Abstract:
The present invention relates to a metal-oxide-semiconductor field-effect transistor (MOSFET) with electrostatic-discharge (ESD) protection and a voltage-stabilizing capacitor, and a method for manufacturing the same and is applied to a chip, including a P-type substrate, a conductor layer, a first N-type doping region, a second N-type doping region, and an N-type well. The conductor layer is coupled to the ground; the first N-type doping region is coupled to the power supply; the second N-type doping region is coupled to a VDD pad (power-supply pad). Thereby, when the chip is not installed or not operating, the MOSFET can be used for ESD protection. When the chip is operating, the conductor layer, the first N-type doping region, the second N-type doing region, and the N-type well form a gate capacitor as a voltage-stabilizing capacitor between the power supply and the ground. Hence, the objective of fully utilization is achieved. In addition, the chip size is saved and thus the cost thereof is reduced.
Abstract:
A circuit for calibrating a data control signal comprises a time-delay compensation circuit and a voltage-control delay circuit. The time-delay compensation circuit receives two complementary signals and a direct current voltage which has two voltage cross points with the two complementary signals respectively, and outputs a control voltage according to a time difference between the two voltage cross points. The voltage-control delay circuit delays a data control signal for a predetermined time according to the control voltage, thereby eliminating signal skew between the data control signal and a data signal.
Abstract:
A new method is provided for the creation of an alignment mark. V-groove etching is applied whereby this anisotropic etch stops at the (1,1,1) crystal direction of the silicon of the substrate. The invention applies a wet etchant to the surface of monocrystalline silicon of the silicon substrate by using a solution containing a mixture of potassium hydroxide (KOH) or N2H4 or tetramethyl ammonium hydroxide (TMAH). This solution anisotropically etches the silicon substrate, forming grooves in the substrate having sidewalls that are sloped at an angle of about 54 degrees with the horizontal. The slope of the sidewalls is a function of the different etch rates of monocrystalline silicon along the different crystalline orientations. The surface of the substrate represents planes of the silicon, which etches faster than the sloped sidewalls that represent the plane. The KOH/N2H4/TMAH etch stops on the plane of the silicon substrate.
Abstract:
This invention discloses an integrated process of alkylation of olefins and regeneration of spent sulfuric acid. The alkylation of olefins may be replaced by nitration of toluene or by chlor-alkali process. The sulfuric acid is used as a catalyst or a absorbent, and the spent sulfuric acid is regenerated in situ and is recycled in the alkylation of olefins, nitration of toluene or chlor-alkali processes.
Abstract:
Using generated active intermediates or species simultaneously to remove water and organic compounds from the spent sulfuric acid catalyst of the alkylation of olefins and alkanes is disclosed in this invention. Over 90% water and 95% organic compounds of the spent catalyst can be removed by this invention under mild operating conditions, less than 20 atms and in the temperature range from -50.degree. to 250.degree. C. This invention provides a novel process instead of the traditional or commercial process by combustion and treatment of the spent catalyst at high temperature. It is significant to simplify comparing with the traditional process, and is a safe, simple, clean or pollutionless, and cheap one-stage process.
Abstract:
Sensors provisioned on a first device detect a movement of the first device corresponding to the first device changing position within an environment. Location information for the first device is updated based on the position change. A plurality of signals are detected, at the first device, from a second device in the environment, determine, and a distance between the first and second devices is determined based on each of the signals. From the signals, another change in position of the first device within the environment is determined and the location information updated for the first device. The movement is detected at the first device at an instance between two of the plurality of signals, and location information for the first device based on the first position change is updated prior to detection of the later of the two signals in the plurality of signals.

Abstract:
A controlling method and a controlling system for a handheld communication device are provided. In the present method, a tilting state of the handheld communication device is detected by using a G-sensor when a notice is activated. Then, whether the tilting state is changed from a face up state to a face down state is determined. The handheld communication device is controlled to perform a function when the tilting state is confirmed to be changed from the face up state to the face down state. Accordingly, the handheld communication device may be controlled to perform a function timely according to the positioned state of the device without going through complicated procedures, so as to provide a more intuitive and convenient way to control the handheld communication device.
