摘要： PROBLEM TO BE SOLVED: To facilitate arrangement of a sensor by relaxing mounting accuracy on a magnet of the sensor which outputs a voltage, each time the magnetic field in a core, having a large Baukhausen effect, is inverted.
SOLUTION: Two pairs of magnetic groups M1, M2 where magnets 1 to the number of 2n (n:a natural number) are circularly arranged respectively are provided, and magnetic poles of magnets at the shortest distance between the groups are arranged so as to attract each other; and each magnetic group M1, M2 is made to rotate mutually in synchronism in the reverse direction about the center axis. The sensor 2 is arranged so that its length direction is in parallel with a straight line, connecting the rotational axial centers of the magnetic groups M1, M2. A magnetic field change generated by rotating M1 and M2 in reverse is applied to the sensor, to thereby enable usage without problems, even if the mounting position between the sensor and the magnets is somewhat deviated.

摘要： PROBLEM TO BE SOLVED: To eliminate misjudgment due to actual gas leakage and the usage of another gas appliance or the fluctuation in a gas pressure, and to dispense with the modification of a program of a microcomputer, when correcting instrumental errors, in the sensing of the gas leakage by the microcomputer.
SOLUTION: In the diaphram type microcomputer gas sensor, the rotation of a conversion gear A-1 is transmitted to an idle gear A-5. The rotation of the idle gear A-5 is transmitted to a small high gear A-6, and is transmitted to a magnet gear A-8, having a diameter smaller than that of a high gear A-7, via the high gear A-7 that is integrally formed with the small high gear A-6. By driving a flow rate transmission magnet 19, a flow rate pulse is generated to enhance resolution. Accordingly, misjudgment between gas leakage and usage of the gas appliance is eliminated, in which the pulses are not generated due to the fluctuation in the gas pressure. Further, there is no need to modify the microcomputer program each time, even if the conversion gear is replaced at correction of the instrumental error.

摘要： PURPOSE: To provide a pressure fluctuation absorbing device which can effectively absorb pressure fluctuation with pressure loss restrained low by a simple structure. CONSTITUTION: This pressure fluctuation absorbing device has a partition 24 for partitioning a main body 21 into air-chambers 22, 23; an introduction port 25; a discharge port 26; a cylindrical body 27 which is fixed to the upper face of the partition 24 at its lower end; and a float 28 arranged inside the cylindrical body 27. A gas introducing opening 29 is provided on the bottom of the cylindrical body 27, and the upper side of the cylindrical body 27 is closed by an upper wall 30. A sliding member 42 slides in a throttle opening 31 functioning as a variable throttle on the side wall of the cylindrical body 27 to prevent the clogging of the throttle opening 31. The small hole 32 of the upper wall 30 makes the air-chamber 33 function as a cushioning mechanism for controlling the abrupt movement of the float 28 to prevent hunting. The sliding member 41 slides in the small hole 32 with the vertical movement of the float 28 to prevent the clogging of the small hole 32.

摘要： PURPOSE: To obtain a gas meter whose replacement operation is performed easily by making a common gas meter possible to be installed without changing the mode of a gas pipe even in the mode of a gas pipe in which the gas meter is installed so as to be suspended and in the mode of a gas pipe in which the gas meter is installed so as to be put on. CONSTITUTION: The gas meter is composed of a main body part 1 in which an entrance connecting pipe and an exit connecting pipe 12 which are parallel to each other protrude upward or downward, of a metering means which is installed inside the main body part 1 and which meters a passage gas amount inside the main body part 1 and of a display 4 by which the gas usage amount is displayed on a display part 400 formed on the front on the basis of a signal from the metering means. The display 4 is installed so as to be connected to the upper end part or the lower end part in a front and rear exposed state, and it can be inversed to the front and the rear as well as to the top and the bottom with reference to the main body part 1.

摘要： PURPOSE: To facilitate the dimensional management of a metal mold for molding a fluidic element or a product by guiding a part of the injected fluid from an injection nozzle toward an alternating pressure detecting means from the downstream end part to the upstream end part. CONSTITUTION: When a fluid is blown out from an injection nozzle toward a downstream passage, the blown fluid is carried along the outer form of a target 40, and laterally distributed. It is carried along, for example, the fluid guide surface 49a of a right-hand return side wall 45a by Coanda effect. The fluid carried to the right-hand fluid guide surface 49a is partially run toward the downstream, and directed to a first discharge passage through a communicating passage 49, while it is partially directed to the upstream. Thus, an alternating pressure wave is generated by the vibrating phenomenon of the fluid blown out from the injection nozzle into the downstream + passage, this alternating pressure wave is detected by pressure wave sensors 39a, 39b, and the flow rate is measured on the basis of the detection result.

摘要： PROBLEM TO BE SOLVED: To provide a pressure variation absorber which can absorb pressure variation while suppressing deposition of dust. SOLUTION: Gas flowing in from the upstream side is guided via a pressure variation absorber 20 to a fluidic element. In the pressure variation absorber 20, a float 220 velocity moves in a case 210 according to difference in pressure on the upstream and downstream sides. The float 220 comprises an upper structure 223, a lower structure 221 and a coupling 222. Spaces between upper and lower parts of the float 220 and inner peripheral faces of the case 210 are substantially closed, while a large space 224 is provided in a medium part between the upper and lower part of the float 220 from the inner peripheral faces of the case 210. While movement of the float 220 with force duet to the difference in pressure between the upstream side and the downstream side received is secured, deposition of dust in gas to the case 210 can be suppressed.

摘要： PURPOSE: To extend the flow rate measurable range while suppressing the pressure loss within an allowable range by constituting a flowmeter from a fluidic element having an opening part opposed to an injection nozzle and a U-shaped target provided in the downstream passage from the injection nozzle. CONSTITUTION: When a fluid is blown out from an injection nozzle 23 toward a downstream passage 29, the blown fluid is carried along the outer form of a first target 40, laterally distributed, and carried along, for example, the inside of a right-hand side wall 34a by Coanda effect. Since the upstream curved part of the first target 40 is formed of a circular arc having a relatively small curvature radius, the feedback effect by the returning fluid can be more enhanced. Thus, the amplitude of an alternating pressure wave generated by the vibrating phenomenon of the fluid can be increased, and the frequency is also increased. Therefore, the flow rate measurable range can be extended to the part in which the amplitude and frequency of the alternating pressure wave are so small because of little flow rate that the flow rate can not be measured.

摘要： PURPOSE:To lessen undesirable effects of dust flowing together with gases in a pipeline. CONSTITUTION:The circulation of gases taken in through an inlet part 11 of a fluidic flow meter is limited so as to make dusts, which is flowing together with the gases, collide against a filter 52 and the gases reach the filter 52. The dusts are captured by the filter 52 and inhibited from flowing in the down stream side. Meanwhile, the gases which pass the filter go a first gas flow route 14, an openpart 16, a second gas flow route 15, and a flow rectifying member 22 in this order and go into a nozzle 21.
