Title: Magneto-optical head
Inventor: MURATA SUSUMU
IPC: G11B5/02
Filed: 1988-12-12
Abstract: PURPOSE:To prevent the occurrence of a leaked magnetic flux and to improve magnetic field generating efficiency by fixing a magnetic body plate to a magnetic pole face opposite to a recording medium of a magnetic field generating coil with which a magneto-optical head applies a magnetic field to the recording medium. CONSTITUTION:A light beam B is converged by an objective lens 2 and the magnetized film of a magneto-optical medium 11 is irradiated with the beam B. Consequently, the temperature of the irradiated part rises and the coercive force of the magnetized film is reduced. Meanwhile, power is supplied to a magnetic field generating coil 3 so that a magnetic flux in the direction opposite to the magnetization of the magnetized film is generated, and the part irradiated with the beam B is magnetized. A magnetic body plate 5 is fixed to the magnetic pole face under the coil 3. Thus, the occurrence of an unnecessary leaked magnetic flux is prevented and the strength of the magnetic field is increased. Consequently, the current flowing to the coil is reduced and the head is miniaturized. Further, the heat radiation effect is improved by the magnetic body plate and magnetism is shielded to prevent the degradation of the servo performance of an actuator.

Title: Limiter gain control circuit
Inventor: RI DOUBUN
IPC: H03G3/10
Filed: 1989-12-01
Abstract: PURPOSE:To change the gain linearly between -ndB and ndB by adopting a current control circuit including 1st and 2nd differential amplifier circuits so as to prevent a current zero to a limiter circuit and selecting a current ratio of four constant current sources as specified. CONSTITUTION:A variable voltage source VA is adjusted to vary voltage difference  VA between bases of TRs Q7-Q10. When the difference  VA is zero, currents from constant current sources I1-I4 become collector currents. A current to a limiter 1 is expressed as 1A=I2+I4 by a current mirror comprising TRs Q13, Q14 and the relation of (3/8)I0+(1/8)I0=(1/2)I0 exists by the setting. In the case of VA=VMAX, TRs Q8, Q9 are turned on and TRs Q7, Q10 are turned off, and the current flowing to the TR Q8 is expressed as I1+I2=(5/8)I0+(3/8)I0= I0=IA. In the case of  VA=-VMAX, the TRs Q7, Q10 are turned on, and the TRs Q8, Q9 are turned off and the current flowing to the TR Q10 is expressed as I3+I4=(1/4)I0=IA. Thus, the current supplied to the limiter 1 is varied from 1/2 to twice with respect to  VA=0 as a reference by the adjustment of the variable voltage source VA and the fact of IA=0 does not take place.

IPC: F02D41/06
Filed: 1989-12-05
Abstract: PURPOSE:To prevent lowering of the rotating speed of an engine and the stall of the engine at start so as to enhance the starting performance of the engine by stopping correction of the amount of fuel flowing on the wall surface of the engine until a predetermined period of time elapses from the start of cranking. CONSTITUTION:A controller 1 computers the amount of intake air according to the flow passage cross section of an air intake passage and an engine rotating speed output from a rotating speed sensor 2, and then retrieves the amount of fuel attached to the wall surface of the engine according to the amount of intake air and computes the difference in the amount of fuel between the routine of this time and the previous routine. The difference in the amount of fuel is multiplied by a constant and a transient coefficient of correction is computed as a corrected amount of fuel flowing on the wall surface. The difference in the amount of fuel is set to zero until a predetermined period of time elapses after a starter switch 5 is turned on, so as to stop correction of the amount of fuel flowing on the wall surface. The most suitable amount of fuel supplied at the start of the engine is thus secured to prevent lowering of the rotating speed of the engine and the stall of the engine to enhance the starting performance of the engine.
