A technique for peeling an element manufactured through a process at relatively low temperature (lower than 500° C.) from a substrate and transferring the element to a flexible substrate (typically, a plastic film). With the use of an existing manufacturing device for a large glass substrate, a molybdenum film (Mo film) is formed over a glass substrate, an oxide film is formed over the molybdenum film, and an element is formed over the oxide film through a process at relatively low temperature (lower than 500° C.). Then, the element is peeled from the glass substrate and transferred to a flexible substrate.

The present invention provides a light-diffusive polycarbonate-based resin composition which includes (A) 100 parts by mass of an aromatic polycarbonate resin, (B) 0.01 to parts by mass of a light-diffusing agent, and (C) 0.1 to parts by mass of a styrene-(meth)acrylic ester copolymer, and a light-diffusing plate formed from the composition. The light-diffusive polycarbonate-based resin composition can be injection-molded to form a light-diffusing plate having satisfactory precision in thickness for use in comparatively large liquid crystal displays having a size larger than 20 inches.

The invention discloses an artificial leather manufacturing method adopting TPU (thermoplastic urethane) to plasticize PVC (polyvinyl chloride) and reducing use of a plasticizer. According to the method, 80-90 parts of PVC powder, 3-5 parts of a stabilizer, 50-60 parts of the plasticizer, 10-20 parts of TPU, 2-3 parts of a foaming agent, 5-10 parts of filler and an appropriate quantity of a colorant are mixed uniformly, and an artificial leather product is prepared with a traditional calendering process. PVC and TPU are all polar macromolecules and have good compatibility; the TPU macromolecules contain both soft segments and hard segments, the elasticity modulus of the TPU macromolecules is between that of plastics and that of rubber, the TPU macromolecules can still keep better elasticity in a relatively wide temperature range and further have good performance of low-temperature resistance, solvent resistance, heat resistance and the like; when the TPU is used for plasticizing PVC, the glass-transition temperature of a PVC/TPU blended material is reduced remarkably, the heat resistance is improved, and 30%-40% of the use quantity of a micromolecular plasticizer can be reduced; TPU adopts the macromolecules, is not easy to transfer and has lasting plasticizing effect; besides, polar groups such as epoxy groups, ester bonds and the like in the plasticizer and urethane groups in the TPU macromolecules can form a hydrogen bond or dipole interaction, and accordingly, the transference resistance of the plasticizer is further improved.

The magnetic recording medium is a particulate magnetic recording medium for heat-assisted recording, as well as includes a magnetic layer comprising ferromagnetic powder and binder on a nonmagnetic organic material support and a heat-diffusing layer of higher thermal conductivity than the magnetic layer between the nonmagnetic organic material support and the magnetic layer.

It is provided that a polymer film; a preparation method of the polymer film; and a laminated body used the polymer film. The polymer film is suitable for use in producing a laminate body which comprises a support and a polymer film, and is reduced in foreign-matter trapping and which can be used for supplying film devices using conventional apparatuses for glass substrates or silicon substrates. The polymer film coated with the layer of silane coupling agent, which is suitable for producing a laminate that comprises a support and a polymer film, comprises a silane coupling agent layer formed on at least one surface of the polymer film, wherein the silane coupling agent layer has a three-dimensional surface roughness (Sa) of 5.0 nm or less. The method of efficient for producing the polymer film coated with the above layer is the method for producing without using a vacuum.

An air fuel ratio control apparatus readily satisfies an emission requirement and is particularly preferable for small-displacement engines. The air fuel ratio control apparatus for an engine includes a fuel control member disposed in a fuel passage delivering fuel from a fuel metering chamber of a carburetor supplying the fuel to a suction passage of a comparatively small engine such as a general purpose engine, a working machine engine and the like, a combustion gas sensor disposed in an exhaust pipe in the engine, and an electronic control unit. The control unit actuates the fuel control member in response to a concentration of a combustion gas component in an exhaust gas detected by the combustion gas sensor so as to control a fuel flow rate.
