Abstract: A method for registering a wireless device by a terminal in a wireless communication system is provided. The method includes obtaining connection information for the wireless device by scanning a recognition code of the wireless device in a first mode, transitioning to a second mode based on the connection information and receiving a connection request from the wireless device, performing a connection operation to the wireless device to transmit network access information to the wireless device, and transitioning to the first mode, and registering the wireless device upon detecting connection of the wireless device to a network in the first mode.

Abstract: A method for producing an intermediate material for a cooking device according to an embodiment of the present invention comprises the steps of: repeating a cycle of applying a dispersion of a fluororesin and an inorganic filler or a dispersion of a fluororesin alone to a supporter and firing the applied dispersion so as to form a multilayered fluororesin film, followed by exfoliating the multilayered fluororesin film from the supporter to acquire the multilayered fluororesin film beforehand; providing the pre-acquired fluororesin film on a metal-substrate; and thermally compressing the fluororesin film and the metal substrate. In addition, an organic compound-containing primer or adhesive is not used in the thermocompression step.

Abstract: A cooking utensil according to the present invention includes a cooking utensil body A which is composed of a laminate including a metal substrate 1 and a fluorine resin film 2 laminated on the metal substrate 1, and the fluorine resin film 2 forms an inner surface of the cooking utensil body A, wherein the fluorine resin film 2 has a thickness 20 to 300 ?m, a thickness deviation of 0.1 to 10 ?m, and a surface roughness of 0.1 to 10 ?m. The fluorine resin film 2 is manufactured by a casting method, a cutting method, a calender method, or an extrusion molding method, thereby having uniform thickness and surface roughness. The fluorine resin film 2 has the uniform thickness and surface roughness, thereby improving non-stick characteristics.
