Patent JP-H0886674-A (JP)
Title: Capacity type electromagnetic flowmeter
Inventor: ISHIKAWA FUMIMITSU
IPC: G01F1/58
Filed: 1994-09-20
Abstract: PURPOSE: To detect the liquid level in a conduit by feeding the output from a pair of electrodes for detecting unfilled state, formed on the conduit, to a differential amplifier in addition to the output from a pair of electrodes for detecting the flow rate, subtracting or dividing the outputs, and detecting the noise component included in an output signal in unfilled state. CONSTITUTION: The electromagnetic flowmeter comprises an excitation coil 21 being driven through an excitation circuit 21a. A conduit 30 for feeding a measuring fluid is provided with a pair of upper capacitive electrodes (unfilled state detection electrodes) 31a, 31b and a pair of lower capacitive electrodes (flow rate detection electrodes) 32a, 32b. In a filled state, outputs from the pair of lower electrodes 32a, 32b and a first differential amplifier 34a are processed in a flow rate detection circuit 35a thus measuring flow rate. In an unfilled state, the fields of both pairs of electrode do not vary but the liquid level lowers and thereby the signal detected by the pair of upper electrodes 31a, 31b has a lower level than the signal detected by the electrodes 32a, 32b.  Consequently, a third differential amplifier 34c produces an output and a circuit 35b for detecting unfilled state produces an output corresponding to the liquid level in the conduit.

Title: Water direct jet type fuel cell system
Inventor: HORIGUCHI MUNEHISA
IPC: H01M8/04
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To surely supply liquid-state water to each air electrode of a cell stack by installing a nozzle which is fixed to the side surface of an air manifold and jets water into the manifold. SOLUTION: A water supply system 50 is a closed system in which water of a tank 53 is supplied to an air manifold 4, recovered with a water condenser 51, and returned to the tank 53. Water of the tank 53 is forcibly supplied to a nozzle 55 arranged in an air manifold 45 with a pump 61, and jetted to the surface of an air electrode in a fuel cell stack 2. Since the water preferentially takes latent heat from air, the evaporation of water from an electrolyte film on the air electrode side is prevented, and the electrolyte film on the air electrode side always keeps a uniform moist state. Since the water supplied to the surface of the air electrode also takes heat from the air electrode itself to cool it, the temperature of the fuel cell stack 2 can be controlled.

IPC: G21C5/06
Filed: 1988-09-09
Abstract: PURPOSE: To prevent a strong vibration to a fuel rod by adjusting flow along the inside of a cluster guide sleeve. CONSTITUTION: A first sub structure is formed by a grid 12, an upper piece 16, and a guide tube 20 fixed by the upper piece 16 and a second sub structure is formed by a guide tube other than the guide tube 20 and a lower piece 18 where the guide tube is connected as a fuel assembly 10. An adapter plate 46 is fixed to the guide tube 20 and a shroud 48 is arranged upward so that a coolant is retained on an upper core plate 49 around a passage for delivering the coolant to each guide sleeve 50. As a result, only the flow of upward coolant passing through the guide tubes 20 and 24 appears within an inner volume and passes to the sleeve 50 through the passage of the upper core plate 49, thus releasing an outer pressure p1 of the shroud 48 from a pressure PO at the inner side of the inner volume.
