Title: Power-controlling pwm signal generator
Inventor: NAKAMURA KAZUTO
IPC: H02M7/48
Filed: 1987-06-24
Abstract: PURPOSE:To prevent the breakdown of element by providing first and second comparators at respective positive and negative symmetric levels in tie vicinity of the upper and lower peak points out of triangular wave signals and by forbidding an ignition signal in the vicinity of said peak values. CONSTITUTION:A PWM signal generator generates a PWM control signal from ROM 12; and is composed of counter 11, D/A converter 14, interpolation circuit 21, PWM modulator 22, triangular wave generator 23, comparators 24-25, rise/fall detector 32, forced set/reset circuit 37, flip-flop 40 and others. Then, a reference voltage is given to comparators 24-25 so that minute PWM modulation signals are generated when control signals a little lower and higher than the peak values of triangular wave signals and respectively having the same absolute value exceed said level. Thus, because an ignition signal is forbidden in the vicinity of the peak values of said triangular waves, the phase lag of a pulse does not occur to enable a PWM control with high accuracy.

Abstract: PROBLEM TO BE SOLVED: To facilitated adjusting of a shade of a woodgrain pattern or the like, and obtain depth or stereoscopic appearance by forming an interdiffusion layer by heat treatment between a thermoplastic base material and a thermoplastic pattern material. SOLUTION: A recess 1a is formed on a surface of a thermoplastic base material (a base material) 1, and a thermoplastic pattern material (a pattern material) 2 having a different color from the base material 1 is embedded therein. The embedded pattern material 2 and the base material 1 are treated by heat for gradually melting, and interdiffusion generates between the base material 1 and the pattern material 2, and a interdiffusion phase F is formed. Thereby, a deep part of the recess 1a has small amount of diffusion to the surface of the base material 1 thereunder and develops a color of the pattern material 2 stronger, and a shallow part develops a color of the base material 1 thereunder stronger and a color of the pattern layer 2 weaker, so that a shaded color is obtained.  Thus, by the change of an outline/depth distribution of the recess 1a, an optional pattern can be formed and an adjusting of shade (forming of flat grain or the like) can be performed.

As a result, the jammed paper can be removed easily. The oblique shift of the paper 6 is detected by the oblique shift sensor 19 to deliver the signal. Then the eccentric cams 17 and 17' provided with a shift of 180° given to the phase have turns according to the output signal in the same direction and by a fixed angle. As a result, arms 11 and 11' rock in the opposite directions to each other, and the spring force is controlled for the springs 16 and 16' to give a fine control to the pressure between the rollers 7 and 8. Thus the oblique shift of the recording paper is corrected easily.

Title: Fuel injection quantity controller for internal combustion engine and control method thereof
Inventor: DATE TOSHIAKI
IPC: F02D45/00
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To reduce all the hydrocarbon delivery quantity of total hydrocarbon(THC) of a catalyst non-active condition which purifying capacity of a catalyst is low by multiplying a correction coefficient by a fuel corrective amount according to the catalyst active condition to collect the fuel corrective amount by the fuel correcting means, in the case where the catalyst active condition is not complete and an acceleration opening is increased. SOLUTION: In the case where a catalyst active condition is a non active and an acceleration opening has being accelerated, a fuel corrective amount is reduced. For example, a correction coefficient 0 is multiplied by the fuel corrective amount to make zero, and a fuel sticking correction is inhibited. An acceleration opening is increased at a time t1, and it is decreased again at a time t2 after holding a constant time. The fuel corrective amount is reduced when a catalyst is activated, smaller than an air-fuel ratio 14.7 when fuel sticking correction is carried out at the time of acceleration, and then, fuel sticking correction is carried out. As a result, acceleration is suppressed. At the time of deceleration, a fuel injection amount Qout is reduced, a fuel sticking amount stuck on an inner wall of an intake pipe is suppressed, and rich of acceleration is reduced.  It is thus possible to reduce a discharge quantity of THC when the catalyst is not activated.
