Title: Cascade type a/d converter
Inventor: YAMADA HARUYASU
IPC: H03M1/44
Filed: 1987-11-02
Abstract: PURPOSE:To decrease the number of elements greatly and to perform fast conversion by a low-speed device by providing a means which controls the polarity of the reference voltage of a succeeding stage with the polarity of an output voltage while sending the difference between an input signal and a weighted reference voltage to the succeeding stage. CONSTITUTION:An analog input voltage 3.5V is sampled by a sample holding circuit(S/H) 1-1 in a period T1 and held in a period T2. An operational amplifier(OP) 2-1 outputs the difference -0.5V between the voltage and reference voltage 4V. A comparator(C) 3-1 stores 0 in a latch circuit(L) 4-1 because the difference is negative. Data DMSB outputted to an output terminal 7-1 is 0. Further, -0.5V is held in the S/H 1-2 at the moment where a period T3 is entered and a switch 8-1 is switched to a side 2 at the same time, thereby outputting a reference voltage 2V. The OP 2-2 outputs a difference 1.5V. The C 3-2 outputs 1, the L 4-2 stores the 1 and data at a terminal 7-2 becomes 1. Similarly, the data 1 appears at a terminal 7-3. Consequently, the A/D conversion is performed.

IPC: F02M37/20
Filed: 1991-10-24
Abstract: PURPOSE:To prevent air pollution from being generated by maintaining the fuel supply device at an optimum condition of liquefication independently of the operational engine condition, and reducing production of the evaporation gas. CONSTITUTION:An evaporation gas which has been generated in a surplus fuel due to a rapid fuel pressure drop at a position directly beneath a fuel pressure regulating valve 4 enters from a fuel inlet 10 into a temporary residence vessel 7 in a gas/liquid mix phase condition in which the evaporation gas and a liquid gasoline exist in a mixed state. Of these two, the liquid gasoline is fed to a fuel tank 1 via a return pipe 6 while, on the other hand, the evaporation gas is caused to stay in the temporary residence vessel 7 and is liquefied. The liquid surface level of the surplus is sensed by a liquid level detector 12 and a control device 13 makes a feedback control of the discharge flow of a fuel pump 2. Accordingly, the liquid level in the temporary residence vessel 7 is maintained always at an optimum level, whereby a condition of gas/liquid separation is stably maintained. Thus, any evaporation gas can always be liquefied.

Abstract: PROBLEM TO BE SOLVED: To remove non-linear distortion by inputting a test signal to a non-linear system, measuring the transmission function of distortion, designing a Volterra filter in a frequency area from the measuring result and convolution-operating the Volterra filter in the frequency area. SOLUTION: A frame division part 12 divides signals from a signal source 1 by length N while they are partially overlapped so as to take them in. The divided signal of a time area is transformed into the signal of the frequency area in a Fourier transformation part 13. N-pieces of first coefficients in the frequency area and N×N- pieces of two-dimensional second coefficients in the frequency area are stored in storage parts 15 and 17. Thus, operation based on the first coefficients and the output signal of the Fourier transformatiout part 13 and operation based on the second coefficients and the output signal of the Fourier transformation part 13 are executed in operation parts 14, 16 and 18. Consequently, distortion from the output signal of the Fourier transformation part is removed.  An inverse Fourier transformation part 19 transforms the output signals of the operation parts 14, 16 and 18 into the signals of the time area, and a frame synthesis part 20 sequentially connects a part of the output signals of the inverse Fourier transformation part 19 and outputs them.

IPC: H04B17/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To find propagation conditions without using a special radio wave and a special receiver by using an existent radio wave. SOLUTION: An FFT(fast Fourier transform) computing element 1 converts a base-band signal to a frequency-axis signal through an FFT process and a pilot signal extractor 2 extracts only a pilot signal for amplitude and phase equalization which is arranged on the frequency axis from the frequency axis signal outputted from the FFT computing element 1. Then an amplitude and phase frequency characteristic detector 3 interpolates the pilot signal for amplitude and phase equalization and generates and outputs a frequency characteristic signal regarding the amplitude and phase. An IFFT(inverse fast Fourier transformation) computing element 4 finds the time-base signal of the output of the amplitude and phase frequency characteristic detector 3 and detects the electric energy to a delay time.  The electric energy which is thus detected is displayed as a delay profile on a display unit 5 in a predetermined form and saved in a data storage device 6 when necessary.
