  • Patent number: 9107274
    Abstract: Provided is a color display element which employs a conventional system of monochrome electronic paper without degrading the degree of brightness and with ease and lower costs. Also provided is a method of producing a color display element including a pair of opposing substrates having electrodes, charged display bodies of white color and black color which are enclosed between the opposing substrates, and a color filter which is disposed on one of the opposing substrates, the method including forming a color filter disposed on a viewing side by forming, first, colored regions of at least three colors of blue, green, and red by an inkjet method on a transparent support substrate, and forming remaining regions other than the colored regions so as to be colorless or transparent.

  • Publication number: 20080225438
    Abstract: A laminate (20) for a suspension comprises a stainless steel foil (11), and an insulating layer (12) and a conductor layer (13) that are stacked in this order on the stainless steel foil (11). The stainless steel foil (11) contains a martensite phase in a volume fraction of 0.4 to 2.5 volume %. The insulating layer (12) is made of a polyimide resin, for example. The conductor layer (13) contains pure copper or a copper alloy, for example. The laminate (20) for a suspension is used for producing a wiring-integrated suspension that flexibly supports a slider including a magnetic head such that the slider is opposed to a recording medium.
