IPC: F16J15/12
Filed: 1994-07-27
Abstract: PURPOSE: To eliminate inconveniences in spot welding work of empty wound metal hoop material in a spiral wound gasket. CONSTITUTION: A pair of disc sections 1, 1 which are made of a conductive material and have a chamfered conical face are overlapped with an insulation sheet material 2 therebetween and are integrated by a bolt 3. A disc-shaped electrode body A having a fitting groove 4 formed on an outer peripheral end face of a disc due to the conical face of the disc section 1 is used, and the fitting groove 4 is fitted in a corrugated projection section of a hoop material 5 which is empty wound around a winding plate 6. In the above-mentioned condition, voltage is applied to perform spot welding so that hoop materials are fixed at its welding fixing section 8.  Since the fitting groove 4 of the disc- shaped electrode body A is welded in a condition in which it is pressurized face-to-face for the corrugated projection section of the hoop material, the deformation due to wear does not occur in the electrode body. Consequently, correction and polishing work of the electrode body becomes unnecessary.

Filed: 1988-08-05
Abstract: PURPOSE:To prevent that a blood pressure value is determined to an erroneous value because of the movement of the body of a person to be measured by determining the blood pressure value of an organism from a previously obtained relation based on an impedance pulse wave signal. CONSTITUTION:Impedance to be generated between electrodes 30 and 32 changes correspondingly to blood quantity to increase or decrease synchronously with the pulsation of a heart, and this impedance pulse wave is closely related to the blood pressure value of an artery in the organism. For example, a fixed corresponding relation exists between either the maximum peak value and the minimum peak value of the impedance pulse wave or the rise inclination (or the fall inclination) of the impedance pulse wave and the actual blood pressure value of the organism. Therefore, the corresponding relation between the blood pressure value determined based on a pulse sound signal SO and a cuff pressure signal SP and the impedance indicated by an impedance pulse wave signal SI is obtained in a CPU24, and the blood pressure value of the organism can be obtained from the impedance between the electrodes 30 and 32 using this corresponding relation.
