    • The present invention relates to a dental implant abutment and to a method for manufacturing same, and more particularly, to a dental implant abutment which supports a porcelain prosthesis so as to define the outer appearance of an artificial tooth, and which his fixedly coupled to a fixture, and to a method for manufacturing same. The dental implant abutment includes: a first part having a coupling structure corresponding to the inner structure of a fixture such that the first part is coupled to the fixture; a second part extending upward from the first part so as to contact the gums; and a third part extending upward from the second part, the outer circumferential surface of the third part including side and top surfaces, wherein porcelain is attached to the outer circumferential surface of the third part, a concave portion that is inwardly recessed is defined in the top surface, and the third part has a horizontal cross-sectional area that gradually increases as it progresses upward from the concave portion.

    • The present invention relates to an oil pressure system for a wheel loader, and more particularly to a wheel loader which includes an oil pressure system having a confluent circuit and reduces the occurrence of impact during a loading work. To this end, the present invention provides the wheel loader which is composed of an oil pressure circuit characterized by setting different cutoff pressure values with respect to a pair of left and right oil pressure pumps connected through the confluent circuit. Accordingly, the present invention can prevent loss of products loaded in a bucket due to an abrupt halt of a boom during the loading work and can remarkably reduce the impulse of the wheel loader by operating the boom at a remarkably low speed in comparison with the maximum speed when the boom approaches the maximum height in a rising process thereof during the loading work of the wheel loader.
    • 轮式装载机用油压系统技术领域本发明涉及一种轮式装载机用油压系统,特别是涉及一种具有具有汇合回路的油压系统并且减少装载作业时的冲击发生的轮式装载机。 为此,本发明提供一种轮式装载机,该轮式装载机由油压回路构成,其特征在于,对通过汇合回路连接的左右一对油压泵设定不同的截止压力值。 因此,本发明能够防止在装载作业中由于动臂突然停止而装载在铲斗中的产品的损失,并且与最大速度相比,通过以显着低的速度操作动臂而显着减小轮式装载机的冲量 当在轮式装载机的装载作业期间悬臂在其上升过程中接近最大高度时的速度。
