Title: Method of controlling failured atmospheric pressure sensor in electronic control fuel supply apparatus
Inventor: TAKAHASHI SHIYUNJI
IPC: F02D41/24
Filed: 1983-08-04
Abstract: PURPOSE:To ensure high safety travelling without abnormally lean air fuel ratio by replacing the output signal of atmospheric pressure sensor with a predetermined output signal when the atmospheric pressure sensor is failured. CONSTITUTION:An electronic control fuel supply unit controls air flow to control air fuel ratio on the basis of various information of an engine including an atmospheric pressure sensor. When any failure of the atmospheric pressure sensor is detected, a signal So corresponding to the output signal of the atmospheric pressure sensor in a certain atmospheric pressure Po is set and employed in place of the output signal S of the failured atmospheric pressure sensor to control air fuel ratio on the basis of this signal So. Thus, since supercharging condition is not obtained when the atmospheric pressure sensor is failured, high safety travelling is ensured without any abnormally lean air fuel ratio.

Title: Remote controller for air conditioning machine
Inventor: MOCHIZUKI SHIGENOBU
IPC: F24F11/02
Filed: 1988-06-10
Abstract: PURPOSE:To eliminate external noise and to obtain a sure control signal by transmitting a signal modulated with the same signal of which frequency is different with shifting timing, comparing the respective signals demodulated at a receiving side and using the coincidence signal. CONSTITUTION:A CPU 1 in remote control generates a data signal corresponding to an SW input or a temperature input. A first and second transmitting parts 2 and 3 emit with a signal to which the carrier of frequency f2 and f3 is modulated with the data signal. Since a timing adjusting part 5 is inserted between a clock signal generator 4 and the transmitting part 3, the signal of the transmitting parts 2 and 3 shifts by 1/2 clock portion. A first and second receiving parts 7 and 8 of an air conditioning machine main body detect the data signal of carrier frequency f2 and f3 from the transmitting parts 2 and 3. Since a timing adjusting part 9 is inserted between the clock signal generator 6 and the receiving part 7, the output signals of the receiving parts 7 and 8 synchronize. A coincidence circuit 10 outputs H when the both of the receiving parts 7 and 8 are H. Then, noise fN is eliminated.

Title: Analog transmission path controller
Inventor: MORIMOTO TAKESHI
IPC: H04N5/91
Filed: 1991-06-14
Abstract: PURPOSE:To avoid causing a trouble due to quantization distortion by providing a reference signal superposing means, a comparing means and a characteristic changing means, controlling a characteristic changing means based on a comparison result, and correcting deviation of a transmission path at dubbing. CONSTITUTION:A video signal from a reproductive digital processing circuit 5 is added for calculation to a basic signal 25 including an amplitude, a DC electric potential, a frequency characteristic and a sampling phase by a superposing means 24. Then the result is outputted from a terminal 26 through a D/A converter 6 and an output circuit 7. The result is received by a terminal 27 and then via an A/D converter 10, an amplitude of a digital signal is controlled by a characteristic variable converter 100. The number of bits of the output is decreased by a rounding circuit 102 and the result is transferred to a record digital signal processing circuit 11. Mean while, only an amplitude reference signal is sampled by a reference signal sampling circuit 103 to be given to a comparator 101. The comparator 101 controls the characteristic variable controller 100 based on a deviation from a reference obtained from a reference signal generator 30 for correction of a sampling phase by a digital operation. Due to this configuration, correction can be carried out even if circuit variance and signal attenuation exist, and a quantization distortion does not follow a dubbing.

Abstract: PURPOSE:To prevent a pipe line system from being blocked, by connecting a sea chest with a heat-exchanger for cooling an engine through two water feed pipe lines so that one of them is used as a water suction pipe line and the other one of them is used as a water discharge pipe line or vice versa in accordance with predetermined conditions. CONSTITUTION:When a suction side filter 35A in a pipe line system in a condition as indicated by the solid line arrow is clogged exceeding an allowable limit, a computer 40 issues a change-over instruction in accordance with a pressure lowering signal from a pressure detector 41A so that a four-way selector valve 39 is changed over as shown by the broken line. Accordingly, small ice pieces, foreign object, etc. causing the blocking of the filter 35A are pushed back into a sea chest 20 by a reverse stream of hot sea water, and therefore, the filter 35A is cleaned. Thus, the sea chest side part 31B1 of a water feed pipe line 31 severs as a suction pipe line. However, when the pressure in the pipe line is lowered to a lower set value since the filter is gradually cogged, the four-way selector valve 39 is returned to its original position as indicated by the solid line in accordance with a signal from a pressure detector 41B to clean the filter 35A.
