Abstract: A health care device and a health care method are illustrated, the health care method is used to arrange the health care device at a predetermined location in front of a belly button of a user with a predetermined distance, and to emit the low-frequency wave with a predetermined frequency to the belly button by using a low-frequency wave emitter. The health care device is formed by the low-frequency wave emitter and a cone/pyramid part. The predetermined frequency is 1.27 Hz to 1.81 Hz, and the predetermined distance is 5 cm to 8 cm. The above health care device and method can increase contents of active T cells and B cells in blood and increase an ability of NK cell strains for poisoning cancer cell strains (K562). In short, the above health care device and method have health benefits without a risk of excessive energy causing harm.

Abstract: An apparatus includes a six-axis correction stage, an auto-collimation measurement device, a light splitter, a telecentric image measurement device, and a controller. The six-axis correction stage carries a device under test; the auto-collimation measurement device is arranged above the six-axis correction stage along a measurement optical axis; the light splitter is arranged on the measurement optical axis and is interposed between the six-axis correction stage and the auto-collimation measurement device. A method controls the six-axis correction stage to correct rotation errors in at least two degrees of freedom of the device under test according to a measurement result of the auto-collimation measurement device, and controls the six-axis correction stage to correct translation and yaw errors in at least three degrees of freedom of the device under test according to a measurement result of the telecentric image measurement device by means of the controller.

Abstract: A CPU heat sink fastener includes several fasteners with press button on top and a tenor on bottom. After the fastener passes through the heat sink, it applies an elastic part as pressure mechanism to fix the fastener on the fixing hole of the circuitry board. A stable plate with several holding cylinders; each of the fasteners is placed inside one cylinder; an elastic part is under the press button. Two stretch plates with fixing through hole are located in the proper position in the heat sink. The heat sink is on right top of the CPU; the stable plate is on right top of the heat sink to make the holding cylinder faces directly with the stretch plate. Users can push the press button of the fastener and make the tenor pass through the through hole and fix firmly on the fixing through hole of the circuitry board.

Abstract: A CPU heat sink with fan fitting hole includes a heat sink with a plurality numbers of vertical heat dissipating plates on top, the heat sink is fastened to a CPU socket with a fastener. A fan is mounted on top of the heat sink. The vertical heat dissipating plates of the heat sink has a fitting hole on top center; a plurality numbers of bases are equipped on the bottom of the fan. The fastener spans over the vertical heat dissipating plates and fixes the heat sink firmly first, then the fan is fixed on the bottom of the fitting hole of the heat sink by screws pass through the bases. Such scheme can reduce the height of the whole structure; the heat dissipation effect can be more efficiency.

Abstract: An improved structure of heat dissipating components for memory including two components and two fixing nails. One of the components has a hook portion on the upper end. The upper end and center portion of the outer sides of the two components are arranged with a plurality of holes and a sawtooth shaped radiating surface. Two through holes are installed in proper positions at the lower end of each component. The fixing nails pass through the two through holes at the components, each fixing nail is enclosed by a spring and a flange is installed in the front end of the nail. A recess is installed in the center of the lower end of the nail. According to the aforementioned structure, during assembly, the hook portion of one piece will hook the upper end of another component. Then, two fixing nails are pressed into the through holes of the two components. The flange at the front end of the fixing nail will be buckled in the outer side of the component extruding from the through hole.
