the frame-shaped unnecessary portion. The at least one second blade forms a perforation in the frame-shaped unnecessary portion to separate the unnecessary portion into a plurality of unnecessary fragments. This improves productivity for production of the seal members.

Abstract: A punching die for punching a sheet of an inorganic fiber mat to manufacture a holding seal member for winding around an exhaust gas purifier body. The punching die includes a base plate. A punching blade, supported by the base plate, punches the inorganic fiber mat to cut out the holding seal member. A plurality of elastically deformable elastic members are adhered to the base plate.

The punching die includes a base plate and a first blade supported on the base plate. The first blade punches out a frame-shaped unnecessary portion, which includes the contour of the inorganic fiber mat, and a seal member formation portion, which includes the seal member, from the inorganic fiber mat. At least one second blade is supported on the base plate at an outer side of the first blade. The second blade punches and cuts the frame-shaped unnecessary portion into a plurality of unnecessary fragments. Accordingly, the punch die improves productivity for the seal member.

Abstract: A punching die for punching a sheet of inorganic fiber mat to manufacture a holding seal member for winding around an exhaust gas purifier body. The punching die includes a base plate. A double-edged punching blade, supported by the base plate, punches the inorganic fiber mat to cut out the holding seal member.

Abstract: A translucent decorative board for use, e.g., as a window pane, light shade, partition or door pane is disclosed. The decorative board is comprised of a translucent substrate board and translucent cover sheets bonded to the surfaces of the substrate board. The substrate board is generally thermoplastic and the decorative cover sheets are thermosetting. The thermosetting sheet may comprise a substrate paper sheet and a thermosetting resin impregnated in the sheet.

Abstract: A lip type seal (3A) has an annular casing (31), a plurality of seal lips (32, 34) and a rear surface support ring (35) arranged at the rear side. The casing (31) is installed to an inner circumferential surface of a seal installation part (1a) of a shaft hole housing (1) of an equipment through a main gasket (36) made of rubber state elastic material. An inner circumferential part of the seal lips (32, 34) is closely contacted with an outer circumferential surface of a rotary shaft (2). A sub-gasket (41) made of a material having a CO2 transmission coefficient being smaller than that of rubber material is interposed between the rear surface support ring (35) and the shaft hole housing (1).
