Abstract: A vehicular air conditioning system includes: a refrigerant circulation line including first and second evaporators through which refrigerant can flow in a cooling mode, and first and second expansion valves configured to depressurize and expand the refrigerant introduced into each of the first and second evaporators; and refrigerant flow control part provided in front of the first evaporator and the first expansion valve and configured to control refrigerant flow. The first evaporator is used for cooling rear seat region of a passenger room and the refrigerant flow control part is configured to supply and block the refrigerant with respect to the first evaporator and the first expansion valve and is configured to block the refrigerant when the cooling governed by the first evaporator is controlled in a turn-off mode and supply the refrigerant to the first evaporator and the first expansion valve depending on the on/off condition of the cooling governed by the second evaporator.

Abstract: A polyimide precursor monomer having an E value of 2.0 or more calculated by Equation 1 is selected among polyimide raw materials. A polyimide includes a structural unit derived from the polyimide precursor monomer having the E value of 2.0 or more. Optical properties of a polyimide film formed from the polyimide can be improved, and the optical properties of a polyimide film can be predicted from the E value of the polyimide precursor monomer even before production of the polyimide film.

Abstract: Disclosed herein is a method of printing a nanostructure including: preparing a template substrate on which a pattern is formed; forming a replica pattern having an inverse phase of the pattern by coating a polymer thin film on an upper portion of the template substrate, adhering a thermal release tape to an upper portion of the polymer thin film, and separating the polymer thin film from the template substrate; forming a nanostructure by depositing a functional material on the replica pattern; and printing the nanostructure deposited on the replica pattern to a substrate by positioning the nanostructure on the substrate, applying heat and pressure to the nanostructure, and weakening an adhesive force between the thermal release tape and the replica pattern by the heat.

Abstract: Disclosed herein is a method of depositing a transition metal single-atom catalyst including preparing a carbon carrier, and depositing a transition metal single-atom catalyst on the carbon carrier, in which the carbon carrier is surface-treated by an oxidation process, and wherein the deposition is carried out by an arc plasma process.

Abstract: This invention relates to a hair braider and its auxiliary device, which are portable and braids three bunches of hair into a strand. The hair braider has a substantially figure ‘8’-configured cam track allowing three carriers to move along the cam track for a ‘8’ track motion. Three carriers combined detachably with three grabbing members accommodating three bunches of hair therein travels along the cam track as a couple of rotors rotate in opposite direction. While three hair grabbing member held on the holders of the carriers conduct the figure ‘8’ motion, three bunches of hair in three hair grabbing members are braided into one strand.

Abstract: The present invention provides an apparatus and method which contains a particular date preset by a user and several groups of particular information, each group relating to a pre-specified date difference between the preset date and current date, and automatically displays a group of information corresponding to current date difference. The apparatus according to the present invention comprises a nonvolatile memory for storing information corresponding to date differences, a timing unit for tracking current time and date, a control unit for calculating the date difference between the preset date and current date and reading out information depending upon the date difference from the memory, a ROM storing an execution program, a font ROM storing display fonts, a LCD control unit, a LCD panel, an audio signal generation unit, and a beeper.
