Filed: 1989-04-17
Abstract: PURPOSE:To improve working efficiency by providing the plate type filter cloth so as to be allowed to pull out in the direction to cross the movement of the raw water to be filtered. CONSTITUTION:After filter layer is formed, raw water is introduced from a water taking-in pipe G, and captured filthy substances into the filter layer E, and entered into a water collecting chamber B, and only the water treated with filtration is discharged from a discharge pipe H. Then, a water taking-in valve F is closed, and an air supply pipe (d) is connected to a compressed air pump, and an air supply valve I is opened to send compressed air gradually into a tank A. The compressed air fills the inside of the tank A to press the water down, and the water in the tank A is discharged from the tank A. When the water in the tank A is discharged and the water level is lowered under a lower plate (b), the air supply valve I is closed and the filter cloth (a) is taken out. By this method, the secondary pollution due to the washing of filter cloth is prevented.

Title: Method for connecting tube
Inventor: MORIKAWA SHIGERU
IPC: B21D39/04
Filed: 1989-04-19
Abstract: PURPOSE:To carry out everlasting pipe connection having sealing effect at a low cost by using a material softer than a tube connected as a liner and having peripheral teeth on an inner peripheral surface. CONSTITUTION:The drive 1 in which the shape of the tube is stored, is enlarged in diameter at a cold temperature, the liner 2 softer than the tube 3 is inserted into the driver 1 and the tips of the tubes 3, 3 are positioned in the liner 2 nearly in a butting state. Then, when they are heated to a prescribed temperature under this state, the driver 1 is contracted in diameter by the shape recovery force given for the shape memory alloy and the liner 2 compresses the tube 3. At this time, since the liner 2 is softer than the pipe, the peripheral teeth 2a are crushed by the outer peripheral surface of the tube 3, deformed and stuck by pressure and, consequently, sealing properties and resistances to drawing can be secured.

Title: Method of preventing collapse of converter slag and electric furnace slag
Inventor: HARADA GENZABUROU
IPC: C04B5/06
Filed: 1979-07-30
Abstract: PURPOSE: To change the mineral composition of slag and prevent its collapse, by putting a prescribed quantity of clay slate or shale, which is molten at a temperature lower than that of the molten slag of a converter or an electric furnace, into the molten slag.  
     CONSTITUTION: Clay slate or shale, which is molten at a temperature lower than that of the molten slag of a converter or an electric furnace, into the molten slag. The quantity of the clay slate or shale is such that the free CaO and 2CaO.SiO 2  in the steel slag are eliminated. The clay slate or shale reacts with the slag so that the mineral composition of the slag is stabilized. The uncollapsable slag is thus produced without quanching. Since this slag does not collapse or expand, it can be utilized for ballast, sand or the like and the handling of the slag such as transportation is easy.

Title: Fiber gyro
Inventor: EDAHIRO TAKAO
IPC: H01S3/083
Filed: 1982-06-09
Abstract: PURPOSE:To alleviate complexity of the system and to improve measurement accuracy of the rotational speed by a construction wherein optical fibers of a fiber gyro for propagating lights clockwise and counterclockwise are provided separately. CONSTITUTION:Laser beams from a light source 12 branched by a light branching circuit 13 are so adjusted that they have the same characteristic. Since the beam passing through an optical fiber 10 clockwise is propagated in the same direction as a rotational angular speed OMEGA of the optical fiber, the phase of the beam is delayed in a light joining circuit 14 at the exit end by 1/2 of the magnitude DELTAtheta expressed by the equation. Meanwhile, the beam passing through an optical fiber 11 counterclockwise has the phase advanced by 1/2theta, so that the phase difference between both beams becomes DELTAtheta at the exit end 14. Since the beams are propagated through the different optical fibers 10 and 11, the scattered lights therefrom give no influence to each other. This reduces an influence of noises due to scattering. It is thus possible to improve measurement accuracy of the rotational speed with a simple construction.
