Title: Quick setting cement composition and quick setting mortar composition
Inventor: SASAGAWA YUKIO
IPC: C04B28/14
Filed: 1990-06-20
Abstract: PURPOSE:To obtain a quick setting cement composition having excellent quick- setting property and strength-developing property, keeping the strength over a long period and giving a pigment-colored product free from mottling by compounding white cement with gypsum and an alumina cement at specific ratios. CONSTITUTION:The objective quick setting cement composition is composed mainly of white cement and a quick setting material composed of gypsum and alumina cement at a weight ratio (gypsum/alumina cement) of 0.1-5. The major cause of the coloring of Portland cement is explained to be Fe2O3, TiO2 and R2O3 impurity components such as Mn2O3 and, among the above impurities, the influence of F2O3 is supposed to be the largest. Consequently, the white cement used in the present composition preferably has an Fe2O3 content of <0.5% and, especially, <=0.3% to give a brilliant pigment color when combined with a pigment.

Filed: 1977-12-28
Abstract: PURPOSE: To provide easy control of abnormal rises in the steam pressure inside a hot-water reservoir by forming a steam condensation zone in the upper part of a return hot-water reservoir.  
     CONSTITUTION: A condensation zone 5 is formed in the upper part of a return hot- water reservoir EC. Hot water in a bubble generator 2 is heated by a burner 1, then pumped up into a hot-water reservoir 3 through a gas-liquid riser pipe 2a by the bubble pump-up effect, to be separated from gases. Then the hot water flows through a forward pipe 7 into a radiator 8, where it releases its heat, and returns to the reservoir EC via a return pipe 6 and then to the bubble generator 2 via a return pipe 4b. At the same time, the steam in the hot-water reservoir 3a flows through a homo-pressure pipe 4a into the upper part of the reservoir EC, where it comes in contact with the lower-temperature return hot-water which flows down the spiral trough 5a in the condensation zone 5. Thus the steam condenses to control abnormal rises in steam pressure inside the reservoir 3a.

Title: Earth isolation amplifier
Inventor: MIYASHITA AKIRA
IPC: H03F3/34
Filed: 1986-07-07
Abstract: PURPOSE:To remarkably reduce the noise caused by the difference in the grounding system over a wide frequency range from a low frequency to a high frequency in the audible frequency band by adding resistors and a capacitor. CONSTITUTION:The resistors R10, R11 and the capacitor C12 form an AC component division circuit 3, where an earth noise component is fed to an emitter of a transistor (TR) Q1 via a resistor R4. The TR Q1 acts like a common base circuit to the noise component. On the other hand, the TR Q1 acts like a common emitter circuit to the noise component fed to the base of the TR Q1. Thus, both the noise components are superimposed on each other in opposite phase at the collector of the TR Q1 and they are cancelled, then the noise component at the collector output is suppressed remarkably. In connecting the resistor R11 and the capacitor C12 in parallel, the low and high frequency components of the noise are fed back and the S/N over the wide band is improved.

IPC: H01B7/24
Filed: 1991-06-06
Abstract: PURPOSE: To safely and surely install a cable system in the sea from a cable tank by avoiding rotation-induced damage to a part that is less rigid to torsion in cable. CONSTITUTION: A device preventing torque concentrating on a heavily armored cable part from being abruptly applied to a lightly armored cable part connected next to it during installation of a submarine cable system is described. A pair of helically wound steel-armored rods rigidly connected to the heavier cable part forms a tubular extension which extends first several feet of light cable. The rods resist rotation since they make rubbing contact with a cable engine drum. Therefore, the covered cable in a rod tube device rotates only by the same extent as the tube. The rotation produced is fully within a range safely permitted per unit cable length.
