Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To stably and accurately estimate the center coordinates of an arc from data which makes reciprocating movement on the arc, during the noninvasive measurement of blood pressure which involves imparting vibration to a living body. SOLUTION: The arc center estimating part of a sphygmomanometer comprises a distance difference determining part 30, a data selecting part 31, a circle center calculating part 32, and a gravitational center calculating part 33. The distance difference determining part 30 determines the width of the distribution of data. The data selecting part 31 selects a plurality of sets of three data each, which have a spacing proportional to the data distribution width. The circle center calculating part 32 calculates the central point of a circle passing through three points in each set of data. The gravitational center calculating part 33 calculates the gravitational center of the central point. A phase angle is determined from the gravitational center to calculate blood pressure.  Blood pressure can be measured stably and accurately without being affected by the bias and variation of measurement data.

Title: Power source circuit
Inventor: YAMADA SATOSHI
IPC: H02H7/12
Filed: 1988-11-25
Abstract: PURPOSE:To reduce spike voltage when switching is made by rectifying the voltage having same polarity as one polarity of AC voltage induced in a fourth winding and detecting load current, and feeding output from the rectifier circuit to the power source for a control circuit if the detected load current is lower than a predetermined level. CONSTITUTION:Voltage of reverse polarity induced in a tertiary winding L3 decreases as ON interval of a transistor Q1 shortens and load RL current increases thus lowering source voltage to be fed to a control circuit 3. When the load current detected through a current detection resistor R0 lowers below a predetermined level, a voltage having same polarity as the voltage induced in a secondary winding L2 is induced in a fourth winding L4, then thus produced current is lapped over the current fed from a diode D4 and fed to the control circuit 3. Consequently, source voltage higher than a predetermined level is fed continuously to the control circuit 3. By such arrangement, spike voltage can be reduced when switching is made.

When a driving current 17 is allowed to flow to a drive coil 14, an ultrasonic converter 2 is oscillated by an angle theta so that one magnetic pole 8 on the movable side magnetized with N-polarity is opposed to a side part magnetic pole 12 magnetized with S-polarity and the other magnetic pole 9 on the movable side magnetized with S-polarity is opposed to a central magnetic pole 11 magnetized with N-polarity and, when the driving current 17 is allowed to flow to the drive coil 14 in the direction reverse to the above mentioned direction, contrarily, the ultrasonic converter 2 is oscillated so that the magnetic pole 9 on the movable side magnetized with S-polarity is opposed to a side part magnetic pole 13 and the central magnetic pole 11. By this method, the ultrasonic converter 12 can be subjected to oscillation motion.

Filed: 1988-11-28
Abstract: PURPOSE:To achieve a low cost and smaller size with a higher long-time reliability through a simplified mechanism section by a method wherein two luminous fluxes are created with a half mirror and one of mirrors reflecting the fluxes is inclined to receive an interference fringe generated with an image sensor. CONSTITUTION:Light incident from an incident slit 21 is made a parallel beam with a lens 22 to be turned to two beams with a half mirror 23, reflected by mirrors 14 and 15 separately to be converged by the mirror 23 again and enter an outgoing slit 27 through a lens 26. Here, the mirror 14 is tilted by theta  deg. and fixed so that an interference fringe is formed on an image sensor 18 correspond ing to an angle of the tilt. A light density pattern is converted into a time-series electrical signal by the sensor 18 and undergoes a Fourier transform with a spectral analyzer to measure a spectrum of an input light. This eliminates the need for operation of mirrors to change an optical path difference, thereby simplifying a mechanism section.
