摘要： A device for determining the temperature conductivity, the heat capacity and/or the thermal conductivity of a material sample. The device has a light emitter for exposing a front side of the sample to a light energy beam and a radiation detector for determining the temperature rise at a rear side of the sample facing away from the front side by detecting the radiation emitted there as a function of temperature, and a sample holder for holding the sample in a defined position.

摘要： In a generation method according to one embodiment, a master curve of a relationship between an extent of reaction and a heat treatment condition is generated using a thermal analysis result of a member. Also, in the generation method, first data that is related to a first heat treatment condition of a relationship between time and temperature is generated using the first heat treatment condition and the master curve. Also, in the generation method, a second heat treatment condition of a relationship between time and temperature is calculated using the master curve and a target condition for heat treatment.

摘要： A method of measuring thermal conductivity of a material includes focusing a modulated pump laser beam having a modulation frequency that induces a cyclical steady-state temperature rise at a spot of a material, focusing a CW probe laser beam at the spot and generating a reflected probe beam reflected from the spot on the material, the reflected probe beam having a magnitude of a reflectance signal as a function of the temperature of the material and being periodic corresponding to the cyclical temperature rise, measuring the magnitude of the reflectance signals of the reflected probe beam, and determining the thermal conductivity by fitting the power of the pump beam and the measured magnitude of the reflectance signal to a thermal model which is a function of a thermal conductivity of the material relating the radial heat flux to the temperature rise.

摘要： Disclosed is a thermal analyzer allowing observation of a sample. The thermal analyzer allows reliable observation of a film-like sample by solving a problem in that the film-like sample undergoes thermal deformation such as shrinkage or warping when the sample is heated or cooled. Further disclosed is a sample container for a thermal analyzer that is used to measure thermal behaviors of a sample attributable to heating or cooling of the sample and to observe the sample. The container includes a main body having a cylinder-shaped bottom and an open cylinder-shaped top and a transparent or translucent pressure plate that is in contact with an inner surface of the opening of the main body and presses down at least the pressure plate placed on a sample placed on the bottom surface of the main body.

摘要： A structure includes a substrate and a coating applied over the substrate, the coating containing particles sized between 30 and 250 micrometers. A proportion of the particles to the carrier is between 40 and 70 by volume percentage. In response to excitation of the structure by a controllable excitation source, a first instrument monitors behavior of the particles to determine a first condition of the structure thereby. In response to an absence of excitation of the structure by the controllable excitation source, a second instrument monitors behavior of the particles to determine a second condition of the structure thereby.

摘要： A machine learning device includes a virtual temperature model calculating unit having an equation including a first coefficient for determining a heat generation amount and a second coefficient for determining a heat dissipation amount. The virtual temperature model calculating unit is configured to calculate virtual temperature data by estimating a temperature of a specific portion of a machine by the equation using heat generation factor data. A thermal displacement model calculating unit is configured to calculate, using the calculated virtual temperature data and actual temperature data acquired from at least one temperature sensor mounted to a portion other than the specific portion, an error between thermal displacement estimated by the equation and actually measured thermal displacement, in which the virtual temperature model calculating unit performs machine learning to search for the first coefficient and the second efficient so that the error is minimized.
