    摘要: A field emission element including a gate and an emitter and capable of preventing any of the element oxide layer from being formed on a tip of the emitter to prevent a decrease in emission current, unstable operation and an increase in noise. The gate has a surface formed of a material of oxygen bonding strength higher than that of a material for at least a tip surface of the emitter, so that oxygen atoms and molecules containing oxygen entering the gate may be captured by adsorption on the gate to prevent formation of any oxide layer on the emitter. When a portion of the emitter other than the tip surface is formed of a material of oxygen bonding strength higher than that of the material for the tip surface, formation of any oxide layer on the tip surface of the emitter is minimized.

    摘要: Impurities such as halides and ammonia are efficiently removed from a gas containing Sox at a high concentration without any substantial addition of fresh water in a process for purifying a sulfur oxides-containing gas. The process involves passing a gas containing sulfur oxides and impurities at a high concentration successively through a first washing column and thence through a second washing column, thereby water washing the gas through the two washing columns to remove the impurities from the gas. The first washing column is operated so that the outlet temperature of the gas from the first washing column is at a temperature at which the gas can have a maximum water content or a temperature near this temperature, and the second washing column is operated such that the outlet temperature of the gas from the second washing column at least 20.degree. C. lower than the outlet temperature of the gas from the first washing column.

    摘要: A LED driving apparatus includes a rectifying circuit, first, second and third blocks, and first and second switching portions. The rectifying circuit is connected to AC power supply, and rectifies AC voltage of the AC power supply to provide pulsating current voltage. Each block includes a plurality of LEDs. The first, second and third blocks are serially connected to the output side of the rectifying circuit. The first switching portion switches ON/OFF of a first bypass path based on flowing current amount in the first block. The first bypass path bypasses the second block. The second switching portion switches ON/OFF of a second bypass path based on flowing current amount in the first and second blocks. The second bypass path bypasses the third block.

    摘要: There is disclosed a waste gas treatment apparatus in which dust concentration at a treated gas outlet is sufficiently reduced and the desulfurizing efficiency and denitrating efficiency of grains are increased. The waste gas treatment apparatus includes an inlet member, an outlet member, a moving layer of the grains therebetween, a first perforated plate disposed between the inlet member and the outlet member for defining a front chamber in combination with the inlet member, a second perforated plate disposed between the inlet member and the outlet member for defining an intermediate chamber in combination with the first perforated plate and for defining a rear chamber in combination with the outlet member, and flow controllers for setting the moving speed of grain in the front, intermediate and rear chambers. The moving speed of grains in the front chamber is higher than that in the intermediate chamber and the moving speed of grains in the intermediate chamber is higher than that in the rear chamber.
