Abstract:
A power generator using a permanent magnet is provided to transfer a rotation force as a power source to other devices by acquiring the power through a rotor rotated by a repulsive force of the permanent magnet. A power generator using a permanent magnet includes a bar type permanent magnet plate(10) and a ring type permanent magnet plate(30). The bar type permanent magnet plate(10) has different polarities on a front plane and a rear plane at an outer part of a non-magnetic circular plate. A part deviated from a central part of the bar type permanent magnet plate(10) is matched with a part where a circle and a tangential line of the ring type permanent magnet plate(30) meet each other. The bar type permanent magnet plate(10) is formed to have the same length upward/downward along the tangential line. The bar type permanent magnet plate(10) has the non-magnetic circular pate which is formed along a circumference of at least one circle. A diameter of the non-magnetic circular plate is the same as a diameter of the ring type permanent magnet plate(30). The circular plate having the ring type permanent magnet plate(30) is fixed. A rotation plate having the bar type permanent magnet(10) is rotated. The ring type permanent magnet plate(30) is connected to the circular plate having the bar type permanent magnet plate(10).
Abstract:
The present invention relates to a heat engine comprising a cylinder unit and a piston unit in which a piston and a first connecting rod of the piston are formed in one cylinder chamber, the first connecting rod reciprocating through a hole which is made not to allow air to leak from one side wall of the cylinder chamber, a valve unit in which both ends of the inside of a closed cylinder chamber have a hole through which air can enter and exit and a valve capable of opening and closing the hole, and a heating unit for heating a cylinder by means of heating coils or gas flames. The cylinder chamber is divided into two chambers, and the piston reciprocates by means of a control unit for controlling the opening and closing of the valve, which is alternately closed to a cylinder chamber in which the air is heated, and is opened to an opposite cylinder chamber from which the air exits.
Abstract:
A coupler made of a flexibly bendable material is coupled to a bolt and a nut through a protruding part and a groove, and the protruding part or the groove is formed at both sides of each of the bolt and the nut such that the bolt and the nut are not loosened without intentionally applying great force.
Abstract:
Method for manufacturing silk peptide is disclosed. The method according to the present prepares 40 ~ 60% of CaC12 solution using food grade CaC12 and purified water. And then solubilizes cocoon by inputting the cocoon into the CaC12 solution, and dilutes the CaC12 solution by inputting 150±10% of purified water with respect to the solution by weight ratio into the solubilized solution, filtering, desalinating, and sterilizing the diluted solution. And then adjusts the pH using food grade acetic acid or sodium acetate, inputting protease-N solubilized with pufifying water into the solution, and hydrolizing it a certain time. According to the present invention, it is able to reduce possibility of fire and/or water polution might be happened in case of the conventional silk peptide manufacturing method using ethanol in solubilization step, and also manufacturing cost could be reduced.
Abstract:
Disclosed is a power generator using a permanent magnet. A power generator rotates with torque on the rotatable permanent plate by gradient of the fan and generating the power by forming the fan-shaped permanent magnet plate at different polarities on a front and rear sides, respectively, fixing the fan and disposing the rotatable permanent magnet plate having the same polarity as the front side of the fan is disposed in front of the fan, by use of a permanent magnet which includes a rotor having a magnetic property of generating a repulsive force when identical polarities approach between magnetic bodies.
Abstract:
The present invention relates to a method of treating a surface comprising a silicone elastomer having a plurality of Si-H groups by contacting at least one region of the surface with a solution comprising a surface treatment compound, to give a treated surface with Si-OH, Si-OR, or Si-C groups. The present invention relates to a hydrosilylation-curable silicone composition. In some examples, the hydrosilylation-curable silicone composition includes an organohydrogen-polysiloxane having an average of at least forty silicon-bonded hydrogen atoms per molecule, a cross-linking agent having an average of at least two aliphatic unsaturated carbon-carbon bonds per molecule, and a hydrosilylation catalyst, wherein the mole ratio of silicon-bonded hydrogen atoms in the composition to aliphatic unsaturated carbon-carbon bonds in the composition is at least 20:1. The invention also relates to membranes, methods of making membranes, gas permeable supports for membranes, and methods of gas separation using membranes.
