Abstract
Abstract A patient supporting table top for X-ray inspection apparatus which includes a platelike core member formed by mixing thermosetting resin with a great number of hollow carbon microspheres reinforced with carbon fibers and press-heating these materials. A covering member is bonded to each side of the core member by using an adhesive agent such as epoxy resin. The covering member is formed by mixing resin material with carbon fiber network and press-heating these materials.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
91 words
A patient supporting table top for mechanical examination and therapy apparatus comprising a plate-like core member and covering layer members bonded to said core member, said core member being sandwiched between said covering layer members; the improvement wherein said core member includes a great number of independent hollow carbon microspheres as the principal material thereof, said microspheres being mixed with a thermosetting resin to form said core member, each said covering layer member including a carbon film network having a resin material mixed therewith to form carbon fibre reinforced plastic members.
Claim 2
Dependent Claim
91 words
A patient supporting table top for mechanical examination and therapy apparatus comprising a plate-like core member and covering layer members bonded to said core member, said core member being sandwiched between said covering layer members; the improvement wherein said core member includes a great number of independent hollow carbon microspheres as the principal material thereof, said microspheres being mixed with a thermosetting resin to form said core member, each said covering layer member including a carbon film network having a resin material mixed therewith to form carbon fibre reinforced plastic members.
Claim 3
Dependent Claim
21 words
A patient supporting table top according to claim 1, wherein said core member further includes fibrous material for reinforcing said microspheres.
Claim 4
Dependent Claim
21 words
A patient supporting table top according to claim 2, wherein said fibrous material of said core member is made of carbon.
Claim 5
Dependent Claim
30 words
A patient supporting table top according to claim 3, wherein an epoxy resin adhesive is used as an adhesive agent for bonding said core member with said covering layer members.
Claim 6
Independent Claim
83 words
A method of manufacturing a patient supporting table top for medical examination and therapy apparatus, comprising the steps of forming a plate-like core member by mixing a thermosetting resin with a large number of independent hollow carbon microspheres, and then press-heating said mixed materials; forming covering layer members by knitting carbon fibres and mixing resin materials therewith, and then press-heating said mixed covering layer member materials; and bonding said covering layer members to each side of the core member using an adhesive agent.
Claim 7
Independent Claim
