A computer for data processing and a method for data processing using a computer, each of which is used for reversing, with the aid of a circuit arrangement, the bit sequence of the information, which was coded with a reversible Huffman code, when an error occurs, so that the computer decodes the reversed bit sequences using a suitable code table. The first output power circuit is used for generating a first internal output voltage. The first body portion is pivotally coupled to the second body portion along the axis of symmetry. First and second bearing portions supporting the pickup housing to make the same movable are attached to the pickup housing and arranged on both sides with the objective lens therebetween. The process can also include the steps of continuously cooling and depressurizing the triterpene containing solution, where triterpene crystallizes out of the solvent, filtering the triterpene crystals from the solvent at room temperature and washing the triterpene crystals in fresh solvent. The auxiliary pump device is driven by torque applied to the transmission output shaft at least when the force flow is interrupted.
