Title: Reactor isolation cooling system
Inventor: KIKUCHI TOSHIO
IPC: G21C15/18
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To improve an operation-maintaining capacity by releasing a pervious signal in the case when a dry well pressure-high or reactor water level-low L1.5 signal is detected when a diaphragm pressure-high signal is generated and a steam line inner isolation valve and an outer isolation valve close, and an RCIC turbine trip signals are generated due to the damage of a rupture disk. SOLUTION: In the case when a first-stage rupture disk 5 is damaged, a pressure between the first-stage rupture disk 5 and a second-stage rupture disk 6 increases, which is detected by a pressure gauge, thus a diaphragm pressure high signal 7 is generated. Normally, a steam line inner isolation valve 3 is closed, an outer isolation valve 4 is closed, and an RCIC turbine 1 is tripped. At this time, only when an LOCA signal exists, the diaphragm pressure high signal 7 is erased, and the steam line inner isolation valve 3 and the outer isolation value 4 are opened and the RCIC turbine 1 cannot be tripped, thus achieving the continuos operation of the RCIC.

Title: Electrolytic graining treatment of aluminum base for planography
Inventor: NAKANISHI HARUO
IPC: B41N3/00
Filed: 1987-12-11
Abstract: PURPOSE:To efficiently provide an aluminum alloy plate, for use as a base, with a uniform and dense pit shape, by using an alternating waveform current the polarity of which is alternately changed so that the waveform current value at the time of an anode instantaneously increases from zero to a peak current and then gradually decreases. CONSTITUTION:A cleaned aluminum plate is subjected to an electrolytic graining treatment. The waveform of an electrolyzing current used in the treatment must be an alternating waveform current the polarity of which is alternately changed and in which the waveform current value at the time of an anode instantaneously increases from zero to a peak value and then gradually decreases, whereas the waveform on the cathode side may have any shape. For obtaining a uniform pit diameter and a uniform pit distribution, it is necessary that the quantity of electricity at the time of the cathode be equal to or smaller than the quantity of electricity at the time of the anode. The gradual decrease means a decrease over a period of time longer than the rise time, the period being at least 1.5-100 times the rise time. The ratio of anode time to cathode time may vary in the range of 0.4-2.5.

Title: Carbon brush
Inventor: SUZUKI KATSUNORI
IPC: H02K13/00
Filed: 1989-12-01
Abstract: PURPOSE:To prevent a film of a harmful insulating material from being formed between a carbon brush and a commutator by forming the resin film obtained through adding powder of an inorganic material to a resin including an oil or an oil compound and through mixing them with each other on the surface of the carbon brush. CONSTITUTION:Acetone is added to a nondrying alkyd resin including a saturated fatty acid and the resultant one is made to be a dispersed liquid by adding aluminum powder to it while agitating it. Then, a brush obtained by working an electric graphite carbon material of a pitch coke group is dipped into the dispersed liquid and is pulled up from inside it. After drying it by use of a wind, a film is formed on the surface of the brush by heating and increasing temperature. The friction coefficient and the varying rate of the friction of the brush are small and their increases caused due to a lapse of time are small too. Also, the non-spark zone is wide too and the communication is good. Therefore, the good sliding contact can be maintained between the brush and the surface of the commutator without laying a film of an insulating material being harmful to the sliding and communicating characteristic of the brush between them.
