In a method for producing an electrophotographic recording material composed of a dual layer of amorphous and crystallized selenium applied to an electrically conductive substrate, tellurium is vapor-deposited in a vacuum onto the surface of the conductive substrate to a layer thickness of about 0.5 to about 5 nanometers to form a tellurium layer, and selenium is vapor-deposited onto the tellurium layer to a layer thickness of about 20 to about 100 microns to form the dual layer of amorphous and crystallized selenium.

A securing device for a vehicle locking mechanism includes an actuating member which can be moved between a locked position and an unlocked position by way of a key. The member has a stop face which faces in the direction of its movement from the locked to the unlocked position. A locking element is arranged to be movable in response to electromagnetic driving means to a position confronting the stop face when the actuating member is in the locked position. Circuit means are provided to energize the driving means in response to operation of the key.

A hand-operated machine tool device, in particular for an angle grinder, includes a housing region and at least one operating element. The housing region is at least substantially rod-shaped and is configured to be used as a main gripping element. The at least one operating element extends in the housing region in a main extension direction of the housing region. The hand-operated machine tool device also has a least one mounting which supports at least one operating face of the at least one operating element such that the at least one operating element is configured to pivot about at least one axis aligned at least substantially parallel to the main extension direction.

A carbon brush with a disconnection apparatus in a cavity in a brush body includes a disconnection body and a prestressed compression-spring body. The disconnection body consists of an electrically insulating material, and the prestressed compression-spring body is configured to act resiliently on the disconnection body. The compression-spring body is formed together with the disconnection body as a short component with a short axial length. In one embodiment, the compression-spring body is in the form of a spring with a plurality of spring turns which, at least in the prestressed, compressed state, are at least partially located one inside the other, shortening them.

A machine tool switching device, in particular for portable machine tools, includes at least one switching unit that has at least one movably mounted operating element for actuating a mechanical, electrical, and/or electronic switching element. The machine tool switching device further includes at least one blocking device for blocking at least one movement of the operating element. The blocking device includes at least one movably mounted release element provided to lift the blockage of the operating element. The release element is mounted on the operating element so as to be movable in a translatory manner.

A hand-held power tool is provided with a housing comprising two separate and interconnected housing parts, one of which is designed as a handle part for holding and guiding the hand-held power tool. At least one housing part is associated with a vibration reduction element designed as a spring element. The vibration reduction element is arranged in an intermediate space between the handle part and the other housing part.
