Patent TW-200533054-A (TW)
Title: Motor control circuit for supplying a controllable driving voltage
Inventor: CHEN CHI-YANG
Filed: 2004-03-25
Abstract: For applying a driving voltage to a motor, an H-bridge circuit is constructed by a first and a second linear unit and a first and a second switching unit. An error amplifier generates an error signal representative of a difference between the driving voltage detected by a voltage detecting circuit and a command voltage signal. A state control circuit synchronously controls the first and second switching units and a feedback circuit. Through the feedback circuit, the error signal is selectively applied to the first or second linear unit such that one is operated in a linear mode and the other is operated in a nonconductive mode, thereby controlling the driving voltage to become proportional to the command voltage signal. The state control circuit further controls a brake circuit for transforming the error signal into a brake signal to operate the first and second linear units simultaneously in a conductive mode.

Title: Method for forming single sided buried strap structure
Inventor: YANG SWEEHAN J H
IPC: H01L21/76
Filed: 2004-04-15
Abstract: A method for forming single sided buried strap structure is disclosed. The method includes providing a substrate having a pad oxide layer. A deep trench is formed in the substrate and a trench type capacitor is formed in the lower part of the deep trench. A conformal titanium nitride layer is formed to cover the substrate and the trench type capacitor. The etching selectivity of titanium nitride layer is different from the etching selectivity of the trench type capacitor and the pad oxide layer. A conformal amorphous silicon layer is formed to cover the titanium nitride layer. Afterwards, Boron implantation is performed at a predetermined angle to the conformal amorphous silicon layer. Therefore, a single side portion of the amorphous silicon layer within the deep trench is caused to have different etching selectivity. The single side area of the amorphous silicon layer is etched, as well as the titanium nitride layer and a portion of the capacitor thereunder are etched. At last, the single sided buried strap structure is formed.

Title: Catalytic converter for combustion engines
Inventor: VALDES-GONZALEZ JUAN
Filed: 2004-04-20
Abstract: The catalytic converter according to the invention fits to any combustion engine working with any fuel. The catalytic process takes places tanks to a particular combination of materials in a container through which the exhaust gases flow. The exhaust gases come from the ventilation systems of the combustion engine, flow freely through the container where they get in contact with the catalyzing materials and finally get back to combustion through the fresh air intake of the combustion engine. During the catalytic process, the long-chain hydrocarbons are divided into short-chain hydrocarbons and the configuration of electrons is changed. Both have a positive effect on the equality of the combustion process and on the smooth run of the engine, once the treated gases are recycled. In addition to reduction of emitted nitrogen oxides by minus 10-80%, of sooty particles by minus 35-90% and of toxic hydrocarbons and gases by minus 50-90%, the invention results in a increase of engine performance and in reduced noise production.

Abstract: A covering member having a valve encloses a flexible hose to form a double pipe. Gas supply pipe fittings are attached to respective ends of the double pipe to form a hermetic space between the flexible hose and covering member. The covering member also has a pressure-measuring device to which a decision unit equipped with an alarm device is connected. The same gas or liquid as the one flowing through the flexible hose is introduced to the hermetic space form the valve provided in the covering member, and sealed in the hermetic space by closing the valve. The pressure in the hermetic space is set so as to be higher than the pressure produced in the flexible hose when the gas or liquid is flowing. The pressure-measuring device measures the pressure in the hermetic space while the gas or liquid flows in the flexible hose, and the decision unit compares the measured value with a reference value. As a result, if the value measured by the pressure-measuring device is lower than the reference value, the decision unit decides that a breakage has occurred and then the alarm device activates an alarm.
