The purpose of the present invention is to improve the water absorption of a water-absorbent resin without sacrificing the productivity, production cost, safety, and so on. Provided is a sustainable and renewable water-absorbent resin with excellent whiteness, which is suitable for mass consumption as disposal diapers or the like, and which can dispense with excessive purification of raw material acrylic acid. Also provided is a process for the production of a water-absorbent resin, which comprises: a step of preparing acrylic monomers; a step of polymerizing the monomers; and a step of drying the obtained aqueous gel, wherein the monomers at the time of polymerization contain at least 400 ppm of propionic acid.

A booster circuit generates a boosted output by boosting a low voltage output supplied as a target to be boosted and feeds back a part of the boosted output, an output by the booster circuit itself, to the booster circuit as operation energy. An auxiliary booster circuit outputs start-up energy generated based on a low voltage output to the booster circuit as start-up energy that is necessary for starting up the booster circuit.
