Abstract: PURPOSE:To enable the reduction of energy to be used in an electrodialytic tank and stable long-term continuous operation, in performing the electrodialysis of seawater after purifying the same by multi-stage filtration and heating the purified seawater, by heating seawater subjected to at least one-stage filtration. CONSTITUTION:Pumped-up seawater 00 is separated into purified water and backwashing water 21 in a first stage filter tank 2 and backwashing water 21 is discarded. The temp. of this backwashing water is not raised but backwashing water of the first stage filter tank in a conventional method is already raised in temp. Therefore, heat loss is reduced in this inventive method. In the next step, the purified water 20 is further purified, if necessary, in a multi-stage filter tank and thereafter mixed with low pressure steam 100 in a barometric condenser 1 to obtain warm seawater 10. This seawater 10 is purified in a final stage filter tank 3 to be supplied to an electrodialytic tank 4. Concentrated water 200 is sent to an evaporative crystallizer and desalted water 40 is discarded.

Title: Water treatment method and apparatus
Inventor: KOMATSU NAOTO
IPC: C02F1/44
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To certainly sterilize even a protozoan small in size and hardly detected. SOLUTION: Since the heat treatment of the conc. soln. separated by a membrane treatment device 2 is performed at a time of filtering, for example, when a heating tank 7 is heated to 60 deg.C, even if a protozoan such as cryptosporidium or the like is mixed with the concn. soln., the protozoan can be certainly sterilized. Since heat treatment is performed in a filtering process and the backwashing process of the membrane treatment device 2 even if the protozoan such as cryptosporidium is bonded to the interior of the membrane treatment device 2, the protozoan peeled by backwashing can be certainly sterilized by heating. Therefore, even if the protozoan extremely small in size such as cryptosporidium and hardly detected is contained in raw water, it is prevented that the protozoan such as cryptosporidium again enters a filtering process.

Title: Boiler apparatus
Inventor: AKIYAMA IWAO
IPC: F23C99/00
Filed: 1978-08-16
Abstract: PURPOSE: To check NOx generated in the combustion exhaust gas with a less partial pressure of oxygen in the air by means of an air preheater provided in such a manner as to escape a part of the gas to the side of the combustion air.  
     CONSTITUTION: An incoming air and a fuel sent from a fuel supply conduit line 23 are mixed and burned with a burner 22. After subjected to a heat exchange with water in the boiler 1, the gas enters an air preheater 27 for preheating the combustion air and then, is exhausted. The air preheater adopts a regenerative type while the pressure on the air side of the preheater 27 is lower than on the side of combustion exhaust gas because it is positioned on the suction side of a forced blower 24. This allows a part of the combustion exhaust gas to escape to the air side, sent to the burner 22 with air to control the combustion temperature of the burner. In addition, the gas reduces the partial pressure of oxygen in the combustion air, thereby cheking the generation of Nox.

IPC: G02B6/287
Filed: 1985-05-13
Abstract: PURPOSE:To prevent an optical fiber from being damaged, by constituting the titled device so that a guide curved surface has a large radius of curvature of an extent that the optical fiber which has been bent along its surface does not leak a light, and the tip peripheral surface of a bending tool has a small radius of curvature of an extent that the bent optical fiber can make light incident or can leak it. CONSTITUTION:In a state that a bending tool 19 has been moved backward, an SM optical fiber 11 is stretched between slip clamps 15A, 15B, and clamped. Subsequently, a slide arm 33 is moved forward and the bending tool 19 is pushed in between guides 17A, 17B. The SM optical fiber 11 is slipped in the slip clamps 15A, 15B, and pushed in between the guides 17A, 17B. In this state, when light from a light source 43 is irradiated to a bent part of the SM optical fiber 11, a part of its light is made incident on the SM optical fiber 11 and transmitted in the direction as indicated with an arrow (a). In such a way, the operation is executed very easily, also the bending state is stabilized, and a damage of the optical fiber, especially, a breakage can be prevented.

IPC: G11B7/09
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To predict a resonance frequency of the lens holder in advance after changing specifications of magnetic pieces in the objective lens driving device of a shaft sliding type having a structure equipped with the magnetic pieces for resetting the lens holder into a neutral position and holding this holder therein even when the specifications of the magnetic pieces for adjusting the resonance frequency of the lens holder are changed. SOLUTION: The objective lens driving device 20 for the optical pickup is equipped with one pair of magnetic pieces 10A and 10B for resetting the lens holder 1 into the magnetic neutral position. These magnetic pieces 10A and 10B are constituted to be magnetically saturated with magnetic fields given from magnets 6a respectively. Consequently, even when the magnetic pieces 10 and 10B are changed to adjust the resonance frequency of the lens holder 1, since saturated magnetization of the changed magnetic pieces is known although their magnetic permeability should be different, a resonance frequency of the lens holder 1 after adjustment can thus be predicted.
