Abstract: A saw blade has at least one carrier part that has at least one cutting side. The saw blade further has a multiplicity of inserts arranged so as to be spaced apart from one another. The inserts are made from a material, in particular a carbide, which is harder than a material of the carrier part. The inserts are each fastened to the at least one cutting side of the carrier part. The inserts each at least partially form at least two saw teeth.

Abstract: A saw blade for a hand-operated machine tool, in particular a reciprocating saw blade, includes a blade portion having a cutting edge and an opposite blade rear, in particular a cutting edge which is defined by a large number of saw teeth. The saw blade further includes a chucking shaft provided to be received by a clamping chuck of the hand-operated machine tool and a lower edge and an opposite upper edge. A transition region is constructed between the chucking shaft and the blade portion, in which a difference in spacing between the spacing of the lower edge and upper edge of the chucking shaft and the spacing between the cutting edge and the blade rear is bridged. A transition region lower edge has a raised portion, in particular a raised portion for stress relief, between the lower edge of the chucking shaft and the cutting edge.

Abstract: Ion beam lithography technique wherein a higher amount of radiation energy is deposited to predetermined regions in the bulk if a suitable substrate. By selecting the radiation nature, its energy and the irradiation parameters a structure can be created in the bulk of the material leaving the surface essentially untouched.
