| 20110284752 | INSIDE-TUBE-WALL RADIOACTIVE CONTAMINATION MONITOR, AND MONITORING DEVICE AND METHOD USING THE SAME - Even when a radiation detector contacts a pipe arrangement or another member that is an object to be monitored, the damage of the detector is prevented without impairing the detection performance. An inside-tube-wall radioactive contamination monitor comprises: a rod-like light guide bar having a polygonal cross-section; a plurality of scintillators secured to the outer circumferential surface of the light guide bar; a net-like protective tube worn so as to cover the outer circumference of the scintillators with a space between the surfaces of the scintillators and the tube; and a guide portion attached to an end of the net-like protective tube, supporting an end of the light guide bar, and having a shape the diameter of which decreases as approaching the end. The monitor includes: a photoelectric conversion unit coupled to the base end of the net-like protective tube and incorporating a photoelectric conversion element; and a signal processing unit connected to the photoelectric conversion unit. | 11-24-2011 |
| 20110260068 | RADIOACTIVE CONTAMINATION MONITORING DEVICE AND MONITORING METHOD - Provided are a radioactive contamination monitoring device and a radioactive contamination monitoring method for enabling easy detection of radiation from an object to be monitored in a little surrounding space. The radioactive contamination monitoring device comprises a radiation detection unit, a photoelectric conversion unit for converting the light generated in the radiation detection unit to electricity, and a signal processing unit connected to the photoelectric conversion unit. The radiation detection unit includes a quadrangular prism-shaped light guide bar having a rectangular cross-section and a scintillator attached only to two adjacent side faces of the four side faces of the light guide bar. | 10-27-2011 |
| 20110023967 | TEMPORARY DRAINAGE SYSTEM AND TEMPORARY DRAINAGE METHOD - A temporary drainage system for draining rain water that flows into a floor under construction to an outside of a building during construction of a multiple-story building includes: a flexible drainage collection hose connected to a penetration hole formed in a floor slab of the floor under construction; a sand-settling vessel provided on a floor slab of a constructed floor of the building and connected to the drainage collection hose; a drainage pit provided on a lowest floor of the building to store drainage water discharged from the sand-settling vessel through a drainage hose; and a drainage pump provided in the drainage pit. The drainage water collected into the drainage pit is discharged to the outside of the building by an operation of the drainage pump. | 02-03-2011 |
| 20110010956 | BENCHMARK MARKING TOOL AND BENCHMARK MARKING METHOD - A benchmark marking tool includes a marking plate having an upper surface formed in a flat shape so as to mark a benchmark on the upper surface, a stud extending from a back surface of the upper surface of the marking plate and buried in a structure such as a floor of a building to fix the marking plate, and an outer peripheral flange provided around the marking plate and buried in a coating layer applied to the structure. The marking plate is provided such that the upper surface is located to be flush with or below an upper surface of the coating layer formed on the structure when the marking plate is located in the structure of the building. | 01-20-2011 |
