Abstract: PURPOSE:To improve purifying efficiency without any increase in volume of an exhaust emission control device by combining two opposed corrugated boards constituting a passage for a carrier so that they cross with each other at reverse directional angles in the exhaust emission control device provided with a carrier in which multiple passages are coated with a catalyst CONSTITUTION:An inlet pipe 1, a case 3, and an outlet pipe 2 are connected in this order, while a ceramic carrier 6 whose surface is coated with catalysts 7 is stored inside the case 3, and the carrier 6 is formed so that its cross section has a triangularly corrugated shape with apex angles and basic angles of approximately 90 deg.. These kinds of carriers 6 are laminated, so that, in vertically adjacent two layers 8, 9, the ridge line and the root line of the upper layer 8 are inclined in the positive direction at the preset angle to the macroflow direction of the whole of the exhaust gas while the ridge line and the root line of the lower layer 9 are inclined in the negative direction at the preset angle. In this way, a catalytic area is widened, and purifying efficiency is improved without any increase in the volume of the exhaust emission control device.

Title: Measuring method for position of object
Inventor: ISHII YUJI
IPC: G01S7/526
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To establish a measuring method, for the position of an object, in which a measuring error is small by a method wherein a function which is approximate to a plurality of peak coordinates in the initial wave of reflected waves is found on the basis of the peak coordinates and the reception starting point of the reflected waves in which the function is converged to 0 is found. SOLUTION: Burst waves which are generated by a wave transmission system 1 are radiated toward an object, to be measured, from a transducer 2. The radiated burst waves are reflected by the object to be measured, and they are amplified and then converted into a digital signal so as to be output to a control circuit 4. The control circuit 4 samples the peak value of a digital output at a timing synchronized with the frequency of the burst waves in the case of a reception timing period after the set delay time has elapsed, and it stores the maximum value of the respective waves primarily.  Then, a function which is approximate to peak coordinates is found by an interpolation method, the found function is computed by Newton's method, and the reception starting time of the reflected waves as the root of the function is found, and a distance and a depth up to the object are found on the basis of the difference between the reception starting time and the transmission starting time.

Title: Indirect cycle type nuclear power plant
Inventor: SUZUKI HIROAKI
IPC: G21C13/024
Filed: 1987-12-29
Abstract: PURPOSE:To achieve a smaller size and a reduction in a pressure of a containment vessel in case of a trouble, by incorporating a joint between a piping in contact with a primary side coolant within a pressure container and a joint with the pressure container thereinto while a secondary side piping from a heat exchanger is arranged outside the containment vessel. CONSTITUTION:A joint between a piping 12 in a storage pressure injection system in contact with a primary side coolant within the pressure container 2 or a piping 13 in an automatic depression system and the container 2 is incorporated into a containment vessel 5 and a secondary side piping from a heat exchanger 1, for example, a feed water pipe 10 or a main steam pipe 11 is provided outside the vessel 5. Even if the pipes 10 and 11 break, it is not necessary to contain the coolant into the vessel 5 because of a lower level of the radioactivity thereof. When the pipes 12 and 13 break, first, a pressure of a dry well 6 rises with the inflow of the coolant. But as the capacity of the dry well 6 is small to about a half, there is a limited quantity of non-condensing gas, which lowers a partial pressure of the non-condensing gas, namely, the pressure of the vessel 5 with shifting to a wet well 8 after an accident. This also causes a drop in steam pressure of a pressure suppression pool 7 because of more amount of heat radiation, thereby lowering the max. pressure of the vessel 5 by about 20%.
