摘要： PURPOSE:To minimize the part to be repainted by detecting the difference in the vibrational or sonic characteristic of a spray nozzle to judge the clogging. CONSTITUTION:The difference between the vibrational or sonic characteristic of the spray nozzle when paint is sprayed in the normal operation and the characteristic when the nozzle is clogged is detected to judge the clogging state of the spray nozzle. Namely, since the clogging state can be judged immediately after the spray nozzle is clogged, the part to be repainted can be minimized. Moreover, clogging can be avoided immediately before the nozzle is clogged by obtaining an accurate detection value, and spraying can be continuously carried out. Meanwhile, since the structure of the diagnostic device is simple and the detector is compact, the workability can be remarkably improved by simultaneously using many spray guns provided with the detector.

摘要： PURPOSE:To safely and effectively control adhesive marine life over a long period at a low cost, by mixing an insoluble oil with a resin, etc., to obtain a jelly or rubbery antifouling material and attaching the material to the surface of a structure contacting with seawater. CONSTITUTION:The adhesion of adhesive marine life to a marine construction such as lighted buoy or seadrome, etc., or a cooling pipe, etc., can be prevented by attaching an antifouling material to the surface of the construction, etc., contacting with seawater. The antifouling material is a plastic material having excellent tensile strength and produced by mixing clay or resin to an insoluble oil (e.g. machine oil, food oil, waste oil, etc.) used as a main component and solidifying the mixture in jelly or rubbery state. For example, a machine oil is added with a plasticizer and the mixture is combined with a general-purpose resin to obtain an Oil-jelly (commercial name) which liquefies at 140-180 deg.C. The jelly is cast on to a substrate having surface-protrusions, etc., and cooled to obtain an elastic solid, which is attached to the surface of a construction e.g. with an adhesive.

摘要： PROBLEM TO BE SOLVED: To simultaneously satisfy both of the cost performance and the safety by mounting a fixed support and a movable support on a floor of a conveying path, and providing the supports with the different frictional coefficients so that one of the supports has a function for reducing the friction with respect to a heavy article, and the other support is provided with a braking function with respect to the heavy article. SOLUTION: A fixed support 30 and a movable support 40 respectively having the frictional coefficients largely different from one another, are mounted along the moving direction on a conveying surface of a conveying path 20. The fixed support 30 is made of concrete having high frictional coefficient with respect to a steel material 11, and partially abutting on the bottom steel material 11 of a heavy article 10 to support a body weight of the heavy article 10 at all times, and further exercises the braking function in the movement. The movable support 40 comprises an elevation part 41 providing the friction reducing action in the movement, and an elevating means 42 for moving the elevation part 41 up and down, and the elevation part 41 is raised in the movement of the heavy article 10 partially abutting on the bottom steel material 11 for supporting a part of the body weight of the heavy article 10, whereby the heavy article can be economically moved in safety.

摘要： PROBLEM TO BE SOLVED: To easily prevent the clogging of a polishing material supply line by interposing a switching valve for manually communicating or cutting a pipeline with/from the atmospheric air on the way of the polishing material supply line. SOLUTION: In the case of stopping spraying by a blasting device 10, before stopping the supply of the high-pressure water, firstly, an outer pipe 22 of a clogging preventing device 20 is rotated so that each hole 24, 25 of both pipes 21, 22 coincide with each other. Polishing material inside of a polishing material supply pipe 17 near a housing 13 is discharged all for vacant. Thereafter, when the high-pressure water is stopped, since inside of the polishing material supply pipe 17 already becomes the atmospheric air pressure, reverse flow of the water in the supply pipe 17 can be prevented. In the case where the clogging preventing device 20 is provided near the housing 13, 1 second is enough for the timing between opening of the pipeline and stop of the high-pressure water. Air is made to flow into the polishing material supply pipe 17 from the clogging preventing device 20 by injecting the high-pressure water in the condition that the pipeline is opened, and the polishing material adhered near a connection part to the housing 13 is blown so as to easily eliminate the clogging.

摘要： PROBLEM TO BE SOLVED: To enable tree planting in a building congested area at low cost by providing an open ceiling part which allows a trunk part of a tree planted on the ground to pass through up to a rooftop inside a building to obtain the same effect as the case where a big tree is planted on the rooftop. SOLUTION: Trunk parts 31A to 35A of trees 31 to 35 planted on the ground grow by passing through open ceiling parts 21 to 25 of a building so that branch parts 31B to 35B of these trees become higher than a level of a rooftop R. An area of a plan of the open ceiling parts is formed to be slightly larger than trunk diameters of the trees, and trimming of branches is done when a branch grows from the trunk part so that the trunk part only passes through the open ceiling parts. Moreover, banking is done on the rooftop R to plant plants having shallow roots in order to form a rooftop park due to tree planting effect on the rooftop simultaneously. A green tract of land where big trees and plants grow is provided in a place where buildings are clustered close together without an allowance of a site without requiring great costs. Consequently, tree planting in a city part can be promoted by a simple configuration.

摘要： PROBLEM TO BE SOLVED: To make any movement in the optical direction achievable without adding a sharp improvement to a conveying truck by making it consist of a self-propelled lift truck equipped with a fork system and a self-propelled cargo-carrying truck forming an opening part, for receiving this lift truck, in a body central part, and making both of them suspendible with each other. SOLUTION: A lift truck 20 consists of both symmetrical mast frames 21 and a body frame by means of base frame, and it is equipped with two L-shaped forks 23 free of lifting motion along the mast frame 21. In addition, this lift truck 20 is equipped with a self-propelling drive motor in the A-A direction. A self-propelling cargo-carrying truck 10 is of four-wheel type, which is travelable in the B-B direction by the drive motor. Conveyance in the specified story for materials and so on is suspendibly carried out by a suspension mechanism 30 of the self-propelling cargo-carrying truck 10 after the lift truck 20 loaded in the opening part of this truck 10 enters thereinto. In addition, a movement into different stories is carried out in a state that the self-propelling cargo- carrying truck 10 is uplifted by the forks 23 of the lift truck 20. With this constitution, the self-propelling cargo-carrying truck 10 becomes travelable.

摘要： PROBLEM TO BE SOLVED: To suppress the structure of a moved floor low and facilitate maintenance and management by arranging underground pipes between an athletic facility and the outdoors, blowing out compressed air from many blowout ports formed on the underground pipes to float a floating body planted with natural turf, and moving it in this state. SOLUTION: Sediment is mounted on a frame body, natural turf 13 is planted on the sediment to form a floating turf body 1. The periphery of the lower section of the frame body of the floating turf body 1 is surrounded with a skirt made of a flexible material to hold air. Underground pipes 2 are installed between an indoor athletic facility A and the outdoors, for example, and a compressed air feeding device such as a high-pressure blower feeding compressed air is connected to the underground pipes 2. Many blowout ports 22 of compressed air are formed on the underground pipes 2 toward the ground surface in a line in the moving direction. When the floating turf body 1 is to be moved in the prescribed direction, the floating turf body 1 is floated by the pressure of the air held in the skirt and towed and moved by a winch or the like.
