摘要： PROBLEM TO BE SOLVED: To provide a vehicle search system by which a user can easily reach a target vehicle even when parked at a huge parking lot. SOLUTION: When vehicle activation instruction is executed by a switch button 25, after remote control direction of a remote control 20 is detected by a geomagnetic sensor 22 and a transfer request for the vehicle direction, which the target vehicle faces, is transmitted by a bidirectional receiver/transmitter 21, the vehicle direction is acquired, circumference of the vehicle is divided into a plurality of areas with the vehicle direction as the basis, the area radio wave transmitted from the vehicle toward each of the area directions is received by an area radio wave receiver 26, and the area radio wave with the highest receiving level is detected by a level detection circuit 26a. Thus, among a plurality of the areas divided with the vehicle direction acquired as the basis, by discriminating that the direction of the remote control direction faces either directions of the areas and the remote control 20 exists in either areas, the parking direction of the vehicle is identified and displayed on a screen of a display part 23.

摘要： PROBLEM TO BE SOLVED: To reduce the processing cost of a diode formed on the same chip as a switching element so as to detect the temperature of the switching element. SOLUTION: An IGBT Q1 drives a load L1 by a PWM modulation signal. A transistor Q5 is connected between a gate of the IGBT Q1 and the ground. A cathode of the diode D4 formed on the same chip as the IGBT Q1 is connected with the gate on the chip while an anode of the diode D4 is connected with the transistor Q10. The transistor Q10 comprises a constant current source together with the transistor Q8, Q9. The IGBT Q1 is turned off, and the transistor Q5 is turned on when detecting the temperature. Then, a bias current flows to the diode D4 from the constant current source, and the forward voltage enables the detection of the temperature of the IGBT Q1. Since the end of the diode D4 is connected with the IGBT Q1 on the chip, the number of wires to be drawn out of the chip to the outside becomes one, which reduces the processing cost.

摘要： PROBLEM TO BE SOLVED: To provide a high-reliability small-size semiconductor integrated circuit which executes the short-circuited load diagnosis when the temp. rises, and operates the system, without stopping the control of a drive circuit below the operable upper limit temp. of the drive circuit. SOLUTION: When the temp. of a system-on Si chip 100 rises over the operable upper limit temp. of a CPU 1 at a usual frequency, an overheat detector 6 generates an alarm signal to lower the clock frequency of an oscillator circuit 2. The CPU 1 does the short-circuited load diagnosis to light an alarm lamp 14 and cut off a power relay 16 if the load is short-circuited. It further executes required limited basic controls for operating the system to continue operating a drive circuit 4. If the chip temp. more rises over the operable upper limit temp. of the drive circuit 4, an overheat detector circuit 7 outputs an alarm signal and CPU 1 locks the drive circuit 4 to be off.

摘要： PURPOSE:To transmit a response properly corresponding to the actual load state to a master station. CONSTITUTION:The multiplex communication system sending and receiving communication data through a communication line 101 between a plurarity of slave stations and a master station is provided with a prohibition means (a communication control part 200 and an AND circuit 201) prohibiting the take-in of the input data in a load state in an input register 108 from the point when an address coincidence discrimination circuit 105 detects the coincidence of address in slave units to the end of transmission of each time. Accordingly, as the take-in of the input data in the undefined area period in the load state is prohibited and the data is taken in after the load state is stabilized, a response properly corresponding to the actual load state can be sent to the master station.

摘要： PURPOSE:To reduce the number of components of an output circuit and to facilitate circuit integration by changing over two switching means with an external control signal to bring two P and N-channel MOS transistors(TRs) into a high impedance state and to act them like an inverter. CONSTITUTION:When a signal is not outputted to a transmission line 140 via the output buffer circuit 120, a switch means 123 connects the gate of a P- channel MOS TR P1 to a power supply with a control signal 102. Then a switching means 124 connects the gate of an N-channel MOS TR N1 to ground. Thus, the TRs P1, N1 are turned off to be reached to a high impedance state independently of the signal from a signal line 129. When the signal is outputted to the transmission line 140 via the output buffer circuit 120, the switching means 123, 124 connect each gate of the TRs P1, N1 to the signal line 129 and an output circuit 122 acts like an inverter circuit with a mirror capacitor 121.

摘要： PURPOSE:To detect a fault in a transmission line quickly by discriminating separately a signal change indicating whether or not a transmission data is present on 1st and 2nd transmission lines at every bit by 1st and 2nd carrier sensing means and applying arithmetic processing to the discriminated signal. CONSTITUTION:When a fault such as a 1st transmission line 1 in short-circuit with ground takes place, only the signal change of a transmission data A2 from a 2nd transmission line 2 is inputted to a fault detector 400. A carrier sensing means 420 outputs a carrier sensing signal a2 being logic '1' to indicate that the abnormality is present on the 1st transmission line 1 and that the 2nd transmission line 2 is normal. Moreover, when any of communication equipments does not send transmission data A1, A2, carrier sensing signals a1, a2 outputted by the carrier sensing means 410, 420 are both logic '0' and it indicates that both 1st and 2nd transmission lines 1, 2 are normal.

摘要： PURPOSE:To relieve the load of the software at a master station by sending a dummy signal representing the normal state to a slave station via a communication line when no communication of the master station with the slave station is implemented and allowing the slave station to discriminate it that the master station and the communication line are normal with the signal received from the master station. CONSTITUTION:A master station 10 connects to plural slave stations 20 via a serial bus 5 being a communication line and the master station 10 is able to communicate with each of the slave stations 20. A dummy signal generating circuit 10f provided to the master station 10 sends a dummy signal representing the normal state of the master station 10 to the slave stations 20 via a communication line 5 when the master station 10 makes no communication with the slave stations 20, each of the slave stations 20 receives the dummy signal sent from the master station 10 to discriminate by the dummy signal it that the master station 10 and the communication line 5 are normal. Thus, the load of the software of the master station 10 is relieved to attain the efficiency.
