Title: Diaphragm controlling system for television camera of automatic plate-number reading equipment
Inventor: KATO KENJI
IPC: H04N5/238
Filed: 1985-12-06
Abstract: PURPOSE:To stably read the plate-number of a vehicle regardless of the day, night, follow-light or counter-light by inputting illumination information from an illumination detector to the control circuit of a motor to control the diaphragm of a television camera, by totaling the said information with date information and information inputted from a vehicle detector to control the said diaphragm. CONSTITUTION:A lens 2.9 is directed to the road. A photoelectric conversion element 2.10 is positioned on the image-forming plane of the lens 2.9 corresponding to the scope of a camera 2.8. And the output from the element 2.9 is inputted to a signal processor 2.11. The processor 2.11 obtains the illuminance L within the scope from the output of the element 2.10. The processor 2.11 compares the illuminance L with L1 (a constant), and if judges that illumination is necessary for the image-picking-up in case, for instance, it is night, instructs an image-pick-up controlling circuit 3.4 of the need for illumination. If the weather is judged to be clear, the position of the sun is calculated from the date and the time is obtained from a clock 23, and the result is compared with the setting-condition of the television camera 3.2 to determine the degree of opening of the diaphragm from the representative value E of the brightness of a video.

Title: Truck for caisson
Inventor: KIZARA YUKIO
IPC: B61D47/00
Filed: 1994-11-10
Abstract: PURPOSE: To make it compact in size and lighter in weight as well as to simplify its structure by installating an oil tank supporting a jack cylinder by means of hydraulic pressure and an accumulator controlling the hydraulic pressure in the oil tank in response to load to be imposed on the jack cylinder, respectively. CONSTITUTION: While a caisson is moved by a truck, if there is wave motion in a rail, excessive load is imposed on each of jack cylinders 33a and 33b. In this case, a cylinder rod will not go down unless it is connected to a pipe 95. Since these jack cylinders 33a and 33b on the whole are pushed downward by their own weight, however, oil in two oil tanks 77a and 775 floating these cylinders 33a and 33b is pressurized, and this pressure is imposed on an accumulator 37 via a pipe 101. This accumulator 37 compresses the extent of nitrogen gas filled up in response to hydraulic pressure, and the whole of these jack cylinders 33a and 33b, on which undue load is imposed in response to the portion, is lowered in the oil tanks 77a and 77b, and thus an interval between both the jack cylinders 33a and 33b is equilibrated.

A change in color after photographing under a fluorescent lamp is reduced by the combination of the dyes and the lowering of the sensitivity of the green-sensitive layers due to the dyes is compensated by the cyan coupler without lowering saturation. A silver halide color photographic sensitive material ensuring high saturation and hardly causing a change in color after photographing both under daylight and under a fluorescent lamp is obtd.
