A frame structure for a vehicle body which has a first frame member having a web portion and flanges, which stand from opposite ends of the web portion, a second frame member having a web portion and flanges which stands from opposite ends of the web portion, and a reinforcement having a web portion and flanges, which stands from opposite ends of the web portion. The reinforcement is inserted within the first frame member, and the web portion of the reinforcement is in contact with the web portion of the first frame member. The flanges of the reinforcement are in contact with the flanges of the first frame member, and the edges of the flanges of the second frame member strike against the edges of the flanges of the reinforcement. The flanges of the reinforcement have upper portions and lower portions. The edges of the flanges of the second frame member strike against the edges of the upper portions, and the lower portions of the reinforcement are welded to the flanges of the first frame member. Thus, if the strength required for the frame structure is constant, the thickness of the outer and inner channels can be reduced because of the disposition of the reinforcement.

When the mode is switched to a motion detection mode, using a changeover switch, the mode is switched to the motion detection mode by pressing the changeover switch. In this mode, motion detection is performed by moving a hand in an area to be operated. When the mode is switched from the motion detection mode to a normal mode, the hand is moved away from the area to be operated, or the changeover switch is again pressed. Moreover, when the hand is distant from a capacitive sensor, it is determined that a motion input operation is being performed. When the hand is close to the capacitive sensor, it is determined that no motion input operation is being performed, and thus the motion detection mode is changed.

A sound control system includes a plurality of electronic devices connected to a communication network, each of the electronic devices being capable of independently producing sound from connected speakers, and a sound control device transmitting control signals for controlling the electronic devices and audio signals to the electronic devices via the communication network. Each electronic device includes receiving means for receiving the control signals and the audio signals via the communication network, and selecting means for switching from other external signals to the audio signals in response to the control signals in order to drive the speakers by only the audio signals output to the speakers.

An adjustable joint unit includes a ball stud having a stud portion that is provided at one end thereof with a ball head portion, a bearing seat to contain the ball head portion, and a generally plate-shaped arm having a generally cylindrical socket portion. Also, an aperture portion permits the stud portion to be inserted therethrough. Additionally, the joint unit includes a mounting opening portion located at the base end of the socket portion, and a closing member which is adapted to be attached in such a manner as to close off the mounting opening portion at the base end of the socket portion and apply a given preliminary load to the ball head portion of the ball stud.
