Title: Output buffer circuit
Inventor: MARUYAMA TADASHI
IPC: H03K19/017
Filed: 1982-01-20
Abstract: PURPOSE:To reduce chip occupation area by shifting the level of an input to the output buffer circuit of a low operating voltage logical system in an MOSLSI having logical systems with different operating voltages. CONSTITUTION:When the input to a signal input terminal 1 has the potential of a power source VDD, a transistor (TR) T5 turns on and TRs T1 and T3 turn off to obtain an output VDD at the drain of a TRT4. When the input has the potential of the power source VSS1, the TRs T1 and T3 turn on and the TRT5 turns off to hold the drain of the TRT3 at the potential VSS1; and an output VSS2 is obtained from the drain of a TRT10 and the output of a level shifting circuit 3 is shifted in level to the potential of the power source VSS2. Therefore, the gate voltage when a P channel side TRTP turns on is doubled to allow a current which is more than double to flow between the source and drain of the TRTP.

IPC: G03G21/14
Filed: 1979-01-26
Abstract: PURPOSE:To provide a simple construction, highly efficient sequential copying in electrophotography, copy sequence timing pulse is generated before the preceding timing pulse ends. CONSTITUTION:The clock pulse generator disk 43 contactly rotates with the light sensitive drum 9 to provide clock signal from the photo-counter 44.
