Title: Sheet-like phosphorus removing material and phosphorus removing method
Inventor: KATAOKA KATSUYUKI
IPC: C02F1/58
Filed: 1993-01-27
Abstract: PURPOSE:To remove phosphorus in a close water area extremely simply and effectively and prevent or solve eutrophic condition by preparing a sheet-like phosphorus removing material by carrying a substance having a phosphorus adsorbing function on a sheet-like material and simply hanging the sheet-like phosphorus removing material in the water. CONSTITUTION:A sheet-like phosphorus removing material 1 is prepared by carrying a substance having phosphorus adsorbing function on a sheet-like material. The sheet-like phosphorus removing material 1 is hung under surface level 4 of water of such as lakes and marshes, dams, rivers, etc., containing phosphorus by a float 3. A sinker 2 is attached to the lower end of the sheet-like phosphorus removing material 1 and the sheet-like phosphorus removing material 1 is set in a slightly tensile condition. In this way, phosphoric acid ion can be adsorbed and removed effectively only by immersing the sheet-like phosphorus removing material 1 under the object water from which phosphorus should be removed. Due to high phosphorus adsorbing capacity, for example, aluminum hydroxide powder applied to the sheet surface can be used for a long duration.

IPC: C02F1/00
Filed: 1993-02-19
Abstract: PURPOSE:To prevent preferential growth conditions for red tide from being created and prevent thereby the red tide from generating by moving an air ejector with jet holes arranged over an extensive area in the about 10m depth of water, ejecting air from the holes. CONSTITUTION:If an air ejector 3 is towed by a mother ship 1 in the about 10m depth of water and at the same time, air is ejected from ejection holes 8 provided on the main wing 5 of the air ejector 3, the ejected air (a) stirs a nutrious salt formation layer A in the form of a foam soaring current. Consequently, the water depth H1 of the nutritive salt formation layer A located in the depth of 7 to 8m is shifted to a depth H2 of about 10m. In some case, as the layer A disappears and thus one of the red tide creative conditions is no longer present, it is possible to prevent the red tide from generating. The jet holes 8 provided in the air ejector 3 eject air to stir a broad area efficiently, so that the more extensively the jet holes 8 are arranged, the better.

Abstract: PURPOSE:To obtain a titled optical fiber which is excellent in its moisture resistance and has a long life and a small transmission loss, and also to constitute it so that the transmission loss does not increase even if an external force is applied, by coating successively a metallic coated layer, a thermosetting resin layer and a buffering resin layer onto the outside circumferential surface of an optical fiber bare wire. CONSTITUTION:An optical fiber bare wire 1 is protected by a metallic coated layer 2, moisture does not work on a minute surface defect of the bare wire 1, and it is excellent in its moisture resistance. The metallic coated layer 2 is formed thinly, and its transmission loss does not become large as a usual metallic coated optical fiber.

Title: Ic card
Inventor: OBUCHI ATSUSHI
IPC: B42D15/10
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent rise of temperature in an IC card and block short circuit and corrosion of an electric circuit due to dew condensation by coating or filling a part or the whole part of a space in the IC card wherein an electric circuit module is being pinched by a base and a cover with a highly absorbent polymer. SOLUTION: A highly absorbent polymer 10 has a function as a drying agent in an IC card and a function as a seal material of an electrode of a capacitor 9 so as to wrap one electrode of the capacitor 9. Even when dew is condensed, moisture is absorbed and held by the absorbency of the highly absorbent polymer 10 so as to prevent a short circuit between the electrodes to be generated by migration of an electrode material. As the highly absorbent polymer 10 holds the moisture which is absorbed by it once, good or bad of using environment of the IC card can be determined by recovering and analyzing an IC card on the market and an alarm can be given to a user whose using condition is bad. Further, a resin-like highly absorbent polymer can be easily applied on a module.

Title: Backflow blocking device
Inventor: OYA HIROSHI
IPC: B29C45/52
Filed: 1995-02-20
Abstract: PURPOSE: To make a blocking operation responsive sensitively and minimize the backflow amount of a resin by providing an extension part with a larger inner diameter than a check ring so that the moving resistance of the check ring increases, on the check ring, and forming the extension part across to an injection screw side from a valve seat in one piece. CONSTITUTION: An extension part 6b is provided at the rear of the injection screw 2 side of a check ring 6, so that the part 6b covers a valve seat metal 3, and is integrated with the extension part 6b by forming a flow path Ta for the resin between the park 6b and the metal 3. The outer diameter of the extension part 6b is larger than the inner diameter of the check ring, i.e., the inner diameter of the rear end surface 6a which comes into contact with the valve seat 3a. Consequently, the moving resistance of the check ring 6 increases. so that the moving distance of the check ring which advances following the injection screw 2 decreases at the time of initiating the injection operation of the injection screw 2. Thus the check ring 6 comes into contact with the valve seat 3a with high response and thereby the backflow of the resin is minimized.
