Publication number: 20140275319Abstract: Provided is an active-energy-radiation-curable inkjet recording ink that experiences reduced repulsion when ejected onto nonabsorbent substrates, that has good curability, and that causes little color mixing between uncured coatings formed adjacent to each other by ejecting inks and can thus form fine images on nonabsorbent substrates. The present invention provides an active-energy-radiation-curable inkjet recording ink containing a pigment, a silicone acrylate, an active-energy-radiation-curable compound other than the silicone acrylate, and a radical polymerization initiator. The silicone acrylate is a particular organically modified silicone acrylate including a side chain containing a polyoxyalkylene having a (meth)acryloyl group at an end thereof. The active-energy-radiation-curable compound is a compound (E) having a (meth)acryloyl group and a vinyl ether group.Type: ApplicationFiled: October 26, 2012Publication date: September 18, 2014Applicant: DIC CORPORATIONInventors: Tomokazu Yamada, Yuichi Chisaka, Kazunari Kawai, Yoshitaka Kiuchi

Patent number: 5438860Abstract: In a cutter bit abrasion detecting device of a shield excavator comprising a plurality of cutter bits arranged on the front surface of a cutter head rotatably provided in front of a shield body for excavating a working place, a sensor hole or sensor holes are formed in each of some of the cutter bits and sensor heads each comprising a U-shaped single-core optical fiber accommodated in a casing are inserted thereinto. As a result, sensor heads can be thin to be easily inserted into the sensor holes having a small diameter so as to be set in cutter bits with ease since the single-core optical fiber is employed and the attenuation of light received by the sensor head can be reduced due to the attenuation of light between a reflector plate and the optical fiber since no reflector plate is employed, so that accuracy in detection is improved.Type: GrantFiled: September 13, 1993Date of Patent: August 8, 1995Assignee: Kabushiki Kaisha Komatsu SeisakushoInventors: Kazunari Kawai, Hiroshi Miura
