  • Patent number: 9969175
    Abstract: Provided is a liquid container that is able to prevent or suppress spilling of a liquid that is poured into an opening part. An ink cartridge has a first wall part defining a rear end of the ink cartridge and a second wall part extending on a forward side +X from an upper edge of the first wall part. An ink inlet port that receives ink for refilling is formed in the second wall part. Ink is poured into the ink inlet port from the first wall part side. The ink inlet port has a length dimension in the front-rear direction X that is longer than in the width direction Y, and thus readily receives ink that is poured therein.

  • Patent number: 9163327
    Abstract: Provided is a silicon wafer which is stabilized in quality exerting no adverse influence on device characteristics and manufactured by restricting a boron contamination from the environment, and a manufacturing process therefor. Concretely, the silicon wafer is characterized by an attached boron amount thereon being 1×1010 atoms/cm2 or less. In order to manufacture such a wafer as contains a small amount of boron attached on the wafer surface, the wafer is treated in an atmosphere of boron concentration of 15 ng/m3 or less. Boron-less filters and boron adsorbing filters are used as filters in a clean room and the like so as to lower the boron concentration in the atmosphere.
