摘要:
A gas sensor (100) includes an oxygen pump cell (135) and an oxygen-concentration detection cell (150) laminated together with a spacer (145) interposed therebetween. The spacer (145) has a gas detection chamber (145c) which faces electrodes (137, 152) of the cells (135, 150). The oxygen-concentration detection cell (150) produces an output voltage corresponding to the concentration of oxygen in the gas detection chamber (145c). The oxygen pump cell (135) pumps oxygen into and out of the measurement chamber (145c) such that the output voltage of the oxygen-concentration detection cell (150) becomes equal to a predetermined target voltage. A leakage portion mainly formed of zirconia is disposed between which electrically connects the oxygen-concentration detection cell (150) and the oxygen pump cell (135).

摘要:
An electronic component cooling unit includes a housing having a flow path in an interior of the cooling unit. The flow path circulates a cooling medium. Two surfaces, that is, a top surface and a bottom surface, are located at the housing. Electronic components are mounted to the housing, and side surfaces are located at the housing and surround the top surface and the bottom surface. Multiple opening portions are located at the side surfaces and communicate with the flow path. A closing member closes the opening portion or each opening portion other than the opening portions that corresponds to a supply opening and a discharge opening for the cooling medium.

A wastewater treatment apparatus (10) that treats the wastewater containing persistent substances, according to the present invention, includes a wastewater treatment bath (12) for treating a wastewater (11), an oxidizing reagent adding unit (14) for adding an oxidizing reagent (13) in the wastewater treatment bath (12), and an alkaline reagent adding unit (16) for adding an alkaline reagent (15) in the wastewater treatment bath (12). By making the wastewater in the wastewater treatment bath (12) in the alkaline condition, it is possible to completely decompose the persistent substances in the wastewater by the oxidation treatment using an oxidizing reagent.
摘要:
There is provided a refrigeration apparatus in which a refrigerant accumulating in non-operating outdoor units is supplied to an outdoor unit being operated in which a shortage of refrigerant occurs without starting the compressors of the non-operating outdoor units. In the control method for the refrigeration apparatus in which to refrigerant piping 10 installed between the indoor side and the outdoor side, a plurality of outdoor units 30A, 30B each including a compressor 31, a directional control valve 34, an outdoor heat exchanger 35, an outdoor expansion valve 36, and an accumulator 37 are connected in parallel on the outdoor side, and each of the outdoor units is provided with a hot gas bypass circuit 38 that includes a solenoid valve 38a and an expansion mechanism 38b arranged in series, and is connected between high-pressure side piping 33a on the discharge side of the compressor and low-pressure side piping 33b on the accumulator side, if a shortage of refrigerant occurs when air cooling operation is performed in a state in which only the outdoor unit 30A is operated and other outdoor units 30B are not operated, the solenoid valves 38a of the non-operating outdoor units 30B are opened so that the refrigerant accumulating in the non-operating outdoor units 30B is supplied to the outdoor unit 30A via the hot gas bypass circuit 38 and the low-pressure piping 33b.
摘要:
The present invention is to allow prompt and reliable synchronization of belonging information management table even in environments where there is a possibility of receiving update notification information from a plurality of wireless base stations, without needing unnecessarily large traffic for synchronization of belonging information management table. Wireless base station stores belonging information management table, to which belonging information of a terminal belonging to the base station is associated with, to new/old judgment information for judgment of new/old of update. Belonging information update unit performs update of belonging information including the new/old judgment information thereof. Further, upon receiving update notification information from other wireless base station, the belonging information update unit updates the belonging information management table based on the update notification information. The update notification information includes at least updated portion in the belonging information and new/old judgment information.

摘要:
A wireless communication system allocates resource information used in performing wireless communication to wireless base stations in order not to generate interference between access-side wireless interfaces and backbone-side wireless interfaces. Each of the wireless base stations includes an access-side wireless interface for covering wireless terminal devices and a backbone-side wireless interface for connecting the wireless base stations with each other. The wireless base station allocates resource information that is common to the wireless base stations to the backbone-side wireless interface that performs the wireless communication between the wireless base stations, and allocates resource information that does not generate interference with the backbone-side wireless interface to the access-side wireless interface.
