Abstract: A spirit level including first and second profile elements which can be displaced relative to one another in a telescopic manner and fixed relative to one another by means of a fixing element. In order to ensure that the first and second profile elements remain aligned with each other irrespective of their position, the first profile element is a hollow profile consisting of two sections which can be joined by means of the second profile element. The first section is joined to the second profile element and the second section can be moved along the remaining area of the second profile element. When the second profile element is at least partially uncovered by the second section, the second profile element can be subjected to the action of force in the direction of a profile wall of the second section of the first profile element.

Abstract: Different from conventional so-called mix-type film capacitors involving several disadvantages, in which the dielectric layers consist of a combination of a dielectric plastic resin film and an insulating paper sheet, the invention provides an all-film oil-impregnated capacitor in which the dielectric layers consist only of a plastic resin film such as a biaxially oriented polypropylene resin film (OPP film) suitable for use in microwave ovens. The all-film capacitor of the invention can be obtained and has satisfactory properties only when prepared by using specified materials including the OPP film, aluminum foil and capacitor oil and under specified conditions relative to the dielectric tangent values and dielectric capacity values before and after impregnation with a capacitor oil as well as the conditions in the step of oil impregnation.

Abstract: A stable wheel assembly has wheels, a connector, a wheel stand with a bracket and a resilient body. Each wheel has a center. The connector has two spindles and two protrusions. Each protrusion has a free end and an upright step integrally formed with the free end of the protrusion. The upright steps on the protrusions are mated with each other. The bracket is pivotally mounted on two protrusions with a fastener. When the scooter or electric motorcycle mounted the stable wheel assembly run on an uneven surface, the wheels is raised up and the protrusion connected to the raised wheels is pivoted around the fastener mounted inside the protrusion and bracket. Therefore, a scooter or an electric motorcycle with the stable wheel assembly can be prevented from turning over.

Abstract: A spindle motor structure includes a rotor, a stator accommodated mainly inside the rotor, and an internal roof magnet located on an inner roof surface of a rotor bell of the rotor. The internal roof magnet further has an inner rim and an outer rim. The inner rim is located projection-wisely within a range of a hollow shaft of the stator. The outer rim is located projection-wisely between an internal peripheral surface of the rotor bell and an inner edge of a coil of the stator. By providing the internal roof magnet inside the rotor bell, a magnetic field to immerse the stator can be generated to damp out possible operational noises and disturbance upon the spindle motor.

Abstract: Wind power plant with a wind turbine with a turbine shaft with which a generator shaft, which can be an extension of the turbine shaft, is connected to the rotor (12) of an electric generator. The rotor is radially surrounded by a stator, the turbine shaft is journalled in two bearing housings with bearings arranged on a base at the top of a tower, the base is pivotable around a vertical axis, and a motor is provided to effect the pivoting.
