Filed: 1985-05-20
Abstract: PURPOSE:To detect the end of a web of a winding roll, by opposing a pair of contact elements at the periphery of the winding roll, and furnishing a detector to detect the relative displacement between the contact elements. CONSTITUTION:The end of a web WE first passes a roller 1L of the contact rollers 1L and 1R, that is, the web end WE passes the position of the roller 1L, and comes between the rollers 1L and 1R. Therefore, at the beginning, only the roller 1L and a vertical rod 3L go down, but the roller 1R and a vertical rod 3R don't. Consequently, the rollers 1L and 1R, and, the rods 3L and 3R are displaced relatively, and, a limit switch 7 of the rod 3L contacts the tip of the rod 3R. In that, the switch 7 acts and the relative displacement of the rollers 1L and 1R can be detected. Therefore, the web end WE of the winding roller R can be detected by he switch 7.

Title: Method for repair construction of foundation pile
Inventor: IWATA ISAO
IPC: E02D5/64
Filed: 1995-05-02
Abstract: PURPOSE: To reduce loss in usage, and to conduct repair having high reliability by injecting a high-viscosity organic or inorganic repair material into a crack section through a pit drilled to a foundation pile and injecting a low-viscosity organic or inorganic repair material from other pits. CONSTITUTION: A pit 5 is drilled, and a mouth-root member 6 is fixed. When a vapor phase section 10a is supplied with high-pressure gas, a high-viscosity resin liquid 9 of 5000cp or more in a sealed vessel 10 receives pushing, and is injected and filled into the pit 5 from a filler port 7. Consequently, the resin liquid 9 is infected into the cracks of a foundation pile 1. Cement milk having grain size of 10-20μm is used as another repair material. A low-viscosity resin liquid of 100-1500cp is injected similarly through another pit drilled in parallel with the pit 5 after curing solidifying. As a result, the cracks not yet filled are filled by injection. Accordingly, uniform filling by injection is attained while loss in the usage of the repair materials can be reduced, and the object of the repair reproduction of the foundation pile can be attained at low cost with high reliability.
