    • A fuel injector including a valve housing having a nozzle for columnarly injecting fuel and a valve seat continuing from the nozzle; a valve body reciprocatably mounted in the valve housing and having a valve portion adapted to abut against and retract from the valve seat and thereby close and open the nozzle, respectively; and an adapter fixed to a front end of the valve housing. The adapter is formed with an atomizer hole communicating with the nozzle and an assist air passage extending through a side wall of the adapter for supplying an assist air into the atomizer hole to atomize the columnar fuel injected from the nozzle. Both the valve portion and the valve seat are formed to have surfaces in a conical shape so that upon retraction of the valve portion, the space generated between the surfaces becomes uniform over substantially the length of the surfaces.
    • 一种燃料喷射器,包括具有用于柱状喷射燃料的喷嘴和从所述喷嘴延续的阀座的阀壳体; 阀体,其可往复运动地安装在所述阀壳体中并且具有阀部分,所述阀部分适于抵靠所述阀座并从所述阀座缩回,从而分别关闭和打开所述喷嘴; 以及固定到阀壳体的前端的适配器。 适配器形成有与喷嘴连通的雾化器孔和延伸穿过适配器的侧壁的辅助空气通道,用于将辅助空气供应到雾化器孔中以使从喷嘴喷射的柱状燃料雾化。 阀部分和阀座都形成为具有圆锥形状的表面,使得在阀部分缩回时,表面之间产生的空间在基本上表面的长度上变得均匀。

    • A practical novel phosphor material composed of an α-type silicon nitride, i.e., an α-type silicon nitride phosphor containing a fluorescence-emittable element throughout an α-type silicon nitride particle from the surface to the inside, is provided. Portions having a high emittable element concentration are preferably present like islands, and the fluorescence-emittable element is preferably a lanthanide metal. A powder composed of a fluorescence-emittable element is added to silicon diimide (Si(NH)2) or an amorphous silicon nitride powder obtained by thermally decomposing silicon diimide (Si(NH)2), the powders are mixed, and the mixture is fired in a non-oxidizing atmosphere, whereby the phosphor material is obtained.
