Patent JP-S5660622-A (JP)
Title: Air cleaning equipment
Inventor: URAGAMI HIDEAKI
IPC: B01D47/02
Filed: 1979-10-22
Abstract: PURPOSE: To simplify the structure of equipment and to efficiently remove dust particles from a dirty air by a method wherein a dust-containing air is passed through a dust-removing pass dipped in a liquid so that particles such as dust are separated from the air and gathered in the liquid.  
     CONSTITUTION: The liquid tank 2 is filled with a surfactant-containing liquid and the suction unit 10 is driven so as to reduce the pressure in the air discharge chamber 5. The suction force due to the suction unit 10 acts on the inlet of the dust- removing pass 13 and causes the dust-containing air to be flowed into the air take- in chamber 4. At the time that the air goes from the expanded section 16 to the contracted section 17, it collides with the inside wall surface of the plates 14, 15 and  separates particles such as dust from the air flow and dropped into the liquid in the  pass 13. At this time, pressure change occurs and the pressure increase in the  expanded section 16 causes the liquid to bubble, and the dust particles are adsorbed  by the surface of bubbles. While the bubbles move through the pass 13, the particles gather together and are settled to the bottom of the liquid tank 2 at the outlet  of the pass 13.

Title: Proportion counter for neutron moisture meter
Inventor: SASE YOSHIHIRO
IPC: H01J47/06
Filed: 1977-11-16
Abstract: PURPOSE: To reduce the noises coming from the gamma ray by extending a thin silver plate on a portion of a cathode, which is positioned in the vicinity of a neutron source of an  3 He proportion counter, so as to absorb the gamma ray which is emitted from the neutron source to enter a  3 He neutron proportin counter.  
     CONSTITUTION: An  3 He proportion counter 1 is composed of a cathode 2, an anode 3, an insulating member 4 supporting the anode 3, and a connector 5. With respect to the  3 He proportion counter 1, a neutron source 6 is constructed to be positioned at the center of the effective length 7 of the counter 1. A silver plate 8 is wound on the cathode 2 such that it covers the effective length 7 with respect to the neutron source 6. As a result, the gamma ray, which is emitted from the neutron source 6 to enter the counter 1 thereby to generate noises, can be absorbed by the silver plate 8 thereby to reduce the noises of the counter 1.
