An inverter control device includes a voltage detector, a target value calculation section, an inverter control section, an abnormality detector and a voltage clamp unit. The target value calculation section calculates target value of an alternating current output from the inverter based on a detection voltage detected by the voltage detector. The inverter control section generates a control signal for a switching element of the inverter based on the detection voltage and the target value to control the inverter. The abnormality detector detects an abnormality in the voltage detector. The voltage clamp unit holds the detection voltage for calculating the target value at a first assured voltage determined based on a lower limit area of an assured voltage range that assures an operation of the inverter and holds the detection voltage for generating the control signal at a second (higher) assured voltage upon detecting the abnormality in the voltage detector.

Powders of respective metal elements (Mn,Co) constituting a transition metal oxide (MnCo2O4) having a spinel type crystal structure are used as a starting material. A paste containing the mixture of the powders is interposed between an air electrode and an interconnector, and with this state, a sintering is performed, whereby a bonding agent according to the present invention can be obtained. This bonding agent has a “co-continuous structure”. In the “co-continuous structure”, a thickness of an arm portion that links many base portions to one another is 0.3 to 2.5 μm. The bonding agent includes a spherical particle in which plural crystal faces are exposed to the surface, the particle having a side with a length of 1 μm or more, among the plural sides constituting the outline of the crystal face. The diameter of the particle is 5 to 80 μm.

An electric current supply control apparatus for a glow plug, and glow plug and the electric current supply control apparatus connected to the glow plug. In a transition state in which the load acting on an engine increases such as at the time of acceleration (S14: YES), an instruction signal which instructs increasing of an EGR amount is transmitted to an ECU (S18). Further, electric current is supplied to a heat generation resistor of a glow plug through resistance PI control (S20), whereby the temperature of the heat generation resistor is stably maintained at a target temperature, and stability of combustion is enhanced. Thus, even at the time of acceleration, generation of NOX can be suppressed effectively by increasing the EGR amount without lowering the engine output.

A risk evaluation support device is used for a safety network which serves to cause an output device to make a controlled device operable based on a detection signal outputted from an input device when the input device detects a safety condition. The support device creates a parameter setting table for correlating a danger source with the input and output devices and a PLC for risk evaluation based on configuration data of the safety network obtained through a communication part and device data on devices obtained from a component database. Operating data for the safety network are obtained according to conditions provided by the parameter setting table and a current risk evaluation value for the danger source is calculated based on the obtained operating data. The calculated risk evaluation value is outputted to a display part.
