    • A working roll shift type rolling mill has a housing including upper and lower working rolls having working roll chocks, and upper and lower reinforcing rolls having reinforcing roll chocks. Hydraulic rams mounted between the upper and lower working roll chocks apply a vertical force to the vertically facing portions of the respective chocks. The working roll chocks are immovably mounted on their respective working rolls so that they can be moved together. Each of the hydraulic rams has one end mounted in one of the upper or lower working roll chocks and the other end engaging the horizontal wall surfaces of the upper and lower working roll chocks that are vertically adjacent to each other. The working roll chocks and reinforcing roll chocks have flat side surfaces. The housing of the rolling mill includes windows each having a flat side wall such that the working roll chocks and the reinforcing roll chocks may be lifted and lowered within the housing.
    • 工作辊式换辊式轧机具有包括具有工作辊轴承座的上下工作辊和具有加强辊轴承座的上加强辊和下加强辊的壳体。 安装在上下工作辊轴承座之间的液压柱塞对相应的轴承座的垂直面对的部分施加垂直的力。 工作辊轴承座不可移动地安装在它们各自的工作辊上,使得它们可以一起移动。 每个液压柱塞的一端安装在上下工作辊轴承座中的一个中,另一端与上下工作辊轴承座的水平壁面相互垂直相邻。 工作辊轴承座和加强辊轴承座具有平坦的侧面。 轧机的壳体包括各自具有平坦侧壁的窗,使得工作辊轴承座和加强辊轴承座可在壳体内升降。

    • A driver circuit is provided for preventing generation of a pass-through current in a CMOS output unit even if a power supply voltage VDD supplied from a low voltage power supply drops below a recommended operating power supply voltage. The driver circuit includes a level shift unit having PMOS transistors and NMOS transistors, and a CMOS output unit having a PMOS transistor and an NMOS transistor. The source, drain and gate of one PMOS transistor are respectively connected to a high voltage power supply, a first contact and a second contact. The source, drain and gate of a second PMOS transistor are respectively connected to a high voltage power supply, the second contact and the first contact. The source of one NMOS transistor is grounded, the drain thereof is connected to the first contact, and the gate thereof receives a low voltage signal. The source of a second NMOS transistor is grounded, the drain thereof is connected to the second contact, and the gate thereof receives a low voltage signal. In this driver circuit, the driving current of the one PMOS transistor is higher than the driving current of the one NMOS transistor.
