Patent number: 11725709Abstract: A rotation damper has a housing, a magnetic field source and a damper shaft designed as a hollow shaft, and a coupling rod arranged inside the damper shaft. The hollow shaft and the coupling rod form interacting transmission units and convert a relative axial movement of the coupling rod into a rotational movement of the hollow shaft. A displacer unit is arranged in the housing. The displacer unit includes the damper shaft and meshing displacer components that are rotatable in relation to each other. The displacer unit contains a magnetorheological fluid as the working fluid and can be operated thereby. The magnetic field source is configured for applying a magnetic field to the displacer components in order to dampen a rotational movement of the damper shaft.Type: GrantFiled: December 12, 2017Date of Patent: August 15, 2023Assignee: INVENTUS Engineering GmbHInventor: Stefan Battlogg

Patent number: 5630187Abstract: A lens device that is not affected by changes in environmental conditions and is capable of manual and automatic focussing of the lens. Specifically, the lens device generates an appropriate operational load during manual operations of the lens using a simple structure. The lens device includes a lens barrel containing a lens holding barrel holding the lens. The operation ring has the ability to rotate and is fitted around the outer periphery of the lens barrel. The lens drive device includes a motor, a deceleration device, a motor drive circuit, and a variable resistor. The motor has the ability to generate electricity. The selection switch selectively connects the motor to either the motor drive circuit or the variable resistor. During automatic operation, the motor is connected to the motor drive circuit. The motor drive circuit is the power source of and drives the motor. The driven motor rotates the operation ring to adjust the focus through the deceleration device.Type: GrantFiled: June 22, 1995Date of Patent: May 13, 1997Assignee: Nikon CorporationInventor: Tomoaki Kawamura
