    • A protection element is provided which is capable of stably retaining a flux on a soluble conductor at a predetermined position, enabling a speedy and precise blowout of the soluble conductor in the event of an abnormality. This protection element includes: a soluble conductor 13 which is disposed on an insulation baseboard 11 and is connected to a power supply path of a device targeted to be protected, to cause a blowout by means of a predetermined abnormal electric power; a flux 19 which is coated onto a surface of the soluble conductor 13; and an insulation cover 14 which is mounted on the baseboard 11 with the soluble conductor 13 being covered therewith. In addition, the protection element is provided with a protrusive stripe portion 20 which is formed on an interior face of the insulation cover 14 in opposite to the soluble conductor 13 and in which a stepped portion 20a for retaining the flux 19 is formed at a predetermined position while in contact with the flux 19. The soluble conductor 13 has a hole portion 13a at which the flux 19 is retained.

    • In performing an light emitting operation using a plurality of semiconductor light-emitting devices, these semiconductor light-emitting devices are lighted up such that the driving current is lessened and the life time of the devices is prevented from being shortened and lights can be emitted to a remote site without reducing an amount of lights. Semiconductor laser devices 23a to 23c, which emit lights through independent lenses 25a to 25c, are connected in series to each other and connected to a signal generating circuit 24, serving as a power supply, so as to perform pulse lighting, whereby making it possible to light up three semiconductor laser devices simultaneously at a driving current corresponding to one semiconductor laser device. A package of semiconductor laser devices 23a to 23c comprises three lead terminals, and an electrical connection to two lead terminals, which are electrically insulated from a metallic base, is established. If a light collection point P is positioned in the midway of the detection distance range, the shifting quantity of the laser beams is minimized over substantially the entire area so that the amount of lights can be suppressed.
