Abstract: A motor-driven compressor includes an inverter device. The inverter device includes a common mode choke coil. The common mode choke coil includes an annular core, two windings wound around the core, and an annular conductor that covers the two windings. The conductor is divided into a first metal plate and a second metal plate, which are combined to form an annular shape such that induced current flows in a circumferential direction of the conductor so as to hinder changes in leakage magnetic flux from the core. The second metal plate is thermally connected to the housing. The first metal plate is thermally connected to the second metal plate. At least one of an electrical resistance value or a thermal resistance value in a current path of the induced current is lower in the second metal plate than in the first metal plate.

Abstract: This is to provide a composition for delivering a nucleic acid and a nucleic acid-containing composition which ensure stability of a nucleic acid drug, have a high intracellular introduction rate, can efficiently express the function of a nucleic acid drug, and have low cytotoxicity. Disclosed is a composition for delivering a nucleic acid and a nucleic acid-containing composition each comprises a block copolymer in which a polyethylene glycol segment and a hydrophobic polyester segment are linked, and a peptide having 4 to 30 residues containing at least one selected from the group consisting of arginine and lysine.

Abstract: A process liquid feed mechanism includes a fixed cylinder with a thread around a peripheral surface, a movable cylinder provided coaxially with the fixed cylinder, a process liquid feed tube and an operating rotator. The movable cylinder is screw-engaged to the fixed cylinder. The process liquid feed tube is fixed in an axial position relative to the movable cylinder and passes through the lid and a cylinder including the fixed cylinder and the movable cylinder to be axially movable relative to the cylinder. The operating rotator includes an annular portion provided coaxially with the movable cylinder. An engaging portion and an engaged portion, which are provided in the movable cylinder and the annular portion respectively, rotate the movable cylinder through engagement therebetween with rotation of the operating rotator and release the engagement as a torque on the movable cylinder increases.
