Abstract: The present invention relates to a vacuum table for clothes, and more particularly, to a technology that imparts a vacuum suction function so that clothes can be fixed to a table top plate during manufacture and ironing of clothes, controls the foot plate for controlling vacuum suction so as to maintain the vacuum state without being pushed by an operator one by one, and thereby enhances convenience of an operator' work and enables adjustment to suit the operator's body by adjusting the height of the table top plate.

Abstract: The present invention relates to a sewing machine table. The sewing machine table with a rotatable operating foot pedal connected to a driving motor for a sewing machine, comprises: an upper frame provided with a top plate on which the sewing machine is installed, and a lower frame including: height adjustable supports provided at bottom ends of the upper frame for supporting the top plate and adjusting a height of the top plate; lower supports coupled to bottom ends of the height adjustable supports, and a first lower connecting plate coupled between the lower supports, the first lower connecting plate on which the operating foot pedal is installed. With this configuration, the sewing machine table is provided with an upper support coupled to a top plate and a cylinder inserted in the upper support and capable of adjusting a height, thereby enabling a height of the top plate to be adjusted according to a body size of an operator and increasing work efficiency.

Abstract: An actuator of an optical disk system and an apparatus producing a signal for driving the actuator, the actuator including a light source, with which information is recorded on or reproduced from an optical disk surface. In the actuator, an inner focusing coil and an outer focusing coil are installed near an inner boundary and an outer boundary, respectively, of the optical disk surface. A first signal wire is connected to a first port of the inner focusing coil and transmits an inner coil signal. A second signal wire is connected to a first port of the outer focusing coil and transmits an outer coil signal. A common signal wire is connected to a second port of the inner focusing coil and a second port of the outer focusing coil and transmits a common reference signal. Thus, a simple, inexpensive 8-wire actuator can be obtained.

Abstract: The present invention relates to a plasma display apparatus in which the noise of a data pulse can be reduced. In the transmission process of an image signal, a low voltage signal comprising a first signal and a second signal, preferably at least one of a LVDS, a BLVDS and a MLVDS is employed. This can reduce the influence of EMI noise on the image signal. Therefore, the present invention is advantageous in that the operational reliability of a plasma display apparatus can be enhanced and the picture quality of an image implemented can be prevented from being degraded. It is also possible to save power consumption. Furthermore, a data board is omitted and image data of a low voltage is directly supplied from a control board to a flexible substrate. Therefore, there are advantages in that the cost incurred by the data board can be saved and the manufacturing unit cost of a driving apparatus of a plasma display panel can be saved accordingly.
