Title: Apparatus for recognizing position of vehicle
Inventor: SUNAGA YUICHIRO
IPC: G08G1/16
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To improve measurement accuracy for a distance between vehicles by arranging three or more identification means at a rear face of a vehicle body of a preceding vehicle and measuring a relative position to the preceding vehicle on the basis of a binary image. SOLUTION: Three IR(infrared ray)-LEDs 2 are arranged at position of angles of an isosceles triangle at a rear face 1a of a body of a preceding vehicle 1. An IR-camera 4 for photographing the rear face of the body of the preceding vehicle 1 and an image-processing device are set at a following vehicle 3. The image-processing device converts an input image from the IR-camera 4 to a binary image of a brightness level. The IR-LEDs 2 are divided with the rear face 1a of the preceding vehicle 1 at the background, so that three bright pints A1 -A3 are given to the binary image. In order to obtain a coordinate position of each bright point A1 -A3 , a histogram in an (x) direction and a (y) direction is formed from the binary image. The coordinate position of each bright point A1 -A3 is determined from the histogram.  A distance between bright points is calculated from the coordinate positions, and a distance between the vehicles is obtained from the calculated values, a focal length of a camera lens and an actual distance between bright points.

Title: Small water boiler
Inventor: KATSUHARA HIROTOSHI
IPC: F23N1/00
Filed: 1986-11-13
Abstract: PURPOSE:To simplify constitution and to enable control of slow ignition, by a method wherein, in a smaller water boiler for a kitchen, a capacity switching valve for switching the thermal power of a burner is located in the combustion flow passage of the burner, and ignition motion of the burner causes closing of the capacity switching valve. CONSTITUTION:The fuel flow passage of a gas burner 16 is branched into first and second flow passages 22 and 23, and a capacity switching valve 24 is situated in the second flow passage 23. With a control panel 4 switched ON, the capacity switching valve 24 is controlled through a control circuit 35 by the working of a self-holding type solenoid 25''. Namely, when a start and stop switch 6 is turned ON in a state that a capacity change-over switch 8 is set to high combustion position, the self-holding type solenoid 25'' is energized to close the capacity switching valve 24. Thus, for a fuel passage, only the first flow passage 22 is rendered effective to switch for slow ignition. This constitution simplifies constitution and enables direct ignition of even a small water boiler.

Filed: 1994-11-04
Abstract: PURPOSE: To prevent unnecessary clock switching operations when a clock signal switch control package is inserted by producing a clock switch signal based on the selection signal of each clock supplied package in the insertion mode of the clock signal switch control package. CONSTITUTION: A discontinuity detection means 13 inputs the clock signals C01 and C02 of two systems, and the discontinuity detection circuits 131 and 132 detect the discontinuity of wires and output the wire discontinuity detection signals S05 and S06 respectively. When a clock signal switch control package 2 is inserted, a signal R is transmitted from a power-on reset circuit 21 and at the same time a mounting signal S02 is also transmitted. Under such conditions, a clock switch signal S04 is equal to a selection signal S03 and a selection circuit 11 is not switched. When the package 2 is pulled out, a clock switch signal is produced based on the selection of a clock supplied package 1 and the circuit 11 is not switched. Thus the unnecessary clock switching operations can be prevented when the package 2 is inserted and pulled out.

Abstract: PURPOSE:To detect a moving target alone such as airplane accurately, by employing only one FIR filter using a selected filter coefficient to remove a clutter having a Doppler speed such as rain clutter efficiently. CONSTITUTION:A pulse pair type circuit which comprises a sweep memory 2, a complex type multiplier 3, a bearing average circuit 4 and a tan<-1> table 5 determine a Doppler velocity of rain clutters.
