A bone fusion device provides stability to bones during a bone fusion period. The bones include, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable tabs attached to the bone fusion device by associated rotating means. The bone fusion device is preferably inserted by using an arthroscopic surgical procedure. During arthroscopic insertion of the device, the tabs are pre-configured for compactness. In this compact configuration, the tabs are preferably deposed along and/or within an exterior surface of the bone fusion device. After the bone fusion device has been positioned between the bones, one or more tab(s) are extended. In the preferred embodiment, the position of each tab is related to a positioning element and extending blocks. Typically, the tabs advantageously position and brace the bone fusion device in the confined space between the bones until the bones have fused.

The invention relates to a method for manufacturing a shoe part by injection moulding a material into a mould where an insert is placed. The insert comprises at least two separable insert parts, an upper insert part and a lower insert part, providing an injection channel in the region of the separation area between the two parts. The insert is placed in the chamber and the injection material is injected through a sprue channel in the mould into the injection channel and into a cavity, whereby the shoe part is formed. The mould is opened after the injection material has cured and the insert is separated into the upper and lower insert parts, thereby exposing the cured material in the injection channel.

The present invention relates to a method for synthesizing graphene/sulfur composite, involving the steps of mixing graphene oxide (GO) with a hydrogen sulfide (H₂S)-releasing agent in a sealed vessel, causing the H₂S-releasing agent to release hydrogen sulfide, and then allowing the hydrogen sulfide to react with the graphene oxide at an elevated temperature and pressure to form said graphene/sulfur composite.

Manufacture of a device having a body comprising a cavity with a fluid port made from an elastomeric material adhering to the body is disclosed. The device can be used advantageously in reliable analyses in automated procedures.

The invention discloses the reinforcement coagulate resin mortar casting tube and preparing method. The method comprises the following steps: 1 10-60% resin, 3.497-15% toughening agent, 1.5-6% plasticizing agent, 5- 80% quartz sand, 0.5-5% levelling agent, 40-3% curing agent, 0.5-5% accelerating agent, 0.003-5% defoaming agent; 2 mixing resin, plasticizing agent, quartz sand, levelling agent, curing agent and accelerating agent; 3 adding defoaming agent; 4 adding them into die with web tendon; 5 curing, stewing and mould unloading; 6 checking; 7 getting the reinforcement coagulate resin mortar casting tube. The tube is used as tube building material. The invention has the advantages of high strength, light weight, good sealing, corrosion prevention, long lifetime and low cost.

The present invention discloses a trench isolation structure, a production method thereof, a semiconductor device and an image sensor. The trench isolation structure comprises a shallow trench arranged in a substrate, an isolation material layer arranged in the shallow trench, and an epitaxial structure arranged between the shallow trench and the isolation material layer. The epitaxial structure comprises at least one epitaxial layer formed by in-situ doping. The epitaxial layer is formed by outward deposition of the inner wall of the shallow trench, a closed combined interface can be formed by the epitaxial layer and the inner surface of the shallow trench, and thus the leakage current generated by the combination part between the inner wall of the shallow trench and the epitaxial layer is avoided. At the same time, the composition or structure of the epitaxial layer can be changed through the mode of in-situ doping, thus the migration of a carrier in the epitaxial layer is reduced further, and the leakage in a semiconductor device is reduced further.

An adjustable applicator for applying a cosmetic or personal care composition, e.g. mascara to eyelashes or eyebrows. The adjustable applicator extends along a longitudinal axis and comprises of an applicator head, a stem, an inner rod and an actuator. The inner rod extending through the applicator head is capable of moving along a longitudinal axis of the adjustable applicator to cause progressive modification in shape of the applicator head by releasing and applying force on the applicator head.

The invention belongs to the technical field of tomato cultivation, and discloses a cultivating method for over-summer tomatoes in a greenhouse. The method comprises the steps of variety selection, cultivation of robust stocks and scions, grafting and management after the grafting, wherein the management after the grafting comprises the specific steps that grafted seedlings are placed in the plastic greenhouse under the airtight shading condition and watered with sufficient water, the air humidity is kept at 95% or above, the daytime temperature is 23-28 DEG C, and the temperature at night is15-22 DEG C; a plastic film is opened the next day, after three days, the air humidity is reduced to 76%-80%, the seedlings are exposed to light for 0.5-1 hour on the fourth day, for 1-2 hours on thefifth day and for 4-5 hours on the sixth day, from the seventh day, the seedlings are exposed to light all day, and after 7-8 days of wound healing, belts are loosened in time for transplanting the seedlings. According to the method, before sowing, disinfection treatment is conducted, harmful bacteria carried by seeds can be killed for preventing viruses, and the survival rate of the seeds is increased; grafting is conducted below cotyledons of the stocks, the grafting portions can be designed into trapezoid shapes, the contact area is large, and the survival rate is high.

The invention provides an aluminum-steel composite fastening disc. The aluminum-steel composite fastening disc is characterized in that an aluminum pipe and a steel bar are subjected to explosive cladding to form a metallurgical composite surface, then the metallurgical composite surface is cut to form the aluminum-steel composite fastening disc with an aluminum part and a steel part, a cross beamstructure with a fastening function is formed on the steel part through machining, and the aluminum part can be connected with other aluminum accessories through welding. The aluminum-steel compositefastening disc is high in strength, long in service life, high in corrosion resistance, simple and feasible in preparation steps, low in cost, good in application prospect and wide in application range.

The invention discloses a tomato grafting method. The method includes the steps of variety selection, robust stock cultivation, scion, grafting, post-grafting management and the like. From increase of survival rate of seeds to stock and scion preparation before grafting, grafting process and later-period maintenance, resistance of plants is improved, cell division is promoted, wound healing is accelerated, and grafted seedlings are enabled to resume growth. According to tomato seedlings cultivated according to the grafting method, bacterial wilt, root rot and root-knot nematode resistance performance of the plants can be improved by 80-90%, and survival rate of the grafted seedlings reaches above 98%.
