Abstract: The present invention provides a gauging jig, for gauging whether projections of first and second rollers, which are disposed in parallel on both sides of a carrying surface of a platform, coincide on the surface. The gauging jig includes a pointer instrument which is provided on a side of the platform and perpendicular to the carrying surface. The pointer instrument has a first end and a second end. The first end is connected to the first roller and intersects with a central axis of the first roller, while the second end extends close to the second roller. With the gauging jig, an operator can promptly and accurately gauge whether the projections of the first and second rollers coincide on the carrying surface. Therefore, gauging time can be saved while times of trial production can be reduced or even omitted, thereby improving the production efficiency and reducing cost.

The method includes the steps of: parsing a plurality of buffered commands concurrently (S501); prejudging relationships between a bank and a row of an address to be accessed by each parsed command and a bank and a row of an address for a currently executed command; and transmitting a PRECHARGE command and an ACTIVE command in advance. With the above technical solution, the PRECHARGE command and ACTIVE command which should have been transmitted serially can be transmitted in advance by being hidden in parallel in a Read or WRITE period to thereby make full use of a bandwidth of a DDR device.

Abstract: A contact assembly for an electrical component includes: a bus member; and a switching assembly structured to move between first and second positions. The switching assembly includes: a stationary contact extending from the bus member, a movable contact engaging the stationary contact when the switching assembly is in the first position and disengaging the stationary contact when the switching assembly moves toward the second position, and a switching device coupled to the bus member. When the switching assembly is in the first position, the switching device and the stationary contact are electrically connected in parallel with the bus member and the movable contact. When the switching assembly moves from the first position toward the second position, the switching device disconnects power after the movable contact disengages the stationary contact in order that electrical disconnection between the bus member and the movable contact occurs within the switching device.
