Abstract: A sheet folding apparatus includes a conveyor, a first folding roller, a second folding roller, a third folding roller, a guide, a motor, and a driving force transmission mechanism. The motor causes the second folding roller to perform either forward rotation in which the second folding roller rotates to convey a sheet on a main conveying path in a conveying direction and to convey the sheet on a reflux conveying path from a joining position toward a branching position or backward rotation in a direction opposite to the forward rotation. The driving force transmission mechanism rotates the guide toward a first posture from a second posture in conjunction with the forward rotation of the second folding roller and rotates the guide from the first posture toward the second posture in conjunction with the backward rotation of the second folding roller.

Abstract: A plant effluent treatment method includes a mixing treatment step that mixes a microorganism activating agent into plant effluent containing organic compounds as discharged from a chemical plant, petroleum plant or petrochemical plant and discharges it as mixing treatment effluent, and an aerobic treatment step that subjects the mixing treatment effluent to aerobic biological treatment and solid-liquid separation treatment in a membrane bioreactor tank.

Abstract: Antenna verification is controlled in the ON state at least until transmission to a wireless base station is started, and particularly, a result of estimation of the signal phase individually from two antennas of the wireless base station is reflected on a reception signal process, to decrease the failure rate in synchronism establishment arising from that antenna verification of transmission diversity to be carried out for reception characteristic enhancement of the downlink is controlled in the OFF state in order to enhance the throughput characteristic as in a case wherein the HSDPA is applied.

Abstract: A method of radio communication in a radio communication system including a plurality of mobile terminals and a base transceiver station. The method includes establishing radio communication between a first mobile terminal and the base transceiver station by using a first physical channel and a first dedicated channel, wherein a slot of the first physical channel is shared by time-division multiplexing by first and second control information, the first control information being for the first dedicated channel of the first mobile terminal, the second control information being for a second dedicated channel of a second mobile terminal, and switching the first physical channel to a second physical channel on the basis of a first communication quality of the established radio communication, wherein a slot of the second physical channel is dedicated to the first control information.

Abstract: To provide a mobile terminal capable of shortening the time required for deciding whether a terminal is located within the range of an area frequency at the time of the terminal power switched on, and securely performing location registration to a cell producing a large electric field intensity by recognizing an area frequency in advance.
