A system and a method for manufacturing curved glass are disclosed. The system transfers a glass plate, which is molded, while the same is exposed to heat. To this end, a wire mesh-type jig is used. A glass plate is positioned between an upper plate heater, which can be lifted/lowered, and a lower plate heater and is then heated. In addition, while the glass plate, which has been heated to a working temperature, is adsorbed onto an upper mold unit, a high-temperature gas is ejected from below, thereby performing molding. Such a system and a method exhibit high energy efficiency, have simple processes, and therefore can produce a large amount of touch panel glass at economical costs.
Disclosed is a curved glass manufacturing apparatus. A process is performed while a lower mold part is transferred step-by-step by a conveyor in a heating furnace having a predetermined length. When the lower mold part is transferred to a working position after being preheated, a vacuum means is connected to the lower mold part to make a glass plate attracted to the upper surface of a core of the lower mold part. At the same time, an upper mold part moves downward to spray high-temperature gas onto the glass plate, thereby molding the glass plate. In addition, after the molding is completed, the conveyor transfers the lower mold part to a cooling position to cool the lower mold part.
An apparatus and a method for driving an icemaker for making ice cubes in a refrigerator. An ice-full state is sensed in such a way as to rotate an ejector and a cam gear in a reverse direction (opposite to an ice-ejecting direction), thereby preventing interference with the ice cubes present in the icemaker and thus enabling the ice-full state to be accurately sensed. A first torsion spring is mounted to an intermediate gear with a small rotation angle ratio to allow only a minimum amount of torque to be transferred to other components such as an ice-detecting lever, thereby increasing the durability of the components and providing a precise rotation force. The axial center of rotation of a second torsion spring is defined at a position that faces the other end (the revolving end) of the ice-detecting lever, to allow a minimum moment to be substantially constantly applied.
The present invention relates to a linear motion apparatus for a refrigerator, the part count and size of which are reduced, and in which an advancing/retreating rod can advance/retreat to/from an exact position without a separate micro-switch sensing the advancing/retreating position, and a motor can be prevented from being overloaded. The linear motion apparatus for a refrigerator according to the present invention comprises: a hollow case; an advancing/retreating rod which has a rack gear and which advances/retreats relative to the case; a motor accommodated in the case so as to generate power for powering the advancement/retreat of the advancing/retreating rod; a worm axially coupled to a rotating shaft of the motor; a first intermediate gear which is arranged at one side of the worm in the case, and the upper portion of which has a worm wheel meshing with the worm and a the lower portion of which has a lower spur gear; and a second intermediate gear which is arranged at the other side of the worm in the case, and the lower portion of which has a lower spur gear meshing with the lower spur gear of the first intermediate gear and the upper portion of which has an upper spur gear meshing with the rack gear.
The present invention relates to an apparatus and method for driving an icemaker for making ice cubes in a refrigerator or the like. More particularly, the present invention relates to an apparatus and method in which it is detected whether or not a maximum ice cube level has been reached while an ejector and a cam gear rotate in a reverse direction (opposite to an ice-discharging direction) so as to prevent interference with the ice cubes remaining inside the refrigerator, and thus accurately determine whether or not the maximum ice cube level has been reached. Further, the apparatus and method for driving an icemaker according to the present invention are configured such that a torsion spring is mounted on an intermediate gear having a small rotational angle ratio such that only a minimum amount of torque can be transmitted to other components, such as an ice-detecting lever, thus increasing the durability of components and providing precise rotational force. Further, the apparatus and the method for driving an icemaker according to the present invention are configured such that the axial center of the rotational direction of a second torsion spring, which enables the ice-detecting lever to elastically contact the cam surface of the cam gear, is arranged at the point facing the other side (revolving side) of the ice-detecting lever so as to enable the minimum moment to be regularly applied.
Provided is a driving device for an automatic ice-making machine, the driving device including: a cam gear that rotates a tray; and an operating lever that organically operates along a cam plane for an ice-cube quantity detecting arm formed at the cam gear and allows the ice-cube quantity detecting arm to rotate downward into an ice-cube storage bin, wherein a cam groove for the ice-cube quantity detecting arm is formed in the cam plane for the ice-cube quantity detecting arm of the cam gear and allows the operating level to descend so that the ice-cube quantity detecting arm rotates downward into the ice-cube storage bin, and a protrusion is formed between the cam plane for the ice-cube quantity detecting arm and the cam groove for the ice-cube quantity detecting arm and allows the operating lever to ascend so that the ice-cube quantity detecting arm that rotates downward into the ice-cube storage bin rotates upward.
The present invention relates to an apparatus for driving an ice maker for a refrigerator, which comprises: a case (100); a drive part (110) including a gearing part (104) with a magnet (M), and a motor (M) connected with the gearing part (104), the drive part being mounted in the case (100); and a housing (100b) for detachably mounting therein the case (100) containing the drive part (110); whereby the apparatus for driving the ice maker is assembled into a single module to reduce the time and speed of assembling thereof, thus improving the workability thereof. At the same time a low-voltage DC step motor is used to decrease the risks of fire and electric shock, thus enhancing safety. The magnet (M) is made to rotate about the central axis of the gearing part so as to generate a magnetic signal of rotation which may be detected and output. Hence the salability is maximized.
An antenna of a plasma processing apparatus includes first and second wiring groups that respectively are electrically coupled to different RF power source. The first wiring group is formed on an internal region and an intermediate region, and the first wiring group transfers a power of a first RF power source from the intermediate region to the internal region. The second wiring group is formed on the intermediate region and an outer region. The second wiring group receives a power of a second RF power source from the intermediate region, or alternatively from the outer region. The frequency of the second RF power applied to the second wiring group is lower than the frequency of the first RF power applied to the first wiring group, thereby reducing the plasma loss at the outer region.
