  • Patent number: 9690193
    Abstract: Disclosed is a curable composition for nanoimprinting, which includes one or more polymerizable monomers, in which one or more monofunctional radically polymerizable monomers occupy 90 percent by weight or more of the one or more polymerizable monomers, and the one or more monofunctional radically polymerizable monomers give a polymer having a glass transition temperature of 25° C. or higher. The one or more monofunctional radically polymerizable monomers are preferably at least one compound selected from (meth)acrylic ester compounds, styrenic compounds, and vinyl ether compounds.

  • Publication number: 20150298365
    Abstract: Provided is a method for producing a microstructure that enables continuous transfer with good mold releasability even without subjecting the mold to a surface release treatment. The method for producing a microstructure according to the present invention includes preparing a mold having a relief-patterned surface. A substrate is separately prepared. A liquid photocurable transferable material layer is formed and sandwiched between the substrate and the mold to be shaped. The shaped transferable material layer is exposed to be converted into a photocured layer. The photocured layer is demolded from the mold to give the microstructure. The mold is prepared from a siloxane-bond-containing polymeric organic compound. The transferable material layer is formed from a photocurable composition including a cationically polymerizable compound (A) and a photoacid generator (B).

  • Patent number: 5247165
    Abstract: A displacement detecting apparatus comprises a non-contacting sensor for detecting a displacement of a measured surface, a linear scale unitarily attached to the non-contacting sensor through a coupling member, a graduation read-out device for reading out a graduation of the linear scale, an actuator for moving the non-contacting sensor and the linear scale, and a servo control circuit for driving the actuator, wherein the linear scale and the non-contacting sensor are moved by the actuator in unison with each other. Thus, the displacement of the measured surface can be detected with high accuracy.

  • Patent number: 4765275
    Abstract: Improved methods for the storage for transport of nematodes. In one form the invention provides a method of storing entomopathogenic nematodes wherein a cream of infective juvenile entomopathogenic nematodes is mixed with an adsorbent and stored under conditions in which microbial growth is inhibited. In another form the invention provides a method of storing entomopathogenic nematodes wherein a cream of infective juvenile entomopathogenic nematodes is stored under substantially anerobic conditions.
