Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
53 words
Laser light irradiation apparatus comprising a penetrating member and at least one transmitting member through which laser light goes so as to be fed into said penetrating member, said apparatus being characterized by; said penetrating member which contains laser light scattering particles and which is fabricated from a laser light penetrating synthetic material.
Claim 2
Dependent Claim
40 words
Laser light irradiation apparatus according to claim 1, wherein said laser light transmitting member is an optical fiber and the fore end portion of a core of said optical fiber is buried in said synthetic material of said penetrating member.
Claim 3
Dependent Claim
26 words
Laser light irradiation apparatus according to claim 2, wherein a laser light scattering layer is formed on the surface of the buried part of said core.
Claim 4
Dependent Claim
31 words
Laser light irradiation apparatus according to claim 3, wherein said laser light scattering layer is fabricated from heat resistant ceramic particles partly melting and partly remaining to be in a particle-state.
Claim 5
Dependent Claim
39 words
Laser light irradiation apparatus according to claim 1, wherein said penetrating member is supported to be surrounded by a holder on its inner surface and a laser light reflecting layer covers at least a part of said inner surface.
Claim 6
Dependent Claim
17 words
Laser light irradiation apparatus according to claim 5, wherein said reflecting layer is a gold plated layer.
Claim 7
Dependent Claim
104 words
Laser right irradiation apparatus comprising a penetrating member, at least one transmitting member through which laser light goes so as to be fed into said penetrating member and a lead wire for detecting a temperature, said apparatus being characterized by; said penetrating member which contains laser light scattering particles and which is fabricated from a laser light penetrating synthetic material; and said lead wire which is inserted through said penetrating member so as to be projected from the external surface of the fore end portion of said penetrating member and inserting part of which is buried in said synthetic material of said penetrating member.
Claim 8
Dependent Claim
30 words
Laser right irradiation apparatus according to claim 7, wherein at least said inserting part and the projecting part of said lead wire are coated by a laser light reflecting material.
Claim 9
Dependent Claim
57 words
Laser right irradiation apparatus according to claim 1 or 7, wherein a surface layer is formed on the surface of said laser light penetrating member and said surface layer contains laser light absorbing particles, light scattering particles having a larger refractive index than that of said penetrating member and a laser light penetrating material as a binder.
Claim 10
Dependent Claim
29 words
Laser right irradiation apparatus according to any claim of claims 1, 7 and 9, wherein a rough surface is formed on the surface of said laser light penetrating member.
