摘要:
A method of controlling a stage comprising: acquiring a first moving speed of the stage based upon position information from a laser interferometer for measuring a position of the stage; controlling the moving speed of the stage based upon the first speed; determining a second moving speed of the stage based upon the number of rotation of a motor for moving the stage; controlling the moving speed of the stage based upon the second moving speed; and acquiring a ratio of the second moving speed to the first moving speed based upon the first moving speed.

The disclosure is concerned with An electromagnetic shielding plate comprising an electromagnetic shielding member of electrical conductivity and a front panel disposed to an end of the electromagnetic shielding member. The disclosure is also concerned with a circuit board chassis, which comprises a casing, guide rails disposed in the inside of the casing for inserting circuit boards and a plurality of electromagnetic shielding plates each comprising an electromagnetic shielding member and a front panel, the electromagnetic shielding plates being located between the circuit boards, wherein the electromagnetic shielding plates and the casing are electrically connected by means of front panels.
摘要:
A video signal switching system wherein existing network components and the like are used to perform a switching process, thereby reducing the costs and improving the versatility as well. As a solution, a video signal switching system is provided which comprises a plurality of input port components that acquire non-packet digital consecutive signals; a plurality of output port components that output the non-packet digital consecutive signals; a packetizing unit that packetizes the acquired non-packet digital consecutive signals into packets after associating them with the input port identification information of the input port components having acquired them; a switch unit that distributes the packets to the output port components in accordance with the input port identification information associated with those packets; and a restoring unit that restores the packet signals distributed by the switch unit to the non-packet digital consecutive signals.
