A node of a C company verifies transaction data received from a node of a B company, the transaction data proposing addition of a subject substance to a restriction list. When the node of the C company determines that information indicating that a new proposed subject substance falls under a restricted substance is incorrect by obtaining data on the restricted substance, for example, from the outside (a server apparatus or the like in an external group) and checking whether or not the subject substance falls under the restricted substance, the node of the C company does not approve the proposal for addition of the new subject substance to the restriction list but transmits transaction data that denies the proposal to the node of the B company (an arrow B).

Information management system

When information on a chemical substance is disclosed by a node of an upstream company (S), a controller updates product composition data (S) and determines whether or not the disclosed information on the chemical substance is to be kept secret (S). When the controller determines that the disclosed information on the chemical substance does not have to be kept secret (NO in S), it adds the information on the chemical substance (a restricted substance) received in Sto update public data (S) and generates transaction data including the public data and transmits the transaction data to a node of a target downstream company (S).

Information management system and information management method

A vehicle structure capable of obtaining both the adhesive property and stripping performance of a coating. The vehicle structure includes an outer panel and an exterior component, and a coating formed by applying easily strippable coating material onto the outer panel and exterior component. The coating includes a design portion formed on the outer surface of the outer panel and exterior component, and a non-design portion coupled to the design portion and formed on the side end surface and backside surface of the outer panel and exterior component. At least one start point for stripping the coating is provided in at least one of the non-design portion of the coating, or the side end surface or backside surface of the outer panel and exterior component.

Vehicle structure

An information management system includes information management apparatuses belonging to A to D companies, respectively, and a platform provider. When a new chemical substance is added as a result of revision of laws and regulations etc. to chemical substances designated under the laws and regulations, the platform provider updates a restriction list and transmits transaction data that proposes update of restriction lists in distributed ledgers to the information management apparatuses. Each of the information management apparatuses approves the transaction data and updates the restriction list thereof. Each of the information management apparatuses discloses information on a chemical substance included in the updated restriction list to an information management apparatus in a downstream company.

A five-layer thin film structure including a reflector, a high refractive index layer on or encapsulating the reflector, and a metallic iron absorber layer on or encapsulating the high refractive index layer. The reflector has a thickness from 10 nm to 5000 nm, the high refractive index layer has a thickness from 5 nm to 500 nm; and the metallic iron absorber layer has a thickness from greater than 0 nm to 50 nm.

Five-layer thin film structures comprising a metallic iron absorber

A discrete metallic particle having a metallic material, and a coating covering at least a portion of the metallic component. The discrete metallic particle has a thickness from 50 nm to 1000 nm, and the discrete metallic particle has a skin depth δ of greater than or equal to 1.0 μm in a frequency range from 20-40 GHz. The skin depth δ is calculated by: Where δ is skin depth in meters (m); ρ is resistivity in ohm meter (Ω·m); f is frequency of an electromagnetic radiation in hertz (Hz); μis permeability; and μis relative permeability of the metallic material.

Coated discrete metallic particles and multilayer structures comprising reflective core layers

A multilayer thin film that reflects an omnidirectional structural color having a reflective core layer comprising a metallic material, a second layer extending across the reflective core layer, a third layer extending across the second layer, and an outer layer extending across the third layer.
