  • Patent number: 10944236
    Abstract: A circuit conductor is provided on a base. A semiconductor laser is connected to the circuit conductor. Cutout parts on which the circuit conductor is not formed are provided at, for example, the vicinity of the four corners of the base, and a hole is provided at each of the said portions. The holes penetrate the base. Fixing members are inserted through the holes. The fixing members are, for example, male threads. Since the head part of the fixing members is located in the cutout part, the fixing members and the circuit conductor are not in contact with each other. A platform has holes formed at portions corresponding to the holes in the optical unit and female threads formed on the inner surface. The fixing members and the platform are therefore joined. As a result, the optical unit is fixed to the platform.

  • Patent number: 9073308
    Abstract: The piezoelectric element includes first and second sheets 30 and 40 that are stacked and burned. In this stacked state, a second electrode 60 is located on a first long side 30a having a first non-electrode region 51. Thus, before a conductive film 100A is formed, the end face of a first electrode 50 and the end face of the second electrode 60 are exposed on lateral surfaces 20b and 20d on the same side and can be observed thereon. Slits 91 are formed at certain intervals in a lengthwise direction X. The conductive film 100A is formed so as to apply a voltage between the second electrode 60 exposed on a front surface 20a and ends 20ab and 20ad, thereby driving the piezoelectric element only with connection from the front surface 20a.
