Title: Controlling method for meandering motion in cross helical rolling work
Inventor: MATSUMOTO HIROMI
IPC: B21B13/14
Filed: 1980-06-11
Abstract: PURPOSE:To eliminate the titled meandering motion with a good responsiveness with a simple, small-sized apparatus, by turning a couple of upper and lower work rolls in the same direction in a plane parallel to the surface of a rolled sheet, while keeping an almost constant crossing angle of upper and lower work rolls during the rolling work. CONSTITUTION:At a stage before starting a rolling work, the axis 10 of an upper work roll is aligned to the axis 15 of an upper backup roll on a vertical plane, and the axis 11 of a lower work roll is aligned to the axis 16 of a lower backup roll on another vertical plane; each pair of work roll and backup roll is opposedly turned by theta/2 in a plane parallel to the surface S of a rolled sheet so as to set a crossing angle theta; after these preparations are finished, the rolling work is started. During the rolling work, if the rolled sheet causes a meandering motion because of a certain cause, only the couple of upper and lower work rolls are turned in the same direction by an angle alpha in a plane parallel to the surface S of the rolled sheet while keeping the initially set crossing angle theta as it is between the upper and lower work rolls;  hereby, the meandering motion of the rolled sheet is eliminated.

Title: Scale adhesion preventing method for terrestrial power generating facility
Inventor: HIROWATARI KAZUO
IPC: F03G4/00
Filed: 1989-03-28
Abstract: PURPOSE:To prevent adhesion of scales by separating H2S from the gas jetted from a terrestrial heat well together with steam and hot water, allowing gas chiefly containing CO2 to be absorbed in the hot water exhausted from a power station, and maintaining the pH at 4-6. CONSTITUTION:Power generation is made through utilization of steam 2 and hot water 3 from a terrestrial heat fluid output by a terrestrial heat well 1, wherein a condensative gas 4 gets rid of H2S at a PSA tower 5 through adsorptive separation, and this H2S adsorbed to an adsorbent is reseparated by decompressing the PSA tower 5 and released through another system 6. Gas chiefly containing CO2 with no H2S included is sent from the outlet 7 of PSA tower to the lower part of an exhaust gas absorbing tower 8, while from its upper part, the untreated hot water 3 exhausted from the power station is supplied in the form of shower, and the hot water after absorption of coal dioxide gas is taken out as treated hot water 11 from the lower part of the exhaust gas absorbing tower 8, where the pH sinks to 4-6. After contact treatment with exhaust gas 10 in a gathering tank 9, this treated hot water 11 is sent to a reductive well 12 or a hot water utilization source 13. Thus scale adhesion can be prevented at a low treatment cost.
