摘要:
A power supply device adapted to supply power to a pair of electrodes formed on opposite end surfaces of an ultrasonic vibrator. The device has a circuit layer arranged on a flexible base. The circuit layer has a pair of supply electrodes arranged at its one longitudinal end and a pair of end connections arranged at the other longitudinal end. A pair of conductive layers electrically connect the supply electrodes and the end connections, respectively. Each supply electrode has an inner surface of substantially the same shape as the end surface of the ultrasonic vibrator, the inner surface being joined electrically and mechanically with the electrode of the ultrasonic vibrator. The flexible base has an electrode base covering an entire outer surface of each of the supply electrodes, and a circuit base holding the conductive layers. A shield layer may be disposed on the flexible base in order to screen electromagnetic radiation from the circuit layer.

The cleaning apparatus for removing foreign substances includes a spacer which is interconnected between a generally planar member and a vibrator, wherein the spacer provides a space for separating the generally planar member from the vibrator. The spacer allows the generally planar member to bend easily. Thus, a large amplitude of vibration can be obtained on the whole of the generally planar member.

A device for removing water droplets comprises a plate-like member disposed vibratably, a vibrator bonded to the rear face of the plate-like member and oscillation means for vibrating the vibrator at a predetermined frequency, wherein the thickness and/or the diameter of the vibrator is optimized in relation with the thickness thereof, or the longitudinal, lateral width or thickness of the plate-like member. The water droplets on the plate-like member, e.g., automobile mirror can be removed effectively and uniformly with no worry for the destruction of the vibrator. The oscillation means may, advantageously, be adapted to cause bending vibrations to the vibrator by lateral effect.

The vehicle mirror of the present invention is made such that a supporting member is arranged with a predetermined spacing in respect to the rear mirror member of an anti-halation mirror member having the anti-halation device such as liquid crystal or electrochromic element or the like between the front transparent member and the rear mirror member getting a reflection as the mirror, the piezo-electric vibrator generating vibration is fixed to the supporting member, a spacing between the rear mirror member and the supporting member is held by the spacer member and then the vibration of the piezo-electric vibrator is tansmitted to the front transparent member. The front transparent member is exposed from the opening of the holder and at the same time the circumferential edge of the anti-halation mirror member is held by the holding part. With such an arrangement above, a function of anti-halation and another function of removing water droplets can be provided.
摘要:
An arrangement is provided for removing foreign substances from a mirror. A vibrator for vibrating the mirror includes a vibration controlling unit for supplying power to the vibrator. As the vibration controlling unit is located close to the vibrator, the length of the conductive wire which transmits the power can be minimized so as to reduce radio noise. The heat generated by the vibration control unit can be radiated sufficiently through a metallic case member and the vibration controlling unit can be disposed in the closed, small space between the mirror and the housing. Therefore, the size of the housing can be reduced so as to minimize the space which surrounds the vibration control unit. Further, the vibration control unit can be protected from contamination due to the closed case member.

A cleaning arrangement for an outside rear view mirror of an automobile cleans and removes frost, ice and water droplets from the mirror. A heating element is provided to quickly heat and melt frost and ice into water droplets. A piezoelectric element is provided to vibrate the mirror to cause water droplets to be atomized and removed from the mirror.
摘要:
A self-cleaning plate shaped device for use in an automotive rear view mirror. The device preferably includes a mirror and a vibrator disposed on the mirror for propagating oscillations in the mirror substantially entirely parallel to the plane of the mirror. The vibrations remove foreign substances from the mirror. The mirror also includes a heater disposed on the back of the mirror for distributing heat substantially entirely throughout the mirror. When the mirror is heated by the heater, a moisture blur or the like are evaporated quickly and removed from the reflecting surface of the mirror. Further, frost, ice and the like is melted into water drops, and removed from the reflecting surface of the mirror due to the vibration of the mirror by the vibrator.
摘要:
An outside mirror of a vehicle has an ultrasonic vibrator attached to its rear side for removing water and the like from the front side of the mirror. The mirror is attached to a frame by means of a supporting member extending around an outer peripheral edge of the mirror. The supporting portion is formed of a material having less acoustic impedance than the mirror. The vibrator has electrode connectors connected to wires from a control device by being mechanically clamped to those wires.
