A passive cooling system of a nuclear power plant includes a steam generator, a cooling water storage tank, a water cooling heat exchanger, an air cooling heat exchanger, a divergence valve, and a cooling tower. The steam generator generates steam by heat exchange with a primary coolant system, and the cooling water storage tank stores cooling water therein. The water cooling heat exchanger is disposed in the cooling water storage tank, and the air cooling heat exchanger is connected to the steam generator. The divergence valve is controllable to divert steam from the steam generator into both the water cooling heat exchanger and the air cooling heat exchanger. Each of the cooling water storage tank, the water cooling heat exchanger, and the air cooling heat exchanger are located in the cooling tower.

Provided is a test tool for an airspeed indicator of an aircraft, including: a cylinder portion including an insertion groove with a predetermined amount of space, and of which one end is sealed by a cover and includes an injection portion on the cover so that the insertion groove passes through a pitot tube, and of which another open end includes a protruded step around its inner circumferential surface; a piston portion being inserted into the insertion groove to reciprocally move within the insertion groove, and including a protrusion portion having a size and a shape corresponding to an aperture of the insertion groove, and a bar-shaped knob portion being extended from the protrusion portion; and a display portion being formed of a transparent material on an outer surface of the cylinder portion to display a location of the protrusion portion reciprocally moving within the cylinder portion.
摘要:
The present invention relates to a therapeutic agent for ischemia which inhibits apoptosis under ischemic condition. The therapeutic agent of the present invention comprises antibacterial agents of quinolones, quinones, aminoglycosides or chloramphenicol as an active ingredient. Since the invented therapeutic agent improved the viability of cells under hypoxic and hypoglycemic condition, it can be clinically for ischemic diseases such as applied as a potential drug for ischemia-associated infarction and cerebral infarction.

Disclosed herein is a motor assembly for a vacuum cleaner, the motor assembly including: an inlet introducing air therethrough; a motor; an impeller installed on a shaft of the motor and including a plurality of blades disposed at predetermined intervals between a pair of plates facing each other so that it rotates by the motor to suck the air; a diffuser disposed at an outer side of a discharge hole formed at an edge of the impeller; a first fan including a plurality of blade parts disposed at predetermined intervals while having the shaft as a concentric axis and disposed beneath the diffuser; and an outlet discharging the air to the outside.
摘要:
Disclosed herein is a fan motor assembly. A motor includes a rotor unit and a stator unit. An impeller is provided on an upper end of a motor shaft of the motor. The impeller is rotated by the motor to suck air. The impeller includes a pair of plates that face each other, and a plurality of blades that are disposed between the plates at positions spaced apart from each other at regular intervals. A diffuser is disposed around an outlet formed in a periphery of the impeller. A motor housing encases the rotor unit and the stator unit therein. A sensing unit is provided on a lower end of the motor shaft that extends outwards from the motor housing. The sensing unit senses the rotation of the rotor unit. An inductor is installed in the motor housing.
