Abstract:
The invention relates to a method of producing an electrical contact (10) on a section (12) of a surface of a semiconductor diode (1), notably a thin-film diode. According to said method a metal layer (113) is applied to at least a part of the surface section (12) and the contact (10) is produced by thickening the metal layer (113) by electroplating.
Abstract:
The invention relates to a method and a device for sorting letters and packages into delivery route order using a first part of the address which gives the destination and a second part which contains the addressee and his/her postal address at the destination. The second parts of the destination addresses are read automatically using directories which only contain the possible addressees at the particular destination and their postal addresses, in order to interpret the addresses. In the event that the second part of an address is not clearly automatically read, at least this second part of the address is video-coded at the destination.
Abstract:
The invention relates to an HF plug-and-socket device (1) that includes a contact device arranged inside a casing (2) having a coding device (3). Coding of the HF plug-and-socket device (1) can be accomplished by means of the coding device (3) provided in the casing so that no confusions arise when several HF plug-and-socket devices are connected. A permanently safe HF connection is achieved by means of a locking device (4) embodied in the casing, whereby locking can be carried out in a particularly easy manner through a locking device (4) embodied in the form of snap-on components.
Abstract:
The invention relates to an overcurrent circuit-breaker, especially a generator power circuit-breaker, comprising a three-pole interrupter unit which switches the nominal current and the short-circuit current. Each of three-pole interrupter units are equipped with a separate actuating device. The three-pole interrupter unit (DUE) is formed by at least one power-circuit breaker of the first type (LSN) which carries the nominal current, and by a power-circuit breaker of the second type (LSK) which switches the short-circuit current and the nominal current. The power-circuit breakers of the first type (LSN) and the power-circuit breaker of the second type (LSK) comprise a common actuating device (ATE) having a rigid coupling. In addition, the power-circuit breakers of the first type (LSN) and the power-circuit breaker of the second type (LSK) have a different or identical contact travel (KH). Such overcurrent circuit-breakers can be used in the area of power supply technology.
Abstract:
Disclosed is a display device for circuit breaker installations, especially for air and gas isolated medium voltage switchgears comprising the operational features ôcircuit breakö, ôdisconnectö and ôgroundingö. The display device is formed by a diagrammatic representation (SB) covering nearly the entire surface on a protection panel (BA) closing the front contour of the circuit-breaker installation, wherein the circuit-breaker influences a circuit-breaker position display device (AL), the disconnector influences a disconnection position display device (AT), the cable grounder influences a cable grounding position display device (KA) and the bus grounding switch influences a bus grounding switch position display device (SA). Such display devices are used to monitor the operation of switch-breaking installation in energy supply and distribution.
Abstract:
The invention relates to a method and a device for digital data radiotransmission between a fixed station (1) and at least one mobile station (2, 3) at one or several carrier frequencies (F1, F2 ...), wherein the data is transmitted in several time slots (Z1, Z2 ...) according to the time-multiplex technique. A specific amount of time is required to change from one carrier frequency to another carrier frequency using a slow-hopping HF module. The data is transmitted in an active followed by an inactive time slot during which no data is transmitted and which is sufficient for the HF module to program the frequency for the following active time slot. According to the invention, an inactive time slot is shorter than an active time slot.
Abstract:
The invention relates to a mobile radiotelephone for radiotransmission in time multiplex frames with alternating active time slots (Z1) in which data is transmitted and inactive time slots (Z2) in which no data is transmitted. The duration of the active time slots is twice that of the inactive time slots. The mobile radiotelephone (1, 2) has a burst mode controller (13) which converts the time multiplex frame structure of transmission and a clock input device (18) which clocks the burst mode controller (13). During inactive time slots (Z2), the clock pulse rate set by the clock input device (18) in the burst mode controller (13) is two times greater than during active time slots (Z1).
Abstract:
The invention relates to a radio interface for a small wireless installation in the 2.4 GHz ISM band. The invention provides a transmission system comprising a fixed station (1) and at least one mobile station (2, 3), wherein the fixed station (1) and the mobile station (2) have devices (HF modules 4, 5) for transmitting data in time slots according to frequency division multiple access (FDMA), time division multiple access (TDMA) and time division duplex (TDD). The data is modulated to a carrier frequency (fx) in a GMSK modulation method as per DECT standard. The HF modules (4, 5) in the fixed station (1) or mobile station (2) are configured in such a way that the carrier frequency (fx) is modified after a given time period which can, for instance, correspond to the duration of a time slot or a transmission frame. A transmission frame contains 16 time slots.
Abstract:
The invention relates to an electronic component (1) in which a standard feeder cable mounting frame (2) is used, whose island (4) is designed to accommodate an integrated switch circuit (1) which is dimensionally adapted to the base surface of said integrated switch circuit (1) in order to minimize and prevent housing deformations.
