    • An internal combustion engine includes a split crankcase with spaced-apart journal walls. Each journal wall has a bearing hole formed therein. The engine also includes rotary bearings for supporting rotary movement of a crankshaft. A backlash-absorbing mechanism is situated proximate a first one of the rotary bearings, for cushioning radial movement of an outer bearing race. Axial movement-restraining structure is also provided adjacent the outer race, for limiting axial movement thereof. The axial movement-restraining structure may include an engaging groove provided in an inner circumferential surface of the outer race, and a restraining clamp member operatively attached to a surface of the crankcase. The restraining clamp member may include a hook portion which engages with the engaging groove of the outer race. The axial movement-restraining structure allows at least one of the crankshaft support bearings to be a roller bearing or a needle bearing, instead of a ball bearing.
    • 内燃机包括具有间隔开的轴颈壁的分体式曲轴箱。 每个轴颈壁上都有一个轴承孔。 发动机还包括用于支撑曲轴的旋转运动的旋转轴承。 靠近第一个旋转轴承的间隙吸收机构用于缓冲外部轴承座圈的径向运动。 轴向运动限制结构也邻近外圈设置,以限制其轴向移动。 轴向运动限制结构可以包括设置在外圈的内周面中的接合槽和可操作地附接到曲轴箱的表面的限制夹紧构件。 限制夹紧构件可以包括与外圈的接合槽接合的钩部。 轴向运动限制结构允许至少一个曲轴支撑轴承是滚子轴承或滚针轴承,而不是球轴承。

    • In a manufacturing method of a semiconductor device, a metallic gate electrode film, a protective film and an offset nitride film are formed on a semiconductor substrate to compose a stacked structure. An insulating film which covers the stacked structure is etched to expose the offset nitride film, and the exposed offset nitride film is etched to expose the protective film. The exposed protective film may be etched to expose the metallic gate electrode film under predetermined etching conditions. An etching rate of the protective film is greater than that of the metallic gate electrode film. The etching of the insulating film and the etching of the exposed offset nitride film may form a contact hole. A conductive plug is formed in the contact hole.
    • 在半导体装置的制造方法中,在半导体基板上形成金属栅电极膜,保护膜和偏移氮化物膜,构成层叠结构。 蚀刻覆盖堆叠结构的绝缘膜,以露出偏移氮化物膜,并且暴露的偏移氮化物膜被蚀刻以露出保护膜。 可以蚀刻暴露的保护膜,以在预定的蚀刻条件下暴露金属栅电极膜。 保护膜的蚀刻速率大于金属栅电极膜的蚀刻速率。 绝缘膜的蚀刻和暴露的偏移氮化物膜的蚀刻可以形成接触孔。 导电插塞形成在接触孔中。
