Abstract: A control apparatus controls an electric power supply apparatus configured to supply electric power to a working machine. The electric power supply apparatus is provided with a fuel cell. The control apparatus is provided with a restriction request acquisition unit configured to acquire a restriction request for requesting restriction of the supply of the electric power via a communication network, and a restriction unit configured to restrict the supply of the electric power in a case where the restriction request acquisition unit acquires the restriction request. The control apparatus may be provided with an end detection unit configured to detect end of use of the working machine. The restriction unit may decide to start the restriction in a case where, after the restriction request acquisition unit acquires the restriction request, the end detection unit detects the end of the use of the working machine.

Abstract: Provided is a compound represented by formula (I): or an N-oxide compound thereof, wherein the variable groups are as defined in the specification. Also provided is an arthropod pest control agent containing a compound represented by formula (I) and an inert carrier. The compound represented by formula (I) and arthropod pest control agent exhibit an excellent controlling effect against arthropod pests.

Abstract: A vehicle impact attenuator that can be installed at low cost in a narrow installation space, immediately stop a colliding vehicle, and effectively mitigate the impact on the vehicle. The vehicle impact attenuator includes a shock absorber that deforms upon a collision by a vehicle to reduce the impact on the vehicle. A support is provided for the shock absorber and a holding portion holds the support (20A) in a vertical position in an installation area. The support has cuts made in it that upon application of a load equal to or exceeding a set value, fracture and function as a release mechanism to thereby release the support from being held in a vertical position in the installation area. The support is deformable by a load less than the set value.

Abstract: Disclosed is a vibration test method for evaluating the vibration resistance of a specimen, comprising a test specification setting step (S10) of determining reference vibration conditions for the specimen based on transport conditions during actual transportation; a reference value attainment step (S20) of calculating an amplitude level and a reference accumulated fatigue value of the specimen under the reference vibration conditions; a test condition determination step (S30) of determining test vibration conditions and a test time based on an allowable amplification factor of the amplitude level and a desired vibration time, so that an accumulated fatigue value which is calculated from the vibration detection value of the specimen satisfies the reference accumulated fatigue value; and a vibration-imparting step (S40) of vibrating the specimen based on the test vibration conditions and the test time.

Abstract: A vehicle impact attenuator that can be installed at low cost in a narrow installation space, immediately stop a colliding vehicle, and effectively mitigate the impact on the vehicle; the vehicle impact attenuator comprising: a shock absorber (10A) that deforms upon a collision by a vehicle to reduce the impact on the vehicle; a support (20A) for the shock absorber (10A); and a holding portion (30A) that holds the support (20A) in a vertical position in the installation area; the support (20A) having cuts (31A) that, upon application of a load equal to or exceeding a set value, fracture and function as a release portion to thereby release the support from being held in a vertical position in the installation area; and the support (20A) being plastically deformable by a load less than the set value.
