Abstract: The output driver circuit of an integrated circuit has several pairs of driver circuits and driver control circuits as well as a control device. Each pair of driver control circuit and driver circuit forms a driver stage. The driver stages are connected in series. Based on the input signal of the output driver circuit, the control device switches the signal direction through the succession of driver stages in such a way that, at the time the output driver circuit is switched either on or off, the driver stages are switched in a time delayed manner, whereby current pulses on the feeding lines and disturbance voltages induced in inductive loads are reduced.

Abstract: The gene coding for human erythropoietin (EPO) was obtained from human genomic DNA. The gene used does not include sequences from regions at i 5' of the first translated ATG and ii 3' of the stop codon of the EPO gene. The gene was cloned into an expression plasmid for eukaryotic cells that have as sole expression control elements the early promoter of the SV40 virus and its polyadenylation signal. Recombinant cells resulting from transfection with genetic constructs used provide an unexpectedly high level of protein expression of 50 mg of recombinant EPO per liter of culture medium per day.

Title: Direct current electric motor of new design with limited counterelectromotive force
Inventor: GIOVANNINI SECONDO
IPC: H02K/
Filed: 1994-04-01
Granted: 1997-11-24
Abstract: This is a new direct current electric motor following a simple principle; economic and efficient so as to be simplified from the standpoint of mechanical construction and able to provide profoundly innovative performance features. The greatest benefit, besides its extraordinary versatility of use, lies in the energy efficiency which can be pushed beyond 100 percent. The fundamental purpose of the invention is twofold in that it easily allows the most broad regulation of the velocity, with possibility of braking and reversal of the direction of rotation, while also limiting the counterelectromotive force. The operating principle of this invention is to utilise the entire potentiality of the ferromagnetic components, exploiting to the maximum the mutual force of attraction. The second fundamental principle of the invention is to supply the excitation to the motor in a position where the counterelectromotive force is ineffective. This justifies the efficiency. <IMAGE>
