Title: Method for controlling ac filter facility
Inventor: YAMANAKA KEIJI
IPC: H02J3/01
Filed: 1992-04-14
Abstract: PURPOSE:To prevent the operation of an AC filter facility in a state where the phase of the filter facility is excessively leading so as to reduce the occurrence of losses by suppressing voltage distortion caused by a harmonic current lower than a fixed limit by taking the sum of a receiving point current collecting the currents of a load and AC filter and the current of the filter facility and detecting the harmonic component of the sum, and then, controlling the opening/closing of the filter facility based on the magnitude of the harmonic component. CONSTITUTION:By installing a current transformer CT1 for detecting current to a power receiving point, all currents of a load Z and AC filter facility AF are detected. Then, by installing a current transformer CT2 for detecting currents to the circuit of the facility AF, the electric current flowing to the facility AF is detected. A controller QR fetches the current values detected by the transformers CT1 and CT2 and adds the values to each other. Then the controller QR only fetches a harmonic component from the added current and gives an opening or actuating command signal to a switch S depending upon the magnitude of the harmonic component. Therefore, the opening and closing of the facility AF can be controlled relatively easily in accordance with the harmonic generating amount of all loads.

IPC: C01D1/42
Filed: 1989-05-17
Abstract: PURPOSE: To prevent the corrosion of an evaporator by adding a formulation containing hydroquinone, pyrogallol and deionized water, into a caustic alkali aq. solution in the caustic alkali evaporator made of Ni or the like.  
     CONSTITUTION: At the time of feeding an aq. solution containing 28-32% active NaOH in the caustic alkali evaporator made of Ni, a Ni alloy or steel and evaporating by heating to concentrate, the evaporator is rapidly corroded when a trace quantity of a chlorate or oxygen is contained in the solution. The formulation containing 0.5-1.5ppm hydroquinone, 0.055-0.165ppm pyrogallol and the deionized water is added into the caustic alkali aq. solution to prevent the fact. The corrosion of the evaporator by the caustic alkali is effectively prevented by a material generated by the catalytic action of pyrogallol to hydroquinone.

Title: Memory interface device
Inventor: KOYAMA MASAYUKI
IPC: G06F11/10
Filed: 1995-05-22
Abstract: PURPOSE: To improve the reliability of a memory by outputting a signal for reporting the existence of a fixed fault to an external device when a correctable error is detected in updated data. CONSTITUTION: When reading data from a memory 20 to a BUS 8, an EDC/ECC 5 performs error detection/correction and decoding and the data are outputted through an RBUF 1 to the BUS 8. When the correctable error is detected, data having this error are error-corrected, decoded, sent to the RBUF 1 and simultaneously stored through a MUX 2 into a WBUF 3 as well. The EDC/ECC 5 encodes these error-corrected data again and writes them at a source address in the memory 20. Afterwards, the EDC/ECC 5 reads the data from this address again and performs error detection. When the correctable error is detected again, a control part 6 reports a fixed fault. Therefore, since the presence/ absence of the fixed fault such as the hardware fault of the memory is discriminated, trouble caused by leaving the fixed fault is prevented and as the result, the reliability of the memory is improved.
