Title: Bias setting device for buffer memory
Inventor: OSAKI KIMIYA
IPC: H04L13/08
Filed: 1988-09-20
Abstract: PURPOSE:To set the phase difference between the write timing and the read timing so that it has always a maximum margin by setting the bias between the write timing and the read timing again at the time of starting the operation of a system. CONSTITUTION:A write control means 13 and a read control means 14 start the operation at the time of rise of the whole of the system, and output of a write control signal 15 and a read control signal 16 is started at independent timings. At this time, phase relations between respective output timings of the write control signal 15 and the read control signal 16 are not secured. The bias setting operation is performed at the time of system rise by a bias resetting means 17. Thus, the means 17 gives a maximum margin to the bias between output timings of the read control signal 16 and the write control signal 15, and the operation of a buffer memory means 10 is started in this state.

Filed: 1989-09-08
Abstract: PURPOSE:To facilitate picture drawing processing by providing a holding means to store the pattern coordinate of the point at the time of the finish of one picture drawing command when the picture of a continuous thick line is drawn. CONSTITUTION:A pattern coordinate output circuit 20 is constituted of a muROM 21, a mu sequencer 22, a logical pel control circuit 23, a pattern starting position register 24, a pattern coordinate output register 25, and a working register 26 and so on. Then, when the sequencer 22 detects the finish of first thick line picture drawing, it outputs a transfer directing instruction to the register 26 and the pattern coordinate at the time of the finish of a first thick line picture drawing command is stored in the register 25. A user accesses the contents of the register 25 from an external part, and writes them in the register 24, and starts the next picture drawing. Thus, by providing a means to hold the last thick line coordinate, complicated work such as calculation for setting a pattern starting position can be made unnecessary.

IPC: G01K7/24
Filed: 1987-09-18
Abstract: PURPOSE:To prevent an once-through current from flowing to an inverter, by providing a potential control means for fixing the potential of the input terminal of the inverter to an earth point or power supply voltage when all of switching means are brought to an OFF-state. CONSTITUTION:When both of try state buffers TSB1, TSB2 are brought to an output high impedance state by control signals CNT1, CNT2, the feedback circuit of an inverter INV is blocked and oscillation can be stopped. Moreover, when both of the control signals CNT1, CNT2 are brought to a low level and the outputs of two try state buffers TSB1, TSB2 are brought to a high impedance state, the output of an NOR gate G1 is changed to a high level. By this mechanism, the output of a try state buffer TSB3 becomes a low level and the input potential of the inverter INV is fixed to 0V. Therefore, the input terminal of the inverter INV becomes a floating state to prevent the flow of an once-through current.
