Abstract: The present invention relates to an anti-surf head on a dry-type snorkel, including a buoy formed on a lateral, an air chamber formed in a lid to increase buoyancy, thereby keeping an upright floating to prevent the buoy from fast shutting off or prevent seawater from entering the snorkel easily, and a set of guiding groove formed on a bottom of a partition to facilitate draining water out of the snorkel without causing retro-flow.
Abstract: An all-directional damping and earthquake-resisting unit is fixed to a lower part of an object, such as a column of a building, and a foundation for the object, so that functionally different members of the unit normally bear the weight of the object. When there is an earthquake, round balls included in the unit automatically roll and rotate on ball restoring means provided on two ball carriers while a piston assembly automatically moves in a buffer space, so that an instantaneous impact by the earthquake energy and any earthquake-induced displacement are absorbed by the unit. The balls and the piston assembly finally automatically return to their original positions in the unit, enabling the object and the foundation thereof to always locate at the same place without the risk of deviating from their centers.
Abstract: A closed-type drying system a drying chamber with glass windows to allow light entering, an condensation and heating system connected between two distal ends of the drying chamber and controlled by an automatic control system, the condensation and heating system including an air blower for blowing air through the drying chamber, a heater for heating air passing through the drying chamber, two evaporators for condensing moisture from output air of the drying chamber, a heat energy reclamation chamber connected between the air blower and the evaporator, a condenser mounted inside the heat energy reclamation chamber for preheating air passing through the heat energy reclamation chamber, a first compressor mounted in the heat energy reclamation chamber for heat exchange with the flow of air passing through reclamation chamber, and a second compressor adapted to provide low temperature conditions (if needed) in the drying chamber.

Abstract: An alignment mark is made of at least two nonparallel trenches having two reducing-width-to-zero ends. The displacement bias error, produced by a process bias error, of the centerlines of the trenches is zero where the width of the two trenches is zero. Hence, the alignment target on a substrate can be reproduced.
Abstract: A screen-printing method for use in IML hot press, die cutting, and injection molding is disclosed to print first, second, and third (special) colors of a four-color printing with ink mixtures containing different printing inks and a hardening agent with a bonding agent, and then to perform ex-design first, second and third screen printings, and then to process the semi-finished printing work thus obtained through a hot work die treatment, a die-cutting process, and an injection-molding process so as to obtain the desired finished product.
Abstract: A lug engagement structure for an electrical connector. The connector includes a plastic base formed with a receiving slot. The structure can engage with a lateral engagement hole of a circuit board inserted into the electrical connector. The structure includes a board removing component pivoted to the base and rotatable within the slot. A push block extending forward and pressing against the circuit board is arranged on a bottom of the component. A pressing portion and an engagement portion extending forward are arranged on a top of the component. The engagement portion engages with the lateral engagement hole of the circuit board, and the pressing portion can be elastically moved up and down and has a resistant plate. The base has an engagement arm elastically engaging with the component. When the pressing portion is pressed down, the resistant plate is caused to push the arm to separate from and disengage with the component.
Abstract: An image sensor includes a substrate, a metal sheet, a photosensitive chip, a plurality of wires, and a transparent layer. The substrate has a slot. The metal sheet is attached to the lower surface of the substrate and located under the slot to form a cavity together with the slot. The photosensitive chip is arranged within the cavity and mounted to the metal sheet. The wires electrically connect the photosensitive chip to the substrate. The transparent layer is arranged on the substrate to cover the photosensitive chip. Thus, the photosensitive chip may receive optical signals passing through the transparent layer.
Abstract: A signal light and rear-view mirror arrangement is constructed to include a circuit board mounted in the back recess of a vehicle rear-view mirror and adapted to control a set of lamps to flash, and a lens covered on the back side of the vehicle rear-view mirror, the lens having a plurality of raised portions protruded from the inner surface and forming a honeycomb-like condensing area adapted to condense and refract light from the lamps, a transparent area surrounding the honeycomb-like condensing area, and a photomask covered on the outer surface of the lens corresponding to the condensing area.
Abstract: A closed box structure of a horizontal linear motor machine tool, comprising a frame, serving as a machine platform, carrying an X-movable part, a Y-movable part, and a Z-movable part, with said Y-movable part mounted on said X-movable part, said Z-movable part mounted on said Y-movable part, and said Z-movable part having a main axis head; characterized in that said frame, said X-movable part and said Y-movable part are shaped like open squares, said X-movable part, said Y-movable part and said Z-movable part each carry a set of two symmetrically adapted linear motors for being driven, wherein for each of said sets of linear motors magnetic forces are balanced against each other, so that deformations due to magnetic forces are avoided.

Abstract: A gas-economizing powerful engine speed increaser is made integral, and positioned fixedly in an air intake tube connected with the front end of an air intake manifold of an engine. The engine speed increaser consists of an outer circular tube, an inner circular tube of a shorter diameter than that of the outer tube and positioned in the center of the outer tube, and a plurality of twisted leaves positioned spaced apart equidistantly between the outer tube and the inner tube. Air sucked in an air intake tube by the engine started and under operation flows through the engine speed increaser to become swirl wind by the twisted leaves and partly straight wind flowing swiftly through the center hollow of the inner tube and then enter the combustion room of the engine.
Abstract: A combination lock comprises a first shackle, dials, a spring loaded member biased against the innermost dial, a second shackle comprising an inner arm, a moveable block pivotably coupled to the inner arm and including a spring and an opposite T-shaped slot, and a key opening mechanism aligned with the moveable block and comprising a shaft and a cross member. Inserting a key into the mechanism and turning the key will rotate the shaft and the cross member until the cross member is aligned with an opening of the slot such that pressing the second shackle will cause the inner arm to counterclockwise pivot about the member, move the moveable block outwards to compress the spring and dispose the cross member in the opening, and disengage the second shackle from the first shackle.
