20120079266 | COMMUNICATION SYSTEM, COMMUNICATION DEVICE, AND COMMUNICATION METHOD - A first communication device includes a security policy storing unit that store a security policy and a default policy applied to communication to which the security policy is not applied, a communication unit that performs communication, and a communication control unit that performs an encryption process and a decryption process according to the default policy when the communication does not correspond to the target of the policy. A second communication device includes an input and output receiving processing unit that receives an input of an encryption key of the default policy of the first communication device, a communication control unit that generates a policy including an encryption method of the default policy and the input encryption key and performs an encryption process and a decryption process in communication with the first communication device according to the policy, and a communication unit that performs communication of a communication packet. | 03-29-2012 |
20120166608 | NETWORK COMMUNICATION METHOD, NETWORK COMMUNICATION SYSTEM, NETWORK COMMUNICATION APPARATUS AND PROGRAM THEREFOR - A method for network communication under SNMP includes: producing an access request when a first device accesses management information stored in a second device, the request containing additional information including identification information of the first device or identification information of a user of the first device in a value field included in a data field that contains an identifier field and the value field; transmitting the access request to the second device; and permitting the transmitted access request so that the number of devices or users accessing the second device may not exceed a predetermined number on the basis of the identification information of the first device or the user contained in the transmitted access request and identification information of a device or a user accessing the management information. | 06-28-2012 |
20120216033 | COMMUNICATION SYSTEM, PRINTING DEVICE, AND SA ESTABLISHMENT METHOD - A communication system includes an SA parameter exchanging portion that builds and deletes SA, and a nonvolatile storage portion that stores at least a part of information for the SA parameter set, wherein, in a case where a printing device is initialized, the printing device has a message transmission portion that transmits a predetermined message to a communication device if a part of information is stored in a nonvolatile storage portion, and the communication device deletes information for performing IPsec communication with the printing device from a nonvolatile storage portion of the communication device in response to reception of the predetermined message. | 08-23-2012 |

20150218476 | INDIRECT HEAT DRYING METHOD FOR PARTICULATE MATTER, REFINED-COAL PRODUCTION METHOD, INDIRECT HEAT DRYING DEVICE, AND REFINED-COAL PRODUCTION DEVICE - The purpose of the present invention is to provide an indirect heat drying method and a refined-coal production method, with which the stability of carrier-gas pressure balance can be improved when using indirect heat dryers to dry particulate matter. This indirect heat drying method for particulate matter uses two indirect heat dryers, and is provided with: a step (A) in which particulate matter is dried in a first indirect heat dryer; and a step (B) in which the particulate matter is further dried in a second indirect heat dryer to obtain dried particulate matter. The indirect heat drying method for particulate matter is characterized by being further provided with a step (C) in which first microparticles included in a carrier gas discharged from the first indirect heat dryer are recovered and mixed with the particulate matter supplied to step (B); and a step (D) in which second microparticles included in a carrier gas discharged from the second indirect heat dryer are recovered and mixed with the dried particulate matter obtained in step (B). | 08-06-2015 |
20150240178 | METHOD FOR STORING UPGRADED COAL, AND GRAIN-SIZE-CONTROLLED COAL - A method for storing upgraded coal, which is economical and whereby it becomes possible to prevent the spontaneous ignition of piles; and grain-size-controlled coal which rarely undergoes spontaneous ignition during storage. The method for storing upgraded coal includes piling up granular coal containing upgraded coal, wherein the content of grains each having a grain size of 10 mm or less in the coal is 50 mass % or more. It is preferred that the content of grains each having a grain size of 1 mm or less is 25 mass % or more and the content of grains each having a grain size of 0.15 mm or less is 7 mass % or more in the coal. | 08-27-2015 |
20150376529 | METHOD FOR PRODUCING MOLDED SOLID FUEL - A method of manufacturing a molded solid fuel including: a pulverization for pulverizing low-grade coal; a mixing for obtaining a slurry by mixing the pulverized low-grade coal and a solvent oil; a dehydration for obtaining a dehydrated slurry by heating and dehydrating the slurry; a solid-liquid separation for obtaining a cake by separating the solvent oil from the dehydrated slurry; a drying for obtaining powdery modified coal by heating the cake and further separating the solvent oil from the cake; and a molding for pressurizing and molding the powdery modified coal by using a molding machine, without the addition/mixture of a binder. In the molding, a coolant is sprayed onto the surface of the molding machine, and the surface temperature of the molding machine is kept equal to or below 100° C. | 12-31-2015 |
20160002552 | METHOD FOR PRODUCING MOLDED SOLID FUEL - A method for producing a briquetted solid fuel includes pulverizing a low-rank coal. The pulverized low-rank coal is mixed with a solvent oil to give a slurry. The slurry is heated and dewatered to give a dewatered slurry. The solvent oil is separated from the dewatered slurry to give a cake. The cake is heated to further separate the solvent oil from the cake to thereby give a refined coal in powder form. The refined coal is combined with a property-controlling coal in powder form having, as properties, a loose bulk density of 0.6 kg/L or more and an angle of repose of 40° or less, to give a briquetting feedstock containing the property-controlling coal in an amount of 5 to 70 mass percent based on the total mass of the briquetting feedstock. The briquetting feedstock is briquetted under pressure to give the briquetted solid fuel in briquette form. | 01-07-2016 |
