IPC: F02D41/34
Filed: 1979-07-17
Abstract: PURPOSE: To improve engine accelerating performance and to prevent generation of noxious gases at the rapid acceleration of engine, by providing a rapid acceleration correcting means which produces correcting pulses for accomplishing injection of such an amount of fuel as required by engine when the throttle valve opening speed has exceeded a predetermined value.  
     CONSTITUTION: An electronically controlled fuel injection system is constituted by main control unit 1 which produces injection pulses for accomplishing injection of such an amount of fuel meeting with the operational conditions of engine such as the rate of intakeair flow at a predetermined time during the cycle of engine operation using pulses synchronous with the engine speed as standard pulses, and rapid acceleration correcting means 2. The rapid acceleration correcting means 2 is constituted by sensor 3 for detecting the opening of throttle valve, differentiating circuit 4 for producing a throttle valve opening speed signal on the basis of output a of the sensor 3, comparison circuit 5 which compares output b of the circuit 4 with a reference voltage and produces output c in case that output b is greater than the reference voltage, and control circuit 6 for producing correcting pulses d in synchronism with ignition signals I in response to output c.

Title: Cdma mobile communication receiver
Inventor: IMAIZUMI MASARU
IPC: H04B1/707
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To enhance the reception quality by allowing a mobile communication receiver adopting the time division multiple access (CDMA) method to conduct synchronization acquisition and tracing in response to fluctuation in a selected path timing and a reception SIR. SOLUTION: A mobile communication receiver is provided with a delay profile calculation means 103 that applies moving average to a correlation in response to a moving average time designated by a moving mean time control means 105 to calculate a delayed profile, and the moving average time control means 105 that measures timing fluctuation of a selected path so as to decide the moving average time. The moving average time means 105 decreases the moving average time when the timing fluctuation in the selected path is high and increases when the moving average time is small. Since a path movement follows a rapid timing fluctuation of the selected path due to a high speed movement of the communication equipment by controlling the moving average time of the delay profile in this way, the synchronization acquisition and tracing performance is improved and the reception quality is enhanced.

Title: Steam supply equipment for geothermal turbine
Inventor: TAKAHASHI MASAHIKO
IPC: F03G4/00
Filed: 1981-06-11
Abstract: PURPOSE:To enable the operation of a mixed-pressure geothermal turbine with only primary steam and prevent the abnormality of the turbine blades, by providing a shutoff valve in a by-pass line which connects the primary and secondary steam lines of the turbine to each other. CONSTITUTION:Geothermal steam is divided into primary steam and hot water by a steam and water separator 2. The hot water is changed into secondary steam by a flasher 7. The secondary steam enters into the halfway stage of a turbine 6. To operate the turbine 6 with only the primary steam because of the defectiveness of the flasher 7, a stop valve 15 is entirely closed and another stop valve 14 is opened to supply some primary steam to a secondary steam line 10 so that both the primary steam and secondary steam flow into the turbine 6. As a result, the initial cost of the turbine 6 is prevented from increasing, and the operation of the turbine is continued with only the primary steam so that the turbine blades are not exposed to abnormalities.

Title: Electric signal formation device
Inventor: ARAN JIEI WAANAA JIYUNIA
IPC: G01R29/12
Filed: 1993-04-16
Abstract: PURPOSE: To effectively and accurately generate a signal indicative of a static electricity on an insulating surface by converting a current signal proportional to the difference between a surface potential and a high voltage power supply potential into a low voltage signal and outputting the low voltage signal. CONSTITUTION: A detected high voltage is fed through an input line 20 to a circuit. A current flowing through a source follower, comprising a high voltage resistor R1 and an NMOSFETQ1 produces a potential difference between the gate of the FETQ1 and a high voltage power supply. A current i1 of a transistor Q3 follows up the current of a transistor Q2 which is equal to the current of the FETQ1 , and the current i2 of a high voltage resistor R2 represents the voltage of the high voltage power supply.  Consequently, the difference between the currents i1 , i2 provides an accurate input voltage to the line 20 and since it is fed from an amplifier 22 through a resistor Rfb, a high input impedance required for an electrostatic voltmeter is sustained, and the FETQ1 and a mirror system Q2 -Q3 convert a high voltage input into a low voltage output, without requiring any low voltage power supply having voltage substantially equal to the measuring potential.
