Title: Stereoscopic image device
Inventor: NISHIKAWA KOHEI
IPC: G01B11/245
Filed: 1989-04-07
Abstract: PURPOSE:To easily and accurately measure the spatial position of a body in a stereoscopic image by calculating the spatial position by retrieving a correspondence area centering the position of a cursor. CONSTITUTION:A three-dimensional graphic control circuit 13 outputs the three- dimensional position of the cursor K to a focus control circuit 14, and the focus control circuit 14 controls two video cameras 2 and 3 so as to obtain the focusing of the cameras 2 and 3 on a supplied three-dimensional position. Furthermore, an instruction to calculate the spatial position is issued to an image processing processor 15 via an instruction means such as a keyboard, etc. The image processing processor 15 stores the photographing images of the video cameras 2 and 3 in image memories 16 and 17, respectively, and sets a reference window W0 in the periphery of the cursor Kf at a left image 2a, and the correspondence area (e) centering the position of the cursor Kr at a right image 3a. In such a way, since the desired part of a targeted body exists in the correspondence area (e), it is enough to retrieve only the correspondence area, and the measurement of the position of the body easily and accurately is performed by using the stereoscopic image.

Title: Control system of ignition of engine
Inventor: FUJII MASAHIKO
IPC: F02P5/15
Filed: 1982-05-28
Abstract: PURPOSE:To enable ignition positively even on sudden acceleration by deciding the security of a feed time to an ignition coil just before reference positional pulses are generated and forcedly starting feed when the feed time is insufficient. CONSTITUTION:The feed time and a1 are compared at a step 13. The feed time represents a conduction time to the ignition coil and a1 time up to an ignition timing where a generating time of a count start signal F is used as a base point. When the feed time is shorter than the time a1 on sudden acceleration, the step advances to a step 15, and feed is started. Accordingly, positive ignition is enabled even on sudden acceleration because conduction can be started forcedly when the feed time is insufficient.

Abstract: PURPOSE:To dispense with the concept of a measuring range, to eliminate a span drift and to enable stable measurement of the concentration of gas by regulating the concentration of a reference gas by a reference gas regulating means so that a detection value from a gas analyzer maybe zero. CONSTITUTION:When a signal from a detector 16 is inputted to a reference gas regulating means 5, the regulating means 5 regulates flow rates of a zero gas (e.g. N2 gas) refined by a zero gas refining unit 3 and a standard gas (e.g. CO2 gas of prescribed high concentration) from a standard gas cylinder 4, in a feedback manner, so that the detection signal be zero, and makes an indicator 21 indicate the concentration of a reference gas thus regulated, as the concentration of CO2 in a sample gas at that time point. According to this constitution, a measuring range is determined by the capacity of the regulating means 5 irrespective of a measurable range of a gas analyzer 20 and the concentration of CO2 having a large fluctuation width can be measured. Besides, a span drift of the analyzer 20, itself, vanishes, the effect on a measured value is eliminated and specification stability is improved.
