  • Patent number: 8605458
    Abstract: A floating electrical connection device includes a base, a support plate, a circuit board, an electric connector, and at least one spring. The base includes a bottom wall and two sidewalls. Each of the sidewalls is formed with a guide slot. The support plate is disposed between the sidewalls, and is spaced apart from the bottom wall. The support plate includes two sliding members disposed respectively on left and right sides thereof, and extending respectively and movably into the guide slots. The circuit board is disposed on the support plate. The electric connector is disposed on the circuit board, and is electrically connected to the circuit board. The spring is disposed for biasing the support plate away from the bottom wall. As such, the electric connector can be electrically connected to an additional electric connector at a selected one of at least two predetermined positions.

  • Publication number: 20120250270
    Abstract: A protective casing adapted for an electronic device includes a lower casing, an upper casing and a back cover. The upper casing cooperates with the lower casing to form a first accommodating space therebetween. The back cover is detachably accommodated in the first accommodating space and used to house the electronic device.

  • Patent number: 8191706
    Abstract: A protective casing is adapted for a first electronic device with a first button and a second electronic device with a second button. The protective casing includes a lower casing and an upper casing. The lower casing includes a partition member disposed therein. The partition member has a first resilient arm extended from a periphery of the partition member. The upper casing cooperates with the lower casing to form a first accommodating space, wherein the first accommodating space is above the partition member. When the first electronic device is accommodated in the first accommodating space, the first button is at a first distance from a bottom of the partition member. When the second electronic device is accommodated in the first accommodating space, the second button is at a second distance from the bottom of the partition member. A length of the first resilient arm covers the first and second distances.

  • Patent number: 8104615
    Abstract: A tool positioning pad has a body, at least one positioning slot and two containing recesses. The body is a plastic foam block and corresponds to and is normally mounted in a tool box. The at least one positioning slot is formed in the body and each position slot has two ends and at least one non-straight section. Each non-straight section may be arced or curved and is integrally formed longitudinally in the positioning slot and has a convex inner sidewall. When a thin tool such as a spanner is placed into a positioning slot, the convex inner sidewall is deformed to press and securely hold the spanner inside the positioning slot.

  • Publication number: 20060063873
    Abstract: A process for preparing nano water paint comprising the steps of: A. Modifying the chemical property on the surface of nano particles by hydroxylation for forming hydroxyl groups at high density on the surface of the nano particles; B. Forming self-assembly monolayers of low surface energy compounds on the nano particles by substituting the self-assembly monolayers for the hydroxyl groups on the nano particles for disintegrating the clusters of nano particles and for forming the self-assembly monolayers homogeneously on the surface of the nano particles; and C. Blending or mixing the nano particles having self-assembly monolayers formed thereon with organic paint to form nano water paint.

  • Patent number: 6898081
    Abstract: A radiator structure has a circuit board, at least one conductive plate, a radiator board and at least two lock attachments, and reduces the entire radiator structure size to permit micro miniaturization designs and increase the space efficiency without affecting cooling efficiency. The radiator board has a deforming section, which undergoes resilience deformation facing the circuit board to absorb a contact pressure generated between the radiator board, the conductive plate and the microprocessor chip. Use of a spring to absorb the contact pressure is thus not required, which decreases the number of parts and manufacturing costs.
