    摘要： Disclosed are exemplary techniques for compressing ATM cells by substituting reduced headers for the original headers. A header table may be maintained at the transmitting end whereby headers are stored in table entries based on a table index generated from a hash function applied to the headers. A copy of the header table may be maintained at the receiving end and may be updated by populating idle cells with header table contents. Upon receipt of a reduced ATM cell at the receiving end, the reduced header may be replaced with a full header obtained from the copy of the header table maintained at the receiving end. The present invention further provides techniques for registration and management of hash collisions.

    摘要： A demolding mechanism of mold includes a male mold, a swingable block and an elastic element. The male mold defines a receiving groove therein. The swingable block mounted in the receiving groove of the male mold has a pressing arm and a shaping arm connected with the pressing arm. The shaping arm defines a shaping portion for shaping a part of a product to be molded in the mold. The elastic element is resiliently disposed between the bottom of the pressing arm of the swingable block and the male mold for causing the swingable block to swing, which makes the product be disengaged from the shaping portion of the swingable block.

    摘要： A basic design is disclosed for bottom shield (S1) and top shield (S2) of the reader shields in a magnetic read-write head. The critical part of new design includes an antiferromagnetic film which pins an antiferromagnetically coupled trilayer (AFCT). The simplest embodiment for top shield, for example, would be a film sequence of FM/Ru/FM/AFM. This replaces the normal top shield design which typically comprises a ferromagnetic seed layer and a thicker plated ferromagnetic film. Processes for manufacturing these shields are also described.
