    • A method of and an apparatus for determining the individual existence of first and second groups of particles contained in a fluid and differing in characteristics from each other that are capable of, e.g., during an automatized ion exchange operation, individually distinguishing anionic and cationic ion-exchange resin particles and capable of easily monitoring their regeneration state. A plurality of beams comprising different wavelength bands are emitted from light-emitting elements, projected onto a subject of measurement containing first and second particles, and received by light-receiving elements, and the reflectivities of the beams are measured. When the ratio of the reflectivity of a first of the beams to that of a second of the beams is above a predetermined value, the subject of measurement is determined to contain particles of the first kind, whereas when that ratio in reflectivity is below the predetermined value, the subject of measurement is determined to contain particles of the second kind.

    • A portable travel electric steam iron which also functions as a steamer has an aperture provided in a rear portion of the bottom of a water tank which supplies water into steam generating chambers from the water tank. Water dripping through the aperture is received by a water receiving surface provided on the center or on the front side of the center of a base. A handle which includes two straight positions separated by a bend is securable to an iron main body both in the operative position and storage position. An actuator for opening and closing an aperture is disposed in a space above the water tank, in the vicinity of a fixing portion at which the handle is fixed to the iron main body, thus providing a compact construction which is easy to handle.
