Title: Corrosion suppression of metal in water system and suppressing method of silica based scale
Inventor: TAKAHASHI KUNIYUKI
IPC: C02F5/00
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To effectively suppress the corrosion of a metal in a water system and to prevent the generation of a silica based scale by allowing water to contact with a bicarbonate ion type anion exchange resin and hydroxide ion type basic anion exchange resin. SOLUTION: A part of the water in the water system is let flow from pipings 11 and 11A to an anion exchange tower 1 filled with an HCO3 <-> type anion exchange resin 1A. Residual water is let flow from pipings 11 and 11B to an anion exchange tower 2 filled with an OH<-> type anion exchange resin 1B. An effluent (treated water) of the anion exchange towers 1 and 2 is supplied to the water system via pipins 12A, 12B and 12. The water let flow the anion exchange tower 1 is brought into contact with the HCO3 <-> type anion exchange resin 1A and the incorporated corrosive ion such as Cl<-> and SO4 <-2> is subjected to ion exchange between the HCO3 <-> . The corrosive ion incorporated in the water and let flow the anion exchange tower 2 is subjected to ion exchange with the OH<-> , but silica in the water is also subjected to ion exchange with the OH<-> at this time.

Title: Azimuth meter for car
Inventor: UENO YASUSHI
IPC: G01R33/02
Filed: 1991-12-18
Abstract: PURPOSE:To obtain a precise center coordinate position of an output circle by setting an initial value as center coordinates of an output circle, involuting and summing the difference between the distance, on the coordinate system, between the initial value and the output value and the radius of the output circle, and arithmetically processing for minimum involution sum so as to correct the center coordinate position of the output circle. CONSTITUTION:In a car azimuth meter, earth magnetism component detected by an earth magnetism azimuth sensor 1 is decomposed into two components mutually orthogonal, and the travelling direction of the car is obtained based upon the direction originating from the center coordinate position of an output circle. In an output value storing means a, the output value sequencially outputted from the earth magnetism azimuth sensor, while running, is stored. In an initial value calculating means b, the average value of the stored output value is calculated for calculating the initial value of the center coordinate position of the output circle. In an involution sum calculating means c, the involution sum of the difference between the distance, on the coordinate system, between the initial and output values and the radius of the output circle given based upon the initial value is calculated. In a correction amount calculating means d, the correction amount of the initial value is calculated, and in an output circle correcting means e, the center coordinate position of the output circle is corrected based upon the correction amount.

Title: Hybrid integrated circuit
Inventor: KATAYAMA HIDEAKI
IPC: H01P1/00
Filed: 1990-11-28
Abstract: PURPOSE:To miniaturize a circuit by forming a micro strip line on a dielectric substrate by a resistor. CONSTITUTION:A micro strip line 3 consisting of the resistor is provided on a dielectric substrate 2 provided with a grounded conductor substrate 1. Since the line consists of the resistor in this structure, it is unnecessary to connect a resistor in series to the micro strip line. Consequently, the circuit is miniaturized.

Title: Lead-acid battery
Inventor: YOSHIHARA YASUYUKI
IPC: H01M4/73
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To provide a superior highly efficient discharge cycle characteristic by setting the measure square area of a negative electrode lattice body, using a pole plate by filling an active material in a current collector composed of a lattice body which is smaller than the measure square area of a positive electrode lattice body. SOLUTION: A measure square area of a negative electrode lattice body is set to be not more than 50% of the measure square area of a positive electrode lattice body. An expanded lattice body worked from a belt-like sheet composed of lead or a lead alloy is preferably used as the lattice body. Through such a constitution, reactivity of a negative electrode is uniformized/improved by increasing the contact area of an active material and the lattice body in the negative electrode and reducing an average distance between active material lattices.  In a positive electrode, capacity is regulated by enlarging a measure square of the positive electrode lattice more than that of the negative electrode, and in the negative electrode, a utilization factor can be restrained to be lower than capacity of a pole plate, and since charge receiving property of the negative electrode can also be improved, the highly efficient discharge cycle service life can be improved by suppressing the accumulation of lead sulfate.

Abstract: PURPOSE:To prevent a pressure roller from getting stained by resin and manufacture information recording mediums efficiently by providing a recessed section on a pressure roller to correspond with an open section of a base and moving the pressure roller in a manner that said recessed section is overlapped with the opening section. CONSTITUTION:A disc base 1 is pressed to a disc stamper 3 by using a pressure roller 10 provided with a recessed section 10A on a pressing surface. The pressure roller 10 rotates synchronously with the movement of the disc tamper 3 in a manner that the recessed section 10 and a central opening section 1A of the disc base 1 are overlapped when the disc base 1 is pressed.
