Abstract: An endoscope with an insertion tube having a proximal passive flexible section and a distal bending section. Cuts are provided in the proximal passive flexible section. Adjacent cuts are unequally spaced in the proximal passive flexible section. The proximal passive flexible section has secondary cuts adjacent to main cuts, wherein the secondary cuts are arranged closer in the longitudinal direction of the proximal passive flexible section to the adjacent main cuts on one side of the secondary cuts than to the adjacent main cuts on the other side of the secondary cuts. The main cuts extend along the circumference of the proximal passive flexible section in an interrupted manner. The proximal passive flexible section includes the main cuts, wherein at least within a subzone in the proximal passive flexible section, the main cuts are unequally spaced from each other in the longitudinal direction of the proximal passive flexible section.

Abstract: A ring-shaped glass spacer is to be arranged in contact with a magnetic disk in a hard disk drive device. A film that contains at least one of tin oxide, zinc oxide, and titanium oxide is formed on each surface of a main surface, and an outer circumferential edge surface, and an inner circumferential edge surface of the glass spacer. The thickness of the film on a center portion of the outer circumferential edge surface of the glass spacer is larger than the thickness of the film on a center portion of the inner circumferential edge surface of the glass spacer.

Abstract: A mask blank 100 has a structure in which a pattern-forming thin film 3 and a hard mask film 4 are formed on a transparent substrate 1 in this order. An Si2p narrow spectrum obtained by analyzing the hard mask film by X-ray photoelectron spectroscopy has a maximum peak at a binding energy of at least 103 eV. An N1s narrow spectrum obtained by analyzing the hard mask film by X-ray photoelectron spectroscopy has a maximum peak below a detection lower limit value. In the hard mask film 4, a content ratio (atomic %) of silicon and oxygen is Si:O=1:less than 2.
