摘要： In the production of a grain-oriented electrical steel sheet, instead of conventional inhibitors a novel (Al, Si)N inhibitor is utilized. This inhibitor is formed by obtaining an incomplete solution of Al and N and then nitriding the decarburization annealed steel sheet prior to initiation of a secondary recrystallization. The fine inhibitor can be formed in a large amount, thereby enhancing the magnetic flux density.

摘要： PURPOSE:To enable a microscopic image and an electron beam diffracted image to be simultaneously observed by displaying the electron beam diffracted image on a displayer according to the detected electron beam and producing the microscopic image from part of the electron beam through imaging lenses. CONSTITUTION:Electron rays discharged from an electron ray source 10 are irradiated upon a sample 14 located on an objective 16 through a convergent lens 12. Then, the electron rays pass through an objective 16 and then an electron beam diffracted image 36 is produced on the back focal surface 28 of the objective 16. At the same time, the main beam passes through the penetrating hole 48 of an electron beam detector 40 and a transmitted image is produced on the image surface 20 of the objective 16. The electron beam diffracted image 36 produced on the back focal surface 28 of the objective 16 is detected by an electron beam detector 40 consisting of many detection elements. Next, a displayer 44 receives the detection signal from the electron beam detector 40 through an amplifier 42 and then displays the electron beam diffracted image 36. On the other hand, the transmitted image is magnified by an intermediate lens 18 and the projection lens 22 and then the magnified image is produced on a fluorescent plate 26.
