    • A method of fabricating semiconductor memory devices which has sufficient cell isolation to achieve miniaturization at the 0.3 to 0.4 .mu.m level. In the semiconductor memory devices of the present application miniaturization is achieved by removing overlap allowances between each gate and each LOCOS and those between each diffusion layer and each LOCOS used to separate the above-described semiconductor memory elements. In one embodiment, the method according to the present application includes forming LOCOSs in forms of stripes in parallel with a direction in which a select gate is formed in forming the LOCOSs for separating respective semiconductor memory elements, forming laminated gate portions each including a floating gate and a control gate perpendicularly to the LOCOSs, forming strip-shaped resist layers in parallel with the select gate so as to cover portions to be selection transistors and a part of the upper regions in the selection transistor side of the above laminated gate portions, etching the LOCOSs by using the resist layers and the laminated gate portions as masks, forming impurity diffusion layers to be source lines and drain lines by using the above resist layers and the above laminated gate portions as masks, and then forming select gates, and therefore it does not need the mask matching allowances between the laminated gates and the LOCOSs nor the mask matching allowances between the source diffusion layers and the LOCOSs which have conventionally prevented the miniaturization due to its self-alignment feature. In addition, patterning is performed by combinations of strip and therefore the corners of the LOCOSs are not rounded off so as to decrease the mask matching allowances between the floating gates and the LOCOSs.
    • 一种制造半导体存储器件的方法,其具有足够的电池隔离以在0.3至0.4μm的电平下实现小型化。 在本申请的半导体存储器件中,通过去除每个栅极和每个LOCOS之间的重叠余量以及每个扩散层和用于分离上述半导体存储元件的每个LOCOS之间的重叠余量来实现微型化。 在一个实施例中,根据本申请的方法包括在形成用于分离各个半导体存储元件的LOCOS中形成与形成选择栅极的方向平行的条形的LOCOS,形成各自包括浮置栅极的层叠栅极部分 和垂直于LOCOS的控制栅极,与选择栅极平行地形成条形抗蚀剂层,以覆盖上述层叠栅极部分的选择晶体管和选择晶体管侧的部分上部区域,蚀刻 通过使用抗蚀剂层和层叠栅极部分作为掩模,通过使用上述抗蚀剂层和上述层叠栅极部分作为掩模,形成杂质扩散层作为源极线和漏极线,然后形成选择栅极,因此它们 不需要层压门和LOCOS之间的掩模匹配容限,也不需要掩模匹配余量 源扩散层和LOCOS由于其自对准特征而常规地防止了小型化。 另外,通过条的组合来执行图案化,因此LOCOS的角不会被舍入,以便减小浮动栅极和LOCOS之间的掩模匹配容限。

    • A traveling driving device for a bicycle, which device is capable of increasing rotational torque of a chain wheel using pedaling cranks without elongating a crank arm. This device is borne by a bearing disposed on a frame of the bicycle and has an eccentric plate put on a rotating shaft having cranks with pedal. This eccentric plate is secured to a frame member of the bicycle through a stay portion. The chain wheel is put rotatably on the outer periphery of the eccentric plate through a ball bearing and a working plate secured to the rotating shaft is linked to the chain wheel by linking members. When the rotating shaft is rotated by pedaling action of the cranks, rotation is transmitted to the chain wheel through the working plate and the linking members. Since the chain wheel is rotated in an eccentric state with respect to the rotating shaft, it can be rotated with a rotation radius smaller than a chain wheel having no eccentric mechanism and as a result, rotational torque of the chain wheel is increased, depending on eccentricity length.
    • 一种用于自行车的行驶驱动装置,该装置能够在不使曲柄臂伸长的情况下使用脚踏曲柄增加链轮的旋转扭矩。 该装置由设置在自行车的框架上的轴承承载,并且具有放置在具有带踏板的曲柄的旋转轴上的偏心板。 该偏心板通过支撑部固定在自行车的框架部件上。 链轮通过滚珠轴承可旋转地安装在偏心板的外周上,并且固定到旋转轴的工作板通过连接构件连接到链轮。 当旋转轴通过曲柄的踏板动作旋转时,旋转通过工作板和连接构件传递到链轮。 由于链轮相对于旋转轴以偏心状态旋转,所以能够以比没有偏心机构的链轮小的旋转半径进行旋转,结果,链轮的旋转力矩随着 偏心长度
