  • Patent number: 7287297
    Abstract: A cleaning apparatus includes a pressure pad for a cleaning fabric. The pressure pad comprises a particular portion formed on a base portion. The base portion has a predetermined hardness. The particular portion has a predetermined hardness which is lower than the hardness of the base portion. The cleaning fabric is nipped between the particular portion and a subject to clean the subject with the cleaning fabric.
    Type: Grant

  • Patent number: 4101317
    Abstract: The present invention provides copper base alloys containing copper and zinc as the main components with additions of tin, lead, nickel, iron and beryllium and one of the objects of the present invention is to increase not only the corrosion resistance, but also, the machinability by defining the range of the composition as 63.0-66.0 wt.% copper, 1.2-2.0 wt.% tin, 1.0-2.0 wt.% lead, 0.1-1.0 wt.% iron, 2.0 wt.% or less of nickel, 0.1 wt.% or less of beryllium and the rest being zinc with inevitable impurities. In another aspect of the invention, the above composition is subjected to a heat treatment between about 350.degree. and 550.degree. C for about 1 to 10 hours after hot and cold working which produces a further significant improvement in machinability without decreasing either the corrosion resistance or the mechanical properties.
