Title: Idle rotational speed control method
Inventor: SOGAWA TAKAYUKI
IPC: F02D41/00
Filed: 1986-04-25
Abstract: PURPOSE:To shorten a time during which the idle rational speed upon starting is stabilized, by leaning a feed-back duty value obtained from feed-back in a memory table using the temperature of water as a parameter. CONSTITUTION:A basic duty value previously stored in memory using the temperature of cooling water as a parameter is read out (step S102). When feed- back between the engine rotational speed and a desired rotational speed is stabilized (step S105), a new feed-back duty value is stored in a leaning table (S106). Thus, it is possible to shorten a time during which the idle rotational speed upon starting is stabilized to aim at enhancing the starting ability of the engine.

Title: Chopper type amplifier circuit
Inventor: KOKUBO MASARU
IPC: H03F3/38
Filed: 1983-06-03
Abstract: PURPOSE:To decrease the effect of a stray capacitance of a feedback circuit by providing capacitors for chopper separately depending on the direction of a charge current flowing to them. CONSTITUTION:The capacitors Co1, Co2 for chopper are provided separately depending on the direction of the charging current, and only the Co1 is connected when an output of an operational amplifier A goes positive and only the Co2 is connected respectively when the output goes to negative. Then the Co1 is charged positive at all times and the Co2 is charged negative at all times respectively when viewed from the output side of the amplifier A. As a result, the stray capacitance Cs being parasitic to the Co1, Co2 respectively is charged positive or negative only at all times. Thus the feedback effect repeating charge/ discharge to the stray capacitance Cs alternately is not caused and the feedback effect is not almost subjected to the disturbance by the stray capacitance Cs. Then the effect caused by the stray capacitance Cs being parasitic to the feedback circuit is eliminated.

Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for sharply reducing the torque ripple of a motor. SOLUTION: This system produces the table of motor current control values as the function of the motor operation angle, and produces a torque request signal which shows the desired value of the torque supplied by a motor 22, and produces a torque command signal which has a value related functionally to the torque request signal and a feed forward torque signal. This monitors the motor operation angle, and energizes the motor 22, using the current control value from the table, answering the torque command signal, and measures the quantity of torque ripple generated in the motor 22, and applies filter processing to the measured torque ripple, using a time range filter, and produces the torque ripple signal being time-range-filtered. Next, this uses the average time range filter processed torque ripple signal where the average of the signals is taken and further filter processing is applied, as a feed forward torque signal.

Title: Detection of water leakage in blasting tuyere
Inventor: MATSUMOTO SHUNJI
IPC: C21B7/24
Filed: 1995-03-30
Abstract: PURPOSE: To reduce the equipment cost by judging whether the difference between each actually measured value and a preset prescribed reference value drainage quantity from each blasting tuyere has varied a prescribed value or larger, or not. CONSTITUTION: In the first step 11, a water flow rate reference value and a setting value in each tuyere Tn is read in. Progressing to the following step 12, an actual measured value of drainage quantity by the flow meter of a drainage pipe in the tuyere is read in. Progressing to the following step 13, the reference value is substracted from the actual measured value of the drainage quantity to calculate the flow rate difference. In the step 14, the adding value to the flow rate difference is calculated. In the step 15, whether the absolute value of the flow rate difference is a threshold value or more, is judged. In the step 16, at the time of judging what the absolute value of the flow rate difference added value is less than the threshold value, it is judged that the water leakage is developed, and a water leakage alarm is sounded.  By this method, the suitable reference value is set.

Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To provide an interference wave level detection circuit detecting the level of a narrow band interference wave by connecting power detectors to an input side and an output side and obtaining the level of the narrow band infrequence wave containing in an inputted signal. SOLUTION: A signal inputted from an input terminal 2 is amplified by an amplification rate variable amplifier 4 and is divided into two by a signal distributor 21. One is inputted an static wave filter 22 and the other is inputted to a power detector 24. The signal outputted from the static magnetic wave filter 22 is divided into two by a signal distributor 23 and one signal is outputted from an output terminal 7 and other is inputted to a power detector 25. The outputs of the power detectors 24 and 25 are inputted to a power difference detector 26. The power difference detector 26 detects the difference of power detected by the two power detectors 24 and 25, namely, power limited by the static magnetic wave filter 22 among the power of a narrow band interference wave. Thus, the level of the narrow band interference wave can be detected in an interference wave level defector 29.

Title: Dry etching method
Inventor: TAKADA CHIYUUICHI
IPC: H01L21/28
Filed: 1979-07-31
Abstract: PURPOSE: To easily prevent the production of undercuts, in dry etching of a metal film, by performing water treatment on the way of etching thereby forming an oxide film.  
     CONSTITUTION: At the time of forming the electrodes and wirings of semiconductor devices by dry etching a metal film, the undercuts produced at that time are easily prevented and fine patterns are easily obtained. For example, an aluminum film 2 of about 1μm thick is formed on a substrate 1 by a vapor deposition method. The film formed by coating photoresist thereon is subjected to pattern exposing and developing, whereby a photoresist mask 3 is formed. Next, the aluminum film 2 is etched by a dry etching method to 0.1μm thickness. This is taken out and is subjected to water treatment by rinsing or boiling in the water, whereby an oxide film 4 is formed on the aluminum film 2 surface. If the aluminum film is etched again, only the aluminum film is removed from the main surface because the side faces are lower in etching rate than the main surface.
