Title: Purification method of exhaust gas
Inventor: KANEDA TOYOHIKO
IPC: B01D47/04
Filed: 1979-11-06
Abstract: PURPOSE: To effectively remove the dusts, odors, etc. in exhaust gases by passing the exhaust gases in a foam chamber and allowing the same to contact the foam layer.  
     CONSTITUTION: The foam chamber is constituted by usually using chemical liq. of high surface activity as a foaming agent and filling the formed foam into the chamber. The soot, dust, etc. in exhaust gases are effectively adsorbed mainly by the surface tension of the foam and the odorous materials mainly by the adsorptive force of the foam. For example, in an embodiment 1, a foaming agent spraying device is provided in the lower part of a vessel of a 10t capacity, and an exhaust gas is blasted from the lower part to make a foam chamber. A number of kinds of nonionic surfactants are mixed and are used for the foaming agent. The agent is diluted to 10% with water and is sprayed. The exhaust gas flow is 500m 3 /min and contains cigarette dust. As a result, no cigarrette dust is observed in the exhaust gas past the chamber and the effect by the foam chamber was confirmed.

Title: Electromagnetic ultrasonic flaw detection method and apparatus
Inventor: MURAYAMA RIICHI
IPC: G01N29/04
Filed: 1984-07-10
Abstract: PURPOSE:To make it possible to detect the flaw formed to a material to be inspected regardless of the extending direction thereof, by generating electromagnetic ultrasonic waves from a plurality of coils respectively different in the direction of line f magnetic force. CONSTITUTION:When pulse burst currents having different current supply periods and an equal cycle are supplied to coils 1, 2, 3, which is arranged so that the directions of lines of magnetic force passing through the coils are different, in such a state that a steel pipe P being a material to be inspected received DC magnetization, the surface magnetic flux of the steel pipe P changes and eddy currents are generated to the surfaces of the steel pipe P opposed to the coils 1, 2, 3 with the change in aid magnetic flux. An electromagnetic ultrasonic wave is generated by said eddy currents and DC magnetic fields and the propagation direction thereof is brought to the axial length direction of each coil. Said ultrasonic wave is propaged through the surface layer part of the steel pipe P as a surface wave having a wavelength equal to the interval of the coils and, if there is a flaw in the surface layer part of the steel pipe P, the surface wave is reflected by the flaw to generate an eddy current. The induction voltages of the coils 1, 2, 3 due to this eddy current are detected to judge the presence or absence of the flaw of the steel pipe P.

Filed: 1986-06-23
Abstract: PURPOSE:To maintain glow discharge required for laser oscillation stably by making the flow velocity of a gas laser medium at both end sections as the optical resonator side of a discharge electrode larger than a central section in a drift type gas laser oscillator.
