IPC: H04N7/18
Filed: 1990-03-15
Abstract: PURPOSE:To enable stable travel by executing optimum regulator control so as to converge a position and angular deviation from a target route to zero. CONSTITUTION:Position deviation Xerr on an X axis to a target route OC at the current position of a car 11 and angle deviation THETAerr between the direction of the route OC and the traveling direction of the vehicle 11 is detected and steering is executed so as to converge both or one of the deviation to zero. Namely, while utilizing the optimum regulator, with the deviation Xerr or THETAerr as a state amount and a steering angle as a control amount, the steering angle is controlled so as to converge the deviation to zero. An angle THETA in the traveling direction is calculated by integrating a detected yaw rate T of the vehicle 11 with an integrating element 12 and an angle THETAref in the route OC direction is obtained from data on the X-Y coordinate of the route OC so that the angle deviation THETAerr can be calculated. Then, current vehicle position Xn and Yn are calculated from vehicle velocity (v) and the angle THETA and points Xref and Yn on the route OC are calculated corresponding to the Yn value. Afterwards, the deviation Xerr between the Xn value and the Xref value is calculated. Thus, the stable travel is enabled.

Title: Delay switch
Inventor: TAKADA TAKASHI
IPC: H01H43/30
Filed: 1990-03-15
Abstract: PURPOSE:To lower the cost and also to make load ON-operation light so as to eliminate any feeling of disorder by using a shape-memory resin for delay operation. CONSTITUTION:Under the condition that a switch handle 4 is in OFF operation, a shape-memory resin 1 is heated by a heater 5. When the handle 4 is turned ON, a movable contactor 8 starts ON operation at the pushing part 9 and consequently, electric power is supplied to load 7 and at the same time an external pressure is applied to the heated resin 1 so that this resin may be deformed. Further a heater switch part 6 becomes OFF state so that the heater 5 is ceased and the resin keeps its deformed shape. Then, when the handle 4 is turned OFF, the pushing part 9 is separated from the contactor 8 but the resin 1 keeps the deformed state and the contactor 8 is kept in ON operation state and electric power is continuously supplied to the load 7. Moreover, since the switch part 6 becomes ON, the resin recovers its original shape after a time passes and the contactor 8 is turned OFF. As a result, the electric power to the load 7 is stopped after a prescribed time.
