Filed: 1987-03-04
Abstract: PURPOSE:To enable both the automatic and manual setting of the sound volume of a sound source corresponding to a noise level, by switching and using two sound volume control means. CONSTITUTION:A CPU3 switches a mode to two kinds of emitting sound volume control modes of a speaker 5 corresponding to the operating state of a switch 1a. A first mode of them is a sound volume automatic control mode which controls the emitted sound volume of the speaker 5 corresponding to the noise level of the periphery of a device, and a second mode is a sound volume fixed mode which controls the emitted sound volume of the speaker 5 at a prescribed value. In such a way, the sound volume control mode of the speaker 5 can be switched to two kinds of modes by setting the switch 1a. Therefore, a data representing whether the mode is the sound volume fixed mode or the sound volume automatic control mode is stored in a mode storage part 2a corresponding to the operating state of the switch 1a. In such a way, it is possible to perform both the automatic setting and manual setting of the sound volume of the sound source corresponding to the noise level.

IPC: B23K26/21
Filed: 1981-03-31
Abstract: PURPOSE:To perform good welding free from defects such as lack of penetration by subjecting the butt parts of metallic materials to seal bead welding by irradiating an energy beam to the peripheries including said butt parts then to regular welding. CONSTITUTION:A focus 13 of a laser beam 12 is positioned slightly upper than the surfaces of steel plates 11 with respect to the groove spacing butted with metallic materials such as cold rolled steel plates, and the beam 12 is irradiated to the peripheries including the butt parts of the plates 11, whereby seal beads 14 are formed to seal the groove spacing. Thence, the beam 12 is irradiated again to the butt parts, whereby regular welding is accomplished.
