Title: Device for washing pipe
Inventor: SHIN HYEON JUN
IPC: B08B5/00
Filed: 1998-12-30
Abstract: PURPOSE: A washer of piping using air waves is provided to secure more clean piping by supplying a media for washing and a sterilizer such as an ozone at the same time. CONSTITUTION: When a compressed air is generated in a compressor(2), the compressed air is temporarily stored inside a service tank(3) controlled under a certain set pressure. The compressed air is supplied to a first pneumatic valve(7) and a second pneumatic valve(8) during maintaining a pressure needed to a washing operation. The first pneumatic valve(7) generates shock waves by supplying air into a piping(16) during opening and closing a valve port with receiving an electric signal generated from a timer of a controller. The second pneumatic valve(8) converts a flowing direction of air. A speed controller(10) operates a rotary actuator(11) and the rotary actuator(11) supplies a media for washing and a sterilizer into the piping(16). Soft impurities such as a scale or a slime is exfoliated by supplying the shock waves, the media and the sterilizer through a check valve(15) into the piping(16) and by contacting in an inner face of the piping(16). The impurities are exfoliated again during contacting the media flowed into the inside of the piping by the shock waves of bubble and are exhausted to an outside with water.

Title: Ball joint type piston assembly having self-aligning function
Inventor: SEO SEUNG DON
IPC: F04B39/00
Filed: 1998-12-30
Abstract: PURPOSE: A piston is provided to conduct self-aligning and to reduce friction and abrasion caused by sliding parts by joining a connecting rod and the piston with a ball joint. CONSTITUTION: A connecting rod(130) and a piston(110) are out of line due to a common difference between the piton and a compressing chamber(161). A ball(120) moves to compensate the crossing part. The ball pushes an elastic plate(150) and an elastic unit(152) of the elastic plate keeps the ball on moving. Thus, a piston assembly(100) conducts self-aligning by the ball movement for compensating common difference of each sliding part.

Abstract: PURPOSE: A spin coating device and a photosensitive film coating method by using the same are provided to re-use most of a solvent which is used for cleaning a rear surface of a substrate by a drain separation plate which divides a discharge channel of the solvent into two parts, thereby minimizing a solvent waste amount and environmental pollution due to the solvent waste. CONSTITUTION: A spin coating device includes a chuck(50) to be laid with a substrate(52), a first nozzle mounted below the substrate around the chuck, a second nozzle(56) mounted on the substrate, a lower cup(58) surrounding a periphery of the chuck, an upper cup(60) separated from the whole lower cup and extended to a higher position than the substrate at an upper end, a drain separation plate(62) positioned between the upper and lower cups to be lifted to a height corresponding to the substrate or lowered down to the lower cup, and a piping coupled with an end of the drain separation plate.
