    • A sheet feeding device that uses an air damper for absorbing vibrations when a pick up roller contacts the tray and supported stack of paper. The air damper has a circular tube that has an opening formed in the base of the frame. A piston is then connected to the bottom surface of a tray that is supported in the frame. The piston is pivotally connected to the bottom surface of the tray and protrudes into the circular tube. A plunger is attached to the free end of the piston and maintains contact with the inner surface of the circular tube. The air damper reduces the amount of acceleration that the tray undergoes when the tray is free to move towards the pick up roller of the electrophotographic device.
    • 一种送纸装置,其使用空气阻尼器来在拾取辊接触托盘和支撑的纸叠时吸收振动。 空气阻尼器具有圆形管,其具有形成在框架的基部中的开口。 然后将活塞连接到支撑在框架中的托盘的底表面。 活塞枢转地连接到托盘的底表面并突出到圆管中。 活塞连接到活塞的自由端并与圆管的内表面保持接触。 空气阻尼器减小当托盘自由地朝向电子照相装置的拾取辊移动时托盘经历的加速度。

    • Provided is a method and device for low frequency vibration excitation, which may generate a low frequency using a plurality of ultrasonic generators for high frequency. The method generates ultrasonic waves using a plurality of ultrasonic generators attached to a target structure to induce a beat phenomenon, and extract a frequency lower than a frequency of each of the plurality of the ultrasonic generators to measure a property of the target structure, and thereby may be freely applied to a target structure, regardless of a shape of the target structure such as a plate, a curved pipe, and the like, using a relatively small-sized ultrasonic sensor for high frequency, and may excite a specific frequency of an acceleration range, so that the ultrasonic excitation method may be applicable in a relatively poor Signal-to-Noise Ratio (SNR) range.
