A system including an enclosure of a washing machine, a drum within the enclosure, a mixing unit, within the enclosure but separate from the drum and in fluid communication with the drum, a water supply unit coupled to the mixing unit, a reservoir having a conduit fluidly coupled to the mixing unit, and a container connecting assembly configured to fix a spout of a container to the reservoir. First, a resin film having photosensitivity is formed on a substrate 2. There are no continuous processes available for the synthesis of such compounds. The partial first dielectric layer is removed by using the conductor structures as etch mask. According to the present invention, there are provided a plastic lens, an optical molded article, and the like, which are excellent in physical properties such as transparency, thermal stability and impact resistance and are excellent in optical properties such as a balance between a refractive index and an Abbe’s number and a photoelasticity constant.
