Abstract: An adapter (16) for mounting a portable telephone on a vehicle allows either one of a simple handset and a multi-function handset to be used therewith as desired. The adapter does not need a power switch and associated circuitry and, therefore, reduces the overall weight and size of a portable telephone system. When a multi-function handset (14) is used with the adapter, the adapter is switched on and off by a power switch (14a) which is provided on the handset. When a simple handset is used with the adapter, the adapter is switched on and off by an ignition switch (34) which is provided on the vehicle. Further, the adapter promotes easy and convenient use of a handset because it automatically adapts itself to both of a multi-function handset and a simple handset.

Abstract: A light emitting element drive circuit which has high operation speed, low current consumption and provides an optical output signal with minimum distortion. An inverted input signal is applied to a second transistor which drives a differentiating circuit. The differentiating circuit drives a third transistor which provides a current path for discharging the light emitting element. The light emitting element discharges when the input signal falls. The input of the differentiating circuit and the input of the light emitting element drive circuit are isolated to prevent "back gating" distortion of the optical signal.

Abstract: 2.1 In data transmissions in communication switching systems, the frequency of seizure of the central processor during the input procedures is to be greatly reduced. The input procedures or input configurations are to be converted into data records which are in each case optimum for a data terminal, in such a manner that no program changes in peripheral devices are required for adapting these to already existing structures. 2.2 When a traffic route provided for data connections is selected, initially only one connection is established to a processing device. The identity and the characteristics of a calling subscriber terminal are transmitted by the switching system to the device and it receives the dialling information emitted from there and the input information. In the processing device, various memories are selected for checking the overall input information items for plausibility and completeness. It is only after this check is positively concluded, that a data link to a data terminal is set up and a matching output data record is transmitted. 2.3 The method has the result that the central processor does not need to be seized with each individual data input. In addition, newly added input terminals and data terminals can be matched to existing structures without having to carry out modifications in these peripheral devices. <IMAGE>

Abstract: 2.1 The invention is based on the object of specifying transformer circuits which, with types which differ little, provides a pulse number of 24 when operating two transmitters on one network and whose windings require no additional insulation on one limb. 2.2. According to the invention, the object is achieved in that a delta circuit on each primary of the transformer is integrated into a star circuit and a specific phase rotation is achieved depending on the size of the delta circuit. By selecting a specific rotation angle, it is then possible according to the invention to use the same two transformer types for a second transmitter as for the first transmitter and, by exchanging two supply current conductors at the transformer input, to rotate the phase such that a 24-pulse circuit is obtained overall. The phase rotation can be set such that it leads to a small current distortion factor. 2.3. The invention is used as a converter circuit, in particular for high-power transmitters, there being two transformers per transmitter, each having a three-phase winding arrangement on the primary and in each case at least one three-phase winding arrangement on the secondary, and a bridge rectifier with a filter element being connected downstream of each winding arrangement on the secondary, and the voltages of the two winding arrangements on the primary being phase-shifted with respect to one another. <IMAGE>

Abstract: A decision feedback equalizer for equalizing a received analog baseband signal (l) has a gain control circuit (ll) which compresses the amplitude of the baseband signal (l) to l/K (K ≧ l). The compressed signal is converted to a digital signal by an analog-to-digital converter (l2). A decision feedback equalizer section (l0l) has a feedforward equalizer (20l) to which the digital signal is applied, a feedback equalizer (202), and an adder (l3) for adding the outputs of the feedforward and feedback equalizers. A postprocessor (l5) discriminates the adder output (Sl') which has been multiplied by K to thereby output a received data signal (d) and a discrimination error signal (e). An expansive decision circuit (l04) expands the adder output by L times (L > l), discriminates the expanded signal, and delivers the result of discrimination to the feedback equalizer (202). A control signal generator (l02) feeds tap coefficients to the feedforward and feedback equalizers.

Abstract: A head base for fixing a head chip which consists of magnetic substances is formed by using conductive resin materials. By this formation, a plurality of discrete head bases can be manufactured at a time and also a plurality of head bases can be molded as an unit. Also, since the head base can be molded by burying the head chip in the head base, an adhesive process of the head chip can be omitted. Further, when a plurality of head chips are buried in the head base, precise positions in the horizontal and height directions can be determined by using a die. Also, the electrification of the head chip can be easily prevented. In addition, because the reduction of the head weight is intended, a dummy base for balancing is not needed when the head bases are disposed on a rotary drum, or a dummy base can be simultaneously molded when the base is molded. 
     Furthermore, the surface roughness of the head chip bonding portion produced on the head base is made rougher than the other surface portions, so that chip bonding strength can be made stronger.
