    • The invention relates to a device and a method for generating a force and/or a movement. The force and/or the movement are generated or the energy of the force and/or the movement is stored by utilizing a magnetic field. The magnetic field is generated with a charge current circuit (4) including a charge part and a structure generating the magnetic field without a separate winding. The charge current circuit (4) is used either to generate the magnetic field producing the force and/or the movement, or the force and/or the movement generates a variable magnetic field, the current induced by which is conducted to the charge part of the charge current circuit (4).

    • Material is extruded with a device comprising at least two stators (1,2) one within the other and, between them, a rotor (3) in the shape of a convergent cone, the material being extruded from the device by rotating the rotor (3). The rotor (3) comprises openings (9), through which the material is led. The stators (1,2) comprise continuous grooves (8) for conveying the material out of the device. The stator grooves (8) alternately become lower and deeper, said grooves (8) being arranged such that when the groove of the inner stator (1) is low, the point of the groove of the outer stator (2) on the other side of the rotor (3) at a corresponding point is deep and vice versa.
    • 材料用包括至少两个定子(1,2)的装置挤出,并且在它们之间具有锥形形状的转子(3),所述材料通过旋转转子而从装置挤出( 3)。 转子(3)包括开口(9),材料通过该开口(9)被引导。 定子(1,2)包括用于将材料输送出设备的连续凹槽(8)。 定子槽(8)交替地变得越来越深,所述槽(8)被布置成使得当内定子(1)的槽较低时,另一侧的外定子(2)的槽的点 在相应点处的转子(3)是深的,反之亦然。

    • The present invention relates to an electroacoustic transducer where the voltage of a capacitive acoustic element is controlled by charging and discharging the charge of the element via an inductance (L) by fast switches (K1, K2). In the case energy unconverted into the acoustic energy of the transducer can be transferred to an energy storage of an electrical circuit formed by the inductance (L) and the capacitance (C1, C2, C0) during each control sequence and in this way the transducer can be made to operate with a good coefficient of efficiency.
    • 本发明涉及一种电声换能器,其中通过快速开关(K1,K2)通过电感(L)对元件的电荷进行充电和放电来控制电容式声学元件的电压。 在转换器的声能中未转换的能量可以在每个控制序列期间被传送到由电感(L)和电容(C1,C2,C0)形成的电路的能量存储器,并且以这种方式,换能器 可以使其具有良好的效率系数。
