    Abstract: Disclosed are a device and a method for generating ultrasonic scan image information, which can convert a rotatory motion of a motor into a linear reciprocating motion of an ultrasonic probe to allow the ultrasonic probe to scan a subject at high speed, and rapidly generate an accurate three-dimensional ultrasonic image by using a trigger signal. The device for generating ultrasonic scan image information disclosed herein converts a unidirectional rotatory motion of a driving motor into a linear reciprocating motion of a ultrasonic probe connected to the driving motor and two-dimensionally scans a subject by the linear motion of the probe and a vertical motion perpendicular to the linear motion so as to generate an image of the subject. The device may comprise: an ultrasonic irradiation/reception unit for irradiating a subject with ultrasonic waves through a probe and receiving a reflection signal of the irradiated ultrasonic waves through the probe; a signal conversion unit for receiving the reflection signal and converting the reflection signal into a digital image signal; a main control unit for receiving the digital image signal and generating ultrasonic image information about the subject; and a trigger control unit for generating a trigger signal on the basis of motion information of the probe, wherein the ultrasonic image information is generated in synchronization with the trigger signal.

    Abstract: Disclosed are a solenoid actuator and a multi-stage solenoid actuator for transmitting a constant force. The solenoid actuator includes a tubular solenoid, a power unit capable of applying current to the solenoid, and a magnetic pair member having two magnetic members providing magnetic fields formed such that respective first poles thereof face each other and respective second poles thereof different from the first poles are located at both distal ends, and extending through the tub of the solenoid. The multi-stage solenoid actuator includes a solenoid assembly where at least two tubular solenoids are regularly aligned such that inner spaces of the tubes of the solenoids are arranged in series, a power unit capable of individually applying current to each solenoid of the solenoid assembly, at least one magnetic pair moveable unit having two magnetic members providing magnetic fields formed such that respective first poles thereof face each other and respective second poles thereof different from the first poles are located at both distal ends, and extending through the tub of the solenoid assembly, and a controller for determining and controlling a solenoid to receive the current from the power unit depending on a position of the magnetic pair moveable unit.
