Title: Heat history meter using high molecular material
Inventor: KAWATE KOICHIRO
IPC: G01K11/16
Filed: 1993-07-14
Abstract: PURPOSE: To provide a heat history gauge which can determine quantitatively the degree of heat history, is usable repeatedly, and does not require temperature control before use by using a specific crosslinked high polymer as display material. CONSTITUTION: A high polymer with a crosslinking density of 2.5×10<-4> to 3.0×10<-3> mol/g is used as display material. The use of high polymer with physical reversibility is the requirement for repeated use. If the crosslinking density of the high polymer is not more than 2.5×10<-4> mol/g, the phenomenon of returning to a reproducible initial condition cannot be obtained, heat resistance becomes insufficient, and the service temperature range is limited. In excess of 3.0×10<-3> mol/g, the material is too hard to provide sufficient deformation when a display panel is extended or twisted, etc.  The heat history gauge uses the shape recovery of the high polymer as a function of time and the speed of the shape recovery as a function of temperature and can determine the elapsed time if the temperature is known, and the temperature (average) if the elapsed time is known.
