Title: Hot water supply device
Inventor: ONODERA SHUICHI
IPC: F24H1/10
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To make it possible for an apparatus itself to detect an abnormal state, such as a crushed bypass flow passage in automatic mode in a hot water supply device having a bypass flow passage. SOLUTION: A water supply pipe 2 of a hot water supply heat exchanger 1 is connected to a hot water supply pipe 5 with a bypass passage 12. The hot water which comes from the hot water supply heat exchanger 1 is mixed with water which comes from the bypass passage 12 with a mixing ratio control valve 13, thereby supplying hot water whose temperature is specified. A control device 10 sets a mixing ratio between hot water and water of the mixing ratio control valve 13 so that the flow rate of water flowing in the bypass flow passage 12 may be a reference flow rate ratio to a total water supply flow rate during hot water supply operation. On one hand, the reference flow rate flowing in the bypass flow passage 12, which is equivalent to the reference flow rate, is determined by computation.  The determined reference flow rate and the measured bypass flow rate detected with a bypass flow rate detection sensor 15 are compared. When the measured flow rate is out of an allowable range of the reference flow rate, it is considered produce something abnormal, for example, a crushed area has been created in the bypass passage 12, thereby outputting an error signal.

Title: Neutron collimator
Inventor: UEDA KIYOSHI
IPC: G21K1/02
Filed: 1990-02-15
Abstract: PURPOSE:To exactly detect the concn. of plutonium by providing a neutron absorber container and a thermal neutron barrier which is housed in the neutron absorber container by maintaining the thickness to about the diffusion distance of thermal neutrons while enclosing a neutron detector. CONSTITUTION:The thermal neutron barrier 18 made of polyethylene is housed in the neutron absorber container 17 in the same manner as the outer side of the neutron absorber container 17 and the neutron detector 14 is disposed nearly at the center of this thermal neutron barrier. Since a material having the neutron absorbing effect and a small thermal neutron moving distance is used for the thermal neutron barrier 18 the neutrons passed through a measuring window 13 are hardly absorbed in a B4C plate 15 as the neutron absorber. Further, the thickness of the thermal neutron barrier 18 is confined to the diffusion distance of the thermal neutrons or to the thickness up to 2 times this distance at the most and, therefore, the ratio of the neutrons to be detected in the neutron detector 14 increases. The concn. of the plutonium is thus measured without worrying about the influence of the neutron background from other pulse columns.

Abstract: PURPOSE:To reduce the unbalance force functioning on a main valve by arranging an openable/closable sub valve at the upstream side of a through hole made through the valve body of a swing check type steam valve. CONSTITUTION:When an emergency device is reset under fully closed state of a main valve 16 and a sub valve 19, the emergency oil for opening the valve is supplied to the hydraulic cylinders 13, 26 while simultaneously the hydraulic pressure is applied on said cylinders 13, 26.
