摘要： 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.

摘要： 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.

摘要： 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.

摘要： A control system for an aircraft that controls the set speed of the propeller governor and the degree of opening of the throttle valve using a single control lever. The speed setting mechanism of the propeller governor is directly connected to the power lever by a push and pull cable, and the set speed of the propeller governor changes in proportion to the stroke of the power lever. Therefore, the propeller speed changes in proportion to the stroke of the power lever. On the other hand, the throttle valve is connected to the power lever by a nonlinear cam and a push and pull cable. Therefore, the degree of opening of the throttle valve does not change in proportion to the stroke of the power lever (i.e., the change in the degree of opening of the throttle valve has a nonlinear characteristic), and the engine output power changes in the nonlinear manner with respect to the change in the propeller speed. By setting the nonlinear characteristic in the change in the engine output power with respect to the change in the propeller speed, an optimum relationship, between the engine speed and engine output power, for the aerodynamic characteristics of the aircraft can be obtained.

摘要： An equalization system wherein a signal received over a line is equalized and the quantity of equalization is compensated based on a difference, or error, between the equalized received signal and a signal which is estimated from the received signal, including a tuning device which compensates the amount of equalization by training, which precedes reception of communication data. A difference or error range which is usable for the compensation of the quantity of equalization is set up during a training sequence. The error range sequentially increases as the training sequence proceeds. Thus, decision feedback updating during the training sequence only occurs so long as the difference between the equalized received signal and a signal which is estimated from the received signal is within the error range, which is sequentially increased during a training sequence. After completion of the training sequence decision feedback updating is always allowed.

摘要： 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.
