Abstract: A battery pack includes a plurality of batteries, thermally conductive members which are in contact with the plurality of batteries, and a case which houses the plurality of batteries and the thermally conductive members. The case includes holding parts each of which is not in contact with an end surface of the thermally conductive member, regulates displacement of two surfaces of the thermally conductive member in a direction vertical to each of the two surfaces which are connected with the end surface and positioned on sides opposite to each other, is in contact with at least one of the two surfaces, and thereby holds an end part of the thermally conductive member.

Abstract: A partial structure of a battery pack includes: a battery group which is formed by stacking a plurality of layers, each of the layers being formed by arranging cylindrical batteries in parallel in a plane, the cylindrical batteries belonging to adjacent layers being arranged by shifting alignment pitches by a half pitch from each other between the adjacent layers; heat transfer plates, wherein each of the heat transfer plates is in contact with side surfaces of the cylindrical batteries arranged on both surfaces of each of the heat transfer plates, is formed by a heat transfer corrugated plate member, and extends through a gap between the cylindrical batteries along an alignment direction of the cylindrical batteries in the layers in the plane intersecting center axis lines of the cylindrical batteries, a first intersection direction intersecting the alignment direction or a second intersection direction intersecting the alignment direction and the first intersection direction; and a radiator which is arrange

Abstract: A combustion apparatus includes a combustion part, a blower fan, an ignition device, and a control part. The control part selectively performs continuous combustion in which the combustion part is operated to burn continuously and intermittent combustion in which a combustion period and a non-combustion period of the combustion part are repeatedly provided. When the continuous combustion is stopped, the control part extinguishes the combustion part and operates the blower fan to perform a scavenging operation. When the combustion period in the intermittent combustion is ended, the control part extinguishes the combustion part and operates the blower fan to perform a scavenging operation in the non-combustion period. A total air blowing amount of the blower fan in the scavenging operation during the non-combustion period is set to be less than a total air blowing amount of the blower fan in the scavenging operation when the continuous combustion is stopped.

Abstract: A vehicle driving apparatus includes a first motor, a second motor, and a planetary mechanism, and obtains a driving force by combining motive forces obtained from the first motor and the second motor by a planetary gear of the planetary mechanism. The vehicle driving apparatus includes at least one of a design value and a control quantity in which a frequency ratio between a sound generated by a rotation of the first motor and a sound generated by a rotation of the second motor satisfies a reduction condition of dissonance.

Abstract: A storage battery module rental system includes a storage battery module prepared in each providing point that is dispersedly distributed and that can be rented to a user, an acquisition unit configured to acquire individual information of a plurality of the users and module information from the storage battery module, the user being a rentee candidate of the storage battery module, a determining unit configured to determine an incentive given for renting the storage battery module based on the individual information and the module information in such a way that the incentive could differ for each user; and a notifying unit configured to notify the user of the incentive determined by the determining unit for each of the users.

Abstract: The combustion device includes: a burner; an igniter; a fuel supply unit that supplies fuel to the burner; a blower fan that supplies air for combustion; an exhaust port that discharges combustion exhaust; a device control unit that, before ignition of fuel supplied to the burner by operation of the igniter, performs air purge of the burner at a predetermined air blowing amount by driving the blower fan; and a setting means that is set when a check valve for preventing back flow of exhaust is connected to the exhaust port. When the setting means is set to indicate that the check valve is connected, the device control unit controls the operation of the blower fan so that slow-start air purge is performed in which the time interval from the start of air purge until the predetermined air blowing amount is reached becomes longer, than in the case in which no such check valve is connected.

Abstract: An exhaust portion is connected to a lower peripheral edge of a secondary heat exchanger case, has an exhaust vent configured to exhaust combustion gas which has passed through the secondary heat exchanger case, and has a bottom surface including a first face parallel to the lower peripheral edge. A drainage water discharge port is configured to discharge drainage water from the first face of the bottom surface. The drainage water discharge port is provided, to avoid a region overlapping with the secondary heat exchanger case from a point of view as seen in an up-down direction, in an exhaust path from the secondary heat exchanger case toward the exhaust vent.
