    • There is provided a crack detection system in which a crack can properly be detected from a strain distribution of a part to be detected, as acquired without destroying a coating layer of the part to be detected, by applying heat to the part to be detected of a detection object, and analyzing, by a digital image correlation method, images as taken before and after applying the heat to the coating layer of the part to be detected. After taking the image of the part 51 to be detected of the detection object 50 by the imaging unit 10, the heat is applied by the heating unit, and change of the part to be detected, by heat, is also caused on the other surface side through the outer coating surface of the part to be detected, which is to be moved together with the part to be detected. Accordingly, images of every portions of the coating surface of the part to be detected are taken and the image analysis unit 30 analyzes the images before and after applying the heat to acquire a strain distribution of the part to be detected, so that the crack can be detected based on difference in a state of strain between a place where the crack exist and the other place. Therefore, taking the images of the part to be detected including its coating layer enables the analysis to progress without any problems to detect the crack, without removing the coating layer, thus improving the work efficiency of the detection operation.
    • 本发明提供一种裂纹检测系统,其能够通过对被检测部位加热而不破坏被检测部位的被覆层而从被检测部位的应变分布中适当地检测出裂纹, 检测对象,并且通过数字图像相关方法分析在将热量施加到待检测部件的涂层之前和之后拍摄的图像。 在通过摄像部10拍摄了检测对象物50的检测对象部位51的图像之后,利用加热部进行加热,另一方面,也通过加热使被检测部位发生变化 通过要与待检测部分一起移动的待检测部分的外涂层表面。 因此,拍摄待检测部分的涂覆表面的每个部分的图像,并且图像分析单元30分析在施加热量之前和之后的图像以获取待检测部分的应变分布,使得裂纹可以 基于存在裂缝的地方与其他地方之间的应变状态的差异来检测。 因此,通过拍摄包括涂层在内的被检测部位的图像,可以不产生任何问题地进行分析,而不会除去涂层而检测出裂纹,能够提高检测动作的作业效率。

    • An induction heating cooking device comprises: a cooking table having an auxiliary slit through which light passes; an induction coil for generating a magnetic field so as to inductively heat a cooking container placed on the cooking table; at least one light source disposed at the outer edge of the induction coil; an optical member for changing the traveling direction of light emitted the light source and concentrating the light, and a main slit through which light emitted from the optical member passes so as to form a flame image on the cooking container. The induction heating cooking device forms a virtual flame image on the lower surface of a cooking container at the time of operation of the induction coil, thereby enabling the heating state of the cooking container to be easily recognized.
    • 一种感应加热烹饪装置,包括:具有光线通过的辅助狭缝的烹饪台; 感应线圈,用于产生磁场以感应加热放置在所述烹饪台上的烹饪容器; 至少一个光源,设置在感应线圈的外边缘处; 光学构件,用于改变光源发射的光的行进方向并聚集光;以及主狭缝,光学构件发射的光穿过主狭缝以在烹饪容器上形成火焰图像。 感应加热烹饪装置在感应线圈运行时在烹饪容器的下表面上形成虚拟火焰图像,由此能够容易地识别烹饪容器的加热状态。
