Abstract: A display device includes a display panel having flexibility, a storage connected to a first end of the display panel and accommodating the display panel so that the display panel is inserted and withdrawn, an extension part connected to a second end of the display panel, which is opposite to the first end of the display panel, and facing one side of the storage in a first direction, and a display driving integrated circuit which receives image data and a control signal from a host and provides a data signal to the display panel. The display driving integrated circuit includes a data processor which receives a smart size change signal from the host and sets a non-active area of the display panel based on the smart size change signal.

Abstract: An air injection system for an engine includes an exhaust flange formed in a cylinder head integrated with an exhaust manifold, wherein the exhaust manifold is coupled to the exhaust flange, an air injection nozzle provided on the cylinder head or the exhaust manifold, a valve configured to control air supplied to the air injection nozzle, and a controller configured to control the valve, wherein the controller is configured to control the valve and inject air through the air injection nozzle when an exhaust-gas temperature reaches a predetermined combustion temperature in an initial start stage of the engine.

Abstract: The present invention relates to a script management technology. Disclosed are approaches for managing scripts carried out in a script management server, which is connected to a user terminal and which manages script codes. Approaches comprise preparing a plurality of databases including a meta database and a plurality of script databases without necessarily separating physically the two types of databases; designating an active script database by providing the plurality of the original script lists to the user terminal; and storing identifiers of the user terminal and the designated active script database in the meta database, where the plurality of script databases are classified according to script version and each of them manages the original script code and user-specific script code, and the meta database manages a plurality of the original script lists related to the plurality of script databases and a list of user-specific scripts.

Abstract: Disclosed is a technology of managing a database. A database history management system includes at least one management object database server and a master management server for managing a history of the at least one management object database server. The database history management system includes at least one management object DB server and a master management server. The at least one management object database server establishing a management object database, and generating or updating a history database with respect to the management object database according to the history policy from the master management server. The master manager server manages a history policy with respect to the at least one management object database server, and accesses the at least one management object database server to remotely manage a history database with respect to a corresponding management object database.

Abstract: The present invention relates to a wind power generator. The power generator comprises a wing section including a hub, wings and a pitch angle control unit. The pitch angle control unit comprises a bearing and a first drive part, and the hub comprises an installation area used for a second drive part having a second drive gear to be engaged, in case an available area of the internal gear is damaged, with an area that is different from the available area of the internal gear. Accordingly, the maintenance and repair work can be facilitated and the maintenance and repair costs can be reduced.

Abstract: A device is proposed for producing high-frequency microwaves, having a cathode arrangement with heatable cathodes for emitting electrons, two grating arrangements for controlling and focusing the electrons flow and an anode for recaiving the electrons passing through the grating arrangements. The cathode arrangement and the first grating arrangement and also a blocking or choke element define an output cavity forming a resonance cavity and the anode and the second grating arrangement define an output cavity likeeise forming a resonance cavity. The cathode arrangement has a monuting for the cathode such that deformation of the cathode with reduction of the spacing between the heatable cathode and grating is avoided.

Abstract: The invention relates to a device (1) for producing high frequency microwaves comprising a cathode arrangement with heatable cathodes (15) for emitting electrons, two grid arrangements for controlling and focusing fluxes of electrons and an anode (3) for receiving the electrons flowing through the grid arrangements. The cathode arrangement and the first grid arrangement, in addition to a locking element or a throttle element (16), define an input cavity (12) forming a resonant cavity. The anode (3) and the second grid arrangement define an output cavity also forming a resonant cavity. Said cathode arrangement comprises a mounting for the cathode (15) such that a deformation of the cathode (15) is avoided by reducing the distance between the heatable cathode and the grids (18).

Abstract: A regenerative evaporative cooler, designed to improve the cooling efficiency of its regenerative evaporative cooling unit, is disclosed. In the cooler of this invention, the cooling unit consists of a dry channel and a wet channel arranged to closely come into contact with each other. The dry channel allows primary air to pass through, while the wet channel extracts a part of the primary air from the outlet end of the dry channel so as to form extracted air flowing in the wet channel in a direction opposite to the flowing direction of the primary air. A plurality of cooling fins are arranged in the dry and wet channels to allow the extracted air to come into direct contact with water so as to improve the water vaporization efficiency and the water vaporization area in the wet channel. A first blower fan sucks the primary air into the dry channel, while a second blower fan sucks a part of the primary air of the dry channel into the wet channel so as to form the extracted air.

Abstract: A method and apparatus for generating uniformly sized spherical ice particles. The apparatus comprises a water feed pump, a vacuum chamber connected to the water feed pump and having a water spray nozzle, boosters discharging the vapor from the vacuum chamber to maintain the inside of the vacuum chamber below a desired pressure and compressing it, a condenser for condensing the vapor being compressed by the boosters, and a vacuum pump for removing noncondensable gases from the condenser.
