Title: Method for measuring blood volume and instrument therefor
Inventor: TAKANO HISATERU
IPC: A61B5/026
Filed: 1993-03-11
Abstract: PURPOSE:To make measurement with good accuracy by providing the instrument with auxiliary electrodes and correcting a change in impedance at the time of applying an AC voltage to the blood inflow side and outflow side of an artificial heart, measur ing the impedance and converting the impedance to the blood volume in a pump. CONSTITUTION:The pulsation flow type artificial heart 1 of an air driving type is driven by a driving device 5. A negative pressure is generated in an air chamber (a) and a diaphragm (b) is attracted, by which a valve (c) is opened and a valve (d) is closed so that the blood is sucked into a blood chamber (e). Positive pressure air is then sent from the driving device 5 into the air chamber (a) and the diaphragm (b) is pushed back, by which the valve (c) is closed and the valve (d) is opened so that the blood is pushed out of the blood chamber (e). These actions are repeated. An impedance measuring instrument 6 is connected with electrodes 2 and 3 applied with AC voltage and the change of the impedance is determined. The impedance measuring instrument 6 is connected between the electrodes 3 and 4 and the impedance by the blood itself is determined. The change in the impedance is corrected by a microcomputer 7 and is displayed 8. As a result, the blood flow rate is measured outside the body by the precise, inexpensive and small-sized device.

Title: Oxygen density detecting pilot burner
Inventor: KANEHARA NOBUYUKI
IPC: F23N5/24
Filed: 1985-03-14
Abstract: PURPOSE:To permit to detect oxygen density which natural gas is almost same as LP gas by a method wherein a flame hole part is formed out of metal of stainless series and a removable flame hole tip is provided on the tip end of the flame hole, while the flame hole tip is not used for the natural gas and it is provided for the LP gas. CONSTITUTION:The flame hole 1 of a pilot burner at an oxygen density detection is formed out of the metal of the stainless series. In case the oxygen density is decreased, the flame lifts up from the flame hole. An element 10 is hardly heated and electromotive force is decreased, therefore, a safety valve is closed and a gas circuit is intercepted. The flame hole 1 in case of the LP gas is exactly same as the flame hole 1 of the natural gas, however, the flame hole tip 6 formed out of the metal of the stainless series is provided so as to make small the flame hole area, so the spout seed of the LP gas is set so as to become faster than that of the natural gas. But the combustion velocity of the LP gas is faster than that of the natural gas, therefore, the lift-up may be effected by almost same oxygen density.

Abstract: PURPOSE:To improve accuracy by direct detection by relaxing a level fluctuation inside an apparatus by means of a filter plate and detecting level contact by means of a sensor. CONSTITUTION:Water enters/exits from a water introducing groove 2, and a water level is relaxed by a filter plate 3.
