The present invention is to provide a weather-resistant adhesive which achieves adhesive property, moist heat resistance and weather resistance in a practical level by means of aging at low temperature and for short time. There is provided a weather-resistant adhesive composition, characterized in containing (A) a polyester polyol having an acid value of 30 to 150 equivalents/106 g and (B) a polyisocyanate compound comprising an aliphatic polyisocyanate compound and/or an alicyclic polyisocyanate compound. Also, there is provided a layered product, characterized in being prepared by laminating films using said composition.
摘要:
A high voltage output driver derives operational power from high voltages and a switching circuit which reverses the output state of the high voltage output driver. The high voltage output driver has in a current path of the high voltages, a series circuit of a first MOS transistor (M1) and second MOS transistor (M2), with the serial connection node thereof being the driver output terminal. The switching circuit operates to reverse the complementary switching states of the first and second MOS transistors such that one transistor in the on-state is switched to an off-state first and the other transistor is switched to an on-state afterward. Even if the other MOS transistor has its Vds exceeding the minimum breakdown voltage when it operates to turn on, the through current path is already shut off, and therefore the high voltage output driver does not break down.

The present invention provides a photocatalyst material, which can comprise a photocatalyst with an excellent adherence to a substrate and a high photocatalytic activity, and a production method thereof. The photocatalyst material (20) obtained by reacting crystal nuclei with a sol solution containing an organic metallic compound or the like and then carrying out gelation, solidification and heat treatment has a structure where more than one basic structures (10) are fixed to the surface of the substrate (1). The basic structure consists of abase portion (2) comprising crystal nuclei fixed to the surface of the substrate (1) and a photocatalyst crystalline body (3), which connects to and is extended from the base portion (2) and has a columnar structure having a hollow portion (5) formed therein. A cylindrical substrate may be used for the substrate (1). The above photocatalytic activity is further enhanced by the formation of an interior-exposing structure (8) in a shell portion (4).

摘要:
A liquid crystal display apparatus includes a liquid crystal panel having a matrix of pixels, a control circuit, and a temperature sensor. The temperature sensor directly or indirectly detects a temperature of the liquid crystal panel. The control circuit reverses a polarity of a voltage applied to each pixel at a time interval variable with the detected temperature, while keeping a field frequency constant. The time interval is a positive integer multiple of the reciprocal of a field frequency, i.e., a positive integer multiple of a field period. When the temperature of the liquid crystal layer is low, the control circuit reverses the polarity of the voltage at a longer time interval. In contrast, when the temperature of the liquid crystal layer is high, the control circuit reverses the polarity of the voltage at a shorter time interval.
摘要:
A magneto-optical recording medium comprises, at least a transparent base plate, a dielectric layer formed on one major surface of the transparent base plate, and a recording magnetic layer formed over the dielectric layer. The dielectric layer may be a single-layer structure consisting of a dense dielectric film or may be a two-layer structure consisting of a porous dielectric film formed contiguously with the transparent base plate, and a dense dielectric film formed contiguously with the recording magnetic layer. The magneto-optical recording medium has high recording magnetic field sensitivity and excellent mechanical properties, and is capable of satisfactorily functioning for recording/reading operation on either a magnetic modulation recording system or an optical modulation recording system.
