Abstract: A method of brazing a honeycomb for air sealing onto a braze surface of the front end of the stationary blade of an axial-flow compressor in accordance with the invention includes the steps of: placing a filler sheet between the honeycomb and the braze surface; constraining the honeycomb in the seal width direction so that the seal width direction of the honeycomb corresponds to the seal width direction of the braze surface while keeping the figure of the honeycomb at the same curvature with that of the braze surface; and heating the assembly to braze the honeycomb and the braze surface.

Abstract: A method for collecting volatile organic substances from an off-gas containing moisture and volatile organic substances. The organic substances are removed from the gas containing the organic substances and the moisture by introducing the gas into an adsorbing tower filled with the adsorbents and being in the adsorbing process under a relatively low temperature condition. The gas is discharged outside the system as the gas containing the moisture but from which the organic substances have been removed. The organic substances are desorbed under a relatively high temperature condition in the regenerating process for the regeneration. The moisture is removed from the desorbed gas discharged from the adsorbent regenerating process in a dehumidifying tower filled with the moisture absorbent by the temperature swing method or pressure swing method.

Abstract: A method for collecting volatile organic substances from off-gas containing moisture and volatile organic substances. After the moisture has been removed by a dehumidifying tower filled with moisture absorbent for selectively adsorbing the moisture from the gas containing the organic substances and the moisture, the organic substances are adsorbed and removed under a relatively low temperature condition. The organic substances is desorbed under a relatively high temperature condition from the adsorbing tower which is saturated with the organic substances. The desorbed organic substances are liquefied and collected under a low temperature and/or pressurizing condition. The dry gas from which the organic substances have been removed and made harmless is heated if necessary.

Abstract: In a method of desulfurization used at a geothermal power plant, stem removed from a production well, after being used for power generation, is condensed and separated into condensed water and hydrogen sulfide-containing gas, and the hydrogen sulfide-containing gas is treated at biochemical treatment tank. The initial cell density of the reactor liquid of the biochemical treatment tanks is adjusted by cell culture liquid obtained from a cell breeding culture tank provided independently of the biochemical treatment tanks and water or a part of hot water returning to a reduction well, hydrogen sulfide-containing gas is supplied thereinto and desulfurized thereat. With lowering of activation at the biochemical treatment tanks and with lowering of desulfurization ability there, the acidified reaction liquid is removed and is added to the hot water returning to the reduction well. Accordingly, addition of inorganic nutritive salt for cell breeding becomes unnecessary.

Abstract: In the present invention, when a tire is vulcanized, a flange fixed to either one of a top plate of a split mold and a piston rod tip end of a split mold opening/closing cylinder is held by operating fingers. The fingers are assembled in such a manner to be capable of oscillating in the holding direction by the return force of a spring. The top plate is connected to a piston rod of the split mold opening/closing cylinder. Thereupon, the split mold is opened and closed by the output of the split mold opening/closing cylinder and the vertical movement of a bolster plate. When the split mold is replaced, holding is released by oscillating the fingers by using a finger driving device, by which the top plate is separated from the piston rod of the split mold opening/closing cylinder.

Abstract: A flexographic printer in which ink supplied into a nip portion of inking rolls. The inking rolls include a rubber roll and an anilox roll. An inking roll cover is provided around the inking rolls. Clean air is directed into the inking roll cover through a filter, such as by a fan which blows air through an air vent into the inking roll cover so as to form a slightly higher static pressure within the inking roll cover than in the peripheral area. As a result, air is ejected to the outside of the inking roll cover from a gap between the inking roll cover and the printing cylinder. A dynamic pressure caused by the air prevents paper dust, paper scraps or other scattering dust, etc., from coming within the inking roll cover, thereby preventing such from sticking on the outer circumferential face of the rubber roll or the anilox roll, or from mixing with the ink supplied into the nip portion of the rubber roll and the anilox roll.
