A protective case for use with a portable electronic device includes a protective shell including a cavity for receiving the portable electronic device and a pliable surface disposed in an opening of the protective shell. The pliable surface being adapted to transmit at least a portion of a mechanical force applied at an external surface of the protective shell to the control feature of the installed portable electronic device to actuate the control feature of the installed portable electronic device. The protective case also includes a feature disposed in a wall of the protective shell for accessing an electrical connector of the installed portable electronic device from outside the protective shell.

The invention provides metal powder constituted from metal particles. Each of the metal particles comprises a base particle having a surface and a metal material constituting at least the surface of the base particle. The base particle is subjected to a surface treatment with a fluorine type phosphoric acid ester. Further, the invention also provides an ultraviolet ray curable ink jet composition to be ejected by using an ink jet method. The ultraviolet ray curable ink jet composition comprises a polymerizable compound and metal powder constituted from metal particles. The metal particles of the metal powder are subjected to a surface treatment with a fluorine type phosphoric acid ester.

A printed circuit board includes an electrically conductive layer and a dielectric layer including a polymer. The polymer includes at least one of a carbon layer structure and a carbon-like layer structure.

A phosphor layer comprising a phosphor plate adhesively formed by a phosphor powder and an adhesive agent. The phosphor plate has a front side and a back side. The phosphor layer also have particles which are fixedly connected to the front and/or back side of the phosphor plate. Also provided in the present invention are a phosphor component, a corresponding light source, a projection system, and a method for manufacturing the phosphor layer. The phosphor component prevents adhesion between the phosphor plate and substrates thereof in high temperature conditions.

A method for marking an item including a shape memory polymer (SMP) having a visual readable and/or machine readable graphic element on the surface of the item. The method includes pretreating the surface of the item; coloring the surface of the item with a dye solution containing an organic dye and an organic solvent; cleaning and drying the surface of the item; and engraving by at least partially ablating the surface of the item. The dyeing process is suitable for coloring the surface of a shape memory polymer (SMP), wherein the information is engraved in a form of a code or other label on the colored surface. The coloring causes an increased contrast and thus facilitates machine readability of marking and coding without affecting the other properties of the SMP.
