  • Publication number: 20120001520
    Abstract: An actuator device includes an actuator having one end as a fixed end and the other end as a free end, and bendable when a voltage is applied; and a base member having a fixed section that fixes the fixed end of the actuator. A projecting section is provided at the base member. In a state where the actuator is bent, when a force is applied and the free end is deformed toward a direction that is reverse to the bending direction, the actuator contacts the projecting section. The projecting section is a fulcrum of the displacement and a generating load is capable of being large by the principle of material mechanics without losing the displacement amount.

  • Patent number: 7523524
    Abstract: A second housing whose center portion is depressed and whose end portion around the center portion is formed like a visor is arranged around a first housing whose center portion is depressed and whose end portion around the center portion is formed like a visor, and a hollow portion is formed between the first housing and the second housing by sandwiching a packing between the end portions of the housings. Further, degassed water for preventing empty heating is filled in the hollow portion, and an ultrasonic transducer is placed on the surface of the center portion of the first housing. A weight for preventing the vibration of the wall is provided on the wall surface of the second housing. Since the vibration of the wall of the housing is suppressed by the weight, vibration energy returns toward the bottom surface of the center of the housing through water and is radiated from the bottom surface efficiently as ultrasonic waves.

  • Publication number: 20080075919
    Abstract: To provide a wiring board that permits the formation of a Cu plating layer maintaining sufficient adhesion to both a ceramic layer and a Ag connecting layer and a method for manufacturing the wiring board. [Solving means] Parts of the surface of the ceramic layer 12 and the upper surfaces of the Ag connecting layers 14 are covered with a Ag thin film layer 15. The Ag thin film layer 15 enhances a bonding strength between the Cu wiring layer 11 and the Ag connecting layer 14 and contributes to forming the Cu wiring layer 11 with a sufficient thickness on the ceramic layer 12 during a step of forming the Cu wiring layer 11 by electroless plating.
