Title: Mri and mr imaging method
Inventor: MIYAZAKI MITSUE
IPC: G01R33/54
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To raise a signal value to keep S/N good and to secure information in a variety of traveling directions for enhanced depicting capability, when imaging a tissue or blood flow with which T2 time is as short as 100 to 200 ms. SOLUTION: An MRI converts an echo signal into an image through Fourier transform. The MRI includes a scan means which collects plural sets of MR original data by scanning the same part to be imaged of the subject of examination plural times while changing encoding direction and a generation means which generates one set of image data based on the plural sets of MR original data. The generation means includes, e.g. a means reconfiguring the plural sets of MR original data into actual space image data for each frame and a means by which the image data reconfigured for the plurality of frames are synthesized into image data for one frame. This synthesis is, e.g. addition process or maximum value projection process.

Title: Additional signal multiplexer and additional signal separator
Inventor: YASUKI SEIJIROU
IPC: H04N7/015
Filed: 1989-06-07
Abstract: PURPOSE:To expand a multiplex region of an additional signal by repeating a main signal with respect to a field and repeating an additional signal for each field where phase is inverted at each field and multiplexing both the signals. CONSTITUTION:An in-frame mean signal obtained through a low pass filter in a time direction comprising a field memory 12 and an adder circuit 14 is used as a main signal M. Then the main signal M is formed as field repetition signal and the additional signal is formed to be field repetition signal whose phase is inverted for each field, then the additional signal is superimposed even to a region from the 7th line to 19th line on both upper and lower extremes on the screen in which only the main signal M has been superimposed in a conventional system. Thus, the multiplex region of the additional signal is expanded.

Title: Method for liquid-phase epitaxial growth
Inventor: KAWABATA TOSHIHARU
IPC: C30B19/00
Filed: 1982-08-20
Abstract: PURPOSE:To achieve the growth of an n type epitaxial layer having high crystallinity in the preparation of an n type semiconductor using a liquid-phase epitaxial growth method, by setting the concentration of the donor impurity for doping at a level above the concentration of the residual acceptor. CONSTITUTION:An n type GaP substrate doped with S as a donor impurity at 980 deg.C is made to contact with a GaP solution doped with Te as a donor impurity at the same concentration as that of S. The system is heated for >=10min to increase the concentration of the impurities at the interface of both components, and cooled slowly to effect the epitaxial growth of a GaP crystal. The growth of the n type epitaxial layer begins before the S diffused from the substrate into the solution is separated far from the n type GaP substrate, and consequently, the donor concentration in the n type epitaxial layer becomes high at the initiation of growth, and the formation of p type inversion layer can be prevented. An n type GaP epitaxial layer having low donor concentration and excellent crystallinity can be prepared by this process.

Title: Method for detecting partial discharge of power cable connection part
Inventor: NISHIKAWA SATORU
IPC: G08C23/00
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To make it unnecessary to independently prepare a data transmission system and to make it possible to detect economical partial discharge by detecting the partial discharge of a power cable connection part by using an optical cable built in a power cable and transmitting measured data by using an optical fiber. SOLUTION: A detection impedance part 6 for detecting partial discharge is connected between a pair of detection electrodes 4a, 4b. A heat exchange system 7 amplifies an electric signal detected by the impedance part 6 and impresses voltage to a heater to convert the voltage into heat 8. A temperature measuring optical fiber core 5 built in a power cable line 1 is heated by the converted heat 8. Ramon scattered light is generated in the optical fiber by pulse light made incident from the end part of the core 5 to detect a partial discharge signal. Since the partial discharge information is added to the core 5, it is unnecessary to independently prepare a partial discharge data transmission system.

Title: Mixed flow compressor
Inventor: NISHIDA HIDEO
IPC: F04D29/44
Filed: 1989-06-09
Abstract: PURPOSE:To enhance the performance of compressors by forming a guide channel which introduces liquid in a chamber formed by depressing the surface of a channel on the side of a side plate at the bend of a diffuser inlet, into a suction pipe. CONSTITUTION:After a flow is sucked into a mixed flow impeller 1 from a suction pipe 8 and boosted, it is slowed down by a diffuser 6 and led into a casing 7. Since the curvature of the meridional channel of the mixed flow impeller 1 is small, the flow becomes nearly uniform in the cross direction at the outlet of the impeller. The flow came out from the impeller 1 and entered the diffuser 6 is drawn nearer toward the side of a center plate due to the small curvature radius of the bend at the diffuser 6 inlet, and the flow velocity on the side plate side tends to become small. However, a chamber 9 is located at the inlet part of the diffuser 6, and the fluid inside the high pressurized chamber 9 is flown into a suction pipe 8 through a guide channel 10, so that the flow with a low flow velocity on the side plate side is sucked into the chamber 9. As a consequence, the flow at the diffuser's bend terminating part 6b becomes uniform in the cross direction to substantially improve the diffuser performance, i.e., the performance of the mixed flow compressor.

Title: Liquid fuel combustion apparatus
Inventor: IWASAKI NOBUHIRO
IPC: F23D11/02
Filed: 1992-06-08
Abstract: PURPOSE:To prevent combustion from becoming impossible within a short period of time when deteriorated fuel is fed. CONSTITUTION:Tar is a residue produced during vaporization of liquid fuel and absorbed by a filter 35 provided on a vaporization stabilizer member 3 in a vaporizing chamber 2 via a clearance 39, so that the tar is restrained from flowing out toward a gas nozzle 8. Since the filter 35 is composed of porous material so as to increase its cross-sectional area and provided with the clearance 39 on the upper part, the filter 35 is hard to clog even partly.
