Title: Supply of circulating water to steam pipe of exhaust gas economizer
Inventor: IMAI SHIRO
IPC: F22B1/18
Filed: 1988-01-22
Abstract: PURPOSE:To prevent a steam pipe from being melted, by a method wherein the temperatures of high-pressure and low-pressure steam pipes are detected, and when one of the detected temperatures exceeds a predetermined temperature, the quantity of circulating water supplied is increased, and an auxiliary water-supplying pump is operated to supply water contained in a cascade tank into a high-pressure steam separator. CONSTITUTION:The temperatures of high-pressure and low-pressure steam pipes 2, 9 are detected by temperature sensors 13, 14 attached to the steam pipes. When one of the detected temperatures exceeds a predetermined temperature, auxiliary pumps 4B, 11B for high-pressure end low-pressure steam separators 3, 10 are operated to increase the quantities of circulating water supplied to the steam pipes 2, 9, and simultaneously, an auxiliary water supplying pump 6B is operated to supply water contained in a cascade tank 7 into the high-pressure steam separator 3 through a water-supplying pipe 16 provided with a solenoid valve 15. Thus, the quantities of circulating water passed through the steam pipes 2, 9 are maintained appropriately. When the temperatures of the steam pipes 2, 9 are lowered, the operations of the auxiliary pumps 4B, 11B, 6B are stopped.

Abstract: PURPOSE:To perform the proper air-fuel ratio control by exercising the feedback so that an area ratio of the output of an O2 sensor at the upper and lower sides of a slice level of the O2 sensor is kept at a fixed value and reflecting the responding time of the sensor on the area ratio. CONSTITUTION:An electronic controller is composed of a CPU1, a ROM2, a RAM3, an input port 4, an output port 5, a data bus 6, etc. and the O2 sensor 7, a water temperature sensor 8, a throttle sensor 9 and a sensor 10 of the suction pipe negative pressure or the like are connected with the input port 4 via an A/D converter 11 and an REF signal of the number of revolutions of an engine or the like and a signal from a crank angle sensor are taken in as the digital signals. The O2 sensor indicates a fluctuation wave near to a rectangular wave when the air-fuel ratio is shaken with the stoichiometry as a center, but actually, it becomes a broken waveform. Then, the area ratio of the output of the O2 sensor at the upper and lower sides of the slice level is kept at the fixed value and the area ratio is changed corresponding to the deterioration of the O2 sensor with the lapse of time and the slice level is changed to compensate the deterioration of the O2 sensor.

Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To detect the pressure of air in a tire by excluding the effects of disturbance from road surfaces and the like. SOLUTION: An electronic control device (ECU) 5 operates the wheel speeds based on the detected signals of wheel speed sensors 2a-2d, performs frequency analysis (FET operation) for the wheel speeds and obtains the signal strength for every frequency. Furthermore, the number of times when the wheel speeds are located in the wheel-speed band (Vα-Vβ) where the resonant vibration is liable to occur is counted. When the number of times is less than a specified number of times, moving average processing is performed by using all results of the frequency analysis extracted until that time. When the number of times is larger than the specified number of times, the moving average processing is performed by using only the result of the frequency analysis when the wheel speed V is located Vα-Vβ.  Then, the resonant frequency is obtained within the specified frequency range so as to set the resonant vibration of the tire appearing in the vicinity of 40Hz as the object of detection. The air pressures in the tires 1a-1d and operated from the above described resonant frequency.

Filed: 1990-01-23
Abstract: PURPOSE:To enable uniform exhaust and reduce the dispersion of characteristics in a wafer by providing the exhaust pipe of an exhaust device with a branch pipe, and constituting the branch pipe so as to open at the predetermine pressure of the exhaust. CONSTITUTION:A process gas is made to flow through one tube 10 among a plurality of process tubes 10, and no process gas is made to flow through other tubes 10, with a lid body 14 closed. In this state, the flowrate of the process gas flowing for the exhaust capacity of an exhaust fan 20, is small and, therefore, the inside of an exhaust tube 22 falls in a substantially negative pressure condition. As a result, the differential pressure acting on a movable valve 42 becomes larger than the weight thereof, and the valve 42 comes to be substantially afloat. Consequently, the atmosphere enters the exhaust tube 22 via a recessed part and pressure in the exhaust tube 22 is always maintained at the predetermined level. Desired pressure can be obtained via the change of the weight of the valve 42 per unit area.
