Abstract: The invention relates to an endoscope having an endoscope head with a working channel for guiding microtools, and an Albarran lever that is insertable on and detachable from the endoscope head, and having a tool guide surface with which a tool that is guidable through the working channel may come into contact in order to be deflected in the lateral direction of the endoscope head. An Albarran lever arrangement space is delimited by two flank sections of the endoscope head that extend in the distal direction. An Albarran lever pivot shaft, from which a shaft section protrudes with respect to the Albarran lever arrangement space with a length, is supported in one of the flank sections. The Albarran lever has a shaft insertion hole for inserting the shaft section, and has a width in a direction that is parallel to the shaft insertion hole.

Abstract: A method for manufacturing a magnetic recording medium includes the steps of (a) forming a perpendicular magnetic recording layer and (b) applying an ion beam to regions between tracks of the perpendicular magnetic recording layer so as to form separation regions for magnetically separating the tracks from each other. In the step (a), a continuous film layer composed of a multilayer film is formed, and CoB layers and Pd layers are laminated in the multilayer film. In the step (b), the CoB layers and the Pd layers are melted by the ion beam so as to form an alloy of metals contained in the CoB layers and the Pd layers to thereby form the separation regions.

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.
