IPC: C02F1/44
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To rapidly supply clean water by decreasing the frequency of cleaning of a hollow fiber membrane filter and continuing supplying of clean water for a long time. SOLUTION: In a clarification apparatus for clean water wherein the clean water is formed by filtering raw water supplied by driving a pump 1 by means of a hollow fiber membrane filter 4 and a cleaning means for cleaning the hollow fiber membrane filter 4 is installed, and bleed-off circuit 20 provided with a circulation path 18 for circulating a part of the raw water sucked by means of a pump 1 from the ejection side of the pump 1 to the suction side and a flow rate control valve 19 for controlling the flow rate of the raw water flowing this circulation path 18 is installed.  When filtering performance of the hollow fiber membrane filter 4 is decreased as impurities in the raw water are stuck on the surface of the hollow fiber membrane, pressure of the raw water supplied to the hollow fiber membrane filter 4 side is elevated by downing the divergence of the flow rate control valve 19 and the amt. of supplying is increased to recover the amt. of formation of clean water and to decrease the frequency of cleaning of the hollow fiber membrane filter 4.

Title: Array antenna unit
Inventor: KUGOU KOUJI
IPC: H01Q21/06
Filed: 1979-01-16
Abstract: PURPOSE:To make it possible to set radiated-wave surfaces in phase even if an in- use frequency would be varied, by forming array surfaces of an antenna element group in a curved-surface shape so that distances from a radiation beam focus to respective antenna elements will be equal. CONSTITUTION:Array surfaces of an antenna element group are formed in a curved-surface shape so that distances from a radiation beam focus to respective elements A1-An will be equal, and waves are radiated in phase from elements A1-An. For the purpose, output terminals of power distributors 11 are connected to elements A1-An via feeders 211-21n equal in length. As a result, paths from distributor 11 to focus F by way of respective feeders and antenna elements are equal in length and radiated waves are in phase at focus F. Consequently, even if an in-use frequency would be varied, radiated waves of respective antenna elements A1-An can be held in phase and a maximum radiation electric field can be ob- tained at focus F.

Filed: 1986-01-13
Abstract: PURPOSE:To raise the efficiency of dredging by enhancing the concentrating degree of sludge in the sludge hold by providing a pump for sucking up overflow water from the sludge hold and a transport pipe for the overflow water. CONSTITUTION:Mud water being dredged is sent from a drag head 3 to a drag arm 2, a dredging pump 4, a mud water discharge pipe 5, a trough 6, and a sludge hold 7 where sludge 9 is settled. Muddy water 10 separated from the sludge 9 is overflowed from a gate 11 for overflow water and sent to a duct 12 for overflow water, a pump 13 to deliver overflow water, and a pipe 14 to deliver overflow water. The muddy water is then sent to the head 3, the arm 2, the pump 4, the pipe 5, the trough 6, and the hold 7 in a circulating manner. Since the needs to discontinue dredging operations before mud water overlows can be eliminated, the efficiency of dredging can be enhanced.

Autoclave curing in a first process is set to 1 to 3 atm G, and heat at the time of this curing is lowered as much as possible to prevent the heat deterioration of the synthetic resin fiber and to enhance the bonding strength of a cement matrix. A water curing period in a second process is set to 15 days or longer to promote the hardening reaction of cement. Drying in a third process is carried out for removing surplus water contained in the cement plate by the water curing, and a drying temperature is limited to 80 to 110 deg.C to reduce a water content in the cement plate to 2% or less.

Title: Production of oxide glass thin film and apparatus therefor
Inventor: SAITO MASAHIDE
IPC: G02B1/12
Filed: 1992-01-13
Abstract: PURPOSE:To obtain the subject method in which an oxide glass thin film of a desired thickness can be produced and apparatus therefor. CONSTITUTION:A fuel and a raw material gas are fed to a torch 13 to deposit glass fine particles on the surfaces of substrates 11 on a rotating turntable 12. In this case, the substrate (11a) is irradiated with inspecting light from a light source 23 and the extinction transmitted through the substrate (11a) is measured based on the output from a detector 25 and a measuring instrument 26. Thereby, the thickness of the glass fine particulate layer formed on the substrate (11a) can accurately be measured. That is, the extent of scattering increasing with the growth of the glass fine particulate layer is proportional to the film thickness of the glass fine particulate layer. As a result, the extinction detected with the detector 25 can be monitored to accurately determine the thickness of the formed glass fine particulate layer. Accordingly, the oxide glass fine particulate layers deposited on the respective quartz substrates 11 can be regulated to a constant thickness.

Title: Aluminum pipe having grooved inner surface and production thereof
Inventor: TONOKI TATSUYA
IPC: F28F1/40
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To obtain an aluminum pipe having a large number of grooves in the inner surface being used as the heating tube of a heat exchanger in which exposure of new aluminum surface is eliminated when the pipe is enlarged by providing an oxide coating layer of specified thickness on the inner surface of the pipe. SOLUTION: An aluminum pipe 1 has a large number of grooves 2 in the inner surface applied with an oxide coating layer 3 of 5 μm thick or above. Al material of the aluminum pipe 1 having grooved inner surface is not limited and includes industrial pure Al, Al alloy, and the like. Even if a mandrel is pushed into the pipe in order to enlarge the pipe when the pipe is set in a heat exchanger, the oxide coating layer 3 is not cracked easily and the new aluminum surface is not exposed substantially on the inner surface of the pipe. Since seizure does not take place between the inner surface of the pipe and the mandrel when the pipe is enlarged, the groove 2 in the inner surface of the pipe is not collapsed and the mandrel can be pushed in well.

Title: Radial loader for measuring vibration/sound of rolling bearing
Inventor: OTA HIROYUKI
IPC: G01M13/04
Filed: 1993-01-13
Abstract: PURPOSE:To eliminate adverse effect of the rigidity of a loader on the natural frequency of a rolling bearing and to prevent the loader from causing temporal fluctuation in the measurement of vibration/sound. CONSTITUTION:The radial loader for measuring vibration/ sound of a rolling bearing imposes radial load to a rolling bearing 1 fixed to a rotary shaft 2 when vibration/sound of the inner ring 1a thereof is measured during rotation thereof. A lever 7 has an arm 7a fixed, at one end thereof, with a weight 6 and a low rigidity elastic (rubber) finger (protrusion) 9 at the other end thereof wherein the finger 9 presses, at the tip thereof, the outer ring 1b of the bearing 1 vertically thus imposing radial load thereto. Since a rubber finger 9 having low rigidity is employed, rigidity of the loader has substantially no effect on the natural frequency of the bearing 1. Furthermore, since load is applied to the lever 7, the outer ring 1b is restricted stably and temporal fluctuation in the measurement of vibration/sound due to the loader is substantially eliminated.

Title: Operation method of reactor
Inventor: SUEMATSU SHIGERU
IPC: G21C7/00
Filed: 1978-01-20
Abstract: PURPOSE: To prevent stress corrosion cracking by forming an inert gas layer in a reactor vessel at the stoppage and reducing the concentration of dissolved oxygen as well as dissolved hydroperoxide before the raising of the output.  
     CONSTITUTION: After the fuel change is ended with the stoppage of the operation, the top of a reactor vessel 2 is sealed up. A nitrogen gas is fed into the reactor vessel 2 from a feeder 11 to form a nitrogen gas layer. The nitrogen gas layer thus formed checks the dissolving of oxygen in the air and the resulting partial pressure permits reduction in the concentration of dissolved oxygen. The concentration of dissoved hydroperoxide intensifies in the rate of reduction when the temperature of cooling water exceeds 150°C in the reactor vessel. Then, as the control rod is withdrawn gradually from the core, nuclear heating is started.
