Nikko Circuit

With the many hot springs, museums, and culinary experiences the city has, Nikko offers an endless number of activities to choose from; not to mention the iconic racetrack - and accompanying sports cars - that sit just outside the city limits. Hosting some of Japan's best drifting meets since the early 2000s, Nikko circuit remains a favorite amongst locals for its intimate experience and challenging drifting lines.

Nikko Circuit

The above described missile launcher raising and lowering mechanism and the missile launching mechanism are operated under the control of a control unit as follows. A configuration of the control unit is illustrated in FIG. 7. The control unit comprises the following elements. An antenna 53 is provided for receiving control signals having been transmitted from a transmitter. A receiver 37 is provided to be electrically connected to the antenna 53 for fetching the control signals from the antenna 53 and then demodulating the fetched control signals. A control IC 39 is provided to be electrically connected to the receiver 37 for fetching the demodulated control signals and then generating a steering signal, forward/reverse signals, a missile launching signal and missile launching stage raising and lowering signals. A steering driving circuit 40 is provided to be electrically connected to the control IC for fetching the steering signal from the control IC and also connected to a steering unit 41 for controlling the steering unit in accordance with the fetched steering signal. A driving motor driver circuit 42 is provided to be electrically connected to the control IC 39 for fetching the forward/reverse signals from the control IC 39 and also connected to a driving motor 43 for controlling the driving motor 43 in accordance with the fetched forward/reverse signals. A missile launcher driving circuit 44 is provided to be electrically connected to the control IC 39 for fetching the missile launcher raising and lowering signals from the control IC 39 and also connected to a missile launcher raising and lowering motor 47 for controlling the same. A missile launching control circuit 46 is provided to be electrically connected to the control IC 39 for fetching a missile launching signal from the control IC 39. The missile launching control circuit 46 comprises flip-flop circuits. A missile launching driving circuit 48 is electrically connected to the missile launching control circuit 46 for fetching the missile launching control signals from the missile launching control circuit 46 and also connected to the motor 47 for control operations of the motor 47 in accordance with the fetched missile control signals so that the motor 47 is driven only when there appears a requirement for launching the missile. A control switch is provided to be connected to the missile launcher driving circuit 44, the motor 47 and the missile launching control circuit 46. The above circuits, units and motors are operable by receiving power from a battery 38.

When the missile launcher raising and lowering switch 36 of the radio transmitter 34 is turned ON, the radio transmitter 34 transmits the missile launcher raising and lowering signals to the control unit. The missile launcher raising and lowering signals is transmitted via the receiver 37 to the control IC 39. The control IC 39 feeds the missile launcher raising and lowering signals to the missile launcher driving circuit 44. The missile launcher driving circuit 44 drives the motor 47 placed on the missile launcher 1 so that the fourth gear 10 rotates in the clockwise direction represented by the arrow mark of real line FIG. 6. As described above, the rotation of the fourth gear 10 in the clockwise direction is transmitted to the seventh gear 13. Since the arm 2 comprising the first and second portions 2a and 2b is fixed to the seventh gear 13, the rotation is then transmitted to the arm 2 whereby the raising and lowering motions of the missile launcher 1 are caused.

When the missile launcher raising and lowering switch 36 of the radio transmitter 34 is turned OFF, the transmission of the missile launcher raising and lowering signals is discontinued whereby driving of the motor 47 by the missile launcher driving circuit 44 is also discontinued. As a result, the raising and lowering motions of the missile launcher 1 are then discontinued. The missile launcher 1 can be set at a desirable position by keeping the missile launcher raising and lowering switch 36 in the ON state until the missile launcher 1 reaches the desirable position. If the missile launcher raising and lowering switch 36 is kept in ON state, then the raising and lowering motions of the missile launcher 1 are also continued.

On the other hand, the missile launching control will be described. In order to launcher the missile, it is necessary that the missile projector 32 is placed above the toy car. A first switch 45a is provided in the vicinity of the arm 4 to detect position of the missile launcher 1. For example, as illustrated in FIGS. 3 and 4, the arm 4 is provided with a projecting portion 50 so that if the missile launcher 1 is accommodated in the toy car, then the projecting portion 50 pushes the switch 45a. When the projecting portion 50 of the arm 4 pushes the switch 45a, then the missile launcher control circuit 46 does not feed the missile launching signal to the missile launcher driving circuit 48. If, however, the missile launcher 1 is raised and positioned above the toy car, then the projecting portion 50 of the arm 4 is detached from the switch 45a whereby the missile launcher control circuit 46 feeds the missile launching signal to the missile launching driving circuit 48. As a result, the missile is launched from the projector.

In conclusion, when the projecting portion 50 of the arm 4 pushes the switch 45a, the control IC 39 feeds a missile launching inhibiting signal to missile launching control circuit 46 whereby the missile launching control circuit 46 does not feed the missile launching signal to the missile launcher driving circuit 48.

The missile launching operations will be described as follows. When the missile launching switch 35 provided on the radio transmitter 34 is pushed, then the missile launching signal is transmitted to the control unit and received by the antenna 53. The missile launching signal is then transmitted via the receiver 37 to the control IC 39. The control IC then feeds the missile launching signal to the missile launching control circuit 46. The missile launching control circuit 46 confirms that no missile launching inhibiting signal is generated via the first switch 45a which is detectable to the position of the missile launcher 1, before the missile launching control circuit 46 feeds the missile launching signal to the missile launcher driving circuit 48. If the missile launching inhibiting signal is generated via the first switch 45a, then the missile launching control circuit 46 does not feed the missile launching signal to the missile launcher driving circuit 48. Thereafter, if the missile launcher 1 is raised then the missile launcher driving circuit 48 receives the missile launching signal from the missile launching control circuit 46. The missile launching control circuit 48 drives the motor 47 so that the fourth gear 10 rotates in the counter-clockwise direction represented by the arrow mark of broken line as in FIG. 6. As a result, the missile releaser 25 rotates so that the missiles are released from the missile holder 27 and launched by the spring force of the spring member. 041b061a72
