SOLUTION: A throttle valve 17 which opens and shuts an air intake passage is installed in the air intake passage of an internal combustion engine. A first sensor part 161 is installed in the air intake passage in the upstream side of the throttle valve 17. A second sensor part 141 is installed in the air intake passage in the downstream side of the throttle valve 17.

| (57)【要約】 ガスセンサと、ガスセンサの上流および下流の制流部とを備える非感圧ガスプロセス装置。 制流部によって、ガスセンサの上流および下流において圧力が低下するため、ガスセンサは、上流および下流それぞれにおける圧力変動から保護される。 その結果、ガスセンサおよびガスプロセス装置全体が圧力変動に対して無感応になる。 非感圧性を実現できるガスプロセス装置には、マスフローコントローラだけでなく、その他のタイプの装置も含まれる。 | ||||||

| PROBLEM TO BE SOLVED: To simplify the structure of a device so as to facilitate assembling and reduce the size by arranging a flow strainer between an upstream flange of a meter and a flange of an upstream pipe, and a limiter between a downstream flange of the meter of an expander and a flange of a downstream pipe. SOLUTION: A flow conditioner, a flow strainer 10, a flow meter (meter) 20 and a silent flow limiter 30 are connected to each other extending from the upstream end toward the downstream end. That is, the strainer 10 is arranged between a flange 51 of an upstream pipe 50 extended from an expander- adjuster and an upstream flange 204 of the meter 20. The limiter 30 is arranged between a downstream flange 404 of the expander 40, or a downstream flange 205 of the meter 20 if the expander 40 is omitted and a flange 71 of a downstream pipe 70. Thus, the whole structure of the device can be simplified so that the length is below about the quadruple of the regular diameter of a pipe to which the device is connected. | ||||||

| PURPOSE: To suppress the fluctuation of the flow rate of evaporated gas due to the fluctuation of atmosphere by connecting a container having specified pressure to a discharging part when the flow rate of the evaporated gas in the very-low-temperature (cryogenit) container is measured. CONSTITUTION: Evaporated gas 3 of a freezing mixture 2 enters into a gas discharging tank 7 through a gas-mass flowmeter 5 with the quantity of heat which intrudes into a very-low-temperature container 1 from the outside. A solenoid valve 11 for adjusting the amount of the discharged gas in the tank 7 is initially 'closed'. The pressure in the tank 7 is increased when the evaporated gas flows in. An air pressure sensor 8 is provided in the tank 7. The output signal from the sensor is sent into a solenoid-valve controlling device 10. When the pressure in the tank 7 reaches the preset pressure value or higher which is slightly higher than atmospheric pressure, the device 10 opens the solenoid valve 11 for adjusting the amount of the discharged gas. The opening degree of the solenoid valve 11 is adjusted and controlled by the output signal of the sensor 8 so that the pressure in the tank 7 becomes constant. Thus, the fluctuation of the flow rate of the evaporated gas is eliminated, and the highly accurate measurement can be performed in a short time. COPYRIGHT: (C)1992,JPO&Japio | ||||||

A power generator 100 for use to generate power for metrology hardware like gas meters and flow measuring devices. The power generator 100 may use flame-less combustion that creates heat from fuel gas. The heat causes a temperature differential. In one implementation, the power generator 100 may include a thermal electric generator 140 that generates an electrical signal in response to the temperature differential.
