Abstract:
A displacement type generator including a magnet set and a coil set is provided. The magnet set includes a magnet with unidirectional magnetization and a first multi-polar magnetic structure, wherein the first multi-polar magnetic structure is disposed on the magnet. The coil set includes a magnetic center pole, a coil and a second multi-polar magnetic structure. The coil is wound on the magnetic center pole. The second multi-polar magnetic structure is disposed on the magnetic center pole and is adjacent to the first multi-polar magnetic structure. As a relative movement is generated between the magnet set and the coil set, the magnetic flux changes and causes the coil to output an induced voltage.

Abstract:
In the penetration step, a carbon dioxide fluid is contacted to a sample of coffee green bean inside a chamber at a temperature of 28-50° C. and a pressure of 950-3,500 psi for 3-30 minutes to allow the carbon dioxide fluid to penetrate into the sample of coffee green bean. In a pressure relief step, the pressure in the chamber is reduced to normal pressure in a time period of 2-15 minutes, allowing the carbon dioxide fluid penetrated into the sample of coffee green bean to break down cell wall of the sample of coffee green bean to obtain a sample of coffee green bean with broken cell wall.
Abstract:
A multifunctional torch light includes a tube body, a barrel, a lightening assembly, a moveable sleeve, a lens assembly, a battery assembly, and a switch. Therein, the tube body has a first end and a second end. The barrel is disposed on the first end. The lightening assembly is fixed on the barrel. The moveable sleeve is rotatably disposed on the periphery of the barrel. The lens assembly is disposed on one end of the moveable sleeve and able to move in accordance with the moveable sleeve. The battery assembly is disposed inside the tube body and electrically connected to the lightening assembly. The switch is disposed on the second end of the tube body for being electrically connected to the battery assembly. Therefore, by adjusting the distance between the moveable sleeve and the barrel, wide-range diffusive illumination and long-distance concentrative illumination are both achievable.
