Title: Vehicle discriminating method
Inventor: FUKAGAWA HARUMI
IPC: G01M17/007
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to discriminate the kinds of many vehicles without changing the vehicle-kind discriminating CPU and the like by comparing the device code provided in the electronic device of the object vehicle and the device code that is set in correspondence with it when the vehicle-kind data of the object vehicle and the preset vehicle-kind data agree with each other. SOLUTION: A vehicle-kind judging means 7 of a discrimination control means (CPU) 6 inputs the vehicle-kind data WD inputted from a vehicle-kind discriminating tester 1 as the vehicle-kind data DS, compares the data with the preset vehicle-kind data DV of a data memory means 5 and discriminates the vehicle as the 'default vehicle kind' when the data do not agree. When the data mutually agree, the device code DC provided in the electronic control device is outputted. An input-device-code judging means 8 compares the code with the device code NA of the unit A of an electronic control unit 3. When the codes agree, 'vehicle-kind settlement' is discriminated. Thus, the discrimination of the many vehicle kinds can be performed without changing the CPU and software for the vehicle-kind discrimination only by preparing the data table of the device codes in correspondence with the vehicle-kind data of the number of the object vehicle kind for the discrimination.

Title: Variable wavelength laser equipment
Inventor: SUZUKI TAKASHI
IPC: H01S3/16
Filed: 1993-07-27
Abstract: PURPOSE:To provide a variable wavelength laser capable of varying wavelength at high speed with little noise. CONSTITUTION:As a laser medium 300 is irradiated with excitation light emitted from an excitation light source 100, fluorescence occurs over a wide range of wavelengths. Part of this fluorescence is inputted via an aperture 410 to an electro-optical crystal 5 in which a refractive index distribution is generated by voltage impression. Rays of light in the electro-optical crystal 500 have a different deflection for each wavelength and are outputted to reach a reflector 220. Of the rays of light entering the reflector 220, only those rays of wavelengths deflected to a specific direction are reflected to the resonance optical path direction to meet the resonance requirement. Because only those rays of light having wavelengths meeting this resonance condition re-enter the laser medium and induce an emission, the wavelength of outputted light is selected by controlling a voltage impressed on the electro-optical crystal 500 through operation of a voltage controller 620.

Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To provide an excellent expanded image hardly presenting a blurred image by detecting luminance of a monitored image and narrowing a diaphragm in a diaphragm part more as the luminance is higher. SOLUTION: By means of a luminance detection circuit 20, luminance of a monitored image is detected, and in compliance with the luminance, a diaphragm in a diaphragm part 18 is narrowed more by means of an actuator 19 as the luminance is higher. As a result, the luminance is secured to the extent to which difficulty in visibility for the image is not raised, and a blur of the image can be reduced effectively. Consequently, diaphragm adjustment can be carried out while taking both of an image blur and image brightness into consideration, and a monitored image with excellent visibility can be displayed on a monitor 12.  As a monitor area expansion member 2, an optical member, which is arranged between an image pickup means and an object and can expand an image pickup area provided by the image pickup means by letting object light of a wide angle be incident on the image pickup means, may be usable.

Title: Phase detection circuit
Inventor: OKADA YUKIHIRO
IPC: H04L27/22
Filed: 1985-08-23
Abstract: PURPOSE:To prevent a malfunction by setting the offset voltage of a phase demodulation data with an external power voltage and adding it to one phase detection output terminal of a double balanced mixer so as to compensate the fluctuation of the power voltage. CONSTITUTION:A power supply 8 is to supply an operating voltage for differential amplifiers 5, 9, 9 and the offset voltage of a phase demodulation data is fed to the other input of the amplifier 5 from a power supply 8. Further, the offset voltage is subjected to noise cut through a filter 3 and fed to the IF2 terminal of a double balanced mixer DBM1. Thus, the offset voltage C of a position detection signal and the offset voltage D of a phase demodulation data signal are coincident more surely than setting the offset voltage fed to the IF2 terminal separately. Thus, the possibility of generation of an error signal based on the change in the amplifiers 5, 9, 9 due to power voltage fluctuation is precluded.
