摘要： PURPOSE:To make air speed distribution of the front face of a filter uniform, to set the maximum air flow value of the same face to a predetermined value or less and to improve the operating efficiency of the filter by so disposing the sharpened end of a wedge-shaped square conical wind direction structure as to oppose to the section of a duct of an inlet opening in the opening. CONSTITUTION:An wind direction unit 10 and a wind direction supporting beam 11 are provided in the opening of a diffuser 2. The unit 10 is formed, for example, in a wedge-shaped square conical state, of an iron plate as its material, in a hollow state. The unit 10 is so disposed that the sectional area of a duct between the opening of the diffuser 2 and the unit 10 becomes a predetermined valued or more. The air from the diffuser 2 is collided with the unit 10 to reduce its dynamic pressure to alter the direction of the flow along the unit 10 and to feed toward a ceiling 15 or a floor 16. It is combined in front of a filter 3, its maximum air speed value is limited to a predetermined value or less, and the air speed distribution immediately before the filter 3 is made uniform.

摘要： PURPOSE:To assure uniform air temperature distribution and reduce pressure loss by installing two each of adjoining inlet and outlet headers, arranging alternately refrigerant pipes starting out and terminating at respective headers and setting the center of the inlet and outlet of an evaporator on a same axis. CONSTITUTION:Refrigerant pipes 18 in an evaporator 9 are divided into a refrigerant pipe 18 starting from a refrigerant inlet header 201 and terminating at an adjoining refrigerant outlet header 211 and a refrigerant pipe starting from a refrigerant inlet header 202 and terminating at an adjoining refrigerant outlet header 212. An arrangement of the refrigerant pipes as described herein makes the temperature of air as a whole uniform, which was put through heat exchange with each refrigerant pipe. Next, the centers C1, C0 of the inlet and outlet openings of the evaporator 9 are adjusted to be on a same axis. The pressure loss arising from the construction of a casing 14 here becomes smaller as compared with the pressure loss in a case where the center C1 of an inlet opening 22 and the center C0 of an outlet opening 23 are not on a same axis.

摘要： PROBLEM TO BE SOLVED: To exert a high resolution quickly in a compact constitution by setting a plurality of pairs of detecting apparatuses each comprising an X-ray generator and an X-ray detector via a space to a flow of a body to be detected, and carrying out detection. SOLUTION: A parcel 3' running on a conveyor is placed on a conveyor rotational guide 21 of a parcel-rotating device 8 within a shield box. An X-ray detection apparatus is constituted of an X-ray generator and an X-ray detector in pairs. X-ray generators 31, 32, 33, 34 and X-ray detectors 35, 36, 37, 38 are fixed to a fixing guide 41. Each detection apparatus is arranged on the same plane to the parcel 3'. A fan beam angle is set to be 24 deg.. The detection is carried out for every 1 deg. of a parcel rotational angle 51 deg., whereby 51 projection data are obtained by one detection apparatus. A total of 51×4=204 projection data are obtained by the four detection apparatuses. A clear pickup image is achieved when the projection data of 40 or more are collected. The 51 deg. rotation can obtain the same data as a 204 deg. rotation, reducing a scan time to 1/4.

摘要： PURPOSE:To decrease an area of an air stagnant zone in a containment and to enable a homogenization of a temperature distribution of an inside containment atmosphere, by generating a circulation flow surrounding a shielding block and also generating a secondary circulation flow accompanied by the former circulation flow at pipings. CONSTITUTION:By connecting a gamma ray shielding block area 10 and a control rod drive mechanism area around a nuclear reactor pressure vessel 2 with a duct and by activating a blower 8 placed at the intermediate part of the duct, an ascending air flow is accelerated. On the other hand, upper torus blow-off valves 6a are placed on an upper position of a containment 1, and intermediate torus blow-off valves 6m and lower torus suction ducts 7l are placed at an intermediate position and at a lower position of the containment, respectively. The ducts 7l and 6a are connected by a duct 5 and the blower 8 and a cooler 9 are placed at an intermediate position of the duct 5. A discharge outlet of the blower 8 and the duct 6m are connected and the cooler 9 and the duct 6m are also connected. Therewith, by a cooling air flow from the duct 6a, high temperatures air rising to an upper part of the containment 1 is cooled down and streams downwardly as a circulation flow. Moreover, by the cooling air flow from the duct 6m, a downward air flow along an outer wall surface of the shielding block 3 is urged to flow and forms a secondary circulation flow therewith a temperature distribution can be homogenized.

摘要： PURPOSE:To make temperature inside a car room uniform as well as to reduce the extent of load at the time of starting an air conditioner, by rotating a fan making a solar cell a power source, when a car is stopped under the blazing sun, while producing a flow of air around a car room ceiling. CONSTITUTION:Each of solar cell panels 14 and 15 is set up in the front and the rear of an automobile, comparing each output voltage of these panels by voltage comparators 161 and 162, and when a difference in these output voltage values comes to positive, switches 171 and 172 or 173 and 174 are turned on. And, when this output voltage shows such a value as being sufficient enough for operating exhaust fans 25 and 26, and detection temperature of a car room inside temperature detector 20 is more than the setting value (discomfortable temperature) and furthermore a battery driven fan operating indicator 21 shows that a battery driven fan is in a stop state, each of switches 175 and 176 is turned on. With this constitution, both new-charge and exhaust fans 25 and 26 are started, blowing off fresh air to the inside of a car room 7, and the air circulated through the inside of the car room 7 is exhausted to the outside.

摘要： PURPOSE:To measure the minute amount of the concentration of hydrogen which is present in an environment by assembling a Wheatstone bridge with hydrogen occluding metal as one sensor, and measuring the resistivity value of the circuit by using a potentiometer. CONSTITUTION:A Wheatstone bridge circuit is formed of three resistors 2 whose resistances are known, an electric resistor 1 made of hydrogen occluding alloy and a potentiometer 3. The resistance value is measured under the state wherein the concentration of the hydrogen is zero. Then, the sensor of the electric resistor 1 is held in an environment wherein the hydrogen concentration is measured for a specified time. Thereafter, the resistance value is measured, and the hydrogen concentration in the environment is measured. Thus the hydrogen concentration in the environment can be measured by the simple method.
