The first electrode section (7a) and the second electrode section (7b) are formed such that the outer portion connected to the upper portion of the heating section (6) is thinner than the inner portion connected to the lower portion of the heating section (6). The heating section (6) and the first electrode section (7a) are interconnected by an R-shaped first connecting portion (21). The inner circumferential sloping surface of the heating section (6) and the second electrode section (7b) are interconnected by an R-shaped second connecting portion (22). The first and second connecting portions (21)(22) are formed such that R becomes larger from the upper end to the lower end, where the upper portion is thin and the lower portion is thick. The thickness of an intermediate portion (6b) is smaller than the thicknesses of the first and second connecting portions (21)(22).

The present invention sufficiently heats a repairing material while preventing change in quality of a base material provided with the repairing material so as to securely bond the repairing material to a repair target portion. The repair method of the present invention, in order to repair a repair target portion 14 existing in an outer panel 1, includes: a repairing material disposing step of disposing a repairing patch 21 including a resistance heating element 23 and a carbon fiber reinforced resin, and an adhesive 22A including a thermosetting resin before being hardened for bonding the repairing patch 21 on the repair target portion 14; and a heating-hardening step of heating and hardening the thermosetting resin of the adhesive 22A by causing the resistance heating element 23 to generate heat through supply of electricity thereto.

The invention relates to a device for curing inner linings of pipelines introduced into them in the form of lining tubes impregnated with a resin. The device includes metal three-piece monolithic body (52) both of the two extreme cylindrical portions (53 and 54) of which have a diameter (1) larger than the diameter (1) of its middle cylindrical portion (56), whereas all components of the body are connected with each other detachably, and both of the two extreme portions (53 and 54) are provided on their cylindrical circumferences with a dozen or so longitudinal ribs (65) each distributed symmetrically on them along the circumferences and having an identical thickness (U) and height (V), and moreover, the ribs are provided with circumferential slit-shaped recesses (66) situated opposite from each other and oriented perpendicularly to horizontal axis (67) of the device forming thus profiles functioning as radiators (68) composed of individual segments (69) separated from each other with elongated recesses with an dilation angle () and with crosswise circumferential slit-shaped recesses (66), whereas the middle portion (56) of the body on its circumference with diameter (1) has also a dozen or so flat facets-chords (74) evenly distributed along the circumference and separated from each other with radially oriented slit-shaped recesses (75) ending on solid core (64) of this portion of the body (52) in which power leads (80) are guided supplying electric current to LEDs (79) and to the front camera unit (40), said recesses forming profiled figures functioning as radiators (76) flat facets (74) of which are connected detachably with plastic strip-shaped plates (78) with LEDs (79) installed in them, and moreover, both of the two extreme portions (53 and 54) of the body (52) are provided with round axial holes (61) ending with bevelled chamfers (62) forming annular slots (63) situated between them and the solid core (64) of the middle portion (56) of the body, whereas the axial holes (61) are coaxial with holes (59) of both of the two profiled shields (58) connected detachably with outer faces of both of the two extreme portions (53 and 54) of the body (52) of the device.

A method for fabricating assemblies that includes providing a first component that further includes silicon carbide and that has an upper portion and a tapered lower portion; providing a second component that further includes silicon carbide and that has an upper portion that is adapted to receive the tapered lower portion of the first component; providing a predetermined amount of multiphase AlSi braze foil; grinding the AlSi braze foil into a powder; mixing a predetermined amount of braze paste binder with the AlSi powder to form a slurry; uniformly applying the slurry to the tapered lower portion of the first component; uniformly applying the slurry to the upper portion of the second component and inserting the tapered lower portion of the first component into the upper portion of the second component; and heating the applied slurry to a temperature of 725 C. to 1450 C. for a predetermined period of time.
