摘要： The invention provides a solder alloy of Sn, Sb, Ag and Cu, wherein the Sb is about 1.0-3.0 wt %; the Ag is about 1.0 wt % or more and about 2.0 wt % or less; the Cu is about 1.0 wt % or less; and the remainder is Sn. The solder alloy has a comparatively low Young's modulus and sufficient tensile characteristics. Therefore, it resists peeling from the bonded electrode, etc., even though a heat stress is added. Also, a solder which has an excellent solderbility to metal phases such as Cu and Ni can be provided. Therefore, a solder alloy excellent in thermal shock resistance can be provided. The solder alloy may be used for soldering the inside of an electronic component.

摘要： A parallel type piezoelectric bimorph vibrator is used for a piezoelectric buzzer or a piezoelectric loud-speaker, which is cemented at both ends of a conductive diaphragm together with piezoelectric elements, and is provided at part of the outer periphery of a diaphragm with a cutout, the outer peripheries of the piezoelectric elements facing the cutout. Electrodes outside both the piezoelectric elements are connected by a conductor at the position corresponding to the cutout, so that the existence of the cutout prevents the conductor from being brought into contact with the diaphragm.

摘要： An insert terminal containing case includes a bottom wall, four side walls, and an opening at the upper portion, wherein a terminal made of a metal plate is vertically fixed to at least one of the four side walls by insert molding. A groove is vertically arranged at the outer side surface of the side wall fixing the terminal, the groove extending downward, the outer side surface of the terminal is partially exposed at the groove, and the inner side surface opposite the outer side surface of the terminal exposed at the groove is partially exposed at the inner side surface of the side wall. Therefore, when the terminal is provided in the case by insert molding, molding can be performed only using upper and lower dies. Furthermore, the terminal can be reliably exposed at the inner surface of the side wall. The insert terminal containing case has the minimum difference between the opening dimension of the case and the dimension of a piezoelectric diaphragm and is molded without using a sliding die.

摘要： A piezoelectric electroacoustic transducer includes a piezoelectric diaphragm having a substantially rectangular shape which vibrates in the thickness direction when an alternating current is applied between electrodes of the piezoelectric diaphragm, a housing which stores the piezoelectric diaphragm, and a pair of terminals formed in the housing by insert molding. One end of each terminal is inserted inside the housing and includes a body portion fixed to the housing and wing portions which extend from both sides of the body portion toward the corners of the housing. The wing portions are not fixed to the housing, and stress-relieving portions are disposed between the body portion and the wing portions so that the wing portions are able to move toward the inside of the housing. Each electrode of the piezoelectric diaphragm is connected to at least one of the wing portions of the terminals by a conductive adhesive.
