Title: Mobile communication terminal
Inventor: IWASAKI HIROTOSHI
IPC: G09B29/00
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To appropriately decide and delete a former file to be unnecessitated by newly acquiring a map data file. SOLUTION: A file (file B) matched with a portion excepting for a numeral part in the file name of a file (file A) newly acquired from an information distribution center is found out of an external memory (S140) and all the files in the area overlapped with the file B among the new files acquired later than the file B are extracted (S160). In the state of synthesizing the area of each of the extracted files and the area of the file A, it is discriminated whether that synthetic area includes all the area of the file B or not (S170). When the synthetic area includes all the area of the file B (S170: YES), the fact shows map data in the area covered by the file B are updated by the map data file acquired later than that file B so that the relevant file B is deleted from the external memory (S180).

Title: Luminance and chrominance signal separator circuit for television signal
Inventor: HIRANO YASUHIRO
IPC: H04N9/78
Filed: 1995-05-29
Abstract: PURPOSE: To conduct separation processing with less deterioration in image quality for television signals of both the NTSC system and the EDTV-II system by discriminating it to be the NTSC system when a signal of a specific scanning line of the television signal is a video signal and to be the EDTV-II system when the signal is an discrimination control signal. CONSTITUTION: A television signal VS at a base band is given to an A/D converter section 1, in which the signal is converted into a digital signal S1 at a sampling frequency being a multiple of four of a chrominance subcarrier, the signal S1 is fed to a memory section 2 and a system discrimination section 15. The system discrimination section 15 discriminates whether a signal of a specific scanning line is a video signal or an identification control signal. In the case of the video signal, the section 15 provides an output of a control signal MOD in the mode N representing the NTSC system and in the case of the identification control signal, the section 15 provides an output of the control signal MOD in the mode E representing the EDTV-II system.  Then the luminance signal and the chrominance carrier signal are separated with respect to the signal of the NTSC system and the luminance signal, the chrominance carrier signal and a horizontal resolution reinforcement signal are separated with respect to the signal of the EDTV-II system.

IPC: H01L29/73
Filed: 1989-05-24
Abstract: PURPOSE:To enable the running time of a minority carrier which is impregnated from an emitter to be reduced and improving operating speed by constituting a base in a specific double-layer structure and generating an incorporated electric field within the base.

Title: Dc power supply circuit
Inventor: SENBA KAZUHISA
IPC: H02M7/06
Filed: 1994-05-09
Abstract: PURPOSE:To raise load voltage immediately after turning on a power supply, that is, to enhance the root mean square value of a DC output voltage by connecting two capacitors between output terminals of a full-wave rectifying circuit for full-wave-rectifying an AC power supply and providing a specific capacitance ratio between these capacitors. CONSTITUTION:Individual capacitors C21, C22, C23,... have the same capacitance as that of the capacitor C1. The total capacitance C2 of the parallel capacitors C21, C22, C23,... is 2 to 3 times the capacitance of the capacitor C1. These but a capacitors can be replaced by a single capacitor having the equivalent capacitance. Therefore, the capacitance ratio between the capacitor C1 and C2 is more than 1:2, therefore, when a potential division ratio of capacitors to be charged in series during current closing changes and discharges in parallel, a capacitor voltage having a higher charging voltage with a lower capacitance becomes a load voltage. By doing this, a high power factor is obtained and the load voltage immediately after turning-on of the power supply can be raised.

Title: Estimation of component spectrum
Inventor: RICHIYAADO EFU REISHII
IPC: G01N30/86
Filed: 1988-05-27
Abstract: PURPOSE:To enable estimation of a component spectrum of a chromatogram with overlapped component peaks, by analyzing round peaks in a plane of a main factor. CONSTITUTION:A mixture of two component spectrums is on a linear segment determined by points indicating individual spectrum components in a main factor plane. When a linear segment is extrapolated indicating two binary mixtures having a common component, an intersection is obtained to indicate a spectrum of the common component. So, a distribution of all component spectrums in sections can be determined by employing the extrapolation. When more than two components appear, round peaks in the plane of the main factor are analyzed in a spectrum curve containing only three peaks, namely, a peak selected and peaks immediately before and after the peak, thereby enabling the estimation of a component spectrum of a chromatogram with overlapped component peaks.
