Title: Tape reel
Inventor: IWAHASHI YUJI
IPC: G11B23/087
Filed: 1993-03-04
Abstract: PURPOSE:To eliminate the winding unevenness of a tape and to prevent edge damages by inclining the inner surface of the lower reel flange of the tape reel low toward an outer peripheral side and inclining a tape winding surface to this inner surface roughly 90 degrees. CONSTITUTION:The tape winding surface 3 of a tape reel 1 is set with its inclining angle theta 8' to 15' at an upper reel flange 5 side so as to increase the diameter of the winding surface 3. Then, the inner surface of a lower reel flange 4 is inclined roughly 90 degrees against the inclination of the winding surface 3. Therefore, since the lower edge of the tape to be wound on the winding surface 3 is wound while being controlled along the inner surface 4a of the lower flange 4, the winding unevenness of the tape is eliminated and uniformly wound. Thus, even when the tape is changed and down due to vibration and impact added to the tape reel, the swelling of the tape is eliminated and edge damage is prevented.

Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To effect secure and efficient intake of water by excavating an injection well along a water resource and injecting the water in the water resource in an underground aquifer through the injecting well. SOLUTION: A stratum having a high permeability coefficient is detected and injection wells 1 are excavated along an agricultural water channel A to let water flow into the agricultural water channel A throughout the year. Water discharged to the channel A is led to a filter apparatus 7 through an aqueduct 6 to remove dirt and then, infected into the infection wells 1. This water is injected from holes 4 of an injection strainer 5 of a well pipe 3 into an aquifer W. The injected water volume is monitored and measured by a simple device 13 in the infection well 1, and water is continuously infected as long as water does not overflow from a pipe 12 extended to the ground level. In this way, since sufficient water is held in the aquifer W even when spring water Ws is exhausted, water can be appropriately drawn up from a well 21 and used.  Accordingly, secure and efficient intake of water can be effected while conserving the natural environment.
