A regulation method for current limiting control, comprising: S. regulating a current limiting threshold in real time based on a current limiting action: S. controlling switch transistors based on the regulated current limiting threshold. By implementing the regulation method and device, it is made possible to regulate a current limiting threshold in real time directly based on a current limiting action, such that a current uprush in a first PWM wave will be significantly suppressed at the time of sudden loading or occurrence of a short circuit. Further, by regulating the current limiting threshold in real time based on the current limiting action and an inductive current, it is not only made possible to satisfy proper load-carrying capability, but also made possible to prevent a current uprush in a first PWM wave from being too high at the time of sudden loading or occurrence of a short circuit.

A container for packaging items such as semiconductor wafers has a restraining portion with a changeable dimension at an open end that facilitates using conventional loading techniques while also more securely containing the items to avoid undesirable movement of the items in the container. In one example embodiment, the restraining portion includes a sidewall portion that has a first, nominal inside dimension at one end. A second end of the sidewall portion has a second, greater inside dimension at an open end. Another member of the container cooperates with the sidewall portion to change the inside dimension at the open end from the second, greater dimension to the first, nominal dimension. The nominal dimension is selected to correspond to an exterior dimension of the items to be contained within the package so that the container maintains the items in a secure alignment that eliminates lateral movement of the items once the container is secured.
