Abstract: An electric power generation control system for a vehicle, which enables generation of electric power by a generator as much as possible while preventing an electrical component from being overheated by power generation by the generator. The electric power generation control system selectively switches a mode of the generator between first and second modes in which an instruction voltage is higher and not higher than an allowable voltage of a wire harness, respectively. A counter value is counted up in the first mode and down in the second mode. When the counter value has reached a higher limit value, the first mode is inhibited and the power generation mode is set to the second mode. This increase the proportion of an execution time period of the first, and accordingly, when a possibility of overheating the wire harness becomes high, the instruction voltage is lowered.

Abstract: Non-destructive testing system performs accurate testing as to whether lamination joining portion of different metal materials is in strong joining state by secure metal joining. The system sets a lamination joining portion of different metal materials of a work to a certain position and angle. Laser light in certain waveform is applied to lamination joining portion surface to capture images by infrared camera, and data processing device obtains infrared images. Based on infrared images, Fourier transform is performed on each pixel of infrared images, and phase image is created by console device. Based on created phase image, effectiveness/defectiveness of joining is determined. In this non-destructive testing, whether reflection by vertical wall in vicinity is significant is determined, based on intensity of infrared images obtained immediately after irradiation with laser and angle between laser light optical axis and testing part surface is finely adjusted to obtain infrared images with less noise.

Abstract: In a balancer device (10) including a pair of balancer shafts (11, 21), the radial bearings (41-44) for the balancer shafts are formed solely in the balancer housing (30) and/or an integral extension (52) thereof.
