Title: Supercharged pressure controller
Inventor: MORIGUCHI KOUICHI
IPC: F02B37/12
Filed: 1982-05-08
Abstract: PURPOSE:To modify a maximum supercharged pressure in accordance with fuel and atmosphere conditions by varying the set load of a diaphragm spring inside the actuator of a waist gate valve. CONSTITUTION:At a high altitude location where the atmospheric pressure is low, a signal from a detective means such as an atmospheric pressure sensor is sent to a controller 15. The controller 15 changes over a three-way valve 14 to communicate a pipe passage 13 with a supply port 12 for feeding oil into a bellows 11. The communication between the pipe passage 13 and the supply port 12 is maintained for a period required for stretching the bellows as long as a supercharged pressure reaches its maximum optimum level matching the atmospheric pressure. After the above duration of the communication, the three- way valve 14 is changed over by the controller 15 to keep the oil pressure in the bellows 11. If the maximum supercharged pressure must be increased due to some charge of octane number of fuel or similar reason, an operator manually changes over a fuel change-over switch. A change-over signal is then generated to actuate the three-way valve 14.

Title: Method of repairing tuyere for bottom-blowing inert gas into converter
Inventor: SHIYOUJI SHIGEO
IPC: C21C5/48
Filed: 1981-05-21
Abstract: PURPOSE:To repair the titled tuyere at a high temperature, without detaching an old tuyere pipe from a furnace bottom, by handling the eroded old tuyere pipe as an insert hole for a new tuyere pipe, spreading amorphous refractory material over the periphery of the new tuyere pipe projecting above the old tuyere pipe, and drying and caking the amorphous refractory material. CONSTITUTION:A tuyere pipe 11 and a firebrick 12, which have been eroded by blowing inert gas into molten steel in a furnace to refine the molten steel, are repaired as follows: To the tuyere pipe 11, from which a plate 20 is detached, is inserted a new tuyere pipe 21 having diameter slightly smaller than the inner diameter D11 of the former tuyere pipe 11. The pipe 21 is fixed to the pipe 11 through flanges 19, 22. Amorphous refractory material 23 is spread over the periphery of the pipe 21 projecting above the pipe 11, i.e. the eroded firebrick 13, up to thickness until the top opening of the pipe 21 is exposed. The refractory material 23 is then dried and caked. According to this method, the tuyere can be repeatedly repaired and regenerated. Since repairing can be done at a high temperature, repairing work is speedy and simple. In its turn, the working ratio of the converter can be raised.

Title: System-interconnected inverter device
Inventor: ARINOBU HIRONORI
IPC: G01R19/165
Filed: 1995-04-03
Abstract: PURPOSE: To provide a system-interconnected inverter device which requires the less number of transformers when a voltage phase jump-off detecting method is used. CONSTITUTION: When a commercial power system 2 comes to an off-state, a transformer 13 takes out the AC output at an interconnection point 202. A phase comparing circuit 14 detects a phase difference between the AC output from the transformer 13 and the AC output from a voltage controlling and oscillating circuit 15 before the commercial power system 2 becomes the off- state. Immediately after the comercial power system 2 becomes the off-state, the AC output from the voltage controlling and oscillating circuit 15 is in phase with the commercial power system 2 before it becomes the off-state. Therefore, the comparison result of the phase comparing circuit 14 exceeds a specified value. As a result, a detecting circuit 16 generates a control signal. According to the control signal from the detecting circuit 16, a converting section 11 stops conversion of the DC output.

Filed: 1980-06-11
Abstract: PURPOSE: To control the number of pump units by calculating the number of operating units of water supply pumps according to the relation of the water level of the distributing reservoir in the second water supply system and the flow rate of the supplied water.  
     CONSTITUTION: A distributing reservoir 12 is formed on the consumption side of the second water supply system 4, and a supplied water flow rate detector 9 and a function generator 10 are arranged. When the flow rate of the first water supply system 3 varies, the flow rate of the second water supply system 4 varies. According to the relation of the output signals of the flow rate detector 9 and a distributing reservoir water level detector 13 and the output signal of the function generator 10, if the upper limit value < the measured value, the number of operating units is added, and if the upper limit value ≥ measured value ≥ the lower limit value, existing operation is continued, and if the lower limit value > the measured value, the number of operating units is reduced, thus the number of operating units of the water supply pumps 2 can be controlled. Accordingly, when the water supply amount of the second water supply system 4 and the water level of the distributing reservoir are within the ranges set, the operation state of the water supply pump is not changed, and the frequency of start can be reduced, and economical and effective operation can be obtained.
