IPC: G06F12/16
Filed: 1984-10-24
Abstract: PURPOSE:To generate an automatic clear signal by using a charge share circuit comprising a precharge MOSFET operated by two timing signals having a different phase and applied externally without being overlapped together and an MOSFET transferring the charge of a capacitor charged up by the precharge MOSFET to another capacitor. CONSTITUTION:Timing signals phi1, phi2 are formed into timing signals whose high level (common point of circuit) it not overlapped and without different phase. When the timing signal phi1 is at a high level. When the timing signal phi1 is at high level, an N channel MOSFETQ1 is turned on to precharge the capacitor C1 to a power supply voltage V level. Then when the timing signal phi2 is at a high level, an N-channel MOSFETQ2 is turned on, and the electric charge of the said capacitor C1 is transferred to the capacitor C2 according to the capacitance ratio and both the electric amounts. Through the repetitive operation above, the voltage N1 of the capacitor C2 is increased stepwise.

Title: Data transfer system
Inventor: AOYAMA NORIYUKI
IPC: G06F13/28
Filed: 1989-08-29
Abstract: PURPOSE:To shorten the time required for transfer of continuous addresses by setting a start address to an address generating circuit with an I/O command and writing or reading only the transfer data into or out of a memory. CONSTITUTION:A store address is set to an address generating circuit 2 with an I/O command and then the transfer block number is set to a transfer block number circuit 6 with an I/O command. Hereafter the address is neglected and only the transfer data is written into a memory 1. At the side of the mem ory 1, a control circuit 5 adds 1 to the address of the circuit 2 every time the data is inputted to a FIFO (first-in first-out) 4-1 and sends a write pulse to the memory 1. As a result, the data is once stored in the FIFO 4-1 and the time required for transfer of data is shortened since the writing speed of the FIFO 4-1 is higher than that of the memory 1.

Next, when the channel B is received, control so as to apply tuning to a point fnT being shifted by  f is performed by the microcomputer 8 setting the frequency fn-1T receiving at present as reference. In other words, when tuning to the channel B is performed, a tuning point fnT=fn-1T+ f is calculated. And the microcomputer 8 outputs the frequency fnT to a phase comparator 9, then, performs the channel selection.
