Patent TW-427069-B (TW)
Title: Timing circuit that selectively triggers on a rising or falling input signal edge
Inventor: TERNULLO JR LUIGI
IPC: H03K5/00
Filed: 1999-03-29
Granted: 2001-03-21
Abstract: A timing circuit can be selectively configured to generate output pulses in response to either the falling edges or the rising edges of an input signal. The timing circuit includes a multiplexer, an output pulse width controller (OPWC), a gating circuit (GC) and a latch circuit. The OPWC includes a delay circuit that can be configured to provide a predetermined delay δ that can be larger than the pulse width of the input signal pulses. The multiplexer is connected to receive a first input signal and an inverted version of a second input signal. The first input signal is used in a rising edge triggered mode, whereas the second input signal is used in a falling edge triggered mode. The multiplexer receives a mode signal to selectively output one of the input signals to the GC. The GC is also connected to receive the output signal from the OPWC. The OPWC is configured in conjunction with the selected signal from the multiplexer, to cause the GC and the latch circuit to generate output pulses having a predetermined pulse width equal to δ, triggered by the rising edges of the selected signal. Because the second input signal is inverted, during the second mode the output pulses are in effect triggered by the falling edges of the second input signal.

Granted: 2002-04-21
Abstract: Process for the preparation of 3,5,5-trimethylcyclohexa-3-en-l-one (β-isophorone). The invention relates to a process for the preparation of the title compound by isomerisation of 3,5,5-trimethylcyclohexa-2-en-l-one (Α-isophorone) in the liquid phase in the presence of a salt-like or organometallic catalyst. Through the use of catalytic quantities of alkali-metal salts or alkaline-earth salts and of their organometallic compounds, and without addition of a further auxiliary substance, the space-time yield in the preparation of β-isophorone is successfully raised to a level suitable for industrial application by means of a reasonably-priced, generally available catalyst and at the same time a known per se process is distinctly improved. β-isophorone is particularly suitable as an intermediate product for the preparation of ketoisophorone.

Title: By-pass write drivers for high-performance data recording
Inventor: CONTRERAS JOHN T
IPC: G11B5/00
Filed: 1999-06-09
Granted: 2001-07-01
Abstract: A magnetic-head write-driver circuit includes a write-driver circuit and a by-pass driver circuit coupled in parallel to a signal path between the input and the output of the magnetic-head write-driver circuit. The write-driver circuit receives an input signal having transitions and outputs a first write signal related to the input signal. The by-pass driver circuit outputs an assist signal that is coupled to the first write signal to form an output write signal. The assist signal is related to transitions of the first write signal and assists in shortening reversal time of the transitions of a write signal by producing ""overshoots"" in the write signal at the time of the transitions. Additionally, the assist signal assists in charging and discharging a parasitic capacitance associated with an output of the magnetic-head write-driver circuit. The assist signal can add a current to, and/or enforce a voltage on, the first write signal to form the output write signal.

Abstract: The color cathode-ray tube comprises a shadow mask assembly having a shadow mask formed by integrally shaping a perforated part, a non-perforated part and a skirt part, and a support frame used to fit the skirt part to the inside of a frame-shaped body. For the skirt part of the shadow mask of the present invention, each of its long sides and each of its short sides are shaped into an inwardly recessed form; and for the frame-shaped body, each of its long sides and each of its short sides are shaped into a plane without welding dowel such that the skirt part can be welded and embedded into the frame-shaped body. Also, the outer end of the skirt part and the inner wall of the frame-shaped body are formed to contact with each other all around. Due to the above mentioned structure, the present invention can provide a color cathode-ray tube with a small magnetic resistance of the shadow mask assembly, and with no vibration of the shadow mask itself in applying external vibration. The present invention can also provide a color cathode-ray tube with the shadow mask which is easy to be manufactured and the perforated part of the shadow mask is not subject to be deformed.

Title: Prevention of forming abnormal capacitor by using offline edge-bead rinsing
Inventor: LIN GUO-CHI
IPC: H01L27/108
Filed: 1999-08-17
Granted: 2001-04-11
Abstract: This invention is about a method of assuring no capacitor peeling at wafer edge for the dynamic random access memory process. This method at least includes the followings. At first, a semiconductor substrate with a semiconductor structure is provided. Dielectric layer is formed to cover the whole surface of the semiconductor structure and then is pattern etched to define a contact window to expose one part of substrate. Silicon layer is deposited to cover dielectric layer and to fill up this contact window. Photoresist layer is coated on silicon layer. The first distance between wafer edge and inward of wafer edge is rinsed to strip the first part of photoresist layer. The second distance between wafer edge and inward of wafer edge is rinsed to strip the second part of photoresist layer. Therefore, the generation of abnormal capacitor in the following process can be avoided. Finally, photolithography process is performed onto photoresist layer to form photoresist mask. Silicon layer that is not covered by photoresist mask is etched to form lower electrode of capacitor. By removing the photoresist mask, the execution procedure of this invented method is completed.

Title: Manufacture method of high coercivity FePt-Si3N4 granular composite thin films
Inventor: GUO BO-CHENG
IPC: C23C14/06
Filed: 1999-10-19
Granted: 2001-05-01
Abstract: A method of producing high coercivity FePt--Si3 N4 granular composite thin films for high density magnetic recording media is invented. The method includes magnetron co-sputtering of FePt and Si3 N4 targets at controlled sputtering DC and RF power and rotating the substrate seat to form a (FePt)100-x-(Si3N4)x (x=0 to 50 vol.%) thin film. Two kinds of FePt targets can be used. One is the FePt alloy target. The other one is a composite target consisting of an iron disk overlaid with Pt pieces. The FePt composition in the thin film is controlled by the overlaid area of the Pt pieces. The substrate, using silicon wafer or quartz glass with naturally oxidized surface, is co-sputtered at room temperature. The as-deposited film has a granular structure with soft magnetic properties. The as-deposited film cannot be used as magnetic recording medium due to its low coercivity. After annealing at controlled conditions for a desirable temperature and time period in vacuum, the film also has granular structure but has high coercivity and its easily-magnetized direction is parallel to the film plane. It may be used as a high-density magnetic recording medium.
