  • Publication number: 20200077397
    Abstract: A base station holds information on uplink radio resources which has been allocated to at least one already connected communication terminal for performing radio communication using a high frequency with the base station, receives a notification of participation in a radio communication system from a new communication terminal, and allocates unallocated uplink radio resources using high frequencies to the new communication terminal based on the information on the uplink radio resources when received the notification of participation. The new communication terminal transmits data to the base station by using the allocated uplink radio resources.

  • Publication number: 20200067609
    Abstract: A wireless receiver measures a reception parameter while scanning multiple pieces of reception directivity for an interval during which a signal is not transmitted from a wireless transmitter. The wireless transmitter transmits a signal while scanning multiple pieces of transmission directivity, and the wireless receives measures a reception parameter relating to reception of the signal and determines k pieces of transmission directivity that correspond to high-ranking k results, respectively, of the measurement that have a great reception parameter. The wireless transmitter forms any transmission directivity and transmits a signal, and the wireless receives measures a reception parameter while scanning M pieces of reception directivity and determines reception directivity that is to be used for data communication.

  • Publication number: 20190338773
    Abstract: An object of the present invention is to provide a rotary displacement compressor capable of determining whether a check valve has failed, and preventing the life of a compressor body from being reduced when a compression operation stops. In order to achieve the object, a rotary displacement compressor includes a compressor body that compresses a medium by reducing a volume of the medium using rotation; a discharge pipe through which a compressed medium, which is discharged through a discharge port of the compressor body, flows; a check valve that shuts off the compressed medium flowing backward to the compressor body; and a backflow control valve that allows a predetermined rate of the compressed medium to flow backward. The check valve and the backflow control valve are disposed in series via the discharge pipe.

  • Patent number: 7654396
    Abstract: A classifier capable of stably providing particles by further reducing the mixing ratio of coarse particles including a rotating fin (21) classifying solid particles by a centrifugal force, a cylindrical downward flow forming member (13) installed on the outer peripheral side of the rotating fin (21), a recovery cone (11) disposed under the rotating fin (21) and the downward flow forming member (13), and a housing (41). A contraction flow area (16) is formed between the housing (41) and the recovery cone (11), and a two-phase flow (52) formed of the mixture of the solid particles and gases blown up through the contraction flow area (16) is collided with the downward flow forming member (13) on the upper side of the housing (41) to form it in a downward flow. Then, that flow is led to the rotating fin side, classified into the fine particles and the coarse particles, and the fine particles are carried together with an airstream, passed through the rotating fin (21), and removed.

  • Patent number: 6976440
    Abstract: A fuel supply duct, which supplies a mixed fluid of a solid fuel and carrier gas to one or more burners provided on the walls of a furnace, is provided with a branching part, and each of a plurality of branch ducts, which branch out from the branching part, is connected to a corresponding burner. Also a damper, with which the tilt angle with respect to the direction of flow of the mixed fluid can be changed, is positioned in the fuel supply duct at the upstream side of the branching part so that a mutual difference will arise in the solid fuel concentrations of the mixed fluid supplied to the respective branch ducts. A fuel distributor for fuel supply duct is thus arranged. The tilt angle of the above-mentioned damper is adjusted to increase the concentration of solid fuel in the mixed fluid supplied to a specific burner. At a burner to which the high solid fuel concentration is supplied, stability of ignition and stable combustion of the ignited flame can be obtained during low load operation.
