    • The motor includes a cylindrical rotor core, a plurality of magnets axially penetrated in the rotor core, a pair of separation-preventing plates installed at both ends of the rotor core, and at least one fixing member to fix the separation-preventing plates to the rotor core. The fixing member includes a rod portion extending in an axial direction of the rotor core to be disposed on an outer circumferential surface of the rotor core, and supporting portions bent from both ends of the rod portion and used to support the separation-preventing plates. The separation-preventing plates can be fixed to the rotor core by the fixing member disposed on the outer circumferential surface of the rotor core. The fixing member has no risk of hindering the flow of magnetic flux generated from the magnets, resulting in an improvement in the performance of the motor.
    • 电动机包括圆柱形转子铁芯,轴向贯穿转子铁心的多个磁体,安装在转子铁芯两端的一对防分离板,以及至少一个固定部件,用于将防分离板固定到 转子芯。 固定构件包括沿转子芯的轴向方向延伸设置在转子芯的外圆周表面上的杆部分,以及从杆部两端弯曲并用于支撑防分离板的支撑部分。 分离防止板可以通过设置在转子芯的外周面上的固定构件固定到转子芯上。 固定构件没有阻碍磁体产生的磁通的流动的风险,导致电动机性能的提高。

    • A substrate processing apparatus is provided. The substrate processing apparatus includes a substrate supporting member including a spin head on which a substrate is placed, a nozzle discharging processing liquid to the substrate placed on the spin head, and a processing liquid supplying source supplying the processing liquid to the nozzle. The nozzle includes a nozzle main body that has a plurality of discrete discharging openings and an integration discharging opening. The discrete discharging openings have a slit-shaped cross section having a first length and are arrayed in series in a predetermined direction. The integration discharging opening is formed by connecting the discrete discharging openings to each other in a single slot shape having a length greater than the first length, and finally discharges the processing liquid.
    • 提供了一种基板处理装置。 基板处理装置包括:衬底支撑构件,其包括其上放置有衬底的旋转头,向放置在旋转头上的衬底的喷嘴排出处理液;以及将处理液供给到喷嘴。 喷嘴包括具有多个离散排出口和一体排放口的喷嘴主体。 离散排出口具有第一长度的狭缝状横截面并且沿预定方向串联排列。 集成排放口通过以大于第一长度的长度的单个狭槽形状彼此连接而形成,最后将处理液排出。

    • According to an embodiment of the present invention, there is provided a hand lift device including: a frame portion including a vertical frame, a first sprocket installed on an upper end of the vertical frame, and a second sprocket installed on a lower end of the vertical frame; a chain installed to engage with the first sprocket and the second sprocket; a cargo loading unit which is connected with the chain and disposed to be liftable along the vertical frame to load cargo; a power transmission portion which provides a driving force to the chain so that the cargo loading unit is lifted up and down; a sensor portion which is installed in an area where the frame portion is formed to be positioned at an upper side in a range where the cargo loading unit is lifted up and down and includes a proximity sensor to sense the cargo loaded on the cargo loading unit; and a controller which controls lifting up and down of the cargo loading unit by adjusting the driving of the power transmission portion according to a sensing signal from the sensor portion.According to the embodiment of the present invention, since the operator can automatically load the cargo by controlling through the cargo loading unit without manually loading the cargo, the hand lift device can operate faster than manual operation, load more cargo over the same time, and operate with a small number of persons, thereby reducing the cost.
