    摘要: Disclosed is a terminating circuit in a battery feed circuit of an electronic exchange system. The battery feed circuit comprises two transconductance amplifiers connected by a coupling capacitor, for supplying a direct current through a ring terminal and a tip terminal to a load. Each of the transconductance amplifiers comprises an operational amplifier; a resistor connected between the output end of the operational amplifier and the tip terminal or the ring terminal, and an impedance unit connected between the inverting input terminal of the operational amplifier and the output end. The impedance unit has an impedance determined in such a way that the required terminating impedance of the battery feed circuit when viewed from the tip terminal and the ring terminal is formed only by the internal elements including the impedance means and the resistor, whereby an external larger-size capacitance capacitor for matching becomes unnecessary.

    摘要: An active suspension apparatus using hydropneumatic springs is disclosed to control damping characteristics in accordance with the vibration state of the passenger compartment of a vehicle during travel. An absolute acceleration of the floor of the passenger's compartment is detected and is compared with a reference value to discriminate the actual vibration state of the passenger compartment. The openings of restrictors arranged between hydropneumatic spring chambers and actuators are controlled in accordance with the discrimination result. In order to accurately detect the vibration state, specific vibration components are extracted by band-pass filters from the absolute acceleration signal.

    摘要: To reduce or prevent effect of deterioration of communication quality caused from packet loss in a packet communication, a plurality of Packet Assembly Disassembly devices (PDAs) are installed at a first terminal equipment and at a second terminal equipment, and a packet communication is performed using one PDA in such plurality of PDAs. If the packet loss of received data in such packet communication is detected exceeding the predetermined value, a request is sent using another PDA to the first terminal equipment for transmitting the same data that above-stated one PDA is handling and the data transmitted at the request is received. On reception of the data at the request, sizes of the packet loss rate of received data with above-stated one PDA and of the packet loss rate of received data with above-stated another PDA are compared and the packet communication is continued selecting a system of which packet loss rate is smaller.

    摘要: In order to actualize a power feeding control apparatus and a charging system that are capable of efficiently charging plural storage batteries using a load-capacity controlled power source, the power feeding control apparatus 1 is configured so that a changeover control of the feeding of the alternating-current voltage to each charger will be performed monitoring the magnitude of the alternating current flowing in each of the plural chargers 4 to 6, therewith, the power feeding control apparatus performs the feeding changeover control comprising the steps of: feeding only to a predetermined one particular charger at the early stage of the start of charging, in which stage a large charging current flows into a storage battery; monitoring inflow current of the predetermined one particular charger; and switching power feeding to another charger to start feeding thereto when the inflow current reduces to the charging saturation current (a current still flowing even at the fully charged state).

    摘要: An automobile antenna including a high frequency signal processing unit provided near an antenna where the processing unit only tunes in a designated frequency band and amplifies it and further detects the amplified signal. The high frequency signal processing unit also adjusts the tuned frequency band at the high frequency signal processing unit based upon a tracking signal sent from an automobile receiver. Since the high frequency signal processing unit is provided adjacent to antennas, that is, near a glass antenna or mounted on an antenna mast, a loss which occur between the antenna and the receiver can be fully compensated for and noise interference can be avoided.
