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 a target value of an alternating current output from the inverter based on a detection voltage. The inverter control section controls a switching element of the inverter based on the detection voltage and the target value. 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.

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.

A semiconductor device has a transparent dielectric substrate such as a sapphire substrate. To enable fabrication equipment to detect the presence of the substrate optically, the back surface of the substrate is coated with a triple-layer light-reflecting film, preferably a film in which a silicon oxide or silicon nitride layer is sandwiched between polycrystalline silicon layers. This structure provides high reflectance with a combined film thickness of less than half a micrometer.

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 (sintered body) is formed to obtain the bonding member according to the present invention. In the bonding member, a chromia layer including Cr2O3, a first layer including elements of Mn, Co, Fe, Cr, and O, and a second layer including elements of Mn, Co, Fe, and O are provided in this order from the side close to the interconnector at the bonding portion between the bonding agent and the interconnector. The bonding member has sufficiently great bonding strength between the interconnector and the bonding agent.

This invention enables setting of a diagnosis algorithm of a safety device to be easily carried out. A slice I/O unit stores a plurality of diagnosis algorithms each corresponding to a different safety device in an ASIC, and stores specifying information for specifying a diagnosis algorithm to use of the plurality of diagnosis algorithms in a register of the ASIC. The slice I/O unit performs diagnosis of a connected safety device using the diagnosis algorithm specified by the specifying information stored in the register of the plurality of diagnosis algorithms. The diagnosis algorithm to use can be selected by selecting a number, and the like, which is preferable as a setting process at a setting tool device can be facilitated and a human error does not occur.
