Abstract: PURPOSE: To make easy the arrangement, maintenance and inspection of engine, by the correction of duty ratio at maximum and minimum flow so that it is not at 100% and 10% and fixing it to the limit value if the corrected value is in excess of the limit value set.  
     CONSTITUTION: In the ON-OFF electromagnetic valve supplying pulse signal to the ON-OFF electromagnetic valve and controlling the flow based on the ON-OFF ratio, the amount of exhaust return of the automobile engine 11 is controlled 20 with the ON-OFF electromagnetic valve 10. This control circuit 20 selects the pattern of exhaust return set according to the state of operation in advance and determines the basic duty given to the electromagnetic valve 10. Thus, the duty ratio is corrected so that it is not 100% and 10% at maximum and minimum flow, and if the corrected value is in excess of the set limit value, programming is made so as to fix to the limit value. Thus, the operating condition of the electromagnetic valve 10 and the control circuit 20 can simply be discriminated for case of engine arrangement, maintenance and inspection.

Title: Magnetic field application device for optical disk device
Inventor: SHIO YUTAKA
IPC: G11B11/10
Filed: 1990-02-19
Abstract: PURPOSE:To correct an impression magnetic field to that within a specified range by providing a magnet which is make opposite to a recording type optical disk surface and made freely rotatable around the rotary shaft parallel to the disk surface, and setting the rotary shaft to be eccentric in a state where an eccentricity quantity can freely be adjusted to a magnetic pole. CONSTITUTION:The rotary shaft 11 of the magnet 8 is set to be eccentric as against the magnetic pole and an N-pole-side is set to be far from the magneto-optical disk DI1 surface from the center of the magnet 8. The strength of the magnetic field impressed from the magnet 8 on the DI1 surface is weak at the time of recording and it becomes strong at the time of elimination as shown in a broken line C. A leakage magnetic field 10 owing to the actuator 5 of an optical pickup 3 operates so that the strength of the magnetic field is increased at the time of recording and it is decreased at the time of elimination when the polarity is set to be an N-pole. Thus, the eccentricity quantity of the shaft 11 is set to be freely adjustable structure and a distance between DI1 surface and the magnetic pole is suitably set. Thus, the leakage magnetic field 10 is compensation-cancelled and it can be corrected to the impression magnetic field stored within the specified range at the time of recording and elimination as shown as a solid line D on the DI1 surface.

Title: Brake force control device for vehicle
Inventor: NAMINO ATSUSHI
IPC: B60T8/1755
Filed: 1991-02-08
Abstract: PURPOSE:To assist a driver during braking by vehicle behavior control as lowering of deceleration is suppressed during brake wherein a difference between brake forces on both sides is produced owing to slip control (ABS). CONSTITUTION:The controller of a brake force control system calculates brake liquid pressure difference DELTAP1 to be set through vehicle behavior control and a pressure reduction amount, being a command value during ABS control, by using respective control rules. When the latter control is operated and a difference deltaP between command values on both sides is produced, a calculating value DELTAP1 of the former control is corrected at S202 and S205 by means of a result of comparison between the DELTAP1 value and the deltaP value. When the brake liquid pressure difference DELTAP1 is lower than the difference deltaP between command values both sides, 4 P. is equal to 0, and vehicle behavior control is prohibited. When it is higher than the difference deltaP between command values both sides, vehicle behavior control is executed by means of a difference (DELTAP1 -deltaP) between  P1 and deltaP.
