  • Patent number: 5664453
    Abstract: A hollow extruding die for extruding a hollow section of a zinc-containing aluminum alloy is provided. The die is protected from cracks and has an extended life, without requiring any substantial structural changes to the die. In the die mandrel of the die a mandrel is connected by bridges with an outer cylindrical member. The bridges have a tapered projection facing toward the mandrel. A 3 mm thick coating composed of a nickel alloy is bonded on the surface of the projection by padding the welding material. Instead of coating the bridges, a covering can be attached to the surface of the bridges. To receive the covering, an engaging groove extends from the root of the mandrel and along the surface of the bridges to the outer cylindrical member of the die mandrel. The covering is composed of the same steel material as that of the die or of the nickel alloy. The covering has a through hole for receiving the mandrel formed on the base.

  • Patent number: 5515150
    Abstract: A copying apparatus provided with an automatic document feeder having two sheet-discharging modes. One is a first-discharging mode in which a cut-sheet document subjected to exposure processing in an image reading section is conveyed to a sheet discharge section disposed on the downstream side, and the document is inverted in the sheet discharging section and then discharged to the outside of the apparatus. The other is a second sheet-discharging mode in which a continuous document is discharged from the sheet discharge section to the outside of the apparatus.
