Title: Radio channel switching method
Inventor: IMAOKA JIRO
IPC: H04W72/04
Filed: 1987-03-04
Abstract: PURPOSE:To prevent the content of communication from tapping continuously by a 3rd party by switching the frequency of a radio channel used between a mobile body and a radio base station at each prescribed time. CONSTITUTION:An automobile telephone exchange station 4 operates a timer circuit 8 based on a talking start signal to start the count of a time T. When the time T is counted by the timer circuit 8, after the automobile telephone exchange station 4 selects one of idle communication channels of a small radio zone, the station executes a wire continuity test with a radio base station 2 as to a communication channel. When the result is excellent, a communication channel switching signal is sent to select a new communication channel f3 through a communication channel f2 in use at present. A mobile equipment executes the radio continuity test with the radio base station in response thereto after a new communication channel is selected. Thus, the privacy of communication is enhanced without using a special privacy equipment.

Title: Memory circuit
Inventor: IIMA TSUTOMU
IPC: G11C11/403
Filed: 1978-04-26
Abstract: PURPOSE:To realize the dynamic RAM which is stable in operation and enables self reproduction, by three MOSFET's and one capacitor. CONSTITUTION:The information is stored at the terminal of the capacitor CB, by making H the address signal phiAD and the write-in signal phiW. When the memory is at H, with the refresh signal phiRF at H, the charge provided at the node 2 via FETM3 flows to the terminal 3 by making the signal phiW at H immediately after making the signal phiRF at L, and the information is stored. When the signal phiW is taken as binary value of 0 and +V, with the memory at L, the potential at the terminal 3 is at H while the signal phiW is applied. This is because of electrons emitted when the inversion layer is eliminated while FETM2 repeats inversion. Then, the inversion layer is normally formed by taking the signal phiW at more than the threshold value of FETM2 to prevent the emission of electrons at elimination.

In the feedback control by the inverting amplifier circuit 3, the input of the D/A converter 1 is biased by a bias circuit 4. Even when a drift takes place to either positive or negative direction, the control of the black reference level to the zero V is attained.
