    • The present invention aims to provide a method of shot-peening treatment that substantially improves the durability (particularly, heat check resistance) of the treated surface of the steel products in the process of treating by shot peening (hereafter, “SP”) the surface of the steel product that is the work to be treated and that was treated by heat hardening.The SP treatment of the present invention that gives the SP treatment to the steel product that was heat-treated and that is a work to be treated comprises the first SP treatment that removes the compound layer (white layer) and a second SP treatment that gives compressive residual stress to the first SP treated surface that was treated by the first SP treatment where the second SP treatment is carried out only to the products where it has been proved by the non-destructive inspection that the compound layers are removed by the first SP treatment.
    • 本发明的目的在于提供一种喷丸处理方法,其特征在于提高了在喷丸硬化处理(以下称为“SP”)表面处理钢板的处理表面的耐久性(特别是耐热性) 的钢铁产品是待处理的工件,通过热硬化处理。 对被热处理的钢产品进行SP处理的本发明的SP处理是被除去化合物层(白色层)的第一SP处理和给出 通过第一SP处理处理的第一SP处理的第一SP处理表面的压缩残余应力,仅进行第二次SP处理的产品,通过非破坏性检查证明化合物层被第一SP除去 治疗。

    • Provided is an imaging apparatus capable of obtaining images of an object at high precision even if the intensities of illuminating light temporally varies. The imaging apparatus 1 comprises a lamp unit 10, lens 21, a half mirror 22, a lens 23, a liquid crystal tunable filter 24, a lens 25, a reference mirror 31, a reference mirror 32, an image capturing unit 40, an operation unit 50, and a display unit 60. The reference mirrors 31 and 32 are provided at the positions to which illuminating light led by an optical system for illuminating light is irradiated and which are located at a part of the view of the image capturing unit 40. The operation unit 50 corrects the value of the image part of the object 2 by using the value of the image part of the reference mirrors 31 and 32 out of the images captured by the image capturing unit 40.

    • A method of shot peening in which with respect to a carburized and quenched metal part, only its surface abnormal layer detrimental to the fatigue strength thereof is scraped without scraping of the martensitic structure underlying the surface abnormal layer, namely, in which the fatigue strength can be rendered stable and enhanced without surface cracking. As bombardment shot, use is made of a shot with hardness higher than that (first hardness) of the surface abnormal layer occurring at a surface layer portion of metal part prior to shot peening but lower than that (second hardness) of the martensitic structure.
    • 一种喷丸硬化方法,其中相对于渗碳淬火的金属部件,只有其不利于其疲劳强度的表面异常层被刮去,而不会刮擦表面异常层下面的马氏体结构,即其中疲劳强度可以 使之稳定和增强,无表面开裂。 作为轰击射击,使用硬度高于在喷丸硬化之前在金属部件的表面层部分发生但低于马氏体结构的(第二硬度)的表面异常层的(第一硬度)的喷丸。
