Patent number: 8865456Abstract: The present invention provides a nucleic acid collection device that can estimate the nucleic acid collection amount when collecting nucleic acids from a biological sample containing nucleic acids. The nucleic acid collection device comprises a sucking and discharging unit for sucking in and forcing out a sample containing nucleic acids, a collector for collecting the nucleic acids by sucking in and forcing out the sample using the sucking and discharging unit, a pressure measurer for measuring a discharging pressure when forcing out the sample and a sucking pressure when sucking in the sample, and measuring a differential pressure that is the difference between the discharging pressure and the sucking pressure, and an estimator for estimating the collection amount of nucleic acids collected based on the differential pressure.Type: GrantFiled: April 27, 2012Date of Patent: October 21, 2014Assignee: ARKRAY, Inc.Inventors: Masahiro Kozuka, Yukihiro Sukawa

Patent number: 8843602Abstract: In a network boot system, a client terminal is caused to detect a revision of a virtual disk so as to decide operations of a read cache driver. The client terminal has a physical storage device. An operating system operating on the client terminal has a read cache mechanism that read-caches data that has been read out from a boot server. The read cache mechanism includes a filter driver for converting an access to a local bus of the client terminal into an access to the network, and a read cache driver for driving a storage device. The data in the virtual disk is compared with the revision of the read cache data. The operations of the read cache driver are decided based on the comparison result.Type: GrantFiled: May 28, 2009Date of Patent: September 23, 2014Assignee: CO-CONV, Corp.Inventors: Shin Maruyama, Masahiro Kozuka

Patent number: 8433888Abstract: To minimize network access to a server in a network boot system. A server which stores an OS operating on a client terminal and a client terminal which includes a physical storage device are connected to each other over a network. The client terminal includes a physical memory and a network interface, and the OS includes a network driver for driving the network interface, a filter driver for converting access to a local bus of the client terminal into access to the network, and a read cache driver for driving the storage device. The read cache driver caches data which is read out from the server by the filter driver in the storage device.Type: GrantFiled: May 5, 2008Date of Patent: April 30, 2013Assignee: Co-Conv, Corp.Inventors: Shin Maruyama, Masahiro Kozuka

Publication number: 20110275126Abstract: Provided are a simple method for producing a nucleic acid sample that does not need to use high-risk chaotropic salt in large amounts, does not need to use a limited special carrier, and offers a superior level of safety; and a method for producing a nucleic acid amplification product using the same. With respect to a cell sample containing cells, by releasing nucleic acid complexes from the cells and bringing this treatment liquid into contact with a carrier, the nucleic acid complexes are held in the carrier. Further, in the presence of a dispersion medium, by applying heat treatment to the carrier, DNAs such as genomic DNA and mitochondrial DNA, and RNA are released. Thereby, a nucleic acid sample can be recovered.Type: ApplicationFiled: January 15, 2010Publication date: November 10, 2011Applicant: ARKRAY, Inc.Inventor: Masahiro Kozuka
