An electrical color control film includes: an underlying layer located on a metal plate; a first transparent conductive layer located on the underlying layer; an electrochromic layer located on the first transparent conductive layer; and a second transparent conductive layer located on the EC layer. The EC layer is configured in such a manner that color of the EC layer is controlled by electricity.

Electrical color control film and vehicle outer panel

A rotary atomization head is provided, which prevents discharged threads of a coating material from making contact with each other and from being unified. A rotary headincludes: a diffusion surfaceto diffuse the coating material toward an outer edge partby centrifugal force; and a plurality of groovesformed on the outer edge part. The plurality of groovesextends in a radial direction. The adjacent grooveshave different depths. The grooveshave the same width.

Rotary atomization head and coating device

A coating device includes a rotary head, a power supply part that applies a voltage to the rotary head, and a control part that controls the power supply part. The rotary head is configured so that a coating material is electrostatically atomized. The control part is configured so as to calculate a discharge current based on a total current flowing from the power supply part to the rotary head and a leak current, and control the power supply part based on the discharge current.

Coating device

A coating device is equipped with a rotary head, a drive unit, and an electric power supply unit. The rotary head is configured to be supplied with a coating material. The rotary head includes a diffusion surface that is configured such that the coating material is diffused toward an outer edge portion of the diffusion surface by a centrifugal force, and a plurality of groove portions that are included in the outer edge portion. The rotary head is configured to discharge a threadlike coating material from the groove portions. Also, the coating device is configured such that a diameter of the threadlike coating material is set equal to or larger than 0.03 mm and equal to or smaller than 0.1 mm and that the threadlike coating material is electrostatically atomized.
