20120275383 | RADIO COMMUNICATION APPARATUS AND RADIO COMMUNICATION METHOD - A radio communication apparatus mounted on a mobile body establishes a local network using terminals and relays a packet transmitted and received between a predetermined terminal connected to the local network and a server connected to an external network, which is another network. The radio communication apparatus includes an uplink-traffic monitoring unit and a downlink-traffic monitoring unit to extract header information from packets received from the server and the terminal, a policy table that registers policy information indicating possibility of communication connection establishment for each combination of the server and the terminal and a priority degree of the communication connection, a priority-degree determining unit to determine whether relay processing for the packet is performed, and an uplink-traffic control unit and a downlink-traffic control unit to discard the received packet when the priority-degree determining unit determines that the relay processing is not performed. | 11-01-2012 |
20140167979 | SMART METER SYSTEM, MANAGEMENT ROUTER, AND METER - Management routers perform control for performing a prefix information delegation request for requesting a management server to delegate the management of prefix information, receiving, as a response to the prefix information delegation request, prefix information management delegation from the management server, and delegating the management of the prefix information within a range of management delegation from the management server in response to a prefix information delegation request from meters. The meters perform control for transmitting a prefix information delegation request to the management routers, receiving prefix information management delegation from the management routers as a response to the prefix information delegation request, and notifying a home apparatus in a home network connected to the meters of the prefix information, the management of which is delegated from the management routers. | 06-19-2014 |

20090035577 | Surface-conditioning composition, method for production thereof, and surface conditioning method - A surface-conditioning composition which has a higher chemical conversion treatment capability (can form a denser phosphate coating film on the surface of a metal material) compared to a conventional one, can reduce the electrolytic corrosion of an aluminum-type metal material during a chemical conversion treatment, form a chemical conversion coating film having a satisfactory coating weight even when applied to a hardly convertible metal material (e.g., an aluminum alloy, a high tensile strength steel plate), improve the productivity rate of the chemical conversion treatment, resulting in the reduction of the time required for the chemical conversion treatment, and enables stable dispersion in a surface-conditioning solution for a long period of time. This composition includes a particle of a phosphate of a bivalent or trivalent metal and has a pH value ranging from 3 to 12. The particle has a D | 02-05-2009 |
20110180248 | Method for Surface Treating a Heat Exchanger, Hydrophilizing Treatment Agent, and Aluminum Heat Exchanger - A method for surface treating a heat exchanger, a hydrophilizing treatment agent used in this method, and an aluminum heat exchanger obtained from this method are provided that excel in the initial adherence, hydrophilicity, and odor suppressibility, and can maintain these abilities for an extended time, while having little burden on the environment and the human body. The method for surface treating an aluminum heat exchanger that is brazed includes (1) a pickling treatment step; (2) a chemical conversion treatment step; and (3) a hydrophilization treatment step, in which the acidic cleaning agent contains nitric acid and sulfuric acid and contains ferric salt in a predetermined amount, the hydrophilizing treatment agent contains silica grains coated with a vinyl alcohol polymer and a polyallylamine resin. | 07-28-2011 |
20110180249 | METHOD FOR SURFACE TREATING A HEAT EXCHANGER, SURFACE TREATMENT AGENT, AND ALUMINUM HEAT EXCHANGER - A method for surface treating a heat exchanger and an aluminum heat exchanger obtained from this method are provided that can effectively suppress the foul odor characteristic to flux that emanates following degradation of a hydrophilic coating film and a chemical conversion coating film in a non-corrosive flux brazed heat exchanger on which flux easily remains. The method for surface treating a non-corrosive flux brazed heat exchanger made of an aluminum material conducts a pickling treatment step, a chemical conversion treatment step, and a deodorizing treatment step on the heat exchanger, in which the acidic cleaning agent contains nitric acid and sulfuric acid as well as a predetermined amount of ferric salt, and the surface treatment agent contains silica grains coated by a vinyl alcohol polymer and polyallylamine resin such that the total content of the silica grains and the vinyl alcohol polymer is a predetermined amount. | 07-28-2011 |
20140332397 | BATH FOR SURFACE TREATMENT, METHOD OF PRODUCING SURFACE-TREATED STEEL PLATE BY USING THE BATH FOR SURFACE TREATMENT, AND SURFACE-TREATED STEEL PLATE PRODUCED BY THE SAME METHOD - To provide a bath for surface treatment capable of forming a surface-treating film having excellent corrosion resistance by a high-speed electrolytic treatment, and a method of producing a surface-treated steel plate having excellent corrosion resistance and closely adhering property to the coating maintaining good productivity. A bath for surface treatment used for forming a surface-treating film on the surface of a steel plate by cathodic electrolysis, the bath for surface treatment containing Zr and/or Ti, and a polycarboxylic acid. | 11-13-2014 |
20140377581 | SURFACE TREATMENT AGENT COMPOSITION FOR TIN-PLATED STEEL, AND TIN-PLATED STEEL SUBJECTED TO SURFACE TREATMENT - A surface treatment agent composition which contains aluminum as the coating film formation component and exhibits excellent properties for removing tin ions within a treatment bath when subjecting a tin-plated steel to electrolytic surface treatment, thereby forming a coating film exhibiting excellent corrosion resistance and yellowing resistance. This surface treatment agent composition is used for subjecting a tin-plated steel or a tin-based alloy-plated steel to electrolytic surface treatment and contains aluminum ions, fluorine ions, and polycarboxylic acid. The tin ions that eluted from the tin-plated steel are precipitated within and removed from the treatment bath by using this surface treatment agent composition. | 12-25-2014 |

20090072003 | STAPLER - In order to provide a stapler in which a large volume of paper can be fastened together with a small magnitude of force in a stable fashion, there is provided a stapler | 03-19-2009 |
20090152318 | STAPLER - A flat-type stapler is provided which can fasten a large number of sheets of paper with a small force and in a smooth fashion. The stapler includes a base portion, a magazine portion, a push-down member, handle supporting members, and a handle portion. The handle portion causes the push-down portion to descend by virtue of the principle of the lever with the handle shaft made to act as a movable fulcrum. A portion of the handle may be used to apply force, and the connecting shaft may be used as a point of action. | 06-18-2009 |
20130190156 | FASTENING TOOL - A fastening tool can be held by a single hand and can obviate the necessity of application of strong force when fastening sheets of paper together. The fastening tool has a construction in which a placing table configured to move only in a vertical direction is provided at an inner upper portion of a base member, a paper holding member configured to move in a vertical direction is disposed above the placing table, a handle member is mounted on the base member so as to rotate relative thereto about a position lying near a rear end thereof, and a portion of the handle member which lies inside and further rearwards than a central portion of the handle member is formed into a pressing portion, whereby an upper surface of a rear portion of the paper holding member is pressed down directly by the pressing portion. | 07-25-2013 |
