These compounds generally have the crystalline structure of a skutterudite, wherein the crystalline structure is cubic with 34 atoms in the unit-cell in the space group Im3. The M".sub.12 atoms occupy unit-cell sites 24(g), the M'.sub.4-y atoms form a cubic sublattice occupying unit-cell sites 8(c), and the M.sub.1-x atoms are positioned in two remaining "holes" or interstitial sites in the unit-cell, namely sites 2(a). These thermodynamically metastable skutterudite crystalline-structured compounds possess relatively low thermal conductivity properties with relatively high electrical conductivity properties, making the compounds ideal for use in thermoelectric devices.

    • A method of and apparatus for rapidly modifying the user base registers of an instruction processor. In accordance with the present invention, a load base register user instruction may request an operand from a cache memory, wherein the requested operand may provide a new L field and a new bank descriptor index field. An unconditional compare may be made between the new L,BDI fields and the prior L,BDI fields, regardless of whether the requested operand providing the new L,BDI fields actually resides in a corresponding operand cache. In parallel therewith, the operand cache may determine whether or not the requested operand that provided the new L,BDI fields actually resides in the cache memory. A selector block may then determine if the new L,BDI fields match the previous L,BDI fields, and if the requested operand that provided the new L,BDI fields actually resides in the cache memory. If so, a fast load base register algorithm may be used to load the base register. If not, a slow load base register algorithm may be used.
    • 一种用于快速修改指令处理器的用户基本寄存器的方法和装置。 根据本发明,负载基址寄存器用户指令可以从高速缓存存储器请求操作数,其中所请求的操作数可以提供新的L字段和新的存储体描述符索引字段。 可以在新的L,BDI字段和先前的L,BDI字段之间进行无条件比较,而不管提供新的L,BDI字段的请求操作数是否实际驻留在相应的操作数高速缓存中。 与此同时,操作数高速缓存可以确定提供新的L,BDI字段的所请求的操作数是否实际驻留在高速缓冲存储器中。 选择器块然后可以确定新的L,BDI字段是否与先前的L,BDI字段匹配,并且如果提供新的L,BDI字段的所请求的操作数实际驻留在高速缓冲存储器中。 如果是这样,可以使用快速加载基址寄存器算法来加载基址寄存器。 如果不是,则可以使用缓慢的负载基址寄存器算法。

    • A computer docking system (10, 10') has a computer (11, 11') provided with a guide housing (12, 12') within which a device (13, 13') is slidably inserted. In one embodiment, the device (13) carries a pair of manually-releasable spring-loaded latches (24, 25) pivotally mounted thereon about respective axes which are substantially perpendicular to the direction which the device (13) is slidably inserted into the guide housing (12) for engagement with respective hooks (36) on the computer (11). In another embodiment, the latches (51, 52) are pivotably mounted on the guide housing (12') about respective axes which are substantially parallel to the direction in which the device (13') is slidably inserted into the guide housing (12'). The guide housing (12') includes a fixed bottom portion (44) on which the latches (51, 52) are pivotably mounted, and further includes a spring-loaded movable top portion (45) receiving the device (13') and ultimately nested telescopically within the fixed bottom portion (44). In each embodiment, a substantially zero insertion force ("ZIF") is achieved between at least one flexible electrical connector (41, 57, 58) and a circuit pad (43, 60, 61) as the device (13, 13') is inserted into the guide housing (12, 12').

    • A pair of printed circuit boards (11, 12) angularly converge towards each other about a pivot axis (13). Each of the boards (11, 12) carries a connector housing (16). The connector housings (16) are identical, but are inverted end-to-end with respect to each other, such that a plurality of hermaphroditic guide fingers (19) on one of the connector housings (16) will mesh with a complementary plurality of guide fingers (19) on the other connector housing (16). The meshing engagement of the guide fingers (19) provides a guide means and a stop means between the connector housings (16) and hence between the printed circuit boards (11, 12). Each of the identical connector housings (16) further has a flexible electrical connector (17), and the flexible electrical connectors (17) engage each other when the printed circuit boards (11, 12) are fully converged. Inclined surfaces (21, 22) on the meshing guide fingers (19) provide a self-alignment feature as the printed circuit boards (11, 12) and the connector housings (16) thereon are angularly converged. Preferably, each connector housing (16) has spaced-apart pairs of bifurcated latching fingers (23) such that the connector housing (16) is "snapped" on to its respective printed circuit board (11, 12).
