According to the prefabricated comprehensive pipe gallery, the arc side walls are adopted to optimize the stress of the comprehensive pipe gallery, the dead load and cost of the comprehensive pipe gallery are reduced, the durability of the comprehensive pipe gallery is improved, and the construction quality is easy to guarantee.

A method of fabricating a flash memory devices disclosed wherein, upon formation of sidewall oxide films, a regrown thickness of a screen oxide film is controlled. The width of an element isolation film is reduced by means of an etch process for removing the re-growth oxide film. This allows a floating gate space to be easily secured, and a thickness of the sidewall oxide films is reduced by means of a liner nitride film pre-treatment cleaning process. It is thus possible to secure the trench space, which facilitates gap-filling.

A composite sheet has confined flexibility and is used in a safety pneumatic tire which is self-supporting under zero inflation pressure. The composite sheet comprises a matrix of high modulus solid objects, low modulus material, and optionally a matrix of cords, the high modulus solid objects being assembled to form a mechanism which allows the composite sheet to bend easily within predetermined ranges and confines the composite sheet from further bending when the limits of the predetermined ranges are reached. The safety pneumatic tire comprises a pair of the composite sheets disposed at sidewall regions under a carcass and / or a layer of the composite sheet disposed above a belt package. A method of making the composite sheet includes forming a chain of the high modulus solid objects having a desired locking position.

Batch casting of rim sprockets for chain saws as particularly applied to larger rim sprockets experience undesired high scrap rate resulting from porosity and chip-out. The solution is to ensure flow of molten steel throughout solidification of the molten steel in the sprocket mold while retaining molten steel portals or gates of a size that permits breakaway of portal stems. Such enhances the cooling rate of the molten steel in the sprocket mold which was found beneficial. The objective of reduced scrap rate is thus accomplished by maintaining a ratio of mass to surface area of the sprockets being cast to no greater than about 4 grams of material to each square inch of surface area and alternatively provide through bores through the rim sprockets which additionally assist in wood chip removal. This design also reduces the material content which reduces the cost and weight of the product.
