IPC: B01D39/20
Filed: 1991-04-17
Abstract: PURPOSE:To prevent a filter from becoming clogged by adding a coagulant to an untreated liquid to coagulate particles in the untreated liquid and filtering the supernatant liquid using a cyclone and a ceramic filter after enlarging the diameter of the particle and precipitating it. CONSTITUTION:First, an untreated liquid such as waste water after polishing process is allowed to flow into an untreated liquid tank 1 through a flow path 11, and then is transported to a reaction tank 3 passing through a flow path using a liquid feed pump 13. In addition, a coagulant is sent from a chemical tank 2 where it is stored using a liquid feed pump 15 with the concurrent stirring of the coagulant using a stirring device with bubbling air, and is added to the untreated liquid. Further, the untreated liquid and the coagulant are stirred by a stirring device 17 in the reaction tank 3, if necessary, so that their adequate reaction takes place, and the untreated liquid is transported from the reaction tank 3 to a precipitation tank 4. After precipitation of the particles in the untreated liquid and subsequent separation of slurry and a supernatant liquid from the untreated liquid, the supernatant liquid is filtered using a cyclone 5 and a ceramic filter 6. In this case, the supernatant liquid is sent to the ceramic filter 6 through a flow path 21 and then is sent to the cyclone 5 passing through a flow path 24.

Title: Semiconductor circuit
Inventor: TAKAISHI TORU
IPC: H03K5/02
Filed: 1994-07-28
Abstract: PURPOSE:To prolong the time required to rise and fall the output waveform and to prevent t malfunction due to the change of the waveform of an output voltage signal by changing a control voltage waveform which drives the transistor in an output means by the time function. CONSTITUTION:The control voltage waveform in a control voltage waveform control means 10 is changed by the time function. For example, the time change rate of a control voltage waveform N2 is changed according to the time change in response to the change of the signal inputted to an input means 2. That is, the internal control output voltage waveform to be outputted from the output circuit is suppressed during the time when the output waveform to be outputted from the output transistor being the output means is changed. The internal control output voltage waveform is changed rapidly in the other time. Thus, the deterioration of the operation speed can be reduced as much as possible and the fluctuation due to the noise or by reflection on the output signal can be suppressed as much as possible.

Title: Manufacture of bi series oxide superconductor fabricated by fusion method
Inventor: KUME ATSUSHI
IPC: C30B29/22
Filed: 1991-06-21
Abstract: PURPOSE:To enhance the crystal orientation and heighten the critical temperature and critical current density by forming over a metal base an oxide film and a buffer layer for accomplishing a composite base, and thereover forming an oxide type superconductive layer. CONSTITUTION:An oxide film 7 is formed on the over-surface of a metal base 6, and thereover a buffer layer 8 is formed, and further thereover a crude material powder layer is formed which contains elements constituting a Bi type oxide superconductor. The resultant is heated in a furnace to turn the crude material powder layer into a fusion/solidification layer. Part of this layer is irradiated with a laser beam so as to generate a locally molten band, which is moved in the longitudinal direction of the base, and the whole fusion/solidification layer is left to unidirectional solidification bit by bit so as to produce an oxide superconductive layer. This suppresses diffusion of composite base 9 constituent elements to the oxide superconductive layer side, and also lessens dispersion of the thickness compared with the case where the crude material powder is directly subjected to unidirectional solidification. This allows enhancing the workmanship of the crystal orientation of the oxide superconductive layer and also heightening the critical temp. and critical current density.

Title: Shaking type mixer
Inventor: SUZUKI HISAAKI
IPC: B01F11/00
Filed: 1984-08-28
Abstract: PURPOSE:To remove air bubbles adhered to the periphery of a material or air involved in internal gaps, by arranging a rotary drive apparatus, which applies mixing motion different from the shaking motion of a bottom part to a material during mixing, to a shaking mixer. CONSTITUTION:After predetermined weighed materials such as cement, a fine aggregate or water were thrown in a mixing container C, an upper lid 26 is closed by bolts 30 to hermetically close said container C. When a hydraulic motor 12 is subsequently rotated, a shaking plate 16 generates shaking motion thrugh a shaking part B and the materials in the mixing container C are diffused and mixed. Succeedingly, when a vacuum pump V is operated to evacuate the mixing container C and, at the same time, the sucking is performed from the suction socket 33 in the side of a reversal frame, vacuum advances outside and inside the mixing container C. Because air between aggregates is sucked in the mixing container C, even if fluffy carbon fibers are present, the materials are equally dispersed without generating small lumps or pillings.

Title: Treatment of cooling water and water treatment agent
Inventor: SARUWATARI YUJI
IPC: C02F1/50
Filed: 1989-07-12
Abstract: PURPOSE:To prevent that circulating cooling water becomes alkaline and to perform high concn. operation by adding a hydrazine salt to the circulating cooling water. CONSTITUTION:Circulating cooling water to which a hydrazine salt is added is alkaline at first but becomes acidic gradually. Even when the concn. of salts is generated by circulation use, the acid discharged by the decomposition and disappearance of hydrazine acts so as to prevent the system from becoming alkaline. Therefore, operation can be performed without raising the pH of cooling water and, as a result, high concn. operation becomes possible without fearing environmental pollution due to blow drainage and water can be conserved highly and economical efficiency is also achieved.

Abstract: PURPOSE:To prevent one generation or an additive axial tension by a method wherein a resilient plastic damper arranged between structures forms a rotary body in the shape of a filled-spandrel in cross section, the one end of two ends being a mounting part is fixed to the structure and the other end is inserted in the insertion hole of the structure, and an intermediate part is formed in a vertical shape responding to bending moment distribution. CONSTITUTION:A resilient plastic damper A is arranged between structural members 1 and 1 and formed in the shape of a rotary body in the shape of a filled-spandrel in cross section so that it is deformed during relative movement in the arbitrary directions of the two structural members to absorb structure vibration energy. The damper A comprises mounting parts 2 at two ends and a damper part 3 being an intermediate part, and the damper part 3 is formed in a vertical shape responding to bending moment generated during exerting of an external force and forming a curve producing a dynamical unit stress in an axial direction. Meanwhile, the mounting part 2 is fixed to the structural member 1 comprising a head part 4 and a thread part 5. The other mounting part 2 is formed in a circular shape and inserted in an insertion hole 6 formed in the structure 1 and moved in an axial direction. Thus, since, no axial tension is generated at the damper A, during execution of a work, mounting of the damper A can be carried out at any time.
