The present invention relates to a wired/wireless broadcasting distribution apparatus having a home broadcasting distribution function and a broadcasting channel formation/termination method using the same. A wired/wireless broadcasting distribution apparatus according the present invention receives HD-grade multi-channel ground wave/satellite/cable broadcasting signals, and converts the received broadcasting signals into an IEEE1394 Isochronous packet or converts the IEEE1394 Isochronous packet into a UWB wireless signal, and transmits the IEEE1394 Isochronous packet or the UWB wireless signal to a home client, thereby making it possible to distribute HD-grade multi-channel wired/wireless broadcasting signals requiring a transmission bandwidth of hundreds Mbps to home clients irrespective of place.

A method of synthesizing glycol diester by reacting a linear aliphatic carboxylic acid and a glycol monoester in the presence of a Lewis acid type catalyst is provided. In the method, after introducing the glycol monoester, the linear aliphatic carboxylic acid and the Lewis acid type catalyst into a reactor, the reaction occurs to produce reaction products and water in the reactor; an excess of the linear aliphatic carboxylic acid forms an azeotrope with water during the reaction to be sent to a condenser through a distillation column; the linear aliphatic carboxylic acid and water passed through the condenser are divided into an organic layer and an aqueous layer in an oil water separator; and the organic layer is returned to the distillation column through a material cycling line and water in the aqueous layer is removed through a water removal line. By utilizing reactive distillation technique, water produced during the reaction is rapidly removed, and thus the reaction time can be significantly reduced and the yield of the glycol diester can be maximized.

A micro gripper and a method for manufacturing the same are disclosed. The manufacturing method of the micro gripper supplies a fluid to a penetration hole of a gripper jaw, and discharges the fluid from opposite surfaces of the first and second structures of the micro gripper, thereby completely detaching the object attached on the opposite surfaces of the first and second structures by electrostatic force and removing the stiction. Furthermore, the present invention can grip the object more strongly by sucking the fluid from the penetration hole of the gripper jaw, when the first and second structures of the gripper jaw grip the object.
