Inventor: MASE SHINJI
IPC: E04B1/34
Filed: 1987-10-13
Abstract: PURPOSE: To enhance the plastically deforming function and the elastically deforming function of a structural member for an antiseismic building structure in its entirety by setting the section modulus of the structural member along the axis of the latter in accordance with a distribution of bending moments upon exertion of an external force. CONSTITUTION: A building structure A is designed in such a way that an external energy such as that caused by an earthquake is concentrated to a specific layer F in the building structure A, and accordingly, the degree of stress caused by a usual earthquake falls in an allowable stress range while the building structure is allowed to deform up to a degree with which the building structure does not collapses. In this arrangement, the section modulus of a structural member composed of a plasticizing member and an elastic member, along the axis thereof is set in accordance with a distribution of bending moments when an external force is exerted thereto.  With this arrangement, a maximum value of bending moment of the structure member is set to be substantially uniform along the axis thereof, thereby it is possible to effectively exhibit the plastically deforming function and the elastically deforming function of the member in its entirety.

Filed: 1994-10-24
Abstract: PURPOSE: To purify polluted water area efficiently by reducing harmful algae in the polluted water of a closed polluted water system with the growth of harmful algae with the help of a predatory decomposition action by Monas guttula, a micropredator of algae. CONSTITUTION: A polluted water pumped up from a polluted water area 1 with a densely growing water-bloom is poured into a water-bloom-scattering tank 2 and is aerated. Next, the water in the scattering tank 2 is stirred at high speed using a stirring blade 8 to scatter the water-bloom. Then the water is fed to a water-bloom- decomposing tank 3 by a natural flow-down method through a transport pipe 13. In the decomposition tank 3, Monas guttula is inoculated through a Monas guttula inoculation aperture 15 beforehand, so that the water-bloom scattered in the scattering tank 2, is captured and decomposed by Monas guttula. At the lower part of the decomposition tank 3, the carcass of the Monas guttula accumulates as a sediment and becomes sludge, so that this sediment is extracted periodically from a sludge-extraction aperture 18.  The treated water containing a reduced amount of water-bloom is discharged from the top of the decomposition tank 3 through a return pipe 11 and returned to the polluted water area 1.

Filed: 1992-09-28
Abstract: PURPOSE:To lower the reflectance of the surface of a phosphor by coating the surface of the phosphor with a light permeative material having almost the same refractive index as the square root of the refractive index of the phosphor. CONSTITUTION:The surface of a phosphor is coated with a coating material which is a mixture of SiO2 with TiO2 or Al2O3. The refractive index of SiO2 is about 1.4 and the refractive index of TiO2 or Al2O3 is larger than that and the refractive index of the mixture can be adjusted to be near 1.55, which is the square root of the refractive index 2.4 of ZnS, a matrix of a blue- or green- emitting phosphor. The thickness of the light permeative coating material is preferably (1+4+m/2).lambda/n' and the reflactance to the outside light is lowered and no reflection condition that the light emitted from the phosphor inside is not absorbed is produced and thus light scattering is prevented. wherein (m) stands for 0 or position integer, lambda for wavelength of visible light, (n') for refractive index of the coating material. As a result, images with high contrast and black color emphasized are obtained.

IPC: F25B15/00
Filed: 1987-10-14
Abstract: PURPOSE: To rapidly approach the amount of absorption fluid in a producer to a predetermined amount by providing a float valve operable by directly sensing a liquid level on an apparatus for keeping unchanged the amount of the absorption fluid in the producer. CONSTITUTION: Once an intermediate fluid is stored in an intermediate fluid reservoir chamber 25 and an intermediate liquid level is raised, a float 27 is raised, and an arm 29 is rotated, whereby a rotary shaft 30 is turned and hence a first valve element 31 is turned in a closing direction while a second valve element 32 is turned in an opening direction. The flow rate of the thin absorption fluid flowing in from a thin absorption fluid pipe 13 is reduced, and the flow rate of the intermediate fluid that flows out is increased, and hence the amount of the absorption fluid in a high temperature producer 2 is rapidly reduced into a predetermined amount of the absorption fluid.  When an intermediate fluid is reduced below the rotary shaft 30 in the intermediate fluid reservoir chamber 25 and hence an intermediate fluid level is lowered, the float 27 is lowered to rotate the arm 29 and the rotary shaft 30 and hence turn the first valve element 31 in an opening direction and the second valve element 32 in a closing direction. Hereupon, the situation is opposite to the foregoing, and the amount of the absorption fluid in the high temperature producer 2 is rapidly increased to a predetermined amount of the absorption fluid.
