摘要:
An actinic energy ray curable adhesive contains a urethane resin (D) and a epoxy resin (E). The urethane resin (D) is prepared by reacting a diol ingredient (A1) having no (meth)acryloyl group, an optional diol ingredient (A2) having no (meth)acryloyl group, no carbonate structure and no alicyclic structure, a polyol ingredient (B) having a (meth)acryloyl group and two or more hydroxyl groups in a molecule, and a polyisocyanate ingredient (C) together. The ingredient (A1) is selected from a diol (a1) having a carbonate structure and an alicyclic structure in a molecule, a combination of a diol (a2) having no alicyclic structure but having a carbonate structure, and a diol (a3) having no carbonate structure but having an alicyclic structure, and a combination of a diol (a1) and at least one of the diol (a2) and the diol (a3).

摘要:
A backside protective sheet (V′) for a solar cell includes an adhesive agent layer (1′) containing an epoxy resin (A), and a plastic film (2) with one main surface supporting the adhesive agent layer (1′). A method of producing a backside protective sheet (V′) for solar cells includes applying an adhesive agent to a main surface of a plastic film (2) to form an adhesive agent layer (1′), the adhesive agent containing an epoxy resin (A), a resin (B) other than epoxy resins, the resin (B) having a hydroxyl group and substantially no carboxyl group, and a polyisocyanate compound (C).
摘要:
An engine control apparatus includes a target air volume calculator which calculates a target air volume required by an engine, and an actual air volume calculator which calculates an actual air volume inhaled into a cylinder of the engine. The apparatus further includes an estimator which calculates the estimated value of subsequent actual air volume on the basis of a time lag from a time when the target air volume is calculated to a time when the actual air volume reaches the target air volume. The apparatus can accurately estimate an intake air volume inhaled into the cylinder to improve the controllability of the engine.
摘要:
Disclosed is a vehicle member that includes a molded body and a protective film disposed on a surface of the molded body and formed by curing of an active energy ray-curing composition. The active energy ray-curing composition contains an active energy ray-curing prepolymer (A) obtainable by a reaction of an acrylic-based prepolymer having a hydroxyl group and an acrylic monomer (a4) having an isocyanate group, an active energy ray-curing compound (B) having a benzotriazole group, another active energy ray-curing compound (C) differing from the (A) component and the (B) component, and inorganic oxide particles (D). The acrylic-based prepolymer having the hydroxyl group is a copolymer that includes an acrylic monomer (a1) having a piperidinyl group, an acrylic monomer (a2) having a hydroxyl group, etc., as monomer units.
摘要:
A relay device that monitors and controls common public radio interface (CPRI) links that are links using CPRIs functioning as interfaces for connecting multiple relay devices included in a radio base station detects a disconnected CPRI link by monitoring, via the CPRI links, relay information containing communication data and control data. The relay device distributes a control content, such as a forced link disconnection that forcibly disconnect a CPRI link or no-transmission that stops the transmission of the communication data, with respect to each CPRI link in accordance with a connecting location of the CPRI link in which a link disconnection is detected. The relay device monitors and controls each CPRI link.
