Title: Narrow-band superposition modulation signal generator
Inventor: BOKU JITSUKON
IPC: H03H17/02
Filed: 1991-09-30
Abstract: PURPOSE: Not only to enable use as a filtering means for a band limit but also to adjust the band width of a main lobe and rediffusion degree of a side lobe by providing 1st-3rd filtering means, attenuating means and adding/subtracting means. CONSTITUTION: A 3rd filter 6 is a low filter for which a power 3dB cutoff frequency fc is less than 1/T (T is symbol cycle), and an output S(t) is generated through signal conversion, so that the main lobe and side lobe can be narrow bands by limiting the frequency spectrum of an output signal S3 from a subtracter 3. The filter 6 is used as a filter, having a transmission function of Butterworth form an the power 3dB cutoff frequency fc and a pole number N or a base-band power spectrum change on a linear channel due to the value of superimpose degree A, can be provided. Since power spectrum and error probability performance is changed corresponding to that change, a parameter is determined, while being mutually complemented so as to satisfy the request conditions for main lobe and side lobe of this system.

Inventor: SHIMIZU HIROSHI
IPC: C02F1/44
Filed: 1988-10-06
Abstract: PURPOSE:To give a reducing agent in the minimum necessary amount constantly by computing the necessary amount based on flow rate of water to be treated and the dissolved oxygen concn., measuring the dissolved oxygen concn. after a reducing agent addition., and adding the reducing agent in a specified necessary amount when the measured amount is either more or less than a predetermined value. CONSTITUTION:When sea water 1 is made fresh water 4 through a reverse osmosis membrane 3, a reducing agent 5 is added to the sea water 1 in a pipeline 2 so as to remove oxygen dissolved in the sea water. To do it, the flow amount of the sea water 1 and dissolved oxygen concentration (SO) are detected and the sufficient amount of the reducing agent 5 to meet prescribed volume to the permissible (SO) is computed. Then, the open degree of a valve 7 to meet the prescribed injection amount is automatically set and the reducing agent is injected. When (SO) in the sea water 1 suddenly becomes more than the permissible value, (SO) after addition of the reducing agent 5 is detected by a (SO) detecting terminal 11. If the detected (SO) is higher than a short-term permissible value, the injection amount of the reducing agent 5 is corrected and increased, and when (SO) becomes less than the short-term permissible value, the correction is stopped and the amount is returned to the original amount.

Filed: 1986-10-24
Abstract: PURPOSE:To remove stuck scales by leading hot water to a magnetic field and returning this hot water to a reduction well and thereafter intermittently injecting high-temp. hot water into the reduction well. CONSTITUTION:A steam turbine is driven by steam discharged from a separator 14 and also driven by steam obtained from high-temp. and high-pressure hot water. Low-temp. hot water is returned to a reduction well 36 via a pipe 40 and silica scales are stuck to the inside of the reduction well 36 because the low-temp. hot water fed to the well 36 is passed through a magnetic field. Then high-temp. and high-pressure hot water is injected into the well 36 via a pipe 34. Thereby stuck silica scales are separated and also the scales incorporated in the well 36 can be dissolved and removed. Thereby the service life of the reduction well can be prolonged.
