Title: Yarn feeder with weight-relieved shutoff means
Inventor: SCHMODDE HERMANN
IPC: D04B15/48
Filed: 2000-07-11
Granted: 2001-12-21
Abstract: One or several yarn feeler levers are provided in a yarn feeder, which rest on the yarn with a force which in the desired position of the lever, i.e., with a correct yarn run, is small. If the lever is pivoted out because the yarn tension is decreased or the yarn has broken, the force with which the lever rests on the yarn increases. This is achieved, for example, by a relief device which partially compensates the weight of the lever and provides a compensating force as a function of the pivot angle. The compensating force preferably decreases with an increase in the pivoting out of the lever.

Title: Disc playback status display
Inventor: GALLERY RICHARD DAVID
IPC: G11B27/30
Filed: 2000-08-01
Granted: 2002-03-11
Abstract: In an optical or magnetic disc audio system, during conventional play the audio is decoded and played from the disc (RDISC) under the direction of a presentation control (PC) and the subcodes indicating time on the disc, track number and so forth are generated. Depending on the system hardware, for some speeds and directions (other than normal play) it may not be possible to decode real subcodes from the disc, and an emulator module (EMU) is switched in at these times. The emulator (EMU) plays a virtual disc (VDISC) using a timer (TIM) and the table of the contents (TOC) from the real disc. Whilst the audio is not replayed, the track and time listing display (DISP) is kept up to date, with a typical update for each second of real disc play time. As an extension to this feature, the emulator module (EMU) periodically generates seek commands for the read head in relation to the real disc (RDISC) such that, when normal playback is resumed, there is minimal delay in locating the chosen audio.

Title: Process for preparing 2,6-dimethylphenol
Inventor: LI KUO-TSENG
IPC: C07C39/07
Filed: 2000-11-17
Granted: 2002-02-21
Abstract: There is provided a process for preparing 2,6-dimethylphenol from 2,4,6-trimethylphenol. The process is included with the formation of 3,5-dimethyl-4-hydroxybenzaldehyde by reacting 2,4,6-trimethylphenol with oxygen-containing gases at a temperature 20 to 200 DEG C in the presence of an iron-containing catalyst, and deformylation of the resulting benzaldehyde to 2,6-dimethylphenol with a copper-containing catalyst. The 2,4,6-trimethylphenol is reacted with oxygen-containing gases in the presence of an iron-containing catalyst, which has a higher 3,5-dimethyl-4-hydroxybenzaldehyde selectivity than the known copper-based catalysts, and an iron-containing catalyst is used to reduce the production of 2,6-dimethyl-p-benzoquinone. The inexpensive copper-containing catalyst is used to replace the customarily used precious metal catalysts for the effective deformylation of the 3,5-dimethyl-4-hydroxybenzaldehyde to 2,6-dimethylphenol. Therefore, the present invention can improve the economic benefit of the process for preparing 2,6-dimethylphenol from 2,4,6-trimethylphenol.

Title: LED driving circuit and optical transmitting module
Inventor: SAKURA SHIGEYUKI
IPC: H03K17/78
Filed: 2001-05-01
Granted: 2002-04-11
Abstract: The subject of the present invention is to have the capability of obtaining the following characteristics in an LED having a large internal capacitance, such as minimizing the increase in power consumption, shortening the transient response time, performing high-speed modulation, and obtaining output light almost free from pulse waveform distortion. The solving means is described in the following. An LED is an element in which when a voltage pulse Vd, which is applied to the intrinsic diode of an electrical equivalent model, reaches a dark point near the peak value, a current suddenly flows so as to obtain an optical output proportional to the forward current. A rectangular voltage pulse having a large-current driving ability at low output impedance, or a voltage pulse having two high levels where high voltage is adopted after a pulse is ascended and the pulse returns to the expected voltage after a constant period, is supplied to the serially connected LED load. In addition, the low level of the voltage pulse is set within a voltage range to apply DC bias where the required extinction ratio of an output signal from the LED can be maintained for the system requirement.

Title: Manufacturing method of copper dual damascene with selectively deposited barrier layer
Inventor: LIN JIUN-CHENG
IPC: H01L21/768
Filed: 2001-07-18
Granted: 2002-07-21
Abstract: The present invention relates to a method for manufacturing trench barrier layer of copper dual damascene, in which titanium nitride containing silicon [TiN(Si)] formed by adding silicon dopant into titanium nitride (TiN) is used as the barrier layer material of dual-damascene trench. Titanium nitride containing silicon [TiN(Si)] has the characteristic of selective deposition rate for different materials such that the chemical vapor phase deposition rate on the copper is lower than that on the other inter-metal dielectric layer. By appropriately controlling the deposition time, a barrier thin film of titanium nitride containing silicon with a certain thickness is formed on the dielectric layer of the trench sidewall in order to prevent the electric migration between the conducting copper wire and the dielectric layer. On the other hand, noticeable deposition of barrier layer is not formed on the copper during the same time. Therefore, the resistivity between the upper and the lower conducting wires is decreased such that the effect of too high RC time delay can be avoided and the speed performance of device can be improved.
