Abstract: A dialysis system includes a dialysis apparatus, a measurement apparatus, and a control apparatus. The dialysis apparatus performs hemodialysis on a dialysis subject. The measurement apparatus measures a cerebral regional oxygen saturation of the dialysis subject. The control apparatus adjusts a hemodialysis operating condition by the dialysis apparatus so as to suppress decrease in the cerebral rSO2 based on the cerebral rSO2 of the dialysis subject measured by the measurement apparatus during operation of the hemodialysis by the dialysis apparatus.

Abstract: The present device is equipped with a measurement site holder 3 that is constructed using a negative impression of the measurement site 10. As a result, variation in the measured values caused by the non-uniform distribution of components in the measurement site 10 is reduced, so that variation in the measured values caused by variations in the light path length accompanying variations in the shape of the measurement site 10, and by variations in blood flow or the like that accompany differences in the contact pressure, can be reduced. Since living-body information and measurement parameters for the patient are recorded on a recording medium 11 mounted on a measurement site holder 3 for the exclusive use of the individual patient, the erroneous acquisition of living-body information for individual patients can be prevented, and reproducible measurements can be performed.

Abstract: A printed circuit board is supported at its peripheral portion and is moved and positioned by a drive mechanism. During the drilling of a hole in the circuit board, the thrust of the drill acting upon the circuit board is born by a sliding contact surface on a stand disposed on the side of the board opposite the drill. Ultrasonic vibration is applied to the printed circuit board via the stand during the drilling operation to prevent the occurrence of expoxy smearing.

Abstract: A machine tool with an automatic tool changer having a tool storage magazine accommodating tools having the same shank configuration as that of the first shank, tools having the same configuration as that of the second shank, and a tool adaptor which has the same configuration as the larger of the first shank or second shank and which incorporate the smaller shank sections of the tools of the first shank or second shank configuration.
