Title: Cut-sheet lamination by means of a laminator
Inventor: ANGER WOLFGANG
IPC: B32B38/00
Filed: 1987-11-07
Abstract: The invention relates to cut-sheet lamination by means of a laminator for applying a film section to one or both sides of a circuit board, having heated lamination rolls arranged opposite one another in a housing, to which rolls the circuit board and the film section are fed simultaneously in the roll region, where the circuit board is fed by means of draw-in rolls and the film is taken off a stock roll and fed to the circuit board via feed rolls, and a cutting device which cuts the film in accordance with the length of a circuit board according to sensor scanning is arranged in the region of the feed rolls. A known device of this type uses complex to-and-fro positioning means for feeding the film to the circuit board, the circuit board being stopped in the region of the lamination rolls, in particular during cutting of the film, which entails the risk that the photosensitive layer becomes overheated. The object of the present invention is to develop a cut-sheet lamination by means of a laminator of the type mentioned at the outset in such a way that good operational reliability at the same time as low production costs can be achieved using few and simple means and that the circuit boards pass continuously between the lamination rolls without any possibility of damage. The object is achieved by the cutting device being arranged in a pivotable manner on a lever ... Original abstract incomplete.

Title: Method for igniting an atmospheric oil burner with an electrically operated interference suppression ignition element
Inventor: STEINMANN HELMUT
IPC: F23N5/20
Filed: 1988-11-11
Abstract: In the case of a circuit arrangement for electrical ignition of an atmospheric oil burner, to achieve reliable ignition and a sufficiently long service life of the ignition element, the interference suppression ignition element is operated in a preset time sequence with different heat outputs: the pre-heating for evaporation of the oil to be ignited, with the aim of producing a reliably ignitable oil-air mixture, is effected with a lower heat output and over a longer time than the actual ignition, for which a higher heat output is supplied to the ignition element for a short time. Advantageously, this ignition sequence can be repeated a number of times and/or stopped by external intervention when ignition has taken place.

Title: Radio-frequency generator with automatic power control for radio-frequency surgery
Inventor: FLACHENECKER GERHARD PROF DR I
IPC: H03L5/02
Filed: 1989-02-15
Abstract: The invention describes a radio-frequency generator for radio-frequency surgery, with a power amplifier operating in switched mode, a modulation device for controlling the output, and a harmonics measuring device for measuring the harmonic frequencies of the generator frequency which are generated by the arc produced between the surgical probe and the tissue to be cut or to be coagulated. At the instant of start-up, the power amplifier is driven by an auxiliary oscillator. After the start-up, the drive of the power amplifier is switched over to selfexcitation, voltage feedback being selected when the load impedance exceeds a particular value, and current feedback when the load impedance falls below a certain value. During the feedback mode, the auxiliary generator is locked to the output frequency and output phase of the radio-frequency generator by means of a phase-locked loop. The harmonics measuring device contains a phase-controlled rectifier, the control signal of which is derived from the auxiliary generator. The advantage of such a generator lies in its low power dissipation, its high operational reliability and its low filtering complexity in the output circuit. <IMAGE>

Inventor: LEE HYO ICK
IPC: G10B3/12
Filed: 1989-03-02
Abstract: An improved key structure for electronic musical instruments in which the actuator 19 for pressingly contacting the rubber contact 12 is integrally formed with the dummy hammer 17; the connecting plate 18 is provided with an inclined bottom, in such a manner that the key-pressing direction corresponds with the moving direction of the dummy hammer, thereby making the movement of the actuator larger than the movement of the connecting plate; the hinge pin H of the dummy hammer is provided within the main body of the key 1; and the cross section of the rubber contact is substantially an equilateral triangle. The key structure of the present invention thus constituted overcomes the disadvantages of the structures of the prior art such as: the increased height of the overall key structure due to the external positioning of the hinge pin and the external installation of the dummy hammer; the non-constantness of the pressing force received by the rubber contact and the generation of reaction in the rubber contact due to the roundness of the shape of the rubber contact: and the increased length of the elastic leaf spring 27 due to the external positioning of the hinge pin, which fact made it impossible to use a compression coil spring or a tension coil spring in place of the leaf spring. <IMAGE>
