摘要： PROBLEM TO BE SOLVED: To reduce an uncleaned area generated at the corner of a room by using a self-traveling type vacuum cleaner.
SOLUTION: The self-traveling type vacuum cleaner 1 having a cylindrical side face cover 23 is provided with a suction port body 30 which can be displaced in side directions to an advancing direction. The side face cover is held at a base 45 through a suspension 7. At the time of cleaning the corner part of the room, the vacuum cleaner travels with the suction port body along a wall and the displacement amount of the suction port body is changed as the vacuum cleaner approaches the corner part. When an obstacle hits the vacuum cleaner, the side face cover is displaced and hits side face cover switches 24a-24d and the direction of the obstacle is detected.

摘要： PURPOSE:To securely detect possibility for damage from a conduit system side by connecting a resonating circuit in which detecting current is resonated to vary in high impedance between an underground metal conduit and a corrosion preventing device. CONSTITUTION:Earth points i, i+1,... are provided at prescribed intervals on a conduit 1. On the other hand a detector 2, a power source 3 and resonating circuits 4 are connected to a conduit system 1 at a point i, and the earth side is linked to a corrosion preventing device 7. In the case where an excavator 5 damage the conduit at a damage part 6, the voltage and the current of a signal varies because the impedance is considerably low at this point. This variation is grasped by the detector 2. Further, in regard to the deciding of the damage part 6 time difference of damage signals from each point at which the detector 2 receives is computed at a relay point or at the center. Since the resonating circuits 4 are inserted at each earth part i, i+1, ..., and high impedance is formed for the signals of the power source 3, the current signal is very little from the conduit system 1 to the earth and so the signals go on long distance.
