摘要： A vibration motor includes a stationary portion, a vibrating body supported to vibrate in a lateral direction with respect to the stationary portion, and an elastic member positioned between the stationary portion and the vibrating body. The elastic member includes two or more first bent portions bent in a longitudinal direction orthogonal to the lateral direction, one or more second bent portions bent toward a side opposite to the first bent portion in the longitudinal direction, and flat portions connected to ends of the first bent portions and the second bent portions. The number of first bent portions is greater than that of second bent portions, the first bent portions and the second bent portions are alternately connected by the flat portions, and the maximum width of the first bent portions in the lateral direction is smaller than the minimum width of the second bent portions in the lateral direction.

摘要： A vibration motor includes a shaft, a stationary portion, a vibrating body, and an elastic member. The vibrating body includes a weight, first magnets, magnetic bodies, and one or more second magnets. Each first magnet has a ring shape and is magnetized in an inner or outer circumferential direction. Each magnetic body has a ring shape and is disposed between the shaft and a corresponding one of the first magnets. The one or more second magnets are magnetized in one direction, have a ring shape, and are interposed between the magnetic bodies corresponding thereto that are adjacent to each other in the one direction. The adjacent first magnets in the one direction are such that magnetic polarities of one of the first magnets at inner and outer circumferences thereof are opposite to magnetic polarities of another of the first magnets adjacent thereto at inner and outer circumferences thereof.

摘要： The present invention relates to a tamping beam device of a paving screed, in particular of a road paver, with a tamping beam arranged on a connecting rod, with a drive shaft connected to the connecting rod by means of an eccentric device, the eccentric device being configured such that a first and a second stroke adjustment position of the connecting rod can be adjusted depending on the direction of rotation of the drive shaft. Stroke adjustment is effected by means of an eccentric device with a thrust member comprising an inclined sliding surface and with an eccentric ring and a slide guidance. The present invention further relates to a paving screed as well as to a road paver having such a tamping beam device. A further aspect of the present invention finally lies with a method for changing the stroke of a tamping beam device.

摘要： A vibrator-mounted holder is attached to a casing of a vibration generator which moves a vibrator to generate a vibration when used. The vibrator-mounted holder includes a vibrator, a vibrator retention unit retaining the vibrator, a fixing unit fixed to a casing, and an arm. The vibrator includes a magnet having a plate shape parallel to a horizontal surface and a yoke arranged on the magnet. The arm connects the fixing unit to the vibrator retention unit, and supports the vibrator retention unit in a manner that the vibrator retention unit is displaceable with respect to the fixing unit. The yoke has a projecting portion which is projected downward and fixed to the vibrator retention unit. The arm is connected to a portion, at which the projecting portion is arranged, within the vibrator retention units.

摘要： The invention relates to a method for determining the flow or the flow rate of a medium in an electrically conductive object, in particular a pipe (1) or a pipeline, through which a medium flows. At least one ultrasonic wave (16) is produced by means of a transmitting transducer (11) in the object and is injected into the medium as a longitudinal wave (8) on an inner side of the object, and an ultrasonic signal, coming at least partially from the longitudinal wave (8), is received by the receiving transducer (12), at a spatial distance from the injection point and is used to evaluate the flow or the flow rate. Said transmitting transducer (11) produces, preferably in the absence of an acoustic coupling with the surface of the object, a first variable magnetic field in an area close to the surface of the object, in particular metallic, and a first ultrasonic wave is produced in said area by means of the interaction of said variable magnetic field with a static or quasi-static magnetic field. Said transmitting transducer (11) also produces an additional variable magnetic field in the area of the object and an additional ultrasonic wave is produced in said area by means of the interaction of the variable magnetic field with a static or quasi-static magnetic field, said other ultrasonic wave is superimposed on the first ultrasonic wave such that an amplitude of a resulting wave in the direction of the receiving transducer (12) is increased and is reduced in the direction away from said receiving transducer (12). Preferably, the first and the second magnetic fields are produced by two high frequency bobbins (18, 19) of the transmitting transducer (11). The invention also relates to a device for carrying out said inventive method.
