| 67 | A CONTINUOUS POSITIVE AIRWAY PRESSURE CONTROLLER | PCT/IE1999/000090 | 1999-09-03 | WO00013731A1 | 2000-03-16 | |
| A continuous positive airway pressure controller (1) for supplying a regulated oxygen/air mix to a respiratory circuit for supplying an enriched oxygen/air mix supply to a subject. The controller (1) comprises a main body member (2) having a main oxygen inlet port (4) for receiving oxygen from a pressurised source, and a main outlet port (5) through which the regulated oxygen/air mix is delivered to the respiratory circuit. A pressure regulator (10) located in an inlet gallery (7) regulates the pressure of oxygen in the controller (1) and supplies oxygen at the regulated pressure to a main gallery (11). A primary supply of oxygen to a main jet (14) is delivered through a primary flow control valve (25) from the main gallery (11). The primary oxygen supply is delivered by the main jet (14) through a venturi tube (16) where the primary oxygen supply is mixed with air for forming the oxygen/air mix drawn in through a venturi accommodating chamber (18). A secondary oxygen supply to the chamber (18) is provided from the main gallery (11) through a secondary flow control valve (28) for facilitating varying the ratio of oxygen to air of the oxygen/air mix. The flow rate of the oxygen/air mix from the main outlet port (5) is controlled by the pressure regulator (10) independently of the ratio of oxygen to air of the oxygen/air mix, which in turn is varied by the secondary flow control valve (28) independently of the flow rate of the oxygen/air mix. | ||||||

| 70 | Water level controller | JP30065090 | 1990-11-05 | JPH04171507A | 1992-06-18 | NAGAO TETSUYA; NANAO TERUAKI |
| PURPOSE: To attain the stable control of the water level without causing a hunting phenomenon by making the inflow subject to the characteristic which is inversely proportional to the water level when the water level of a distributing reservoir exceeds a target level and then setting the flow rate deviation obtained from the water level change and the area of the distributing reservoir at zero when the level of the reservoir approximates the target level respectively through the control of an inflow valve. CONSTITUTION: When the water level signal received from a water level indicator 2 is inputted to a water level/inflow setting means 10, the inflow is decided in response to a water level based on the prescribed control characteristic. That is, the maximum inflow is set and kept there until the water level approximates a target level. Then the set inflow inversely proportional to a water level change is decided when the water level approximates to the target level. This decided inflow is compared with the real inflow. When the water level approximates to a target level set optionally, the flow rate deviation caused by the water level change is obtained from the input value of the unit time, etc., and an inflow valve 4 is controlled so that the flow rate deviation is set at zero. Thus the water level is stably controlled regardless of the outflow. COPYRIGHT: (C)1992,JPO&Japio | ||||||

| PURPOSE: To keep a constant water level under stable control despite a small change of the water level by setting the opening amount of an inflow valve so as to be inversely proportional to the water level when the water level of a distributing reservoir approximates to a target level and controlling the opening amount of the inflow valve based on the difference between the set valve opening amount and the present opening amount. CONSTITUTION: An inflow valve 4 is provided together with a water level/valve opening amount setting means 7, a valve opening amount comparison means 8, and an inflow valve opening amount control means 9. When the water level signal received from a water level indicator 2 is inputted to the means 7, an inflow level opening amount is decided in response to the water level based on the prescribed control characteristic. That is, a constant inflow valve opening amount where the inflow exceeds the maximum outflow is kept until the water level approximates a target level. When the water level exceeds the target level, the inflow valve opening amount is set at a level inversely proportional to a level change set optionally. Then the valve opening amount is controlled based on the difference between the decided opening amount and the present one. Thus the water level is stably controlled despite a small change of the water level. COPYRIGHT: (C)1992,JPO&Japio | ||||||

| PURPOSE:To eliminate disadvantages of series and parallel operating systems respectively, by providing a Y register group arranged with n-set of m-bit registers in parallel and an S register group with the similar constitution. CONSTITUTION:A YM1 register 22 and an SM1 register 25 are connected to an adder 28 via connecting lines 29 and 32. The content of the YM1 register 22 and of the SM1 register 25 is summed at an adder 28, and the result of addition is stored in the register 25 via a connecting line 35. Similarly, the operation of YM2+SM2,-, YMn+SMn is executed in parallel. Taking a time required for the addition of one-bit as DELTAt', the time required for m-sets of integrating operation for n-bit with this constitution is mXDELTAt', and the operation time can be decreased to 1/n in comparison with a series operation. | ||||||

| PURPOSE: To realize the minaturization and high precision for the indicating mechanism with a simple constitution of the power balance type in which the servo system is formed with use of the nozzle, the flapper mechanism and the bellows each. CONSTITUTION: With application of input signal voltage Pin, input bellows 2 has the rotary motion counterclockwise with flexure 24 used as the intermediate vertical axis. Thus the gap is decreased between nozzle 5 and balanced beam 3, and the back pressure of the nozzle increases. Accordingly, the inner pressure increases for displacement output bellows 6 into which the nozzle back pressure is introduced, and bellows 6 has the clockwise rotary motion with flexure 64 used as the intermediate vertical axis. And pointer 8 indicates the pressure of that time. On the other hand, the right end of feedback spring 7 is shifted toward the right by the rotary motion of bellows 6 to apply the feedback force to beam 3. As a result, beam 3 stands still at the position where the balance is secured between the force caused by bellows 2 and the feedback force. COPYRIGHT: (C)1980,JPO&Japio | ||||||
