摘要:
A linear motion apparatus is comprised of: a toothed rail (40); a linearly driving mechanism section (50) having a plurality of swinging plates (53), crankshafts (54, 55), and a casing (51); and guiding means for guiding the casing (51) relatively movably with respect to the toothed rail (40). The casing (51) includes: a pair of side portions (61, 62) which are guided by the guiding means on both sides, in a tooth width direction, of the rail (40); a pair of end plate portions (63, 64) which are located on opposite sides, as viewed in a longitudinal direction of the rail (40), of the swinging plates (53) and connect opposite end portions of the pair of side plate portions (61, 62); and a coupling member (521) which is located between the plurality of crankshafts (54, 55) as viewed in the longitudinal direction of the rail and couple intermediate portions of the pair of side plate portions (61, 62). The coupling member (521) is preferably passed through the swinging plates (53). The linear motion apparatus is compact and low-cost, and capable of maintaining a stable state of meshing between swinging plates and a toothed rail even if a compact casing is adopted.

A mutual exclusion control is performed with dynamically, allocated lock variables. A lock request circuit issues a lock acquisition request or an unlock request. A lock identifying information holding circuit holds an identifying information related to a currently valid lock. A lock identifying information comparing circuit judges whether or not a lock identifying information from the lock request circuit is included in the lock identifying information holding circuit. A lock identifying information updating circuit updates the lock identifying information holding circuit on the basis of the request from the lock request circuit.

A rotary motion to longitudinal motion converting mechanism comprising a passive rack with a plurality of teeth, a plurality of active racks respectively having a plurality of teeth having the same pitch as that of the teeth of the passive rack and meshing with the passive rack, and a plurailty of rotatable crankshafts respectively having eccentric circular portions different in phase from one another and respectively having the active racks supported on the eccentric circular portions in such a manner that the passive rack is moved in its longitudinal direction through the active racks by rotary motions of the plurality of rotatable crankshafts.
摘要:
A nucleic acid-containing complex, containing a nucleic acid and a biodegradable polymer, especially a positively-charged water-insoluble biodegradable polymer, is disclosed. The complex has excellent properties of sustainedly releasing a desired nucleic acid, especially DNA, to a site in need of a treatment. Since the complex can be taken up to phagocytes such as macrophages and delivered specifically to the target site, the function of the nucleic acid can be exhibited in a target site specific manner, and thus more specific gene therapy can be achieved. The complex has no adverse effects, such as occurrence of recombinants or toxicity which could be caused by using a virus vector such as adenovirus, or liposome. Thus, the complex is particularly preferable for the field of gene therapy. Furthermore, the complex enhances the biological effect of the nucleic acid introduced into the cells, allowing a gene therapy with a lower dose of nucleic acids.
摘要:
The present invention provides a vacuum system including a vacuum pump capable of operating at a rotation rate controlled appropriately when a predetermined process is performed in a vacuum chamber, which contributes to energy conservation. The vacuum system serves as a semiconductor manufacturing system comprising a vacuum pump controller which has a gas flow mode and an auto-tuning mode for determining a rotation rate of a vacuum pump unit to set the rotation rate to a target value lower by a predetermined value than the full operation rate of gas flow rate control means under the condition that pressure within the process chamber is vacuum pressure necessary for the gas flow mode. The vacuum pump controller has means for reducing the rotation rate of the vacuum pump unit from a rated rotation rate in the auto-tuning mode under the condition that pressure within the process chamber is vacuum necessary for the gas flow mode, to determine whether or not the operation rate of an APC valve reaches a target value, and means for storing, as the rotation rate necessary for the gas flow mode, the rotation rate of the vacuum pump unit, which is obtained when it is determined that the operation rate of the APC valve reaches the target value.
