Filed: 1984-04-28
Abstract: PURPOSE:To perfectly remove air pollution substances such as CO, NOx, hydrocarbon or SOx motor car exhaust gas, by attaching a water treatment chamber in a sound arresting muffler. CONSTITUTION:The exhaust gas of an engine goes over a water seal plate 7 from the exhaust gas port of a filter and scattered into the water in the treatment chamber 4 of a first water tank from holes of the drainboard 12 fixed above the water surface 48 in order to stop the shaking of the water surface 48 through an undereater scattering trough 15. After air pollution substances are dissolved in water, the exhaust gas is guided to a limestone filter chamber 25 from the opening part 9 of a partition plate 18 for partitioning the chamber and the air pollution substances are decomposed by the alkalinity of limestone. Subsequently, the exhaust gas is guided to a charcoal filter chamber 29 from the holes of a limestone pressing drainboard 28 to remove an offensive smell and air pollution substances. The treated exhaust gas is passed through water to be guided to a stainless steel fiber filter 39 through a limestone filter 37 to remove suspended substances therein and guided to a charcoal filter chambe 41. Similar treatment is repeated to raise and fall the exhaust gas which is then exhausted from an exhaust port 84 through fiber filters 68, 73, 78.

Title: Bubble deaeration equipment of printed board
Inventor: NAKAGAWA YOSHIZO
IPC: H05K3/26
Filed: 1990-04-03
Abstract: PURPOSE:To effect a rapid and good deaeration over the whole plane of a printed board by a method wherein the liquid flow, which is produced by a jetting of a liquid from a jetting outlet of a nozzle or a suction of the liquid through a suction inlet of the nozzle, passes through a through-hole of the printed board and washes away the bubbles staying in the through-hole. CONSTITUTION:When a pump 33 is actuated, a liquid spouted from the pump 33 flows through a pipe and an flexible hose into a nozzle 24. Then, it is jetted from a jetting outlet 26. Also, the liquid flows into a nozzle 25 through a suction inlet 27 and is sucked up by the pump 33. The liquid passes through a through- hole of a printed board 9 with a strong force and the liquid flow deaerates the bubbles staying in the through-hole rapidly and well. Meanwhile, when an electric machine 6 is actuated, sliders 20a and 20b go up and down unitedly with the nozzles 24 and 25 and a deaeration effected by the liquid flow ranges over the whole plane of the printed board 9. The sliders 20a and 20b are moved up and down a few times. At this time, brushes 30a and 30b attached to a covering body 29 moves up and down unitedly with the nozzle 25 and its front end enters into the through-hole of the printed board 9, thereby deaerating small bubbles well.

Abstract: PURPOSE:To obtain the titled magnet showing high magnetic properties, by subjecting the secondary billet of Mn-Al-C magnetic alloy which is allowed to exist in the primary hollow billet to compression working in an axial direction until both billets come into contact with each other so that compressive strain in the outside peripheral part is lower than that in the inside peripheral part. CONSTITUTION:The secondary hollow billet 2 composed of Mn-Al-C magnetic alloy and the tertiary billet 3 composed of metallic material are allowed to exist in the inside of the primary hollow billet 1 composed of metallic material. Then the billets 1-3 are subjected to compression working by pressurizing the billets 1-3 in an axial direction by the user of punches 4 and 5 whose surfaces to be brought into contact with the billets have inclined planes, respectively, as illustrated in figures. As a result, compression working is carried out so that compressive strain of the billet 1 is lower in the outside peripheral part than in the inside peripheral part and, moreover, the billets 1-3 are brought into contact with each other. In this way, the Mn-Al-C alloy magnet increased in diameter-direction magnetic properties as compared with one obtained by known method when compared based on the same amount of compressive strain.
