    摘要: Disclosed herein are a balancer which is provided with a curved portion at a balancing space so that movement of balls is accelerated at the moment a rotational speed of a rotor exceeds a resonant speed, thereby stabilizing the rotation of the rotor without vibration regardless of when the rotational speed of the rotor is less or more than the resonant speed, and a centrifuge using the above balancer. The balancer includes a body which is formed with a balancing space thereinside. The balancing space has a circular circumference, and is defined by a bottom portion, a slanted portion extending upward from the bottom portion, a curved portion formed at an end of the slanted portion, and an upper large-diameter portion extending from the curved portion. The balancer further includes a plurality of balls which are contained in the balancing space.

    摘要: A method and system are provided for programming a plurality of memory devices arranged in parallel. In one embodiment of the present invention, the plurality of memory devices comprises first and second memory devices, and the method comprises providing successively the first address to the first memory device and the second address to the second memory device. The first address refers to a first group of storage locations in the first memory device and the second address refers to a second group of storage locations in the second memory device. The method then proceeds to load in parallel a string of data to the first and second memory devices so that the string of data is written simultaneously to the first group of storage locations in the first memory device and to the second group of storage locations in the second memory device.
