Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
143 words
An electric wire shielded with an electromagnetic wave shield tape comprising: an electric wire; a strip-shaped conductive member and a strip-shaped insulative member, said conductive member being fixed to said insulative member so as to partially overlap said insulative member in a widthwise direction, wherein said insulative member is offset from said conductive member to define an offset portion on said insulative member, and wherein an adhesive material is applied at least to said offset portion; wherein said electromagnetic shield tape being wound helically on an outer surface of said electric wire so that said adhesive material applied to said offset portion adheres to said electric wire during a first winding turn of said tape being wound on said electric wire and so that a successive winding turn of said shield tape partially overlaps a winding turn of said shield tape just wound.
Claim 2
Dependent Claim
143 words
An electric wire shielded with an electromagnetic wave shield tape comprising: an electric wire; a strip-shaped conductive member and a strip-shaped insulative member, said conductive member being fixed to said insulative member so as to partially overlap said insulative member in a widthwise direction, wherein said insulative member is offset from said conductive member to define an offset portion on said insulative member, and wherein an adhesive material is applied at least to said offset portion; wherein said electromagnetic shield tape being wound helically on an outer surface of said electric wire so that said adhesive material applied to said offset portion adheres to said electric wire during a first winding turn of said tape being wound on said electric wire and so that a successive winding turn of said shield tape partially overlaps a winding turn of said shield tape just wound.
Claim 3
Independent Claim
144 words
A method of shielding an electric wire with an electromagnetic wave shield structure having a strip-shaped conductive member and a strip-shaped insulative member, comprising the steps of: providing an electric wire; fixing said insulative member to said conductive member so that said insulative member partially overlaps said conductive member in the widthwise direction to thereby form an electromagnetic wave shield tape; providing an adhesive material on a surface of an offset portion where said insulative member is offset from said conductive member; and winding helically said electromagnetic shield tape on an outer surface of said electric wire so that said adhesive material applied to said offset portion adheres to said electric wire during a first turn of winding said tape on said electric wire and a successive winding turn of said shield tape partially overlaps a winding turn of said shield tape just wound.
Claim 4
Independent Claim
144 words
A method of shielding an electric wire with an electromagnetic wave shield structure having a strip-shaped conductive member and a strip-shaped insulative member, comprising the steps of: providing an electric wire; fixing said insulative member to said conductive member so that said insulative member partially overlaps said conductive member in the widthwise direction to thereby form an electromagnetic wave shield tape; providing an adhesive material on a surface of an offset portion where said insulative member is offset from said conductive member; and winding helically said electromagnetic shield tape on an outer surface of said electric wire so that said adhesive material applied to said offset portion adheres to said electric wire during a first turn of winding said tape on said electric wire and a successive winding turn of said shield tape partially overlaps a winding turn of said shield tape just wound.
Claim 5
Independent Claim
169 words
A method for shielding an electric wire from a noisy electromagnetic wave or an undesirable electromagnetic energy induction or radiation, comprising the steps of: providing an electric wire, a strip-shaped insulative member and a strip-shaped conductive member; fixing said insulative member to said conductive member so that said insulative member partially overlaps said conductive member in the widthwise direction to thereby form an electromagnetic wave shield tape; providing an adhesive material on a surface of an offset portion of said insulative member where said insulative member is offset from said conductive member and not overlapped thereby when said insulative member is fixed to said conductive member; and winding helically said electromagnetic wave shield tape on an outer surface of said electric wire so that said adhesive material applied to said offset portion adheres to said electric wire during a first turn of winding said tape on said electric wire and each successive winding turn of said shield tape partially overlaps a winding turn of said shield tape just wound.
Claim 6
Independent Claim
169 words
