Abstract: A silver-nano electronic-ink print heating element separation-type electric thermotherapy apparatus includes two or more silver-nano electronic-ink print heating elements that emit heat using a power source applied from a power source unit. The electric thermotherapy apparatus includes a control unit which receives the power source from the power source unit to output a power source on-off signal and a temperature control signal for controlling the two or more silver-nano electronic-ink print heating elements, and the silver-nano electronic-ink print heating elements emitting heat depending on the power source and/or a temperature applied using the control unit, whereby an integral heating element, such as an electric mat, an electric mattress, an electric cushion, a hot-water mat, and an electric carpet, includes two or more divided parts, and thus it is easy to separately use the parts of the heating element and to independently control the temperature for the heating parts.

Abstract: A refrigerator planar heating element is arranged inside a refrigerator to radiate heat. The refrigerator planar heating element includes a defrosting planar heating element including a first substrate having one surface on which a first pattern for radiating heat is printed with conductive ink, a second substrate having one surface on which a second pattern for radiating heat and having the same form as the pattern of the first substrate is printed with conductive ink, and an adhesive layer performing bonding such that the patterns of the first substrate and the second substrate are overlapped in a vertical direction. The invention has heating performance more excellent than that of conventional heating elements, and applies an inverse current patterning technique so as to make a current flow in opposite directions at both surfaces of a substrate, thereby effectively shielding electromagnetic waves.

Abstract: The present invention relates to a tracking-type photovoltaic generator. More particularly, the present invention relates to a tracking-type photovoltaic generator in which multiple solar modules are aligned into one or more rows so as to form a group, and the solar modules of the group aligned in the same row may rotate according to the location of the sun by means of the operation of a linear actuator.
