Title: Light-absorbing substance concentration in blood measuring, instrument and correction factor determining method for computing light-absorbing substance concentration in blood
Inventor: TAKEDA BOKU
IPC: A61B5/1459
Filed: 2001-04-19
Abstract: PROBLEM TO BE SOLVED: To measure an light-absorbing substance concentration in blood with an excellent precision without being affected even when an oxygen saturation concentration changes. SOLUTION: A 3 wavelength light source 1 casts a beam of a wavelength λ1=620 nm, and beams of two wavelengths λ2=870 nm and λ3=730 nm to a physiological body. In this case, the beam of the wavelength λ1 is absorbed by indigocarmine, oxidized hemoglobin and reduced hemoglobin. The beams of two wavelengths λ2 and λ3 are not absorbed by indigocarmine, and are absorbed by the oxidized hemoglobin and reduced hemoglobin.  A computer 6 calculates a ratio Φ12 for a variation portion of the absorbance of the wavelength λ1 and a variation portion of the absorbance of the wavelength λ2, and a ratio Φ32 for a variation portion of the absorbance of the wavelength λ3 and a variation portion of the absorbance of the wavelength λ2, based on the pulsation of the strengths I1, I2 and I3 of the beams which pass the physiological texture 2. A correction factor Φ12-α.ΔΦ32 is obtained by Φ12 and Φ32 and the correction factor α which is stored in advance. Then, an indigocarmine concentration in the blood is measured by the correction factor Φ12-α.ΔΦ32.

Title: Switching power circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 2001-04-23
Abstract: PROBLEM TO BE SOLVED: To facilitate design and manufacture by making the design margin small. SOLUTION: A driving winding of a self-excited oscillation driving circuit and a tertiary winding N3 are magnetic-coupled by a drive transformer with a compound resonant switching converter having a self-excited voltage resonant converter taken as a basic constitution, and a parallel resonance circuit for changing the impedance is formed by the tertiary winding N3, a condenser Cc, and an impedance control device Q2. Oscillation frequency (switching frequency) of the self-excited oscillation drive circuit is variably controlled, by making the impedance of the parallel resonant circuit variable, corresponding to a level change in a secondary DC output voltage.  It is thus possible to eliminate an orthogonal control transformer, by realizing constant voltage control with the compound control method for varying a continuity angle of the switching device and the switching frequency at the same time.
