20140204138 | STORAGE DEVICE AND CONSUMPTION CONTAINER - A storage device includes an interface unit, a storage unit, a detection unit and a control unit. When the detection unit detects a preset trigger condition and the total surplus of the recording material is greater than the capacity of the recording material, the control unit effects the updating of the total surplus of the recording material stored in the storage unit and the erasing of the surplus of the erasable recording material or the consumption amount of the erasable recording material as a calculation value. When the total surplus of the recording material is less than or equal to the capacity of the recording material, the control unit will not actively update the total surplus of the recording material or the consumption amount of the recording material in the storage unit. Provided is a consumption container, which can better manage the data in the storage device. | 07-24-2014 |

20140358894 | OPTIMIZING QUERY STATEMENTS IN RELATIONAL DATABASES - Optimizing query statements in relational databases including determining filtering performance for each of at least two complex predicates in a predetermined layer of the query statement based on a result of a query performed on predetermined data records by using only the complex predicate. The results are ranked based on the filtering performance and re-ordered so that a complex predicate with a higher filtering performance is ranked before a complex predicate with a lower filtering performance. These techniques produce shortened data query response times and improved execution efficiency. | 12-04-2014 |
20150040133 | MULTIPLE STAGE WORKLOAD MANAGEMENT SYSTEM - Provided are techniques for multiple stage workload management. A staging queue and a run queue are provided. A workload is received. In response to determining that application resources are not available and that the workload has not been previously semi-started, the workload is added to the staging queue. In response to determining that the application resources are not available and that the workload has been semi-started, and, in response to determining that run resources are available, the workload is started. In response to determining that the application resources are not available and that the workload has been semi-started, and, in response to determining that the run resources are not available, adding the workload to the run queue. | 02-05-2015 |

20110094720 | SHELL-AND-TUBE HEAT EXCHANGER WITH HELICAL BAFFLES - The present invention provides a single shell-pass shell-and-tube heat exchanger with helical baffles, where within a single pitch, the helical baffles are separated into inner and outer parts along the radial direction of the shell. In the central portion of the inner space of the shell, an inner non-continuous helical form is employed; in other portion outside the central portion, doughnut shaped helical baffles with continuous curved surfaces are arranged to form an outer continuous helical baffle, and the outer helical baffles are arranged to surround the inner helical baffles. Furthermore, the present invention relates to a multiple shell-pass shell-and-tube heat exchanger with helical baffles, in which complete continuous helical baffles are provided in shell-sides other than the inner shell-pass, while non-continuous helical baffles or other flow guide means are employed in the inner shell-pass. The present invention makes flow patterns of fluids on the shell side more desirable, leading to a reduced flow pressure drop, and mitigate fouling, thus the heat transfer rate is improved and the service life of the heat exchanger is increased. The present invention also provides two methods for manufacture of continuous helical baffles, which ensure the concentricity of the tube bundle holes on each continuous helical baffle so as to facilitate installation of heat exchange tube bundles. | 04-28-2011 |
