    摘要： Photoresist compositions, which can attain high-accuracy etching without causing separation and flexible printed wiring boards prepared with the photoresist compositions are disclosed. In order to etch a polyimide precursor layer on a conductive circuit, a photoresist composition comprising a photopolymerizable organic material (A), a water-soluble resin (B) and an amino-group-containing resin (C) is applied on the surface of the polyimide precursor layer to form a photoresist layer. Then, the photoresist layer is patterned by a photolithographic process. The polyimide precursor layer is etched and the pattern of the photoresist layer is transferred to the polyimide precursor layer. The amino-group-containing resin (C) in the photoresist layer is combined with an acid anhydride in the polyimide precursor layer to attain good adhesion and high-accuracy etching without causing separation of the photoresist layer. Alternatively, a film can be formed from the photoresist composition and then be applied on the surface of the polyimide precursor layer to form a photoresist layer.

    摘要： A flexible printed board is which has increased bonding strength, with which dispersion of the bonding strength can be prevented, the quality of which can be uniformed, with which curling can satisfactorily be prevented, which exhibits excellent dimensional stability and with which a precise circuit can satisfactorily be formed. A flexible printed board has a copper foil on which first and second polyimide-resin layers are sequentially laminated. The first polyimide layer made contact with the copper foil is formed by forming, turning into an imide, a polyimide precursor which contains polyamic acid components prepared owing to reactions of acid anhydride and amine and polyimide components prepared owing to reactions of acid anhydride and isocyanate.

    摘要： A convenient method for nucleic acid analysis is provided, which enables 1000 or more types of nucleic acid to be analyzed collectively with high comprehensiveness and with a dynamic range of at least four digits. In particular, provided is a very effective analytical method especially for untranslated RNAs and microRNAs, of which the types of target nucleic acids is 10000 or lower. Nucleic acids can be analyzed conveniently and rapidly with high comprehensiveness and quantitative performance at single-molecule sensitivity and resolution by following the steps of: preparing a group of target nucleic acid fragments one molecule at a time and hybridizing the nucleic acid molecules, which have known base sequences and have been labeled with the fluorescence substances, with the group of the target nucleic acid fragments to detect the fluorescence substances labeling the hybridized nucleic acid molecules.

    摘要： An apparatus includes a display that displays data; a memory that stores the data and a display condition for displaying the data; and a processor. The processor determines whether the display condition is satisfied in accordance with a change of status of the apparatus. The processor displays the data in response to determining that the display condition is satisfied. The processor obtains, via a network at a timing represented by information that is stored in association with the data, update information to update the at least one of the data and the display condition stored in the memory. The update information obtained via the network includes information indicative of a next update time. The processor obtains, based on the next update time, next update information via the network.
