Abstract:
A connection plug for a portable device is configured such that a single case is provided with different kinds of plug connection terminal units, which allows the single connection plug to perform functions of two kinds of connection plugs. The connection plug includes a case having an upper plug connection terminal unit and a lower plug connection terminal unit which are spaced apart from each other and disposed along upper and lower portions of the case respectively.
Abstract:
A piezoelectric vibration device for a mobile terminal is disclosed. A bimorph piezoelectric vibrator includes a pair of piezoelectric element layers connected to one of positive and negative poles and a middle electrode plate interposed between the piezoelectric element layers and connected to the other pole. The piezoelectric vibrator generates vibration due to up/down bending displacement by fixing both end portions thereof to an inner surface of a casing of a mobile terminal. A voltage-boosting transformer raises a power source voltage of a mobile terminal to a driving voltage. A driving chip receives the raised driving voltage from the voltage-boosting transformer and drives the piezoelectric vibrator. Weights are attached to at least one of both sides of the piezoelectric vibrator to amplify vibration. Insulation members are provided at both end portions of the piezoelectric vibrator to prevent electricity applied to the piezoelectric vibrator from leaking to the casing.
Abstract:
A card mounting socket for a mobile phone having a reduced size and reduced number of parts. The card mounting socket having a body and a separate casing. The body housing includes a first receiving section, a second receiving section and an inner wall. The first receiving section is provided with a pair of guides positioned on both sides thereof and a first card terminal disposed along a major surface of the first receiving section. The second receiving section includes a second card terminal disposed along a major surface of the second receiving section. The inner wall extends perpendicular from the first receiving section to the second receiving section such that the second receiving section is stepped with respect to the first receiving section. The separate casing is secured to an upper portion of the body and separates the first receiving section from the second receiving section.
Abstract:
The present invention relates to a method of successively producing D-psicose from D-fructose or D-glucose by using a psicose-epimerase derived from Agrobacterium tumefaciens which is expressed in a food safety form.

Abstract:
Provided is a separator for a rechargeable lithium battery including a porous support including a polymer derived from polyamic acid or a polymer derived from polyimide, wherein the polyamic acid and the polyimide include a repeating unit prepared from aromatic diamine including at least one ortho-positioned functional group relative to an amine group and dianhydride.
Abstract:
The present invention relates to a method for producing tagatose using soy oligosaccharide or soluble sugar solution containing the same, more precisely, a method for producing tagatose comprising the following steps; hydrolyzing soy oligosaccharide by using α-galactosidase selectively; producing tagatose continuously by enzymatic isomerization of galactose obtained from the hydrolysate; separating the produced tagatose by chromatography; and recycling the non-reacted materials.
