Patent number: 6157476Abstract: In a transceiver component for optical data transmission a transmitter, a receiver and at least one integrated circuit are arranged in a single housing. The housing has a number of terminals. One terminal of the transceiver component is provided solely for feeding the driver current to the transmitter. Consequently, it is possible to connect the transmitter with its high current consumption directly with the non-stabilized power supply such as, for instance, the mains adapter, the rechargeable battery pack or the batteries. The stabilized power supply can then be dimensioned correspondingly smaller and be produced at lower cost.Type: GrantFiled: December 22, 1997Date of Patent: December 5, 2000Assignee: Temic Telefunken Microelectronic GmbHInventors: Jorg Angerstein, Werner Schairer, Ulrich Wicke

Patent number: 5472915Abstract: The invention relates to an opto-electronic component having a narrow aperture angle. The conventional design of components transmitting radiation or reacting to radiation and concentrating that radiation with the aid of lenses results, on account of the increasing distance between the lens and the semiconductor chip, in increasing component dimensions in the radiating or detecting direction with an increasingly narrow aperture angle. In accordance with the invention, a parabolic or approximately parabolic reflector is provided that is connected to a support strip supporting the semiconductor chip such that the latter is as close as possible to the focal point of the parabolic or approximately parabolic surface of the reflector. The reflector is preferably connected to the support strip by engaging elements and surrounded by a housing.Type: GrantFiled: September 16, 1994Date of Patent: December 5, 1995Assignee: Temic Telefunken microelectronic GmbHInventors: Werner Schairer, Jorg Angerstein, Siegfried Giebler, Jurgen Riedel, Thomas Mistele

Patent number: 5350943Abstract: A semiconductor assembly with a metal frame configuration is described, having a semiconductor component (HL) on a carrier section (T) of a ground strip section (M). The ground strip segment has an extension section (V) with which it is extended beyond said carrier section and is both folded over in relation to said carrier section and of sufficient length that it covers said semiconductor component in order to shield it electromagnetically.In this assembly, the ground strip section has a multiple function. It is used not only for carrying and contacting of electrical components, but also acts at the same time as electromagnetic shielding for a semiconductor component, for example for the radiation detector of a remote control reception module.Type: GrantFiled: March 22, 1993Date of Patent: September 27, 1994Assignee: Temic Telefunken Microelectronic GmbHInventors: Jorg Angerstein, Siegfried Giebler, Thomas Mistele, Werner Schairer, Helmut Scheidle

Patent number: 4697880Abstract: The invention relates to an optical system comprising a semiconductor laser and an optical instrument collimating the laser light. In accordance with the invention, the semiconductor laser and the optical instrument are accommodated in separate holders which are adjusted relative to one another in such a way that a criterion relating to the laser light is optimally fulfilled. After completion of the adjustment, the two holders, both forming the external housing of the entire system, are joined to one another.Type: GrantFiled: April 8, 1985Date of Patent: October 6, 1987Assignee: Telefunken Electronic GmbHInventors: Jorg Angerstein, Dieter Mutz, Elmar Wagner

Patent number: 4613884Abstract: The invention relates to a controllable semiconductor circuit element consisting of a vertical thyristor comprised of four zones of alternating conductivity types and arranged in a semiconductor disk, with the two load current connections located on the top surface and on the bottom surface of the semiconductor disk respectively. According to the invention, the semiconductor disk comprises an additional controllable circuit element with a lateral zone structure on the top surface of the semiconductor disk. Zones of this additional circuit element are linked with zones of the vertical thyristor in such a way as to enable the vertical thyristor to be indirectly ignited by ignition of the lateral circuit element.Type: GrantFiled: October 31, 1983Date of Patent: September 23, 1986Assignees: Licentia Patent-Verwaltungs GmbH, Telefunken Electronic GmbHInventors: Jorg Angerstein, Dieter Silber
