Abstract:
A fuel cell system is disclosed. More specifically, the fuel cell system may include a stack that includes an electrical generation assembly of a fuel cell, an air supply unit that supplies air to a cathode of the fuel cell, a humidifier that humidifies exhaust air that is exhausted from the cathode and supply air that is supplied from the air supply unit, a hydrogen supply unit that supplies the anode of the fuel cell with hydrogen, and a water trap that traps condensate that is generated by the anode and exhausts it. In particular, the supply air is supplied to an upstream side of the humidifier and the condensate that is trapped in the water trap is supplied to an upstream side of the humidifier.
Abstract:
A charging cradle for mounting a portable terminal or a battery pack for the portable terminal, a multi-plug adapted to be mounted by being inserted into the charging cradle, hook holes formed in the charging cradle, and hooks adapted to be engaged with the hook holes, wherein the direction for inserting the multi-plug into the charging cradle and the direction for connecting the multi-plug to an external receptacle are perpendicular to each other, is provided, so that charging cradles adapted to be commonly used worldwide, and by localizing multi-plugs by countries or cities, i.e., by providing each country or city with multi-plugs adapted to be suitably used in such a country or a city, enable a user to use his or her charging device by only buying a multi-plug available in a country or a city where the user stays if it is desired.
Abstract:
Disclosed is a technique for localizing a sound source. In the technique, a sound pressure signal measured by microphones is acquired using a spherical microphone array sensor where the microphones are fixedly arranged on a surface of a spherical body. A sound pressure distribution on the surface of the spherical body is obtained by a controller from a sound pressure calculation formula for calculating a sound pressure at a certain location of a spherical surface using the sound pressure signal measured by the microphones as an input value. A location of the sound source is estimated from the obtained sound pressure distribution.
Abstract:
The present invention provides a preparing method of microcapsule containing unsaturated fatty acid comprising the steps of (a) preparing a first coating material by mixing and gelatinating one or more gums selected from the group consisting of xanthan gum, guar gum, and locusbean gum, with poly glycerin esters of fatty acid in sterilized water, adding unsaturated fatty acid to the solution, and homogenizing the solution; (b) preparing a second coating material by mixing and gelatinating starch or modified starch, gelatin or casein, and poly glycerin esters of fatty acid in sterilized water, adding the first coating material prepared in (a) to the solution, and homogenizing the solution; and (c) spraying the second coating material prepared in (b) in cold sterilized water; a microcapsule prepared by the method; and articles containing the microcapsule.The present microcapsule has effects of preventing the oxidation of unsaturated fatty acid and inhibiting offensive smell.
Abstract:
The present invention provides a multi-layer tablet comprising: an effervescent layer comprising hydrochlorothiazide or amlodipine or its salt as an active ingredient, a carbonate salt, and an organic acid; and a telmisartan-containing layer.
Abstract:
A charging device for a portable terminal is provided. The charging device includes a charging cradle for mounting the portable terminal or a battery pack for the portable terminal, a multi-plug adapted to be mounted by being inserted into the charging cradle, hook holes formed in the charging cradle, and hooks adapted to be engaged with the hook holes, wherein the direction for inserting the multi-plug into the charging cradle and the direction for connecting the multi-plug to an external receptacle are perpendicular to each other. In accordance with an exemplary embodiment of the present invention, by producing charging cradles adapted to be commonly used worldwide, and by localizing multi-plugs by countries or cities, i.e., by providing each country or city with multi-plugs adapted to be suitably used in such a country or a city, a user can use his or her charging device by only buying a multi-plug available in a country or a city where the user stays if it is desired.
Abstract:
Disclosed herein is a condenser connector for a vehicle, in which a condenser is installed at a position which is nearest or virtually nearest to a noise source, thus effectively eliminating or reducing noise. The condenser connector includes a housing having an insertion part. One end of a terminal is connected to a wire, and the other end thereof is fitted into and secured to one end of the insertion part. A holder is fitted into and secured to the other end of the insertion part. A condenser has a contact terminal which is in contact with the terminal, and is mounted to the holder.
Abstract:
Provided is an electronic device that includes an LTCC inductor including a first sheet disposed on a substrate and including a first conductive pattern, a second sheet disposed on the first sheet and including a second conductive pattern, and a via electrically connecting the first conductive pattern to the second conductive pattern, and a spacer disposed on a lower surface of the first sheet to provide an air gap between the substrate and the first sheet, wherein the first conductive pattern is exposed out of the lower surface of the first sheet.
Abstract:
Provided is a method for fabricating a device package. The method includes: preparing a substrate where respectively corresponding device structures and input and output pads are disposed on an active surface; preparing a carrier substrate where a metal lid corresponding to the device structure is disposed on one surface; and contacting the active surface of the substrate with the metal lid of the carrier substrate to cover and seal the device structure corresponding to the metal lid.
Abstract:
A defect analysis method includes storing, in a database, data indicative of defects and analog characteristics of corresponding defective bits in a database. A first defective area in a first wafer is found, and analog characteristics of defective bits in the first defective area are measured. The measured analog characteristics and the analog characteristics stored in the database are compared to locate a defect causing the first defective area.
