摘要:
The present invention aims at providing an inorganic fiber molded body that is excellent in scale resistance, thermal shock resistance and mechanical shock resistance, and prevented from suffering from shrinkage when used under high-temperature heating conditions. The inorganic fiber molded body of the present invention is produced by impregnating a needle blanket of inorganic fibers with a liquid material of a precursor of a spinel-based compound represented by the general formula: MgxAlyO4 wherein an atomic ratio (y/x) is not less than 2 (y/x≧2); drying the thus impregnated needle blanket; and firing the dried needle blanket to convert the precursor into an oxide thereof.

摘要:
A magnesium alloy member capable of achieving a mechanical strength and a high-temperature fatigue strength sufficient for a compressor for in automotive air conditioners The magnesium alloy member is formed by subjecting a cast material of a magnesium alloy containing, on the basis of mass %, from 0.3% to 10% calcium (Ca), from 0.2% to 15% aluminum (Al), and from 0.05% to 1.5% manganese (Mn), and containing calcium (Ca) and aluminum (Al) at a calcium/aluminum mass ratio of from 0.6 to 1.7, with the balance being magnesium (Mg) and inevitable impurities to plastic working (extrusion processing) at from 250° C. to 500° C. This makes it possible to obtain a magnesium alloy member having a room-temperature 0.2% proof stress of 300 MPa or more and a 150° C. fatigue strength of 100 MPa or greater.

A motor driven fluid compressor having compression and drive mechanisms within a hermetically sealed housing is disclosed. The compressor includes the compression mechanism, and the drive mechanism. A drive shaft and a motor rotates the drive shaft. A hermetically sealed housing contains the compression mechanism and the drive mechanism. The drive shaft is operatively connected to the compression mechanism, and is rotatably supported by a first inner block and a second inner block which is axially spaced from the first inner block. The first and second inner blocks are integral with first and second portions of the housing, respectively. As a result, the longitudinal axis of holes formed within the first and second inner blocks and the longitudinal axis of the compressor housing are easily and precisely aligned without increasing in the manufacturing cost.

The present invention discloses an orbiting member fluid displacement apparatus including a rotation preventing and thrust bearing device. The rotation preventing and thrust bearing device includes a fixed portion, an orbital portion, and bearing elements. The fixed portion includes a first annular race and a first ring, which are formed separately. The first annular race is placed in a loose fit within a first annular step in an inner surface of the housing and the first ring is attached to the housing. The orbital portion includes a second annular race and a second ring, which also are formed separately. The second annular race is placed in a loose fit within a second annular step in an end plate of the orbiting member and the second ring is attached to the end plate of the orbiting member. A plurality of pockets are formed in the rings and face one another in substantially aligned pairs. A bearing element is received in each aligned pair of pockets to prevent the rotation of the orbiting member by the bearing elements interacting with the first and second rings and to bear the axial thrust load from the orbiting member. One or more lubricant conductive grooves are formed at first contacting surfaces between the first annular race and the housing or second contacting surfaces between the second annular race and the orbiting member, or both.
摘要:
The refrigerated or heated air flow within the storage chamber of a vending machine is varied by an air flow control device. A baffle plate or cover plate, or combination thereof, is used to control the direction of air flow. The position of these plates in turn is controlled by spring elements. One of the spring elements is formed of shaped memory alloy so that its recoil strength changes in accordance with its surrounding temperature. Thus, the difference in recoil strength between these spring elements changes with temperature. That difference is used to position the baffle and/or cover plates to control air circulation.

The present invention provides an apparatus and method for natural language processing capable of providing an appropriate result of natural language processing. More specifically, the present invention provides a natural language processing apparatus for achieving a syntax analysis and/or a syntax generation by using natural language patterns with, at least, pattern name and pattern component. The natural language processing apparatus comprises dictionary reference means for picking up one or more natural language patterns applicable for the syntax analysis and/or the syntax generation among the natural language patterns prepared in a pattern dictionary in advance, pattern inspection means for inspecting whether the applicable natural language patterns meet a tree structure or not, and pattern application means for applying the natural language patterns to the tree structure if the natural language patterns meet the tree structure.

A scroll-type fluid displacement apparatus includes a compressor housing, which contains a compression mechanism and a driving mechanism operatively connected to one another. The compression mechanism includes a fixed scroll and an orbiting scroll interfitting at angular and radial offsets, and a rotation preventing mechanism which prevents rotation of the orbiting scroll during its orbital motion. The driving mechanism includes a drive shaft axially disposed within the housing and rotatably supported by an inner block, which is fixedly disposed within the housing. An axial movement regulating mechanism for regulating an axial movement of the driving mechanism is disposed between the inner block and an internal component of the compressor axially spaced from the inner block. The regulating mechanism includes an annular flange extending from an exterior surface of the drive shaft and a shim which is detachably disposed either between the annular flange and the inner block or between the annular flange and the internal component.
