Title: Erasable phase-change optical disc recording medium
Inventor: JIN JUNG-SHIUN
IPC: C22C28/00
Filed: 1998-12-24
Granted: 2001-10-21
Abstract: The present invention discloses an erasable phase-change optical disc recording layer and a phase-change recording material used as the optical disc recording layer. The optical disc recording layer comprises Te-Ge-Bi-Sb with a composition of 10 to 50 at.% of Te, 5 to 45 at.% of Ge, 10 to 55 at. % of Bi, and 2 to 12 at.% of Sb. The crystal state of the optical disc recording layer comprises at least one hexagonal crystal phase, in which the reflectance ratio of crystal to amorphous reflectance for one set of composition is larger than 20% in the whole visible light range. In another set of composition, the ratio of crystal to amorphous reflectance is 0 (according to the composition) for a specific wavelength in the laser wavelength of 500±50 nm. In the short wavelength range smaller than the range, the reflectance ratio is smaller than 0. That is the reflectance of the amorphous state is higher than that of the crystal state. Therefore, the present invention can provide an alternative choice for a system designer. Furthermore, the invented material can be used as a material for an ultra-high resolution layer material, and can further meet the design requirements of a dual-track recording or a dual-layer recording. Therefore, the present invention provides a phase change recording system designer with possibilities of more versatile designs.

Title: Image display device with element driving device for matrix drive of multiple active elements
Inventor: KAWASHIMA SHINGO
IPC: H05B44/00
Filed: 1999-03-18
Granted: 2002-02-21
Abstract: An image display device has multiple active elements arranged therein, such as an organic EL (electro-luminescence) element to form a matrix for driving these active elements. In the image display device, when a switching element is turned on with a control signal applied to a control electrode, a control current on a signal electrode is converted to a control voltage by a second transistor, held in a holding capacitor, and applied to a gate electrode of a first transistor. Thus, the signal electrode is driven by the control current, not by a control voltage, for controlling the operation of the active element. A driving voltage to be supplied to a power supply electrode is converted to the driving current and supplied to the active element.

Title: Data process system having an architecture for allocating data/address channel
Inventor: HOU JIAN-TSZ
IPC: G06F13/14
Filed: 1999-09-28
Granted: 2001-05-28
Abstract: The present invention relates to a data process system having an architecture for allocating data/address channel. It uses asynchronous data/address channels to replace the traditional synchronous data bus. Through several channels, the address/data is transmitted between the system controller and the devices connected to it. The switching box and the control logic in the system controller are used to determine the channel connection between devices. The required number of channels can be determined in accordance with the actual data flow requirement to increase the transmission bandwidth between two devices and, consequently, accomplish the optimal data transmission. Also, in order to save the turn-over time required for changing the transmission direction during data transmission and, thus, increase the data transmission efficiency, each channel can only transmit to one direction at each start.
