Abstract: A light-triggered thyristor module incorporates light-triggered thyristors and associated fiber optics for transmitting light from a remotely located light source. The isolated light-triggered thyristor module includes a housing having an anode contact, a cathode contact and an electrically grounded base plate. In the housing is disposed a thyristor in a semiconductor body. The semiconductor body has a first major surface and an opposing second major surface. The thyristor has an optical gate, cathode emitter and base regions disposed adjacent the first major surface and anode emitter and base regions disposed adjacent the second major surface. A cathode conductive layer and an anode conductive layer contact the first and second major surfaces, respectively, of the semiconductor body, and are electrically connected to the cathode and anode contacts, respectively, of the housing. Disposed in and penetrating the housing is also means for receiving an optical fiber. Additionally, a fiber optic locator member for holding and supporting an optical fiber is disposed adjacent the optical gate of the thyristor. The locator member is of an electrically non-­conductive and optically neutral material such that light passing through a fiber within the locator member is substantially unaffected by the locator member. Extending from the fiber receiving means through the fiber optic locator member is an optical fiber. The fiber is positioned within the locator member in such a way that it is in optical communication with the optical gate of the thyristor. Lastly, an anode member electrically and thermally adjoins both the anode conductive layer and the   base plate of the housing. The anode member is electrically insulating to allow for high voltage isolation of the module and thermally conducting to allow for heat dissipation.

Abstract: Telescopic antenna with integrated microphone of a device with RF receiving section and recorder. Modern radio-cassette recorders are, for example, capable of stereo in most cases and are equipped with two microphones at the front of the housing. Devices with up-market equipment are also provided with additional connection capabilities for external microphones. With the microphones integrated in the housing, the directional characteristic is disturbing and the achievable stereo effect is limited. It was the basic object of the invention to improve this situation. In accordance with the invention, a microphone is integrated in the head of the telescopic antenna. If two telescopic antennas with one microphone each are provided, it is possible, due to the mobility of the antenna, to achieve a better recording characteristic and a clear right-left separation for an optimised stereo effect and also to reduce drive noises in the recordings.

Abstract: A side pumped, fiber optic amplifier comprises an optical fiber (12), having a first refractive index, formed of a laser material, such as Nd:YAG. A jacket (14), which surrounds the optical fiber (12), has a second refractive index, lower than the first refractive index. This jacket (14) is cone shaped and tapers from a large end (16) to a small end (18). High power laser diodes are mounted on the large end (16) to produce collimated pump light to pump the optical fiber material. The cone shaped jacket (14) focuses this pump light to an interaction region at the small end (18), where the jacket material is quite thin, e.g. on the same order of magnitude as the diameter of the optical fiber (12). The focused light is absorbed by the optical fiber (12) in this interaction region, and causes an electronic population inversion in the laser fiber material. A signal propagating through the optical fiber (12) stimulates spontaneous emission from the optically excited laser material, thereby resulting in amplification of the signal.
