Title: Solar cell and solar cell unit
Inventor: FUJIMORI YUJI
IPC: H01L31/06
Filed: 2000-12-27
Granted: 2003-11-21
Abstract: A conventional dye-sensitized solar cell is a wet cell employing an electrolyte such as an iodine solution or the like, it is necessary to seal the solar cell with a sealing compound or the like in order to contain the iodine solution therein. Therefore, there are many problems in that, for example, leakage of electrolyte solution occurs when the sealing is broken. Furthermore, when only a flat-shaped titanium electrode is used, current and voltage of practically required levels can not be secured because the absorption area of solar rays is small. The solar cell of the present invention, employing a porous titanium dioxide semiconductor, is characterized in that the titanium dioxide semiconductor is held between a pair of electrodes so that the titanium dioxide semiconductor and at least one of the electrodes form a rectification barrier.

Title: Method for making a circuit board
Inventor: OTSUKA KANJI
IPC: H05K3/00
Filed: 2000-12-29
Granted: 2002-07-21
Abstract: A circuit board can minimize the increasing of resistance by the skin effect that is generated by signal line distribution and prevents the attenuation of high frequency signal. So the GHz high frequency digital signal transfer can be implemented. Two substrates 22, 23 with signal lines are fixed by an insulator in opposite and parallel way. The opposite surfaces of the substrates 22, 23 are smoothed, so the surface roughness is smaller than the thickness of the skin effect induced surface. Below one third is better and the resistance increased by skin effect is minimum.

Title: Semiconductor integrated circuit device and its manufacturing method
Inventor: OOTSUKA FUMIO
IPC: H01L21/8234
Filed: 2001-07-02
Granted: 2002-08-01
Abstract: Upon formation of a pocket ion region in a p channel type MISFET forming region (n type well) constituting SRAM by oblique ion injection, the p channel type MISFET forming region is disposed apart from a resist film formed over an n channel type MISFET forming region (p type well) within a distance, which is the product of the thickness H of the resist film and the tangent of an ion injection angle θ. Consequently, an impurity is not injected from one direction in spite of the injection from four directions, which makes it possible to suppress fluctuations of the impurity concentration in the pocket ion region.

Title: Multilayer mirror and method for making the same, and EUV optical system comprising the same, and EUV microlithography system comprising the same
Inventor: SHIRAISHI MASAYUKI
IPC: G02B5/08
Filed: 2001-10-19
Granted: 2003-02-01
Abstract: Multilayer mirrors are disclosed for use especially in ""Extreme Ultraviolet"" (""soft X-ray,"" or ""EUV"") optical systems. Each multilayer mirror includes a stack of alternating layers of a first material and a second material, respectively, to form an EUV-reflective surface. The first material has a refractive index substantially the same as a vacuum, and the second material has a refractive index that differs sufficiently from the refractive index of the first material to render the mirror reflective to EUV radiation. The wavefront profile of EUV light reflected from the surface is corrected by removing (""machining"" away) at least one surficial layer of the stack in selected region(s) of the surface of the stack. Machining can be performed such that machined regions have smooth tapered edges rather than abrupt edges. The stack can include first and second layer groups that allow the unit of machining to be very small, thereby improving the accuracy with which wavefront-aberration correction can be conducted. Also disclosed are various at-wavelength techniques for measuring reflected-wavelength profiles of the mirror. The mirror surface can include a cover layer of a durable material having high transparency and that reduces variations in reflectivity of the surface caused by machining the selected regions.

Title: Oversampling DAC with variable sampling rate
Inventor: HUANG JUI-CHENG
IPC: H03M3/00
Filed: 2001-12-06
Granted: 2003-01-11
Abstract: The present invention provides an oversampling digital/analog converter (D/A converter) with variable sampling rate, in which the D/AC is capable of processing input signals with different sampling frequencies. The oversampling D/A converter contains the followings: an expander, which increases the frequency of the input signal by a constant multiplication factor M to generate the oversampling signal; a digital low-pass filter, which filters the high frequency part of the oversampled signal and outputs the oversampled signal by using the first speed; a data buffer, which uses the first speed to reads the output signal of the low-pass filter; a modulator, which uses the second speed to read data of the data buffer, and modulates and converts it into a digital signal having fewer bits; a D/A converter, which converts the output signal of the modulator into the analog signal; and an analog low-pass filter, which filters out the high frequency part of the analog signal and generates the output signal. Therefore, because the modulator reads data with the same speed, the oversampling D/C converter can assure that noise dose not exist in low-frequency range regardless of the sampling frequency of the input signal.

Abstract: The invention is to provide a system and method for effectively transferring a data file from a first computer to a second computer, and in particular, the first computer is incompatible to the second computer. First, according to a predetermined reference file, the data types and data formats associated with the data file and recorded in a description file are automatically parsed to generate a metadata. The predetermined reference file defines rules of various data types and data formats translated between the first computer and the second computer. A manager then selectively alters, adds, deletes, divides or combines the data items, data types and data formats recorded in the metadata to generate a modified metadata. Finally, according to the modified metadata, the data of the data file are automatically transferred from the first computer to the second computer. Thereby, the data in a legacy computer can be efficiently transferred to a current computer, for example, data transferred form an IBM main frame to a Microsoft NT platform. The method of the invention can reduce transferring time and cost to benefit following applications.

Title: System and method for controlling line driver power in a shared digital subscriber line modem
Inventor: DAVIS GORDON TAYLOR
IPC: H04Q3/42
Filed: 2002-03-18
Granted: 2004-01-01
Abstract: A shared digital subscriber line modem achieves reduced total power consumption and data security by generating and transmitting a physical data frame which includes a control channel and a data field to only the connected client modem associated with the intended recipient. A second physical frame which does not include the data field is generated and transmitted to all of the other connected client modems. This method results in a reduction in the power required and provides improved data security by preventing data access to non-addressed client modems.
