Patent JP-H02190604-A (JP)
Title: Hydraulic circuit for pilot system
Inventor: YOSHIMATSU HIDEAKI
IPC: F15B11/08
Filed: 1989-01-18
Abstract: PURPOSE:To prevent the response delay of a pilot system by letting return oil from a relief valve flow into the absorbing side of a pump through a by pass oil passage when the oil temperature is less than the set value, and if more than the set value, switching a change-over means to let the return oil flow into a tank. CONSTITUTION:When an engine is started, oil from a controlling pump 2 is relieved from a relief valve 4 and rises in temperature by exothermicity generated by this relief. In this case, if the oil temperature is less than the set value, return oil is not returned to a tank 1, but absorbed into a by pass oil passage 42 and further into a pump 2 through a set pressure variable check valve 6, and the oil temperature rises acceleratingly by this circulation. On the other hand, if the oil temperature is more than the set value, the check valve 6 is closed by the expansion of a temperature sensing spring 62, and the return oil is thereby returned to the tank 1. The oil temperature rise in a pilot system can be thus efficiently achieved, so that response delay can be prevented even in the cold.

Title: Method for blowing flux into blast furnace
Inventor: KISHIMOTO SUMIYUKI
IPC: C21B5/00
Filed: 1990-01-19
Abstract: PURPOSE:To prevent the clogging of piping for blowing with flux by mixing pulverized coal to the flux at the specific ratio at the time of blowing MgO, CaO series flux from a tuyere for producing low Si molten iron in a blast furnace. CONSTITUTION:In order to lower the Si content in the molten iron tapped during operating the blast furnace, the MgO, CaO based flux is blown from the tuyere and reacted with SiO2 in molten slag in the vicinity of the blowing tuyere, and by making the stable slag, activity of SiO2 is reduced to prevent the increase of Si in the molten iron with the reduction of SiO2. In this case, in order to prevent the clogging of the flux blowing pipe with the MgO, CaO based flux having high m.p., the pulverized coal is mixed with the flux at 0.07-0.4 ratio. The low Si molten iron can stably be produced with the molten material of flux without clogging of the piping.

Title: Method for inspecting leakage from underground tank, communicating pipe or the like in gasoline station
Inventor: MAESHIBA SOUZABUROU
IPC: G01M3/32
Filed: 1983-01-25
Abstract: PURPOSE:To enable simple and accurate leakage detection of gasoline and to enable searching of leakage from an underground tank or any place of a communicating pipe by releasing air from the inside of the underground tank and the communicating pipe. CONSTITUTION:A vacuum pump 6 is operated to release air from the inside of an underground tank 1 and communicating pipes 2-4 and to evacuate gradually the inside thereof. The operation of the pump 6 is stopped in the specified evacuation state and at the point of this time, whether the specified evacuation state is maintained in the tank 1 and the communicating pipes or not is inspected. A decrease in the reduced pressure is indicative of leakage of the air in either of the underground tank or the communicating pipes. The inspection of the leaking point of the pipes is accomplished by moving a balloon body for closing by shifting the position of the balloon at every specified interval from the top to base end of the pipe and making the pressure inspection. If there is any point where the reduced pressure decreases, the place where the decrease in the reduced pressure arises is known nearly exactly and the exact leaking position of the leaking pipe is known.

Title: Servo type gas controlling valve
Inventor: KOJIMA TADASHI
IPC: F16K31/12
Filed: 1981-01-28
Abstract: PURPOSE:To enable to change the set pressure of an outlet passage at will by a method wherein the opening area of a working gas passage which leads the gas pressure to a main diaphragm chamber. CONSTITUTION:A switching valve 15 opens a small valve seat 13 and in turn closes a by pass valve 14. Because working gas is led through a passage 17 to the main diaphragm chamber 8, the pressure within the main diaphragm chamber 8 ascends with working gas and exceeds the pressure within the outlet passage 3, resulting for a main diaphragm 9 in generating the force intending to open a main valve 4 against a spring 7. When the force generated at the main diaphragm 9 exceeds the force of the spring 7, the main valve 4 starts to open, allowing to fuel gas to start to flow through a port 5 to the outlet passage 3. Simultaneously the pressure within the outlet passage 3 starts to ascend and feeds-back through a passage 26 to a feedback diaphragm 19.
