Title: Active filter device
Inventor: OKAWA KATSUMI
IPC: G05F1/10
Filed: 1991-04-19
Abstract: PURPOSE:To securely detect a current which flows to a reactor irrelevantly to variation in temperature by detecting the current which flows to the reactor by a detecting circuit equipped with a metallic resistance body and applying the detection output to a control circuit. CONSTITUTION:A damper diode D5 charges the charging voltage of the reactor L in a capacitor Cd. A control circuit COM controls the switching of a transistor Q0. The rectifying circuit composed of diodes D1-D4 converts an AC source voltage into a rectified AC voltage and then the TR Q0 supplies a coil current to the reactor L intermittently. At this time, the detecting circuit DEC equipped with the metallic resistance body which is low in resistance temperature coefficient(TCR) as a detection resistance detects the current flowing to the reactor L directly. Consequently, the current which flows to the reactor L can securely be detected irrelevantly to the variation in temperature. Further, auxiliary winding can be omitted and the TR Q0 can be controlled with the detection output of a detecting circuit DEC through control pulses phi of the control circuit COM.

Title: Servo motor speed control method
Inventor: KACHI MITSUYASU
IPC: G05B19/416
Filed: 1992-04-09
Abstract: PURPOSE:To deal with such a low speed at which even a signal pulse is not received in a single sampling period. CONSTITUTION:A speed (M/T) is obtained by dividing the number M of position feedback pulses by the time T required for counting these pulses. When a speed (1/a) where the speed (M/T) is shown in the number M per sampling period (ITv) is lower than '1', a part of the total of '1-1/a' is defined as a feedback speed for each of subsequent sampling times. Thus it is possible to obtain an accurate locus with a smooth operation and even with an interpolated operation of two axes or more.

Title: Method of feedback controlling air-fuel ratio of internal-combustion engine
Inventor: WAZAKI YOSHIO
IPC: F02D41/00
Filed: 1984-05-02
Abstract: PURPOSE:To improve the performance of an engine, by reducing delay of follow- up control to a desired air-fuel ratio by starting feedback control of the air-fuel ratio using the mean value of air-fuel ratio correction factors determined for each operational range of the engine as an initial value. CONSTITUTION:If judgement is made at a step 31 that the engine operation is in its idling range, a correction factor Ko2 is set at a mean value KREFO at a step 40. In starting feedback control of the air-fuel ratio when the engine operation is in its idling range, the mean value KREFO is used as the initial value of the correction factor Ko2. Here, if the answer of the step 31 is NO, the initial value of the correction factor Ko2 at the time of starting feedback control is set at a mean value KREF1 calculated for each range of feedback operation. By employing such a method, it is enabled to reduce delay of follow-up control to a desired air-fuel ratio and to thereby improve the response characteristics of the engine in its idling operational range.

Abstract: PURPOSE: To make precision judgement of fuel properties and to judge the change of fuel properties at an early stage by detecting rotational fluctuation by each combustion stroke, adding the detected data to a smaller specific number of times and also to a larger specific number of times, and judging the fuel properties on the basis of each added data. CONSTITUTION: While an engine is in operation, first, rotational fluctuation by each combustion stroke is detected at a control unit 2 from the output of a crank angle sensor 4 and then the detected data is added to a smaller specific number of times and also to a larger specific number of times. Fuel properties are judged on the basis of the added data and the fuel injection quantity is corrected in accordance with the learning value of the fuel properties. The fuel properties judgement finds the difference between a stability index for detecting fuel and a stability comparison value as a stability margin portion and judges it as heavy fuel when the stability margin portion is below the specific value and as light fuel when it is above the specific value. It also judges that it has changed to a heavy fuel from the stability index for detecting sudden change of the fuel properties.
