摘要:
First, to decrease an amount of emitted nitrogen oxides to zero as much as possible and also decrease an amount of emitted carbon monoxide to a permissible level. Second, to save energy on combustion at a low air ratio close to 1.0. Third, to attain a stable air ratio control in a low air ratio combustion region.Included are a combustion step in which hydrocarbon-containing fuel is burned by the burner to generate gas free of hydrocarbons but containing oxygen, nitrogen oxides and carbon monoxide, an endothermic step in which endothermic device is used to absorb heat from gas generated in the combustion step, a hazardous-substance decreasing step in which the gas is brought into contact with an oxidation catalyst after the endothermic step to oxidize carbon monoxide contained in the gas by oxygen and reduce nitrogen oxides by carbon monoxide, and a concentration ratio adjusting step in which a concentration ratio of oxygen, nitrogen oxides and carbon monoxide in gas on the primary side of the oxidation catalyst is adjusted to a predetermined concentration ratio on the basis of concentration ratio characteristics of the burner and the endothermic device by using the air-ratio adjusting device of the burner.

A video receiving system has one main-contract video receiver and at least one sub-contract video receiver connected to the main-contract video receiver via a network.The sub-contract video receiver has a) a video reception control unit which, when a video reception tuner unit receives a video signal, allows the video reception tuner unit to receive the video signal of a limited predetermined channel if a network connection detecting unit detects an unestablished connection with the main-contract video receiver; and b) a display signal output unit which outputs a display signal corresponding to the video signal received by the video reception tuner unit.
摘要:
Provided is a hydrogen generator which is capable of reducing a size of an entire apparatus and reducing a running cost by utilizing heat of a heat exchanger (1) for hydrogen reforming in a reformer (2), and which can particularly preferably be used in a facility such as a hospital, a restaurant, or a hotel utilizing both steam and electricity, and a fuel cell system using the hydrogen generator. The hydrogen generator includes the reformer (2) for generating hydrogen H2 from a fuel gas G and steam H2O incorporated in a fuel gas passage (12) of the heat exchanger (1) provided with a water pipe (13). The hydrogen generator utilizes a part of heat of the heat exchanger (1) for hydrogen reforming performed in the reformer (2). The hydrogen generator includes the reformer (2), a converter (3) for generating hydrogen from carbon monoxide generated in the reformer and steam, and a CO remover (4) for removing a carbon monoxide gas generated in the converter (3). The reformer (2), the converter (3), and the CO remover (4) are arranged in the flue gas passage (12) of the heat exchanger (1).

A communication system includes communication devices; a switch device having coaxial terminal units to which the communication device are connected, a switch unit of entirely or individually connecting the coaxial terminal units, and a switch control unit of controlling the connection status of the switch unit; and a transmittal right control device. The transmittal right control device is connected to the terminal, and manages the connection status of the switch unit, receives from the communication devices requests for time for communication with other communication devices, determines assignment of time for communications between the communication devices, notifies the communication devices of the assignment, and instructs the switch control unit not to make signals interfere among the communication devices in different combinations for communications in the same time period.
摘要:
An object of the present invention is to determine novel means of activating plants; more particularly, means or controlling plant growth, such as means of promoting growth, means of controlling dormancy, means of imparting tolerance against stress for plants (dryness, high or low temperatures, osmotic pressure, etc.), and means of preventing aging.
