A multi-functional table comprises an adjustable second support surface recessed below the upper support surface which extends outward therefrom for use as by a person seated adjacent to the table. When not in use, the second support surface is stored beneath the upper support surface of the table, requiring no additional storage or space requirements for the second support surface.

The invention discloses a quantifying device which comprises a container for holding a powdery substance or a colloidal substance. A base opened in the lower side is arranged at the bottom of the container, a storage cavity is formed in the base, a substance inlet through which the substance in the container falls into a storage cavity from the top of the storage cavity is formed in the bottom ofthe container, a substance outlet through which the substance in the storage cavity falls out from the bottom of the storage cavity is formed in the base, and a pulling part capable of pushing and pulling from the lateral side is arranged on the base. The storage cavity communicates to the substance inlet and the storage cavity and the substance outlet are closed by pulling or pushing the pullingpart, so that the substance in the container falls into the storage cavity. The pulling part is pushed and pulled in the reverse direction, so that the storage cavity and the substance inlet are closed while the storage cavity communicates to the substance outlet. The substance in the substance storage cavity falls out from the substance outlet to be taken, so that the substance in the container is taken quantitively. The condition that hands stretch into the container is avoided and the substance in the container is prevented from being polluted. The quantifying device is simple and convenient to operate.

The present invention relates to a valve for controlling fluids with an improved flow behaviour, comprising a valve element (2) with a through opening (4) and a valve seat (5), wherein the valve seat (5) is formed on a first conical region (6) of the valve element (2), and a closing element (3) which opens and closes the through opening (4) at the valve seat (5), wherein the through opening (4) has a shape which widens in the flow direction (H).

The invention provides an auxiliary device for training sea lions to salvage marking and a using method thereof. The auxiliary device includes a base, a sleeve, a release mechanism, a steel cable, a thimble cylinder, a sliding induction baffle and an underwater target model; wherein the sleeve includes a support sleeve, a release sleeve and a threaded cover, and the release mechanism includes a spring, Slide peg, push arm and fixed base. The base is connected to the support sleeve, one end of the threaded cover is connected to the support sleeve, and the other end is connected to the release sleeve; one end of the thimble cylinder is connected to the release sleeve, and the other end is connected to the push arm; the push arm The other end is respectively connected with the spring and the sliding bolt, the other end of the sliding bolt is connected with the sliding induction baffle, and the two sides of the fixed base are fixedly connected with the inner wall of the supporting sleeve. The auxiliary device of the present invention is simple in structure, easy to use, can improve the success rate of sea lion underwater marking training, has high reliability and strong sense of comfort.

Said invention also refers LCD and assembling method using said invention.

This invention realizes the PHS wireless dividing data transmission method, which uses X.25 agreement to realize dividing by use of multiple channels to point PPP to adapt PHS wireless dividing data; mobile adapting module is located between the PPP and X.25 SVC virtual circuit by isolation; in the terminal mobile process, switching from A to B with MAL layer released by the virtual circuit; in the process, the MAL layer using new SVC to take place of old SVC to ensure upper layer connection of PPP.

The invention discloses a layer-stranded optical fiber ribbon cable and its production process, which includes a loose tube and an optical fiber unit installed in the loose tube, a central strengthening member is placed inside the stranded loose tubes, and a water blocking belt is placed outside , a metal ribbon and a sheath layer, the optical fiber unit includes a multi-layer bendable optical fiber ribbon, the bendable optical fiber ribbon is a continuous and alternate arrangement of optical fiber bundles and adhesive layers, and the optical fiber bundle is at least two optical fibers passing through The photocurable resin is UV-cured and formed together, and the adhesive layer is a hot-melt adhesive resin layer continuously coated between the optical fiber bundles, so that the optical fiber bundles can be bent along the axial direction of the adhesive layer. The layer-stranded optical fiber ribbon cable prepared by the present invention, because the optical fiber bundle has bendability and mobility in the optical fiber ribbon, thereby improving the duty cycle of the optical fiber in the loose tube and the fiber packing density of the optical fiber in the optical cable, and can reduce the fiber density at the same time. The outer diameter of the optical cable is small, reducing the weight of the optical cable itself, which is beneficial to saving the installation and welding time of the optical fiber ribbon optical cable, and improving the installation and laying efficiency of the optical cable.

The invention relates to the technical field of medical appliances, and discloses a gastric tube for patients after gastrointestinal surgery. The gastric tube used for patients after gastrointestinal surgery includes a gastric tube body and a nasal cover, the gastric tube body includes a rolling device, the nasal cover includes thirty-eight air holes, a fixing device, a mounting device and a clamping device, the air hole is opened on the front of the nose cover, the right side of the rolling device is fixedly connected to the left side of the gastric tube body, the top of the installation device is fixedly connected to the bottom of the nose cover, and the fixing device includes the first A rope, a second rope, a cloth strip, a mouth, a first Velcro and a second Velcro, the right side of the first rope is fixedly connected to the left side of the nose cover. By setting the first rope, the second rope, the cloth strip, the opening, the first Velcro and the second Velcro, the stomach tube for patients after gastrointestinal surgery solves the effect of adhesive tape fixing the gastric tube bad question.
