Abstract: The present invention provides a design-for-product creating system and a design-for-product processing system. In the design-for-product creating system, a product vendor provides a user with a product design program, which enables the user to view virtual products that are graphics expressing designs created by the product vendor, and virtual part data representing virtual parts that constitute each virtual product. The user downloads the product design program and digital part data into his/her own computer, uniquely designs a product or part in a desired manner, and asks the product vendor over the Internet or the like to manufacture a product or part of the unique design. The product vendor in turn manufactures a product or part according to the desired unique design for a product or part provided by the user, and supplies the product or part of the unique design to the user.

Abstract: A radio controlled watch comprises a case made of a nonconductive material, having a middle (30), back (31) and a shield (32), and an antenna (38) provided in the case, and a part of the case is covered by an exterior member (47) made of conductive material.

Abstract: A decorative item and method for making same, such as an exterior part of a timepiece, wristwatch band and the like, includes a basis material of stainless steel having a carburized hardened later thereon in which carbon is diffused so as to form a solid solution in which crystalline chromium carbide is not formed and at least one hard coating is deposited on the carburized hardened layer of basis material, wherein the hard coating has a surface hardness greater than that of the carburized layer.

Abstract: Disposing the titanium or titanium alloy in a vacuum vessel, and applying annealing treatment thereto by heating (a heating process); feeding a mixed gas consisting primarily of nitrogen with a trace of oxygen component into the vessel, and heating inside the vacuum vessel at temperatures in the range of 700 to 800° C. in a predetermined reduced pressure condition for a predetermined length of time such that nitrogen and oxygen are diffused into the interior of the titanium or titanium alloy from the surface thereof so as to pass into solid solution therein (a hardening treatment process); and cooling the titanium or titanium alloy to room temperature after the hardening treatment process (a cooling process), are carried out. After completion of the processes described above, a hard surface layer 101 is formed in the surface region of the titanium or titanium alloy 100.
