    • The process for manufacturing a platinum temperature-measuring resistance element comprises the step of preparing a thermosensitive part having a portion to be sealed coated with a glaze; the step of placing a pre-sealing element on a tray and inserting the same in a chamber; the step of enclosing a purge gas containing an inert gas and oxygen in the chamber; the step of raising the internal temperature of the chamber to a region in which the platinum is in reduced form at a partial pressure of oxygen in the purge gas as determined from platinum oxide formation free energy; the step of replacing the purge gas with an inert gas wherein oxygen is 1 kPa or below; and the step of under the replaced condition, rapidly heating the furnace interior (interior of the chamber) to a fit melting temperature by means of a lamp heating unit to thereby seal the portion to be sealed of the thermosensitive part.
    • 制造铂温度测量电阻元件的方法包括制备具有用釉料涂覆的部分的热敏部分的步骤; 将预密封元件放置在托盘上并将其插入室中的步骤; 将包含惰性气体和氧气的吹扫气体封闭在室中的步骤; 将氧化铂形成自由能确定的在净化气体中的氧分压下将室的内部温度升高到铂还原形式的区域的步骤; 用氧气为1kPa以下的惰性气体代替吹扫气体的步骤; 以及在替换条件下的步骤,通过灯加热单元将炉内部(室内)快速加热至适合的熔化温度,从而密封热敏部件的待密封部分。

    • A focus adjustment method of an LED print head of an image forming apparatus, including steps of: setting one end with respect to a longitudinal direction of the LED print head on a first position where a distance between the photoconductor and the LED print head becomes shorter than a designed focal length, and setting other end with respect to the longitudinal direction of the LED print head on a second position where the distance between the photoconductor and the LED print head becomes longer than the designed focal length; outputting a pattern image having a predetermined resolution; and adjusting the position of the LED print head by moving each of the one end and the other end of the LED print head, based on information of the resolution of the outputted pattern image.
    • 一种图像形成装置的LED打印头的聚焦调整方法,包括以下步骤:将所述LED打印头的纵向方向的一端设置在所述光电导体和所述LED打印头之间的距离变短的第一位置 并且在第二位置处相对于LED打印头的纵向设置另一端,其中光电导体和LED打印头之间的距离变得比设计的焦距长; 输出具有预定分辨率的图案图像; 并且通过基于所输出的图案图像的分辨率的信息,通过移动LED打印头的一端和另一端来调整LED打印头的位置。

    • An optical connector consists of a ferrule unit including an optical fiber, a ferrule rigidly fitted to one end of the optical fiber, and a spring placed around the optical fiber which abuts at one end against the ferrule, a plug housing which receives the ferrule unit, and a spring cap having a rear wall and a fiber letting-out portion formed in the rear wall through which the optical fiber is let out. The spring cap is fittable, with the spring abutting at the other end thereagainst, to the plug housing. The plug housing has a resilient protecting means which, when the spring cap is fitted to the plug housing, overhangs a part of the optical fiber let out through the fiber letting-out portion of the spring cap. The optical fiber is protected at that port let out of the spring cap if bent.
    • 一种光学连接器包括一个套圈单元,包括一个光纤,一个刚性地装在光纤一端的套圈,以及一个围绕光纤放置的弹簧,一端靠在套圈上;一个插头壳体, 以及弹簧盖,其具有形成在后壁中的后壁和光纤出射部分,光纤通过该外壁出射。 弹簧帽是可装配的,弹簧的另一端靠在插头壳体上。 插头壳体具有弹性保护装置,当弹簧盖装配到插头壳体时,突出部分的光纤通过弹簧盖的光纤出口部分伸出。 如果弯曲,光纤在该端口处被保护。
