    摘要: A dental treatment apparatus with a root canal length measurement function comprising a cordless handpiece equipped with at least a cutting tool drive motor, a root canal length measurement circuit and a power supply battery, and a charger equipped with at least a charge circuit for charging the power supply battery. With this structure, the handpiece can be operated as desired without interference with any tube since no tube is necessary to connect the handpiece to a main control unit, thereby capable of providing an easy-to-use treatment apparatus. By charging the power supply battery for the handpiece using the charger, the battery can be used repeatedly.

    摘要: A pulse oximeter display device which displays oxygen saturation data is provided. The device comprises a multicolor display unit which displays oxygen saturation data in first and second colors. A display drive is coupled to the display unit, and a control unit is coupled to the display drive. Limits for oxygen saturation data are set by the control unit. The control unit further provides three signals to the display drive. The first signal is provided to continuously illuminate the display in the first color if the oxygen saturation data is within the limits. The second signal is provided to intermittently illuminate the display unit in the second color if the oxygen saturation data is not within the limits. The third signal is provided to continuously illuminate the display unit in the second color if the limits have not been set.

    摘要: In step s1, X-ray imaging is performed, and an image signal linear to the intensity of X-rays is stored in an image memory 7. Next, in step s2, the maximum from among image data is detected, and the maximum is set as reference value N0. In step s3, image data N is logarithmically converted in accordance with the following equation (a), and the converted data is stored in an image memory 7.d=.beta..multidot.log(N0/N) . . . (a)where d is image data after correction and has a logarithmic relationship to the X-ray intensity, and .beta. is a constant. Then, the image data logarithmically converted for density correction is displayed by a display unit 6 in step 4.
