The venturi scrubbers 3, 4 recover a pollutant molecule contained in the gas as a solvent by making an air current and a water current cross with each other. Therefore, a pollutant contained in an exhaust is adsorbed and captured by water the gas passes through an aqueous cost formed by ejecting the water from a high pressure centrifugal spray nozzle 8. And an acidic solution thus obtained is neutralized in a neutralization tank 10 and the pollutant is precipitated to the bottom part as sludge.

Title: Modified wooden fiber-plate and its manufacture
Inventor: HONDA TOMIYASU
IPC: B27N3/04
Filed: 1990-10-30
Abstract: PURPOSE:To produce the wooden fiber-plate excellent in the dimension stability by a method in which the specified amount of water resistant sizing agent is added to the wooden fiber in which the hydroxy group in the wooden fiber is made to react up to a specified acetylation rate by acetylation reaction, and they are press-molded through an adhesive. CONSTITUTION:The water resistant sizing agent of 0.5-5wt.% is added to the wooden fiber in which the hydroxy group in the wooden fiber is reacted to the acetylation rate of 5-10% by acetylation reaction, and they are molded through an adhesive. Since the acetyl-treated wooden fiber approaches lipophilic nature, even if the water resistant agent is added to 5wt.%, it is not only stuck to the surface of the wooden fiber, but also it permeates inside thereof, therefore the amount of the sizing agent does not become excessive, and its water resistance is improved. As the adhesive, the synthetic resin adhesive such as urea resin adhesive or phenol resin adhesive, etc., is preferably used. the adhesive amount to be added is 10-15wt.% to the wooden fiber, and its resin retension rate is 30-60%. The wooden fiber to which the adhesive is stuck, is sent by wind pressure through a duct and is made into the fiber mat of constant thickness by forming and it is hot press-molded by means of a hot press.

Title: Bearing support structure of rotary shaft and motor
Inventor: OKETANI TETSUYA
IPC: F16C35/077
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To restrain a creep and support the rotation of a rotary shaft smoothly by push-pressing so as to oppose to the maximum force for moving an outer race in a radius direction by the rotation of the rotary shaft from the radius direction outside while allowing the axial direction movement of the outer race and pressing the outer race against a bearing support hole. SOLUTION: In a spring holding hole 22, a compression coil spring 23 is interposed between a corresponding outer race 14a and a groove bottom 20 as push-press means and the spring force of the compression coil spring 23 is exerted from a radius direction outside toward the center of a bearing for the outer periphery surface of the outer race 14a. When a rotary shaft 25 is rotated, a spring force is set to a larger force than the maximum force generated in the lateral direction of the outer race 14a and the play of the outer race 14a is prevented by opposing, even if the maximum force generates in the radius direction of the outer race 14a. The outer race 14a is pushed against a connection point of a hollow part 11b and a cylindrical hole part.  Thereby, the outer race 14a restrains a creep rotated at very slow speed in a reverse direction and the rotary shaft 25 can be rotated smoothly.
