Disclosed is a display apparatus which is light and slim in its external appearance. The display apparatus includes a display panel which displays an image signal; a backlight unit which provides light to the display panel; a front member which includes a body whose central portion is open such that an image displayed on the display panel can be frontwardly exposed, and a support unit which supports the display panel and the backlight unit in the inner side of the body; and a rear member which is coupled to the front member and supports the back side of the backlight unit.

A heater of a bubble-jet type ink jet printhead enabling gray scale and manufacturing method thereof are provided. The heater includes two or more heating elements arranged concentrically around a nozzle. Each of the heating elements is formed in polygonal or annular shape and spaced apart by a different distance from the center of the nozzle. Each heating element is coupled to an electrode for applying heater drive power independently. Thus, the heater drive power is applied to each electrode selectively or in combination, thereby forming bubbles having different volumes.

A pickup actuator employed in an optical device for recording/reproducing information on/from an optical disc by using an optical device. The pickup actuator has a base member, a pair of yokes disposed at the base member and spaced from each other at a predetermined distance, a pair of magnets respectively attached to inner side surfaces of the yokes, a lens holder which is suspended by two pairs of wire springs so as to be moved toward directions of focusing and tracking in a space defined between the magnets, and on which an objective lens is mounted, a driving coil disposed at the lens holder, for driving the lens holder toward directions of focusing and tracking by electromagnetically interacting with the magnets, a pair of supporting plates disposed on the wire springs adjacent to opposite sides of one of the magnets, and a damping fluid applied between the pair of supporting plates and both opposite side portions of the one magnet, respectively for damping the vibration occurring at the lens holder when the lens holder is driven. Accordingly, when a vibration at the lens holder occurs, the vibration is directly damped by the damping fluid disposed between the one magnet and the wire springs which are supporting by the lens holder. Thus, an objective lens is allowed to reach a designated spot more rapidly. Accordingly, the pickup actuator can be employed in an optical device having the vibration of high intensity, such as in automobiles, etc.

Disclosed is a washing machine having a water guide for forming a vertical and a horizontal flow of wash water. The washing machine comprises a washing and dehydrating tub for receiving the wash water; a pulsator for forming a rotational water flow within the washing and dehydrating tub; and a water guide provided to an inner peripheral surface of the washing and dehydrating tub for defining a vertical passageway along the washing and dehydrating tub. While the wash water is rotated by the rotational movement of the pulsator, some of the water is guided along the passageway to the upper side of the washing and dehydrating tub where the wash water falls to the inner portion of the washing and dehydrating tub. The water guide has a main passageway and a pair of auxiliary passageways. A upper discharge port is formed at the upper portion of the main passageway, and the wash water is discharged through the upper discharge port. The auxiliary passageways have middle discharge ports for forming the side water stream. Thus, the wash water flows in to the inflow section of the water guide and then flows through the passageway upward. Some of the upwardly flowing wash water is discharged through the upper discharge port, while the other horizontally flows out from the middle discharge ports. Accordingly, during a washing/rinsing process, there are two streams of wash water, i.e., the vertically falling wash water which falls from the upper discharge port, and the horizontally flowing wash water which flows out from the middle discharge ports. The side water stream pushes the clothes to be washed to the center of the washing and dehydrating tub, while beating the clothes. Accordingly, the clothes to be washed are beaten by the vertical water stream and the horizontal water stream so that the washing/rinsing performance of the washing machine is much enhanced.

A clothes washing machine has a pulsator and a spurting apparatus for spurting washing water upwardly from the center of the pulsator, so as to disperse laundry gathered thereabove. The spurting apparatus has at least one guide duct and a spurt cap. The guide duct is fixed to an underside of the pulsator so as to rotate together with the pulsator. The washing water is introduced into a radially outer end of the guide duct and guided toward the center of the pulsator. The spurt cap disposed at the center of the pulsator guides the washing water upwardly.

Clothes washing machine having a water-ejecting pulsator

In a clothes washing machine, washing water is caused to spurt upwardly from the center of a pulsator, so as to disperse laundry gathered above the center of the pulsator. A washing water spurting apparatus includes guide ducts mounted on an underside of the pulsator. Each guide duct has an upper case, a lower case, and a first assembling mechanism for easily assembling and detaching the upper case and the lower case to and from each other. There is also a second assembling mechanism for assembling the guide duct to the underside of the pulsator so that the guide duct can rotate together with the pulsator.

A clothes washing machine has a washing water spurting apparatus for spurting washing water directly upwardly from the center of a pulsator. The washing water spurting apparatus has at least one guide duct and a spurt cap. The spurt cap has a canopy forming a spurt hole. The canopy has a core and an arcuate rim surrounding the core, between which the spurt hole is formed. The core has ribs extending from the core toward a cylindrical inner surface of the arcuate rim. Distal ends of the ribs are spaced a predetermined distance from the cylindrical inner surface. The ribs increase a spurting pressure of the washing water and prevent foreign materials from entering the guide duct downwardly through the spurt hole.
