Abstract: A laundry treatment apparatus includes: a drive unit including a rotating shaft, a drum configured to be rotated by the rotating shaft and receive laundry and including a cylindrical drum body and a rear cover, the rear cover defining a rear surface of the drum body and a rear cover through hole in an axial direction of the rotating shaft, and a shaft bracket that (i) is coupled to the rear cover and the rotating shaft, (ii) covers the rear cover through hole, (iii) is configured to transmit rotational force of the rotating shaft to the drum, and (iv) defines a shaft-coupling hole in the axial direction. The rotating shaft is inserted into the shaft-coupling hole, projected into an inside of the drum, and coupled to the shaft bracket by a rotating-shaft-fastening member.

Abstract: A laundry dryer includes: a cabinet, a drum rotatably disposed inside the cabinet and configured to receive hot air and steam, a steam unit disposed inside the cabinet and configured to generate the steam, a storage tank configured to detachably couple to an inside of the cabinet and receive water to be supplied to the steam unit, a tank accommodating the storage tank, and a floater placed inside the storage tank and configured to move in a vertical direction according to a volume of water in the storage tank. The floater includes a body portion having a first outer surface and a second outer surface, a third outer surface and a fourth outer surface, and a fifth outer surface and a sixth outer surface, where the first outer surface defines an upper surface of the floater and the second outer surface defines a lower surface of the floater.

Abstract: A laundry dryer includes: a cabinet defining an outer body of the laundry dryer, a drum that is rotatably disposed inside the cabinet and that is configured to receive hot air and steam, a steam unit that is disposed inside the cabinet and that is configured to generate the steam, a storage tank that is configured to detachably couple to an inside of the cabinet and that defines a storage space for receiving water to be supplied to the steam unit, and a tank housing that is disposed inside the cabinet and that is configured to accommodate the storage tank. An intake hole is defined at a front upper surface of the storage tank and provides, based on the storage tank being accommodated in the tank housing, an air flow path between the storage space and an external space of the storage tank.

Abstract: Disclosed herein is a manufacturing method of a spring pad interposed among a spring used in an automobile suspension system and an upper sheet and a lower sheet for supporting the spring, wherein the spring pad includes an insulator getting in contact with the spring to absorb shock and forming a body of the spring pad, and is manufactured through foam injection molding of the insulator to be lightweight.

Abstract: In an air conditioning system, a first controller converts the communication method of an external command inputted into the second controller and transmits the same to an air conditioner. Further, the first controller displays operating information of the air conditioner. Accordingly, the structure of the air conditioning system is simplified, and installation costs are reduced.

Abstract: Disclosed herein is a method for preparing oxytitanium phthalocyanine as a charge generating material. The method comprises the steps of mixing 30-100 wt % sulfuric acid and an oxytitanium phthalocyanine crude in a mixing ratio between 100:1 and 1:1, homogeneously grinding the mixture in a wet grinder filled with zirconia or glass beads as grinding media at ?20° C.˜60° C. for 0.1˜24 hours, and removing the grinding media from the ground mixture using a solvent. According to the method, oxytitanium phthalocyanine usable as a high-quality charge generating material can be prepared without the use of expensive and difficult-to-handle reactants, such as trifluoroacetic acid and pentafluoropropionic acid. Further disclosed is an oxytitanium phthalocyanine charge generating material prepared by the method.
