  • Patent number: 6466723
    Abstract: A cleaning tool for cleaning optical fiber connectors exposes a cleaning sheet in a window of the case. A winding pulley is operable to wind the cleaning sheet upon rotation at a constant pitch. A rotation mechanism, that is operated by a lever, rotates the winding pulley. The case is constructed of a first front plate and a second front plate which are closed off by a perimeter wall along their outer circumference. The case has an open portion in a part of the perimeter wall, and the lever is disposed in the open portion in an inclined orientation.

  • Patent number: 5827436
    Abstract: A mixed etching gas consisting of boron trichloride, a rare gas, and chlorine is used for etching of an aluminum metal film by dry-etching. In the first step, high frequency power is used to etch and remove alloy grains which tend to form residues and to etch an aluminum metal film in an anisotropic mode. Just before the under-layered silicon film is exposed, the frequency power is lowered but is kept higher than the minimum power required for anisotropic etching to enable etching selectivity with respect to the silicon dioxide film to be achieved.
