Abstract: A storage battery control method used by a control device controlling a storage battery prepared for a plurality of consumers, and involves detecting an amount of power used by each of the consumers per unit time, making a judgement regarding whether or not the amount of power used by one or more of the consumers exceeds a threshold determined in advance, and when the judgement finds that the amount of power used by the consumers exceeds the threshold, supplying electric power from the storage battery to a distribution system to which the one or more consumers belong.

Abstract: Frozen products requiring cold insulation are housed inside of the cold-insulating container structured of a vacuum heat-insulating material, and the cold-insulating containers are loaded in a refrigerator vehicle, cold-insulating vehicle, or room-temperature vehicle other than a freezer vehicle for delivery. Each of the peripheral walls, lids, and bottom faces of this container is made of a sheet material enveloping the vacuum heat-insulating material therein. In each of the peripheral walls adjacent to the peripheral walls connected to the lids, the vacuum heat-insulating material is divided along folding line so as to be foldable.

Abstract: To provide a self-diagnosing apparatus for a refrigerator which self-diagnoses an operation condition and advises a user of an appropriate improvement action if there is an abnormal. First, a detector such as an internal temperature sensor detects a plurality of condition-indicative quantities with respect to the refrigerator, and the condition-indicative quantities are stored in a memory part for a predetermined period. A diagnostic device such as a diagnosis calculation value judging part compares the condition-indicative quantities or a diagnosis calculation value which is calculated based on the condition-indicative quantities with a predetermined threshold value, and judges whether the operation condition of the refrigerator is normal or abnormal based on a result of the comparison.
