Abstract: The laminate according to the invention is comprised of a base material (A), a silicon-containing layer (B) and a polymer layer (C) obtained from an organic acid metallic salt having a polymerizable group. The silicon-containing layer (B) and the polymer layer (C) are sequentially laminated over at least one surface of the base material (A), the silicon-containing layer (B) includes a high nitrogen concentration region comprised of silicon atoms and nitrogen atoms, silicon atoms and nitrogen atoms and oxygen atoms, or silicon atoms and nitrogen atoms and oxygen atoms and carbon atoms. The high nitrogen concentration region is formed by irradiating energy ray onto a polysilazane film formed over the base material (A) under an oxygen concentration equal to or lower than 5% and/or a relative humidity at room temperature (23° C.) equal to or lower than 30% so as to denature at least a part of the film.

Abstract: The present invention aims to provide a transparent gas barrier film having excellent gas barrier properties against oxygen, water vapor and the like especially under high humidity, and showing excellent delamination resistance after hydrothermal treatment. The present invention relates to a gas barrier film comprising: a base film having an inorganic compound layer formed on one side thereof; and a (meth)acrylic silane coupling agent layer and a layer (Y) that are laminated in this order on the inorganic compound layer, which layer (Y) comprises a polymer of a polyvalent metal salt of an unsaturated carboxylic acid compound (a) and a vinyl alcohol polymer (b).

Abstract: Disclosed is a polishing slurry which enables to suppress damages to an under layer while securing an adequate polishing rate. The polishing slurry contains a resin (A) having an amide group and an organic resin (B).

Abstract: Disclosed is a polishing composition containing not less than 1 wt % of a water-soluble resin, which is obtained by polymerizing a vinyl monomer containing an amino group and/or an amide group, based on the total weight of the polishing composition.

Abstract: The characteristics of thin-film magnetic heads are evaluated by measuring, in a step and repeat method and apparatus, the magnetic field generated by the respective heads in a bar including multiple heads.

Abstract: The lithium ionic conducting glass thin film of the present invention comprises a glass containing 20 to 80 mol % of an Li.sub.2 O component. This glass thin film has a dense structure which shuts off gas and can be used as a solid electrolyte in a carbon dioxide sensor.The thin carbon dioxide sensor of the present invention comprises the above lithium ionic conducting glass thin film as a solid electrolyte. This sensor enables complete elimination of noise attributed to gas permeation by virtue of the lithium ionic conducting glass thin film having a dense structure with the result that the accuracy of carbon dioxide concentration measurement can be enhanced. Further, the lithium ionic conducting glass is formed into a thin film, so that the sensor has a low internal resistance, acts at low operating temperatures and exhibits a high response speed.
