Title: Fuel supply controller for internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02D41/04
Filed: 1989-02-16
Abstract: PURPOSE:To secure an operational chance of transient compensation value even at time of engine low speed as well as to avoid any lean misfire at the initial stage of acceleration by converting the time unit transient compensation value per constant time of a heat engine load parameter into the compensation value per constant crank angle on the basis of engine speed, and setting the final transient compensation value. CONSTITUTION:A time unit compensation value operational means operates a time unit transient compensation value on the basis of a variation in an engine load parameter per constant time. In brief, this time unit transient compensation value is of transient compensation value corresponding to a constant time operated on the basis of a variation in the engine load parameter per constant time. This transient compensation value operational means converts the time unit compensation value set in response to the constant time into the transient compensation value per constant crank angle on the basis of engine speed, and operates the final transient compensation value as a transient compensation value equivalent to the constant crank angle. On the basis of this transient compensation value, a transient compensation control means controls a fuel supply for compensation.

IPC: H04B10/2507
Filed: 1987-02-18
Abstract: PURPOSE:To facilitate the frequency stabilization of a coherent light source required for the frequency multiplex transmission with high accuracy by using each demultiplexed light being the result of demultiplexing a radiated light of a semiconductor laser or the like stimulated in the multi-mode as each carrier light in the frequency multiplex transmission. CONSTITUTION:A radiated light from a multi-mode stimulation semiconductor laser 12S is demultiplexed by a demultiplexer 14 and each demultiplexed light is subject to a desired modulation in a corresponding optical modulator. Each modulated optical signal is multiplexed by a multiplexer 18 and sent to the reception side R via an optical fiber M. In the frequency multiplex transmission, the radiated light is demultiplexed from the single multi-mode stimulation semiconductor laser 12S and its demultiplexed light is used to form a channel in the frequency multiplex transmission.

Title: Reaction force observer
Inventor: TOKUDA ATSUHIRO
IPC: H02P23/00
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To accurately estimate reaction force by subtracting the torque required for accelerating by a motor from the estimation output torque of the motor which is calculated, based on the sliding of the motor and the notch position of activation resistance, and by calculating the estimated reaction force. SOLUTION: An angular velocity ω of an induction motor is measured by a tachogenerator being directly connected to the induction motor. Estimation output torque Tm* of the induction motor is theoretically calculated as a function of sliding (s) and the notch position of a secondary resistance. The measured rotary angular velocity ω of the induction motor is inputted into the subtraction input of an angular velocity deviation calculating part 48, and the output of the angular velocity deviation calculation part 48 is fed back to the subtraction input of a torque deviation calculating part 45 via an observer gain part 49.  A reaction force observer has a function for determining L.Δω, so that estimated angular velocity ω* becomes equal to the measured angular velocity ω of the induction motor and the angular velocity deviation Δωbecomes 0, thus estimating the net reaction force applied from a load.

Abstract: PURPOSE:To reduce working time and to improve welding quality by setting beforehand the relative relation between a welding seam and an electron beam irradiation position outputted from a solid-state camera, and correcting the position of a beam device with the output signal of an image processor. CONSTITUTION:When light is cast from a light source 8 to the welding seam part of the work 2 and a solid state camera 7 is scanned on an observation plane, waveforms are obtained on a synchroscope 15.

When the work 2 starts traveling, and arrives at the irradiation position of an electron beam generator 6, the beam is irradiated thereto, and the camera 7 scans at prescribed intervals and outputs the above-mentioned signals. When a difference DELTAb between the seam position and an address (b) is produced, a command is emitted to a motor control power source 17 which runs motor 9 to move the position of a sliding seal mechanism 5. The traveling distance of the mechanism 5 is detected with a detector 12, and when it is confirmed that the mechanism has traveled the distance corresponding to the DELTAb, a stop command is fed to the power source 17.

Title: Electronic throttle control device for internal combustion engine
Inventor: KAMIO SHIGERU
IPC: F02D11/10
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To improve responsiveness of control of an electronic throttle. SOLUTION: When a throttle valve is not moved in the direction of a target throttle opening (hereinafter called 'during slowness in operation of a valve'), in spite of a deviation between a target throttle opening and an actual throttle opening exceeding a given value, an integrated item of PID control is increased through variation of offset processing and variation of an integrated gain. This constitution increases a controlled variable (a driving force of a throttle driving means) computed by means of a transmission function containing the integrated item. The driving force of a throttle driving means overcomes against a load available during slowness in operation of a valve and a throttle valve is rapidly started to move in the direction of a target throttle opening. Thereby, the occurrence of slowness in operation of the throttle valve is further reduced than that of a conventional type and responsiveness of throttle control is improved. This effect is produced in a way that a controlled variable is increased by other method than the increase of the integrated item.

Abstract: PURPOSE:To realize a smooth gate action and improve a gate margin by conforming the boundary between an ion implanted area and a non-ion implanted area with a transferring path of minor loop in the gate part that transfers or reproduces bubbles between a major line and minor loop. CONSTITUTION:A gate conductor 13 extends from a pickax pattern 12, a part of a major line, to the tip 10a of a minor loop 10, and its turning point is conformed with the boundary between the ion implanted part and the non-ion implanted part. There is no boundary between the non-ion implanted part and the ion implanted part on the route from the pickax pattern 12 to the transferring path of minor loop 10 connected through the gate conductor 13 excepting the transferring path of the minor loop. Accordingly, in transferring the bubble from the major line 11 to minor loop 10, there is no place that is apt to trap the bubble. As the boundary which is apt to trap the bubble is in the minor loop, the bubble becomes liable to be attracted by the minor loop.
