Abstract:
PURPOSE: A hydrogen detection sensor with an ultrasound movable unit which is length-adjustable and detachable is provided to install a sensor unit receiving ultrasonic signals to a piezoelectric element detachably, thereby improving user convenience. CONSTITUTION: A hydrogen detection sensor(100) with an ultrasound movable unit(130) which is length-adjustable and detachable comprises an electric signal device(110), a piezoelectric element(120), and an ultrasound moving distance adjusting unit(140). The electric signal device generates and detects electric signals. The piezoelectric element is connected to the electric signal device, thereby generating ultrasonic waves when the electric signals are applied. The ultrasound movable unit is connected to the piezoelectric element. A hydrogen sensitive material is spread on one surface of the ultrasound movable unit. The ultrasound moving distance adjusting unit is connected to one end of the piezoelectric element.

Abstract:
PURPOSE: An X-ray CT apparatus is provided to perform CT photography in real time by including a plurality of X-ray generators. CONSTITUTION: A plurality of X rays generating units(150) is separated from a subject by a certain interval. X ray detectors(160) is opposite to the X rays generating units while having the subject between. A data processing unit stores data extracted from the X ray detectors and generates tomography data based on data. A display unit shows a tomography image of the subject based on the signal of the data processing unit.
Abstract:
PURPOSE: An X rays video apparatus for reducing the interference effect of X rays due to the phase deviation and scattering is to be offered. CONSTITUTION: The X rays video apparatus(100) comprises the monochromator(106) which however extracts the back mirror(104), which reflects X rays created from source while being separately placed with the source(102), source occurring X rays and X rays which is reflected to the back mirror from the back mirror while being separately placed in X rays of wavelength.
Abstract:
A bending apparatus and a bending method are provided to form a three-dimensional truss formed in a shape similar to that of a Kagome truss from an expanded metal mesh, wherein the bending apparatus and the bending method are suitable for the mass production and are capable of performing an accurate forming process. In a bending apparatus comprising a pair of wedged male jigs(40) and a "V" shaped female jig(60) for pressing and bending a metal mesh such that "V" shaped irregularities are formed on the metal mesh, thereby forming the metal mesh into a three-dimensional truss shape, the bending apparatus is characterized in that a plurality of female bending blades(50) are inserted into the male jigs with the female bending blades being spaced from one another in a predetermined distance, and a plurality of male bending blades(70) engaged with the female bending blades are inserted into the female jig with the male bending blades being spaced from one another in a predetermined distance.
Abstract:
본 발명은 체내에 삽입되어 방향성을 갖는 카테터 헤드; 상기 카테터 헤드에 연결되어 컨트롤러부의 방향 제어를 전달하는 와이어; 및 상기 와이어에 연결되어 체외에 배치되고, 상기 와이어를 회전시켜 상기 체내로 삽입되는 카테터 헤드의 방향각을 제어하는 컨트롤러부를 포함하는 것을 특징으로 하는 능동형 카테터를 제공한다. 본 발명의 능동형 카테터에 따르면, 체외에 배치되는 컨트롤러부의 조작에 의해 체내로 삽입되는 카테터 헤드의 방향각을 쉽게 조절하여 카테터의 진행방향을 쉽게 결정할 수 있어 사용이 매우 용이하고, 정밀성 및 조작성이 뛰어나 정밀한 검사 및 치료가 이루어지며, 구조가 간단한 기계적 메커니즘으로 인하여 저가형 카테터를 제공할 수 있는 효과가 있다. 또한, 저가형 카테터를 제공함으로써 가격 부담없이 일회용으로 사용할 수 있게 되고, 일회용의 사용으로 환자에게 향상된 위생수준을 지원할 수 있으며, 이로 인하여 의료의 질적 수준을 향상시킬 수 있는 효과가 있다.
