摘要:
The present invention provides a device for biological wastewater treatment which prevents flotation and deformation of mesh tubes packed in a reactor tank as microorganism retaining materials. Device for biological water treatment 10 of the present invention comprises reactor tank 11; microorganism retaining media 12, which are installed in the tank; and air diffuser tubes 14, and wastewater distributor tube 16, both of which are installed under the microorganism retaining media. The microorganism retaining media comprise supporting media 22 and mesh tubes 24, which are installed on the supporting media. The supporting media are constituted in a manner that at least two the beams 26 are arranged on each supporting tier in parallel at certain intervals and the direction of the arrangement of the beams is alternately shifted by an angle of 90 degrees at every supporting tier. Also, the supporting tiers are piled in a manner that a space between two adjacent supporting tiers is enough for arranging mesh tubes on a supporting tier. The mesh tubes on each supporting tier are supported by beams of said supporting tier and arranged in parallel with beams on the adjacent tier.

Powders of respective metal elements (Mn,Co) constituting a transition metal oxide (MnCo2O4) having a spinel type crystal structure are used as a starting material. A paste containing the mixture of the powders is interposed between an air electrode and an interconnector, and with this state, a sintering is performed, whereby a bonding agent according to the present invention can be obtained. This bonding agent has a “co-continuous structure”. In the “co-continuous structure”, a thickness of an arm portion that links many base portions to one another is 0.3 to 2.5 μm. The bonding agent includes a spherical particle in which plural crystal faces are exposed to the surface, the particle having a side with a length of 1 μm or more, among the plural sides constituting the outline of the crystal face. The diameter of the particle is 5 to 80 μm.

The present invention provides an electrochemical device including electrodes of an electrochemical cell and conductive connection members, wherein sufficient bonding strength is achieved between each of the electrodes and the corresponding conductive connection member through thermal treatment carried out at a temperature lower than 1,000° C. The electrochemical cell includes a solid electrolyte membrane and a pair of electrodes provided on the electrolyte membrane. The conductive connection members are electrically connected to the respective electrodes by means of a bonding layer. The bonding layer contains a transition metal oxide having a spinel-type crystal structure.

An electric current supply control apparatus for a glow plug, and glow plug and the electric current supply control apparatus connected to the glow plug. In a transition state in which the load acting on an engine increases such as at the time of acceleration (S14: YES), an instruction signal which instructs increasing of an EGR amount is transmitted to an ECU (S18). Further, electric current is supplied to a heat generation resistor of a glow plug through resistance PI control (S20), whereby the temperature of the heat generation resistor is stably maintained at a target temperature, and stability of combustion is enhanced. Thus, even at the time of acceleration, generation of NOX can be suppressed effectively by increasing the EGR amount without lowering the engine output.

A safety master configured to communicate with a plurality of safety slaves over a safety field network or with a plurality of safety local I/O units connected by a safety back plane bus of the safety master, wherein each of the plurality of safety slaves and safety local I/O units allow connection to safety I/O devices in a plurality of cell equipment, and wherein the safety master receives a status signal indicating a “safe state” or an “unsafe state” related to cell equipment from each of the corresponding plurality of safety slaves or safety local I/O units, and controls operation/stop of cell equipment by executing an interlock operation program with the received status signal as an input to output an operation instruction signal.
摘要:
A risk evaluation support device is used for a safety network which serves to cause an output device to make a controlled device operable based on a detection signal outputted from an input device when the input device detects a safety condition. The support device creates a parameter setting table for correlating a danger source with the input and output devices and a PLC for risk evaluation based on configuration data of the safety network obtained through a communication part and device data on devices obtained from a component database. Operating data for the safety network are obtained according to conditions provided by the parameter setting table and a current risk evaluation value for the danger source is calculated based on the obtained operating data. The calculated risk evaluation value is outputted to a display part.

A selectively permeable membrane reactor includes a reaction tube including a supply port as an inlet port for a raw material gas and a discharge port as an outlet port for an unseparated gas, and a separation tube inserted into the reaction tube. The separation tube includes a selectively permeable membrane exhibiting selective permeability for a specific component on a surface facing the internal space of the reaction tube, and a process port as an outlet port for a separated gas which has passed through the selectively permeable membrane, and a catalyst for promoting a chemical reaction is provided in the reaction tube excluding the separation tube. A catalyst is carried by a foamed body having porous structure to form a foam-molded product and suppresses physical and chemical deterioration in the selectively permeable membrane and allows a mixed gas produced by a catalytic reaction to be efficiently separated.
