Abstract: An actuating device has a linearly-movable fluidly operated piston drive (1). A pivot shaft (3) is movably, rotatably mounted in a housing (2). A lever arm (4) is connected with the pivot shaft (3) in a torsionally rigid manner. An adjustment mechanism (5) connects the piston drive (1) with the pivot shaft (3). A damping device (6) dampens movement of the lever arm (4). The damping device (6) is associated with the housing (2) and with the pivot shaft (3).

Abstract: An actuating device has an actuating member (2) pivotable in a first operating state about an axis (1). The actuating member (2) is connected in a torsion-proof manner with a toothed member (3). The toothed member (3), in a second operating state, prevents pivoting movement of the actuating member (2). The toothed member is coupled, in a lockable manner, with a detent member (4). The detent member 4 is movably mounted with respect to the axis (1).

Abstract: An actuating device has a drive element with a cylinder (1) and a piston (2) having a piston rod (3). A toothed rack (4) is provided outside the cylinder (1) on the piston rod (3). The toothed rack (4) is implemented to cooperate with a gear element (5). An actuating element (6), pivotable in relation to the drive element, is situated in a rotationally-fixed manner with the gear element (5). An intermediate gear element (7) is situated between the cylinder (1) and the gear element (5). The intermediate gear element (7) cooperates, on one side, with the toothed rack (4) and, on the other side, with the gear element (5).

Abstract: A disk storage has one or more disks provided with center holes. An electric motor extends coaxially through these holes and has an external rotor to the outer circumference of which the disks are secured so that they rotate with the rotor. A labyrinth seal is provided for at least reducing the escape of contaminants from the motor.

Abstract: A disk storage drive for mounting and driving at least one hard magnetic storage disk in a contaminant-free chamber is provided. A motor of the drive includes a stator, a bearing system, a rotor casing mounted to rotate around the periphery of the stator and a mounting arrangement for mounting the motor and disk in the contaminant-free chamber in a manner which minimizes the transfer of contaminants from the stator and bearing system into the contaminant-free chamber.

Abstract: Disk storage drive for receiving at least one storage disk provided with a central opening. The disk drive is provided with an outer rotor type driving motor having a rotor casing mounted by means of a shaft in a bearing system so as to rotate relative to a stator and receive the storage disk. The stator includes magnetically active parts. At least that part of the rotor casing receiving the storage disk is made from a non-ferromagnetic material and carries the shaft either directly or by means of a hub. A shield made from a ferromagnetic material is provided as an inner part of the rotor casing. The shield envelopes the circumference and one end of the magnetically active parts of the driving motor. The outer diameter of the rotor casing is smaller than the central opening of the storage disk.

Abstract: A magnetic disc storage driving mechanism is provided comprising a DC brushless driving motor having a stator and a rotor, a contaminant-free space without air intake provision for containing storage disks, bearings mounting the rotor for rotation and for driving a hub which receives at least one rigid storage disk within the contaminant-free space, and labyrinth seals arranged between the drive parts of the motor and the contaminant-free space containing the storage disk.

Abstract: To prevent damage to magnetic storage disks from sliding of the magnetic heads over the disk surface during running-out of the disk to a stop, the disk is positively braked when its drive is de-energized, so as to shorten the running-out time.

Abstract: An improved motor assembly including a brushless D.C. motor and an annular member defining a platform for the drive electronics and speed control circuits of the motor. The member is carried on a fixed support within the outer envelope of the motor and includes a thin disk-like body providing a pair of opposed surfaces for mounting the components of the circuits. The fixed support of the motor has a flat annular face surrounding the drive shaft of the motor, and the annular member engages and is secured to the flat face of the support in surrounding relationship to the shaft. In a preferred embodiment, the housing of the motor defines part of the rotor of the motor and is for rotation with the shaft. A flange is secured to the support near the opposite end of the shaft for mounting the motor on a fixed support, such as on the base of a housing forming a part of a disk drive unit.
