  • Publication number: 20100300948
    Abstract: According to one embodiment, water to be treated is passed through each of a first reactor vessel and second reactor vessel, phosphorus contained in the water is removed by using an adsorbent, thereafter the liquid held in each of the reactor vessels is discharged from each of a first treated water discharge path and second treated water discharge path, and thus the influence of soluble impurities derived from the water is eliminated. Further, when suspended solids impurities contained in the water are accumulated in the phosphorus adsorbent, the accumulated impurities are eliminated by a reverse cleaning operation using a liquid to be thereafter introduced from a reactor vessel liquid introduction path into the reactor vessel, and hence the influence of the suspended solids in the water on a desorption agent liquid to be thereafter introduced into a crystallization vessel, and containing phosphorus from the phosphorus adsorbent is eliminated.

  • Patent number: 7704385
    Abstract: An aeration-less water treatment system includes an anaerobic treatment tank which subjects sewage supplied by a pump to anaerobic treatment by causing the sewage to upflow, and an aerobic treatment tank which subjects anaerobically treated water to aerobic treatment by letting the anaerobically treated water to downflow by natural downflow. The aerobic treatment tank includes an aerobic filter bed section in which carriers to which aerobic microorganisms are adhered are arranged. The aerobic filter bed section subjects the anaerobically treated water to decomposition treatment by putting the anaerobic treatment water in contact with the aerobic microorganisms adhered to surfaces of the carriers. The aerobic filter bed section is provided with an air port which takes in air into under normal pressure, thereby activating the aerobic microorganisms.

  • Patent number: 7688799
    Abstract: In a case of being judged that a compressed mode is applied in a mobile terminal, if it is judged that reception quality during data communication is favorable, gap intervals are not created by passing through a processing of gap interval creation. Further, if the data communication over the HS-DSCH is performed, the data communication over the HS-DSCH is continued. This prevents degradation of data transmission rate over a channel for high speed data transmission service, in the presence of a mobile terminal in a favorable reception quality area.

  • Patent number: 7619976
    Abstract: When retransmission requests are issued based on the results of error-correction decoding of received data packets to perform data transmission, statistical information indicating whether received data packets have been successfully decoded or have not been decoded is acquired, and based on the rate at which correct decoding has been made or the rate at which correct decoding has not been made, which is obtained from the statistical information, a request is transmitted to the transmission source to change the window size, which is the number of data units handled in a predetermined layer, so that when for example the communication environment is not excellent, processing can be performed at a small window size, and the occurrence of circumstances in which data retransmission and the discarding of received data are repeated can be efficiently prevented.

  • Publication number: 20080299301
    Abstract: The present invention discloses a method for processing a substrate on which transparent electrode made of metal oxide is formed before forming an organic EL element on the transparent electrode. According to the method, the substrate is accommodated in a bake chamber provided with a heater. The substrate is heated while mixed gas of oxygen and nitrogen is introduced into the bake chamber so as to replace the gas in the bake chamber. The mixed gas is introduced into the bake chamber in an amount that is 1/60 or more and 1/15 or less of a whole volume of the bake chamber per minute. According to this method, moisture is removed and an appropriate surface treatment is performed for the transparent electrode of metal oxide at the same time.
