    摘要： The invention relates to a method for decomposing bromate ions contained in a liquid. The method includes the sequential steps of bringing the liquid into contact with a photocatalyst; and irradiating the photocatalyst with a light ray having an energy that is not lower than that of a band gap of the photocatalyst, thereby generating a photocatalytic reaction to decompose the bromate ions. The invention further relates an apparatus for decomposing bromate ions contained in a liquid. The apparatus includes a first section for generating therein a photocatalytic reaction to decompose the bromate ions; a photocatalyst adapted to be brought into contact with the liquid in the first section; and a light source for irradiating the photocatalyst with the light ray such that the photocatalytic reaction is generated in the first section when the photocatalyst is in contact with the liquid. Thus, it is possible to efficiently and stably decompose the bromate ions. The photocatalyst may be at least one metal oxide including titanium and a metal having an electronegativity lower than that of titanium. In this case, it is possible to omit pH adjustments of the liquid before and after the photocatalytic reaction.

    摘要： In method and apparatus for protecting a plurality of same semiconductor switching elements used in a PWM inverter from being overheated, a junction temperature rise T n of one of the switching elements is derived on the basis of an output frequency of the inverter (ωc), an output current (I) of the inverter, and a control factor (a) and when T n > T nref , the overheat in the corresponding switching element occurs so that a gate signal for each switching element is not inputted or an PWM off duty ratio on a pulse duty ratio of the gate signal is increased to limit the output current of the inverter.
