A CPU core voltage switching circuit installed in a personal digital assistant wherein, when the personal digital assistant is using an application software product, a CPU clock frequency is reduced to a half of the frequency used when the personal digital assistant is in an initial start state or a memory data initialization state. The oligosaccharide moieties of glycoprotein molecules are oriented toward the aqueous environment. A slide member is attached to the trailer deck and provides a forward facing slide member engagement surface. The new take-off element does not have a hook and thus does not exhibit any problem regarding process reliability. Transferring means receive, from the collecting means, the exceeding articles and transfer them to an initial section of the selecting member, so that the articles are collected, recycled and their compliance is verified again. The method comprises inducing a resonance within the composite member with the actuator element, detecting the resonance with the sensor element, and altering the resonance by altering the electromechanical coupling of the passive element.
