Abstract: 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.

Abstract: In the state in which a FPC terminal conductor precoated with a solder bump is opposed to a suspension terminal conductor having an Au plating layer, heating and melting is carried out while the suspension terminal conductor is pressed against the solder bump by a heater chip, thereby joining the FPC terminal conductor with the suspension terminal conductor by solder without using flux. In the suspension terminal conductor, a notch, a slit, or the like is formed as a solder joint observation window through which the solder joint state by the solder bump can be visually checked from outside via an insulating layer.

Abstract: 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.

Abstract: In a method of producing a micro-actuator, a first adhesive is applied to a movable plate, and a movable, and a movable electrode is placed on the first adhesive. A second adhesive is applied to the movable electrode, and a piezoelectric element is placed on the second adhesive. Next, a third adhesive is applied to an actuator base, a base electrode is placed on the third adhesive, and the third adhesive is semi-cured in the same manner as above. A fourth adhesive is applied to the base electrode, the piezoelectric element is placed on the fourth adhesive, and the fourth adhesive is semi-cured in the same manner as above. Finally, the adhered laminate thus obtained is placed into a heating furnace and heated at a predetermined temperature for a predetermined period of time to thereby fully cure the adhesives.

Abstract: 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.

Abstract: 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.
