Filed: 1993-11-02
Abstract: PURPOSE:To achieve use over wide wavelength range with a simple and inexpensive structure by serially connecting two optical couplers without any wavelength dependency of a specific branch ratio. CONSTITUTION:For example. two single modes 1313-1550WIC 21 and 22 are serially connected as an optical fiber coupler (WIC) with a branch ratio of 50%, without any wavelength dependency at a wavelength region of 1.3-1.55mum and then a light path difference DELTAL is created at a light side, where the light path length changes according to the physical quantity such as stress given to a sensor. Then. for example, the light path difference DELTAL is set to 1.38mm. light with a wavelength of 1.3-1.55mum is applied. and then output p1 and P2 applied from the WIC 21 and 22 are measured by light reception elements 17 and 18, thus measuring the physical quantity such as stress given to the sensor. As a result. the title interferometer operates as the interferometer in a wide range with a wavelength of 1.3-1.55mum and can be used as a light branching wave synthesizer with an extremely small wavelength difference of DELTAL.

Filed: 1988-11-25
Abstract: PURPOSE:To always read a bar code with high reliability by abutting a cam top with a holding case by pressing and separating a contactor from the bar code written surface of a medium at the initial position of a sensor driving body. CONSTITUTION:When a sensor driving body 10 is moved to its initial position after reading completes, a cam top 23 abuts with an abutting part 19e of a holding case 19, and accompanying this, a contactor 19d moves down in a separating direction from the rear face of a business card 30. Consequently, it becomes unnecessary to fear that the transfer of the business card 30 is obstructed by the contactor 19d, and it also becomes unnecessary to fear that the contactor 19d is caught in the business card 30 and broken by inserting and ejecting the business card 30 under a state in which the sensor driving body 10 stands by at its initial position. Thus, the bar code can be always read with high reliability.

Abstract: PURPOSE:To reduce the operating load of an operator by judging the stop instruction timing for reproduction of voices from the document input state or the internal processing state for KANA (Japanese syllabary)/KANJI (Chinese characters) conversion, etc. and stopping temporarily the reproducing action by the instruction signal. CONSTITUTION:A CPU 10 performs the overall control of a document processor as well as various types of document processing including the KANA/KANJI conversion. A voice reproducer 20 receives the reproduction start signal from the CPU 10 to carry out reproduction and interrupts the reproduction after receiving the reproduction stop signal. The reproduction stop signal is delivered when a reproduction stop mode set with combination of specific keys of an input part 11 is coincident with the 1st reproduction stop mode and when the KANA/KANJI reproduction is through with the character string stored in an input buffer 15. Then said reproduction stop signal is also delivered when a 'conversion' key is operated for indication of the KANA/KANJI conversion in the 2nd reproduction stop mode.

Abstract: PURPOSE: To enable a GPS navigation device to continuously output its present position with high accuracy regardless of the number of receivable GPS satellites by providing a measuring section, etc., which measures the changing rates of the pseudo ranges to the GPS satellites. CONSTITUTION: A switching section 10 sends the measured results of a pseudo range changing rate measuring section 8 to a first calculating section 12 which calculates the speed vector of moving bodies when a receiving state judgment section 6 judges that the number of receivable satellites is 3 or to a second calculating section 16 which calculates the speed vector of moving bodies when the judged number is less than 3. The section 12 calculates the speed vector of a moving body by using the present position information of the moving body measured by means of a GPS position measuring section 7 and the changing rates of the pseudo ranges to the satellites measured by the measuring section 8.  The section 16 calculates the speed vector of the moving body from the changing rates of pseudo ranges, pseudo ranges measured by a pseudo range measuring section 9, and the advancing bearing of the moving body calculated by a moving body advancing bearing calculating section 14. A moving body position estimating section 18 estimates the present position of the moving body by integrating the speed vectors.

Title: Optical pulse pattern generator
Inventor: ABE SHIGERU
IPC: H04B10/556
Filed: 1988-11-25
Abstract: PURPOSE:To stably obtain an optical pulse pattern in an ultrahigh frequency amounting to several tens of GHz by collecting optical short pulses from plural optical pulse generators into one output while deviating the phase. CONSTITUTION:Signals with deviated phases are outputted from plural synthesizer oscillators 2(1)-2(n) and optical short pulses are outputted from optical pulse generators 3(1)-3(n) based on the signal. Since the phases of the optical short pulses are deviated, an optical mixer 4 collects them into one output, then an optical pulse pattern in an ultrahigh frequency whose phase deviation corresponds to one period is generated repetitively. Thus, the optical pulse train in ultrahigh speed reaching the GHz - THz is stably generated.
