Title: Honeycomb air filter and production thereof
Inventor: BESSHO NOBUYORI
IPC: D06M14/18
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To reduce the pressure drop in a parallel flow type filter and the weight of the filter and increase the rate of removal by forming a nonwoven or woven fabric of polymer fibers having ion exchange groups introduced by a radiation graft polymn. reaction into a honeycomb structure. SOLUTION: A nonwoven or woven fabric 1 of polymer fibers having ion exchange groups introduced by a radiation graft polymn. reaction is formed into a honeycomb structure to obtain the objective air filter adsorbing ionic substances. The honeycomb structure preferably has bonded parts each having 0.5-4mm width and openings each having 3-50mm<2> area and 2-5mm length of one side. Since ionic substances in the air are adsorbed by bringing the air into contact with the entire surface of the fabric formed into the honeycomb structure without passing the air through a nonwoven or woven fabric of ion exchange fibers, a small pressure drop and a high rate of removal can be attained.

Title: Nozzle head of rotary chip type air combination type airless gun
Inventor: SUZUKI KENICHIRO
IPC: B05B7/02
Filed: 1999-12-10
Abstract: PROBLEM TO BE SOLVED: To solve problems that the conventional air combination type airless gun operated by mixing atomizing air with a pressurized coating material jetted from a nozzle chip outside a nozzle chip is insufficient to eliminate the atomizing defect and the front surface or the like of an air cap is easily soiled due to the return of the coating material. SOLUTION: In a rotary chip type, air jetting ports 25 for atomizing are arranged just beside right and left with the interposed nozzle chip 11 having a long elliptic pattern and face to strike the atomizing air against each other near a coating material jetting port 11c of the nozzle chip 11. Then, the coating material jetted from the nozzle chip 11 receives the collision energy of the atomizing air from the initial time of the jetting to uniformly atomize the coating material over the whole jetting pattern to prevent the generation of tail. Because there is no room to produce a problem that the atomizing air flow strikes the particle of the coating material, the return or the scattering of the coating material is suppressed to prevent the soiling.
