    Abstract: A method for forming a thermoelement for a thermoelectric cooler is provided. In one embodiment a first substrate having a plurality of pointed tips separated by valleys wherein the substrate is covered by a metallic layer, portions of the metallic layer is covered by an insulator, and other portions of the metallic layer are exposed is formed. The other portions of the metallic layer that are exposed are covered with a thermoelectric material overcoat. A second substrate of thermoelectric material is then fused to the pointed tip side of the first substrate by, for example, heating the back of the first substrate to melt the thermoelectric material overcoat or by passing current through the pointed tips to induce Joule heating and thereby melt the thermoelectric material overcoat.

    Abstract: The method comprises introducing a tip (40) of a solid phase welding tool (126) between adjacent surfaces of a crack (132) formed in an aircraft skin. The tool (126) is then operated to produce a friction stir weld so as to weld the adjacent surfaces together and thereby repair the crack (132). Apparatus for performing the method comprises a base (50) having carriage (55) thereon, the arm (76) being pivotally mounted on the carriage (55) and supporting the friction stir welding tool (126). The position of an arm (76) can be adjusted by a screw (94) which drives the rotating tip (40) of friction stir welding tool (126) into the crack (132) to be repaired. The carriage (55) is then moved along the base (50) to draw the tip (40) along the crack. The apparatus is portable and is particularly useful for repairing a cracked skin on an aircraft.

    Abstract: A rotary tool 140 is relatively moved against members 30, 30 to be welded so as to perform friction stir welding of said members, while blades 145 mounted on the rotary tool 140 and a rotary brush 220 are used to cut the welded portion, and swarfs on the cut surface are removed through a suction opening 225, before medium liquid is supplied on said cut surface through a supply opening 240. Next, an inspection roller 250 is rotated on the surface of the welded portion for inspection. A probe 251 is provided within the roller 250. Upon detecting defect, paint is applied to the position of defect by a marking device 270. Thereafter, based on said marking, the joint portion is cut and repaired by welding.

    Abstract: An apparatus for processing printed circuit boards including a system for measuring and controlling solder wave height generally comprises conveyor system for transporting printed circuit board through a number of processing stations. The system for measuring and controlling the wave height of solder includes a sensor which is mounted in close proximity to the interface defined between the surface of the solder wave and the bottom surface of the printed circuit board. The sensor is coupled to a micro-controller and the micro-controller is coupled to a pump motor. The pump motor is coupled to a solder bath which generates the solder wave and is controlled to operate at a predetermined speed to maintain a predetermined solder wave height during the process of wave soldering printed circuit boards. The sensor provides a number voltages to the micro-controller representing the distance between the sensor and the top surface of the solder wave. The voltages are converted into a number of values. The micro-controller includes a comparator which receives the values and compares the values to a predetermined set point to determine whether the solder wave height is too high or to low and the micro-controller further determines whether to respectively decreased or increased the speed of the pump motor.
