Title: Floor coating process
Inventor: KUBO KEIZABURO
IPC: C09D5/00
Filed: 1988-07-11
Abstract: PURPOSE:To effectively prevent the expansion, peeling and cracking, etc., of a coated floor by applying crystal-increasing agent produced by adding a silicofluoride and an unsaturated bivalent carboxylic acid to a Portland cement composition and applying a floor on the crystal-increasing agent layer. CONSTITUTION:A crystal-increasing agent is produced by compounding (A) a Portland cement composition containing 20-40wt.% of CaO, 1025wt.% of SiO2 and 10-25wt.% of MgO with (B) a silicofluoride (e.g., SiF6) and an unsaturated bivalent carboxylic acid. The agent is applied to the surface of a mortar or concrete and a floor is applied to the layer of the agent. The crystal-increasing agent promotes the growth of crystal in the pores and voids of concrete, etc., by the reaction with moisture and suppresses the deterioration of concrete.

Title: Feedback amplifying circuit
Inventor: SATOU ICHITAROU
IPC: H03F1/34
Filed: 1979-12-28
Abstract: PURPOSE: To avoid the effect of impedance of a resonance circuit, by connecting the resonance circuit and a resistor between the main electrode of a transistor at the poststage and the power supply, and feeding back the potential produced across this resistor to the prestage.  
     CONSTITUTION: The frequency characteristics without a feedback loop and a resonance circuit 20 are right-down ones in which the level is lowered as frequencies increase. Further, when the middle band is corrected by inserting the circuit 20, a peak is developed and it is not in good condition regardless of the effect, since  high band characteristics are lowered. Thus, negative feedback is made with resistors 21 and 25 without the circuit 20. Thus, the high band part of the frequency  characteristics is increased to obtain flat characteristics. With this state, when  middle band is corrected through the insertion of the circuit 20, favorable characteristics in which the peaks have almost symmetry, are obtained. Further, the potential at the connecting point between resistor 21 and circuit 20 in negative feedback is independently of the impedance of the circuit 20. Thus, the frequency correction for a plurality of parts such as high and middle bands can be made by using the same amplifier.

Title: Leaking-defect detecting material
Inventor: YASUTAKE AKINORI
IPC: G01M3/20
Filed: 1984-08-20
Abstract: PURPOSE:To conduct the test safely and to prevent the occurrence of hindrance to painting on a material to be tested after the test, by coloring a gas detecting material with a dilute gas, and providing a structure wherein the detecting material does not remain in the material to be tested. CONSTITUTION:A detecting material P is attached to a welded part S of a tank T along the logitudinal direction so that a gas adsorbing agent is contacted with the welded part S. Then harmless mixed air including a minute amount of ammonia gas is compressed into the tank T by a compressing means, which is not shown. When a defect part is present in the welded part S, the compressed gas in the tank T leaks. The ammonia gas in the compressed gas is arrested by the gas adsorbing agent 3 in the gas detecting material P. The metallic ions in the gas adsorbing agent 3 is discolored. By observing the discolored part, the defect part in the welded part S can be readily detected. After the detecting work is finished, both a film body 1 and the gas detecting agent 3 are completely removed together. Therefore, the removing man-hours can be reduced. Any hindrance to the following painting and the like does not occur.

Title: Magneto-optical recording medium and reproducing method of magneto-optical recording information using the same
Inventor: NAKAJIMA JUNSAKU
IPC: G11B11/105
Filed: 1994-07-25
Abstract: PURPOSE:To improve the surface recording density without making an apparatus large in size and increasing the power consumption, by masking information being present in areas other than the central part of a light application area and in its vicinity CONSTITUTION:When a reproducing light beam 21 is applied to a readout layer 3 from the base 1 side, the temperature around the central part and in the vicinity thereof rises and becomes higher than that in the peripheral part thereof. When an external magnetic field Hr is impressed, information of a recording layer 5 is transferred to the readout layer 3 only in the part of the rise in the temperature in the central part of the beam 21 and only that part participates in reproduction of the information. In other words, transition metal sub-lattice magnetization of the layer 3 in the part other than that of the rise in the temperature, masks the information of the layer 5. At the time when the beam 21 shifts and the next bit is reproduced, the temperature of the part already reproduced lowers to room temperature and the transition metal sub-lattice magnetization of the layer 3 is directed in the direction following the magnetic field Hr, not following the transition metal sub-lattice magnetization of the layer 5, due to an exchange coupling strength from the layer 5. Thereby, the information of the reproduced part can be masked. Accordingly, mixing-in of a signal from an adjacent bit which causes noise, is eliminated.

IPC: F16J13/02
Filed: 1985-08-06
Abstract: PURPOSE:To simplify a manufacturing process for the whole unit of a vessel, by arranging seals of cover members to the inner from connecting pins in an opening part of the vessel. CONSTITUTION:An internal pressure (p) acts in the radial direction on a peripheral side wall 2 between seals 4d, 5d of upper and bottom covers 4, 5 while acts in the axial direction also on the upper and bottom covers 4, 5. A vessel, providing no internal pressure (p) directly acting on the peripheral side wall 2 and annular joints 2b, 4b, 5b in the upper or the lower than the seals 4d, 5d, generates stress in the axial direction between the seal 4d or 5d and connecting pins 6, but stress in the peripheral direction gradually decreases as a position separates distant from the seals 4d, 5d. Consequently, the vessel decreases a load as small as possible in a part of the annular joints 2b, 4b, 5b providing the connecting pins 6 to be extended.
