摘要： 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.

摘要： 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.

摘要： Provided is a mask blank comprising a phase shift film A mask blank comprises a phase shift film on a transparent substrate. The phase shift film is made of a material comprising a transition metal, silicon, and nitrogen. A ratio of the total content of nitrogen and oxygen to the content of the transition metal is 12 or more and 19 or less in an internal region, wherein the internal region excludes a neighboring region of the phase shift film at an interface with the transparent substrate and a surface layer region of the phase shift film which is located opposite the transparent substrate.
