IPC: G01D7/00
Filed: 1985-06-17
Abstract: PURPOSE:To improve visibility by arranging many segment electrodes for bar display in one row along a display scale and successively impressing voltage to these segment electrodes. CONSTITUTION:A liquid crystal driving circuit 23 successively impresses the voltage between the segment electrodes 20... on the side where the speed scale is small and a common electrode 21 by the calculation signal from a microcomputer 24 when the traveling speed of a motor bicycle increases. Then the bar display of the black ground corresponding to the shape of the electrodes 20... is made on the display plane of the white background. If the speed increases from the order of 10km/h to the order of 20km/h, the bar display is made by the segment electrode 20' but overall length is longer than the electrodes 20... which already marks the bar display on the electrode 20' and in addition an extension part 26 extending on the upper side of the electrodes 20... is provided and therefore the bar display on the display plane spreads to the part displaying the order of 10km/h. Therefore the display area of the bar sharply increases at every increase of the vehicle speed by 10km/h, by which the bar display is stressed.

Filed: 1977-11-02
Abstract: PURPOSE:To enable temperature to be optically detected by constituting a temperature sensing head with a capsule whose inside wall is coated with a reversible thermocolor paint and using this and optical fibers. CONSTITUTION:A temperature sensing head 1 is constituted by making the bottom plate 13 of a capsule 11 having vent holes 12 with a good heat conductor anc coating a reversible thermo-color paint 14 on the inside wall thereof. Two optical fibers 2, 3 with their ends being opposed to the reversible thermo-color paint 14 are mounted to the temperature sensing head 1 and the other ends of the optical fibers 2, 3 are optically coupled with a light emitting diode 4 and a photo diode 5 respectively. The light of the light emitting diode 4 is sent into the capsule 11 and the reflected light from the reversible thermo-color paint 14 is detected with the photo diode 5. When the temperature sensing head 1 is contacted to the position to be measured, the thermo-color paint 14 discolors owing to temperature change, hence the detection outputs of the photo diode 5 changes and therefore temperature measurement is made possible from this.

Abstract: PURPOSE:To improve the extent of guiding accuracy in a working hand by rephotographing a visual field of a camera means in changing a sense of setting value in this outer end direction in the case where the end of a specific color range comes into contact with the outer end of a camera field, and re-extracting a geometric feature point on the basis of this image information. CONSTITUTION:Whether the end of a specific color range comes into contact with the outer end of a camera field of a camera means S1 or not is discriminated by a discriminating means 103. Next, when the end of the specific color range comes into contact with the outer end of the camera field as a result of discrimination of this means 103, a sense of sight of the camera means S1 is changed in the outer end direction of the camera field where the specific range is contacted. In this changed state, rephotographing takes place, and on the basis of this rephotographed image information, a geometric feature point is re-extracted by an extracting means 101, whereby false detection of position information on a working handle or a working object is prevented from occurring. In consequence, the extent of guiding accuracy in this working hand is improvable.

Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of improving startability. SOLUTION: An engine 1 is provided with four cylinders #1 to #4. An intake port 9 communicated with each combustion chamber 7 is arranged on a cylinder head 4, and an injector 17 for supplying fuel is arranged in the vicinity of the intake port 9 per cylinder. In an electronic control device (ECU) 51, in the case where a cranking continuous time is a predetermined time or more, it is judged that the engine 1 is not started regardless that cranking is carried out for a comparatively long period, and scavenging, namely, reduction of a fuel injection rate is carried out in only the cylinders #1 and #2. In the case where the necessity for scavenging is judged, the degrees of the demand for scavenging are different from each other by various conditions.  When the degree of the demand for scavenging is large, combustion is carried out in the cylinders #1 and #2 in which the injection rate is reduced. When the degree of the demand for scavenging is small, combustion is carried out in the cylinders #3 and #4 in which the injection rate is not reduced.
