Title: Drawing processor
Inventor: NAKAMURA KOZO
IPC: G06F3/048
Filed: 1990-01-22
Abstract: PURPOSE:To reduce the task switching frequency per unit time by increasing the starting cycle of the task which carries out the drawing or pointing processing. CONSTITUTION:At least the drawing coordinates or the pointing coordinates are extracted at a sampling rate R(/sec), and the coordinates extracted within the cycle t time are collectively processed and displayed for each cycle T (T XR>=2). As the cycle T is larger than the coordinate input cycle 1/R set by the rate R, the starting interval of a coordinate or pointing processing task is increased in comparison with a conventional system where the coordinate and pointing tasks are carried out for each input of coordinates. In such a way, the starting cycle is increased for the task which performs the drawing or pointing processing. Thus the task switching frequency is reduced per unit time.

Filed: 1983-01-31
Abstract: PURPOSE:To control the uneven amplitude of a position signal and to stabilize a servo loop by providing a circuit detecting maximum servo signal value between a servo signal amplifier and an AGC voltage generator. CONSTITUTION:A servo signal 20 amplified by a servo signal amplifier 1 is sent to a diode 6 of a detecting circuit 5 for servo signal maximum value.

The current supplied to the diode 8 flows into a capacitor 9 and does not flow backward, and therefore the potential at the terminal of the capacitor 9 is kept at the maximum value of the servo signal. A resistance 10 is used for discharge of the capacitor 9 and decides the holding time of the maximum value of the servo signal with the time constant of a CR. An operational amplifier 11 is used as a voltage follower, and the maximum voltage value of the servo signal is detected at the output of the amplifier 11.
