Abstract: An electrical connection structure is provided. The electrical connection structure includes a through hole, a first pad, a second pad and a conductive bridge. The through hole has a first end and a second end. The first pad at least partially surrounds the first end of the through hole and is electrically connected to a first circuit. The second pad is located at the second end of the through hole and is electrically connected to a second circuit. The conductive bridge is connected to the first pad and second pad through the through hole, thereby making the first and second circuits electrically connected to each other.

Abstract: The present invention discloses a drainage system and drainage pipes thereof. It fulfills the present request for a full coverage of the “capillary drainage belt/board” on a drainage pipe. The present disclosure provides a pipe body, with one or more mounting slot extending the entire length of said pipe body for an installation of the capillary drainage belt/boards. With more than one full-length mounting slot, the slots may be spaced from each other in equal intervals. The present disclosure also provides a fixation mechanism at the mounting slot on the pipe body for securing the capillary drainage belt/board and reinforcing the pipe body strength. The present invention may be manufactured in batch or from a factory assembly line, which lowers construction and labor costs, increases efficiency, increases slotting accuracy, shortens construction time and avoids onsite slotting.

Abstract: An optical aligning apparatus includes: a pendulum disk having a laser illuminator mounted in a lower portion of the pendulum disk, a multiple-pole magnet annularly formed on a collar concentrically secured on a shaft of a rotary machine, an electromagnetic coil device secured in the pendulum disk and rotatably disposed around the multiple-pole magnet formed on the collar; whereby upon rotation of the rotary machine to simultaneously rotate the magnet on the collar secured on the shaft relative to the electromagnetic coil device on the pendulum disk which is gravitationally pendent and stationary, the electromagnetic coil will be electromagnetically induced to produce electricity to power the laser illuminator for projecting a laser optical line to an object for alignment or marking in order to be processed by the rotary machine.

Abstract: A strap drain material adapted for use in soil conservation in the hillside regions, in subterranean drainage for orchards and farmlands and in drainage system of the tunnels, road basement and basement of the buildings is formed on one surface of the flexible strap like or panel like body with a plurality of drainage grooves arranged parallel densely spaced-apart along the direction of the width and extending whole length along the direction of the length and including slit like openings capable of producing capillary action and interior channels expanding to form rounded holes. By the difference in water level at the two ends of the channels or the syphonic force so produced the capacity to absorb water is increased and water is collected and drained away. The interior of the part of the drain material where there is without drainage grooves is embedded with a plurality of longitudinally parallel arranged reinforcements of metal filament, synthetic filament or of crisscross network formed thereof.

Abstract: A strap drain material includes a strap having at least a first and a second side and a first and a second end. At least the first side of the material has a plurality of slots arranged in a spaced-apart fashion along a width of the strap and extending along a length of the strap, and a plurality of notches, each of the plurality of notches corresponding to each of the plurality of slots extending from the slots to a surface of the strap. Each notch is sized such that the notch is capable of creating a capillary action and is adapted to draw liquid from outside of the strap and into the slot corresponding to the notch.
