摘要： An apparatus for generating cold and hot for application selectively by contact on an object having a paint or coating whose color changes in response to cold and hot temperatures. The apparatus is easy to hold and handle with one hand while holding an object for application, e.g., a doll or toy car, in the other hand. The apparatus includes a battery powered thermoelectric device having a cold sink shaped to form a cold applicator for cooling the paint sufficiently to change its color, and a heat sink shaped to form a heat applicator for changing back the color. For a doll, the cold sink applicator is used to change, for example, the natural color of the lips and cheeks to a make-up color, and a heat sink shaped to form a comb for combing the doll's hair and a heat applicator for returning the natural color of the doll's lips and cheeks through heat application.

摘要： An encapsulated thermoelectric heat pump, apparatus and method for manufacturing the encapsulated thermoelectric heat pump is disclosed. The encapsulated thermoelectric heat pump includes a plurality of spaced n-type and p-type thermoelectric elements arranged alternatively in rows and columns. The thermoelectric elements having opposing ends operatively connected to first and second metalized ceramic substrates. The first and second metalizations patterned to connect serially the thermoelectric elements. The space between the spaced thermoelectric elements is filled with a microballoon filled epoxy for substantially increasing the strength of the thermoelectric heat pump to withstand a stress of more than 2000 g's. The apparatus includes a mold cup holding the encapsulating material, a mold holding the thermoelectric heat pump mounted in the mold cup, and a vacuum means connected to the mold for drawing the encapsulating material upwardly through the spaces of the plurality of thermoelectric elements to fill the spaces for curing.
