The simple frame for the double-glass assembly comprises a frame body, a clamp is detachably installed on the outer side of the frame body, an installation plate is arranged at the rear end of the clamp, and an installation groove is formed in the installation plate; a mounting block is detachably mounted in the mounting groove, and a sliding block is arranged at the bottom of the mounting block. The installation effect is not influenced in the installation process, the frame body is simple and convenient, the mechanical load of the double-glass assembly can be increased, the deformation of the double-glass assembly is obviously changed after installation, the clamp is easy to fall off in the installation process by using an adhesive tape, and after the frame body is used, the adhesive tape does not need to be used in the clamp. And a clamp is directly contacted with the frame body, so that assembly bursting is reduced.

The invention relates to a method for operating an electric machine (4) of a rotary drive having a transmission mechanism (2) with a transmission mechanism backlash, the electric machine (4) being adjusted as a function of a target value (nEMsoll) of an adjustment variable, the adjustment comprising a proportional controller, and the adjustment comprising a proportional controller. The proportional gain factor (KP) of the proportional controller is varied as a function of the variable which deduces the powerless state of the transmission (2).

The invention relates to a pump (1) having an electric motor (2), which has a rotor (3) and a stator (5) surrounding the rotor, which stator is injection-molded with a plastic housing (4) and has an end-side opening (6), having a circuit board (7), which closes the end-side opening (6) in a sealing manner and, together with the stator (5), defines an interior space (9) through which a cooling fluid can flow, the rotor (3) is arranged in the interior space. The key point of the invention is that an elastic seal (10) is arranged between the plastic housing (4) and the printed circuit board (7), and at least two fastening elements (11) are arranged on the end face of the plastic housing (4), which fastening elements are connected to fastening contours on the printed circuit board (7).

The invention belongs to the field of magnetic confinement nuclear fusion, and specifically is a thermal shock experimental device for detecting the airtightness of connection components of a fusion device, comprising a vacuum chamber and a heating and measuring component, a turbomolecular pump and a gas storage tank connected to the vacuum chamber and the heating and measuring component, a leak detector and a mechanical pump connected to the turbomolecular pump, and a helium gas cylinder connected to the gas storage tank component; the device adopts an internal heating method, has good heating performance and excellent heat insulation effect, has a flexible structure, can increase mechanical load, and realizes multi-field coupling operation, and can be used for the airtightness research of high-temperature and high-pressure connection components to be tested in a magnetic confinement nuclear fusion device or other related technical fields in a high vacuum environment.
