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.

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 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:
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.

An actuator and actuator control system is provided for use with a mirror-like surface and is used to remove foreign substances from the mirror-like surface. The actuator may be a piezoelectric device and the control system operates the device in a predetermined vibratory manner to remove the foreign substance.
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.
