Title: Method for stripping slime
Inventor: KASHIWAGI SATOSHI
IPC: C02F1/00
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To eliminate a concern about carcinogenecity, to reduce toxicity to the human body and animals such as fish, and to improve safety by adding a specified aminopyrrodine into an aqueous system in which slime is generated. SOLUTION: The surface of a steel pipe is allowed to be covered with slime. To strip off the slime adherent to the surface, 1000 mg/liter of 1- aminopyrrolidine is added into test water, circulation is continued, and slime removing effects is observed from the turbidity of the test water and the appearance of the slime on the surface of the steel pipe 1. Part of the slime stripped off by the addition of 1-amibnopyrrolidine is dispersed as fine particles in the water to increase the turbidity. However, most of the stripped slime turns into a flock and is deposited on the bottom a circulation tank. In particular, 1- aminopyrrolidine is free from anxiety about carcinogenecity and is less toxic than hydrazine. In this way, slime adherent to a cooling water system can be stripped off effectively.

Title: Image processing device
Inventor: SHIMIZU MASAAKI
IPC: H04N1/413
Filed: 1984-12-25
Abstract: PURPOSE:To improve efficiency of transmission by making data transmission after compressing image data recurrently until efficiency of compression becomes highest. CONSTITUTION:The image data read from an image reading device 3 are compressed by a companding circuit 7, and the compressed data are compressed again by the companding circuit 7. Thus, compressed data once compressed are compressed recurrently using the companding circuit 7. While making compression recurrently, efficiency of compression becomes saturation after a certain number of times of compression. Accordingly, the image data compressed to a maximum value are sent out to the external together with the data that indicate the number of times of compression. When expanding data, compressed data are expanded by the companding circuit to correspond to the number of times of compression basing on data indicating number of times of compression. By this, way, original data can be restored in the image processing device of receiving side of the image data.

Title: Ground improvement method
Inventor: ISHII SABURO
IPC: E02D3/12
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To contrive to reduce treatment cost of removed earth and sand by excavating a proper-sized guide hole in a soil to be improved based on an earth drill method while injecting a stabilizing agent and placing a mixer in the guide hole into which a curing agent is injected, thereby forming an improved ground having a specified volume. SOLUTION: While a stabilizing liquid is being injected, a proper-sized guide hole 1 is excavated in a ground A to be improved by using an earth drill machine S and 30 to 50% of soil to be improved is removed, thereby forming a guide hole 1. Then, after the stabilizing liquid 2 is replaced with a curing agent, a tip agitation part 5 of a mixer is placed in the guide hole 1. While the curing agent 3 is being agitated with the ground A, the tip agitation part 5 is adapted to rise up to a specified elevation in the guide hole 1, thereby forming an improved ground having a specified volume. Differing from the case where the excavation stabilizing liquid comprises cement slurry, it is not specified as an industrial waste according to the related laws and regulations.  Since the earth and sand excavated together with the stabilizing liquid can be disposed of as an ordinal earth, this construction makes it possible to cut down the treatment cost of removed earth and sand dramatically.
