  • Patent number: 8159059
    Abstract: The present invention relates to a microelectromechanical device having a simple structure in which strains of the semiconductor substrate can be reduced. Both a semiconductor substrate 17 and a second substrate 14 are disposed to face a first main surface 13a of the first substrate 13 and connected to the first main surface 13a of the first substrate 13. With this structure, no internal line or side surface line is necessary, and the structure of the first substrate 13 can be simplified. The length of the line can be decreased to decrease the resistance of the line, and good electrical characteristics can be achieved at low energy consumption. The strains in the semiconductor substrate 17 can also be reduced.

  • Patent number: 7160820
    Abstract: There is provided a process for preparing a composite material of an oxide crystal film and a substrate by forming a Y123 type oxide crystal film from a solution phase on a substrate using a liquid phase method, wherein problems such as cracking of the oxide crystal film, separation of the oxide crystal film from the substrate, and development of a reaction layer between the substrate and the solution can be minimized. The solvent for forming the solution phase uses either a BaO—CuO—BaF2 system or a BaO—CuO—Ag—BaF2 system, and when the substrate with a seed crystal film bonded to the surface is brought in contact with the solution to form (grow) the oxide crystal film on the substrate, the temperature of the solution is controlled to a temperature of no more than 850° C.

  • Patent number: 6979216
    Abstract: In a connector comprising a housing (11) and a contact (21) held by the housing, the contact is brought into contact with a connection object under a pressing force obtained by operating an operating member (61). An elastic member (71) elastically deformable is interposed between the contact and the operating member. The operating member has a first cam surface (63a) for applying the pressing force to the contact with elastic deformation of the elastic member and a second cam surface (63b) for releasing the pressing force. An insulating actuator (51) cooperating with the contact may be interposed between the contact and the elastic member. The elastic member may be a leaf spring member held by the actuator.
