摘要： PURPOSE: To expel an unnecessary cleaning medium from the center of a container, then reduce the consumption of the cleaning medium or the volume of generated cleaning medium waste, and improve the cleaning performance by injecting the cleaning medium into a cleaning space sectioned by the container and a space forming member. CONSTITUTION: An inner lid 2 with a cleaning nozzle 19 is introduced, with a spacer 15 bracing the lid 2, into the interior of a container 1. In addition, at the bottom of the container 1, a pipe 13 for extracting a cleaning medium and a pipe 12 for injecting an air for stirring are arranged. Further, a pump 6 for circulating the cleaning medium is installed on a cleaning medium circulation line 14. A liquid 4 such as water is poured into the interior of the inner lid 2, if necessary, so that the liquid can balance the buoyancy of the inner lid 2 in the container 1. The flow of the cleaning medium in the container 1 is caused by the circulation of the cleaning medium by a pump 6, the consequent bleeding of the cleaning medium from a cleaning nozzle 19, or the injection of a compressed air from the pipe 12. After that, the cleaning medium is extracted from the pipe 13.

摘要： PURPOSE:To prevent adhering of solidying matter paste at the tip of an injection pipe by sharpening the tip of the injection pipe and using a material with large surface tension. CONSTITUTION:An injection pipe 7 is constituted of an outside cylinder steel pipe 7a and a cylinder teflon pipe 7b using teflon with large surface tension. By giving inclination of ca. 40 degree from the side and ca. 45 degree from the thickness direction to the tip of the teflon pipe 7b, the adhering of the solidifying matter paste to the tip of the pipe 7 is prevented during injecting the solidifying matter paste from the mixing tank 4 to the solidification vessel. Therefore, such a problem is avoided that the pipe 7 is blocked by the adhering layer at the tip of the pipe 7 accompanying the operation of the solidification device and the injection of the solidifying matter paste becomes eventually impossible.

摘要： PURPOSE:To attain coincidence control between an instruction and data cache with the small amount of a hardware by detecting whether the data is stored in the other cache memory or not only when the data to be required to a cache memory is not present thereon, and making the data invalid when this data is present in the other cache memory. CONSTITUTION:A cache data identifying means 130 is provided to identify all information existing in an instruction and the data cache memory 152. When the data to be required to one cache is not present thereon, the required data is read out from a main memory 200 and newly registered and the cache data identifying means 130 detects whether the relevant data is present in another cache 122 or not. When this data is present in the other cache, this data is made to be invalid. Then, exclusive control is executed to inhibit the same data to be registered to the instruction cache 122 and the data cache 152. Thus, without providing an instruction change buffer, competition between instruction and data storage can be controlled in an instruction and data separating cache memory.
