摘要

NOVELTY - A shift register is provided to sufficiently charge a first node and sufficiently discharge a second node by differentiating a charging time of the first node from a discharging time of the second node.

DETAILED DESCRIPTION - A shift register includes a node controller and a plurality of stages (400a to 400f) having an output unit respectively. The node controller controls a first node and a second node to be charged and discharged. The output unit selectively output a scan pulse and a first voltage source according to a charging/discharging state of the first and second nodes. A time for charging the first node and a time for discharging the second node are difference from each other at each stage.

[0001]技术领域

[0002]本发明涉及保持架技术领域，具体为氮碳共渗的保持架。

[0003]背景技术

[0004]保持架(即轴承保持架，又称轴承保持器)，指部分地包裹全部或部分滚动体，并随之运动的轴承零件，用以隔离滚动体，通常还引导滚动体并将其保持在轴承内。根据专利申请公布号：CN111734743A提出的轴承保持架，该专利公开一种轴承保持架(1)，用于滚动元件轴承，所述轴承保持架(1)包括通过桥(4)连接到彼此的两个侧环(2、3)，其中，在所述桥(4)之间形成被构造用于接纳至少一个滚动元件的腔格(5)，其中，至少一个卡扣表面(6)形成在所述桥(4)上，并且其中，所述腔格(5)和所述卡扣表面(6)是被冲压的。但是现有技术中的轴承保持架的强度较低，容易损坏，并且在使用的过程中耐磨性较差，容易被磨损。因此，需要对现有技术进行改进。
