Title: Method for producing etched printed circuit boards
IPC: H05K3/00
Filed: 1987-08-25
Abstract: Methods for producing printed circuit boards using a computer are already known. The computer is used to produce a so-called conductor track layout, which is used for the production of film masks. As a rule, these film masks must be produced outside the company which is developing the electrical circuit. This costs time and company secrets are passed off-site. The production of an etched printed circuit board can be carried out cost-effectively in-house using a method in which an ink-jet printer is driven by the computer in accordance with the conductor track layout which has been created. The ink-jet printer is used to deposit a covering liquid on the printed circuit board to be etched. The printed circuit board is subsequently etched, after which only the conductor tracks are located on the printed circuit board. The printed circuit board is complete. The method is particularly suitable for producing printed circuit board prototypes. <IMAGE>

Title: Biologically effective starting pulse formation of stimulation current devices for diagnosis and therapy
Inventor: NEUMUELLER HELMUT
IPC: A61N1/362
Filed: 1987-10-08
Abstract: Neurostimulation for diagnostic and therapeutic measures in the fields of neurology, neurophysiology and neurosurgery has been used for more than ten years. Depending on the object to be achieved, the nerve tissue is supplied in all the cases with electrical stimulating pulses which excite it. Clinical studies have shown that, apart from specific stimulation spectra, the form of the stimulating pulse fed to the patient is decisive for the diagnostic or therapeutic result. This results in the criteria that were decisive for the present invention. With the circuit measures described and using commercially available electronic components, the desired pulse shape according to Fig. 1 is generated by a low-impedance short circuit of the patient's output in front of a coupling capacitor and after the stimulating pulse has taken place. <IMAGE>

Title: Overvoltage protection circuit
Inventor: LOESEL WALTER
IPC: H03K17/79
Filed: 1987-10-16
Abstract: Electrical power supply apparatuses are known which act (by means of an optocoupler) on a control circuit fitted on the primary side, when an overvoltage occurs on the secondary side. In this case, it can be advantageous, when the overvoltage protection circuit has operated, to allow it to continue to act even after the overvoltage has decayed. This monostable response behaviour is intended to be achieved with an outlay for switching elements which is as low as possible. To this end, the monostable stage is formed from a phototransistor of the optocoupler and a switching transistor, the base connection of the phototransistor being connected to the switching transistor via a coupling resistor. Electrical power supply apparatuses.
