Abstract: A suspension device for a tool handle has a body (10) with a U-shaped recess (13), and an elastic bracket (20) mounted on the body (10) at two ends in front of the U-shaped recess (13). When the tool handle presses the elastic bracket (20) and the tool handle into the U-shaped recess (13), the tool handle is clamped by the deformed elastic bracket (20) within the U-shaped recess (13). Thereby, the tool handle is directly mounted in the suspension device by simple pressing. Additionally, the body (10) can be detachably mounted on a track assembly to adjust the position of the suspension device and the tool handle.

Abstract: A land grid array connector (1) for electrically connecting a CPU package (3) to a printed circuit board includes a housing (2) and a number of contacts received in passageways (284) of the housing. The housing has a bottom wall (28) and sidewalls (22,24,26). The bottom wall and the sidewalls cooperatively define a receiving space (20) for accommodating the package therein. Protrusion member (228) is formed on the sidewalls and extends inwardly into the receiving space. A through hole (280) below the protrusion member is defined in the bottom wall for facilitating molding the protrusion member. The protrusion member is configured with a vertical abutting surface (2280) formed at a lateral end toward the receiving space thereof. The bottom wall forms a mounting surface (2820) for sustaining the CPU chip thereon. A vertical shortest distance is formed between a lowest end of the abutting surface of the protrusion member and the mounting surface of the bottom wall.

Abstract: A method of preparing a test sample for electron microscopy analysis is disclosed. First, a chip segment is attached to a holder of a sample polisher, and a first polishing end of the chip segment is polished by using the sample polisher to generate a first polished cross section. Thereafter, the chip segment is detached from the holder. Further, a carrier segment is attached to the first cross section of the chip segment and the conjoined carrier segment and the chip segment are attached to a pad segment so as to form a stacked structure. Finally, the stacked structure is attached to the holder, and a second polishing end of the chip segment is polished to generate a second polished cross section.

Abstract: The invention relates to a pliable connector comprising a plurality of metal conductor wires arranged as the plurality of parallel coplanar ones being equally spaced apart, a first insulated medium for embedding the conductor wires to form an insulated layer wherein the spacing between any two adjacent conductor wires is not changed and either end of the insulated layer is open, and a second insulating medium coated on both sides of the insulated layer to form a lamination with a predetermined thickness so as to possess a predetermined flexibility and strength and be cut into a plurality of said pliable connectors with predetermined size.

Abstract: Heat sink securing means is adapted to accommodate a heat sink, and has a circuit board (20) sandwiched therein. The securing means includes a retention module (10), a back plate (30), and a plurality of screws (40). The retention module defines a plurality of through holes (12) therein. The back plate defines a plurality of engaging holes (32) corresponding with the through holes of the retention module. The screws extend through the through holes of the retention module and the circuit board, with lower ends of the screws threadedly engaging in the engaging holes of the back plate. The retention module, circuit board and back plate are thereby firmly and securely combined together.

Abstract: A connecting device for gardening tool has a locking sleeve with a screw bolt and a tool head connector firmly secured in the locking sleeve by inserting the cubic part of the connector into the cubic portion of the locking sleeve and screwing the screw bolt on the locking sleeve. The connecting device allows gardening tool heads to be changed easily and conveniently to satisfy different requirements.

Abstract: A Placeable extension tool in this invention is composed of a tool connector (10), a tool head (20), a trigger block (30) and an actuating device (40). The trigger block (30) is a driving element pivotally secured inside the tool connector (10) to control the movement of the tool head (20) but not inseparable with the tool head (20). Thereby, the tool head (20) can be quickly and easily replaced to increase the versatility of the extension tool.
