Title: Gel filtration of factor viii
Inventor: UIRIAMU JIEI BUROTSUKUUEI
IPC: A61K38/43
Filed: 1988-12-16
Abstract: PURPOSE: To prepare a concentrate of a highly specific active antihemophilic factor(AHF) without containing a nonhuman protein by dissolving a low- temperature precipitate and successively carrying out the treatment with a PEG, viral inactivating treatment and gel filtration. CONSTITUTION: A low-temperature precipitate is recovered from a thawed pool of a fresh frozen human blood plasma by the centrifugation and water for injection(WFI) is added thereto and dissolved therein. Aluminum hydroxide is then added thereto to adsorb a vitamin K-dependent factor thereon. A polyethylene glycol(PEG) is added at 20-25 deg.C to precipitate and remove a nonAHF protein. A mixture of glycine with NaCl is added to an eluate containing the AHF to precipitate the AHF. The resultant AHF is further dissolved and viruses are inactivated by treatment with a chemical and the prepared solution is then passed through a filtration column containing a size exclusion resin to remove the chemical. The AHF is isolated to at least 35 units of factor VIII activities based on 1mL pooled concentrate.

Abstract: PURPOSE:To obtain a developing device provided with a means for effectively removing toner fixed in a developing device by heat by providing a fixed toner removing member capable of sliding between a developing roller and a developing blade. CONSTITUTION:When a toner cartridge 1 is set in a state where a shutter 2 is closed, at the beginning, the fixed toner removing member 8 is moved with the shutter 2 and positioned on the deepest side of the developing roller 7 and the developing blade 6. Thereafter, by pulling out the shutter 2 so that the inside toner may be moved in a hopper, the member 8 is moved to the frontest side of the roller 7 and the blade 6. When the shutter 2 is moved back and forth, the toner fixed to the blade 6 is removed. Therefore, an operator removes the toner fixed to the blade 6 by nearly the same operation as ordinary operation in the case of setting the toner cartridge 1 in the developing device.

Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent the rejection of a new connection requesting signal from a mobile station due to the abnormal condition of a call management memory. SOLUTION: A call management memory 141 stores a calling mobile station identification number on one calling number and connection request accepting date and time from a timer means 133 in such a state that the call number is arranged as a subscript. When a communication control means 131 assigns a call, the means 131 checks whether or not the calling mobile station identification number of a connection requesting signal is registered in the memory 141 and, when the number is registered in the memory 141, refers to the connection request accepting date and time. When the value obtained by subtracting the present time from the registered time exceeds a value specified in the service specification of a system, the means 131 newly registers the call by deleting the relevant call.  When the time specified in the service specification elapses after an abnormal condition occurs in the memory 141, connection requesting signals from the same mobile station become acceptable.
