Publication number: 20010004065Abstract: A process of manufacturing a roll punch used for forming the partition walls on the rear panel of a PDP is disclosed. In the process of this invention, a forming roll is primarily coated with a mask on its external surface. The mask is, thereafter, partially removed from the forming roll, thus forming a plurality of regularly spaced mask-free parts on the forming roll. The forming roll is, thereafter, etched at the mask-free parts using ultrasonic waves within an etching tank, and so a desired roll punch having partition wall forming grooves is produced. This manufacturing process enlarges the width of the lands between the forming grooves of the roll punch, thus allowing an easy arrangement of address electrodes on the rear panel of a PDP. It is also possible to produce a desired highly precise roll punch by properly adjusting the intervals between the mask-free parts of the forming roll.Type: ApplicationFiled: December 7, 2000Publication date: June 21, 2001Inventors: Sang Jin Oh, Bong Hyang Kim, Deok Hwan Kim

Patent number: 6097018Abstract: A microwave oven includes a magnetron for generating electromagnetic wave energy, a waveguide for guiding and directing the electromagnetic wave energy into a cavity body defining a cooking chamber, and an antenna for radiating the electromagnetic wave energy generated by the magnetron into the waveguide. The waveguide includes a first opening for uniformly dispersing the electromagnetic wave energy into the cooking chamber, a second opening for uniformly dispersing the electromagnetic wave energy into the cooking chamber, and a short circuit for providing a short surface to the antenna. The first opening is formed on a portion of the waveguide which contacts the cavity body and extends along a longitudinal direction. The second opening is spaced away from and having a predetermined angle with respect to the first opening.Type: GrantFiled: January 7, 1999Date of Patent: August 1, 2000Assignee: LG Electronics Inc.Inventors: Hyun-Jung Kim, Hyung-Joo Kang, Han-Seok Kim, Sang-Jin Oh, Sang-Jin Kim
