    • A hands-free telephone for use on a vehicle includes a handset incorporating a radio section therein and a hands-free adapter incorporating a hands-free telephone unit therein. To prevent howling, the telephone includes two variable attenuators, or variolossers, each for changing the level of respective ones of a receive and a transmit signal to be applied to a speaker of the hands-free telephone unit and the radio section, respectively, so as to maintain the two levels in a predetermined relation. The telephone also includes in the radio section a variable resistor which may adjust the volume of voice signal to be delivered through an earpiece within the radio section which adjusts the volume of voice signal to be delivered through the speaker. The level-adjusted voice signal to be delivered through the speaker is controlled in level by a third variable attenuator simultaneously with the above-mentioned variable attenuators.

    • In a charge device having a storage cell terminal (11) to be connected to a storage cell (12) to be charged, a trickle charge terminal (13) for receiving a trickle charge voltage, and a boost charge terminal (14) connected to the storage cell terminal for receiving a boost charge voltage and including a constant current circuit (16) for causing a constant current to flow from the trickle charge terminal to the storage cell terminal, a boost charge detector detects the boost charge voltage to produce a boost charge signal when the boost charge terminal is supplied with the boost charge voltage. An interrrupting circuit interrupts the constant current when the boost charge detector circuit produces the boost charge signal. The constant current circuit may comprise a transistor (161) having a base electrode supplied with the trickle charge voltage to produce the constant current. In this event, the interrupting circuit is a conductor (191) connected between the boost charge detector and the base electrode of the transistor (161).

    • A charging circuit charges a nickel-cadmium battery by means of a constant current source. A resistor, diodes and a tantalum capacitor are connected between an output terminal of the charging circuit and a ground potential. A junction between the capacitor and the diode is connected to one input terminal and an output terminal of a comparator and to the output terminal of the charging circuit. The other input terminal of the comparator is supplied with a reference potential. An output signal having a period which depends on a voltage of the battery is generated at the output terminal. The diodes compensate for a variation of the period of the output signal caused by temperature dependent capacitance change of the capacitor.

    • An image signal coding apparatus includes reference and coding line change point detection circuits, reference line shift registers, a coding line shift register, a symbol detection circuit, coding and reference line ROM tables, and a code determination circuit. The coding line change point detection circuit receives a serial reference line image signal in synchronism with a serial coding line image signal. The reference line shift registers receive serial change point data in the reference line image signal and output parallel reference line change point data. The coding line shift register receives serial change point data in the coding line image signal and outputs parallel coding line change point data. The symbol detection circuit monitors output states of the reference and coding line shift registers. A run length counter counts the number of pixels between the change points in the coding line image signal. The ROM tables cooperate with the code determination circuit to code the coding line image signal in response to outputs from the symbol detection circuit and the run length counter.
