An adjustable lens module applied to an image projector is provided. The lens is positioned in a lens barrel situated within a lens housing mounted on a frame. The adjustable lens module includes a base plate, and a first, a second and a third positioning means. The base plate connected to the lens barrel is attached to the lens housing and mounted on the frame. The first, second and third positioning means are respectively positioned at the first, second and third corners of the base plate. The first and second corners are arranged diagonally on the base plate. At least the first and second positioning means are adjustably secured at the first and second corners respectively. By adjusting the relative position between the base plate and the first, second and third position means, a central axis of the lens is substantially parallel to or overlapped with an optical axis.

A hand tool with an adjustable rotational speed and torsion force includes a shaft rotatably received in a body of the hand tool and driven by a motor that is mounted in the body. A first planet gear set is longitudinally connected to one end of the shaft opposite to the motor and a second planet gear set is longitudinally connected to the first planet gear set. The shaft is longitudinally movable in the body. The hand tool only has the first planet gear set acted thereon when the shaft is pushed toward the second planet gear set. The first planet gear set and the second planet gear set are acted on the hand tool at the same time when the shaft is pulled.

A lighter having a two-stage locking type safety switch includes a press member pivotally mounted on the liquid gas container, a first-stage safety switch structure, and a second-stage safety switch structure. The first-stage safety switch structure includes a clutch structure mounted in the press cover, for controlling the press cover and the liquid gas container to be disposed at a first-stage locking or free state. The second-stage safety switch structure includes a locking recess formed in the guide slot of the top cover, so that the locking recess and the guide slot of the top cover may form a substantially L-shaped structure. Thus, the slide knob has to slide in the locking recess to move into the guide slot. Then, the slide knob may move in the guide slot to release the safety switch, thereby igniting the lighter.

A lighter includes an igniting button disposed in a gas container, a block slidably received in the container, a cap engaged on top of the container and pivotally secured to the block with a pivot shaft, and a an actuator secured to the block and moved in concert with the block relative to the container to depress the button for igniting purposes. A latch is slidably received in the an actuator and biased to engage with the cap and to prevent the cap from being rotated relative to the block about the pivot shaft and to prevent the an actuator from being depressed by the children inadvertently.

A nebulization structure with a nozzle plate includes a nozzle plate and a driving element. The nozzle plate is composed of a polymer and a support plate, and the support plate includes a plurality of connecting portions and a through hole, and the polymer covers the support plate and has a plurality of penetrating holes corresponding to the through hole. The driving element is coupled to the nozzle plate through the connecting portions for producing a high-frequency vibration wave through a piezoelectric effect after power is supplied and driving the nozzle plate to vibrate and break up the molecular structure of a solution into a mist, so as to achieve the nebulization effect. The nebulization structure can be installed in a nebulization apparatus to achieve a high-efficiency nebulization effect by the nozzle plate and the driving element, so as to facilitate the manufacturing process and save costs.

An enzyme-linked immunosorbent assay (ELISA) is based on the non-structural protein 7 (nsp7) of porcine reproductive and respiratory syndrome virus (PRRSV) and provides for the simultaneous detection and differentiation of serum antibodies directed against Type 1 (European) and Type 2 (North American) PRRSV. The invention provides a serological assay for the detection and/or differentiation of serum antibodies directed against Type 1 and/or Type 2 PRRSV utilizing PRRSV nsp7 as an antigen, and provides a diagnostic method for the detection of PRRSV infection, epidemiological surveys, and outbreak investigations. The invention may be used either alone or as a follow-up assay to determine the true status of unexpected positive results that may occur using other assays, such as the IDEXX HERDCHEK PRRS ELISA.

A lamp structure comprises an aluminum extrusion pipe, a light transmission cover, and a light emitting member. The aluminum extrusion pipe is axially provided with at least one first sidewall, one second sidewall and one opening, the first sidewall is formed with at least an engaging groove in communication with a through hole in the first sidewall, the second sidewall is provided with at a light reflection surface. The light transmission cover is mounted on the aluminum extrusion pipe to cover the opening. The light emitting member includes a flexible circuit board and plural light sources, the light sources are arranged spaced apart on the flexible circuit board, the light of the light sources of the light emitting member are focused on the light transmission cover through reflection by the light reflection surface, and finally projected out of the aluminum extrusion pipe after passing through the light transmission cover.

A projector. The projector comprises a projection light source, a first digital micro-mirror device, and a second digital micro-mirror device. The projection light source emits a projection beam toward the first digital micro-mirror device. The first digital micro-mirror device reflects the projection beam to the second digital micro-mirror device. A first micro-mirror on the first digital micro-mirror device is rotated in a horizontal direction to adjust the horizontal position of the projection beam. The second digital micro-mirror device reflects the projection beam from the first digital micro-mirror device to a projection plate. Second micro-mirrors on the second digital micro-mirror device are rotated in a vertical direction to adjust the vertical position of the projection beam.

A press type lighter having a safety switch includes a clutch structure for controlling the press member and the flow of fuel gas from the liquid gas container to be disposed at a locking or free state. A control member is movably mounted in the receiving chamber of the press member, and has a bottom provided with a leg portion which has a bottom formed with a locking flange rested on a top edge of the liquid gas container. The press member is formed with a locking hole for locking the locking flange of the control member, thereby forming a first-stage safety switch structure by the locking flange and the locking hole, for locking the press member temporarily, so that the press member is locked on the liquid gas container.
