Abstract: PURPOSE:To eliminate carbonization lag quality variation of coke at an inlet part of coke oven and to contrive to reduce drying equipment cost and energy cost, by separately feeding coal having different water content of raw material to the inlet part and a central part of coke oven. CONSTITUTION:Regulated coal 10 which is dried and controlled at both end parts of coal column is fed to both end parts of a coal charging truck divided by partition walls 5 and unregulated coal 11 at the central part of the coal column is fed to the central part of the coal charging truck 4. Then, the regulated coal 10 and the unregulated coal in the coal charging truck 4 are simultaneously discharged and the regulated coal 11 is fed to both inlet parts 7 at the coke sides and the machine sides of the coke oven 6. In the operation, since the regulated coal 10 and the unregulated coal 11 are separated and fed to the coke oven by distributing chutes 8 set at end feed openings 9 of both the inlet parts, the regulated coal 10 is fed in a concentrative way to the inlet part. Consequently, the coke oven 6 is separately charged with the regulated coal with low water content at both the inlet parts 7 and with the unregulated coal 11 at the central part and carbonized in this state.

Title: Packet storage system
Inventor: YOMO YOSHIAKI
IPC: H04L47/43
Filed: 1981-07-17
Abstract: PURPOSE:To prevent different packets from being coupled together, by collating pieces of key information of split and stored packets given at the time of reception when those packets are coupled together. CONSTITUTION:When transferring packets to a CCE (communication controller) by packet transmission, a CPU informs the CCE of key information reported during reception together with addresses of a PM (packet storage memory) wherein the packets to be coupled are stored. A BKC (buffer key control part) collates the key information added to the packet stored in the PM address reported from the CPU with the key information reported from the CPU. When the collation result shows coincidence, the CCE after removing the key information from the packets stored in the PM couples those packets and sends them to a circuit. When they are not coincident, the CPU is instructed to discard the packets.

Title: Magnetically repulsive valve
Inventor: KIMURA MOTOYASU
IPC: F16K31/06
Filed: 1980-08-14
Abstract: PURPOSE: To provide a submersion type valve having a simple structure and capable of being easily processed with corrosion preventive treatment, by utilizing magnetic repulsive force generated between both magnetic poles of a pair of electromagnets which are arranged opposite to each other and which have opposed surface portions, respectively, each magnetic pole being produced on each opposed surface portion by applying electrical current, thereby to open and close the valve.  
     CONSTITUTION: The supply of electrical current to winding 10, 11 through electrical wires 12, 13 generates magnetic force between two electromagnets 1, 3 which are vertically aligned on a base 2. Since both magnets 1, 3 are so arranged that two opposed ion cores 4 are adapted to have the same magnetic poles, they repels together, resulting that the electromagnet 3 which is simply piled on the electromagnet 4, is floatingly raised. Therefore, a rod 5 fixed at the upper end to the electromagnet 3 is pulled up, causing a valve member 8 fixed to the lower end of the rod 5 to be lifted from a valve seat 9 so as to open the valve. Thus, water is discharged from a water tank disposed on a body of a device. In this arrangement, it may possible to mount a float 14 having a predetermined buoyancy for maintaining the open state of the valve member 8, thereby to save electrical power consumed.
