Title: Detection of position of self-propelled vehicle
Inventor: MAEDA AKIO
IPC: G01C15/00
Filed: 1987-03-30
Abstract: PURPOSE:To enable the accurate position of a self-propelled vehicle to be measured by detecting at least two light sources arranged in a building by detecting means aboard the vehicle and measuring angles theta formed by the vehicle and the two light sources or inclinations phi with respect to the light sources. CONSTITUTION:A television camera 2 is rotated so that a light source A is positioned in the center of the screen of the camera 2 by driving servo motors 7 and 12 in directions theta and phi, respectively, by the output signals from a CPU 3. The values of counters 9 and 14 at this time are sampled in the CPU 3. In the same manner as above, for light sources B and C, the values of the counters 9 and 14 are sampled in the CPU 3 when the light sources B and C are positioned in the center of the screen. Thus, the CPU 3 measures theta1 and theta2 on the basis of the sampled counter values and conducts a calculation by the accompanying expressions I to detect the position P of a self-propelled vehicle. In the expressions I, A-C designate the light sources and theta1 and theta2 designate angles formed by the light sources and the position P(x, y) of the self-propelled vehicle.

Abstract: PURPOSE:To remove phosphorus in waste water stably and efficiently, by passing waste water through a reaction tank in an anaerobic state then through a reaction tank in an aerobic state in accordance with >=3 units of reaction tanks which repeat the anaerobic state and the aerobic state alternately at every prescribed time. CONSTITUTION:When valves 16C, 20B, 30 are opened and the other valves are closed, the waste water from a pipeline 14 for introduction of waste water is first introduced into a reaction tank 10C, then the water flows in order of reaction tanks 10D, 10E, a communicating pipeline 28, and reaction tanks 10A, 10B, until the water arrives at a settling tank 22 through an outflow pipeline 18. The weir plate of a partition plate 12B in this state dams up the reaction tanks on both sides and the other partition walls communicate the reaction tanks on both sides with each other. The tanks 10C, 10D, 10E in this state are maintained anaerobically and the tanks 10A, 10B aerobically, and the phosphorus in the waste water is removed. The shifting to the next stage is accomplished by opening and closing the valve, opening and closing the weir plates of the partition walls and changing over the anaerobic and aerobic means of the respective reaction tanks.

Filed: 1984-04-23
Abstract: PURPOSE:To obtain a speaker unit capable of reducing the interference of sounds by disposing acoustic resistance paltes having plural holes on a front surface, rear surface or both surfaces of a diaphragm. CONSTITUTION:A front surface acoustic resistance plate 10 is fitted on a diaphragm 4 through a gasket 8. Plural small holes 20 and 21 are drilled on the resistance plate 10, and the diameter of the hole 20 at the center is larger than that of the hole 21. The total area of these holes is decided to be 20-30%. Plural holes 30 are drilled on a frame 5, and formed in a slender shape at same intervals along a periphery of a coil 2, thereby functioning as a rear surface acoustic resistance plate. By providing acoustic resistance plates before and after the diaphragm 4 in such a way, sounds in a low frequency can be escaped through holes formed around resistance plates 5 and 10, which is effective in canceling out of low frequency parts and makes turning-around smaller.

IPC: B21B45/02
Filed: 1987-04-01
Abstract: PURPOSE:To prevent generation of shape defects of a product by cooling to eliminate a temp. difference between upper and lower parts of a flange and hot straightening cambers caused by the cooling. CONSTITUTION:A cooler 3 and a straightener 4 are sequentially installed along the pass line of a finishing rolling mill 2 for an H-shape steel 1. The inside of the cooler 3 is provided with water cooling nozzles 3a, 3b which respectively cool an upper part 11 and a lower part 12 of a flange 10 and a controller 6 is also installed in the inside. The H-shape steel 1 delivered from the mill 2 enters the cooler 3 and is subjected to a cooling treatment eliminating a nearly total amount of a temp. difference between the upper part 11 and lower part 12 of the flange 10. Then, the straightener 4 hot straightens cambers on the H-shape steel caused by the cooling treatment. Generation of shape defects of a product after cooling is prevented because straightening is performed by giving the steel 1 a bending amount proportional to a deformation caused by cooling.
