摘要:
Disclosed herein is a caseless projectile, in which a bullet head and a projectile body structure are fixedly arranged with each other. The caseless projectile can be fired in a barrel without a step of discharging the case; further, the caseless projectile's projectile bottom has a plurality of blade-shaped score lines. When fired, the score line are transformed into a plurality of nozzle structures by the impact force, so that the high-pressure gas generated by the burning of powder is ejected through the nozzle structures, further offering the caseless projectile a rotational torque and achieving the effect of accurate firing without rifling.

A mobile fire extinguishing device includes a motorbike having a base connected to a rear end thereof, and a foam-type fire extinguishing device is connected to the base. Two support units extend from two sides of the base respectively and each support unit has a retractable support rod. A support stand is pivotably connected to the rear end of the base and is positioned either at a retracted first position or an extended second position. When the two support rods are extended, the motorbike is lifted upward and the rear wheel of the motorbike is lifted from the ground. When the support stand is pivoted to the second position, the two support units are retracted, the support stand contacts against the ground so that the motorbike is stable on the ground to bear the reaction force due to the action of the foam-type fire extinguishing device.

A contactless volume control device with adjustable gain and multi-output is configured as a contactless structure with a magnetic slider and a plurality of magnet sensors. The magnetic field of the magnetic slider is sensed by the plurality of magnet sensors to generate a plurality of sensed signals, which allows an output module to provide a data table to show the position of the magnetic slider and the corresponding output voltage thereof according to the sensed signals. Furthermore, the output module is capable of storing multiple variable data to produce different outputs so as to achieve the objective of gain adjusting. Additionally, a processing unit built in the output module has a plurality of output ends so as to output multiple signals. And the magnetic slider and the plurality of magnet sensors have advantages of simple structure, easy manufacture and low cost.

A folding box includes a bottom board, two first folding board sets opposite to each other, two second folding board sets opposite to each other, and a mounting frame. Top sides of the first folding board sets are pivotably coupled to the first sidewalls of the mounting frame respectively. Bottom sides of the second folding board sets are pivotably coupled to the second sides of the bottom board. In use, the mounting frame is pulled up, bottom sides of the first folding board sets are locked to the opposite first sides of the bottom board respectively, top sides of the second folding board sets are locked to the opposite second sidewalls of the mounting frame respectively.
摘要:
The present invention relates to a vehicle composite reflection and refraction multi-imaging device including a reflecting surface, a semi-reflecting surface, and a concave lens. At least one image of at least one light source is reflected repeatedly by the semi-reflecting surface and the reflecting surface to form a plurality of visible mirror images on a mirror image side of the reflecting surface. The concave lens is disposed at the viewing side. A viewer at the viewing side views a plurality of visible mirror images at the mirror image side of the reflecting surface through the refracting of the concave lens. The reflected and refracted visible mirror images gradually shrink towards a vertical axis. Visible mirror images do not interfere with one another, and each visible mirror image is clear. The visible mirror images can generate an apparent inward-shrinking 3D effect of depth with levels.
