摘要:
The following description provides a method for preparing electrodes for solar cells, substrates for the solar cell prepared using the same, and the solar cells. The method forms conductive paste on substrates by a printing method and a wet metal plating method, and forms a non-porous cell structure by directly plating a crystallized metal layer on the substrates via etching without using excessive non-crystallized conductive paste or plating the porous conductive paste with metal.

A low-dropout regulator with a single-transistor-control providing improved transient response and stability is disclosed. The single-transistor-control provides a dynamic resistance at the output of the regulator for minimizing undershoot and overshoot, and hence improves transient response. Since the single-control transistor reduces the output resistance of the regulator, the output pole is pushed to a sufficiently high frequency without affecting stability. Therefore, the limited choice of combinations of the output capacitance and its equivalent-series-resistance is substantially relaxed.

An optical sensor has at least one pixel that generates an output voltage that changes at a rate dependent on the light intensity incident on the pixel. The time for the pixel output voltage to change from a first predefined level to a second predefined level is measured, so as to produce an output indicative of the incident light intensity.

A semiconductor device may include a substrate and an insulating layer formed on the substrate. A multi-layer fin may be formed on the insulating layer and may include two semiconducting layers isolated by an insulating layer in vertical direction. A first MOS type device comprising a first source region, a first channel region and a first drain region is arranged on the first semiconducting layer in the multi-layer fin. A second MOS type device comprising a second source region, a second channel region and a second drain region is arranged on the second semiconducting layer in the multi-layer fin. A gate electrode is provided so as to be vertically adjacent to the first and second channel regions.

A method, system, and computer product uses a hashed static single assignment (SSA) form as a program representation and a medium for performing global scalar optimization. A compiler, after expressing the computer program in SSA form, can perform one or more static single assignment (SSA)-based, SSA-preserving global scalar optimization procedures on the SSA representation. Such a procedure modifies, (i.e., optimizes) the SSA representation of the program while preserving the utility of its embedded use-deprogram information for purposes of subsequent SSA-based, SSA-preserving global scalar optimizations. This saves the overhead expense of having to explicitly regenerate use-def program information for successive SSA-based, SSA-preserving global scalar optimizations.

A system for enhancing steam distribution in a thermal stimulation phase, and for reducing the production of particulate matter with hydrocarbon fluids in a production phase, has a base pipe with a limited number of spaced-apart holes. The spaced-apart holes are sized and located so that steam is uniformly distributed in the reservoir. A collar is disposed around each hole to deflect the steam into an annulus between the base pipe and a wire-wrap screen section to avoid erosion and deterioration of the wire-wrap screen, which is required in the production phase. Mobilized hydrocarbon fluids flow to the wire-wrap screen section, which acts to filter particulate matter so that the production of particulate matter with hydrocarbon fluid is limited. The open area in the base pipe is significantly reduced, as compared with conventional methods, so that at the design injection rates, the pressure drop through the spaced-apart holes is larger than the pressure drop along the base pipe. During hydrocarbon fluid production, the pressure drop from the reservoir to the spaced-apart holes is low due to the presence of the wire-wrap screens. The open area in the base pipe while significantly reduced at the design production rates, as compared with conventional methods, should not unduly limit production rates.

The present invention is an alternative lighting technology to form light emitting diode (LED) light tube. The tubular or circular LED tube is formed by transparent plastic and a metal heat sink that includes LEDs soldered onto a metal core printed circuit board with a special arrangement to achieve greater brightness than an equal distance arrangement. All LEDs are directly inserted into the metal core printed circuit board with a unique insulation coating to allow the LED anode and cathode to be inserted into the metal core printed circuit board and soldered on the opposite side of the metal core printed circuit board. It can connect one or more control units to control intensity.

A method for an allocation of stacked registers for Intel's Itanium® processor includes a three step process. Step I determines an intra-procedural stacked register usage by a program having a plurality of procedures. In step II, the disclosed method performs an inter-procedural analysis to assign quota of stacked register usage to every procedure. In step III, each procedure is allocated stacked register usage based on the quota assignments of step II.

A procedure which is a particular type of software pipelining is provided which increases the efficiency with which code is executed by reducing or eliminating stalls such as by filling delay slots. The process includes moving instructions in a loop from one loop iteration to another. The moving of instructions provides the scheduler with additional independent instructions in a given basic block so the scheduler has greater freedom to move instructions into unfilled delay slots. The procedure includes changing the entry point into the loop, thus effectively moving an instruction from near the top of the loop to near the bottom of the loop, while changing the iteration number of the moved instruction.
