Title: Hardenable composition and formation of water glass- blast furnace water-granulated slag-based hardened material
Inventor: UEDA YASUNARI
IPC: C04B28/26
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To obtain a composition having excellent controllability of hardening rate and thixotropic properties by including water glass, blast furnace water- granulated slag, a starch and an alkali hydroxide. SOLUTION: This composition comprises 100 pts.wt. of water glass, 30-150 pts.wt. of blast furnace having 3,800-8,500 m2/g Blaine value, 2-12 pts.wt. of a starch such as corn starch, etc., a fixed amount of an alkali hydroxide such as sodium hydroxide, etc., and optionally 2-25 pts.wt. of a clay such as kaolin, etc., for adjusting a viscosity. The viscosity of the composition at 25 deg.C is 1,000-20,000 cps. Since the hardened material has resistance to most substances in a hardening process, defective hardening, etc., will not occur. The material has a function of sticking to most substances after hardening and is useful as a solidifying material for waste. Since the hardened material contains water glass, it has excellent adhesiveness to a nonpolar substance such as a plastic, etc., and is useful as an extender for a polystyrene foam.

Title: Driving circuit of differential transformer
Inventor: FURUTA TADASHI
IPC: G01D5/22
Filed: 1984-10-15
Abstract: PURPOSE:To improve the detection accuracy and linearity in the actual using stage by providing a constant current circuit which makes oscillation output into constant current and widening the range for measuring displacement by a differential transformer. CONSTITUTION:The AC current supplied to a primary coil 2 of the differential transformer 1 is made always constant regardless of the impedance and resistance value of the primary coil 2 thereof if the resistance values R1-R4 of resistors 10-13 are set at the relation R4/R3=R2/R1. As a result, the primary current of the transformer 1 can be made constant even if the impedance of the coil 2 changes according to the position of a core 5 and the range where the displacement of the core 5 and the secondary output voltage maintain the linearity can be thereby increased, by which the range for measuring the displacement by the transformer 1 can be widened. The primary current is made constant even if the resistance value of the coil 2 changes according to the temp. displacement and therefore there is no possibility of deteriorating the detection accuracy in the actual use and the linearity.

Abstract: PURPOSE:To improve the quality of a copied picture and to simplify the adjusting work by switching an applied voltage to an applied voltage to an applied voltage for main electrifying operation and an applied voltage for transfer electrifying operation and varying these applied voltages independently of each other. CONSTITUTION:In the first cycle (main electrifying operation) of a photosensitive body 1, a switch 3 is switched to the side of a variable resistor 10, and the output of a high voltage generator 4 is applied to a corona charger 2 through the resistor to perform main electrification. Thereafter, an optical system 6 is used to expose an image. A next destaticizing lamp 7 does not act because a switch 8 is cut off, and development is performed in a developing device. In the second cycle (transfer electrifying operation) of the photosensitive body 1, the switch 3 is switched to the side of a resistance 11, and the ouput of the high voltage generator 4 is applied to a corona charger 2 through the switch 3 to perform transfer electrification. The image pases through the optical system 6 which does not expose the image, and the destaticizing lamp 7 irradiates light because the switch 8 is closed, and the cleaning action is performed in the developing device 9 to complete the copying process. Since applied voltages are varied independently of each other, the quality of copied pictures is improved.

Title: Manufacture of plate for alkaline storage battery
Inventor: SUZUKI SHIYOUGO
IPC: H01M4/28
Filed: 1983-11-18
Abstract: PURPOSE:To decrease the number of active material impregnation cycles and reduce raw material loss by rinsing a substrate with water or dilute nitrate solution after a nickel substrate was impregnated with a nitrate and heated. CONSTITUTION:A porous nickel substrate is immersed into a molten solution or concentrated aqueous solution of nickel nitrate or cadmium nitrate. Nitrate is impregnated into the substrate and heated to fix the nitrate in the substrate. After the nitrate was fixed, the substrate is rinsed in water or dilute nitrate solution. The nitrate impregnated in the inside is difficult to dissolve but only the nitrate on the surface is effectively removed. When the substrate is immersed in potassium hydroxide solution, nitrate is converted into hydroxide. Since the amount of nitrate to be impregnated in the nexed process is increased, the number of impregnation cycles is decreased. Water or dilute nitrate solution used in rinsing is used for concentration adjusting. Therefore, raw material loss is also reduced.

Title: Method for obtaining measured quantity and circuit device for performing this method
Inventor: HANSU REOPORUTO
IPC: G01D3/02
Filed: 1992-08-13
Abstract: PURPOSE: To remove effect as caused by a thermoelectromotive force in a lead to individual resistances and a contact potential at a switch. CONSTITUTION: This method is to determine a voltage drop in a stabilized reference resistance of a temperature characteristic for the measurement of temperature. In this method, four voltage drops are measured and a difference is formed from two each of the voltage drops. A quotient is obtained from the difference using it as yardstick for a measuring quantity. In this manner, the four voltage drops are determined to obtain a voltage drop. Hence, a measuring current (Im+ ) flows through a measuring resistance and a negative measuring current(Im- )flows through a measuring resistance. The positive measuring current (Im+ ) flows through a reference resistance and the negative measuring current (Im- ) flows through the reference resistance.  Then, a difference is generated between first and second measured values, a difference is generated between third and fourth measured values and then, a quotient is formed between both the differences.
