20100169597 | MEMORY SYSTEM - A memory system comprising a volatile memory unit, a nonvolatile memory unit, and a controller that performs data transfer between a host system and the nonvolatile memory unit via the volatile memory unit stores management information including a storage position of the data stored in the nonvolatile memory unit during a startup operation into the volatile memory unit, and performs, while updating stored management information, data management in the volatile and nonvolatile memory units based on the stored management information. The nonvolatile memory unit includes a snapshot storing area storing a snapshot which is the management information stored in the volatile memory unit at a certain point, a main log storing area storing a main log which is an update information of the management information stored in the volatile memory unit, and a backup log storing area storing a backup log having contents same as contents of the main log. The controller stores the management information of the volatile memory unit in the snapshot storing area as a snapshot when a predetermined condition is satisfied, and sequentially stores the main log in the main log storing area when the management information is changed and the backup log in the backup log storing area. | 07-01-2010 |
20110173380 | MEMORY SYSTEM AND METHOD OF CONTROLLING MEMORY SYSTEM - A first log indicating that a system is running is recorded in a second storage unit before a first difference log is recorded in the second storage unit after system startup, and a second log indicating that the system halts is recorded in the second storage unit following the difference log, at the time of normal system halt, and it is judged whether normal system halt has been performed or an incorrect power-off sequence has been performed last time, based on a recorded state of the first and second logs in the second storage unit, at the time of system startup, thereby detecting an incorrect power-off easily and reliably. | 07-14-2011 |
20110302361 | MEMORY SYSTEM AND METHOD OF CONTROLLING MEMORY SYSTEM - A plurality of free-block management lists for respectively managing a logical block with a same bank number, a same chip number, and a same plane number as a free block, and a free block selecting unit that selects a required number of free-block management lists from the free-block management lists to obtain a free block from the selected free-block management lists are provided, thereby improving writing efficiency. | 12-08-2011 |
20140140890 | AUTOMATIC ANALYSIS DEVICE - The automatic analysis device measures time sequential data on a scattered light amount as reaction process data, and quantitatively determines the concentration of an analyte from a change in light amount. The automatic analysis device has a function of selecting reaction process data to be used for quantitative determination from the reaction process data obtained by measurement using a plurality of light receivers at different angles. As a result of using this function, data is selected from the reaction process data obtained by measurement using the plurality of light receivers at different angles in accordance with the concentration of the analyte and whether the priority is given to high sensitivity in the case where sensitivity is prioritized or a dynamic range, and the result of the quantitative determination is displayed. | 05-22-2014 |
20140220705 | AUTOMATED ANALYZER AND ANALYZING METHOD - An analyzer provides conditions suitable for a reagent for performing latex immunoassay with a high sensitivity using a method of measuring scattered light. Irradiation light having a wavelength in the range of 0.65 to 0.75 μm is used, and scattered light generated from a reaction solution is received at a light-receiving angle of 15° to 35° with respect to the irradiation direction during the rotational movement of the reaction container. The reagent contains latex particles the average peak particle diameter of which ranges from 0.3 μm to 0.43 μm and to which antibodies are sensitized. The reaction solution contains latex particles at a concentration at which the absorbance to irradiation light having a wavelength of 0.7 μm is 0.25 abs to 1.10 abs, and a change in the amount of scattered light caused by the aggregation of the latex particles through antigens in a sample is measured and quantified. | 08-07-2014 |
20140241945 | AUTOMATIC ANALYSIS DEVICE - An automatic analysis device has a light scattering photometer incorporated therein, and improved accuracy resulting from reducing the influences from external light. The automatic analysis device includes a scattered light measurement unit disposed inside the main-body casing, and openable/closable protective covers to cover the top face of the main-body casing. A first protective cover at the center includes a light-shielding part to block external light. The protective covers include see-through parts enabling viewing of the inside. The light-shielding part is configured to cover an area of the reaction disk at least corresponding to the area above the scattered light measurement unit, thus reducing external light leaking into the scattered light measurement unit, and thus removing influences from external light on the scattered light measurement. The protective cover may have a divided structure. | 08-28-2014 |
