Disclosed is a liquid container adapted to store liquefied natural gas (LNG). The LNG storage container include a sealing wall directly contacting liquid contained in the tank and a structural wall, which is an exterior wall or inner structure integrated with the exterior wall. The container further includes a plurality of connectors mechanically connecting the sealing wall and the structural wall and an intermediate wall structure positioned between the structural wall and the interior wall. The intermediate wall structure is configured to move relative to at least one of the interior wall and the structural wall

A stereo speaker system including: a speaker unit having a plurality of speakers which output audio; and a filter unit selectively receiving low frequency components of the outputted audio. The filter unit eliminates the received low frequency components to decrease back pressure on the speakers. Thus, the phenomenon of air-loading caused by back-pressure is removed and the low frequency characteristic of stereo speakers is improved by activating the vibration of a vibrating plate.

An EMI (electromagnetic interference) shielding film of a flat panel display device includes a mesh unit formed of conductive meshes that are intersected with each other, and a mesh frame for surrounding the mesh unit to support the mesh unit and to define an effective display area on a screen. Both the mesh unit and the mesh frame are formed integrally together by a base film which has PET (polyethylene terephthalate) and metal foil.

Disclosed is a portable terminal including a slide keypad for conveniently inputting data. The portable terminal includes a body, a display unit connected to the body through a swivel hinge unit to open/close an upper surface of the body or to be located parallel to the body along the lengthwise direction of the body, a fixed keypad installed in the body and a movable keypad moved so as to be close to or far away from the fixed keypad with the movable keypad facing the fixed key pad, moved with the movable keypad facing the body, and opened or closed by the rotation of the display unit or by self-movement. The movable keypad slides to be used even when the body is closed by the display unit, or the fixed keypad and the movable keypad are used together by the rotation of the display unit.

A multi-functional child care storage includes a plurality of functional compartments. The plurality of the functional compartments includes a steam sterilizing compartment for sterilizing an infant product loaded therein. The steam sterilizing compartment has a sterilizing space arranged in the main body for sterilizing the stored infant product; an evaporation vessel arranged inside the sterilizing space for containing water therein; a heater installed under the evaporation vessel for heating the evaporation vessel to evaporate the water contained therein into steam; an exhaust outlet through which air in the sterilizing space is exhausted to an outside; a blower for generating an air flow for exhausting the air in the sterilizing space through the exhaust outlet; and a control unit for controlling the blower and the heater to start, suspend or resume operations thereof depending on a temperature of the heater.

A lens edger which is capable of measuring the curvature of an eyeglass lens is disclosed. The lens edger includes a carriage which rotatably fixes a pair of lens fixing shafts and moves the position of the lens fixing shafts clamping a lens to be processed; a lens rotation motor for rotating the lens fixing shafts; a carriage driving means for moving the carriage; and an apparatus for measuring a curvature of the lens. The apparatus for measuring lens curvature includes a curvature tracer which contacts with a side of the lens and detects a curvature of the lens by moving horizontally according to the curvature of the lens during a rotation of the lens; a curvature tracer rotator which rotates the curvature tracer to a position for measuring the lens curvature, and to which one end of the curvature tracer is inserted in a manner of allowing sliding movement of the curvature tracer in a horizontal direction; and a slider base which guides the movement of the curvature tracer in the horizontal direction, and provides a restoring force to the curvature tracer so that the lens and the curvature tracer can be maintained in a contacted state.
摘要:
A permanent-magnet motor including a rotor having permanent magnets disposed therein, and a stator, wherein an outer circumferential surface of the rotor is opposite to an inner circumferential surface of the stator, and one or both of the outer circumferential surface of the rotor and the inner circumferential surface of the stator are varied in a radial direction so as to provide a non-uniform gap between the two surfaces to approximate sinusoidal change in magnetic flux.
