Abstract: Disclosed herein are a refrigerator includes a housing, a door rotatably installed at the housing using a hinge, and a door driving system to open or close the housing using the door. The door driving system includes a motor to output power to open or close the door, a sun gear linked with the motor, a planetary gear linked with the sun gear, and provided to be rotated about an axis thereof and to revolve, an internal gear linked with the planetary gear and configured to transfer power generated by the motor to the hinge, and a carrier configured to be rotated linked with the planetary gear and selectively support the planetary gear to be rotated about the axis thereof. When the planetary gear is rotated about the axis thereof, the power of the motor is transferred to the internal gear and thus the door is automatically opened or closed.

Abstract: A refrigerator includes a body and a drawer. The body includes a storage compartment. The drawer is insertable or withdrawable into or from the storage compartment. The refrigerator also includes a support configured to supports an item accommodated in the drawer. The refrigerator further includes a lifting device configured to lift the support with respect to the drawer. The lifting device includes a driving part that provides a driving force to the support, a wire that transfers the driving force of the driving part to the support, and at least one pulley which guides the wire.

Abstract: Provided is a vacuum insulator having both an excellent insulating performance and an excellent bending strength. A vacuum insulator (1) is configured by a sack-shaped enveloping member (3) and at least one sheet (7) including a plurality of inorganic fibers and includes a core member (5) enclosed in the enveloping member (3). The sheet (7) includes a plurality of bundled inorganic fibers (9) formed by bundling some inorganic fibers from among the plurality of inorganic fibers. At least a part of the bundled inorganic fibers (9) are in contact with each other.

Abstract: Provided herein is a door opening and closing apparatus capable of reducing torque of a motor required for removing an adhesive force between a door and a housing. The door opening and closing apparatus includes a motor configured to output power for opening and closing a door, a power transmission apparatus configured to transmit the power of the motor to a hinge by rotation of a plurality of driving gears, and an auxiliary apparatus configured to generate an auxiliary force for moving the door at a closing position toward an opening position, where the auxiliary force is generated at the auxiliary apparatus by the power of the motor before the power of the motor is transmitted to the hinge through the power transmission apparatus.

Abstract: An exhaust gas purifying apparatus which can reduce or prevent the shifting of a honeycomb catalyst member relative to a cushion member, even if hard vibrations are applied to the exhaust gas purifying apparatus, for example, during operation of a vehicle. In some embodiments, there can be no increase of the radial pressure of the cushion member applied to the honeycomb catalyst member. In some embodiments, an exhaust gas purifying apparatus can comprise a honeycomb catalyst member carrying metallic catalyst, wherein the member can be contained in a cylindrical container via a cushion member. The catalyst structural member can be formed of a sheet-like catalyst structure and can be manufactured by a wet paper-making method. The structural member can be secured to the cushion member by press-fitting the structural member into the cushion member.

Abstract: An air-conditioning apparatus capable of storing a surplus of refrigerating machine oil and returning a necessary amount of the refrigerating machine oil to a compressor as required. In an air-conditioning apparatus, a controller determines the amount of refrigerating machine oil that is present in a compressor by measuring power of the compressor and controls opening and closing of a solenoid valve on the basis of the measurement results.
