Abstract: In a state where a shoulder member is in contact with a contact surface, a pin member is brought into contact with the contact surface to specify a pin movement amount, which is a distance from an initial position of the pin member to the contact surface, and specify a shoulder displacement amount, which is a displacement amount when the shoulder member is retreated as a result of the contact of the pin member. When both a first condition that the pin movement amount is included in a first range and a second condition that the shoulder displacement amount is included in a second range are satisfied, the pin member is retreated from the contact surface by a predetermined return amount, and furthermore, origin point alignment of the pin member and the shoulder member is performed on the basis of positions of the pin member and the shoulder member.

Abstract: According to a movement of the present disclosure, the prevention of the transmission of torque to a governor when excessive torque is generated and the prevention of the wasteful consumption of energy when the excessive torque is not generated are achieved. The movement includes a main spring which generates torque, a balance wheel, a gear train mechanism for transmitting the torque generated by the main spring to the balance wheel, and a spring seat for moving a second wheel, for example, of the gear train mechanism in a direction to reduce the transmission efficiency of the torque between the wheels of the gear train mechanism when the torque generated by the main spring is higher than a predetermined torque (Tmax).

Abstract: An optical rotation angle of linearly polarized light is modulated to obtain modulated light. The modulated light is passed through an inspection object containing an optically active substance. The optically active substance rotates an optical rotation angle of the modulated light. An intensity of light coming out of the inspection object is measured. Variation in the optical rotation angle of the modulated light is calculated based on the measured intensity and the angle to which the linearly polarized light is modulated. A concentration of the optically active substance in the pulsing component of the inspection object is calculated based on the variation in the optical rotation angle. Thus, concentration of glucose in the blood can be calculated without harming the patient.

Abstract: Equipment for melting a used injection needle includes a pair of movable contacts (2) and a fixed contact (3) between which electric voltage is applied. A short-circuit detector (4), determines when the movable contacts (2) and the fixed contact (3) are short-circuited by a used injection needle (9), and a timer (5) produces a signal during the period in which the short-circuit detector (4) produces a signal. An electromagnet drives the movable contacts (2) together to secure the used injection needle (9) to decrease the contact resistance between the movable contacts (2) and the used injection needle (9) and to allow a large electric current to flow in the used injection needle (9) in a stable manner.
