Abstract: The present invention provides a functional food that utilizes health-promoting effects of charcoal, is readily ingested, has no adverse side effect, and has an effect of improving and repressing obesity. The functional food includes a charcoal composition having at least one of a bamboo charcoal, a Bincho charcoal, an activated bamboo charcoal and an activated Bincho charcoal, and both of the activated bamboo charcoal and the activated Bincho charcoal have a bulk density of 0.3 to 0.6 g/ml, an average particle size of 10 ?m or smaller, a BET specific surface area of 1000 to 1200 m2/g, and an iodine adsorption amount of 1000 to 1300 mg/g.

Abstract: A displacement detecting switch device is assembled with ultrasonic welding techniques, so that easiness of assembling work for it is further increased. The device comprises a switch body including a cover body and a base plate; an operation lever disposed pivotably outside of the switching body; and a movable plate disposed inside of the switch body and linked with the operation lever. There are disposed a first joint portion and a second joint portion formed by ultrasonic welding between the cover body and the base plate and between the operation lever and the movable plate, respectively.
