The invention discloses a vehicle diverging traffic light and application thereof. The invention belongs to the traffic control field. According to the technical proposal of the invention, a first basic structure of the traffic light consists of a strip-shaped light, an arrowhead light and a dish-shaped light, wherein, four light bodies are manufactured to constitute a main light body for turningaround, turning left, driving straight ahead and turning right. A second basic structure is that the arrowhead light is manufactured into two light bodies for turning left and driving straight ahead.A third basic structure consists of a human-shaped light, a vehicle-shaped light, a left light and a right light, wherein, a walking and pushing vehicle and two front light bodies constitute an auxiliary light body. The lights are controlled by switches and six basic signal sources can be provided, thus forming a whole or separate vehicle diverging traffic light. The application signal of the traffic light can classify, diverge and control vehicles at intersections of urban highway through signals. The vehicles can be forced to diverge at peaks; divergence of vehicles can be controlled in a normal period; the vehicles drive naturally in a depressed period. In addition, the invention provides a novel signal option for intelligent or remote control of divergence and passing of vehicles, thus improving the passing security and capability of road intersections.

In the case of a cardan-joint shaft (1) comprising a first and a second jointed shaft portion (2, 3) and comprising bearing lugs (4) fastened in each case to a fastening region (7) of the first and second jointed shaft portions (2, 3) in particular by means of screw connections (8), which bearing lugs project in each case at one end beyond the respectively associated first or second jointed shaft portion (2, 3) and, in the projecting region (4a), hold between them a single-piece journal cross (6) which is mounted with in each case one journal (5) in an opening (10) of in each case one bearing lug (4), it is sought to provide a solution which permits the realisation of a cardan joint which is of compact construction and nevertheless permits the transmission of high torques. This is achieved in that each bearing lug (4), at least in regions, engages in a positively locking and force-transmitting manner into in each case one of two recesses (12) formed diametrically oppositely in the fastening region (7) in the outer surface, in particular circumferential surface, of the first and of the second jointed shaft portion (2, 3).

The invention relates to a securing device (1), which has a front hood (2) and a hood lock (3) with a lock holder (10), for a motor vehicle. The hood lock (3) has a rotary latch (4) with a pre-latching position and a main latching position in which the front hood (2) is closed and locked, an electric drive (5) which switches the rotary latch (4) from the main latching position into the pre-latching position, and a bayonet-type closure system (13) with a closed position, a release position, and an intermediate position. In the closed position, the rotary latch (4) is located in the main latching position; in the intermediate position, the rotary latch (4) is located in the pre-latching position and the lock holder (10) is engaged with the rotary latch (4); and in the release position, the lock holder (10) is released by the rotary latch (4) and the front hood (2) is unlocked.

The invention discloses a local plasma resonance refraction index sensor and a manufacturing method thereof. The local plasma resonance refraction index sensor comprises upper metal caps, medium columns and a lower metal aperture array, wherein the medium columns can be low-refractive-index dielectric media such as photoresist, and is positioned between the upper metal caps and the lower metal aperture array. According to the invention, through regulating an incidence angle, metal particles, the length of a period and particle lifting height, a figure of merit can reach 100; the local plasma resonance refraction index sensor can be widely applied to actual biochemistry sensing; and the preparation technique provided by the invention is simple, is low in cost, and is suitable for volume production.

The invention belongs to the technical field of a high polymer material and a biological material, and particularly relates to a water-soluble pore-foaming agent and a preparation method thereof, and a porous scaffold prepared from the pore-foaming agent. The pore-foaming agent disclosed by the invention comprises water-soluble particles which are prepared from salt such as sodium chloride and sugar taken as a binder in a bonding manner, and are spherical or similar to be spherical, and the surface of the pore-foaming agent has a topological structure. The water-soluble pore-foaming agent is simple in preparation process as well as convenient and practical; mesopores of the prepared scaffold are good in connectivity; and the topological structure in the pore-foaming agent can be transferred into the scaffold in the preparation of the three-dimensional porous scaffold, and thus, the surface topological shape on the surface of each hole of the three-dimensional porous scaffold is can be modified.

The invention provides a fluorine-free and washable one-way moisture guiding composite functional plus material. According to the scheme of the fluorine-free and washable one-way moisture guiding composite functional plus material, one-way moisture guiding and other complex functions can be obtained at the same time in one operation step. The fluorine-free and washable one-way moisture guiding composite functional plus material is proposed aiming at the problems that abundant fluorine-containing materials are used and the hazard to an environment is great in existing water-repellency technique and one-way moisture guiding technique and the phenomenon that a one-way moisture guiding plus material obtained in the prior art is quite poor in washability and durability. According to the scheme of the fluorine-free and washable one-way moisture guiding composite functional plus material, surface-hydrophobic microcapsules are formed; miniature bulges are constructed on one surface of the plus material. Besides that miniature liquid guiding passages needed by a one-way moisture guiding function are constructed, the plus material can be endowed with more functions by the microcapsules. Meanwhile, the fluorine-free and washable one-way moisture guiding composite functional plus material is wide in scope of application; the problems that the operation process is complicated and a one-way moisture guiding composite plus material with other function, which is widely applicable, cannot be obtained in the prior art are solved. The fluorine-free and washable one-way moisture guiding composite functional plus material can be used for a textile, clothing, shoes, a medical product, a mask, a cosmetic, storage, transportation, a container, a package, an electronic device, a building material, an apparatus and other product.
