摘要:
A polyimide film for production of a wiring board having a metal wiring, which is formed by forming a metal layer on one side (Side B) of the polyimide film, and etching the metal layer; the polyimide film is curled toward the side (Side A) opposite Side B; and the curling of the polyimide film is controlled so as to reduce the drooping of the wiring board having a metal wiring formed thereon. The handling characteristics and productivity in IC chip mounting may be improved by the use of the polyimide film.

A modified polyimide resin favorably employable for manufacturing an insulation film of an electric-electronic device is composed of recurring units (I) derived from a biphenyltetracarboxylic acid compound, a diamine compound, and a monoamine compound having at least one hydroxyl group and recurring units (II) derived from diisocyanate and polybutadiene having hydroxyl group at each terminal, which optionally contains further recurring units (III) derived from diisocyanate and a compound having hydroxyl group at each terminal and further having a reactive substituent.
摘要:
A display unit includes a transparent hollow tube member, and a display liquid sealed in the transparent hollow tube member. The display liquid includes a liquid and at least one kind of charged or non-charged particle dispersed in the liquid. An image formed by a display device including the display units is kind to the eye in the same way as printed matter, and does not cause eyestrain due to flickering of emitted light.
摘要:
A polyimide complex sheet is composed of an aromatic polyimide film, an intervening layer and a thin metal oxide layer in which the intervening layer is formed of a mixture of the metal oxide and the aromatic polyimide under such condition that a ratio of the metal oxide to the aromatic polyimide increases from a side facing the polyimide film to a side facing the metal oxide layer and the intervening layer is united to the polyimide film and the metal oxide layer under such condition that the metal oxide layer is not peelable from the polyimide film without breakage of the metal oxide layer.
摘要:
A near-field optical recording medium comprises a recording layer capable of writing, reading and erasing information using an evanescent light, the evanescent light having a beam spot size smaller than the wavelength of a source light, wherein the recording layer is a stable amorphous layer mainly comprising a photochromic compound having a glass transition point of 55° C. or higher and a molecular weight of 3000 or less.

摘要:
The sterilizing method according to the present invention is a method of sterilizing a medical product by a hydrogen peroxide gas while keeping the packaged condition. In such a sterilizing method, a packaging container (1) capable of allowing the hydrogen peroxide gas to penetrate therethrough is used, and after completion of the sterilizing treatment, the packaging container (1) is subjected to degassing treatment while heating, thereby removing the hydrogen peroxide gas from the inside thereof. As a result, it is possible to conduct the treatment efficiently and surely prevent the hydrogen peroxide gas from remaining in the packaging container. In addition, the injection packs (P) according to the present invention comprises the packaging container (1) and a medicine-filled injector (4) enclosed in the packaging container. In the injection packs (P), a container body (2) has such a specific shape which can ensure a sufficient gas-penetrating area of a sterile paper by which the container body is sealed, when the injection pack are stacked up in multiple stages. Accordingly, upon the treatment, it becomes possible to penetrate the hydrogen peroxide gas into the packaging container (1) for a short period of time and degas the packaging container (1) for removing the hydrogen peroxide gas from the inside thereof.
