IPC: H01S3/104
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a laser by detecting the opened/closed state of a shutter by means of a reflection mirror and a photodetector which receives laser light reflected by the reflection mirror. SOLUTION: When laser light is needed, a detection shutter 21 is opened manually, and the laser light is extracted through a shutter window 20. The extracted laser light is split by means of a beam splatter 16, and one part of it is made incident to a photodetector 18. The photodetector 18 converts the received part into a laser light control signal and feeds back the signal to a laser light output control circuit 19. The circuit 19 controls the outputted laser light so that the fed-back signal becomes constant. When laser light is not needed, the shutter 21 is closed. When the shutter 21 is closed, the laser light is made incident to a second photodetector 24 through a reflecting mirror 23.  The photodetector 24 converts the received laser light into a signal for detecting the opening/closing of the shutter 21 and feeds back the signal to the control circuit 19, and the circuit 19 recognizes that the shutter window 20 is in a closed state and switches the mode to a standby mode.

IPC: G01B11/30
Filed: 1985-08-09
Abstract: PURPOSE:To make it possible to ensure the detection of unevenness of a road surface even when there is a change in color thereon, by determining the presence or absence of the unevenness of the road surface based on the ratio in intensity between reflected lights from first and second visual fields which are different in an area from each other.

Therefore the light- receiving element 6 receives naturally a reflected light from a first visual field, and the light-receiving element 7 receives naturally a reflected light from a second visual field. The ratio between signals having levels corresponding to the intensities of the reflected lights from the first and second visual fields which are outputted from said light-receiving elements 6 and 7 respectively is determined by a microprocessor 12, and based on the result of an operation, is determined whether there is unevenness on a road surface. According to this constitution, the unevenness of the road surface can be detected surely even when there is nonuniformity in color on the road surface.

Filed: 1983-09-24
Abstract: PURPOSE:To prevent the engine-stop by supplying fuel in advance when a clutch is placed in OFF-position in an intermediate running range between a specified restored number of revolution being a standard when the fuel cut is released and a limit number of revolution for avoiding the engine stop. CONSTITUTION:When a car is decelerated, a fuel cut signal (b) is given from the fuel cut control unit 11 of a fuel cut mechanism 4 and a fuel cut valve 6 is fully closed. In this state, when the engine speed detected by an engine speed sensor 12 exists in an intermediate range between a restored number of revolution (for example 900rpm) and a little higher limit number of revolution (for example 1,200rpm) for avoiding the engine stop, and then a clutch switch 14 or a neutral switch 13 is changed from OFF- to ON-position, the fuel cut is released. Thus, an electromagnetic pump 25 is driven only for a fixed time so as to supply a specific quantity of fuel to a carbureter 2, while the throttle valve 2 may be rapidly opened only by a specific angle.
