摘要： PURPOSE:To make a time up to the reset of a microcomputer(MC) after the generation of an alarm constant by writing a voltage higher than the voltage at the reset which is stored in a memory by a fixed value in a memory, etc., as an alarm data and generating the alarm when supply voltage reaches the voltage value. CONSTITUTION:The digital value of an A/D conversion circuit 2 is written in the specific address of a memory 5. When the digital value changes with a decrease of the power supply voltage, the lowering current digital value is written in the memory 5. When the supply voltage is lowered gradually while the microcomputer, runs on a test program, and an MC 1 is reset, a digital value acquired by converting the voltage where resetting is made, is recorded in the memory 5. Contrarily, while an actual program, runs, the MC 1 monitors the drop of the supply voltage as a digital data. When the digital value is compared with a voltage value reset and the voltage exceeds the reset voltage by a fixed value, an alarm circuit 4 is operated.

摘要： PURPOSE:To receive and transmit an exact control data by encoding a sub signal from the transmission side by means of the ID cord of the transmitter through logic operation and decoding the received sub signal by means of the ID cord of a receiver through logic operation. CONSTITUTION:Before transmitting a data signal 16 an ID code and an XOR (exclusive-OR) are operated in a CPU to make process data 16a, and the signal 16 is coupled with a bit synchronizing signal 14, a frame synchronizing signal 15 and a parity signal 17, and is transmitted through a transmission circuit. Thus sub-signals can be received and transmitted during the transmission and reception of the same set without extending the mute time during telephone call, thereby the control data is exactly received and transmitted.

摘要： PURPOSE:To realize adequate quick charging which is free from overcharging and insufficient charging by using a timer for controlling the charging. CONSTITUTION:A timer makes addition in a rapid charging mode and subtraction during a charging stopping period. When the added value of the timer becomes lower than a certain value, the quick charging mode is started and, when the added value becomes higher than another certain set value, a low- speed charging mode is started. In addition, the timer performs addition or subtraction with a prescribed coefficient during a rapid charging period or charging stopping period.

摘要： PURPOSE:To prevent a illegal use by introducing a current parity number via an arithmetic means prior to the start of communication, comparing the parity number with a regular parity number stored in advance in a storage means and disabling the start of communication when both are dicordant. CONSTITUTION:A manufacture number storage means 3 stores a manufacture number specific to a portable telephone set and a parity number storage means 4 stores a regular parity number calculated from the manufacture number by a calculation in advance. An arithmetic means 3 reads the manufacture number from the means 3 and makes arithmetic operation. A comparison means 8 compares a parity number in the means 4 with a parity number from the current manufacture number calculated by the means 7 and issues the command of setting an inhibiting flag in a ROM when the both are different and sets no flag when they are identical. A key locking means 9 checks an inhibiting flag area in the ROM and disables the start of communication of the portable telephone set when the flag is set. An alerting means 11 is activated by the command of setting a flag from the means 8 to activate a display device 10, thereby displaying the disabled communication of the portable telephone set.

摘要： PURPOSE:To attain the reception with excellent sensitivity by fitting an equipment main body into a recessed part of a dashboard so as to attain induction coupling between a 1st antenna in the equipment main body and a 2nd antenna in the dashboard. CONSTITUTION:When a pager 2 is installed in a cabin, it is fitted to a recessed part 3 of a dashboard 1 and when a radio wave is received by an external antenna 6 in this state, the radio wave is led to an antenna 4. Then the antenna 4 and the antenna 7 built in the pager 2 are subject to inductive coupling and a received radio wave is led to a reception circuit in the pager 2. When an individual code (ID code) possessed by the pager itself exists in the received radio wave, the pager 2 informs the reception of the signal by a light emitting diode LED and a buzzer 6. When a numerical data such as a telephone number is sent after the ID code, the number is displayed on a display device LCD. Thus, the pager 2 utilizes an external antenna 9 to obtain excellent reception sensitivity.

摘要： PURPOSE:To attain correct evaluation of data demodulation capability of a reception equipment in the state close to practical use, and to easily solve a problem of the demodulation capability by providing a pseudo random code generator and a jitter modulation controller or the like. CONSTITUTION:A data generator 1 generates a digital data to be sent and a PN code generator 2 generates a pseudo random code being a test code (M series code or longest series code in terms of PN code). Moreover, a jitter modulation controller 3 adds a P code to a data from the generator 1 to provide jitter to an equipment 4 to be measured. Furthermore, since it is possible to add frequency control externally to the generator 2 and the equipment 4 is equivalent to a data demodulator, the demodulation capability is evaluated numerically by measuring the demodulation output. Thus, the data demodulation capability of a reception equipment is correctly evaluated in the state close to actual use, and a problem of the demodulation capability is easily solved.

摘要： PURPOSE:To increase the tape speed in steps, when searching operation is started, by constituting a high speed search servo circuit with an integrating circuit for taking in a high speed search control signal, an A/D converter, a multiplexer, a FV converter, and the like. CONSTITUTION:Upon provision of a search operation command to a microcomputer 9, output from a frequency generator(FG) signal amplifier 5 is subjected to frequency division in eight steps through a binary counter 6 and fed to a multiplexer 4. The multiplexer 4 selects the divided frequency in the order of frequency. A FV converter 7 outputs a signal voltage inverted into a low voltage for high frequency and feeds the signal voltage sequentially to an amplifier 8 thus driving a capstan motor 11 through a drive amplifier 10. By such arrangement, speed can be increased sequentially and application of excessive force onto the tape can be prevented.

摘要： PURPOSE:To eliminate a aliasing noise by adding an analog signal including an original signal from a D/A converter and an aliasing noise component of the same output via a high pass filter in opposite phase to each other in an operational amplifier. CONSTITUTION:A signal output subject to reproduction processing at a signal processing circuit 1 is converted into an analog signal at a D/A converter 2 and its output included aliasing noise. Since the noise component passes through a high pass filter 3, a noise component is detected from the output of the filter 3, and the output of the filter 3 is fed to an operational amplifier 4 in an opposite phase. On the other hand, an analog signal is fed to a noninverting input terminal of the operational amplifier 4 in a normal phase. Thus, the aliasing noise component is subtracted in the operational amplifier 4 and the original signal with aliasing noise eliminated therefrom is obtained at the output of the operational amplifier 4.
