  • Patent number: 5871393
    Abstract: When a mounting member employed for fine polishing of semiconductor substrates or glass substrates etc. is constituted of a combination of a sheet of continuous porous structure and a template, operating efficiency is lowered by the need to change the template; this is a factor raising production costs, and edge portions of the polishing workpiece get damaged by contact with the template, causing production of defective articles. By making the mounting member for polishing a member in which water repellence was conferred on at least a surface skin layer of a continuous sheet of porous structure, fine polishing without a template was made possible.

  • Patent number: 5866819
    Abstract: A non-destructive method and apparatus for determining the thickness of individual layers of different materials in a multilayer structure particularly useful in analyzing the layers in a multilayer plastic fuel tank, utilizes a constant and relatively high frequency ultrasonic pulse transmitted into the multilayer structure and records the time when interference pulses are received to determine the thickness of the individual layers in the multilayer structure. The interference pulses are generated at the interface between adjacent layers of sufficiently different materials and thus, the time between interference pulses is a function of the amount of time needed for the ultrasonic pulse to pass through a layer of material.

  • Patent number: 5862762
    Abstract: Combustible is comminuted and dried, and metal and noncombustible are removed from the coarsely comminuted combustible. Then, the combustible is secondarily comminuted and separated into coarse combustible and fluff which is fine combustible. The coarse combustible of the separated combustible is fed onto a fire grate (2) of a refuse incinerator (1), and burned in flat bed combustion in a primary combustion chamber (4). On the other hand, the fluff is burned in suspended combustion in a secondary combustion chamber (7) with a combustion fluff burner (5) for incinerating combustible. Thus, refuse containing much plastics which is formed into fluff can be efficiently disposed of, whereby the amount of incineration is increased as a whole.
