Abstract: A process forms electrical interconnects between memory bits in a magnetoresistive memory device. An initial dielectric layer is formed to overlie a semiconductor substrate. A magnetoresistive storage layer is formed over the initial dielectric layer. An electrically conductive stop layer that is selective to etch processes and is mechanically hard is deposited over the magnetoresistive storage layer. A hardmask layer is formed to overlie the stop layer. The hardmask layer is etched to expose the stop layer. The stop layer and the magnetoresistive storage layer are etched using ion milling until the initial dielectric layer is exposed, defining individual magnetoresistive memory bits. An isolation layer is formed over the hardmask layer and in the etch regions between magnetoresistive bits. The isolation layer is planarized using chemical mechanical polish (CMP) until the stop layer is exposed.

Abstract: A ceramic heat sink having a micro-pores structure includes a heat dissipation layer, and a thermal conductive layer. The heat dissipation layer forms a ceramic micro-cell structure, which is combined with a sub-micrometer powder, thereby forming the heat dissipation layer. The thermal conductive layer is mounted on the heat dissipation layer to contact with a heat source. Thus, the thermal conductive layer absorbs the heat energy from the heat source; the heat dissipation layer has a micro-pores structure with hollow crystals, and the air functions as the media of heat dissipation, so that the heat dissipation capacity of the ceramic heat sink is greatly enhanced.

Abstract: Wrench capable of preventing a screwed member from slipping out and holding the screwed member. One end of the wrench has a head section formed with a polygonal socket. Multiple teeth are formed on the circumference of the socket for engaging with the screwed member. An annular groove is formed in the head section and a resiliently stretchable retainer ring is disposed in the annular groove. An inner edge of the retainer ring protrudes into the socket to form a stopper section. When the socket is fitted onto the screwed member, the retainer ring serves to stop the screwed member from slipping out of the socket. Also, the retainer ring can be resiliently outward stretched from the annular groove to make the screwed member fitted into the retainer ring and held thereby.

Abstract: A wrench comprises a rod, a retainer, a pressing member, and a casing for accommodating the retainer and allowing relative pivotal movement between the casing and the retainer. The pressing member is received in the casing and slidable along a longitudinal direction of the rod. The pressing member is biased to press against two ends of the retainer, thereby exerting an engaging force between each of two ends of the retainer and an associated one of the ends of the pressing member. When a rotational force applied to the casing is smaller than the engaging force, the retainer and the rod are turned to thereby turn the fastener. When a rotational force applied to the casing is greater than the engaging force, the casing and the pressing member slide while the retainer and the rod are not turned.

Abstract: A resilient retainer ring comprises at least two pressing sections and at least one engaging section.

Abstract: A carpet extractor (10) operable in either a restorative cleaning mode or a maintenance cleaning mode includes a constant rate pump (96) which dispenses clean solution through a manually operated valve (98) to one of two lines (100, 102) having nozzles which restrict dispensing to high and low solution flow rates. In the preferred form, clean solution is dispensed at the high flow rate directly upon the carpeted surface and at the low rate upon the agitating brush (88). When restorative cleaning is desired, the valve (98) is manually moved to dispense at the high flow rate and a switch (110) is also manually moved resulting in the chassis (18) being propelled at a slow working speed. When maintenance cleaning is desired, the valve (98) is manually moved to dispense at the low flow rate and the switch (110) is also manually moved resulting in the chassis (18) being propelled at a fast working speed.
