摘要:
A polyvinyl chloride-based adhesive tape or sheet has a base material layer formed to include 10 to 40 parts by weight of plasticizing agent(s) in relation to 100 parts by weight of a polyvinyl chloride-based resin and an adhesive layer on one surface of the base material layer, the plasticizing agent includes at least one type of plasticizing agent having an SP value of at least 9.0.
摘要:
An object of the present invention is to provide a surface protecting film which dramatically improves an efficiency of transporting and storing a mother glass, has better peelability from an adherend when peeled without polluting a mother glass surface, and gives reinforcing effect, and use thereof, by using a pressure-sensitive adhesive protecting film. There is provided a film for protecting a mother glass for a flat panel display, characterized in that a rear side is unevenly-processed, and a pressure-sensitive adhesive side is smoother than a rear side.
摘要:
An optical disc has a two-step pit structure in which first pits and second pits whose depth is a half of that of the first pits are arranged in superposition in the same track direction. A first laser diode emits first laser light having a first wavelength which is four times the depth of the first pits, and a second laser diode emits second laser light having a second wavelength which is four times the depth of the second pits. An optical system introduces the first and second laser light onto a recording surface of the optical disc, and also introduces reflected light to a detector. A selecting drive mechanism may be provided to select one of the first and second laser diodes as a light source for actually emitting light to be introduced onto the recording surface.

An object of the present invention is to provide a surface protecting film which dramatically improves an efficiency of transporting and storing a mother glass, has better peelability from an adherend when peeled without polluting a mother glass surface, and gives reinforcing effect by adopting a pressure-sensitive adhesive protecting film, and use thereof. This invention relates to a film for protecting a mother glass for a flat panel display having a pressure-sensitive adhesive layer on one side of a film substrate, wherein a surface roughness Ra of the pressure-sensitive adhesive layer is 0.2 μm or smaller, and a surface roughness Rz is 1.0 μm or smaller, and wherein the pressure-sensitive adhesive layer comprises a crosslinked copolymer containing a (meth)acrylic acid ester monomer and a vinyl-based monomer having a functional group as a component, and a glass transition temperature of the copolymer obtained by a Fox's equation is −25 to −10° C.
摘要:
There is disclosed a microscope constitution in which an base including an image pickup device is disposed confronting the underside of a stage portion via an optical portion having a linear optical axis, and a lighting head is assembled/disposed with respect to the stage portion so as to be rotatable/adjustable around two axes different from the optical axis via first and second arms.
