Abstract: The present invention relates to a method for increasing the productivity of 2?-fucosyllactose through various changes in culture medium composition and culturing on the basis of lactose, which is a substrate, wherein 2-fucosyllactose can be continuously produced in a high-yield at an optimum lactose concentration discovered by a culturing method of the present invention.

Abstract: Provided is a geothermal heat system having reduced heat source residual heat of a geothermal heat pump. The geothermal heat system includes a ground heat exchanger unit, a geothermal heat pump, and a residual heat storage tank. A portion of heat source residual heat remaining in the geothermal heat pump is transferred on a geothermal heat exchange medium passing through the geothermal heat pump so as to be stored in the residual heat storage tank. As the internal temperature of the residual heat storage tank gradually becomes the same as the temperature of the underground, the thermal load of the underground is removed. At least a portion of the heat source residual heat produced during provision of cooling/heating to the location of use is processed, thereby improving the operating efficiency of the geothermal heat system having reduced heat source residual heat of a geothermal heat pump.

Abstract: A crankshaft oil supply structure includes: an upper engine block having upper end saddles positioned at both ends thereof and an upper crank saddle positioned between the upper end saddles; a lower engine block formed with a plurality of lower crank saddle; an upper end bearing formed with an end bearing hole and mounted on each of the upper end saddles; an upper main bearing formed with a main bearing hole and mounted on the upper crank saddle; a lower bearing mounted on each lower crank saddle of the plurality of lower crank saddles; and a crankshaft formed with an end journal supported by the upper end bearing, a main bearing journal supported by the upper main bearing, and a crank pin journal. In particular, the main bearing hole is larger than the end bearing hole.

Abstract: A dual relief valve apparatus of a Balance Shaft and Oil Pump Module (BSM) of a vehicle engine may include the pump housing, and a primary relief valve and a secondary relief valve mounted inside the pump housing, wherein the primary relief valve and the secondary relief valve may be sequentially opened or closed, wherein the primary relief valve may be first opened to release a first oil by a first oil discharge pressure applied thereto and sequentially the secondary relief valve may be opened to release a second oil by a second oil discharge pressure applied thereto, the first oil discharge pressure being relatively smaller than the second oil discharge pressure.

Abstract: A method and device for displaying data are discussed. According to an embodiment, the display device includes a first display unit; a first display controller configured to control the first display unit, to receive at least one content to be displayed, to check if any data included in the content is to be displayed separately, and to transmit the data to a second display controller if the checking indicates that the data is to be displayed separately; at least one second display unit; and the second display controller configured to control the second display unit to display the data received from the first display controller, wherein the first display unit is configured to display the content excluding the data under control of the first display controller, and wherein the first display unit and the second display unit are physically separated display units.

Abstract: Disclosed are an image apparatus connected to an external device in which image contents are stored, and including a display unit on which the image contents are displayed, and an image contents searching method of the image apparatus, the image apparatus including: a pattern information storage unit which stores image pattern information corresponding to a keyword; and a controller which compares the image pattern information stored in the pattern information storage with the image contents in response to a searching request using the keyword, obtains an image pattern of the image contents corresponding to the image pattern information according to the keyword, and displays the certain image pattern on the display unit. A regular image pattern of the image contents is analyzed and compared to obtain and display a certain image pattern.

Abstract: An air conditioner which includes a plurality of indoor units to cool air of a plurality of rooms. Included is a plurality of branch refrigerant lines that each include a backflow prevention part provided at an end of the branch refrigerant line and/or a pulsation dampening part provided at an end of the branch refrigerant line, adjacent to the main refrigerant line. The air conditioner acts to prevent a liquid part of the refrigerant from flowing in a reverse direction into idle indoor heat exchangers. Furthermore, because a pressure pulsation of the refrigerant is dampened by the pulsation dampening part before the refrigerant is supplied into the indoor heat exchangers, the air conditioner reduces vibration, and, thus, noise from the indoor heat exchangers which is caused by the pressure pulsation of the refrigerant.

Abstract: Disclosed is a washing machine having a device (30) for filtering dirt in washing water. The device has a drawing pipe (31) connected to a tub (21) for accommodating laundry and water, a pump (33) for drawing the water in the tub into the drawing pipe, a cylinder (35) for receiving the water supplied from the drawing pipe, a rotating blade for generating a water-flow vortex in the cylinder, and a return pipe (37) for returning the water in which dirt has been filtered into the tub. The device can filter the dirt in the water effectively, and need not be cleaned frequently.

Abstract: A clothes washing machine includes a housing in which a wash tub is disposed. The housing includes a top cover in which an opening is disposed to enable clothes to be inserted into, or removed from the wash tub. The opening is closed by an openable door. The door is openable in response to the depressing of a foot pedal by a user. The foot pedal can be operably connected to the door by a wire arrangement such that the force for opening the door is provided by the user's foot. Alternatively, the foot pedal or a button could be connected to a motor which is connected to the door for opening the door when the foot pedal (or button) is depressed.

Abstract: A clothes washer includes a lid formed by a first member hinged to a housing of the clothes washer, and a second member hinged to the first member. The first and second members are folded together when the lid is opened, and are unfolded when the lid is closed. A motor-driven lid opening/closing mechanism is provided for opening and closing the lid. That mechanism includes a motor-driven rotary cam member mounted on the housing, and a following member fixed to the first member of the lid. During rotation in one direction, the cam member engages the following member to open the lid, and during rotation in the opposite direction, the cam member engages the following member to close the lid. When the lid is in the closed and open states, the cam member is disengaged from the following member to enable the lid to be manually opened and closed.
