Title: Method for deciding position of mobile station in wireless communication system
Inventor: PAUL MANSAN YAN
IPC: G01S13/74
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To provide the method and device to decide the position of a mobile station. SOLUTION: A mobile station 10 receives (through a synchronization channel) a transmission time stamp from a base station and sends a reception time stamp to the base station accordingly (through a pseudo spurious echo carrier deviated from a data carrier). The base station uses the time stamps to calculate a 1st range. Other 2nd and 3rd base stations execute the similar operation to above to calculate 2nd and 3rd ranges. The base station calculates a position vector and an azimuth by using the ranges and calculates the longitude and the latitude of the mobile station 10. The mobile station 10 uses a silent echo generating circuit for the transmission reception of the time stamps above.

Title: Radio communication system
Inventor: TOKUNAGA MITSUYOSHI
IPC: H04B7/26
Filed: 1992-01-14
Abstract: PURPOSE:To provided the radio communication system in which the transmission frequency of each base station is kept the same easily and inexpensively. CONSTITUTION:An amplifier 162 of an adjustment section 16 amplifies a carrier sent from an adjacent base station and outputs the amplified carrier to a mixer 163. The amplifier 161 amplifies the carrier of its own station outputted from a transmission section 15 and outputs the amplified carrier to the mixer 163. The mixer 163 mixes both the carriers and outputs the mixed carrier via an amplifier 164 to a frequency discriminator 165, in which the frequency is discriminated. A discriminator 165 applies frequency discrimination to a difference signal between the frequencies of both the carriers and an A/D converter 166 digitizes the result and it is outputted to a subtractor 154 of a transmission section 15. The subtractor 154 calculates the same frequency as the frequency of the transmission carrier of the adjacent base station based on the difference signal and the current oscillated frequency of the oscillator 151 and sets the result to a frequency setting section 153. Thus, the oscillated frequency of the oscillator 151 is coincident with the frequency of the transmission carrier of the, adjacent base station.

Title: System for transmitting radio packet
Inventor: SHIMIZU TOSHIMITSU
IPC: H04L12/28
Filed: 1989-01-13
Abstract: PURPOSE:To improve the transmission efficiency data by making the retransmission of a block from a system-side minimum and to reduce the over again transmission efficiency of data by adding an unreceivable packet number in a block reception failure number. CONSTITUTION:When a terminal (a) has normally received an m-th block, it transmits a block signal (block ACK) to a system and receives an (m+1)-th block from the system-side. When a first packet cannot normally be received, the terminal (a) transmits a block reception defective signal (block NAK), and adds the unreceivable packet number (i) into the signal. When the system-side receives the content that an i-th packet in the block NAK signal cannot be received, it retransmits only the i-th packet D(i) of the (m+1)-th block to the terminal (a). When the system-side receives the block reception normal signal from the terminal (a), the transmission of the (m+1)-th block terminates. Thus, the transmission efficiency of data is improved by setting the retransmission of the system-side as the minimum, and the over again transmission efficiency of data can be reduced.

Title: Optical fiber coupler and its production
Inventor: HANABUSA HIROAKI
IPC: G02B6/28
Filed: 1988-01-14
Abstract: PURPOSE:To obtain a 3dB branch optical fiber coupler which has the lower dependency of a branching ratio on wavelength and has a good yield at the time of production by providing fusion-stretched parts at >=2 points to said coupler and giving a difference larger than the coherent length of signal light between the lengths of the two optical fibers between the respective fusion- stretched parts. CONSTITUTION:The fusion-stretched parts are provided in series at >=2 points and the difference larger than the coherent length of the signal light is given between the lengths of the two optical fibers 1 between the respective fusion- stretched parts. Since the phases of the light signals are unified in the case of using a semiconductor laser, an interference arises but the problem can be solved by giving the difference larger than the coherent length of the signal light to the lengths of the two optical fibers between the fusion-stretched parts. The 3dB branching characteristics of the small dependency on the wavelength and good yield at the time of production are thereby obtd.

Title: Demodulation circuit
Inventor: OMORI HIDEKI
IPC: H03M5/04
Filed: 1985-01-16
Abstract: PURPOSE:To decrease the data error rate by outputting two kinds of signals, an output signal of a detection circuit and a DC voltage proportional to a frequency so as to collate the truth of the output signals. CONSTITUTION:A modulated signal received is amplified by a high frequency amplifier circuit 1 and mixed with an output signal of a local oscillation circuit 2 by a frequency mixing circuit 3. The mixed signal is demodulated by a detection circuit 4 and a DC voltage of two levels corresponding to ''1'' or ''0'' is outputted from the 1st output terminal 6. Further, an AC signal superimposed on the DC voltage is converted into a DC voltage proportional to the frequency by a frequencty-voltage converting circuit 5 and outputted from the 2nd output terminal 7. The data error rate is reduced even when a signal having a small difference between two corresponding frequencies of ''1'', ''0'' of a modulated wave or a signal superimposed with noise whose boundary is unclear is inputted by comparing and collating the signals outputted from the 1st and 2nd output terminals.

Title: Frequency adjustment method for strip line filter
Inventor: ITO KENJI
IPC: H01P1/205
Filed: 1990-01-12
Abstract: PURPOSE:To facilitate the adjustment of the frequency response characteristic of a filter by adjusting the frequency response characteristic of a resonance line with no thin strip short-circuit line formed in advance therein, and adjusting the frequency response characteristic while recovering the function of each resonance line whose fine strip short-circuit line is interrupted sequentially. CONSTITUTION:A reflection characteristic signal waveform s11 is measured for a resonance line 2a by utilizing an external connection terminal 4a. When the characteristic differs from a required value, the frequency adjustment is implemented. Then the reflection characteristic signal waveform S22 of other resonance line 2a is measured by utilizing an external connection terminal 4b and the frequency adjustment is implemented similarly. Then a thin strip short-circuit 5 is interrupted by making a hole 8 externally to obtain the state shown in Figure C. Then the reflection characteristic signal waveform S11 or S12 is measured again and the resonance frequency response characteristic of a resonance line 2c in the middle is adjusted by the similar means to above. Thus, even when the number of resonance lines is increased, the frequency response adjustment of the filter is easily and properly implemented.
