The power conversion device converts the received DC power into AC power and transmits it to a power system. A plurality of air lead-in tubes are laid in parallel. Each of the air lead-in tubes includes a heat exchange part, an opening part, and a lead-in part. The heat exchange part is buried in a ground at a ground surface on a back surface of a solar cell panel. The opening part is exposed to the ground surface. The lead-in part is an opening that communicates with an interior of a building in which the power conversion device is installed. The air lead-in tubes are constructed to draw air in the heat exchange part from the lead-in part by using a sucking mechanism.

The cooling fan control circuit is configured to, if the temperature sensed by the temperature sensor is higher than a predetermined temperature, turn on the cooling fan, and if the sensed temperature is equal to or below the predetermined temperature, control the cooling fan to turn off the cooling fan or make a speed of the flowing air lower than a speed when the cooling fan is in the on state.

Power conversion device

A power conversion device capable of suppressing air from flowing back into a housing is provided. The power conversion device includes a power conversion unit configured to perform power conversion, a housing for accommodating the power conversion and having an air inlet and an air outlet, a fan provided inside the housing and generating airflow in such a manner that air flows to the outside of the housing via the air outlet after flowing into the housing via the air inlet, and a cover provided at the air outlet, the cover being configured to be brought into an opened state with respect to the air outlet if the airflow generated by the fan is stronger than airflow moving from the outside of the housing toward the air outlet, and to be brought into a closed state with respect to the air outlet if the airflow generated by the fan is weaker than the airflow moving from the outside of the housing toward the exhaust of the housing.

According to one embodiment, an electrical equipment housing includes a first storage room, an air conditioner, a second storage room, a temperature sensor, and a heater. The first storage room contains a power converter converting electrical power. The air conditioner adjusts a temperature inside the first storage room. The air conditioner includes an indoor unit and an outdoor unit. The indoor unit is provided inside the first storage room. The outdoor unit is provided outside the first storage room. The second storage room contains the outdoor unit. The temperature sensor senses a temperature inside the second storage room. The heater heats inside the second storage room when the temperature sensed by the temperature sensor is a lower limit or less.

One object is to allow communication by sound/voice other than user speeches in voice chatting. A system according to an embodiment includes a plurality of terminal devices and a server communicatively connected to the terminal devices; and the system allows voice chat between users of the terminal devices. In the system, the terminal devices of the users who are members of a chat unit and participating in the chat unit perform the voice chat communication for implementing the voice chat in the chat unit. The terminal device of one user who is a member of the chat unit makes a play request for an audio file selected by the one user to the terminal device of another user who is a member of the chat unit based on an instruction from the one user, and the terminal device of the other user plays the audio file.

Disclosed are an apparatus for the identification of a ribonucleic acid, whereby not only the molecular weights of digestion products, from which nothing but the nucleic acid residue composition can be understood, but also nucleic acid residue sequence data is obtained from a product ion mass set and thus the identification reliability for the individual digestion products can be remarkably improved; a method for the identification of a ribonucleic acid; and a program and system for the identification of a ribonucleic acid. The method as described above comprises: searching for nucleic acid sequence database by using a fragment mass set indicating the molecular weights and inner structural data of individual oligonucleotides that are obtained by tandem mass spectrometry on digested oligonucleotides formed by chemically or enzymatically cleaving a ribonucleic acid; scoring candidate sequences; among candidate sequences showing the highest scores, referring those showing scores exceeding the threshold as identified sequences; and using these identified sequences in mapping on nucleic acid sequence database including genomic sequences.

An electric power conversion apparatus comprises: three conversion units; a backup conversion unit that can be substituted for any one of the conversion units; and a backup terminal conductor unit. The conversion units, which are mounted on a converter board disposed in a case, can convert a DC current to a three-phase AC current having U-, V- and W-phases. If any one of the conversion units goes out of order, the backup terminal conductor unit can then electrically connect the auxiliary conversion unit, in substitution for the conversion unit having gone out of order, to a three-phase AC input/output unit.

In fuel supply system for an engine in which a discharge port in a fuel pump driven by the engine to draw up fuel in a fuel tank is connected to an inlet port which is provided in a fuel reservoir and which is controlled in opening and closing by a float valve so that the fuel in the fuel reservoir is supplied to the engine, a second discharge port is provided in the fuel pump, and a second inlet port without a float valve is provided in the fuel reservoir. The second discharge port and the second inlet port are connected to each other through a control valve opened during starting of the engine. Thus, when the engine is started, fuel vapor generated in a pump chamber in the fuel pump can be discharged to the fuel reservoir having an air vent, to normalize the function of the fuel pump, leading to an enhancement in hot startability of the engine.

A system detecting leakage of an internal combustion engine having a secondary air passage, bypassing a throttle valve, at an air intake pipe connecting to the intake manifold and a secondary air control valve which regulates opening of the secondary air passage. In the system, when the changes in the absolute manifold pressure and the atmospheric pressure before and after the engine starts rotation, are small, it is determined that the intake manifold may possibly leak and should be monitored. Specifically, the opening of the secondary air passage is changed and the changes in the pressure, etc., before and after the opening is changed, are calculated and based thereon, it is determined whether the intake manifold, in fact, leaks. With this, it becomes possible to detect intake manifold leakage accurately with a simple configuration.
