An interdental treatment device, such as a toothbrush, includes a handle configured to accommodate an electric power source, a head carrying an interdental treatment tool, and a neck between the handle and the head. The head or neck includes a mechanical motorized vibratory device, including a drive which causes the head to vibrate. Electrical connections are operably connected to the mechanical vibratory device and the electric power source to power the mechanical vibratory device via the electrical connections. In various embodiments, a switch may be operably connected to at least one of the electrical connections to interrupt power from the power source to the mechanical motorized vibratory device. In various embodiments, a vibration-damping structure dampens vibration transmission from the head to the handle.

The head or neck includes a mechanical motorized vibratory device, including a drive which causes the head to vibrate. Electrical connections are operably connected to the mechanical vibratory device and the electric power source to power the mechanical vibratory device via the electrical connections. At least parts of the electrical connections are formed by tracks of an electrically conductive plastic material. In various embodiments, a vibration-damping structure dampens vibration transmission from the head to the handle.

In a projection system for projecting a video picture composed of picture points on a screen with at least one light source which emits a light bundle and can be varied in intensity and with a deflecting device which deflects the light bundle to illuminate the picture points on the screen, a transformation optical system having at least two stages is arranged between the deflecting device and the screen and is corrected according to the tangent condition so as to be free of distortion. The transformation optical system has at least two optical stages. The first optical stage produces an intermediate image plane which is imaged on the screen by means of the subsequent optical stage (s).

The invention relates to a component 1 for a hi-fi system. This component has plug connection contacts P.sub.1 to P.sub.4, the plug connection contact P.sub.1 being arranged on the top 10, the plug connection contact P.sub.2 on the right-hand side 11, the plug connection contact P.sub.3 on the bottom 12, and the plug connection contact P.sub.4 on the left-hand side 13. These plug connection contacts are connected, on the inside, with each other and at least with the LF-signal source of the component. Wiring is no longer necessary, since the individual components can be connected with each other via the plug connection contacts both in the event that they are arranged alongside of each other and in the event that they are arranged one above the other.
