Abstract: A method for producing amorphous silica includes: a pretreatment process of pulverizing vegetable material to obtain a silica source; a burning process of burning the silica source and extracting silica; and a purification process of removing carbon from burning material obtained in the burning process. The burning process includes a heating process of supplying an inert gas into a chamber and heating the silica source in the chamber in a plasma atmosphere.

Abstract: The present invention provides a light transmittable and tissue integration integrable biofiber device including a plurality of biofibers. The plurality of biofibers consist a single bare fiber or a single constructed fiber. The single constructed fiber consists a core layer and either a single cladding layer or a plurality of cladding layers, and the cladding layer clads and fuses a circumferential surface of the core layer. Each of the plurality of biofibers comprises a light receiving end and a light emitting end, a light radiates through the light receiving end and the light is emitted from the a light emitting end. Therefore, the biofiber device of the present invention may simultaneously accomplish light transmittable and tissue integrable purposes to facilitate light therapy, optical gene therapy and optogenetics.

Abstract: A hammer has a main unit. The main unit has a handle, a striking head, and a nail puller. The handle has a lengthwise direction, a first end, and a second end. The first end of the handle and the second end of the handle are opposite in the lengthwise direction of the handle. The striking head is disposed at the first end of the handle. The nail puller is disposed at the second end of the handle. The nail puller has a pulling unit with an opening for receiving a nail. The nail puller is thinner than the striking head and allows the hammer to be operated in a small space to remove a fixed nail.

Abstract: A machine for producing and dispensing bar products, such as frozen crushed-ice drink, hot beverages or the like.

Abstract: The disclosure discloses a Chinese meal package and a preparation method thereof. The Chinese meal package is prepared from the following raw materials in part by weight: a component A, a component B, a component C and a component D according to a ratio of 1 to 1 to 1 to 1.

Abstract: A hand tool has a handle, a first working portion, and a second working portion. The hand is elongated and has a top. The first working portion and the second working portion are detachably connected respectively with two ends of the top of the handle. Each one of the first working portion and the second working portion is made of a material different from a material of the handle.

Abstract: A rotor for a rotary cylinder includes a body having a tube and a plate which has the first end integrally formed to the tube, and the second end of the plate extends radially relative to the tube. The plate is a solid plate and has a curved outer periphery. A first recessed area is defined in each of the top and the bottom of the plate. A waist is formed to the plate and located between the first and second ends of the plate. A resilient coat is coated to the body and includes a Y-shaped seal portion along the curved outer periphery of the plate so as to be movably in contact with the inside of the cylinder.

Abstract: The present invention relates to methods and tools for discriminating between Vel negative and Vel positive phenotypes. The invention is thus useful for determining Vel blood group status of individuals about to receive blood transfusion.

Abstract: A quick-release device for screwdriver bit includes a shank having a polygonal hole longitudinally defined in one end thereof and adapted for partially receiving a bit. At least one slot is longitudinally defined in the shank. An annular groove is defined in an inner periphery of the polygonal hole and communicates with the at least one slot, wherein the annular groove is formed with a tapered section toward the first end of the shank. An expandable limit element is received in the annular groove. A sleeve is movably sleeved on the shank. The sleeve has at least one protrusion inwardly extending therefrom and engaged into the at least one slot and abutting against the limit element when removing the bit form the polygonal hole. A stopper is secured on one end of the shank for preventing the sleeve from removing from the shank.

Abstract: The invention relates to a compression device (1) for assisting x-ray examination of an object. The compression device (1) comprises a support plate (3) adapted to receive thereon the object to be examined; a compression plate (4); and a displacement device (5) arranged to interact with the support plate (3) and the compression plate (4) to allow modification of the spacing (A) between the support plate (3) and the compression plate (4) to compress the object there between. A plurality of pressure sensors (13) are distributed across the support plate (3) and/or the compression plate (4) for sensing local pressure distribution across the compression area of the compressed object. The displacement device (1) is arranged to set and adapt the spacing (A) between the support plate (3) and the compression plate (4) angularly and linearly as a result of the sensed local pressure distribution across the compression area.

Abstract: A vehicle wheel with self-rescue apparatus contains: a connecting disc and a winch device. The connecting disc includes a body, a protruded column, elongated locking orifices, fitting sleeves, through orifice, connection stems, and multiple fixing plates. Each locking orifice locks with each of plural nuts, and each connection stem has a tab and a threaded section for screwing with a screwing orifice on each fixing plate via one of the through orifices, and each fixing plate contacts with the wheel rim, after the threaded section screws with the screwing orifice via the one through orifice. The winch device includes a rolling disc, the accommodating opening, a passing opening, a cable, and a hooking portion. The rolling disc has the accommodating opening, and a profile of the accommodating opening corresponds to the protruded column, the rolling disc has the cable rolled thereon, and the cable has the hooking portion arranged thereon.
