The conductive pillar has a first sidewall and a second sidewall opposite to the first sidewall, wherein a height of the first sidewall is greater than a height of the second sidewall. The solder is disposed on and in direct contact with the conductive pillar, wherein the solder is hanging over the first sidewall and the second sidewall of conductive pillar.

Abstract: The present invention relates to a motor device utilizing magnetic force to drive a rotor. The motor device includes a main body, a rotor and a controlling unit. The main body has two openings and an internal chamber. The rotor is magnetic and swingably disposed in the chamber between the two openings. The controlling unit is disposed on outer side of the main body to apply a magnetic force to the rotor for driving the rotor to at least rotate. The rotor is a column body with a certain length. The rotor has a profile corresponding to a configuration of a peripheral wall of the chamber. The outer face of the rotor is formed with at least one spiral groove to define at least one spiral stripe. The rotor is magnetically driven to drive a fluid to flow from one opening to the other opening.

Abstract: A pump unit for magnetically driving an article, including a main body, an article and a coil. The main body has an internal chamber. The article has a certain length and a configuration corresponding to a shape of the chamber. The article is reciprocally movably positioned in the chamber. The coil is wound around the main body and connected with a circuit. The circuit provides a current for the coil so as to drive the article to reciprocally move. The chamber of the main body communicates with two open ends of the main body. The pump unit further includes a first pair of one-way valve sections and a second pair of one-way valve sections. The first and second pairs of one-way valve sections are respectively disposed at two ends of the main body. When the article is reciprocally moved, a fluid can be only driven by the article to flow from a first position to a second position.

Abstract: A current-controlled/driven compensating/strengthening device including a chamber, a driven piece, a coil and at least one compensator. The driven piece has a certain length and a shape corresponding to the shape of the interior of the chamber. The driven piece is movably disposed in the chamber. The coil is arranged around the chamber and connected with a circuit for providing current for the coil to drive and move the driven piece. The compensator is disposed on outer side of the chamber. When the coil is powered on, the compensator serves to compensate and strengthen the magnetic line acting on the driven piece. Accordingly, the action force applied to the driven piece is strengthened.

Abstract: A unit utilizing current to control reciprocation for pushing fluids, including a chamber, a magnet, a coil connected with a circuit, a first inlet, a first outlet, a second inlet, a second outlet, a first valve and a second valve. The magnet is slidably disposed in the chamber. The coil is disposed around the chamber for driving the magnet to reciprocally move. The first inlet and first outlet are disposed at one end of the chamber. The second inlet and second outlet are disposed at the other end of the chamber. The first valve is disposed between the first inlet, the first outlet and the chamber. The second valve is disposed between the second inlet, the second outlet and the chamber. The magnet can drive the first and second valves to suck a fluid into the first and second inlets and push a fluid out of the first and second outlets.

Abstract: A heat-radiating structure with low height, including a first heat-radiating plate and a second heat-radiating plate spaced above the first heat-radiating plate. The first heat-radiating plate is formed with multiple first perforations arranged at intervals and multiple first dents arranged at intervals and extending downward. The second heat-radiating plate is formed with multiple second perforations arranged at intervals and multiple second dents extending downward and fitted with the first perforations. A heat-generating body such as a CPU is adjacent to outer sides of the bottoms of the first and second dents. The heat-radiating structure has a height much smaller than that of a conventional vertical heat-radiating plate and a heat conducting area much larger than that of the vertical heat-radiating plate.

Abstract: A heat absorbing and radiating device includes a driving unit having communicable first fluid outlets and fourth fluid inlets, a heat-exchange unit communicating at an end with third fluid outlets of the driving unit and at another end with an inlet end of a liquid-gas confluence unit, which communicates at an outlet end with an inlet end of a liquid-gas separation chamber, while the latter communicates at an outlet end with one of two second fluid inlets of the driving unit. The driving unit is provided therein with reciprocatingly movable magnets to alternately push first and second fluids into the heat-exchange unit before them enter the fluid-gas confluence unit, so that hot air is finally released from the liquid-gas separation chamber. Since radiating fins and cooling fan are omitted, the device has reduced volume for use with a heat source in a small space, such as a CPU of a portable computer.

Abstract: A food container with a utensil receiving structure includes a container body, a partitioning member, and at least one engaging member. Each of the engaging members may be provided on the partitioning member or the container body for engaging utensils, such as knives, forks, spoons, chopsticks, etc., thereby forming a food container with utensils attached thereto so as to eliminate the trouble to bring along utensils during picnic or the like.
