20100068088 | HOT BRIQUETTE IRON AND METHOD FOR PRODUCING THE SAME - Hot briquette iron includes a plurality of reduced iron particles which are bonded to each other by hot forming, wherein the reduced iron particles each have a surface region having an average carbon content of 0.1 to 2.5% by mass and a central region positioned inside the surface region and having an average carbon content higher than that of the surface region. | 03-18-2010 |
20110265603 | METHOD FOR PRODUCING GRANULAR IRON - A method for producing granular iron comprising: charging agglomerates formed from a raw material mixture containing an iron oxide-containing substance and a carbonaceous reducing agent onto a carbonaceous material spread on a hearth of a furnace; and heating the agglomerates to thereby reduce and melt iron oxides in the agglomerates, wherein the temperature of the agglomerates in the furnace is set in a range between 1200° C. and 1500° C.; the oxygen partial pressure in atmospheric gas under which the agglomerates are heated is set to 2.0×10 | 11-03-2011 |
20120103136 | APPARATUS AND METHOD FOR PRODUCING REDUCED IRON FROM ALKALI-CONTAINING IRONMAKING DUST SERVING AS MATERIAL - Provided is a movable hearth furnace for thoroughly removing alkali metal elements and producing high-strength reduced iron when producing reduced iron using iron production dust containing alkali metal elements in a movable hearth furnace. The movable hearth furnace comprises: a reduction zone for heating and reducing a carbon composite briquette (C) to produce a reduced briquette (D) having an iron metallization rate of 80% or greater; an alkali removal zone, disposed after the reduction zone, for heating the reduced briquette in a reducing atmosphere and removing the alkali metal elements from the reduced briquette to obtain an alkali-free reduced briquette; and a strengthening zone, disposed after the alkali removal zone, for heating the alkali-free reduced briquette in an oxidizing atmosphere and raising the crushing strength of the alkali-free reduced briquette to produce reduced iron product. | 05-03-2012 |
20130201976 | COMMUNICATION SYSTEM AND TRANSMISSION UNIT - A signal transceiving section transmits a transmission signal to a transmission path, each frame in the transmission signal is divided into a plurality of periods in a time axis direction, and the plurality of periods includes superimposing period for superimposing a superimposed signal. A transmission unit includes a signal adjustment section for changing the proportion of the superimposing period in one frame of the transmission signal. The signal adjustment section adjusts the proportion of the superimposing period in accordance with a transmission state of the superimposed signal transmitted between second communication terminals. The signal adjustment section may adjust the proportion of the superimposing period so that the proportion of the superimposing period in one frame of the transmission signal increase with increasing the volume of transmission data transmitted between the second communication terminals through the superimposed signal. | 08-08-2013 |
20130208733 | COMMUNICATION SYSTEM AND SUPERIMPOSING APPARATUS - The communication system includes: first terminal devices connected to a transmission path and having terminal information; a second terminal device connected to the path and sending an information request requesting the information from the first terminal device; a first superimposing apparatus interposed between the first terminal device and the path; and a second superimposing apparatus interposed between the second terminal device and the path and receiving the request from the second terminal device. The first superimposing apparatus acquires the information from the connected first terminal device at predetermined timings and stores it. Upon receiving the request, the second superimposing apparatus sends the request to the first superimposing apparatus using a superimposed signal superimposed on a transmission signal transmitted via the path. Upon receiving the request, the first superimposing apparatus sends the information to the second superimposing apparatus using the superimposed signal. Upon receiving the information, the second superimposing apparatus provides the information to the second terminal device. | 08-15-2013 |
20130250846 | RELAY DEVICE - The relay device includes a first switch interposed between a first extraction unit and a second superimposing unit and a second switch interposed between a second extraction unit and a first superimposing unit. The first switch opens and closes a path where a superimposed signal is relayed from a first transmission path to a second transmission path. The second switch opens and closes a path where a superimposed signal is relayed from the second transmission path to the first transmission path. The first switch is controlled in response to reception of a first control signal to be turned off when a superimposed signal is relayed from the second transmission path to the first transmission path. The second switch is controlled in response to reception of a second control signal to be turned off when a superimposed signal is relayed from the first transmission path to the second transmission path. | 09-26-2013 |
20140088775 | APPARATUS CONTROL SYSTEM, MOBILE TERMINAL AND PROGRAM - Apparatus control system includes control device controlling operation of apparatuses and portable mobile terminal communicable with the control device. In the control device, control unit controls each apparatus in accordance with control schedule stored in device-side storage unit and control request from the mobile terminal. In the mobile terminal, date and time setting unit sets arbitrary date and time as set date and time. Terminal-side storage unit stores terminal-side schedule in which control contents are associated with control dates and times for each apparatus. Simulation unit simulates operating state of each apparatus assuming that the apparatus is operating at the set date and time set by the date and time setting unit, using the terminal-side schedule. Apparatus state reflection unit outputs control request to the control device to cause the control device to control each apparatus such that the apparatus is in the operating state simulated by the simulation unit. | 03-27-2014 |
