  • Patent number: 8602339
    Abstract: In a vertical mill, a pulverization table is supported with a vertical rotation axis core in a housing so as to be capable of being driven and rotated, and a pulverization roller rotatable in conjunction with rotation of the pulverization table is disposed above the pulverization table so as to be opposed to the pulverization table, and a roller swing mechanism is provided so as to make the pulverization roller parallel to a surface of the pulverization table and swingable in a direction different from a direction of rotation of the pulverization table. Accordingly, a solid matter such as biomass can be efficiently pulverized, thereby achieving improvement in pulverization efficiency.

  • Patent number: 7899908
    Abstract: To provide a distribution request management method and so on in which a communication service providing side can perform data signal distribution while keeping high reliability. A maximum number of distributable requests is set arbitrarily for requests from a mobile communication network 10 to one or plural contents providing servers 31 provided on a communication network 30, the requests being made for distribution of signals including data of contents, and a request management apparatus sends the signal distribution requests to the contents providing servers as long as the number of the requests is within a range not larger than the maximum number of distributable requests.

  • Publication number: 20070289007
    Abstract: [Problem] To obtain an authentication proxy method, a distribution management device to be proxy for authentication, etc. in which a user does not have to be aware of authentication in distribution of contents needing authentication. [Means for Resolution] A distribution management device 22 for managing distribution of signals including data of contents to a mobile communication network 10 determines whether a contents providing server 31 on another communication network 30 has made a transmission request for a signal including authentication data in response to a distribution request for a signal including data of contents which request has been sent from a mobile terminal device 11 through the mobile communication network 10. When it is concluded that the transmission request has been made, the distribution management device 22 creates a signal including the authentication data for the mobile terminal device 11 and transmits the created signal to the contents providing server 31.

  • Patent number: 5603268
    Abstract: A control system of coal pulverizer associated with a rotary classifier, applicable to a pulverized coal burning boiler or the like, includes a function generating section, a computing section, and a rotational speed controlling section. The function generating section receives a signal representing a coal feed rate and outputs signals representing a preset proper range of a current to be fed to the motor of the coal pulverizer for such coal feed rate. The computing section is responsive to a signal representing the current motor current and the signals produced by the function generating section to output a command signal which will maintain the speed of the rotary classifier when the motor current represented by the motor current signal is within the proper range, and to output a command signal which will decrease or increase the speed of the rotary classifier, respectively, in the case where the same motor current has increased or decreased beyond the proper range.
