Abstract: Provided is a system for providing mineral-containing drinking water that makes it possible to easily obtain mineral-containing drinking water at home. According to the present invention, a system for providing mineral-containing drinking water comprises: a first container that contains a pressurized gas and a 1-10 mL single-use quantity of a concentrated mineral liquid composition that is to be used at a dilution rate of 100-1000 times; and a second container that holds 1-3 L of water. The first container can be attached as a lid part of the second container. When the first container has been attached as a lid part of the second container, the concentrated mineral liquid composition in the first container can be sprayed into the second container.

Abstract: A power supply control apparatus for an electric vehicle includes a main circuit including a smoothing capacitor connecting a power supply to an electric load driven by the power supply to smooth a fluctuation in an input voltage to the electric load, a main contactor interposed between the power supply of the main circuit and the electric load, and a precharge circuit connected in parallel with the main contactor and including a precharge contactor and a resistance element. When a timeout occurs before precharging by the precharge circuit is completed, the power supply control apparatus permits a retry of the precharging if the precharging is retried without any disadvantage.
