摘要： PURPOSE:To stabilize the attitude in execution of cleaning work for a cave such as a tunnel with a movable frame provided therein by a method wherein the movable frame is turned around by tractive force of an operating rope and thereby main guide rollers are brought into contact intensively with walls of the cave. CONSTITUTION:An operating rope 1 is stretched in a cave such as an inlet channel of a power plant and a movable frame 2 of a movable truck Y is provided in the middle of the rope. Then, the operating rope 1 is pulled, and tension is given thereby to the rope 1 and auxiliary ropes 10. The ropes 10 are allowed to move by means of equalizer sheaves 11 and at the same time, the positions of the sheaves are made offset from the centerline between the right and the left sides as parts where the ropes 10 are connected to the frame 2 are offset each other. Then, difference is made between moments on the right and the left by tension of the ropes 10, making turning force act on the frame 2. One side of the frame 2 is drawn to the direction in which the rope 1 is pulled, making main guide rollers 3A and 3B to be pressed against the inner wall surfaces. The rope 1 is wound further to move the frame, and substances stuck to the wall surfaces are removed with scrapers 6. Thereby works can be executed accurately in stabilized attitude.

摘要： PURPOSE:To reduce the generation of trouble by simplifying a mechanism for pressing a scraper in the cleaning device of an intake passage and to extend the life of the scraper. CONSTITUTION:A cleaning device is equipped with a moving frame member 2 drawn by an operating rope, a guide roller, a shaking arm 5 having a submerged blade 4 generating lift pressing a scraper 5 to a wall surface B by a water stream, and the scraper 6 scraping the ocean organisms attached to the shaking arm 5. The submerged blade 4 generates lift by a water stream to press the scraper 6 to the inner wall surface of an intake passage A.

摘要： PROBLEM TO BE SOLVED: To provide a radio communication equipment, whereby the number of radio channels is increased and also interference is prevented from occurring between the respective base stations of plural radio zones by using only a frequency band which is assigned in a conventional manner, without use of a new frequency band. SOLUTION: The channels used as reception channels R1 and R2,... conventionally out of the previously provided channels T1, T2, T3,..., R1 and R2,... are used as transmission channels Tn-1, Tn,.... An interleave channel is newly provided in channel separation between the adjacent channels of respective transmission channels T1, T2, T3,..., Tn-1 and Tn,... and the channels are assigned to reception channels R1, R2,..., Rn-2 and Rn-1,.... Thus, the number of transmission channels are increased, and also the number of reception channels are secured, so that the number of the radio channels being useable within the range of the frequency assigned in the conventional manner is increased.
