Abstract: A method for producing monosaccharides from algae includes (a) treating algae-containing water using an electrocoagulation device having an iron-based anode to induce flocculation of algae so as to obtain flocculated algae which have a trace amount of iron derived from the iron-based anode, (b) collecting the flocculated algae from the algae-containing water, and (c) subjecting the flocculated algae to an acid hydrolysis reaction in an acid solution to obtain monosaccharides. A liquid-to-solid ratio of a volume of the acid solution to a solid content of the flocculated algae is not less than 12 ml/g. The acid solution has an acid concentration not less than 3% by volume.

Abstract: A float assembly means that includes platform consisting of a plurality of floats adjoined to float on the surface of a body of water; a bottom base below the water surface consisting of a plurality of floats adjoined that are submerged in the water; and a surrounding wall disposed between the platform and the bottom base consisting of a plurality of floats stacked together that are submerged in the water. The surrounding wall is formed of a plurality of wall surfaces, each wall surface collectively closing off a sealed area. The sealed area, at its lower extent, is closured by the bottom base and an opening is formed over the recess in its upper extent. The resulting structure is capable of, on a water surface, covering a specific body of water to form a safe swimming and water recreation area.

Abstract: A float structure having supplementary floating bodies that is comprised of a cavitary body, the hollow internal aspect of which enables buoyance and floatation in water, and a plurality of floating bodies disposed within the cavitary body. Given such a structure, when a float, containing the plurality of floating bodies in its cavitary body, incurs collision and wear damage that results in leakage and a loss of the floating body capability it should possess, the supplementation provided by the invention herein constitutes another source of buoyance that supports the entire float in retaining a major portion of its buoyance, thereby preventing the float from sinking and maintaining a set buoyant force.

Abstract: A float structure comprised of a cavitary body consisting of a hollow internal section, the cavitary body having disposed on it a first conjoinment structure and a second conjoinment structure. As such, when two floats of the invention herein are stacked into an assemblage, the first conjoinment structure of the rear float is inserted into the second conjoinment structure of the front float to thereby enable the connective assembly of the two floats.

Abstract: A container and container fabrication die comprised of a cylindrical body having a bottom section and, furthermore, an opening shaped at its upper extent, and a rim along the circumference of the opening. The rim is shaped at the inner lateral end of a cylindrical body, and a holding slot is first formed from the cylindrical body. Then, after curving a circular surface, the rim is brought against the distended edge of the holding slot. The container is shaped with a first and a second set of paired half dies as well as a support column.

Abstract: A method for manufacturing a container. The method includes the steps of providing main body dies, passive dies, active dies and a supporting column, followed by providing a semi-solidified flexible material in a considerably solvent state in the form of a tubular blank that is positioned and squeezed on the supporting column. The dies are opened and closed so that the active dies will squeeze the blank against the supporting column. Air is blown into the blank to enable the blank to adhere onto a cavity-shaped wall that is surrounded by the main body dies, the passive dies and the active dies. Air blown into the blank is released and the active dies initiate a first movement upwardly in synchronization with the supporting column. The active dies link-up with the passive dies to conduct a second movement upwardly to enable the active dies to drive the blank to deform.

Abstract: A hollow form body having a first-level faceplate and a second-level faceplate, with an appropriately sized space formed in between the two faceplates and a pattern formed on the one of the faceplates. An arresting edge of an appropriate height extends from the outline of a pattern such that a recessed area is formed in the bottom section of the pattern by the arresting edge. The pattern is figured on the first-level faceplate. A thick section at the lower extent of the arresting edge of the pattern covers and fastens onto the first-level faceplate, with a section being exposed on the surface of the first-level faceplate. The first-level faceplate fits into the recessed area of the pattern unit itself formed by the arresting edge and a rib is formed where the first-level faceplate covers the arresting edge.

Abstract: A cored form surface pattern structure includes a cored form having a first face plate and a second face plate, with the second face plate from the first plate separated by a suitable interval and a pattern located in the said first face plate. The said pattern can consist of characters, trademarks or graphics. The outline profile of the aforementioned pattern is a beveled edge of an appropriate angle, with the slant oriented from the lower surface of the pattern towards a central area of the upper surface such that the slanted outline of the pattern is positioned by the compressive and coating action of the cored form face plate and only the upper surface of the pattern is shown.

Abstract: A fitter's trolley includes an elongated plate member, a number of casters mounted to the lower side face of the elongated plate member, and a drawer member mounted slidably to the lower side face of the elongated plate member. The elongated plate member of the fitter's trolley is formed of a front panel and a rear panel which is hinged to the front panel, so that the fitter's trolley can be folded when the front and rear panels are rotated toward each other.
