A vibration actuator includes: a movable body including a core around which a coil is wound in a state in which a tip part of the core is exposed; a fixed body including one or more magnets disposed away from and facing the tip part of the core; and a shaft part rotatably supporting the movable body on a side of a base end part of the core, and generates vibration by oscillation of the tip part of the core around the shaft part with respect to the one or more magnets by cooperation among the coil, the core and the one or more magnets.

Vibration actuator with movable body with tip part of the core oscillating and a shaft part supporting the movable body on a side of a base

A vibration actuator, includes: a movable body including a magnet; a fixing body including a coil; and an elastic support portion supporting the movable body, in which: the fixing body includes: a first fixing body disposed on one side of a vibration direction so as to cover the movable body, and a second fixing body that is bonded to the first fixing body and being configured to accommodate the movable body in such a way that the movable body is capable of vibrating, in which: the elastic support portion is a plate-shaped elastic body that includes one end portion fixed to the movable body and is provided to protrude from an outer periphery of the movable body in a radial direction, and another end portion of the elastic support portion is fixed while being sandwiched between the first fixing body and the second fixing body.

Vibration actuator

A vibration actuator has a movable body including a magnet, a fixing body including a coil, and an elastic support portion. The movable body vibrates in a magnetization direction of the magnet in cooperation with the coil to which power is supplied and the magnet. The fixing body has a peripheral wall portion that is disposed to surround the movable body in a direction intersecting the magnetization direction. The elastic support portion is a plate spring which has one end portion fixed to an outer periphery of the movable body opposing an inner surface of the peripheral wall portion and the other end portion fixed to the peripheral wall portion and is disposed in a radial direction from the outer periphery of the movable body. The one end portion of the elastic support portion is bonded by a fixing portion provided in the movable body.

A magnetic tape recording/reproducing apparatus is disclosed that selectively loads a first tape cassette accommodating a first magnetic tape or a second tape cassette accommodating a second magnetic tape having a width greater than the width of the first tape. The apparatus includes a rotating drum unit including a lower stationary drum and an upper rotating drum, and a loading mechanism that, if the first tape cassette is loaded, pulls the first magnetic tape out of the first tape cassette and winds it onto the rotating drum unit through a first winding angle so as to form a first tape path and, if the second tape cassette is loaded, pulls the second magnetic tape out of the second tape cassette and winds it onto the rotating drum unit through a second winding angle greater than the first winding angle so as to form a second tape path.

Magnetic tape recording/reproducing apparatus

Performing power saving control which can be inherited and standardized easily, and which keeps power devices from having to become larger is made possible. A current In flowing through an electrical path is detected as a voltage Vs by a current detection section, and is outputted as a voltage Vout by an amplifying section. When a level corresponding to the voltage Vout exceeds a limit level, a power limit detection section outputs a power limit detection signal. When a controller receives the power limit detection signal via a detection signal holding section, the controller outputs a throttle control command signal. When a chip set receives the throttle control command signal, the chip set initiates throttle control that lowers the clock frequency of a CPU. The present invention may be applied to laptop personal computers.

Information processing apparatus and method, as well as program

A rotary head drum apparatus includes a stator drum. A rotary drum is provided with a plurality of magnetic heads and rotates the magnetic heads. The rotary drum is mounted for rotational movement with respect to the stator drum. A rotary transformer includes a stator-side rotary transformer provided on the stator drum and a rotating-side rotary transformer fixed to the rotary drum. The stator-side rotary transformer and the rotating-side rotary transformer are adapted to send and receive signals to each other. An adhesive providing gap is disposed between the rotating-side rotary transformer and the rotary drum for receiving an adhesive for bonding the rotating-side rotary transformer to the rotary drum. An adhesive splashing prevention part is provided on the rotating-side rotary transformer and receives adhesive splashing from the adhesive providing gap. The adhesive splashing prevention part includes a first ring member having an opening in the center thereof and bonded to the rotating-side rotary transformer with a thermosetting resin adhesive. A second ring member is bonded to the first ring member with the thermosetting resin adhesive and has in the center thereof an opening whose diameter is smaller than the diameter of the opening of the first ring member. The adhesive splashing prevention part forms a space receiving adhesive splashing from the adhesive providing part.
