Abstract: PURPOSE:To raise the water shielding property of underground wall by a method in which a specific cut-off work is applied between the adjacent underground walls in such a way as to avoid the occurrence of weakened portions in the joints of the underground walls. CONSTITUTION:A shield 18 having a holder 20 having recessed portion with a soft part 22 on its periphery is erected into the end portion of the first hole 10 in such a way that the soft part 22 is positioned between the hole walls 26 and 27 in the widthwise direction of the hole 10, and then concrete is placed into the hole 10. After the concrete hardens, the shield 18 is pulled out of the hole 10 by leaving the soft part 22, and concrete is placed and hardened in the second hole 34 drilled for extending the hole 10 on the end side of the hole 10. Then, the boundary 40 of the soft part 22 of the surrounding concrete is drilled to form a hole 41 from the soft part 22 to its surrounding concrete under the guidance of a hole-expanding bit 42, and cement mortar M is packed into the hole 41. By this, the weakened portions, e.g., film of mud water as a stabilizer liquid, slime deposits, etc., can be cut off by the drilling using the bit 42.

Title: Suspension for internal use
Inventor: NAKANISHI SHIGEO
IPC: A61K9/10
Filed: 1988-03-22
Abstract: PURPOSE:To obtain a suspension for internal use prepared not so as to feel bitter taste in oral cavity, by absorbing a medicine having bitter taste into fine particles of iron exchange resin, suspending the medicine-absorbed resin into water and using the suspension as a medicine for internal use. CONSTITUTION:A medicine having bitter taste such as cimetizine or flufenamic acid and cation exchange resin (e.g., 'Amberlite IRP-64(R)') having 10-500Mn particle size are added to purified water and the mixture is stirred to absorb the medicine into the ion exchange resin. Then additive commonly used for suspension for internal use is as necessary added to the above-mentioned mixture to provide the aimed product. The aimed suspension is more readily administered by adding a sweetening agent such as sugar or D-sorbitol to the aimed product. According to a ratio of blend of the medicine having bitter taste with the ion exchange resin, the ion exchange resin is normally used in an amount slightly more than hat of the medicine.
