Abstract: A semiconductor manufacturing equipment may include a process chamber for treating a substrate; a front-end module including a first transfer robot, wherein the first transfer robot may be configured to transport the substrate received in a container; a transfer chamber between the front-end module and the process chamber, wherein the transfer chamber may be configured to load or unload the substrate into or out of the process chamber; and a cassette capable of receiving a replaceable component capable of being used in the process chamber. The front-end module may include a seat plate configured to move in a sliding manner so as to retract or extend into or from the front-end module. The cassette may be configured to be loaded into the front-end module while the cassette is seated on the seat plate.

Abstract: A refrigerator may include a storage compartment, an inner door which comprises an opening having a size corresponding to a size of the storage compartment, a plurality of door guards, and an outer door which open and close the storage compartment, wherein the inner door comprises a control unit may control an internal environment of the storage compartment.

Abstract: A cathode for a lithium secondary battery includes a cathode current collector, and a cathode active material layer formed on the cathode current collector. The cathode active material layer includes cathode active material particles. The cathode active material particles include a lithium metal oxide particle containing nickel and having a mole fraction of cobalt of 0.02 or less among all elements except lithium and oxygen.

Abstract: The present invention provides a preparation method of a metal matrix composite. The method comprises the following steps of: 1) pulverizing a solid carbon material to a micrometer size; 2) plastic deforming a metal matrix powder and dispersing the pulverized nanometer-sized carbon material into the metal matrix powder during the plastic deformation; 3) integrating the metal/carbon nano-material composite powder obtained in step 2) by using a hot forming process; and 4) heat treating the integrated bulk material at a predetermined temperature to form a composite having a metal-carbon nanophase, a metal-carbon nanoband formed by growth of the metal-carbon nanophase, or a metal-carbon nano-network structure formed by self-coupling of the metal-carbon nanoband.

Abstract: The present invention discloses a heat exchanger fin having three rows of slit parts being arranged at the air inlet side and another three rows at the air outlet side relative to the centerline of heat transfer pipes 102, in order to reduce the ventilating resistance, prevent the growth of a boundary layer and reduce a dead zone on the downstream of the heat transfer pipes 102 to thus increase heat transfer performance. The outer slit parts 111 and 111′; and 116 and 116′ at the air inlet side and at the air outlet side are formed in pairs. The middle slit parts 112 and 112′ at the air inlet side are formed in pairs and the middle slit part 114 at the air outlet side is formed in a unit. The inner slit parts 113 and 114 at the air inlet side and at the air outlet side are also formed in a unit.

Abstract: The present invention relates to an outline font. The purpose lies in supplying a transforming and rendering method in the shape where the important form of the shape, such as the thickness of the stroke, will be maintained from the basic shape, and at the same time the whole size of the shape can be fitted into a given bounding box. The present invention supplies the transformation method of a handwriting font including searching for the medial axis of a given element, obtaining contact points by using maximal inscribed circles with the medial axis and points of the medial axis as a center, and applying the information about the medial axis points and the contact points in case of a transformation of the element in the transformation method of handwriting where a given element can be optionally transformed in sizes in order to achieve the purpose. The present invention enables the transformation of the shape.
