Title: Thin-film resistor using screen-printing and laser machining
Inventor: PANZER SIEGFRIED
IPC: H01C17/22
Filed: 1984-11-30
Abstract: A resistive film (2) is deposited on an insulating substrate (1). Contact pads (3,5) pass current into and out of the film. Elements of the resistive film are removed by screen-print etching and by machining with laser or electron beams. A pattern of square-angled structuring elements (9) is screen printed onto the film along the pathways taken by the current. Trimming slots (10), defining the pathways, are machined along lines of structuring elements intersecting them uniformly mid-way along their bases. Material adjacent to the trimming slots is raised to a high temperature during machining and the temperature coefficient of resistance and resistivity values are altered as a result. The structuring elements cut-down current flow near the edges of machined lines to preserve stability of the resistance value.

Title: Piston engine with alternating rotary movement
IPC: F02B75/02
Filed: 1985-02-04
Abstract: The invention relates to a device for converting a continuous rotary movement of a shaft 1 into an alternating rotary movement on another shaft, about which the piston or pistons 18 turn. The shafts 1 and 13 rotate at the same speed and in opposite directions by virtue of a system of gears 2, 9 and 11, and shafts 6 and 10. The shafts 1 and 13 alternately drive the shaft 8 by means of a system of connecting rods 4, 5 and 14, 16 which, when they are perpendicular to the radial axis of the crank pins 3, 7 or 21, 22, fully transmit the torque. When the planet wheels 15 or 20 are centred, the connecting shafts are free in relation to one another. A system of cams (not shown) controls and influences the trajectories of the planet wheels and connecting rods. The travel of the shaft 8 is one half revolution. The invention is intended for closed chamber displacement machines.
