摘要： A vibration actuator has a movable body including: a disk-shaped magnet; disk-shaped cores fixed on front and rear surfaces of the magnet and each having an opening at a center thereof; leaf springs having a substantially circular shape; and spring stopper weight parts each having one end positioned by joining the opening to be joined with one of the cores and having another end connected to a central part of one of the leaf springs; and a fixing body including an annular coil having a larger inner diameter than the magnet, the cores and the spring stopper weight parts. The fixing body supports an outer periphery part of the leaf springs and accommodates therein the movable body such that the magnet, the cores and the spring stopper weight parts are capable of moving upwardly and downwardly inside the coil.

摘要： A vibration actuator includes a movable body provided with one of a coil and a magnet that is disposed radially inward of the coil with a gap formed therebetween, a fixing body provided with the other of the coil and the magnet and a shaft portion, and an elastic support portion, the movable body vibrating in a vibration direction by means of cooperation between the coil supplied with power and the magnet. The movable body is provided with a through-hole into which the shaft portion is inserted with a gap formed between the through-hole and an outer peripheral surface of the shaft portion and the elastic support portion supports the movable body such that the movable body does not come into contact with the shaft portion at a time when the movable body does not vibrate and at a time when the movable body vibrates.

摘要： To provide a semiconductor device having a structure in which a barrier metal film containing nitrogen is formed in a connection surface between a copper alloy wiring and a via, in which the electric resistance between the copper alloy wiring and the via can be prevented from rising, and the electric resistance can be prevented from varying. A semiconductor device according to the present invention comprises a first copper alloy wiring, a via and a first barrier metal film. The first copper alloy wiring is formed in an interlayer insulation film and contains a predetermined additive element in a main component Cu. The via is formed in an interlayer insulation film and electrically connected to the upper surface of the first copper alloy wiring. The first barrier metal film is formed so as to be in contact with the first copper alloy wiring in the connection part between the first copper alloy wiring and the via and contains nitrogen. The predetermined additive element reacts with nitrogen to form a high-resistance part. In addition, the concentration of the predetermined additive element is not more than 0.04 wt %.
