Abstract: PROBLEM TO BE SOLVED: To provide a method for judging whether or not to require the exchange of a conducting roller in an electroplating line in which it is possible to prevent the occurrence of an arc spot due to the occurrence of discharge of a current from a floating substance as a starting point when the floating substance in a plating solution is inserted between a steel sheet and the conducting roller.SOLUTION: In an electroplating line, the particle diameters of floating substances existing in a plating solution are measured to search the average particle diameter D (μm) and the standard deviation σ (μm) in the particle diameter distribution of the floating substances, and then, the surface roughness of the conducting roller is investigated to search maximum height Ry (μm) and ten-point average roughness Rz (μm). When the searched maximum height Ry (μm) and ten-point average roughness Rz (μm) satisfy the following formulas (1) and (2), it is judged that exchange of the conducting roller is not required, and when the searched maximum height Ry (μm) and ten-point average roughness Rz (μm) do not satisfy at least one of the following formulas (1) and (2), it is judged that exchange of the conducting roller is required. Ry≥3×(D+3σ) (1), and Rz/Ry>0.6 (2).

Title: System and method of data transfer through full-duplex differential serial link
Inventor: WU QIANG
IPC: H04L5/14
Filed: 2010-08-23
Abstract: <P>PROBLEM TO BE SOLVED: To differentially transmit high-speed data using a forward channel through a serial link, and transmit comparatively low-speed data that are differentially modulated to forward channel signals using a backward channel through a link.  <P>SOLUTION: Differential modulation is used for both of forward and backward channels, so that signals have a substantially constant common mode voltage and generate low EMI. The spectrum content of signals related to high-speed data may not be substantially overlapped to the spectrum content of signals related to low-speed data. Thereby, high-speed and low-speed data are reproduced at minimum interference. The differential signaling transmission itself transfers data through an inexpensive medium, such as twisted wire pair or parallel PCB trace. The data transmission technologies are applied to various communication network topologies, and point-to-point, daisy-chain and one-to-many communications.  <P>COPYRIGHT: (C)2011,JPO&INPIT
