A UV-curable composition for optical discs contains a fluorine-containing UV-curable resin having a poly(perfluoroalkylene ether) chain and a UV-curable group. The fluorine-containing UV-curable resin exhibits good compatibility with the composition and satisfactorily localizes in and near a surface of a coating film. Thus, the composition can be used to form an outermost layer of an optical disc such that the droplet size of grease such as that constituting fingerprints adhering to the outermost layer is reduced and scattering of light having a short oscillation wavelength passing through the outermost layer is suppressed. Accordingly, an optical disc on and from which signals can be satisfactorily recorded and read is formed.

The present invention provides an ultraviolet-curable composition that inhibits deterioration of a reflective layer during environmental changes in humidity and temperature even when using silicon or a silicon compound for the light reflecting layer, and an optical disc enabling preferable reading and writing of recording signals even during environmental changes in humidity and temperature.In particular, occurrence of deterioration at the interface between a cured coating film of an ultraviolet-curable composition and a silicon reflective layer can be decreased and the formation of minute white'spots, for which there is the risk of impairing reading and writing of signals, can be effectively inhibited even in a high-temperature and high-humidity environment by using an ultraviolet-curable composition comprising a (meth)acrylate oligomer, a (meth)acrylate monomer and an antioxidant, wherein the antioxidant is an antioxidant having an isocyanuric acid backbone, and the chlorine content in the composition is less than 120 ppm.

A sample tube of a sampling valve is moved up and down by a cylinder. When the sample tube is moved downward, a sample inlet opposes a stored sample, and the sample can be extracted. When the sample tube is moved upward, the sample inlet opposes a cleaning liquid path. Thus, cleaning liquid is fed into the cleaning liquid path from a cleaning liquid supply port of a cleaning pipe. The cleaning liquid flows within the sample tube from the sample inlet, and flows out from a sample discharge port. Thus, an entire interior of the sample tube can be cleaned. In a sample extracting device using the sampling valve, a state in which no air or impurities are mixed in the sample can always be maintained, such that stable extraction can be carried out.

Herein disclosed is a semiconductor memory device, in which peripheral circuits are arranged in a cross area of a semiconductor chip composed of the longitudinal center portions and the transverse center portions, and in which memory arrays are arranged in the four regions which are divided by the cross area. Thanks to this structure in which the peripheral circuits are arranged at the center portion of the chip, the longest signal transmission paths can be shortened to about one half of the chip size to speed up the DRAM which is intended to have a large storage capacity.
摘要:
Predetermined wiring of copper is formed on the upper surface of an elongated base film in a wiring forming area as a width-directional central portion of the base film. Further, band-shaped first reinforcing layers of copper are formed on width-directional opposite portions of the upper surface of the base film. As a result, even if the base film has a relatively thin thickness, portions of the base film near sprocket holes can be made to have a substantially desired strength. To keep the first reinforcing layers out of contact with the pins of a transfer pin roller, opening slightly larger than the sprocket holes are formed in the first reinforcing layers.

An electroluminescent panel is provided in a region of the rear surface side of the display panel, which corresponds to a display region, and the drive circuit for the display panel is located in the other region than the display region, on the surface side of the display panel. Further, the inverter serving as a drive circuit for the electroluminescent panel is provided in the region of the rear surface side of the display panel, other than the display region. With this structure, the downsizing and thinning of the display device are promoted.
