摘要： This optical receiving device for discriminating and recovering a data signal, which results from converting an optical signal input through a dispersion equalizer into an electrical signal and amplifying it to a pre-determined amplitude, by using a clock and data recovery circuit for discriminating a data signal at the decision point controlled to achieve the optimum position controls the dispersion characteristics of a dispersion equalizer so that the error count in the recovered data signal by using a clock and data recovery circuit will be minimized by controlling the eye pattern of the data signal which has been amplified to a pre-determined amplitude.

摘要： At a base station 2, a CDMA received signal coming in through an antenna 4 is fed to a radio frequency unit (RFU) or high frequency unit 6. The RFU 6 demodulates a baseband signal BB from a signal RF and delivers the signal BB to an analog-to-digital converter (A/D) 8. The resulting digital signal output from the A/D 8 is input to a hybrid interference canceller (HIC) 12 as a received signal Rx Data 10. The HIC 12 divides users into two groups and assigns one combination of a parallel interference canceller and a serial interference canceller to each group. The HIC 12 cancels interference contained in the received signal Rx Data 10 for thereby estimating symbols particular to a plurality of users.

摘要： A method of manufacturing a noise-cut filter having distributed inductances and distributed capacitances is produced wherein conductive spiral coil patterns are formed on the opposite surfaces of a dielectric sheet, such that the spiral coil patterns are aligned with each other in a direction perpendicular to the plane of the dielectric sheet, and a main circuit pattern is constructed by bonding a main circuit conductor to the spiral coil pattern formed on one of the opposite surfaces of the dielectric sheet. The main circuit conductor is formed by stamping with a punch press so that the conductor has a cross sectional area large enough to allow the passage of current of a main circuit, and has substantially the same shape as the spiral coil pattern. Further, a grounding wire is bonded to the spiral coil pattern formed on the other surface of the dielectric sheet, so that the grounding wire leads the current involving noises which flows from the main circuit pattern into the spiral coil pattern via the dielectric sheet, to a ground terminal.

摘要： A DC-DC converter includes a primary side circuit for allowing a switching device to perform on/off operations to output energy in a primary coil of a transformer to a secondary coil. A secondary side circuit rectifies and smooths a voltage outputted from the secondary coil so as to output a DC-DC voltage. A voltage-detecting circuit rectifies and smooths a voltage outputted from a voltage-detecting coil provided in the transformer so as to output the voltage as a detected voltage corresponding to a voltage to be outputted from the secondary side circuit. A control circuit applies to the switching device a pulse control signal used for controlling on/off operation of the switching device according to the voltage outputted from the voltage-detecting circuit. A primary side current-detecting circuit converts a working current in the primary side circuit, the working current corresponding to a current in the secondary side circuit, for performing detection thereof, and for superposing the thus detected voltage corresponding to the working current with the detected voltage outputted from the voltage-detecting circuit so as to compensate for an amount of variation of an output voltage of the secondary side circuit. The variation is attributed to a variation of the working current in the secondary side circuit. A voltage determined by the superposed voltage is applied to the control circuit.

摘要： An overcurrent protection circuit provided for a switching power supply has a current detector, voltage superposition device, and circuit for reducing a driving pulse. The current detector detects a circuit current in the switching power supply and converts it to a voltage. The voltage superposition device generates a constant voltage and superposes the voltage onto the detected voltage converted by the current detector. The detected voltage onto which the constant voltage has been superposed is applied between the base and the emitter of a transistor which functions as the circuit for reducing the driving pulse. If an overcurrent flows through the switching power supply, the transistor is turned on and a current flows into the transistor. As a result, a voltage applied to a maximum-duty-cycle setting terminal of a PWM IC provided for the switching power supply and used for pulse-width-modulation control of a switch device is reduced, and the overcurrent is suppressed.

摘要： A portable radio communication device has an antenna which can be extended for use and retracted for storage, and can transmit a signal at the same level of electric energy when the antenna is stored as when the antenna is extended. When the antenna is retracted and stored, the stored condition is detected by a detecting switch. In response to a detected signal from the detecting switch, a transmission output controller produces an increased transmission output control signal to increase the level of electric energy of the signal to be transmitted which is higher than a normal level of electric energy of signals transmitted from the antenna. When the increased transmission output control signal is generated, a power amplifier amplifies a signal to be transmitted which is supplied from a transmission signal generator, and supplies the amplified signal to the antenna. Therefore, even when the antenna is stored, it can radiate the signal at the same level of electric energy as when the antenna is extended. The antenna comprises an antenna which operates as a loaded antenna when it is extended and as a helical antenna when it is stored.

摘要： A variable transmission power type transmitter comprises a transmission amplifier, a detecting circuit for detection of a transmission wave signal from the transmission amplifier, an automatic power control circuit for automatic control of the transmission power of the transmitter amplifier depending on the difference between a set value and a detected output of the detecting circuit, a set point providing circuit for generating set values and for selecting one of the set values to be supplied to the automatic power control circuit, and a transmission interruption detecting circuit for detecting existence or absence of the transmission wave signal by comparing the detected output of the detecting circuit with a reference value. The reference value is automatically generated from one of the set values in the set point providing circuit. Therefore, a variable resistor for adjusting the reference value and a adjustment process of the reference value are not required.

Also provided is a bake hardenable, surface treated aluminum alloy sheet having improved formability, an elongation of at least 25%, a sliding frictional resistance of up to 0.13 and minimized surface pressure dependency of sliding frictional resistance, comprising a bake hardenable aluminum alloy substrate containing Mg and Si in an amount of at least 0.4 wt % calculated as Mg.sub.2 Si and a Fe rich plating layer on a surface thereof in coating weight of 1 to 50 g/m.sup.2. By forming a zincate layer as an undercoat below the Fe rich plating layer, the plating adhesion is further improved. The preferred Fe rich plating layer is a Fe-Zn alloy plating layer containing 20 to 80 wt % of Zn for corrosion resistance improvement. A Fe-Zn alloy plating layer containing 30 to 40 wt % of Zn meets both formability and corrosion resistance.
