`
`Dental Ultrasonic Washer
`
`2. Claim
`
`A dental ultrasonic washer comprising:
`
`an oral attachment part including an ultrasonic vibrator having a
`
`horseshoe shape, and a pliable insulating member
`
`for covering the
`
`ultrasonic vibrator; and
`
`a power supply portion for supplying an electric power to the
`
`ultrasonic vibrator, wherein
`
`the power supply portion applies a voltage to the ultrasonic
`
`vibrator in the oral attachment part attached to a teeth part in a buccal
`
`cavity filled with a
`
`liquid to thereby apply a vibration from the
`
`ultrasonic vibrator to the teeth through the liquid.

`
`DETAILED DESCRIPTION
`
`
`
`[A detailed explanation of the device]
`[0001]
`[Industrial Application]
`This device is related with the device from which waterdrop, fog, frost, ice, etc. the mirror
`surface of the mirror for vehicles was frozen are removed.
`[0002]
`[Description of the Prior Art]
`If a mirror is [ being waterdrop, being frost, and ] frozen, in order to bar the field of view of a
`mirror, supersonic vibration is given to a mirror, the waterdrop stripper of the mirror which
`atomizes the waterdrop adhering to the surface, etc. is already carried out [ whether it is also
`practical use or ], and the thing JP,H2-231249,A and given in JP,H3~104755,A etc. are known.
`Drawing ~Cishows the waterdrop stripper shown in the above-mentioned gazette. As for the
`piezoelectric transducer 11 which will generate supersonic vibration in disc shape if voltage is
`applied, the polar zone 11a and 11a is allocated in the upper and lower ends. The vibrator 11 is
`sandwiched by the flexible printed circuit board 12. It had the metallic thin plate 13, this metallic
`thin plate 13 consisted of rolled copper foil etc., and had the same area as the polar zone 11a,
`and the flexible printed circuit board 12 has pasted it up so that the whole surface of the polar
`zone 11a may be covered.
`[0003]
`[Problem(s) to be Solved by the Device]
`However, in such a conventional structure metallic thin plates, such as copper foil, Since the
`biggest stress arises in the adhesion peripheral part of a vibrator and a metallic thin plate when
`adhesive strength is dramatically weak compared with a flexible printed circuit board etc. and a
`vibrator is vibrated to a diameter direction, If supersonic vibration is given to a mirror in order to
`remove the waterdrop adhering to the mirror surface, etc., Since it was easy to generate
`exfoliation from the jointing periphery of a metallic thin plate and the electrode of a vibrator and
`area of an electrode and area of the metallic thin plate were further made the same, when a core
`gap slight at the time of adhesion arose, there was a problem in endurance -- the adhesive
`strength of a peripheral part serves as non-**, and it will be in the state of being easier to
`generate exfoliation.
`[0004]
`
`What is necessary is just to raise the adhesive strength to the electrode of a metallic thin plate,
`in order to prevent exfoliation. For this reason, although the surface of a metallic thin plate is
`usually polished with a sandpaper, unevenness is given to the surface and the method of
`changing into a rough state is taken, when polishing the metallic-thin-plate surface with a
`sandpaper, a crack takes lessons also from a flexible printed circuit board, and the problem that
`reliability falls on the contrary produces.
`Then, this design is made in order to improve the above-mentioned problem, it raises the
`adhesive strength of a piezoelectric transducer and a flexible printed circuit board, and aims at
`providing the waterdrop stripper which can raise the endurance to supersonic vibration.

`
`[Means for Solving the Problem]
`In a device from which this design drives a piezoelectric transducer and waterdrop on the
`surface of a mirror, etc. are removed in order to attain the above-mentioned purpose, It has a
`piezoelectric transducer and a flexible printed circuit board which has copper foil, and is
`characterized by area of a copper foil part electrically connected with polar zone of a
`piezoelectric transducer being smaller than area of a piezoelectric transducer, and, as for copper
`foil, it is desirable that it is electrolytic copper foil.
`[0006]
`[Function]
`If copper foil of a flexible printed circuit board is pasted up on the electrode of a piezoelectric
`transducer with adhesives, Compared with an electrode, a copper foil periphery is covered, a
`flexible printed circuit board with strong adhesive strength comes to be directly fixed to an
`electrode, and the adhesive strength of a part with a small area of copper foil and adhesives of
`the peripheral part which becomes the largest [ stress ] at the time of vibration improves.
`[0007]
`[Example]
`Next, one working example of this device is concretely described based on Drawings. Drawing 1
`is the development view and the sectional view in which drawing 2 shows the structure of an
`important section showing one working example of the waterdrop stripper of this design in part. If
`1 applies voltage, the electrodes 1a and 1a which consist of silver or nickel are allocated in the
`top-and-bottom-ends side of the piezoelectric transducer and the piezoelectric transducer 1
`which generate supersonic vibration. The flexible printed circuit board 2 which consists of
`polyimide has the copper foil 3 electrically connected with the electrode 1a of a vibrator. As for
`the copper foil 3, it is desirable to use electrolytic copper foil as a material, and it makes area of
`the copper foil 3 smaller than the area of the electrode 1a. Therefore, if it is made not much
`small too much, in order to affect the electrical property of the vibrator 1, when referred to as
`D: 50, it is preferred, although the diameter d of the copper foil 3 is small compared with the
`diameter D of the electrode 1a to set it as the value of d: 25 thru/or 45 within the limits. The
`
`flexible printed circuit board 2 is being fixed to the vibrator 1 with the epoxy resin 4. Since the
`area of the copper foil 3 is smaller than the area of the electrode 1a, as shown in drawing 2, the
`peripheral part of the vibrator 1 has bonded structure of not copper foil but the electrode 1a,
`and the flexible printed circuit board 2.
`[0008]
`[Effect of the Device]
`As mentioned above, as the waterdrop stripper of this design has been explained, by having made
`smaller than the area of the polar zone area of copper foil of the flexible printed circuit board
`electrically connected with the polar zone of a piezoelectric transducer, the adhesive strength
`between a flexible printed circuit board and a vibrator becomes large, and vibration durability
`improves. There is also no fear of damaging a flexible printed circuit board, since adhesive
`strength is raised without polishing copper foil with a sandpaper, Even if the speed of adhesion
`also increases and some core gap arises at the time of adhesion with a vibrator and a flexible
`printed circuit board, adhesive strength and an electrical property are hardly influenced, but the
`reliability in a bonding process improves.
