  • Patent number: 5755229
    Abstract: A pulse wave analysis device for analyzing the condition of a human body is disclosed. A cuff band is wrapped around the tip of the second finger of a subject's hand. When the operator depresses the beginning-of-measurement key, the finger tip is pressed at various pressures by means of an air pump and a pressure sensor. Pulse wave signals at different pressure values are automatically measured by an optical fingertip plethysmogram sensor. The signals are transmitted to a CPU through a BPF, an amplifier, and an ADC. The CPU performs FFT analyses on the signals and determines to which pattern from among the patterns stored in a ROM the pattern level of the pulse wave spectrum for a given pressure value is closest, and displays the result on a display unit as a test result indicating the viscoelasticity of the subject's peripheral circulation tissue.

  • Patent number: 5730137
    Abstract: A microcomputer performs a frequency analysis of pulse waves which are taken at regular time intervals from a patient through a pulse wave detection section. Then, if the amplitudes and phases of the spectra of the pulse waves fulfill some set conditions, either .alpha.-blocker or .beta.-blocker is given to the patient, and the patient's circulatory activity is maintained in a stable condition.

  • Patent number: 4679973
    Abstract: A pair of opposed spindleheads are rigidly mounted on a bed for holding a crankshaft to be machined between a pair of chucks on the ends of indexing spindles. One or more, preferably two, cutter assemblies are provided between the spindleheads for movement therebetween. Each cutter assembly includes a carriage slidable along a guideway on the bed and itself having slidably mounted thereon a slide which is reciprocable in a direction normal to the axis of the crankshaft. Mounted to the slide for rotation about an axis parallel to the axis of the crankshaft is a disklike tool holder carrying a annular, rotary cutting tool in an eccentric position thereon. The cutting tool has an annular row of internal cutting edges surrounding with clearance a desired part of the crankshaft to be machined.
