    • A delay locked loop for generating an internal clock signal locked to an external clock signal includes: a phase detector for detecting a phase difference between the external clock signal and the internal clock signal; a delay unit controller for generating a control signal and a selection signal in response to an output signal of the phase detector; a variable delay device (VDD), responsive to the control signal and a selection signal, to produce a delayed version of the external clock signal on a VDD output line, the variable delay device being configured such that, if the external clock signal undergoes a change from a first frequency to a second frequency significantly different than the first frequency, then a resultant load on the VDD output line nonetheless remains substantially the same.
    • 用于产生锁定到外部时钟信号的内部时钟信号的延迟锁定环路包括:用于检测外部时钟信号和内部时钟信号之间的相位差的相位检测器; 延迟单元控制器,用于响应于相位检测器的输出信号产生控制信号和选择信号; 可变延迟装置(VDD),响应于控制信号和选择信号,在VDD输出线上产生外部时钟信号的延迟版本,该可变延迟装置被配置为使得如果外部时钟信号经历 从第一频率改变到与第一频率显着不同的第二频率,则VDD输出线上的合成负载仍然保持基本相同。

    • An apparatus and a method adapted for shielding and removing fine particles for a portable camera module generated during a portable camera module fabricating process. The portable camera module includes an image sensor and an infrared ray filter. The apparatus includes a tape attaching device for attaching a surface protective tape on a surface of the infrared ray filter so as to prevent fine particles from being attached to the surface of the infrared ray filter, and a tape detaching device movably installed above the surface protective tape in order to detach the surface protective tape having fine particles shielded from the surface of the infrared ray filter. The fine particles are attached to the surface protective tape, which remains shielding the surface of the infrared ray filter during the holder attaching, primary heat treatment, secondary heat treatment, and under filling processes are subsequently carried out. The tape detaching device is moved downward to attach to the surface of the protective tape using vacuum, and is moved upwardly to separate the surface protective tape from the surface of the infrared ray filter, while the vacuum is still being applied.
    • 一种用于屏蔽和去除在便携式相机模块制造过程中产生的便携式相机模块的细颗粒的装置和方法。 便携式摄像机模块包括图像传感器和红外线滤光器。 该装置包括用于在红外线过滤器的表面上附着表面保护带以防止细颗粒附着到红外线过滤器的表面上的带附接装置,以及可移动地安装在表面保护层上的带分离装置 带,以便从具有从红外线过滤器的表面屏蔽的细颗粒的表面保护带分离。 微粒子附着在表面保护带上,在保持器附着,一次热处理,二次热处理和填充过程中,随后进行保持屏蔽红外线过滤器的表面。 带剥离装置向下移动以使用真空附着到保护带的表面,并且在仍然施加真空的同时向上移动以将表面保护带与红外线过滤器的表面分离。

    • A dust collecting container for a vacuum cleaner is removably mounted in a suction chamber of a cleaner body to filter a dust from a dust-laden air being drawn into the suction chamber through an air suction hole that is connected with the outside. The dust collecting container has a dust collecting casing having a connecting hole connected with the air suction hole and a discharge portion for discharging the drawn air, and a filter assembly having at least three filters, and removably mounted at the discharge portion. With the plurality of filters that respectively and consecutively filter from the largest to the most minute particles of the dust-laden air drawn in the dust collecting chamber, the dust collecting container is rarely blocked even for a long period of use.
    • 用于真空吸尘器的集尘容器可移除地安装在吸尘器主体的吸入室中,以通过与外部连接的吸气孔从被吸入吸入室的吸尘空气中过滤灰尘。 集尘容器具有集尘壳体,其具有与吸气孔连接的连接孔和用于排出抽吸空气的排出部分,以及具有至少三个过滤器的过滤器组件,并且可移除地安装在排出部分。 利用从灰尘收集室中吸入的尘埃的空气的最大到最微小的颗粒分别连续地过滤的多个过滤器,即使长时间使用也很少堵塞集尘容器。
