Abstract: An oil cooler includes a pair of spaced inlet/outlet boss portions; an inlet pipe and an outlet pipe coupled to the inlet/outlet boss portions, respectively; and tubes coupled to the inlet/outlet boss portions through both ends thereof to form an oil flow passage. The tubes are disposed in parallel and in a multi-stage arrangement. Each tube has a portion in fluid flow relationship with the neighboring tube at an area between the inlet and outlet pipes so oil can flow between them.

Abstract: An apparatus of controlling reception of various kinds of paper media includes a reception unit to allow the various kinds of paper media to be received, a pick-up unit to pick up the paper media from the reception unit one sheet by one sheet, a transport unit to transport the picked up paper media, a separation control sensing unit mounted on the transport unit to sense whether the paper media is passing through a predetermined transport path, a skew sensing unit mounted on the transport unit to sense skew of the paper media, and a control unit to operate the pick-up unit when the separation control sensing unit senses the paper media passing, and to suspend a forward operation of the transport unit and operate the transport unit backwards when the skew sensing unit senses the skew of the paper media.

Abstract: Disclosed is a bill recycle machine including a push plate exerting pressure on bills, which can apply separation pressure required for separating bills and also can be elevated upward and downward so as to prevent the push plate from being interfered with by a pickup roller when untaken bills is collected again.

Abstract: Disclosed is a bill recycle machine, in which a separation part for separating bills from each other and a push plate are installed at the same level as a bill receiving space, and an elevation plate is removed, so that a simple structure and small volume thereof can be achieve.

Abstract: The present invention provides a bill deposit and withdrawal apparatus comprising a shutter for opening and closing a bill-receiving space; a first plate for forming a front wall of the bill-receiving space and guiding transfer of a bill input into the bill-receiving space; a second plate spaced apart by a predetermined distance from the first plate to define the bill-receiving space; a third plate provided between the first and second plates to partition the bill-receiving space into two spaces; and a fourth plate provided below the bill-receiving space to transfer the bill stacked in the bill-receiving space toward a separator, whereby high reliability is achieved by avoiding jamming and the like that may occur when deposited bills are separated, bills to be withdrawn are stacked, bills rejected upon deposit of bills are stacked, or untaken bills are recovered.

Abstract: A stack type heat exchanger includes a plurality of unit frames stacked on one another, each unit frame including a tube made by combining a pair of plates and forming a path for refrigerant and upper and lower tanks disposed at upper and lower ends of the tube, a radiation fin provided between the stacked tubes, an inlet pipe and an outlet pipe provided at one side of the unit frames through which refrigerant enters and is exhausted, a first burr formed in the lower tank to protrude in a direction opposite to a direction in which the refrigerant flows, and a second burr formed in the upper tank to protrude in the same direction as the direction in which the refrigerant flows.

Abstract: Disclosed is an axial flow fan capable of achieving reduction of noise while having a high blowing efficiency compared to the power consumption of a motor adapted to drive the axial flow fan. The axial flow fan includes a hub, and a plurality of blades extending radially around the hub. Each blade has a sweep angle varying gradually from a backward angle at a root of the blade connected to the hub to a forward angle at a tip of the blade, while having a flow dispersion region having a plurality of regions where the sweep angle is alternately changed, at a region defined between a backward sweep angle region at the root of the blade and a forward sweep angle region at the tip of the blade. Each blade has a longitudinal cross section curved to have a wave structure between the root of the blade and the tip of the blade. The axial flow fan may further include a fan band connecting tips of the blades.

Abstract: A fan and shroud assembly includes a fan having a hub rotating around one shaft and a plurality of blades extending outwardly from the hub, a shroud encompassing the fan to adjust airflow by rotation of the fan, a guide ring portion located at a position where a predetermined gap exists between the shroud and a circumference connecting end tips of the blades so that the fan is supported by the shroud and rotates, and a plurality of swirl prevention units integrally formed with the guide ring portion to prevent a vortex from proceeding along the circumference in the predetermined gap, each swirl prevention unit having a shape in which the length of a circular arc passing through each of the swirl prevention units with respect to the center of the shroud decreases as the arc is closer to the center of the shroud.

Abstract: An air conditioner for vehicles is disclosed. This air conditioner feeds recirculation and fresh air in a separate air feeding or a mixed air feeding using a single intake duct and a single intake control door, thus improving its heating and defrosting efficiency during a heating mode operation, and preventing an undesired discharging of white fogging from the vents during a cooling mode operation by changing its air feeding mode from a recirculation air mode to a fresh air mode. This air conditioner also has a simple construction and is reduced in its production cost.

Abstract: A heat exchanger uses a refrigerant acting under a high pressure, such as carbon dioxide, as a refrigerant.

Abstract: In a fishing reel, a spool (200) can be easily and firmly assembled with a housing (100) and is not unexpectedly separated from the housing after assembled, and the rotation of the spool in one direction can be braked without moving a main shaft (110) relative to the housing. The fishing reel has a housing and a spool. A main shaft is fixed to a hub (130) of the housing. The spool has a winding drum (210) disposed at a center thereof. The winding drum contains a one-way clutch integrally fixed thereto. A sleeve surrounds a central portion of the main shaft with being in contact with the central portion. The sleeve is fitted in the one-way clutch and permitted to rotate in only one direction by the one-way clutch when the spool has been assembled with the housing. The spool can rotate in only one direction relative to the housing when the frictional force between the main shaft and the sleeve is adjusted to be maximum. The spool can rotate in either direction more freely as the frictional force is decreased.
