Title: Receiver
Inventor: MOGI MINORU
IPC: H04B1/707
Filed: 1995-02-07
Abstract: PURPOSE: To prevent occurrence of an identification error of a demodulation signal due to deteriorated S/N by detecting a level of a demodulation output of a SAW matched filter and using the result for a reference signal for discriminating the identification after detection. CONSTITUTION: A level of a burst demodulation output of a correlation demodulation section 1 is detected by a level detection section 7 and given to a positive comparator section 3, inverted by a polarity inversion section 8 and given to a negative comparator section 4 respectively as comparison reference voltages. The comparison reference voltages of the comparator sections 3, 4 are changed in response to a change in the detection level of the delay detection signal 2 due to fluctuation in the reception signal level. Thus, stable data demodulation is attained against the reception level fluctuation due to a change in the radio transmission environment. Part of an output of a synchronization pulse generating section 6 is given to a band limit section 26, in which a sine wave with the same period as that of the demodulated burst signal is extracted and given to a comparison reference signal to the negative polarity comparator section 4 to improve the dynamic characteristic and the reception S/N.

IPC: G09B5/02
Filed: 1990-01-31
Abstract: PURPOSE:To effectively make use of information on an error made by a learner before and to improve an educational effect by setting the display area of KR information on a screen and simultaneously displaying specified number of KR information. CONSTITUTION:When the learner inputs an answer and the KR information which should be outputted for the answer exists, a CPU 1 judges whether or not there is a blank line in a frame where the KR information on the screen is displayed. In the case that the blank lines exist, the KR information is dis played in the uppermost line out of the blank lines. Meanwhile, when the blank line does not exist, the display of the oldest KR information that is displayed in the first line of the display frame is erased and other KR information is displayed again in the line which is one line upper. Thus, the KR information is displayed in the lowermost line which gets black. The above display processing is repeatedly performed every time the answer to the question is inputted from the learner, and plural pieces of new KR information including the latest KR information are simultaneously displayed on the display frame.

Time interval Δt of a vibration suppression to divide a pair of thrusters into two ignitions is determined by the following expression: Δt=(1/2)×(1/F)×SF. In this case, At is time interval (second) to ignite a pair of thrusters, F is a frequency of a main mode (a nominal first mode) of a Hertz unit for each shaft, and SF is a scale factor for adjusting for the nominal frequency. Thus, the vibration of the solar battery array panel which is caused by the ignition of the first low thrust thruster is canceled by a second ignition delayed by a half period.
