Abstract
Official abstract text for this publication.
A time-dependent element of the present invention includes a time-dependent phase transition material that undergoes solid-solid phase transition developing with time after production irrespective of the presence of an external stimulus, in which one or more physical properties of the time-dependent element selected from a group consisting of composition, volume, transmittance, reflectance, electric resistance, and magnetic property change with time. A physical property temporal change prediction device includes a physical property temporal change prediction device body having the time-dependent element and is configured to predict a temporal change in one or more physical properties selected from a group consisting of composition, volume, transmittance, reflectance, electric resistance, and magnetic property.
First claim
Opening claim text (preview).
1 . A time-dependent element, comprising a time-dependent phase transition material that undergoes solid-solid phase transition developing with time after production irrespective of the presence of an external stimulus, wherein one or more physical properties of the time-dependent element selected from a group consisting of composition, volume, transmittance, reflectance, electric resistance, and magnetic property change with time; and the time-dependent phase transition material is composed of trititanium pentoxide including crystal grains of at least λ-phase trititanium pentoxide (λ-Ti 3 O 5 ). 2 - 9 . (canceled) 10 . The time-dependent element according to claim 1 , wherein the time-dependent phase transition material is composed of trititanium pentoxide including crystal grains of λ-phase trititanium pentoxide (λ-Ti 3 O 5 ) and β-phase trititanium pentoxide (β-Ti 3 O 5 ). 11 . The time-dependent element according to claim 1 , wherein the time-dependent phase transition material includes crystal grains of β-phase trititanium pentoxide (β-Ti 3 O 5 ) and λ-phase trititanium pentoxide (λ-Ti 3 O 5 ) at lower than 350° C. and has the property that at least a portion of crystal grains of β-phase trititanium pentoxide (β-Ti 3 O 5 ) and λ-phase trititanium pentoxide (λ-Ti 3 O 5 ) change into crystal grains of titanium dioxide (TiO 2 ) when the time-dependent phase transition material is heated to 350° C. or higher. 12 . A physical property temporal change prediction device, comprising a physical property temporal change prediction device body including a time-dependent element according to claim 1 , wherein the physical property temporal change prediction device predicts a temporal change in one or more physical properties selected from a group consisting of composition, volume, transmittance, reflectance, electric resistance, and magnetic property. 13 . The physical property temporal change prediction device according to claim 1 , wherein the physical property temporal change prediction device is composed of a card body. 14 . An electric circuit breaker, comprising a physical property temporal change prediction device according to claim 1 , wherein the electric circuit breaker predicts a temporal change in the electric resistance. 15 . An electric circuit breaker, comprising a physical property temporal change prediction device according to claim 1 , wherein the electric circuit breaker predicts a temporal change in the volume.
