Title: Fuel injection control unit for internal combustion engine
Inventor: YOSHIOKA MAMORU
IPC: F02D41/04
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection control unit for an internal combustion engine such that it can prevent deterioration of drivability due to significant change of air-fuel ratio of the internal combustion engine, while suppressing unstable fuel injection as much as possible. SOLUTION: While an engine is operated in a light-load range such as idling, a required amount of fuel injection is small. So, if breakdown or the like of a pressure regulator 48 occurs in such a state, a calculated final fuel injection period can be less than a predetermined value a. On the other hand, while the engine is operated in a range with higher load than idling operation, a required amount of fuel injection is large. So, the final fuel injection period cannot be less than the predetermined value a. When the final fuel injection period is less than the predetermined value a, it is maintained to be the predetermined value a by a lower limit protection. Thus, the air-fuel ratio of air-fuel mixture becomes richer than the stoichiometry.  Moreover, the predetermined value a set by the lower limit protection is reduced to a predetermined value b so as to settle the air-fuel ratio from rich to stoichiometric.

Filed: 1988-09-06
Abstract: PURPOSE:To prevent the alteration of the frequency of a first high frequency clock when the frequency of a sampling clock is dropped by the width power of two by outputting the clock to a counter part included in a first frequency- dividing means by means of a repeating two-frequency-dividing. CONSTITUTION:A phase difference detection means 4 detects the phase difference of demodulation data of a bit rate (f) and the sampling clock, and the first frequency-dividing means 5 calculates a frequency-dividing rate for making to the phase difference. A second clock similar to a first sampling clock obtained by frequency-dividing the first high frequency clock of an input frequency f0 by the calculated frequency-dividing rate and synchronizing with demodulation data, and the sampling clock which a second high frequency clock of a frequency 2<-m>f0 generates at the time of input is generated. A differential means 6 selects bit rate (f) from the second clock from the means 5 and differentiates the rise and fall of the clocks by the first high frequency clock. A second frequency-dividing means 7 2<-m>-frequency-divides the first high frequency clock under the control of the output of the means 6, and transmits the high frequency clock of 2<-m>f0 which is synchronized with the sampling clock. Thus, correspondence is attained without altering the frequency.

Filed: 1985-10-07
Abstract: PURPOSE:To eliminate the excessive supply or dripping of paint and to facilitate the control of a film thickness, by forming such a roller structure that only the part pressed against a surface to be painted of a coating strip is successively impregnated with paint. CONSTITUTION:When liquid paint is sent to a hollow shaft 2 under pressure from a paint pump, the paint passes through the emitting ports 3 of the hollow shaft 2 and the through-hole 6 of a support cylinder 5 and further passes through the through-holes 18 of a spring cylinder 17 to fill a cylindrical roller 8. When the cylindrical roller 8 is tumbled on a surface (a) to be painted in this state, in the part pressed to the surface (a) to be painted, a coating strip 20 pushes the leading end of a valve body 15 and pushes up the valve body 15 against the elastic force of the spring cylinder 17 to open exudation ports 13 to impregnate the coating strip with the paint through the exudation ports 13. When the tumbling of the roller 8 advances and the coating strip 20 is separated from the surface (a) to be coated, the exudation holes 13 are closed and the opening/closing of the exudation ports by desired pressing force is repeated to apply paint with a predetermined film thickness.

Abstract: PURPOSE:To prevent photographic paper from snaking even when its width is different by providing a control means which moves a flange for photographic paper width-directional guidance, rotatable coaxially with a winding drum, axially according to the width size of the paper. CONSTITUTION:The male screw 72 of a rotating shaft 70 rotated by a driving motor moves a coupling plate 64 axially together with two driving shafts 58 and 56. Consequently, a disk 44 is moved to the right and left. A roller 48 provided to the disk 44, therefore, moves the flange 54 in the axial direction of the winding drum 20 through a flange boss 50. Thus, the flange 54 is moved according to the width of a roll part 24A loaded on the winding drum 20, and the breadthwise center part of the photographic paper 24 is aligned with the optical axis of printing of a printing part. A winding drum 22 arranged below the winding drum 20 has similar structure. Thus, even when photographic paper of different width size is used, the photographic paper is prevented from snaking.

Title: Torque ripple eliminator of reluctance-type motor
Inventor: BAN ITSUKI
IPC: H02P6/16
Filed: 1990-08-28
Abstract: PURPOSE:To eliminate torque ripple and improve characteristics by a method wherein data written in a selected ROM are read and converted into analog signals and a current applied to a motor is controlled by chopper control. CONSTITUTION:When a motor 3 makes one turn, a reset signal is inputted to a R-ROM writer circuit 51 from a shaft encoder 6 through a lead N. At that time, the values of the outputs of a dividing circuit 54 at the respective turning positions in the one turn of the motor 3 are divided minutely into digital signals synchronized with the turning positions and stored in a ROM 51a. The value of Fn(theta) stored in the ROM 51a is read and a current applied to the motor is controlled in accordance with the read value to obtain a required torque free from torque ripple. If Fn(theta) is multiplied by a constant K1 which controls the applied current and the applied current is made to correspond to the multiplied value, the applied current In is expressed by a formula K1Fn(theta). The torque Tn of every one turn is expressed by a formula K.K1In and, as the current In is a constant current, torque ripple is eliminated.
