Abstract: A management apparatus includes: an extractor that extracts, on the basis of a predetermined condition, one or more utterance histories from a plurality of utterance histories each indicating the content of a voice caused to be output by a first device (e.g., utterance device); and a display controller that causes a second device (e.g., display device) to display information indicating the one or more utterance histories.

Abstract: A voice speech device includes: a display; a selector that causes the display to display one or more candidates for a name to be provided to a target appliance (appliance), and accepts selection of one name among the one or more candidates; a receiver for receiving first state information that is sent from the target appliance and indicates a state of the target appliance; a speech sentence creator that creates a speech sentence for notifying the state of the target appliance, based on the first state information received by the receiver, the speech sentence containing the one name accepted by the selector; and a voice outputter that outputs the speech sentence by voice.

Abstract: A voice control method according to the present disclosure includes: judging, for each of a plurality of utterance objects capable of outputting voice, whether the utterance object is outputting voice; and based on a result of the judging, causing one or more of the plurality of utterance objects to output voice at one of a timing of immediately outputting voice and a timing of outputting voice after an end of outputting voice by an utterance object which is outputting voice among the plurality of utterance objects.

Abstract: An insulation box unit and a refrigerator of the present invention employs i) rigid urethane foam with a 8.0 MPa-or-greater bending modulus, and a 60 kg/m3-or-lower density, and ii) a vacuum insulation material. The proper bending modulus provides the insulation box unit with a substantial strength, even in the case that the coverage of the vacuum insulation material with respect to the surface of the outer box exceeds 40%. The proper density prevents the insulation box unit from poor insulation efficiency due to undesired solid thermal conductivity. Despite of an extended use of the vacuum insulation material, the insulation box unit offers an excellent insulation efficiency and therefore accelerates energy saving. According to the recycling method of the present invention, rigid urethane foam formed of tolylene di-isocyanate composition, which was separated from refrigerator wastes, is recycled as a material of rigid urethane foam.

Abstract: A refrigerator is improved in storage environment by suppressing drying and oxidation and enhanced in volume efficiency and cooling efficiency. The refrigerator includes a refrigerating chamber, a vegetable chamber, and a freezing chamber in order from its top to its bottom. Cool air is introduced into the freezing chamber by a first cooler and a first fan, and is introduced into the refrigerating chamber by a second cooler and a second fan. These chambers function as a direct cooling chamber. The vegetable chamber functions as an indirect cooling chamber cooled by a cooling plate which is disposed at the top of the chamber and has a large thermal conductivity, which is cooled by forced convection by the second cooler and the second fan, producing the effects of low temperature radiation and natural convection in the chamber.
