20130089491 | RAW PETROLEUM COKE COMPOSITION FOR ANODE MATERIAL FOR LITHIUM ION SECONDARY BATTERY - Provided is a raw petroleum coke composition as a raw material of an anode carbon material that can improve, when a battery is discharged at a high current, the ratio capable of maintaining the capacity obtained during discharge at a low current. More specifically, provided is a raw petroleum coke composition for an anode carbon material of a lithium ion secondary battery, the raw petroleum coke composition being produced by subjecting a heavy-oil composition to a delayed coking process, and comprising an atomic ratio of hydrogen atoms H to carbon atoms C(H/C atomic ratio) of 0.30 to 0.50, and a micro-strength of 7 to 17% by weight. Further provided are a method for producing an anode carbon material of a lithium ion secondary battery, comprising the steps of: pulverizing the raw petroleum coke composition into particles having an average particle diameter of 5 to 30 μm, and subjecting the particles to carbonization and/or graphitization; and a lithium ion secondary battery comprising an anode comprising such a carbon material. | 04-11-2013 |

20130139690 | EXHAUST GAS TREATMENT SYSTEM - A mixed gas containing monosilane is released from a semiconductor fabrication equipment. A pump unit suctions the mixed gas discharged from the semiconductor fabrication equipment and sends it out to a silane gas treatment unit provided at a stage subsequent to the pump unit. Argon gas is used as a purge gas of the pump unit. The silane gas treatment unit processes the mixed gas, containing at least hydrogen and monosilane, discharged from the semiconductor fabrication equipment via the pump unit. And the silane gas treatment unit separates and recover monosilane from the mixed gas so as to be recycled. Argon recovered by a noble gas treatment unit is used as the purge gas of the pump unit. | 06-06-2013 |
