Title: Manufacture of semiconductor device
Inventor: IIMURA KATSUHIKO
IPC: H01L21/316
Filed: 1992-12-28
Abstract: PURPOSE:To form element formation regions of a first conductivity type well region and a second conductivity type well region, both having the same height, and also a resist pattern having an improved dimensional accuracy by subjecting the first conductivity type well region and the second conductivity type well region to the same selective oxidation. CONSTITUTION:A first conductivity type well region 2 is selectively formed on the surface of a semiconductor substrate 1, and a first selective oxide film 5 is formed on the first conductivity type well region 2. Then, after the first selective oxidation film 5 has been removed, a second selective oxidation film 8 is formed on a second conductivity type well region 6. After the second selective oxidation film 8 has been removed, an oxidation stopper film 14 is selectively formed at the area which will become an element formation region of a semiconductor device. Then, the semiconductor substrate 1 is selectively oxidized using the oxidation stopper film 14 as a mask, so that a third selective oxidation film 10 is formed at an element isolation region. Thereafter, for example, a gate oxide film 11 and gate electrodes, or the like, are formed.

Title: Mri device reducing gibbs artifact
IPC: G01R33/565
Filed: 1992-12-28
Abstract: PURPOSE: To reduce Gibbs artifact by performing asymmetrical sampling, complex conjugate, and filtering of an obtained signal. CONSTITUTION: An asymmetrical analog-digital converter 41 asymmetrically samples a signal received from a demodulator. The asymmetrically sampled signal is subjected to complex conjugate processing by a complex conjugate unit 42. A kayser filter 43 removes a Gibbs artifact from an output from the complex conjugate unit 42. A Fourier transform arithmetic unit 44 Fourier- transforms an output from the kayser filter 43. An image processing unit 46 synthesizes an output from the arithmetic unit 44 and displays it on the display. This can reduce the Gibbs artifact.

Title: Speaking system
Inventor: NAKAZONO KOICHIRO
IPC: H04M3/42
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To enable speaking in clear voice even when calls are concentrated in a specified area concerning a communication system utilizing a computer network. SOLUTION: When a server 1a on the side of a caller selectively calls a server 1b in the shortest distance from a terminal on the side of a callee as a server on the side of the callee, based on its on data throughput, the server 1b predicts a data throughput in the case of responding to this call. When this data throughput does not exceed its own data throughput, this call is responded to but when it exceeds the data throughput, an alarm showing such a state is issued to the server 1a and it is requested to change the server on the side of the callee to a server 1c. Therefore, even when calls are concentrated in the area where the server 1b is installed, speaking in clear voice is enabled without concentrating data processing to the server 1b.

IPC: G01J5/00
Filed: 1991-12-10
Abstract: PURPOSE:To measure the temperature of a body, to be measured, highly accurately by selecting the optimum emissivity, and decreasing the errors caused by the emissivity. CONSTITUTION:The rerationship between the ratio of the power of spectroscopic radiation energies E1, E2 and E3 at three different wavelength bands lambda1, lambda2 and lambda3 is determined. The spectroscopic radiation energies E1, E2 and E3 at the wavelength bands lambda1, lambda2 and lambda3 of a body W, whose temperature is to be measured, are actually measured and detected. The ratio of the power of the wavelengths lambda1, lambda2 and lambda3 of two sets of the spectroscopic radiation energies E1, E2 and E3 is obtained based on the detected spectroscopic radiation energies E1, E2 and E3. When two or more sets of emissivities epsilon3a, epsilon3b, epsilon3c and epsilon3d are computed, the values epsilon3a and epsilon3c and epsilon3b and epsilon3d of the emissivities of the individual sets are compared. The agreed emissivity epsilon3a or the emissivity epsilon3a having the minimum errors is selected. A temperature T of the body W, whose temperature is to be measured, is operated by using the finally selected emissivity epsilon3a.

Title: Production of optical fiber preform
Inventor: NARITA YOSHIHIRO
IPC: C03B37/014
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing an optical fiber preform capable of efficiently producing a fluorine added optical fiber preform which is uniform in a concentration distribution of a diametral direction. SOLUTION: Hydrofluoric acid or hydrogen fluoride reacts with glass to form silicon tetrafluoride and water. Then, if soot 1 is held in a hydrogen fluoride atmosphere, the hydrogen fluoride diffused from the surface into the inside of the soot 1 reacts with the glass of the soot and produces the silicon tetrafluoride. The concentration of the hydrogen fluoride is, therefore, kept always low with respect to the ambient atmosphere in the arbitrary position within the soot 1. Accordingly, the degradation in the diffusion rate by the saturation of the hydrogen fluoride into the soot 1 may be prevented and the concentration distribution in the diametral direction is made uniform.
