    摘要： A liquid leak detection sensor has a sensitivity adjustable function, which adjusts a time to sense, that is, the sensitivity of a sensor regardless of whether the viscosity of a leaked liquid is high or low since a sensing position of the sensor can be adjusted according to the viscosity of the leaked liquid and the tilt of an installation place. The sensor includes a fixing connection fixture having a fixing plate with a fixing hole and a connection part formed with an angle adjustment protrusion, which are integrally provided; an insertion connection fixture into which the angle adjustment protrusion of the fixing connection fixture is inserted; a housing coupled to the insertion connection fixture and a substrate inserted into the housing and having a light-receiving unit for receiving light and a light-emitting unit for emitting light; and a lens part installed in the housing.

    摘要： An active magnetic bearing includes a bearing housing, a bearing stator, a bearing armature, a position detector, a jacket, and a stress buffering member. The bearing stator is accommodated in the bearing housing to support rotation of a rotor by using a magnetic force. The bearing armature is disposed to be spaced apart from the bearing stator by an interval and fixed to the rotor. The position detector is installed in the bearing housing to detect a position of the rotor. The jacket is interposed between the bearing stator and the bearing armature to seal a space between the bearing stator and the bearing housing. The stress buffering member connected to opposite ends of the jacket and the bearing housing, to buffer a stress generated due to differences between thermal exposition coefficients and temperatures of the bearing housing and the jacket.
