Abstract: A smoothing capacitor is forcibly discharged, in a state where a battery is disconnected from a high-voltage circuit, first discharge control is initiated to consume electric charges of the smoothing capacitor by an in-vehicle component via a DC/DC converter. Thereafter, when a voltage of the smoothing capacitor is reduced and reaches a specified threshold, second discharge control is executed to forcibly discharge the electric charges in an active discharge circuit. In the case where continuous forced discharge occurs, delay control to delay execution timing of the second discharge control is further executed.

Abstract: To provide a contactor failure determination apparatus capable of appropriately determining failure of a contactor provided in a vehicle, a voltage sensor capable of detecting rising or dropping of a voltage of a second circuit including an external charger is provided. When an external charging request is made, a first control for closing each external charging contactor is executed, a second control for closing a pre-charge contactor is executed after execution of the first control, a third control for closing a second main contactor is executed after execution of the second control, and response to the voltage sensor detecting that the voltage of the second circuit has not risen after execution of the third control, it is determined that at least one of the external charging contactors has failed in an open state.

Abstract: To provide a contactor failure determination apparatus capable of appropriately determining failure of a contactor provided in a vehicle, a voltage sensor capable of detecting rising or dropping of a voltage of a second circuit including an external charger is provided. When a vehicle start request is made, a first control for closing one external charging contactor is executed, a second control for closing a pre-charge contactor is executed after execution of the first control, a third control for closing a main contactor, which is not parallel with the pre-charge contactor, is executed after execution of the second control, and in response to the voltage sensor detecting that the voltage of the second circuit has risen after execution of the third control, it is determined that the other external charging contactor has failed in a closed state.

Abstract: A vehicle collision avoidance assist apparatus keeps stopping a collision avoidance control to avoid a collision of an own vehicle with an object ahead of the own vehicle when the own vehicle turns, a predetermined condition is satisfied, and a collision condition is satisfied. While the own vehicle turns, the apparatus acquires an own vehicle turning angle which is an angle which the own vehicle has turned about a turning center from when the own vehicle starts turning and change the predetermined condition, depending on the own vehicle turning angle.

Abstract: A power control device for a power supply mounted on a vehicle is provided, which includes a generator mounted on the vehicle and configured to regenerate power from kinetic energy of the vehicle, a high-voltage battery configured to accumulate the power regenerated by the generator, a low-voltage battery of which a nominal voltage is lower than the high-voltage battery, a voltage converter configured to lower an output voltage from the high-voltage battery and charge the low-voltage battery at the lower voltage, and a controller configured to control the voltage converter. The controller operates the voltage converter to start the charging of the low-voltage battery after the vehicle is powered ON and before an engine mounted on the vehicle is started.

The present invention provides a composition for inhibiting myofibrosis containing quercetin or a glycoside thereof as an active ingredient.

Abstract: The object of the invention is to provide a new composition for suppressing fatty degeneration of a muscle, the composition including a component that is safe and suitable for a long term intake. It was found that quercetin or a glycoside thereof suppresses a differentiation process from myosatellite cells into adipocyte-like cells. In the present invention, quercetin or a glycoside thereof is used in a composition for suppressing fatty degeneration of a muscle.

Abstract: An object of the present invention is to provide a new muscle atrophy inhibitor comprising a component that is safely ingestible for a long time. It was found that glycosides of quercetin, a polyphenol present in plants, etc., have inhibitory activity on the expression of myostatin involved in muscle atrophy. This invention provides a new muscle atrophy inhibitor comprising a quercetin glycoside which is excellent in absorbability into the body and high in safety.
