A method for making a magnetic data storage target includes warm-rolling a magnetic alloy sheet at a temperature of less than about 1200.degree. F., optimally followed by annealing. The method results in increased pass-through-flux (PTF) and improved performance in magnetron sputtering applications.

A thread structure for an optical lens comprises a plastic lens barrel, and the thread structure is formed on an outer surface of the lens barrel. In each single circle of the thread structure there is a normal thread and a partial withdraw thread. The partial withdraw thread is located on a longitudinal parting line of the thread structure, a top diameter and a pitch circle diameter of the partial withdraw thread are smaller than those of the normal thread, the thread structure is provided with ribs that are located at the root of a first normal thread close to the front end of the lens barrel. The withdraw thread produces an interval between the thread structure and the base, thus preventing the burrs on the parting surface from contacting the inner threads of the base and causing powder.

A route manager queries a new network element to identify egress routes coupled to the network element and to identify external nodes coupled to the egress routes. The route manager queries a database with identifiers for the external nodes to identify associated telephone numbers. For each telephone number associated with an external node, the route manager associates the telephone number with the egress routes coupled to the external node and with the new network element. The route manager receives a call request to one of the telephone numbers, and in response, selects the new network element and one of the egress routes associated with the telephone number.

A board for testing DVD (Digital Versatile Disc) ROM (Read Only Memory) chip-set and associated circuit for generating radio frequency signals with phase difference are provided. The circuit includes signal potential dividers, high pass filters, and a phase shifter. The circuit receives a digital input signal, which has a predetermined frequency, generated by a chip test device. The radio frequency signals with phase difference for testing the analog circuit block of DVD ROM chipset are generated according to the received digital input signal. Therefor, the high temperature operating life test for optical disc drive chips can be achieved.
