Abstract: A medium clamping device includes a device main unit that includes: a first circularly moving body that has a surface circularly moving and harder than a recording medium; a second circularly moving body that has a surface moving circularly and harder than the recording medium passing between the both surfaces of the two circularly moving bodies; and a load applying section that applies a load to at least one of the first circularly moving body and the second circularly moving body, to sandwich the recording medium by the load with two moving bodies. The medium clamping device further includes: a support section that supports the device main unit and is secured to a fixed body; and an alleviating system that alleviates transmission of a shock from the device main unit to the fixed body and is incorporated in the support section.

Abstract: An photo-curable sealing agent composition comprising (A) an unsaturated group-containing urethane resin having a number average molecular weight of 1,000-100,000 and an unsaturation degree of 0.1-1 mol/kg, which is obtained by reaction of (a) a polycarbonate diol having a number average molecular weight of 500-3,000, (b) a bifunctional epoxy (meth)acrylate having two hydroxyl groups and two ethylenically unsaturated groups, and (c) a polyisocyanate; (B) a (meth)acrylic acid ester monomer, wherein an alcohol residue, ester-bonded with an (meth)acyloyl group, is a hydrocarbon group which may contain an oxygen atom, and has 1-20 carbon atoms and a molecular weight of not larger than 1,000; and (C) a photo-polymerization initiator. The sealing agent composition exhibits a high curability performance and gives a cured product having a low hardness and enhanced flexibility and elongation, and improved physical and mechanical strength and enhanced durability.

Abstract: A packet transfer apparatus is provided with: storage means configured to store a predetermined search pattern and an address identifying a predetermined apparatus; determination means configured to determine whether predetermined data in a packet received from a network interface matches the search pattern; determination means configured to determine a network interface for outputting the packet using the determination result; replacement means configured to replace an address identifying a destination apparatus of the packet with an address identifying the predetermined apparatus when outputting the packet from a network interface connected to the predetermined apparatus; and packet sending means configured to send the packet to the determined network interface.
