IPC: G11B5/09
Filed: 1986-04-04
Abstract: PURPOSE:To obtain a reproduced signal of high precision by subtracting an integral signal from a differential signal of the detection signal of a magnetic head to obtain zero crossing points which are not shifted and converting them to a data string. CONSTITUTION:A detection signal A from a magnetic induction type magnetic head 1 is amplified by an amplifier 2 and is applied to a differentiation circuit 4 and an integration circuit 6'. An output signal B from the circuit 4 is allowed to pass a low frequency restoring circuit 9 and a filter 10, and a corrected signal E is applied to an adder circuit 11. The signal E is added to an output signal C' from the circuit 6' by the adder circuit 11 to generate a false complete integral signal E, and this signal E is applied to a subtracter, circuit 7. An integral signal C'' is subtracted from the output signal B of the circuit 4 by the subtracter circuit 7, and the output is applied to a zero cross detecting circuit 5 through a filter. The integral signal is corrected and the false complete integral signal is obtained from the corrected signal in this manner to obtain zero crossing points which are not shifted, and they are converted to a data string, and the reproduced signal of high precision is outputted.

Title: Fuel control device of internal-combustion engine
Inventor: UCHINAMI MASANOBU
IPC: F02D41/04
Filed: 1985-04-09
Abstract: PURPOSE:To stably control an engine speed when an engine is in idle operation and a vehicle is in low speed running, by inhibiting a correction of fuel through a quantity of change or its rate of an engine parameter when the engine is placed in a condition near the idle operation and not in no-load operation. CONSTITUTION:An arithmetic unit 8, if it detects by an output signal of a throttle opening sensor and a pressure sensor 2 or an engine speed sensor 3 that an engine is in an idle condition or in the vicinity of the idle condition, prevents the engine from a change of its speed by correcting a basic injection quantity of fuel through a quantity of change or its rate of an engine parameter like the negative pressure of an intake pipe. However, on the basis of a decision signal from an no load detecting circuit inputting a signal from a clutch switch 6 and a transmission position switch 7, when the engine is not in a no-load condition, the arithmetic unit, inhibiting said correction, prevents the engine from inducing a change of its speed when a vehicle is in low speed running (in idle inertia operation) by correcting a surplus amount of fuel.

Title: Manual steering controller for carrier vehicle
Inventor: OMORI KATSUYOSHI
IPC: G05D1/02
Filed: 1988-03-30
Abstract: PURPOSE:To facilitate the manual steering operation by controlling the driving speed of a carrier vehicle based on the difference of rotational speeds between right and left drive wheels. CONSTITUTION:A difference speed arithmetic circuit 6 obtains a difference speed from the rotational speeds detected by the right and left speed sensors 7 and 8. A speed command circuit 5 changes the speed command signal received from a drive motor 3 based on the difference speed value obtained by the circuit 6 and reduces the driving speed of a carrier vehicle. As a result, the driving speed of the vehicle is slowed down as the rotational radius of the drive wheel is decreased. Thus the manual steering operation is facilitated.
