Granted: 2004-04-01
Abstract: The object of the present invention is to provide an optical disc device, which care reduce the instability of regeneration caused by the wiggling signal overlapped with the regenerated RF signal. The optical disc device according to the present invention is to irradiate the light beams onto the optical disc, wherein the optical disc uses the troughs on the optical disc recorded with the wiggling signals as the reference to confirm the tracks to form the pits on these tracks. The optical disc is recorded with information to detect the reflection light for generating the RF signals. The optical disc device includes the comparison means (72), wherein the comparison mechanism compares the RF signal with the threshold value to output the binary processing signal; a first bandpass filtering means (75), wherein the first bandpass filtering means abstracts the frequency band of the wiggling signal from the binary processing signal to obtain the components of wiggling signals; a first adding means (74), wherein the first adding means add the components of wiggling signal with the fixed reference value to form the threshold value, and provide to the comparison means. Thus, the components of wiggling signals overlapped with the RF signal will counteract the components of the wiggling signal of the threshold value, so as to reduce the occurrence of instability for regeneration during binary processing.

Title: Laser annealing method and semiconductor device fabricating method
Inventor: TANAKA KOICHIRO
IPC: H01L21/20
Filed: 2001-12-19
Granted: 2003-03-11
Abstract: When the second harmonic of a YAG laser is irradiated onto semiconductor films concentric-circle patterns are observed on some of the semiconductor films. This phenomenon is due to the non-uniformity of the properties of the semiconductor films. If such semiconductor films are used to fabricate TFTs, the electrical characteristics of the TFTs will be adversely influenced. A concentric-circle pattern is formed by the interference between a reflected beam 1 reflected at a surface of a semiconductor film and a reflected beam 2 reflected at the back surface of a substrate. If the reflected beam 1 and the reflected beam 2 do not overlap each other, such interference does not occur. For this reason, a laser beam is obliquely irradiated onto the semiconductor film to solve the interference. The properties of a crystalline silicon film formed by this method are uniform, and TFTs which are fabricated by using such crystalline silicon film have good electrical characteristics.

Title: Device for ensuring proper toe-heel installation of a detachable printer component
Inventor: STURGEON SCOTT D
IPC: B41J29/13
Filed: 2002-05-13
Granted: 2004-04-11
Abstract: A partial mounting portion cover (180) that extends above and partially over the front portion of a chamber (80) for operably receiving a detachable printer component (24, 24a, 24b) therein. The cover (180) includes a substantially planar top surface (182) positioned over the toe-end (140) of the detachable printer component (24, 24a, 24b) when the printer component (24, 24a, 24b) is fully installed on a mounting portion (50), such that the cover (180) extends over the printer component (24, 24a, 24b) only by an amount that precludes the cover (180) from interfering with a toe-heel installation process. Accordingly, so long as the installer mounts the toe-end (140) of the detachable printer component (24, 24a, 24b) first, the mounting portion cover (180) does not interfere with the installation. However, if an installer attempts to install the printer component (24, 24a, 24b) in another manner, the cover (180) blocks the toe-end (140) of the printer component (24, 24a, 24b) from entering the chamber (80), thereby alerting the installer of the improper installation method. In a preferred embodiment, the cover (180) is pivotally secured to the mounting portion (50), biased to a neutral position, and has a visually distinguishable color from the mounting portion (50).
