摘要： PROBLEM TO BE SOLVED: To provide a multiplex communication unit that can accurately detect a communication fault without the need for adjustment/revision of a circuit and a program of each of slave stations even in the cast that a new slave station is extended in the multiplex communication unit where a master station and the slave stations make communication with each other in a predetermined sequence. SOLUTION: A reception circuit 27 detects whether or not a slave station (1) normally receives communication from the master station 11, and in the case that a permission circuit 49 continuously detects that the slave station (1) normally receives the communication from the master station 11 at a start, a buffer 55 stores a communication interval from the master station 11 to the slave station (1), the slave station (1) decides a fault discrimination time on the basis of this communication interval. In the case that the consecutive communication interval from the master station 11 to the slave station (1) is longer than the fault discrimination time after this decision, a discrimination circuit 59 discriminates the occurrence of a communication fault and outputs a fail-safe signal 63 to a fail-safe circuit 61 and the reception circuit 27.

摘要： PROBLEM TO BE SOLVED: To provide a multiplex communication system capable of reducing a communication format necessary to input output setting and quickly starting a device operation when the device is started. SOLUTION: A master station unit 101 transmits input output setting data to a slave station unit 102 through a communication line 105. The input output setting data consists of an output setting frame which has a bit width equal to the number of output ports and is composed of codes specifying either of two available modes, an input setting frame which has a bit width equal to the number of input ports and is composed of codes specifying either of two available modes and a communication pause period provided between the output and input setting frames. The slave station unit having received the input output setting data defines input-output ports of the bit width of the output setting frame as output ports among input-output ports, defines input output ports of the bit width of the input setting frame as input ports and decides either of two modes existing in inputs and output for every bit in accordance with the content of the output and input setting frames.

摘要： PROBLEM TO BE SOLVED: To provide a power converter for detecting an abnormality in a smoothing capacitor without applying a high voltage to a main circuit, and preventing thermal effects on damaged regions and peripheral components. SOLUTION: When a motor driver 100 is activated, a controller 180 turns off a relay 150 and turns on a relay 161. A voltage lower than an output from a battery 140 divided by resistors 162, 163 is applied between input terminals 111, 112 of an inverter 110. The controller 180 detects a voltage across the smoothing capacitor 130 by a voltage monitor 170, and detects the existence of the abnormality in the smoothing capacitor 130 by checking whether the smoothing capacitor 130 is charged within a predetermined time. If there is no abnormality in the smoothing capacitor 130, the relay 161 is turned off, the relay 150 is turned on, the output from the battery 140 is directly applied to the inverter 110, and a desired motor driving signal is generated.

摘要： PROBLEM TO BE SOLVED: To prevent a driving element from breaking by an overcurent and reliably suppress the surge voltage in turn-off. SOLUTION: The protector monitors a fine sense current which is proportional to a drive current (Ic), flowing in an IGBT Q1 being a drive element enough to turn on a transistor Q1 to draw gate charges into ground when an overcurrent flows, thereby lowering the driving current to protect the IGBT Q1; whereas, when the TGBT Q1 is turned off, it jumps up to a sense current Is sufficient to turn on the transistor Q2, the voltage across a capacitor C1 is sufficient to block the gate charges from being pulled out from the transistor Q2, but the charges are pulled out gradually through a resistor R3, to suppress the surge voltage from generating. The transistor Q2 discharges only the charges in the capacitor C1 with a diode D1 which acts to block charge from migrating from the capacitor to the gate.

摘要： PURPOSE: To secure high responsiveness even when resolution requested by a control unit is increased or the number of cells is increased. CONSTITUTION: The control unit 101 sends out a pulse string provided with two kinds of amplitude to a communication line 103 by superimposing an address or a requested data signal on a clock signal. In a sensor unit 102, each component of clock and data can be obtained by a clock/data separation circuit 109, and it is decoded by a decoder 110. When a received address coincides with its own address and a comparator 113 outputs an address coincidence signal, an output control counter 111 operates a timing output circuit 114 at a timing in which no signal exists on the communication line, and the analog output of a sensor 118 is sent out to the communication line. In this way, the control unit can obtain the output value of the sensor from pulse amplitude, and a sensor signal is transmitted in a comparatively small communication frame regardless of the resolution.

摘要： PURPOSE:To transmit serial data by allowing a transmission controller not having an oscillating source to superimpose data onto a clock signal from a transmission controller having an oscillation source and taking the operating timing with the clock signal. CONSTITUTION:An oscillating source 11 is provided to only a master station 10 and an original oscillating signal is frequencydivided into a prescribed frequency signal by a frequency divider circuit 12 to generate a clock signal and a transmission reception circuit 13 sends/receives a data signal and provides an output of the clock signal to a transmission line 20. On the other hand, a transmission reception circuit 31 of a slave set 30 connecting to the transmission lien 20 and not having any oscillating source transmits data serially while superimposing the data onto the received clock signal. Then a clock extract section 32 in the slave station 30 extracts the clock signal from the received signal comprising superimppsed clock and data signals and all the processing operations are implemented for the slave station 30 by using the extracted clock signal. Thus, the semi-duplex serial data transmission is conducted by having only to provide the oscillating source to one station on a network.

A change rate control means changes and sets a time change rate of a collector voltage Vce of the IGBT (Q1) from a high speed change rate immediately after turn-off to a predetermined change rate which at least uses respective impedance values of the capacitor (C2) and the gate resistor (R3), and is determined. A capacitor (C1) and a base resistor (R1) are connected in parallel as a delay means which delays an operation start time point of the change rate control means to a predetermined value determined beforehand which is in the vicinity of an operation threshold voltage of a base voltage of the PNP transistor (Q3).
