Title: Arithmetic circuit for vector component
Inventor: SHIMIZU SUKENOBU
IPC: G06G7/22
Filed: 1979-01-24
Abstract: PURPOSE:To obtain the vector component of the input signal via the digital value by securing generation of the standard sine wave with the digital signal and then giving the n-cycle integration to the product of the standard sine wave and the input signal. CONSTITUTION:The one cycle of the reference signal of the sine wave is divided, and the waveheight value corresponding to each angle is memorized in memory part 4 in the form of the digital value. Then the analog input signal which is the measured signal from terminal 1 plus the digital signal read out of part 4 are supplied to D/A converter 3 to obtain the analog signal proportional to the product of the both. Then this output is supplied to double integration type A/D converter 7 to carry out the integration for one cycle via the integration gate signal sent from preset counter 5. Thus the digital value is delivered through terminal 18 for the preset phase component vector of the input signal. In such way, the vector component can be obtained with a high accuracy and through a simple circuit.

Title: Magnetic head
Inventor: WATANABE TOSHINORI
IPC: G11B5/235
Filed: 1992-01-16
Abstract: PURPOSE:To improve the breakage-resistant strength of a metal layer by a method wherein a metal magnetic layer is formed of an iron-based metal magnetic film which contains Al and the concentration of the component of the Al is set to be low on the side near a magnetic gap and to be high on the side near a magnetic core. CONSTITUTION:Metal magnetic layers 2a, 2b for a magnetic head are constituted of an Fe-Al-Ta-C-based magnetic film; the concentration of the Al component of the metal magnetic layers 2a, 2b on the side faced with magnetic cores 1a, 1b is set to be high, and the concentration of the Al component of the metal magnetic layers 2a, 2b on the side faced with the side of a magnetic gap is set to be low. When the magnetic films 2a, 2b having a grade in which the concentration of the Al component is gentle are used in this manner, it is possible to avoid a phenomenon that a recording magnetic field and a magnetic- field grade are saturated due to the low saturation flux density of the magnetic cores in conventional cases. Since a plurality of thin film layers exist, the recording magnetic field and the magnetic-field grade can be improved by effectively utilizing the high saturation flux density of the thin film layers near the magnetic gap.

Filed: 1978-01-25
Abstract: PURPOSE: To obtain a low-cost PWM modulator with a simple constitution by counting the input pulses with a fixed speed through the 1st and 2nd counters increasing or decreasing the number of the input pulse by the modulated pulse for the 2nd counter in order to alter the counting phase.  
     CONSTITUTION: The pulses given from pulse oscillator 11 are divided into 1/2 via divider circuit 12 and then supplied to 1st counter 21. At the same time, the divided pulses are supplied to 2nd counter via gate 35 and 41. When no modulation output exists, FF circuit 63 is set with 15 of the contents of counter 22 to give the rise time point of the PWM pulse. Circuit 63 is reset when the contents of counter 21 becomes O to give the fall time point. As the counting phase difference is constant between counter 21 and 22, the output of circuit 63 is turned to the PWM pulse which is modulated by a fixed amount. With application of the modulation input to increase or decrease the pulse duration, the counting action of counter 22 is advanced or delayed to increase or decrease the pulse duration of the output signal.

Abstract: PURPOSE: To control the adjusting force of a solenoid valve only by a valve spring irrespective of the injection pressure by operating a needle of an injection valve by an electromagnet to keep a pressure-balanced condition of the needle during the operation. CONSTITUTION: In a non-energized condition of an electromagnet 53, a valve spring 47 allows a valve needle 27 to abut on a needle valve seat 35, and the needle 27 is in the pressure-balanced condition so that the maximum pressure in the cylinder does not lift the valve needle 27 from the valve seat 35 by the spring bias of the valve spring 47. When the electromagnet 53 is energized, the valve needle 27 is driven together with a movable piece 55 toward the electromagnet 53 and is lifted from the needle valve seat 35. A pin of the valve needle 27 abuts on a valve ball 67 of a pressure-balancing valve 61 to open it. In the valve needle 27, the force balance is kept under the fuel pressure by the opened pressure-balancing valve 61. At the end of the injection process, the valve needle 27 is seated on the valve seat 35 by cutting off the energization to the electromagnet 53.
