Title: METHOD OF FORMING AN ELONGATED BODY WITH AN EMBEDDED CHANNEL
Abstract:
A method of forming an elongated body with an embedded channel extending longitudinally beneath a surface along a length of the elongated body, comprising forming the elongated body with an opened channel recessed into the elongated body; the opened channel having an inner and outer portion proximal and distal to and from a channel bottom respectively of the opened channel. The method further comprises placing an elongated cover over the opened channel, and having a base and two slope surfaces extending from the base toward an apex opposite the base to cover the inner portion of the opened channel with the base, and to form two grooves each having a profile defined by a corresponding slope surface of the elongated cover and a corresponding outer portion of the opened channel forming the groove. The method further comprises filling the two grooves to join the elongated cover to the elongated body.
