Abstract: PURPOSE: To stop a correction of the fuel controller from a cooling water temperature at the time of failure, with the failure of water temperature sensor discovered, by making a comparison between a detected output of the engine temperature other than the water temperature sensor and an output of the water temperature sensor.  
     CONSTITUTION: In a case when the output of a water temperature sensor 7 shows a state of low temperature despite that the output of a sensor 8, for directly or indirectly detecting a temperature of the engine, such as, for instance, a temperature of catalyzer, exhaust gas or lubricating oil, etc., other than the engine cooling water temperature sensor 7, shows a state of high temperature of the engine, the output signal through comparators 10, 20 operates an AND circuit 12. A switching signal S 2  actuates a switching circuit 13 to switch the contact from A to B. To the contact B, for instance, is being applied an output voltage V 0  of the normal water temperature sensor 7 at a cooling water temperature of 80°C, therefore, the constant voltage V 0 , corresponding to the normal output, is applied to an arithmetic unit 1, thus a fuel control function can be prevented from being lowered after a completion of warm-up operation of the engine.

Filed: 1995-03-31
Abstract: PURPOSE: To facilitate the checking of a difference in an image between both eyes. CONSTITUTION: Optical system data 4 are divided into an optical system data 4a of the right eye and an optical system data 4b of the left eye. The optical system data 4a of the right eye and the optical system data 4b of the left eye are those when the same light source screen is viewed. PSF computing means 5 and 6 determine PSFs 7 and 8 separately based on the optical system data 4a and 4b. Retinal image computing means 2 and 3 perform a convolution integration of an image data 1 set as target based on the PSFs 7 and 8 to generate a right eye retinal image data 9 and a left eye retinal image data 10. A display control means 11 displays right and left retinal image data 9 and 10 on a display screen of a display device 12 so that right and left images are shown side by side within the screen in an easily comparable fashion.  Thus, a difference between images projection on the right and left retinas can be judged objectively by comparing the size, the blurring condition or the way of distortion between the right and left retinal images shown.
