Title: Road side-ditch for rainwater and infiltrating means therefor
Inventor: OIDE AYAKO
IPC: E03F5/04
Filed: 2001-06-01
Abstract: PROBLEM TO BE SOLVED: To solve such an urgent problem that rainwater in torrential rain flows straight into a sewer pipe in a low-lying section even by about 1-2 m as places such as a field, a wood and a gravel road heretofore naturally infiltrating the rainwater into the ground are made into sites for building and paved one after another and that the rainwater flows back to a manhole of a house toilet together with domestic waste water to spout a yellow jet of water to cause a floor more than knee-deep in a moment, flooding a house up to or above the floor. SOLUTION: The lowest part concrete of a conventional road side-ditch of L-shaped cross section for rainwater is removed, and steel frame members are arranged and supported therein and fixed at both ends with concrete to construct this new type side-ditch. Rainwater flows from a number of large clearances of the steel frame members to crushed stones laid under a paved road and further to soil underneath from time to time to repeat infiltration. The rainwater insufficiently infiltrating at first and flowing into a sewer pipe, gradually creates by itself places to infiltrate from each part of the side-ditch constructed long and narrow, and flows down to a water stratum.

Title: Diaphragm pump
Inventor: KONISHI YOSHIAKI
IPC: F04B43/067
Filed: 2001-07-18
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of air bubbles in operating liquid of a hydraulic diaphragm pump and to improve the volume efficiency of a pump. SOLUTION: A reservoir chamber 38 which is approximately sealed is provided on a back surface side of a piston 26. The air bubbles generated in a hydraulic driving chamber 36 filled with operating liquid for transmitting motion of the piston 26 to a diaphragm 34 are exhausted to the reservoir chamber 38 through an air vent passage 42 provided with an air vent valve 26. The reservoir chamber 38 is controlled to have pressure approximately under atmospheric pressure and is in a low pressure state by the motion of the piston 25 and a function of an exhaust valve 50. Thereby, re-dissolution of gas to the operating liquid is prevented. The operating liquid replenished from the reservoir chamber 38 to the hydraulic driving chamber 36 includes less dissolved gas and thus the generation of the air bubbles is suppressed.
