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.

An outside mirror for a vehicle has a ultrasonic vibrator and a heating member in order to quickly remove the foreign substances from the entire surface of a mirror member. The ultrasonic vibrator is rigidly fixed to a supporting member. The supporting member is rigidly fixed to outer edges of the mirror member. A space is provided between the mirror member and the supporting member. The heating member is installed in the space. The ultrasonic vibrator atomizes water drops on the mirror member. The heating member melts ice, frost or other foreign substances on the mirror member. The ice, frost or the other foreign substances which are melted by the heating member are removed by the ultrasonic vibrator.

An outside mirror for a vehicle includes a generally planar member, a supporting member rigidly secured to the generally planar member and a vibrator rigidly secured to the supporting member. A space is provided between the generally planar member and the supporting member. The supporting member and the generally planar member have a similar coefficient of linear expansion in order to reduce the stress applied to the generally planar member and lessen the distortion of the planar member.

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.

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.

A mirror device for an automobile includes a mirror member. A seal member is vibratably held to an outer circumference portion of the mirror member. A holder member is held to the seal member, is positiond at a reverse side of the mirror member and is vibratably held to the mirror member through the seal member. A vibrator is served for vibrating the mirror 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.
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.
