Title: Automobile navigator
Inventor: SAKASHITA NAOHIRO
IPC: G10L15/00
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To know a current traveling site even during driving an automobile. SOLUTION: A controller 6 obtains a current site with signals from a GPS receiver 1, a gyro 2 and a wheel speed sensor 3 and displays the current site and a road map on a display 7 with map data from a map data storage 4. When a voice recognizer recognizes a driver's voice meaning the current site, information on the current site is generated as voice from a voice generator 9. Further when the voice recognizer 8 recognizes a voice meaning a specific site such as a place name or a facility name, it calculates a positional relation between the specific site and the current site for generating the positional relation as voice from the voice generator 9. For example a voice such as 'go ahead ΔΔkm more to south west' is generated.  Such voice generation allows the driver to know the current site easily from a relation with the specific site known to the driver even while driving an automobile.

Title: Unload valve
Inventor: OOKI HIROSHI
IPC: G05D7/01
Filed: 1981-07-29
Abstract: PURPOSE:To furnish an unload valve which maintain a constant descending speed of a table gate and the like of a car with an additional function of a flow rate regulator valve, by providing said valve with a backpressure chamber which contributes to actuates a backpressure to close a return passage of oil pressure. CONSTITUTION:A backpressure chamber 32 communicating with a return passage 8 is made in a valve main body 2. When descending speed of a piston of a cylinder 28, that is, speed of returning flow of pressure oil is increasing due to a big force 30 working on a table gate, the pressure in the backpressure chamber 32 grows high and pushes up a valve spool 10 against tension of a spring 20, working so as to close the return passage 8 by means of an extended head 12. When the return passage 8 is closed, the pressure in the backpressure chamber 32 is lowered and the valve spool is again pushed down by the returning pressure oil to open the return passage 8. Thus, quantity of flow through the return passage 8 is always maintained constant regardless of the magnitude of external load 30.

Title: System of measuring dispersion characteristic of optical fiber
Inventor: RYU SHIRO
IPC: G01M11/02
Filed: 1988-05-18
Abstract: PURPOSE:To measure dispersion characteristics with high resolving power and high accuracy by using a distributed feedback semiconductor laser having excellent single vertical mode oscillation characteristics as a light source. CONSTITUTION:The wavelength of a measuring light signal L1 emitted from a laser 2' for measurement which is the distributed feedback semiconductor laser is measured 12. The difference of the oscillation wavelength of a laser 10 for monitor from the measured 12 wavelength of the laser 2' is sufficiently lessened by adjusting driving current or temp. The measuring light signal L2 subjected to branching 9 and the monitor light signal L0 are synthesized 13 to form a beat signal L component of both the waves. This component is photoelectrically converted to an intermediate frequency electric signal Sc by an optical receiver 5c and is observed on a spectrum analyzer 11. The change in the wavelength from the initial oscillation wavelength is thereafter observed on the analyzer 11 and the output signal S is simultaneously measured, by which the dispersion characteristics are measured with the high resolving power and high accuracy.
