摘要:
A head drum assembly comprises a stationary drum, a rotary drum, and a self-compensating dynamic balancer. The stationary drum is fixed to a shaft, and the rotary drum is rotatably mounted to the shaft so that it faces the stationary drum. The rotary drum supports a magnetic head. The self-compensating dynamic balancer automatically compensates for any eccentricity between the rotational axis and the centroid of the rotary drum by using the centrifugal force of the rotary drum being rotated.

A head drum assembly of a tape recorder in which an inner race and an outer race of an upper bearing are press-fitted onto a shaft and a rotary drum, respectively, thereby applying a preload. A resilient body, such as a compressed coil spring, is disposed between a lower bearing disposed between the rotary drum and the shaft and a stationary drum. The resilient body upwardly presses the inner race of the lower bearing, thereby applying a preload. Accordingly, the head drum assembly of the tape recorder provides enhanced assembling efficiency and reduced manufacturing costs.

A method for setting a filter coefficient for a communication system, which adjusts a frequency bandwidth by setting a filter coefficient of a wireless communication system over a communication network, is provided. In the method, a wireless communication system that includes a controller having a filter coefficient database and a web server, and a Digital Signal Processing device requests a filter coefficient and attribute information related to a set target frequency bandwidth from a management terminal. The wireless communication system receives the filter coefficient and the attribute information from the management terminal and stores the filter coefficient and the attribute information in the filter coefficient database. The wireless communication system sets a frequency bandwidth of the digital signal processing device as a set target frequency bandwidth based on the stored filter coefficient and the attribute information.

A display apparatus includes a display panel for display an image, a camera module and a receiving container. The camera module includes a lens part mounted on a printed circuit board. The receiving container includes a main receiving space receiving the display panel and a sub receiving space extended from the main receiving space and receiving the camera module.
摘要:
Disclosed is a liquid crystal display apparatus in which a liquid crystal display module and cases are tightly combined. At least one protuberance formed on a top chassis of the liquid crystal display module combines at least one fixing portion formed on a portion of a rear case corresponding to the at least one protuberance. Also, a fixing protuberance formed on a portion of a front case is inserted into between the liquid crystal display module and the rear case, thereby preventing the liquid crystal display module from being moved. Therefore, the liquid crystal display module and the cases are tightly combined, and productivity of the liquid crystal display apparatus can increase by reducing the number of parts demanded for fabrication of the liquid crystal display module and the cases.
摘要:
A backlight assembly includes a receiving container and a light guiding plate. The light guiding plate includes a protrusion formed on a side portion facing a sidewall of the receiving container. When the light guiding plate drifts in the receiving container, the sidewall of the receiving container makes contact only with the protrusion extending from the light guiding plate, so that a contact area between the light guiding plate and the receiving container is reduced. Thus, a noise induced by friction between the light guiding plate and the receiving container may be prevented and a manufacturing yield thereof is enhanced.

An LCD apparatus includes a light guide plate; a lamp unit placed along at least one side of the light guide plate; and a lamp holder including a lamp supporting portion supporting opposite ends of the lamp unit, and a light guide plate supporting portion for supporting the light guide plate to prevent the light guide plate from contacting the lamp unit.
摘要:
A lower case for a display apparatus includes a receiving part and a sidewall part. The receiving part has a planar bottom plate extending in a first direction and a side portion substantially perpendicular to and extending from the bottom plate in a second direction normal to the bottom plate. The sidewall part is disposed along an edge of the bottom plate that forms a first receiving space with the bottom plate for receiving a backlight assembly having a light source assembly. The sidewall part further includes a first sidewall not adjacent to the light source unit, a second sidewall adjacent to the light source unit, and a third receiving space surrounding the first receiving space for receiving a wire.
