81 Device for controlling flow rate of fluid JP13334781 1981-08-27 JPS5835419A 1983-03-02 SANO SHIGERU; SAKURAI KATSUMI; ONO TATSUO; ATAGO KAZUO; NOGUCHI HARUHIRO
PURPOSE:To make it possible to control the flow rate over the broad range, by providing a orifice for measuring a large flow rate and an orifice for measuring a small flow rate, measuring the flow rate by changing the orifice in response to the flow rate, thereby controlling flow rate. CONSTITUTION:The flow rate of gas is measured by the orifice 3g for measuring the large from rate and the orifice 4g for measuring the small flow rate. The measured result is outputted from a flow rate oscillator 13g and inputted to an operating device 9. The operating device outputs the operated result, and a regulating valve 8g is controlled. When the amount of the gas is reduced owing to an accident and the like, a first cut off valve 7g is closed by the output of the operating device, and flow rate is measured by only the orifice 4g for measuring the small flow rate. The flow rate is controlled by regulating the regulating valve 8g. In this way, the flow rate is controlled from the large flow rate to the small flow rate.
82 Flow rate measuring method JP10151881 1981-06-30 JPS582706A 1983-01-08 HATSUTORI TAKAAKI
PURPOSE:To make a high-precision measurement possible with a single measurer independently of the magnitude of flow rate, by installing plural pressure taking- out points in a flow passage and switching them to connect them to a differential pressure measurer in accordance with the flow rate. CONSTITUTION:Plural pressure taking-out points are installed in a flow passage, and a set of pressure taking-out points to be selected is determined in accordance with the flow rate of a fluid, and pressure values of the selected set of pressure taking-out points are measured to calculate the flow rate of the fluid. For example, by the switching of a three-way cock 8, a differential pressure P1- P2 between pressures at pressure taking-out points A and D is applied to a differential pressure measurer 7 for a low flow rate, and a differential pressure P1-P3 between pressures at pressure taking-out points A and G is applied to the measurer 7 for a high flow rate. The flow rate is measured by the permanent pressure loss method for a high flow rate, and the method is switched to the vena tap method to measure the flow rate for a low flow rate.

PURPOSE:To measure wide-range refrigerating performance precisely and easily by providing valves before or after orifices arranged in parallel to a flow passage, and providing by-pass pipes, which have valves, before and after the orifices. CONSTITUTION:At a low pressure side between a compressor 1 and a heat exchanger 6, orifices 9 and 10 differing in diameter are provided in parallel. First, valves 11 and 12 provided before the orifices 9 and 10 are closed, and the valve 14 of a by-pass pipe 13 is opened, constituting a cycle. Then, the valve 12 before the orifice 10 for the large quantity of flow is opened, and the valve 14 of the by-pass pipe 13 is closed gradually, constituting a cycle. When the quantity of flow has a margin, the valve 14 of the by-pass pipe 13 is opened, and the valve 12 is closed; and the valve 11 of the orifice 9 for the small quantity of flow is opened, and the valve 14 is closed gradually, constituting a cycle. Thus, wide- range refrigerating performance is measured precisely and easily.

Detecting a leak, or the like, with high accuracy on the basis of pressure and a flow volume acquired during use of fluid is made possible. A volume of gas flowing through a flow path 102 is measured by a flow volume measurement unit 106, and pressure is measured by a pressure measurement unit 108. Measured flow data and measured pressure data are input to an analysis unit 112, to thus analyze following of a pressure change by a flow volume change. An amount of flow volume change responsive to an amount of pressure change of a predetermined level or more is classified into a plurality of ranges by means of a predetermined threshold value, and a following flow value change is determined on the basis of determination conditions of the respective ranges of amounts of flow volume changes.

Apparatus and methods for delivering an amount of aerosolized medicine for inspiration by a patient in response to the occurrence of appropriate delivery point or points in the patient's detected breath flow. The aerosol medication may be administered as one or more pulses having a pulse width, shape, and frequency that will maximize the respirable fraction of the aerosolized compound being administered. The delivery point or points may be predetermined or determined from a prior inspiratory flow for depositing the selected medication at one or more desired locations in the patient's airway. Determined delivery points are recursively lowered for each inspiratory flow that does not satisfy one of the predetermined and previously lowered threshold. Changes in the patient's breath flow patterns during the course of an aerosolized medication inspiration therapy program may be detected and used to adjust the controlled amount of medication to be delivered in a given administration and/or to inform the patient of the patient's condition or change in condition. The device also may contain a library of administration protocols or operating parameters for different medications and a means for identifying from the canister the medicinal contents of the canister for customizing operation of the apparatus.
95 Instrument for measuring and controlling flow rate and heating value JP8150190 1990-03-30 JPH03202743A 1991-09-04 PEETAA RIISU; PAURU NAUAA; BUORUFUGANKU FUUBAA
PURPOSE: To measure the flow rate or heating value of a fluid with sufficiently high accuracy by inputting a prescribed signal indicating the target value of a flow rate or heating value to be outputted and converting the signal into a signal indicating the presence/absence of a pulse, and then, driving a constricting device with the signal. CONSTITUTION: A prescribed signal which is proportional to the target value of a flow rate/heating value to be outputted is supplied to the input terminal E of a computer 14. The signal is converted into a signal indicting the presence/absence of a pulse by means of a converter 36. As the flow rate/heating value to be outputted becomes larger, individual pulses outputted from the converter 36 becomes longer and no-pulse periods become shorter. When, for example, a signal '0.8' is impressed upon the terminal E and a pulse signal is outputted from a clock generator 37, an H-level signal is generated at an output terminal 44. Consequently, the H-level pulse appears at an output terminal 19 and a motor 3 moves the constricting device 4 to an releasing (opening 5) position by controlling the device 4. When the input signal has a value between '0' and '1' in such a way, the device 4 is released for a different period in accordance with the length of the signal. COPYRIGHT: (C)1991,JPO
