Abstract: PURPOSE: To enable to detect data-bit with a broad margin sufficiently, by detecting a clock signal including the variation of rotation of a magnetic disc and controlling the time width of a data window signal with the output of signal difference between the signal and the time width of reference oscillation.  
     CONSTITUTION: A clock signal 11 including variance of rotation from a photoelectric element detecting the rotating speed of a magnetic disc is input to a phase detector 40 via an amplifier 10 and frequency dividing circuit 20. The phase detector 40 compares the signal with the pulse width of the reference signal from a timer 30, and the differential signal is given to a voltage controlled oscillator 60 as DC voltage via an LLPF50. The oscillator 60 feeds a clock N5 of the frequency corresponding to the input voltage to a counter 70. The counter 70 is set at the leading of a data window signal DW to count up the N5, and when it reaches the set value, a signal N6 is fed to a D type FF80, a reproduction data RD is received, and the DW is on via an inverter G1. Thus, the data bit can be detected with a sufficiently broad margin.

Title: Electronic controller for internal-combustion engine
Inventor: ISHIGAMI KAZUHIRO
IPC: F02D41/22
Filed: 1983-07-15
Abstract: PURPOSE:To exactly control an engine when a crankshaft angle sensor is in abnormal condition, by using a signal from an intake pulsation detector instead of that from the crankshaft angle sensor found in abnormal condition by a crankshaft angle sensor signal abnormality detector, to regulate a control equipment. CONSTITUTION:To detect whether a crankshaft angle sensor 1 is in abnormal condition or not, the rotational number of an engine is calculated from a 1 deg. signal and then from a 180 deg. signal. If both the rotational number values calculated from these signals have a difference of 20% or more, the sensor 1 is judged to be in abnormal condition. Supposing the engine has four cylinders, two intakes are performed during one rotation of the crankshaft of the engine or there are two intake pulsations during one rotation. The period T of the intake pulsation is detected to calculate the rotational number of the engine through the output signal of an air flow meter 14. Since the maximum value of the output voltage of the air flow meter 14 corresponds to the end of the intake process of the cylinder during the period T immediately before the maximum value of the output voltage, the angle of the crankshaft can be determined by calculating the angles at which a power transistor 21 is turned off and on after the maximum value of the output voltage of the air flow meter. Control is performed on the basis of both the determined angles.

Filed: 1986-06-02
Abstract: PURPOSE:To attain the sufficient recording sensitivity and a reproducing output with a sufficiently large level even with miniaturization by providing a soft magnetic film with a high permeability on the surface of a core member of a supporting member. CONSTITUTION:The soft magnetic film 6 is formed on the surface of the core member 2 of the supporting member 1 and the film 6 and the core member 2 are stuck by an adhesive layer 5, and a main magnetic pole winding 4 is applied to the core member 2. That is, the soft magnetic film 6 is provided to the entire surface at the side of the core member 2 of the supporting member 1 to increase the area of the main magnetic pole film 3 opposed to the core member 2 effectively thereby reducing the magnetic resistance 3, then the magnetic flux caused from the core member 2 is focused efficiently to the film 3, and vice versa. Thus, the magnetic coupling between the main magnetic pole film 3 and the core member 2 is intensified, and even if the perpendicular magnetic recording head is miniaturized in a degree that, e.g., the magnetic pole length is nearly the same as the thickness of the adhesive layer 5, the excellent recording sensitivity and a sufficiently large reproducing output are obtained.
