    摘要: This invention relates to the modification of a moving magnet type of a direct current reading meter wherein by the addition of an electro-magnetic coil, the permanent magnet of the meter is influenced by the magnetic field of the coil with respect to the current flow to provide a reading to indicate full scale values of a much lower current value than that of the basic movement of the meter.

    摘要: To support a patient in an obstetric chair positioned for the convenience of the physician, the patient-receiving portion of the chair is mounted for changes in elevation and for different attitudes and includes channel-like thigh supports which confine the thighs of the patient and a recessed seat portion for supporting the buttocks of the patient. The backrest is vertical to the seat portion and has a central section extending slightly forward with two recessed portions and an overhanging back portion to further confine the patient between curved side portions. The channel-like thigh supports may be adjusted in angle with respect to each other and the seat portion is cut away to permit access to the perineum.
