Title: Method for removing sulfur oxide
Inventor: KADOYA MASATO
IPC: B01D53/81
Filed: 1985-11-08
Abstract: PURPOSE:To elevate an adsorbing capacity of the sulfur oxide to the active carbon, and to make the apparatus in a small size by contacting the active carbon impressed the electric voltage with a gas contg. a sulfur oxide, thereby removing the sulfur oxide. CONSTITUTION:The active carbon is filled in a tower, and the electrode provided with an inner wall of the tower and at an inlet and outlet of a gas to be treated and contacted with the active carbon is impressed with an electric voltage, thereby removing the sulfur oxide. The impressed voltage depends upon the concentration of the sulfur oxide contd. in the gas to be treated. However, the amount of the electric current has a less effect on an absorbing capacity. When an excess amount of the electric current is impressed, the generation of joule's heat increases, thereby making an energy loss. Thus, the impressed voltage is preferably 0.5V-10V per 1cm the distance between the electrodes. The impressed voltage may be an alternating current or a direct current, and is preferably the alternating current in the increasement of the absorbing capacity of the active carbon.

Title: Preparing and jetting device for superfine frozen particle
Inventor: FUJINO TAKESHI
IPC: B24C5/00
Filed: 1987-10-02
Abstract: PURPOSE:To obtain the fine frozen particles by installing a means for freezing the vapor evaporated from the frozen liquid under decompression state in comparison with the atmospheric pressure. CONSTITUTION:The frozen liquid 1 in a sealed container 2 is heated by heater 3a, and the vapor generated from the frozen liquid 1 is introduced into a cooling container 4 through a valve 6. In this case, the pressure in a cooling container 4 is in the pressure state lower than the atomospheric pressure by the action of a vacuum pump 9a. Therefore, the frequency in which the vapor particles introduced into the container 4 collide reduces than that in the atmospheric pressure state, and a long period is necessary until the coagulation and growth of the vapor particles. Therefore, freezing is generated before the vapor particles coagulated and the particle diameter increases, and the superfine frozen particles having a fine particle diameter can be prepared. The superfine frozen particles thus prepared are jetted onto the surface of a treated substance (e.g., mask for preparing a semiconductor manufacturing device) 8 through a valve 7, and the surface is blast-treated.

IPC: F28D13/00
Filed: 1983-12-26
Abstract: PURPOSE:To effectively utilize the feature of a fluidized bed to improve the heat conductive performance to obtain a small size heat exchanger of a high performance by setting the specific resistance of solid particles having a conductivity on the surfaces thereof and the surface of a casing to 10<10>OMEGAcm or less. CONSTITUTION:The surfaces of solid particles and the casing have conductivity and the specific resistance thereof is set to 10<10>OMEGAcm or less. Even when the solid particles 10 make collosion with the casing, the attenuation of charge become easy, and they are hardly charged because the solid particles 10 and the casing 11 have conductivity. Accordingly, since no attractive force to attract the solid particles and the casing is produced, all the filled solid particles 10 manifest a stable floating and fluidized state. Hence, around the outer peripheries of the heat exchanger 12 is formed a stable fluidized bed and the gas-liquid boundary layer is broken, thus greatly improving the heat conductivity.
