    • In an insulating cover 50A according to the present invention, a dimension of each of an outer-circumferential-side cylindrical part 50c and an inner-circumferential-side cylindrical part 50b fitting in step parts 40 and 41 in an axial direction of a fastener body 25 is set large with respect to a tip covering part 50a covering a tip surface 26a of a fastening member 26. As a result, on an outer circumferential side and an inner circumferential side of the fastening member 26, a distance from a member 22 is sufficiently ensured by the cylindrical part 50b and 50c. The tip covering part 50a is thinner than the cylindrical part 50B and 50c. Therefore, when the fastener body 25 and the fastening member 26 are fastened together, the amount of deformation of the tip covering part 50a in a thickness direction can be made small.
    • 在根据本发明的绝缘盖50A中,沿着紧固件主体的轴向安装在台阶部40和41中的外周侧圆筒部50c和内周侧圆筒部50b的尺寸 25相对于覆盖紧固部件26的前端面26a的顶部覆盖部50a设定得较大。结果,在紧固部件26的外周侧和内周侧,与部件22的距离为 由圆柱形部分50b和50c充分确保。 尖端覆盖部50a比圆筒部50B,50c薄。 因此,当紧固件主体25和紧固构件26紧固在一起时,能够使顶部覆盖部50a在厚度方向上的变形量变小。

    • The objectives of the present invention are to prevent or inhibit the deterioration of optical systems that determine the longevity of an optical apparatus which delivers effects such as light transmission, diffraction, reflection, spectrum generation, and interference, and these combinations, and by so doing, decrease the frequency of maintenance operations such as window replacement and to reduce the costs for such operations. This invention is characterized by steps of creating a near vacuum zone with a presence of active energy to excite an oxidation reaction of carbon wherein the near vacuum zone faces the lighting surfaces of the optical system; generating negative ions or radicals in the near vacuum zone such as unstable chemical seeds containing oxygen atoms, such as OH radicals, OH− ions, ozone, O2− ions, O-radicals; and removing or reducing the accumulated carbon which deposits on the lighting surface, by reacting the deposited carbon with the negative ions or radicals. More specifically, the method according to this invention is characterized by the step of supplying active energy while supplying a flow of gases containing oxygen atoms such as water gas or oxidizing gas (for example, water vapor, oxygen, hydrogen peroxide, ozone or mixtures of said gases with inactive gases (including air)) into the near vacuum zone, thereby removing or reducing the accumulated carbon which deposits on the lighting surface by exciting the oxidation reaction of the accumulated carbon with the supplied active energy.
