Title: Delay equalization circuit
Inventor: ISHIZUKA TSUKASA
IPC: H04B3/14
Filed: 1994-07-29
Abstract: PURPOSE:To obtain a desired delay equalization characteristic only with adjustment by selecting a delay with respect to a desired frequency with a fast Fourier transformation device and a delay circuit and converting the delay into time series data by a fast inverse Fourier transformation device. CONSTITUTION:An A/D converter 1 limits a band of an analog input signal to be fS/2 [Hz] or below and converts it into a digital signal based on a sampling frequency (clock) fS [Hz]. Time series data converted into the digital signal are subject to frequency analysis by an n-point FFT 2. N-sets of outputs from the FFT 2 are given to n-sets of delay circuits 3-5. Each delay circuit is a k-stages of shift register and a delay of kXn/fS [sec] at maximum is optionally selected for each n/fS [sec] through the changeover of the switch. The n-point IFT 6 converts each of frequency data of the delay circuits 3-5 into time series data. A D/A converter 7 converts the time series data into an analog signal and a builtin filter is used to interpolate the signal. Thus, a desired delay time characteristic is obtained without calculation of a complicated inverse transfer function.

Title: Hydraulic braking device for automobile
Inventor: NOMURA YOSHIHISA
IPC: B60T8/1761
Filed: 1983-09-27
Abstract: PURPOSE:To make such an on-off valve as having once been closed during one braking operation so as not to cause it to reopen, by installing a slider, contacting a ball of the on-off valve, in a piston opening or closing the valve via a spring, whiel setting the on-off valve that has once closed the spring, to be weaker in force than that required for reopening. CONSTITUTION:In time of skidding, a selector valve 74 is selected in its directional control by a computer 96, and a piston 42 of a hydraulic control valve 22 is driven and controlled, closing an on-off valve 41, while capacity in a chamber 44 of the hydraulic control valve 22 if made to grow large whereby hydraulic pressure in a wheel cylinder 16 gets dropped down to some extent. When the on- off valve 41 is once closed, the piston 42 moves to the right and even if it tries to open the on-off valve 41, only a spring 56 contracts in size and a slider 50 moves back, that is, the valve 41 will not be opened at all because a pressure differential acting on a ball 40 and energizing force in a spring 38 are all set to be large than the energizing force of the spring 56. Therefore, in this brake operation, hydraulic pressure in the wheel cylinder 16 is controlled by only increase or decrease in the capacity of the chamber 44 by means of movement in the piston 42, thus a brake feeling becomes improved so better.
