PROBLEM TO BE SOLVED: To provide an ice thawing device with small power consumption and no danger of fire. SOLUTION: For water pipes, the device thaws away ice on water pipes with a tip tool 6 with a built-in ultrasonic wave vibrator 4 fitted on it for directly transmitting ultrasonic wave acceleration and vibration energies to the ices. For road surfaces 17, the device is a disc-shaped ultrasonic wave generator including an ultrasonic wave vibrator 11 etc., buried in the center of road surface and transmitting these ultrasonic wave acceleration and vibration energies to thaw ices and snows piled up on the frozen road surface. An ultrasonic wave mat 20 used for a passage surface works in a similar way. In the case of cars, an ultrasonic wave generator having its small-disc ultrasonic wave vibrator 40 protected by a soft resin material around can be stuck on the outer surface of front window glass at a position of a lower elastic rubber frame 35 supporting and fixing the front window glass to thaw or disperse, prevent the attachment of or remove (including the cleaning of) ices, rain or snow to or from the window glass surface by means of ultrasonic wave acceleration and vibration energies. The device can also be useful to prevent the damage of wipers and secure the drivers' field of vision. COPYRIGHT: (C)2006,JPO&NCIPI
