摘要:
A processing state management apparatus to be connected to a distribution server that carries out a transaction to register or delete content to be distributed, includes a transmitter which transmits a request requesting the distribution server to carry out the transaction, and a state updater which, after the processing state management apparatus has requested the distribution server to carry out the transaction, holds state information indicative of the state of the transaction in the distribution server as representing processing in progress until the processing state management apparatus receives a notification of completion of the transaction from the distribution server.
摘要:
A processing state management apparatus holds state information indicating the state of transaction processing in a distribution server as in progress after the processing state management apparatus connected to the distribution server requests the transaction processing to the distribution server which executes the transaction processing to register or delete contents to be distributed until the processing state management apparatus receives the notification of completion of the transaction processing from the distribution server.

A body of a hydrogen generator includes a reformer configured to generate a reformed gas mainly containing hydrogen, a material passage configured to supply a reforming material, which is a material for a reforming reaction, to the reformer, a shifter configured to convert CO contained in a reformed gas obtained from the reformer into CO2, a reformed gas passage configured to supply the reformed gas obtained from the reformer to the shifter, and a passage for the shifted gas obtained from the shifter. The shifted gas passage and the material passage are adjacent to each other with a shared horizontal wall interposed therebetween, and thereby, heat from the shifted gas and radiant heat from the downstream end face of the shifter are transferred to the reforming material that travels in the material passage.

It is not possible to store heat of a domestic hot water supply level at a high density. If thermal storage temperature is T, variation in enthalpy in a chemical reaction is ΔH, variation in entropy is ΔS, and variation in free energy is ΔG, a thermal storage material satisfying a relationship of TΔS≧ΔG is used under a condition of ΔH>0 so as to promote a reaction for putting the thermal storage material in a thermal storage reaction portion in an energy storing state by having supplemental energy added by an electrode portion when putting the thermal storage material in the energy storing state by decomposing or separating it.

A video signal recording and playback apparatus includes: a unit for checking at least one external video device connected to a main unit via a predetermined interface to determine a video device which is recording, the main unit having a control section for transmitting and receiving video signals to/from at least one video device and controlling the device; a unit for checking at least one video device connected via the predetermined interface to determine a video device capable of performing playback while recording; a unit for determining a video device, which is recording and is capable of performing playback while recording, at least one video device as a control target connected via the predetermined interface and determining playback with respect to the control target device in recording; and a unit for allowing the control target device in recording to perform the determined playback when an operation section is operated.
摘要:
The fuel cell humidifying system is to prevent freezing and clogging of a water permeable type humidifier by providing a gas passage switching device for changing the gas flow paths communicating with the humidifier. To direct the flow of dry air exiting from the supercharger to the exhaust passage in the humidifier, the gas passage switching device includes a first three-way valve, a second three-way valve, a flow adjusting valve and a sweep piping. In this system, water vapor in the humidifier which causes freezing can be swept off by flowing dry air through the exhaust gas passage in the humidifier, and therefore, clogging caused by ice particles which plug up the pores of the hollow thread membrane in the humidifier can be prevented.
