    • According to the present invention, white cement clinker particles are not burned in a rotary kiln and the burned clinker particles are not immersed in the water to be cooled. White cement clinker raw materials are burned in a fluidized bed burning furnace with a fluid bed or a spouted bed and the clinker particles thus burned are reduced with a reducing gas. The clinker particles thus reduced are first cooled with the water which is sprayed over the clinker particles and then further cooled with the air. The white cement clinker raw material particles fed into the fluidized bed burning furnace are burned into clinker particles while forming a fluidized bed and then the clinker particles thus burned drop through a jet injection pipe into a reduction chamber disposed below the burning furnace and are reduced. The clinker particles thus reduced are rapidly cooled to 600.degree.-700.degree. C. with the sprayed water while being isolated from the surrounding atmosphere in a primary cooling chamber and the clinker particles thus cooled are further cooled in a secondary cooling chamber with the air to 100.degree.-150.degree. C.
    • 根据本发明,白水泥熟料颗粒不在回转窑中燃烧,并且烧结的熟料颗粒不会浸入要冷却的水中。 白水泥熟料原料在具有流化床或喷射床的流化床燃烧炉中燃烧,并且由此燃烧的熟料颗粒用还原气体还原。 这样减少的熟料颗粒首先用喷洒在熟料颗粒上的水冷却,然后用空气进一步冷却。 进料到流化床燃烧炉中的白水泥熟料原料颗粒在形成流化床的同时被烧成熟料颗粒,然后通过喷射喷管将熟料颗粒滴落到设置在燃烧炉下方的还原室中并被还原。 将这样还原的熟料颗粒用喷射水快速冷却至600〜-700℃,同时在初级冷却室中与周围环境隔离,并将这样冷却的熟料颗粒在二次冷却室中进一步冷却,空气与 100°-150℃

    • There is provided a focusing system having an autofocusing device. In the focusing system, the range for manual focusing is set beyond the range for autofocusing within which automatic focus adjustment with the autofocusing device operates. The focusing system includes means for operating the autofocusing device to operate automatic focusing of an optical system to be focus adjusted irrespective of the adjusted position of the optical system within the range of manual focusing. Thus, when autofocusing start means is operated, it is possible to automatically adjust the focus of said optical system within the range of autofocusing by the autofocusing device no matter what position the optical system has been taken within the manual focusing range.
    • 提供了一种具有自动对焦装置的聚焦系统。 在对焦系统中,手动对焦的范围超出了自动对焦范围,自动对焦调整在自动对焦设备运行的范围内。 聚焦系统包括用于操作自动对焦装置以操作光学系统的自动对焦以进行聚焦调节的装置,而不管在手动对焦的范围内光学系统的调整位置如何。 因此,当自动对焦启动装置被操作时,无论在手动聚焦范围内采取什么位置,都可以通过自动对焦装置在自动对焦范围内自动调整所述光学系统的焦点。

    • The present invention relates to a system in accordance with which switching signal produced in the one piece of equipment is transmitted to another piece of equipment through a digital/analog converter. The transmitted analog signal is further converted into a digital signal by means of an analog/digital converter in the above equipment so as to carry out the switching control of the circuits and so on in the equipment by means of the signal converted into digital form. This is done so that the transmission of the switching signal between a plural number of pieces of equipment comparatively close to each other or under the condition where mixture of noise hardly cannot readily take place might be realized by means of a very small number of wires.
    • 本发明涉及根据该系统,其中在一件设备中产生的开关信号通过数字/模拟转换器传输到另一设备。 所传输的模拟信号通过上述设备中的模拟/数字转换器进一步转换为数字信号,以便通过转换为数字形式的信号在设备中执行电路等的切换控制。 这样做可以通过非常少量的电线来实现在彼此相对接近的多个设备之间的传输或者几乎不能容易地发生噪声混合的条件下的切换信号的传输。
