Abstract: A health status management system includes circuitry to measure a pulse wave of a user to obtain objective evaluation data for objective evaluation in relation to a mental health status, obtain one or more answers of the user to one or more questions related to the mental health status as subjective evaluation data for subjective evaluation in relation to the mental health status, control a period of measuring the pulse wave and a period of performing the subjective evaluation to overlap with each other, control a start time of the period of measuring the pulse wave to be earlier than a start time of the period of performing the subjective evaluation, transmit, to additional circuitry, the objective evaluation data and the subjective evaluation data, and display, on a screen, information on the objective evaluation and information on the subjective evaluation.

Abstract: A digital camera with a printer includes an imaging unit, a print unit that prints an image on a medium and discharges the printed medium, a display unit, a first operation member that is rotated from a first position in a first direction around a rotation axis against biasing force, and is rotated in a second direction opposite to the first direction by the biasing force to be returned to the first position in a case in which the first operation member is released, and a processor. The processor performs specific control in accordance with operation of the first operation member.

Abstract: A ZnO--Pd composite catalyst wherein Pd is dispersed and fixed on the surface of ZnO is produced by ion adsorption process having the steps of soaking ZnO in an acid solution of Pd to adsorb Pd ions (Pd.sup.2+) onto the surface of ZnO; and reducing the adsorbed Pd ions to metallic Pd particles so that the metallic Pd particles are substantially evenly deposited on the surface of ZnO. The ZnO--Pd composite catalyst provides a stable and continuing CO oxidizing capability, without light irradiation, even when the air to be treated contains sulfur compounds such as H.sub.2 S and SOx.

Abstract: An air-purifying filter includes a carrier base and a TiO.sub.2 -Pd composite catalyst supported on the carrier base. CO in air treated by the filter is adsorbed onto the Pd surface and thus decomposed by oxidization to CO.sub.2, whereas sulfur compounds in the air are adsorbed onto the Pd surface and then transferred to the TiO.sub.2 surface where they are decomposed by oxidization to SO.sub.4.sup.-2 when the TiO.sub.2 is subjected to irradiation. Preferably, Pd exists in a relatively small quantity at a first side of the carrier base in the vicinity of a light source and in a greater quantity at a second side opposite the first side. The first side is preferably located upstream relative to flow of air treated by the filter. An air-purifier utilizing this filter is mounted in an automobile, preferably on a rear shelf or in a trunk compartment.
