Title: Reactor recirculation pump control system and its power supply device
Inventor: SAKATA TOMOTAKA
IPC: G21D3/04
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To avoid the tripping of an RID-ASD as much as possible and to secure the thermal soundness of a fuel even if a bus voltage fluctuates due to a transmission line fault or the like by detecting the behavior of the bus voltage and using a logic for running back the RIP-ASD according to it. SOLUTION: In normal operation, an RIP-ASD controls the speed of a RIP so that reactor output can be subjected to constant control according to a signal from a recirculation flow rate control system 14. When a transmission line 6 is disturbed and the voltage behavior of a bus line 3 occurs, a voltage change rate and the deviation and phase difference of three-phase voltages are detected, a value is outputted to an RIP-ASD speed control device 10 by a bus voltage change monitoring device 9, and switching is made from the control system 14 to the device 10 when a prescribed value or higher is judged, thus controlling the speed of the RIP. More specifically, when a voltage is equal to or more than a set value, neither run-back nor trip is generated in the RIP and an output frequency is reduced to continue operation.  When a voltage is equal to or less than the set value and a deviation difference and a phase difference are judged to be within the set value, a signal is outputted from the device 10, the control system is switched, the RIP starts run-back, and a reactor flow rate is reduced.

Filed: 1990-11-09
Abstract: PURPOSE:To ensure the extremely high detection sensitivity of reflected light from a sample, and simplify the constitution of an optical system by detecting the intensity of the aforesaid reflected light on the basis of a change in the oscillation line width of a laser means. CONSTITUTION:Light focused and irradiated on a sample 3 from a frequency narrow-banding laser means 1 via an optical system 2 is reflected by the sample 3, and again incidental to the aforesaid means 1 via the same optical system 2. The phase of the reflected light from the sample 3 is disordered, so long as the sample 3 is not a mirror surfaced reflector, or the phases of light from the laser means 1 and reflected light from the sample 3 are different from each other, so far as optical length between narrow-banded laser and the sample 3 happens to be equal to the integer of multiplication of laser wavelength. Consequently, a noise is induced in the oscillation mode of the frequency narrow- banding laser means 1 and oscillation line width expands. This expansion of line width changes very sensitively to the intensity of return light to the laser means 1, or reflected light from the sample 3. According to the aforesaid construction, the detection sensitivity of the reflected light becomes extremely high, and an optical system can be simplified.

Filed: 1989-11-24
Abstract: PURPOSE: To prevent the contamination of a wafer surface and to improve drying efficiency by substituting washing fluid with drying vapor and directly substituting washing fluid on a surface at a speed at which liquid drips do not remain. CONSTITUTION: The upper part of a container 12 is filled with drying vapor 32, and washing liquid 30 is partially filled as the boundary 34 of gas-liquid-solid is pushed downward through a wafer in a wafer instructing container 18 at an upper side. When saturated drying vapor flows into the container 12 and drying fluid is substituted for washing fluid from the wafer 16 on the boundary 34, drying fluid is mixed with washing fluid, and a clear drying fluid layer is formed on the upper part of washing fluid. The final washing fluid and drying fluid layer flows out of the container 12, and is made to flow into a boiler 14. When the boundary 34 drops at a sufficiently low speed, water/isopropanol boundary removes all water drops and the liquid drips of azeotrope from the wafer 16 as a liquid face drops. Thus, drying can be surely executed, without contaminating the surface of an object.

Abstract: PURPOSE: To switch a high voltage DC power source with a compact structure by extinguishing an arc by forming the arc between a pair of fixed contactors in the case of separating bridge connection between a movable contactor and a pair of fixed contactors. CONSTITUTION: A power source terminal 14 is connected to the positive side of a high voltage power source, and a power source terminal 16 is connected to its negative side. A magnetic field crossing an arc chamber containing a fixed contactor 54 is pointed in the direction for proceeding forward from a space. An arc is formed between the fixed contactor 54 and a movable contactor 70d and between it and the other movable contactor 70d by separation. Arcs 120 and 122 tend to expand, and force imparted by the magnetic field moves the arc 120 toward a conductor 48 along an extending part 70e of a movable contactor 70. The arc 120 becomes long, and while its voltage is increased, the arc 122 also moves in the leftward direction by a bias of the magnetic field.  An electric current passage extending up to the contactor 70 from a conductor 46 and up to the conductor 48 from the contactor 70 is extinguished here, and the arc 122 is similarly extinguished.
