    摘要: The coordinate indicating objects are cross-shaped and aligned between the ball and cup. The virtual space has X axis from left to right, upward Y axis and Z axis toward depth direction. The coordinate indicating objects are arranged in a manner of check pattern on the X-Z coordinate. The Y-coordinate are set on the ground of course. The inclination indicating objects moves in descent direction between a pair of the coordinate indicating objects in a speed determined by the inclination value of the coordinate indicating objects adjacent in X or Z direction, that is, a difference of the Y-coordinate of the coordinate indicating objects. Therefore, clear expression is possible of inclination of inclined planes etc. without deteriorating natural atmosphere of a virtual space.

    摘要: In order to precisely measure the speed of memory unit, the memory unit stores at least one bit data at a predetermined bit position at each memory word such that the logical value of the one bit data changes alternately in order of memory address. An address increment circuit, which is provided in a module including the memory unit, successively generates memory addresses which are applied to the memory. The address increment circuit increments a memory address in response to the output of the memory. The memory speed between two consecutive memory outputs is detected by measuring a pulse width of a pulse signal outputted from the memory unit. Thus, a relatively large delay otherwise caused at a buffer amplifier can effectively be compensated.

    摘要: The invention provides a phase synchronization system which stops, when an input of a phase reference signal from the outside stops, oscillation of a voltage-controlled oscillator to achieve reduction in power consumption and can produce and output a system clock signal free from high frequency pulse noise from the voltage controlled oscillator. The system includes a phase comparator, a phase synchronization circuit including a low-pass filter and a voltage-controlled oscillation circuit, a clock detection circuit for detecting the clock signal from the outside, a phase coincidence discrimination circuit for discriminating a phase coincidence condition at the phase synchronization circuit, an AND gate, and a stop/start control circuit including a pair of flip-flop circuits. When the clock signal from the outside stops, oscillation of the voltage-controlled oscillation circuit is stopped with control information from the stop/start control circuit. When the input of the clock signal is resumed, a phase synchronization signal from the voltage-controlled oscillation circuit is outputted to the outside via the AND gate after phase coincidence is discriminated by the phase coincidence discrimination circuit.
