A moving fluid energy recovery system for generating electricity through rotational motion produced by positioning the present invention in a fluid flow produced by nature or a moving vehicle. The moving fluid energy recovery system has first and second end plates, a plurality of elongated inner vanes, a plurality of elongated outer vanes, and shaft to drive an electricity generating device. The inner and outer vanes each have a substantially curved profile featuring a curve side and an open side. The first and second end plates each has a central bore defined therethrough, a plurality of inner vane slots each shaped to receive a corresponding inner vane, and a plurality of outer vane slots each shaped to receive a corresponding outer vane. The inner vane slots are orientated with the curve side toward the central bore, and the outer vane slots are orientated with the open side toward the central bore with the free ends of adjacent inner vanes positioned in the open side of the outer vane slots.

The present invention provides a highly-protective, heat dissipating LED light source module that may be waterproof or non-waterproof. In an embodiment, the present invention provides an LED light source module comprising: a waterproof housing comprising a metal substrate and a plastic cover integrally disposed on one or more surfaces of the metal substrate; and at least one light emitting diode, electronic component, and power line disposed on and operably connected with the metal substrate and encapsulated thereon by the plastic cover. In other embodiments are provided LED light source modules comprising: a circuit board with at least two through holes disposed at selected positions; at least one light emitting diode, electronic component, and power line disposed on the circuit board and operably connected therewith; and a plastic cover comprising at least two pins disposed and shaped for interconnection with corresponding through holes of the circuit board. The simple LED light source models disclosed may be efficiently and inexpensively produced and are capable of withstanding the harsh environments in which they are sometimes used.

An L-amino acid can be produced by culturing a bacterium which belongs to the Enterobacteriaceae family, and has an enhanced ability to use a fatty acid. The bacterium is capable of producing the L-amino acid in a culture medium containing a fatty acid or a hydrolysate of an oil-and-fat as a carbon source, thereby producing and accumulating the L-amino acid in a culture.

The invention relates to a ground peg (10) which is made from a steel tube (11) and comprises an upper cylindrical section (12), a lower section (16) that tapers towards the bottom to form a tip (14), and an external thread (26) that extends along at least part of the lower section (16) and is formed from a continuous sheet metal strip (28) welded onto an external surface (32) of the ground peg (10) by means of a continuous or regularly interrupted fillet weld (34). The external thread (26) has a nearly constant pitch (S) and slope (a) relative to a longitudinal axis (40) of the ground peg (10) along the entire length of the external thread (26). The invention further relates to a method or producing such a ground peg (10). In said method, the external thread (26) is laterally fed to the external surface (32) of the rotating steel tube as an elongate sheet metal strip (28) and is welded onto said external surface (32), the steel tube (11) being moved relative to the feeding point of the sheet metal strip (28) at a regular advance (V) in the longitudinal direction of the steel tube (11). The invention finally relates to a device for producing such a ground peg (10). Said device comprises a mechanism for clamping and rotating the steel tube as well as a mechanism (44) for feeding the sheet metal strip (28) to the external surface (32) of the steel tube (11) such that the sheet metal strip (28) tangentially rests there against.

The present invention relates to a method for producing 3-methyl-2-butenyl acetate which comprises reacting 3-methyl-2-buten-1-ol with acetic anhydride in the presence of an inorganic base catalyst and a method for producing purified 3-methyl-2-butenyl acetate which comprises subjecting crude 3-methyl-2-butenyl acetate to a step (A) of contacting it with an aqueous solution of an alkali metal hydrogen sulfite, or a step (B) of contacting it with an aqueous solution of a base, or both steps (A) and (B).

The present invention provides a method for producing an optically active N-(halopropyl)amino acid derivative, wherein the method comprises the steps of obtaining a compound represented by formula (III) by reacting an optically active alanine ester represented by formula (I) or a salt thereof (hereinafter sometimes simply referred to as an “alanine ester”) with a halogenated propane represented by formula (II); and obtaining an optically active N-(halopropyl)amino acid derivative represented by formula (IV) by introducing a protecting group onto the nitrogen atom of the compound represented by formula (III). The present invention provides a method for efficiently producing an optically active N-(halopropyl)amino acid derivative.
