Abstract: An air cleaner according to an embodiment of the present invention comprises a housing including a suction portion through which external air is suctioned and a discharge portion through which the suctioned air is discharged; a filter disposed between the suction portion and the discharge portion and configured to purify the suctioned air; a gas pump connected with the discharge portion and configured to rotate so as to discharge the air purified by the filter to the discharge portion and a controller configured to control a rotation direction of the gas pump, wherein the gas pump includes a rotor including a gas pump base disk disposed in and rotatably supported by the housing, a gas pump disk array in which segment disks having an open center area are disposed on the gas pump base disk to be spaced apart from each other, and a rotor magnet installed on the gas pump base disk and a stator including a stator coil disposed in the housing and installed to face the rotor magnet.

Abstract: Provided are: a vehicle cooling apparatus and a residential and office cooling apparatus, which are improved so as to prevent offensive odors and respiratory diseases by killing fungi and bacteria inside of a cooling part by means of hydrogen generated by electrolyzing the water condensed at the cooling part of the cooling apparatus; or a cooling apparatus and an air conditioning apparatus having a health-beneficial hydrogen generation device added thereto in which bacteria do not propagate since hydrogen is mixed and supplied to the interior air by means of a heat pump such that air quality is improved and the quality-improved air is supplied.

Abstract: In a hydrogen generation apparatus, water is electrolyzed by an electrolysis electrode part, and a porous ceramic catalyst may be combined with the oxygen generated at the time of electrolysis to prevent the generation of ozone. In addition, when the resistance value of water is measured, the change in resistance according to the kind of electrolyte dissolved in water and the concentration of the corresponding electrolyte is measured, and then, the applied voltage is varied depending on the measured resistance value, so that the water is electrolyzed in the optimal quantity according to the ingredient dissolved in the water, thereby preventing the generation of components harmful to the human body.

Abstract: A sales system includes a bar code scanner, a time stamp bar code adaptor, and a point of sale (POS) terminal. The time stamp bar code adaptor is configured for receiving the bar code scanned by the bar code scanner, extracting the country of origin, the manufacturer code, the product code, the date of production, the valid period, and the ID from the received bar code, and generating a sub code indicative of a ratio of a period, having elapsed from the date of production, to a point of sales, to the valid period. The POS terminal is configured for managing a product code table and a time stamp code table containing discount rate information, and calculating a discount price based on the elapsed period using the bar code and the sub code provided by the time stamp bar code adaptor.

Abstract: A surface traveling mobile apparatus which moves by an endless track belt installed to be wrapped around a case from end to end, traveling on a surface by the rotation of wheels driven by a power source is provided. The surface traveling mobile apparatus includes vacuum chambers installed to be attached to the sides of the wheels, a vacuum tube for connecting the vacuum chambers to each other, a vacuum pump formed in part of the vacuum tube, the vacuum pump for inhaling and exhausting air, and suction mechanisms installed along the endless track belt at predetermined intervals, valve driven by contacting the wheels, and vacuum attached to the surface by the vacuum pump inhaling and exhausting air. Also, a cleaning apparatus including a spray unit for spraying water or wash liquid to the surface when the surface traveling mobile apparatus moves, and a rotating brush for washing the surface using the sprayed liquid, are provided.

Abstract: A shoe corrector for correcting the shape of a shoe such that it completely fits a wearer's foot and making the interior space dry and clean is provided. The shoe corrector allows each individual's foot to be accustomed to shoes which are mass produced with standardized dimensions thus providing more comfort to the wearer. Furthermore, the shoe corrector prevents the shoe from deforming with long use.

Abstract: A sales method, a sales system, a bar code, and a bar code system, which vary a product's price according to the period elapsed from a manufacture date/hour to time of sale and predetermined data relating to a valid period by attaching a bar code, which includes the manufacture date/hour and predetermined data relating to a valid period, to the product or by printing the bar code, each having an expiration date, are provided. Thus, when customers select products whose discount rate is varied according to date and time elapsed from manufacture date/hour, problems relating to wasting and managing vicious stocks caused by last-in first-out purchase of products occurred during conventional distribution can be improved by encouraging first-in first-out purchase of products. The invention may be embodied in a general purpose digital computer by running a program from a computer readable medium, including but not limited to storage media such as magnetic storage media (e.g., ROM's, floppy disks, hard disks, etc.

Abstract: A method for diagnosing a vehicle state by connecting a vehicle equipped with an electronic control unit with a personal computer (PC) via a local area network (LAN) communication method, and then connecting the PC to a mechanic center on the Internet, is provided.

The shoe corrector allows each individual's foot to be accustomed to shoes which are mass produced with standardized dimensions thus providing more comfort to the wearer. Furthermore, the shoe corrector prevents the shoe from deforming with long use.

Abstract: A mosquito fumigator is provided. The mosquito fumigator includes a heating device, having a first substance and a second substance causing a chemical exothermic reaction separately disposed in a closed space of a case, configured such that heat generated by the reaction of the first and second substances is transferred to a radiation plate positioned on the case to heat a mosquito coil placed on the radiation plate, and an operating pin causing the reaction between the first and second substances inside the heating device. The mosquito fumigator heats and fumigates existing electric mosquito coils using heat generated by an exothermic reaction of chemical substances without a separate power supply, and is advantageously used outdoors.
