摘要:
A biasing spring is interposed between a coupling plate and a covering section while being compressed from its natural length. The biasing spring biases, by its resilient force, a lens unit toward a −Z side to bring a surface of the lens unit at the −Z side into contact with an abutment portion of a fixing frame section. When a temperature of an actuator is equal to or lower than a predetermined temperature, a biasing force of the biasing spring surpasses a force generated in the actuator, and thus the lens unit is not moved. When the actuator is heated up to a temperature equal to or higher than the predetermined temperature, the lens unit is continuously moved in the +Z direction. Thereby, movement of a lens due to a change of an environmental temperature can be prevented.

A driving mechanism, a driving device, and a lens driving device includes a lever member. The lever member includes an arm portion for surrounding a part of a driven member in a side direction. The arm portion has a plurality of displacement output portions to be engaged with the driven member. The lever member is constructed in such a manner that a displacement amount of the displacement output portions in a predetermined first axis direction is set larger than a displacement amount of a displacement input portion to be generated by input of a moving force to be applied by a shape memory alloy actuator. The driving mechanism, the driving device, and the lens driving device enable to obtain a large displacement amount with a reduced size and a reduced weight, and stably move the driven member.

A service provider makes requests to an information processing center for processing for an IC card in card command units. The information processing center issues encrypted card commands that can be interpreted by the IC card itself based on requests received from the service provider and sends these to the IC card via the computer network, client, and card reader/writer device. This enables an IC card connected to a client to be accessed using secure communication.

In a friction drive actuator 1 according to the invention, a rotor 2 and a stator 4 are held in contact at a plurality of positions by a plurality of vibrators 3, and at least one of the vibrators 3 vibrates to rotate the rotor 2 relative to the stator 4. Accordingly, the rotor 2 is supported without using a bearing and, hence, the rotor 2 can be more easily elastically deformed as compared with the case where the rotor 2 and the stator 4 are held in contact over the entire circumference. Therefore, a frictional force between the stator 4 and the rotor can be stabilized.

In a truss type actuator having two piezoelectric devices provided for crossing at right angle and driven by two alternating driving signals having a predetermined phase difference between them for driving a chip member along a predetermined elliptic trail (including a circular trail). The piezoelectric devices are contacted by protrusions having a high rigidity and formed on contacting faces of the chip member and a base member for holding the piezoelectric devices, and fixed by adhesive having a low rigidity and filled around the protrusions. Thereby, one of the piezoelectric device hardly receives a reaction force from another piezoelectric device due to the displacement thereof.

The disclosure describes a double folding type of seat, wherein a panel for at least a seat cushion is molded in a synthetic resin material, and at the same time, hinge male parts of the hinge mechanisms are formed integrally into the molded cushion, and thus decreases the number of parts, reduces the weight, and improves the assembling performance. In particular, the seat includes a reinforcement panel 4 for a seat cushion 2 or seat back 3 being molded in a synthetic resin material, and additional parts for the reinforcement panel being integrally formed.
