    摘要： An object of the present invention is to prevent a device portion from being electrostatically charged with the use of the high resistivity film, and at the same time prevent a leak current passing the device portion due to an existing high resistivity film, in an electron source with the use of a surface-conduction electron-emitting device. This process for manufacturing the electron-emitting device comprises the steps of: forming an electroconductive thin film 4 astride device electrodes; forming the high resistivity film 7 in a region except the electroconductive thin film 4 and a perimeter thereof; subjecting the electroconductive thin film 4 to forming processing, to form a fissure 5 therein; and depositing a carbon film 6 inside the fissure 5 and in a region reaching the high resistivity film 7 from the edge of the fissure 5, by applying voltage between device electrodes 2 and 3 under an atmosphere containing a carbon compound.

    摘要： An underground water channel is provided in an underground of a large depth, and rain water and the like flow into this underground channel from flood control channels, conduits and rivers through vertical shafts. A pump well of a pump station is connected to a downstream end of the underground channel, and water flowing into the pump well is discharged by a pump to a discharge tank. The pump is disposed generally at a medium water level of the underground channel, and a lowest water level L.W.L enabling draining is the medium water level of the underground channel. In an open channel flow operation of an open channel-closed channel mixed flow operation, water level of the underground channel is maintained at the lowest water level L.W.L, so that the underground channel is in an open channel condition. In the closed channel flow operation, the underground channel is fully filled with water, and further water level rises into the vertical shafts, so that the underground channel is in a closed channel condition. By changing an outflow factor in accordance with rainfall patterns, the rate of flow into the vertical shafts can be accurately estimated, so that the large-depth underground drainage facility can be run in a stable manner.

    摘要翻译： 深水地下设有地下水道，雨水等通过垂直井从防洪通道，管道和河流流入该地下通道。 泵站的泵井连接到地下通道的下游端，流入泵井的水通过泵排出到排放罐。 泵通常设置在地下通道的中等水位，并且能够排水的最低水位L.W.L是地下通道的中等水位。 在开放通道封闭通道混合流动操作的开放通道流动操作中，地下通道的水位保持在最低水位L.W.L，使得地下通道处于开放通道状态。 在封闭通道流动操作中，地下通道充满水，水位进一步升高至竖井内，使地下通道处于封闭通道状态。 通过根据降雨模式改变流出因子，可以准确估计垂直井的流量，从而可以稳定运行大型地下排水设施。

    摘要： A vertical shaft type pump including a bearing device in which water in the pump is utilized as lubricating water without supplying water to the bearing from the outside of the pump, thereby repeatedly conducting no-load operation in the air (in such a state that water is not pumped) stably for a long period of time. In the pump, a water storage tank upwardly opened is fixed to a rotary shaft, and the lubricating water (the water in the pump) is retained within the water storage tank so that the bearing is operated while being always soaked in the lubricating water. Also, foreign substances in the water storage tank are mixed with the water without deposition, and the water containing the foreign substances is replaced by the newly pumped water.
