    摘要: The method of lap-welding of metal plates using a laser beam, wherein at least one of the metal plates is surface-treated, includes putting a metal plate on the other metal plate and forming a gap between the metal plates so that gas generated at the treated surface at the time weld can be dissipated therethrough. A surface-treated first work and a surface-treated second work are placed one on the other and clamped by means of a clamp with an opening of the clamp centered at the location on the first work to be welded. Then a laser beam is directed to the location to form a weld. The beam is then directed near the inner periphery of the opening to form a heated portion so that the heated portion deflects to form a gap through which the gas generated at the treated surface dissipates thereby reducing gas pressure.

    摘要: A solar battery module (40) is constituted by a stack of: a plurality of solar battery strings (30) and bus sections (32) connected to both ends of each of the plurality of solar battery strings (30); flexible resin layers (33a through 33c); and a flexible resin film (34). The flexible resin layers (33a through 33c) and the flexible resin film (34) have, on a light receiving surface side of solar battery cells (20), holes through which the bus sections (32) are each partially exposed. The exposed parts of the bus sections (32) serve as a respective plurality of electrically-connecting means (32a). A solar battery array (41) is constituted by a plurality of solar battery modules (40). The plurality of solar battery modules (40) are electrically connected with each other via the plurality of electrically-connecting means (32a). This makes it possible to achieve a large-scale solar battery array (41) with high mechanical strength.

    摘要: In a protection circuit connected, via lines including an inductance component, to a circuit to be protected, a first transistor is arranged on a path to ground from a connection point of the protection circuit and the line. A second transistor is arranged on a path to ground from a connection point of the circuit to be protected and the line, and extracts, from a connection point, a current corresponding to a current flowing in the first transistor. The first and the second transistors are NPN bipolar transistors having a base and an emitter are commonly connected. A resistor is connected between the base and the emitter of the first transistor, and a diode is connected between the base and a collector.
