Claims
- 1. A member coupling device for mounting thereon a member under treatment with a chemical, comprising:
a base having a tapered hole formed therein, said tapered hole including a tapered hole portion which diverges toward an opening; a tapered implant inserted into said tapered hole from an enlarged side of said tapered hole portion and fitted in said tapered hole, said tapered implant having an outer surface in the form of a circular truncated cone, said tapered implant comprised of a tapered portion in contact with said tapered hole portion, a projecting portion formed at an end coupled to an enlarged end of said tapered portion, protruding from said tapered portion, and in contact with said member under treatment around said tapered hole portion, and a first thread formed on said tapered portion; and a fastening member formed with a second thread for screw coupling with said first thread of said implant, wherein said member under treatment is placed in contact with said base with said implant being fitted in said tapered hole, and said member is mounted to said member coupling device by engaging said first thread of said implant with said second thread in a screw coupling configuration.
- 2. A member coupling device according to claim 1, wherein:
said first thread is a female thread formed within said tapered portion in a direction of a center axis of said tapered portion; said fastening member is a bolt formed with a male thread as said second thread; said fastening member is inserted into said female thread of said implant through a hole formed through said member under treatment, with said male thread of said fastening member being in screw coupling with said female thread of said implant, to mount said member under treatment on said member coupling device.
- 3. A member coupling device according to claim 1, wherein:
said tapered implant comprises a bolt on an end face on either an enlarged side or a reduced side of said tapered portion, said bolt being formed with a male thread as said first thread; said fastening member is a nut having a female thread formed on an inner face thereof as said second thread; and said bolt is inserted through a hole formed through said member under treatment, with said male thread of said bolt being in screw coupling with said female thread of said nut, to mount said member under treatment on said member coupling device.
- 4. A member coupling device according to claim 1, further comprising a masking member placed in contact with said member under treatment, wherein said member under treatment and said masking member are mounted on said member coupling device by engaging said first thread of said implant with said second thread in a screw coupling configuration.
- 5. A member coupling device according to claim 1, wherein:
said base is formed of a resin material; and said implant is formed of a material selected from a group consisting of titanium, hard plastic and stainless steel.
- 6. A treatment apparatus for treating a member with a chemical, comprising:
a member coupling device placed in said treatment apparatus for mounting said member thereon; a tapered hole formed in said member coupling device and having a tapered hole portion including a diverging opening; a tapered implant inserted into said tapered hole from an enlarged side of said tapered hole portion and fitted in said tapered hole, said tapered implant having an outer surface in the form of a circular truncated cone, said tapered implant comprised of a tapered portion in contact with said tapered hole portion, a projecting portion formed at an end coupled to an enlarged end of said tapered portion, protruding from said tapered portion, and in contact with said member under treatment around said tapered hole portion, and a first thread formed on said tapered portion; and a fastening member formed with a second thread for screw coupling with said first thread of said implant, wherein said member under treatment is placed in contact with said member coupling device with said implant being fitted in said tapered hole, and said member under treatment is mounted to said member coupling device by engaging said first thread of said implant with said second thread in a screw coupling configuration.
- 7. A treatment apparatus according to claim 6, wherein:
said first thread is a female thread formed within said tapered portion in a direction of a center axis of said tapered portion; said fastening member is a bolt formed with a male thread as said second thread; said fastening member is inserted into said female thread of said implant through a hole formed through said member under treatment, with said male thread of said fastening member being in screw coupling with said female thread of said implant, to mount said member under treatment on said member coupling device.
- 8. A treatment apparatus according to claim 6, wherein:
said tapered implant comprises a bolt on an end face on either an enlarged side or a reduced side of said tapered portion, said bolt being formed with a male thread as said first thread; said fastening member is a nut having a female thread formed on an inner face thereof as said second thread; and said bolt is inserted through a hole formed through said member under treatment, with said male thread of said bolt being in screw coupling with said female thread of said nut, to mount said member under treatment on said member coupling device.
- 9. A treatment apparatus according to claim 6, wherein said member coupling device further comprises a masking member placed in contact with said member under treatment, wherein said member under treatment and said masking member are mounted on said member coupling device by engaging said first thread of said implant with said second thread in a screw coupling configuration.
