Abstract: According to the supercharging pressure control device of the present invention, the speed of the turbocharger of an internal combustion engine for an aircraft is controlled by adjusting the opening of a waste gate valve. In the control device of the internal combustion engine, an inlet air flow rate of a turbocharger compressor, an inlet air pressure, an inlet air temperature, and an air-fuel ratio of the internal combustion engine are detected by respective corresponding sensors. Under these conditions, a pressure ratio of the compressor where the turbocharger is operated near the maximum allowable speed is calculated. At the same time, the waste gate valve opening is controlled so as to obtain the calculated pressure ratio. By this, the turbocharger is constantly operated near the maximum allowable speed. Therefore it becomes possible to operate the internal combustion engine with the maximum supercharging pressure under the operating conditions.

Abstract: An engine including a supercharger wherein a waste gate valve is provided in the bypass passage bypassing the exhaust turbine of the supercharger and the supercharged pressure is controlled by the waste gate valve so that when the opening of the throttle valve provided in the intake duct falls under a set level, the air-fuel mixture is made lean and when it becomes greater than the set opening, the air-fuel mixture is made rich. When the air-fuel mixture is changed from a lean to rich mixture, the opening of the waste gate valve is made larger to reduce the supercharged pressure and thereby prevent abrupt fluctuations in the engine output.

Abstract: A low cost analog-to-digital converter having a non-linear conversion characteristic produces an output digital signal non-linearly relative to an input analog transmission signal which is applied thereto for demodulation. A compensation circuit having a non-linear conversion characteristic converts the non-linear digital signal output from the analog-to-digital converter into a linear digital signal which has a larger number of bits than the non-linear digital signal.

Abstract: In an airplane thrust control apparatus, a control unit (EEC) for controlling the throttle valve opening of an internal combustion engine installed in an airplane and the propeller revolution speed is provided in order to control the engine to appropriate conditions suitable to various flight conditions. During normal operation, the EEC sets the throttle valve opening and the propeller revolution speed in accordance to the stroke of a single power lever. However, if it is determined that the airplane is descending, the EEC sets the throttle valve opening to a value less than the normal set opening, and sets the propeller revolution speed to a high revolution speed equal to or higher than a predetermined revolution speed, regardless of the set revolution speed. Therefore, the thrust control apparatus is able to achieve a sufficient descending rate by reducing the engine output while maintaining high supercharger revolution speed high and maintaining required cabin pressurization.

Abstract: A facsimile machine includes a data transmission speed shift down function according to which the data transmission speed is shifted down from its initial speed to one of a plurality of new speeds based on a ratio between the total number of data frames initially transmitted to a receiver and the number of data frames requested for retransmission by the receiver. In this manner, an optimal new data transmission speed may be accurately and expeditiously determined. A parameter memory containing information regarding destination areas to which an error correction mode of operation is to be used may be preferably provided in a facsimile machine having both of an error correction mode (ECM) and a normal mode. With this structure, the ECM mode can be automatically set. In such a facsimile machine having both an ECM and a normal transmission modes, a common buffer memory is provided for temporarily storing coded image information either in the ECM or normal transmission mode.

Abstract: In a method for shifting down a data transmission rate at a transmitter in response to a request from a receiver for retransmission of data frames having data errors in a digital transmission system such as a facsimile system, when transmission errors occur, the receiver transmits a request to the transmitter for retransmission of one or more data frames for which one or more data errors have occurred. At the transmitter, the data transmission rate is shifted down from the first data transmission rate to a second data transmission rate which is used for retransmitting the data frames for which one or more data errors have occurred. The above shift-down operation is controlled by calculating an expected value indicating a possibility of the occurrence of a data error at the time of retransmitting the data frames in which one or more data errors have occurred, on the basis of a number of data frames requested to be retransmitted and a total number of data frames which have been transmitted from the transmitter to the receiver.

Abstract: A synchronization detecting system for data transmission in which a two-dimensionally modulated signal is received by way of a demodulator. In a training sequence for a two-dimensional modulation modem, a point of transition from an alternation to a pseudorandom symbol sequence is detected by producing a sum of the vectors of two signals which are remote from each other by a period of two samples, or a difference therebetween. Whether the detection of the transition point has been correct is decided utilizing the alternation.
