Disclosed is an apparatus for detecting a defective component includes an infrared camera configured to capture an image of a test-target component in a production process, and a processor configured to measure a temperature of the component based on the image captured by the infrared camera and identify that the component of which temperature is out of a range of a reference value is defective. In addition, a database of various causes of defect is established, and an expected cause of defect for a defective component or a retest component is reasoned out from the database based on the measured temperature.

A method of detecting and identifying leaking underground pipes for properties having a slab or other type of foundation with a plurality of manifolds utilized to distribute water in the plumbing system of the property. The method includes identifying and detecting a starting fixture to start testing to determine a possible location of an underground leak and performing a series of temperature test checks to determine a number of relevant factors, including, whether an underground leak is before or after a manifold, the feed lines and/or distribution lines of a manifold, and a destination of the distribution lines of the manifold. The series of temperature tests using heating and cooling elements identifies which pipeline contains the underground leak and identifies the point where the pipeline enters a ground (Point A) and the exit point where the pipe exits a ground (Point B) in order to mark these specific pipelines.

A method for monitoring an attachment area during laser welding of bent bar-type conductors containing copper, includes the steps of arranging a first bar-type conductor relative to a second bar-type conductor in partially overlapping fashion and welding the first and second bar-type conductors to one another using a processing laser beam, the welding including forming a weld bead interconnecting the bar-type conductors to one another. After the welding, at least one measurement variable is measured on at least one portion of the weld bead, wherein the at least one measurement variable changes with the temperature of the weld bead as a function of the time during a cooling down of the weld bead. A parameter depending on a heat capacity of the weld bead is determined from the at least one measured measurement variable, and the attachment area qualitatively or quantitatively determined from the parameter.

A non-transitory computer readable recording medium has an estimation model according to one aspect of the present invention recorded thereon, and the estimation model is included in a program to be executed by a computer and outputs output data estimated based on input data received. In response to receiving, as the input data, a change over time in an intensity of energy emitted from a sealing part of an object subjected to a sealing process through bonding, the estimation model estimates at least one of whether sealing of the object is good or whether the sealing of the object is defective and outputs an estimation result as the output data, the change over time being calculated based on an intensity of energy emitted at each of a first time point and a second time point that is later than the first time point.

Disclosed is a thermal insulating shipping container with a five-sided box wherein a bottom and four sides all have an inner layer of corrugated polymer, a middle layer of shrink-wrapped panels with each panel being a vacuum panel, and an outer layer of corrugated polymer. The container is formed by inserting polyurethane liquid into the gaps and spaces between the shrink-wrapped panels and the inner and outer layers and foaming the polyurethane liquid and allowing it to harden. Weather stripping may be adhered to the edges of the container which are opposite to the bottom of the container.

Provided are a structure inspection method and a structure inspection system capable of easily detecting an abnormal location and inspecting an internal state of the abnormal location in detail. The structure inspection method includes: a step of capturing a thermal image of a surface of a structure with an infrared camera; a step of detecting a first region estimated to have an internal abnormality, on the basis of the thermal image; and a step of measuring an internal state of the first region in a case where the first region is detected. In the step of measuring the internal state of the first region, the internal state of the first region is measured by capturing an image that visualizes the internal state of the first region using an electromagnetic wave or an ultrasonic wave.
