Abstract: The method of the present invention is capable of securely removing air from a space between the cover glass and a slide glass and securely locating a damaged part of a specimen outside of a visual field of a microscope. One end of the cover glass is held by a sucking pad, which is provided to an arm capable of rotating and vertically moving. Then, cover glass is obliquely held in a state. The one end of the cover glass is located on the upper side with respect to the other end thereof. A position of a rotational axis of the arm is moved to a position under the slide glass, and the arm is rotaed to make the other end of the cover glass contact the slide glass and curve the cover glass, and the one end of the cover glass is gradually moved toward the slide glass.

One end of the cover glass is held by a sucking pad, which is provided to an arm capable of rotating and vertically moving. The cover glass is obliquely held with respect to the slide glass. The one end of the cover glass is held higher than the other end of the cover glass. A position of a rotational axis of the arm is moved to a position under the slide glass.

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.
