Abstract:
PURPOSE: A friendly human body mouse using double injection is provided to form a hard main body and a soft auxiliary injection unit by using double injection. CONSTITUTION: A main body(110) includes a floor side, bodies(120,130), and a button unit(121). The floor side is connected to a supporting side. The button unit pressurizes internal operating elements of the bodies. An auxiliary injection unit(150) is formed on a pressurization location pressurizing the button unit. The auxiliary injection unit is doubly jetted with soft synthetic resin. Unevenness is formed on a connected side of the main body for increasing coherence with the auxiliary injection unit.
Abstract:
본 발명은 고강성 다중반사구조의 평판형 광생물 반응기용 케이스는 합성수지로 이루어지며 상호 결합되어 광생물을 배양하기 위한 배양공간과 상기 배양공간과 연결되는 연결구들을 형성하는 제 1,2케이스부재를 구비하며, 상기 제1,2케이스부재는 상부로부터 하부로 갈수록 간격이 좁아지며, 외광을 다중반사시켜 내부로의 광유입량을 증가시킬 수 있는 복수개의 수평 및 수직고강성부를 구비한다. 본 발명에 따른 광생물 반응기용 케이스는 수평 및 수직고강성부와 류발생부에 의해 미세조류로의 광조사효율을 높일 수 있으며, 구조적 강도를 향상시켜 배양액의 하중에 의한 변형을 최소화 할 수 있다.
Abstract:
본 발명은 배양공간 내로 유입되는 기체가 와류를 발생하여 미세조류를 순환시킴으로써 미세조류의 배양효율을 향상시킨 버블 순환구조를 갖는 미세조류 배양용 광생물 반응기에 관한 것이다. 본 발명의 일 실시예에 따른 미세조류 배양용 광생물 반응기는 내부에 미세 조류가 주입되어 배양될 수 있도록 배양공간이 마련된 배양패널 본체; 상기 배양패 널 본체의 하부에 상기 배양공간을 횡방향으로 관통되게 설치되어 유입된 기체를 토출하는 기체 공급관; 상기 배양패널 본체의 내측 벽에 횡방향으로 연장되며, 상 기 기체 공급관을 통해 공급된 기체의 상승 기류에 대해 와류를 일으킬 수 있도록 호형으로 형성된 적어도 하나 이상의 와류형성 격벽;을 구비하는 것을 특징으로 한 다.
Abstract:
The present invention relates to a wheel for a crawler which prevents the crawler from falling down when the crawler moves in a pipeline and for easily changing tires, and the crawler having the same. The invention comprises a body (2002); a shaft (1002) installed on the bottom of the body (2002) at a specific distance; a wheel (1000) which is installed in the shaft (1002) and moves the body (2002), a control unit (2008) installed in one side of the body (2002) which controls the crawler according to a set program; a left gyroscope (2012) which is installed at the left upper side of the body (2002) and electrically connected to the control unit (2008) in order to sense the left angle of the body (2002) according to control signals from the control unit (2008) when the body moves in the pipeline; and a right gyroscope (2014) which is installed at the right upper side of the body and electrically connected to the control unit (2008) in order to sense the right angle of the body (200) according to the control signals from the control unit (2008) when the body (2002) moves in the pipeline.
Abstract:
PURPOSE: An electrolytic polishing apparatus is provided to efficiently fix an object to be polished and to easily polish the inside surface of the object to be polished. CONSTITUTION: An electrolytic polishing apparatus comprises an electrolytic bath (110), a water tank (120), a pump (150), an electrode member, and a current controller (180). The electrolytic bath has one side which has an inlet into which an electrolyte flows and the other side through which the electrolyte is discharged. The water tank stores the electrolyte which is discharged from the electrolytic bath. The pump pumps the electrolyte which is stored in the water tank to be injected through the inlet into the electrolytic bath. The electrode member is faced with the object to be polished. The current controller applies a pulse current to the object to be polished. [Reference numerals] (170) Controller; (180) Current controller; (AA) Power supply unit
Abstract:
PURPOSE: A photo-bioreactor with a bubble circulating structure for culturing microalgae is provided to enhance gas retention time in a culturing space and to uniformize optical absorption condition of the microalgae. CONSTITUTION: A photo-bioreactor(100) comprises a culture panel main body(110), a gas supply tube(120), and first and second vortex forming partitions. The culture panel main body is formed in a square shape and has a culturing space for culturing the microalgae. The culture panel main body comprises a rectangular main body(112), and front(113) and rear(114) covers which form a closed culturing space. A support rib is coupled between connection parts and prevents the main body from being twisted.
