Abstract:
A self magnetizing motor, in which a magnetic substance is disposed at the rotor and a stator is provided with a magnetizing portion to magnetize the magnetic substance, and the magnetizing portion forms an exciter pole protruding toward the magnetic substance and a tip portion tapered at an end of the exciter pole, wherein a width of the exciter pole, a protruding length of the tip portion, and a width of the tip portion are formed in the ratio of 8-9:2-2.5:1-2.4, thereby increasing the intensity of magnetizing of the magnetic substance thus to improve the motor performance.
Abstract:
Disclosed is a label having an ink layer which has a metal or a metal oxide as its pigment, the color of the metal or the metal oxide being changed with an oxidation reaction of the metal or the metal oxide by laser irradiation, the laser irradiation causing the oxidation reaction of the metal oxide so as to make the metal oxide change in its oxidation number or come to a complete oxidation state from an incomplete oxidation state.
Abstract:
There is provided a thermoelectric (TE) element. The TE element includes a plurality of pn junctions each formed by bonding an n-type TE semiconductor and a p-type TE semiconductor with a metallic layer interposed therebetween, and a first electrode and a second electrode electrically connected to the n-type TE semiconductor and the p-type TE semiconductor, respectively. The plurality of pn junctions are laminated with insulating layers interposed therebetween, and are connected electrically in parallel to each other. Even in the case that a section of components does not operate electrically, the operation of the entire element is not adversely affected, thereby improving stability of the TE element.
Abstract:
A clamping device includes an oblique device and a unidirectional load control plate disposed on the outside of the fuel cell stack, not on the inside of the fuel cell stack. The device can automatically compensating the surface pressure in the fuel cell stack to be maintained constant, and provide a large clamping load with a small force using the load of the fuel cell stack.
Abstract:
Provided is a method of storing a reagent in a microfluidic device. The reagent, in a liquid form, is loaded into reaction chambers arranged on the microfluidic device; followed by lyophilization as being contained in the microfluidic device.
