Title: Gas security system
Inventor: MIZUTA TOSHIAKI
IPC: G08B21/10
Filed: 1992-12-28
Abstract: PURPOSE:To monitor the state of a gas leak alarm from the side of a gas meter by providing a circuit detecting the gas leak signal of the gas leak alarm and a signal sending circuit transferring the signal from the gas meter to the gas alarm in the gas meter. CONSTITUTION:An output from the control part 14 of the gas meter 2 is usually in a level H concerning both I and II. In this state, transistors Tr1, Tr2 and Tr3 is OFF and only Tr4 is ON so that a current loop is not formed and the state of the gas leak alarm can not be checked. In order to check the state of the gas leak alarm making the output I of the control part 14 into L makes the transistors Tr1 and Tr4 to be ON and current can be made to flow through Tr2 and a diode D1. Then, when the alarm 1 does not detect gas leakage, lead switch LS1 is OFF so that the potential of a point A is in a level H. When the alarm detects it, switch LS1 is ON so that the potential of the point A is in the level L and the state of the alarm can be detected from the side of the meter 2.

Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To simply prevent sand from flowing out on rain water by continuously scattering the sand having a specific grain size larger than that of the sand scattered at the competition portion of artificial turf near a side ditch on the artificial turf ground scattered with sand on the artificial turf. SOLUTION: A cushion layer 3 is laid on a foundation bed layer 2 made of asphalt, artificial turf 4 planted with synthetic fiber pile threads on a synthetic fiber ground fabric 41 to form turf leaves 42 is laid, sand 5 is scattered, and pressing force is applied to form this artificial turf ground 1. Sand 5A having a grain size larger than that of the sand 5 scattered at a competition portion is scattered near a side ditch 6 continuously to the sand 5. The average grain size of the sand 5A near the side ditch 6 is set to 0.4-2.3mm while the grain size of the sand 5 at the competition portion is 0.15-0.8mm. When rain water flows down, the sand 5 having the small grain size is floated and tends to flow out, however the sand 5A arrests the sand 5 and prevents its transit. The outflow of the sand 5 by rain water can be prevented.
