A relay device includes a communication signal relay unit for relaying a communication signal and a wake-up signal relay unit for relaying, by bypassing the communication signal relay unit, a wake-up signal that is transmitted using a frequency band which is lower than a communication frequency band used in transmitting the communication signal. The communication signal relay unit includes a low frequency wave attenuation unit for attenuating a signal with a frequency band lower than the communication frequency band. The wake-up signal relay unit includes a wake-up signal filter unit for passing through a signal with a frequency band lower than the communication frequency band.

An AC component I addition unit of a diagnostic device superimposes an alternating current on an output current of a fuel cell. A Zn calculation unit calculates a cell impedance with respect to the alternating current with regard to any of a plurality of cells. A diagnosis unit diagnoses that any cell is subjected to hydrogen deficiency when an absolute value of the cell impedance exceeds (absolute value of a reference impedance+a predetermined value ). It is diagnosed that any cell is subjected to oxygen deficiency when the absolute value of the cell impedance is smaller than (absolute value of the reference impedancea predetermined value ).

A control device has two modes as control modes of an electric power supply to an electromagnetic solenoid, which are used when a first determining unit determines that a difference between a sensed value of a phase and a target value of the phase exceeds a permissible range. One of the modes is a special mode that is used when a second determining unit determines that the sensed value of the phase reaches a threshold value. Another one of the modes is a normal mode that is used when the second determining unit determines that the sensed value of the phase does not reach the threshold value. In the special mode, the control device controls supply of the electric power to the electromagnetic solenoid in such a manner that an opening degree of an advancing port is larger than the opening degree of the advancing port in the normal mode.

An advance indication part performs an advance indication of operation of a robot by using a movable part in correspondence to an operation program or a command supplied to the robot. When the advance indication part performs the advance indication, a user detection part detects a user in a predetermined area of movement of the movable part based on a picture image taken by a camera. When the user detection part detects the user, a recognition check part checks whether the detected user has recognized the advance indication of the advance indication part. When the recognition check part determines that the detected user has not recognized the advance indication yet, a recognition promotion part promotes the detected user to recognize the advance indication or an operation of the robot.

A solenoid device includes two electromagnetic coils, two stationary cores, two plungers and a yoke that surrounds the two electromagnetic coils. When a first electromagnetic coil is energized, magnetic flux flows through a first magnetic circuit that includes the first stationary core. When the two electromagnetic coils are energized, magnetic flux of the first electromagnetic coil flows through the first magnetic circuit, and magnetic flux of the second electromagnetic coil flows through a second magnetic circuit that includes a second stationary core. When energization of the first electromagnetic coil is stopped while maintaining energization of the second electromagnetic coil, the magnetic flux of the second electromagnetic coil continues to flow through the second magnetic circuit and a third magnetic circuit that includes the two stationary cores. A magnetism limiting portion is disposed in a portion of the second magnetic circuit that does not overlap the third magnetic circuit.

In an aerial vehicle, a malfunction determiner determines whether there is a malfunction in one of thrusters of the aerial vehicle. A flight controller activates the thrusters, and controls the output of each of the thrusters. The flight controller deactivates, when it is determined that there is a malfunction in one of the thrusters as a malfunctioned thruster, the malfunctioned thruster. The flight controller deactivates a selected thruster in the thrusters; the selected thruster being paired to the malfunctioned thruster, and controls the active thrusters except for the deactivated thrusters in all the thrusters to make the flight attitude of the aerial vehicle stable. The flight controller controls the active thrusters to cause the aerial vehicle to land while maintaining the flight attitude of the aerial vehicle being stable.

An aerial vehicle is provided which includes first thrusters with first propellers and second thrusters with second propellers. Each of the first propellers has a first rotating region in which blades thereof rotate. Similarly, each of the second propellers has a second rotating region in which blades thereof rotate. Each of the first rotating regions is located to overlap one of the second rotating regions, as viewed in a direction of a yaw axis of the aerial vehicle. The first rotating regions are located away from the second rotating regions in the direction of the yaw axis. Such layout of the first and second propellers eliminates physical interference therebetween. The overlap between the first and second propellers results in a decreased cross-sectional area of projection of the aerial vehicle from the front view in a flight direction thereof.

A semiconductor device includes a semiconductor module. The semiconductor module includes a package made of resin. The package contains a semiconductor element and a heat sink. The heat sink has a thermal conductive surface exposed on a part of one surface of the package. The semiconductor device includes an insulating plate, which is a part of a cooler, facing the thermal conductive surface of the heat sink and a resin surface around the thermal conductive surface, and pressed against the semiconductor module. At least a part of the thermal conductive surface comprises a recessed region recessed with respect to the resin surface. A solid heat transfer layer is interposed between the recessed region of the thermal conductive surface and the insulating plate, and is not interposed between the resin surface and the insulating plate.

A flight guidance system is provided which includes an aerial vehicle unit and a navigation display unit. In use, the navigation display unit is placed on the ground, a wall, a ceiling, or a floor of a structural object and indicates navigation information for the aerial vehicle unit. The aerial vehicle unit optically reads the navigation information out of the navigation display unit to determine an installation position where the navigation display unit is disposed and also determine a flight position thereof based on the installation position. This enables the aerial vehicle unit to continue to fly along a given flight route without need for complicating the structure and operation thereof in an area where it is difficult for the aerial vehicle unit to receive navigation signals such as GPS signals.

A parallel running vehicle detecting apparatus is provided, which includes a first distance sensor for detecting distance of an object in a first detection area on a rear lateral side of a vehicle, a second distance sensor for detecting distance of an object in a second detection area, a parallel running vehicle detector for detecting a parallel running vehicle based on detections of the first and second distance sensors, and a storage for storing a detection distance history of the second distance sensor. The parallel running vehicle detector is provided with multiple determination conditions for determining whether the object detected by the first distance sensor is the parallel running vehicle, and changes the parallel running vehicle determination condition based on the detection distance history stored in the storage.
