Title: Purifier for air
Inventor: ASAMI KINICHIROU
IPC: B03C3/155
Filed: 1981-03-12
Abstract: PURPOSE: To improve the capturing efficiency for particularly fine particles with reduced gaseous pressure drop by using a conductive porous metallic body having three-dimensional networklike skeleton as a dust precipitating electrode of an electrical dust precipitator, and placing this in the rear stage of discharge electrodes at a right angle to the gaseous flow.  
     CONSTITUTION: In an electrical dust precipitator for the purpose of capturing fine dust as a final filter for a clean room or the like of semiconductor factories, etc., a conductive porous metallic body 8 of a flat plate having three-dimensional networklike skeleton is used as a dust precipitating electrode, and this is disposed perpendicular to gaseous flow 4 so that gases are compelled to pass through the inside of the body 8. The preferable thickness of the body 8 is about 15W20mm. Discharge electrodes 2 are arranged at about 2W5cm forward of the body 8 and are applied with about 10,000W30,000 volts. Since the body 8 has a large surface area and small air flow passage resistance, it improves capturing efficiency for particularly fine particles (≤1 micron).

Abstract: PURPOSE:To eliminate lead distortion at the time of molding, and restrain lead flatness and lead bending after lead shaping in the range lower than or equal to allowable values, by regulating the upper limit of the thickness of a thermoplastic insulating resin on the lead surface at the coating part position turning to a dumb bar. CONSTITUTION:Dumb bars 3 are formed between leads 2 by spreading insulating resin 4 on the leads 2. The insulating resin 4 turning to the dumb bar 3 is spread in lines type on the leads 2 with a dispenser 5. The resin is dried by heating and evaporating solvent with a hot plate 6. The part positions coated with the resin 4 are sandwiched by polymer films 7 easy to be peeled. The resin 4 is heated and pressed from both sides by the plates 6, 8, and made to flow with pressure into the part between the leads 2, 2. The temperature or the pressure is so controlled that the gap M between an upper metal mold and a lower metal mold satisfies the relation M<=T+2(10mum+tF) where T is the lead thickness and tF is the film thickness. Thereby the thickness of the thermal plastic insulating resin on the single surface of the lead at the part position coated with the insulating resin is set lower than or equal to 10mum.
