    摘要: Controlled by a signal level produced by a microphone (12), a noise suppressing circuit (25) supplies a first attenuator (16) with a local level which is equal to the signal level and is suppressed to a predetermined output level when the signal level is lower and higher than a predetermined input level. Cooperating with a drive level produced by a second attenuator (17) to drive a loudspeaker (13), the local level makes a comparator unit (21-23) produce a control signal for making the first attenuator give smaller and greater amounts of attenuation to the signal level with the drive level rendered by the second attenuator low and high when positive and negative values are had, respectively, by an input difference equal to the local level less the drive level. Preferably, the local level is suppressed by a level difference had by the signal level above the predetermined input level.

    摘要: 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.

    摘要: A power supply switching apparatus for electronic equipment including a first control circuit connected to a battery. The first control circuit monitors a power supply voltage of the battery to output a first control signal when the power supply voltage of the battery is lower than a first predetermined voltage. The first control circuit also outputs a second control signal when the power supply voltage of the battery is higher than a second predetermined voltage. A second control circuit monitors whether power is supplied from an external power supply to the electronic equipment, to generate a third control signal when the power is not supplied from the external power supply. The second control circuit generates the third control signal regardless of whether the second control signal is present, when power is supllied from the external power supply. A switching circiut section supplies power from the battery to the internal circuit when the first and third control signals are not present. The switching circuit section disconnects the battery from the internal circuit in response to the first or third control signal.

    摘要: If, in a clock generator according to the present invention, the first clock is switched to the second clock with a lower frequency, the frequency count circuit counts the frequency of the second clock with using the first clock as reference. The clock switching control means judges whether the frequency of the second clock is stable or not based on the count result from said frequency count circuit and, if it is stable, switches the switching means for clock switching to the second clock.

    摘要: An adapter 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 is used with the adapter, the adapter is switched on and off by a power switch 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 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.

    摘要: When the number of fingers assigned to a branch signal is smaller than the aimed number and there is a path to be added, the search is performed for an unused finger, firstly, and for one of fingers, the number of which is larger than the aimed number and which are assigned to the branch signal, which has the lowest receiving signal level, secondly. When the aimed number of fingers is satisfied and there is a path to be added, an unused finger is used if any and, when there is only an effective finger, the number of fingers assigned to a branch signal is not increased.

    摘要: A cellular telephone includes a speed dialing memory and a current location memory. International access codes respectively identified by corresponding country codes are stored in an access code memory. An indication of the current location of the telephone is stored in the current location memory. A destination address number is retrieved from the speed dialing memory in response to entry of a speed dialing code through a keypad when a call is originated. The country code of the retrieved number is compared with the stored location indication to detect a match or a mismatch. A first decision is made that the originated call is an International call if a mismatch is detected, or a second decision is made that the cell is domestic if a match is detected. In response to the first decision, an international access code is retrieved from the access code memory corresponding to the stored current location indication and appended to the retrieved address number, and in response to the second decision, the country code of the retrieved address number is replaced with a digit "0".
