  • Publication number: 20210277361
    Abstract: The present invention has been made in view of a problem regarding stability, reproducibility, economy, and easiness of operation in studies for a monocyte- or dendritic cell-mediated infectious microorganism, and is directed to provide a method for maintenance culturing a monocyte- or dendritic cell-mediated infectious microorganism utilizing a monocyte having a proliferative capacity. The present invention is based on the finding that a dengue virus efficiently infects a proliferable human monocytic cell obtained by introducing a gene into a CD14-positive cell and a cell having a phagocytic capacity obtained by inducing the monocytic cell to differentiate (e.g., dendritic cell) and proliferates therein. Thus, provided is a novel method for evaluating a pharmaceutical such as a compound or a vaccine for treating an infection with a monocyte- or dendritic cell-mediated infectious microorganism.

  • Patent number: 6652199
    Abstract: A vessel conveying system includes a dryer disposed within a first sterile chamber. If a vessel stays within the dryer for a prolonged length of time, it will be deformed under heat. Accordingly, the vessel is removed by a reject wheel and dropped onto a discharge chute disposed below. A downstream portion of the discharge chute is surrounded by a second sterile chamber, which is separate from the first mentioned sterile chamber, A glove mounted on the wall of the second chamber enables access to the discharge chute while maintaining the chute in a sterile condition. A door is mounted on the wall of the second chamber, and the rejected vessel is discharged through the door. The sterile chambers are disposed within a processing chamber. The pressure within the first chamber is controlled to be higher than the pressure (atmospheric pressure) within the processing chamber and the pressure within the second chamber is controlled to be lower than the atmospheric pressure.

  • Patent number: 5579458
    Abstract: A display control system for a scan type display apparatus in which a display screen is divided into a plurality of split display regions on a video screen and each display region is scanned in parallel. A dual port memory having a random access port and a serial access port is used as a display memory and display data is inputted through the random access port and outputted through the serial access port. Display addresses for reading out sequentially display data corresponding to each raster of every split display region one by one from the dual port memory are generated and the display data of each of the split display regions read out from the dual port memory are stored into each of the buffer memories. The display data stored in the buffer memories is read out and transferred to the scan type display device.

  • Patent number: 4924432
    Abstract: The dot data to be displayed is divided and stored in an even address graphic memory and an odd address graphic memory. When data to be revised (refreshed) bridges over adjacent word units having different addresses, the CPU generates the word address of the odd address graphic memory and new dot data to be displayed. A peripheral control circuit generates the word address signal and an address signal of the adjacent address of the even address graphic memory so as to revise the dot data which bridges over two word addresses. In this way, the dot data which bridges over two addresses can be revised by only one access operation to the memory.
