The laryngeal stroboscope includes a photography unit for photographing a patient's vocal cords and a light source for illuminating a part to be photographed, a microphone for sensing the patient's voice, a high-pass filter for passing voice signals of 100 Hz or more among voice signals output from the microphone, a low-pass filter for removing signals of harmonic components from the voice signals output from the high-pass filter and passing only a voice signal in a fundamental frequency band, a peak detector for detecting a peak of the voice signal output from the low-pass filter and obtaining a pitch, and a controller for controlling the light source to intermittently emit light in response to a signal output from the peak detector and controlling the photography unit to operate according to whether or not the light is intermittently emitted.

Abstract: It is about a power generating apparatus using fluid, which can obtain maximum power from natural energy with converted rectilinear motion into rotary motion, such as water. As the present invention, the apparatus using fluid includes; a bucket to put fluid in for loading itself; an Opening-and-shutting valve, which installed under the bucket to control the direction of water; a controller of opening and shutting, which connected with the opening-and-shutting valve for opening and shutting the valve; a motion converter, which connected with the bucket for convert rectilinear motion of the bucket into rotary motion; as well as subsidiary equipments for connection for connect the bucket to the motion converter.

Abstract: The present invention relates to a braking hydraulic circuit for linear pressure reduction of a front/rear wheel braking liquid pressure in a vehicle. On a liquid pressure return line formed between wheel cylinders and a master cylinder, a two-system liquid pressure control circuit separately passes liquid pressures to be discharged from the wheel cylinders and then unifies the liquid pressures. The liquid pressure control circuit has normal open type solenoid valves and normal close type solenoid valves. Therefore, at the time of implementation of ABS (Antilock Brake System) or TCS (Traction Control System), linear control of a front/rear wheel braking liquid pressure can be realized. In addition, a difference in pressure intensification gradient according to a difference in generation time between the front and rear wheels can be eliminated.

The method comprises treating acidic wastewater generated in the production of copper, zinc or titanium or the production of sodium hydroxide (caustic soda) and chlorine using saline water, with calcium hydroxide (slaked lime), so as to precipitate sludge, and mixing the precipitated sludge with pulp sludge ashes having pozzolanic properties.

Abstract: A solenoid valve for a slip control system in a vehicle is disclosed. A flow passage is provided in which working fluid such as oil that generates a break hydraulic pressure flows from the side of a solenoid valve through a filter, flows to the front of a plunger through a side hole formed in a valve body of the solenoid valve, and then flows along the side of valve body, that is, is discharged out of an outlet through a side space between valve body and a valve seat. Therefore, linear pressure control is easy because working fluid flows into toward the front of valve plunger through a side inlet of solenoid valve and the entire size is reduced because a special channel for guiding working fluid to the front of the valve plunger is not needed in a pump housing case.
