摘要:
A method of bonding a piezoelectric element and an electrode, including the steps of forming a first coating of a material selected from the group consisting of Au, Al, Zn, Cu, and Sn on a bonding surface of the piezoelectric element, and forming a second coating of a material selected from the group consisting of Au, Al, Zn, Cu, and Sn on a bonding surface of the electrode. The combination of the materials of the first and second coatings is preferably Au/Au, Au/Al, Zn/Cu, or Sn/Cu. The method further includes the step of bringing the first and second coatings into close contact with each other and heating them under pressure to form a metallic bond or intermetallic compound between the first and second coatings, thereby bonding the piezoelectric element and the electrode.

摘要:
A processing head is supported for pivotal movement around a pivot point in a processing apparatus. An urging member applies an urging force to the processing head at the pivot point. The processing apparatus allows establishment of point contact between the urging member and the processing head. When the surface of an object inclines from a predetermined attitude, the processing head is allowed to follow the inclination of the surface. The processing head is allowed to establish a predetermined attitude relative to the surface of the object. The processing head thus reliably enables a predetermined action to the object as desired.

A method of assembling a micro-actuator is provided in which a base frame having a plurality of actuator bases is placed on a stage, a first adhesive is applied to each of the actuator bases, and a base electrode frame having a plurality of base electrodes is placed on the first adhesive. The first adhesive is semi-cured by heating and pressing. A second adhesive is applied to each of the base electrodes, and a plurality of piezoelectric elements are placed on the second adhesive. The second adhesive is semi-cured by heating and pressing. A third adhesive is,applied to the piezoelectric elements, and a movable electrode frame having a plurality of movable electrodes is placed on the third adhesive. The third adhesive is semi-cured by heating and pressing. Next, a fourth adhesive is applied to each of the movable electrodes, and a hinge plate frame having a plurality of hinge plates is placed on the fourth adhesive. The fourth adhesive is semi-cured by heating and pressing. Finally, the adhered laminate thus obtained is placed in a heating furnace, and is heated at a predetermined temperature for a predetermined period of time, whereby each of the adhesives is fully cured.

摘要:
A first plate material is set on a work stage. The first plate material includes first components commonly connected to a first connection member. A second plate material is subsequently set on the work stage. The second plate material includes second components commonly connected to a second connection member. The second components are superposed on the corresponding first components. The first components as well as the second components can be handled as a one-piece component. It leads to an improved productivity. Heat surfaces of a heat block contact the second components. The connection members are prevented from thermal expansion. The constant intervals are reliably maintained between the adjacent first components and the adjacent second components.

摘要:
A body has a configuration in which a first ellipse has a first and second focal points and a second ellipse having a third and fourth points are arranged such that the second and third focal points coincide. This body is equivalent to an optical system having an optical path in which light gathered to the first focal point passes through the first focal point, and is reflected by a first concave reflecting surface, being a part of the first ellipse, to go through the second focal point, and then reflected by a second concave reflecting surface, being a part of the second ellipse, to be gathered to the fourth focal point.
