Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To obtain a judgment apparatus by which the state of the abnormality of a water level can be specified simply even when the abnormality of the water level is eliminated after the report of the abnormality of the water level by providing at least one out of a container which is arranged near the level of a water surface judge to be filled fully and a float which is fitted into a longer body suspended down to the height position of a water surface judged to be reduced. SOLUTION: When a manhole lid 3 is opened, water is filled into a container 6, and a float 7 is fitted into a longer body 5, then, a filled-water abnormality is judged. When water is not filled into the container 6, and the float 7 comes off from the longer body 5, then, a reduced-water abnormality is judged. That is to say, in the case of the filled-water abnormality, a water level becomes higher than the lower end of an electrode rod 20. Water is filled from the upper edge of the container 6, and the water is left inside the container 6 even when the water level is returned. The float 7 is moved only upward even when the water level is raised, and it is left so as to be fitted into the longer body 5. In the case of the reduced-water abnormality, the water level becomes lower than the lower end of an electrode rod 2B, and the float 7 comes off from the longer body 5. Even when the water level is returned, the float 7 is left so as to float on a water surface. The container 6 is kept empty.

Title: Recording method
Inventor: TAKANASHI RYOYU
IPC: G03G15/00
Filed: 1990-02-23
Abstract: PURPOSE:To perform high-sensitivity recording even when impressed voltage between 1st and 2nd electrodes is made low by making the photoconductive layer a charge injection type. CONSTITUTION:The electric resistance value of the photoconductive layer 14 is changed corresponding to the formed optical image of an object 19, and a DC power source Vb is connected between the transparent electrode 31 of the layer 14 and the electrode 15 of an optical modulation layer 11. Therefore, the intensity of the electric field on the boundary 21 between the layers 14 and 11 is changed according to the change pattern of the electric resistance value of the layer 14, and a charge image formed on the boundary 21 between the layers 14 and 11 becomes a charge image corresponding to the optical image of the object 19. Even when the layer 11 has low impedance, a charge supply quantity to the boundary 21 between the layers 14 and 11 is increased because the transparent electrode 31 is directly formed on the layer 14 to be charge injection type. Thus, the high-sensitivity recording is performed even when the impressed voltage between the 1st and the 2nd electrodes is made low.
