Abstract:
Disclosed is an assembled helical turbine system, which can strengthen weakenings of a housing assembly, and simultaneously can be easily assembled/disassembled. The assembled helical turbine system includes a helical turbine formed with a plurality of blades in such a manner as to continuously generate a rotational force under unidirectional or multidirectional fluid flow; the housing assembly including a plurality of bearing spiders for rotatably supporting a rotating shaft constituting the helical turbine, and a plurality of side posts for connecting and fixing the respective bearing spiders to each other, the side posts being fixed in such a manner as to radially protrude by a predetermined length from peripheral surfaces of the bearing spiders; filling members for filling and reinforcing spaces between the peripheral surfaces of the bearing spiders and outlines of protruding portions of the side posts; and a housing supporter for supporting the housing assembly in such a manner that the housing assembly can be inserted into and withdrawn from the housing supporter, the housing supporter having catch grooves that are recessed in a shape corresponding to stoppers, that is, the protruding portions of the side posts, so as to fix the stoppers. In this way, the weakenings generated in portions where the bearing spiders are joined to the side posts can be reinforced by the filling members, and thus the portions where the weakenings are generated can be strengthened.
Abstract:
Disclosed is a method of manufacturing biodiesel fuel by using vegetable oil, wherein the method comprises the steps of: a) carrying out esterification of 25 to 33 wt% of diesel, 36 to 55 wt% of glycerin, 7 to 13 wt% of solvent oil, 8 to 13 wt% of Il-sun oil, and other additives in the presence of an acidic or basic catalyst; b) separating the esterification reaction product into layers by specific gravity difference in a settling tank through reaction at a driving pressure of 3 to 4 atm, at 70 to 8O0C, and removing a glycerin layer; c) filtering out non-esterified materials by a centrifugation process; and d) carrying out a reaction by using a vacuum evaporator in a batch reactor.
Abstract:
Disclosed is an anti-obesity active extract obtained from a medicinal plant. More specifically, the extract obtained from lysimachiae f oenum-graeci herba (which is a medicinal plant traditionally used in the East) can be used as an active ingredient for a raw material, a functional food, cosmetic, a crude drug, etc. for an obesity preventing or therapeutic agent because the extract can suppress the adipocyte differentiation and decrease the body weight and body fat in an obese animal, thereby suppressing fat accumulation (that is, a factor for obesity).
Abstract:
Disclosed is a system for interrupting an electric power of an outlet or closing a gas valve through detection of the absence of a user. The system includes a signal transmission device installed on an outside of the outlet and a gas valve device. The signal transmission device detects the existence of the user to output a control signal, and the outlet and the gas valve device receive the control signal to control the flow of an electric power or gas.
Abstract:
Disclosed is a method for downloading multimedia contents to an electronic picture frame. The present invention relates to a method for downloading multimedia contents to an electronic picture frame connected to a multimedia contents management server (hereinafter referred to as "management server") via a mobile communication network or a wire communication network, comprising the steps of A) classifying and storing the multimedia contents into a plurality of groups formed according to preference rating; B) extracting a predetermined number of multimedia contents to be downloaded to the electronic picture frame from the plurality of groups and generating a download list of the predetermined number of multimedia contents; C) transmitting the predetermined number of multimedia contents included in the download list to the electronic picture frame; D) when the downloading is completed, storing the time of downloading the predetermined number of multimedia contents for each of the predetermined number of multimedia contents; and E) when a predetermined requirement is satisfied in the management server, performing steps B) to D) repeatedly.
Abstract:
Disclosed is an apparatus for shifting the center of gravity of a vehicle having three wheels or more, which includes: a fixed chassis part on which at least one fixed rail part shaped like a circular arc having its origin at one point on a virtual line obtained by projecting the vertical center line of the vehicle body on the ground is included; a movable chassis part in which at least one movable rail part movably assembled in the left/right direction relative to the vertical direction of the vehicle body along the fixed rail part is included; and a control unit for shifting the center of gravity of the vehicle body so as to shift the center of gravity of the vehicle body as needed by controlling a shift of the movable rail part of the movable chassis part relative to the fixed rail part of the fixed chassis part. According to the apparatus for shifting the center of gravity of a vehicle having three wheels or more requiring the shifting of the center of gravity to the left/right relative to the driving direction, upon driving of the vehicle, the center of gravity is shifted and restored more easily, effectively, and precisely, and upon stopping, the left/right movement is precisely controlled. In addition, the apparatus can prevent a tire thereof from wearing and secure safe driving.
