Title: Control device for engine
Inventor: SAITO YOICHI
IPC: F02D21/08
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To attain improvement of fuel consumption and reduction of exhaust emission by exhaust gas recirculation, while ensuring purge ability of a large amount of vaporized fuel mixture, by preventing an influence due to the recirculation to an intake system of exhaust gas, in the case of purging vaporized fuel generated in a fuel tank. SOLUTION: Just after starting a purge, when estimation of evaporation concentration is not completed, by stopping EGR also low suppressing a purge factor, in almost a total operating region, the fixed purge factor is ensured, also over rich air/fuel ratio by vaporized fuel of high concentration just after starting the purge is prevented. Thereafter, during the time evaporation concentration exceeds a preset value, an EGR factor and purge factor are suppressed, a region fixing the purge factor is spread, when the evaporation concentration is decreased to the preset value or less to decrease an influence as a disturbance, both the purge/EGR factors are increased, while ensuring a large amount of evaporation purge factor, improvement of fuel consumption by EGR and a reducing effect of exhaust emission are drawn out to a maximum limit.

Abstract: PURPOSE:To obtain dots of a fluorescent substance as desired in size by providing a mechanism which moves the height of a slit up and down in accordance with the rotating angle of a luminescent tube. CONSTITUTION:A light source section 1 includes a lamp house section 100 equipped with an ultra high pressure mercury lamp 104 and a drive section 105 which rotates the lamp house section 100 around a pipe shaft 6. And the lamp house section 100 is equipped with a mechanism which permits the height of a slit 22 to be moved up and down in accordance with the rotating angle of the mercury lamp 104 driven by the drive section 105 by means of a slide shaft 102 and a guide shaft 103 connected with the aforesaid shaft with an eccentric cam 101 rotated, which is fixed onto a motor 106. The ultra high pressure lamp 104 is therefore rotated around the pipe shaft 6 even if there exists the local difference in the luminous energy of the luminescent section of the ultra high pressure mercury lamp 104 of the light source section 1. By this constitution, the dot of a fluorescent substance can thereby be obtained as desired in size without the local change in the size of the dot of the fluorescent substance on both surfaces.

Title: Linear acceleration/deceleration circuit
Inventor: NOMURA YASUO
IPC: G05B19/416
Filed: 1986-11-13
Abstract: PURPOSE:To realize a high-speed and smooth linear acceleration/deceleration action by applying the hardware processing to a linear acceleration/deceleration pattern which is supplied to a binary rate multiplier BRM. CONSTITUTION:When an acceleration command is given from a CPU 18, the conditions of an AND circuit 16 are satisfied and therefore an acceleration pulse is supplied to the UP input of an up/down counter 12. The counter 12 counts up its value for each input of the acceleration pulse and the rate input of a BRM 13 also increases in response to the acceleration pulse. Therefore the speed pulse output is also increased successively to realize a linear accelerating action. When a target speed is obtained during acceleration, an upper limit speed detecting circuit 15 works and a signal is inverted by a NOT circuit 17. This inverted signal is supplied to the circuit 16. Thus the input of acceleration pulse is stopped to the counter 12 and the output of the counter 12 is fixed. As a result, the frequency of the speed pulse output is kept constant to attain a constant speed operation. So is with a deceleration command as well.

Filed: 1987-10-29
Abstract: PURPOSE:To decrease the difference between a permanent magnet attraction force and a spring force and provide high speed driving, by placing a Piezoelectric element in parallel to the permanent magnet with respect to the bias direction of a plate spring. CONSTITUTION:When not in printing operation, an armature 4 is attracted to the face end of a core 3 by a permanent magnet 7 to bias the tongue piece of a plate spring 2 toward the core. During printing operation, a voltage is applied to a piezoelectric element 15 to separate the core 3 from the armature 4, increase the bias amount of the plate spring 2, and decrease the difference between the magnet attraction force and spring force. Now, the armature 4 can be easily separated from the core 3. A gap 16 is produced between the magnet 7 and a yoke 9 by the deformation if the piezoelectric element 15 to increase the reluctance of a magnetic force of the magnet 7. This further decreases the difference between the attraction and spring forces, providing a high speed driving of a printhead.
