Abstract: Disclosed herein is a dental compound gun. A body unit has a gun shape. A compound material stick is inserted into the body unit through an insert hole formed in the body unit. A feeding unit transfers the compound material stick to an outlet. A melting unit heats the compound material stick and discharges melted compound material out of the body unit. A drive unit includes a trigger and a motor. A control unit controls power to be supplied to the motor. A support unit is coupled to a lower end of the body unit so that the body unit can be placed upright on a support surface. The control unit controls the motor in such a way that when the operation signal of the trigger is generated, the motor is forwardly rotated, and when the operation signal of the trigger is interrupted, the motor is reversely rotated.

Abstract: The invention relates to a wax dispenser for dental technology comprising: a wax reservoir in the shape of a hollow tube which contains a liquid wax therein; a nozzle which is disposed on the front end of the wax reservoir and which is in fluid communication with the wax reservoir; a heater which heats wax to keep wax contained in the wax reservoir in liquid state; an air-pressure supplier which increases the pressure in the wax reservoir by the introduction of air from the outside in a pressurization mode and decreases the pressure in the wax reservoir by the discharge of air to the outside in a depressurization mode; and a dispenser actuator comprising a wax passage which allows the wax reservoir to be in fluid communication with the nozzle, and a passage open/shut device arranged to open and shut the wax passage to discharge wax contained in the wax reservoir through the nozzle in the pressurization mode and to introduce wax from the outside to the wax reservoir through the nozzle in the depressurization m

Abstract: Disclosed herein is a sun visor for shielding sunlight. The sun visor includes a housing. A coupler is inserted at one end into the housing to be taken into or out of the housing, with a fitting member provided on the other end of the coupler. A mover is coupled to one end of the coupler in such a way as to be provided in the housing, with a stopping means provided on one or both sides of the mover. A shielding panel movably is coupled to the fitting member of the coupler to adjust an angle thereof, and shields a driver's eyes from sunlight. A mover guide is provided in the housing, and includes an interference face to control movement of the mover by interference with the stopping means, and a mover guideway to guide the movement of the mover in a space defined by the interference face.
