    • A digitizer tablet has a base integrated with a heat sink. The base includes a flat portion which surrounds the heat sink. The sink is recessed relative to the flat portion and includes a flat upper surface on which a thermal pad is mounted. A planar member overlies the base and has a plurality of heat generating modules mounted on the underside thereof, the modules being pressed into the thermal pad to establish a thermal conduction whereby heat flows from the modules through the thermal pad and into the heat sink. The underside of the heat sink is recessed and has a plurality of cooling pins which provide a relatively large area. The pins are cooled by natural air convection and radiation, and lie within the recess to prevent body contact with portions other than the tips thereof. Bosses mount the planar member on the base and coact with fasteners to press the modules against the thermal pad.
    • 数字转换器平板电脑具有与散热器集成的基座。 基座包括围绕散热器的平坦部分。 水槽相对于平坦部分凹陷并且包括平坦的上表面,其上安装有热垫。 平面构件覆盖在基座上并且具有安装在其底侧上的多个发热模块,模块被压入热垫以建立热传导,由此热量从模块通过热垫流入散热器。 散热器的下侧凹入并具有多个提供较大面积的冷却销。 销通过自然空气对流和辐射而被冷却,并且位于凹槽内,以防止与其尖端之外的部分的体部接触。 凸台将平面构件安装在基座上并与紧固件共同按压模块抵靠散热垫。

    • The present invention provides a compound comprising a quaternary ammonium salt of a sulfonylurea having the formula wherein R1 is a substituted or unsubstituted phenyl, heterocyclic ring, or phenoxy, or —N(CH3)(SO2CH3); R2 is H or CH3; R3 is a substituted or unsubstituted pyrimidine or a substituted or unsubstituted triazine; R4 and R5 are independently unsubstituted or hydroxy substituted linear or branched C1-C4 alkyls, —(CH2CH2O)mCH2CH2OH, or —(CH2CHCH3O)mCH2CHCH3OH where m is 1 to 10; R6 is a substituted or unsubstituted benzyl, ethylbenzyl, naphthylmethyl, or linear or branched C1-C22 alkyl; R7 is a substituted or unsubstituted, linear or branched C8-C22 alkyl or —R13(O)n(C6H5)R14 where n is 0 or 1; R13 is a substituted or unsubstituted C1-C8 alkyl or C1-C8 alkoxyalkyl; and R14 is a substituted or unsubstituted, linear or branched C1-C12 alkyl. Also, a method of preparing a quaternary ammonium salt of a sulfonylurea is provided. The method comprises contacting a quaternary ammonium hydroxide and a sulfonylurea to form the quaternary ammonium salt of the sulfonylurea. The quaternary ammonium salts of a sulfonylurea are useful as herbicides, fungicides, and plant growth regulating agents.
