Title: Pressure-swing-type adsorption apparatus for carbon dioxide recovery from nitrogen oxide-containing raw material gas
Inventor: SHIBAMURA KENTARO
IPC: C01B32/50
Filed: 1990-07-26
Abstract: PURPOSE:To separate and recover carbon dioxide from nitrogen oxide-containing raw material gas at high yield constantly by filling an adsorption column with an adsorbent in an excessive amount corresponding to the saturated accumulation amount of the nitrogen oxide, which is contained in the raw material gas, to accumulate on the adsorbent. CONSTITUTION:Carbon dioxide is separated and recovered from a raw material gas containing nitrogen and carbon dioxide and as an impurity nitrogen oxide by allowing carbon dioxide to adsorb on an adsorbent (e.g. activated carbon) with which adsorption columns 13, 14 are filled. At that time, the adsorption columns 13, 14 are filled with the adsorbent in an excessive amount corresponding to the saturated accumulation amount of the nitrogen oxide contained in the raw material to accumulate on the adsorbent. In other words, using a slightly large amount of the adsorbent as compared with the case that the adsorbent of activated carbon is used under the condition of being degrading by the nitrogen oxide accumulation on the adsorbent, not only carbon dioxide as a production gas is recovered at high efficiency constantly but the equipment for removing nitrogen oxide is made small or omitted and thus production cost can be lowered.

When the hydraulic oil flows in a small flow rate only in the hydraulic circuit part equipped with the first throttling part, operation speed of the actuator becomes low. The hydraulic oil continues flowing in the hydraulic circuit part equipped with the first throttling part during opening and closing operation of the hydraulic circuit part equipped with the second throttling part.

Filed: 1985-09-09
Abstract: PURPOSE:To exclude the positional detection error of a sensor board due to arrangement shift and to eliminate a neutral point where a transmitted light receiving element comes to a non-operative state, by arranging a reflected light receiving element and the transmitted light receiving element. CONSTITUTION:A light emitting element 4 lights to irradiate a sensor board 5. Whereupon, a reflective plate 5a reflects the light of the element 4 and a reflected light receiving element 6 is irradiated with the reflected light to be operated. When the board 5 revolves, the positions of the reflective plate 5a and a slit part 5b move. When the reflective plate 5a moves, the incident angle and the angle of reflection of the light from the element change and, on the basis of this change, a large number of elements 6 arranged in a row can detect the movement and the angle of rotation of the board 5. When the board 5 rotates and the slit part 5b is positioned on the straight line connecting the element 4 and a transmitted light receiving element 7, the light from the element 4 passes through the slit part 5b to irradiate the element 7. The element 7 is irradiated with the light from the element 4 to be operated and detect the movement and the number of rotations of the board 5. By arranging the elements 6, 7, the error due to the arrangement shift of the board 5 can be excluded.

Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To uniformize the shape of a weld nugget by comprising the positive half cycle with the two sets of the first and the second waveforms, which rise from the zero point to the peak and then lower to the zero point, and raising the voltage at the peak higher in the second waveform than in the first. SOLUTION: The first waveform rises from the zero point to the first peak point g, and then lowers to the zero point. The second waveform rises from the zero point to the second peak point h, and then lowers to the zero point. A positive half cycle is comprised of the first and the second waveforms. A voltage value is made larger at the first peak point g than at the second peak point h. Similarly, a negative half cycle is comprised of the third and the fourth waveforms. Using the AC waveform 40 as a reference current wave, the voltage of the secondary side of a welding transformer turns to a waveform 41, so that no undershoot is generated for the current waveform 42 at point k. The current values are equalized at the first and the second peak points. Welding speed can be raised without excessively heating a weld zone.
