摘要:
A method for cleaning separating membranes uses a uniquely formulated detergent. The detergent includes a percarbonate-containing, material, existing in the condition in which hydrogen peroxide is adducted in carbonate and is desirably an alkali metal salt. The percarbonate decomposes the organisms deposited on the membrane surfaces while being environmentally desirable. The detergent preferably also includes at least one bivalent iron salt, which improves the cleaning capability of the percarbonate via the so-called Fenton's reaction in which hydrogen peroxide adducted in the percarbonate reacts with the iron ions to form OH— radicals which have a very high oxidative reactivity. The detergent may also contain other oxidizers, a surfactant, a chelating agent, an acid and a pH regulator. The detergent is dissolved in water prior to use.

A membrane separator assembly for separating solids from water includes opposing enclosure wall structures, a membrane module unit, and a gas diffuser disposed below the membrane module unit. The membrane module unit includes a plurality of membrane modules respectively having at least one separating membrane extending between at least two membrane fixing members. At least one of the membrane fixing members has a main passage which is in fluid communication with a membrane passageway. The membrane passageway is accessible to water via permeation through the separating membranes and is inaccessible to solids which are impermeable relative to the separating membranes. The membrane separator assembly is preferably used with a detergent containing percarbonate, preferably sodium percarbonate. The assembly also includes a gas diffuser with two opposing main pipes and branch pipes extending therebetween to avoid undesired pressure differentials when cleaning the assembly.

The invention concerns a gas diffuser constructed and arranged to disperse gas into a aeration vessel of a water treatment assembly from a blower. The gas diffuser includes main pipes, branch pipes extending between the main pipes and containing gas discharge ports, wherein the branch pipes have a smaller cross-sectional area than the cross-sectional area of the main pipes. The gas discharge ports are further sized, constructed and arranged to reduce the possibility or likelihood of sludge from blocking the ports or entering the branch pipes. This object is achieved either by placement of the ports on the bottom sides of the branch pipes or, alternatively, by construction of the ports to include conduit members, themselves having an arrangement of openings or coverings to prevent or reduce the likelihood of sludge from blocking the ports or entering the branch pipes.

An embodiment of the present invention includes a fixing member; a pressure member for pressing against the fixing member so as to form a nip region between the pressure member and the fixing member; a pressure cancellation unit for pressing the pressure member against the fixing member and for cancelling the state in which the pressure member is pressed against the fixing member; a paper detachment member for detaching paper held between the fixing member and the pressure member in the nip region from the pressure member; and a separation mechanism for cleaning the paper detachment member by separating the paper detachment member from the pressure member in conjunction with a pressure cancellation operation of the pressure cancellation unit.

A pedometer is provided for use by a pregnant woman. Embodiments include a pedometer having a number-of-activity step acquisition unit that acquires the number of activity steps taken by the pregnant woman, an activity energy consumption calculation unit that calculates activity energy consumption caused by the number of activity steps, and a proper energy consumption storage unit that stores proper energy consumption for the pregnant woman. A comparison and assessment unit compares the activity energy consumption with the corresponding proper energy consumption and assesses the activity energy consumption of the pregnant woman. A comparison and assessment result output unit outputs the result of the comparison and assessment.

On the basis of information of a topology map, a parent node ID list is generated to show correspondence of ID of each node to that of its parent node. Information given by the parent node ID list is transmitted as connection display data in a predetermined format. The receiving side, on the basis of the received connection display data, obtains information of a connecting status display to display connecting status of a network. On the basis of this information, a display to show connecting status of the network is displayed.

A hologram recording material is provided and includes at least a sensitizing dye capable of absorbing light having a hologram recording wavelength to generate an excited state thereof, and an interference fringe-recording component capable of recording interference fringes providing a refractive index modulation by an electron transfer or an energy transfer from the excited state, in which the sensitizing dye in the hologram recording material has a molar absorption coefficient within a range of 1 to 10,000 at the hologram recording wavelength.

A method for transmitting information included in a received packet to an upper layer of a node, including: judging whether or not a first packet satisfies a first condition, storing information which is information in the first packet and used as a part of or all of a second condition when the first packet is judged to satisfy the first condition, judging whether or not a second packet satisfies the second condition when the first packet is judged not to satisfy the first condition, and enabling information in the second packet to be transmitted to the upper layer of a node when the second packet is judged to satisfy the second condition.
