  • Patent number: 7598090
    Abstract: A biosensor is provided with an area in which a reagent having bleaching action is carried in a state where it can be dissolved, at least in a part of a sample application area to which an inspection target solution is applied or the downstream of the sample application area in the direction of the inspection target solution permeating, in a development layer. In the so-constituted biosensor, a colored component in the inspection target solution can be faded by the bleaching reagent, so that the color in parts other than a reactive area is reduced in consequence, whereby a visual judgment is possible and a more accurate measurement result in which a reading error by a measuring device is extremely suppressed can be obtained.

  • Patent number: 6703094
    Abstract: A charging member includes a conductive mandrel, a semiconductive foamed elastic layer provided on the periphery of the mandrel, and a functional double-layer film provided on the periphery of the semiconductive foamed elastic layer. The semiconductive foamed elastic layer is a layer formed by making the mandrel and a semiconductive rubber composition standing uncured and unfoamed pass through a crosshead die of an extruder to set the composition on the periphery of the mandrel, followed by curing and foaming. The semiconductive rubber composition has a Mooney viscosity of from 15 to 30 and has a curing percentage of 40% or less when the foaming pressure reaches 50%. The functional double-layer film is a double-layer tube having a thin layer such that a tube formed out of only the layer is hard to use for covering. Also disclosed are a process cartridge and an electrophotographic apparatus which have such a charging member.

  • Publication number: 20030231611
    Abstract: In a communications network where first and second communication terminals are interconnected via a common communication medium such as a local area network, the terminals jointly establish an infrared light private communication link if they are brought close to each other. The first and second terminals communicate their network addresses to each other either via the local area network or via the private communication link, and establish a session between the communicated network addresses via the local area network if the strength of the infrared-light private communication link at the receiving end is higher than a decision threshold..
