Title: Portable computer with cable guiding structure
Inventor: KIM HAE SU
IPC: G06F1/16
Filed: 1998-12-01
Abstract: PURPOSE: A portable computer with cable guiding structure is disclosed for easy installation of a cable that connects the base and panel, allows for safe cable movement when installed, prevents exposure of the cable, and does not restrict the panel's spread degree. CONSTITUTION: A portable computer with cable guiding structure's main features are its flexibility, easy installation capability, and safe and extended tilt movement of the panel. Notebook enables the cable, which is rolled around the hinge roll and extended from panel to the basis, to distinguish itself by its ability to insert itself to the inside of the base. The cable is sealed off from the outside by putting a cap on the part of the hinge roll and recess. The cable can be easily installed in a notebook, in which the cable can be combined or separated with the completely assembled base and panel. When the panel tilts, the cable absorbs the revolution force, and cable movement with the panel tilt is safely made. Because the exposed parts are capped, exposure of the cable is prevented and cable's rolling on a hinge enables the panel to tilt to more than 180 degrees.

IPC: G11C7/00
Filed: 1998-12-23
Abstract: PURPOSE: An input buffer for CKE is provided to minimize power dissipation according to the change in the potential level of CKE. CONSTITUTION: In the high state of a CKE, an NMOS transistor(MN12) is turned on while turning off an NMOS transistor(MN13).
