Title: Water theft preventing fire hydrant
IPC: E03B9/02
Filed: 1992-03-11
Abstract: PURPOSE:To prevent water from being wrongfully stolen for the purpose other than fire fighting. CONSTITUTION:When a valve stem 3 fitted to a valve element 2 in a valve box 1 is rotated, the valve element 2 is vertically moved to open or close a valve. A gear 21 is fixed to the upper end of the valve stem 3, and a pinion 51 engaged with the gear 21 is coupled with the valve box 1 so that the pinion 51 is horizontally rotated together with a handle 4 protruded at the upper end and a pinion shaft 52 below it to be engaged with or disengaged from the gear 21. As the pinion 51 is normally disengaged from the gear 21, the valve is not opened even if the handle 4 is rotated by an irrelevant person on the ground, and no water flows out. When the pinion 51 and the gear 21 are engaged in one touch and the handle 4 is rotated in case of a fire, water is immediately discharged. A fire hydrant can be used only for a fire fighting activity in the area where a water theft is an everyday affair.

Filed: 1981-06-10
Abstract: PURPOSE:To enable precise detection of quick acceleration or quick deceleration by a simple circuit, by providing two systems of speed-voltage transducing circuits detecting an engine speed and by providing a difference in the respective integration time constant. CONSTITUTION:A pulse signal of a pickup 4 fitted to an engine is transformed into a differential signal by a rotation detecting unit 20 and further shaped into a rectangular-wave pulse for a defenite time by a monostable multivibrator 21. This rectangular-wave pulse is integrated by an integration circuit 22 and subjected to voltage conversion, and then is doubly integrated by a deceleration detecting circuit 23. The capacitor C1 of the circuit 23 being made to have small capacity and the capacitor C2 thereof large capacity, an output voltage at a point A is made to follow up immediately a quick change speed, while an output voltage at a point B is made change with a delay for a definite time. By setting the voltage at the point B to be made lower than the voltage at the point A by a resistance partical voltage, the B-point voltage is raised temporarily only at the time of quick deceleration and thus the quick deceleration is detected.

Title: Water-proof floor installation structure
Inventor: TOSAKA TOSHIAKI
IPC: E03C1/20
Filed: 1988-04-11
Abstract: PURPOSE:To reduce the weight of a base as well as shorten the installing time of floor by a method in which a base of adjustable height is set on the backs of the crossing four corner walls of a water-proof floor, the upper edges of them are connected with metal connectors, and a swivel leg is inserted into a level regulating leg and hardened. CONSTITUTION:The upper ends of four bases 6 are connected with metal connectors 9 to form a rectangular base 6, and the base 6 is set on a designated floor and centering of the whole circumference is made by using the regulating leg 10 of the base 6. Dimensions from the back of wall-fitting face 4 to the lower end of a level regulating leg 5 is equalized with the height of the base 6 by the leg 5 on the back of the water-proof floor bottom. The four wall-fitting faces are placed on the base 6. A swivel cylindrical leg 7 with a bottom filled with a hardening synthetic resin 8 is inserted into the leg 5 and erectly set on floor. The level regulation can thus be made for the water-proof floor only by the leg 10 of the base 6 but not for the leg 5 of the floor 1. The installing time can thus be shortened.

Filed: 1994-04-26
Abstract: PURPOSE:To prevent electric shock and damage by locating a front end face in a position lower than an insulating post, thereby causing the area of a mating opening to be substantially reduced by the insulating post, and covering the front end face with an insulating cover member. CONSTITUTION:A side wall 26 extends from the peripheral edge of a bottom wall 20 in such a way as to surround an insulating post 24, and has a front end face 26a formed along the direction of engaging. An engaging opening 28 surrounded by the front end face 26a is formed, and since the front end face 26a is located in a position lower than the insulating post 24, the end 24a of the insulating post 24 is located above the engaging opening 28. The front end face 26a of the side wall 26 is covered with an insulating cover member 30. Since part of the engaging opening 28 is occupied by the insulating post 24, the area of the engaging opening 28 is reduced so much that foreign matter such as fingers and tools cannot enter through the engaging opening. Moreover, the front end face 26a is covered with the insulating cover member 30, so foreign matter such as fingers and tools cannot make contact with a socket contact 14.
