Abstract: PURPOSE:To surely hold a part, etc., without damaging it, by installing a plurality of tubes onto a core body and expanding each tube by pouring fluid into each tube and catching the part by utilizing the hole on the part, in a catching device for cylindrical parts, etc. CONSTITUTION:Each edge of a tube 2 having the opened ports at the both edges is installed in sealed state onto the upper and lower parts of a hard core body 1. A flow passage 3 for pouring fluid such as air into the tube 2 is formed on the core body 1, and in each flow passage 3, a piping hose 4 is connected, and a valve 5 is installed midway in the hose 4, and a fluid feeding source 6 is connected. The fluid such as air which is supplied from the fluid feeding source 6 is distributed into each piping hose 4 from the position of the valve 5, and flows into the passage 3, and expands the tube 2. The drawing shows the state where a part W is caught. The tube 2 is opened at the both edges, and installed in sealed state onto the outer peripheral surface of the core body 1 by the caulking rings 7 and 8.

Abstract: PURPOSE:To make it possible to run and move inside a tube without fail by a method wherein one end of a cylindrical tube is fitted on one end side of a core shaft while the other end thereof is folded back outside in the radial direction and fitted on the other end side of the shaft, and a fluid is injected in and discharged from the tube to make the tube expand and contract. CONSTITUTION:A moving body 1 is formed by fitting one end of a tube 3 of an elastic body (rubber) on the fore end 5 side of a core shaft 2 (by using a calking ring 9) and by folding back the other end of the tube 3 outside in the radial direction and fitting the same on the base end 6 side of the shaft 2. When a pressure fluid (gaseous body) is injected into the moving body 1 through a pressure fluid conducting pipe 4, the tube 3 is made to expand asymmetrically on the fore end 5 side and the base end 6 side and comes into contact with the inner surface of a pipe 11. When the pressure fluid is injected further to increase a contact area, the core shaft 2 is moved by a distance DELTAl toward the fore end 5 side while the tube 3 is fixed on and supported by the inner surface of the pipe 11. When the pressure fluid is discharged, the moving body 1 stops as a whole at the position whereat the fluid is discharged. By the repetition of these operations, the moving body 1 runs forward toward the fore end 5 side in the axial direction inside the pipe 11.

Abstract: PURPOSE:To measure a car height with high accuracy regardless of the contamination of an optical system or temp. change, by connecting a voltage compensation circuit always keeping the light receiving intensity due to the photoreceptor of a compensating optical system constant to the light emitting elements of measuring and compensating optical systems. CONSTITUTION:The light emitting element LED 1 and photoreceptor Ph1 of a measuring optical system 5 and the light emitting element LED 2 and photoreceptor Ph2 of a compensating optical element 6 are mounted on the top wall 3a of an outer shell 3 and the reflecting plate R1 of the optical system 5 is mounted on the cylinder 2b of a shock absorber 2 and the reflecting plate R2 of the optical system 6 is mounted on a cylindrical body part 3b. The output voltage e2 from the element Ph2 is fed back to a voltage compensating circuit 7 and the supply voltage ec from the circuit 7 to the LED 2 is controlled so as to always keep the voltage e2 constant in the circuit 7 regardless of the contamination of the optical system 6 or temp. change and a supplied to the LED 1. Therefore, the optical system 5 receives the same contamination or temp. change of the optical system 6 but the effect thereof is erased almost perfectly by the control of the voltage ec and the output voltage from the element Ph1 always has sufficient accuracy.

Abstract: PROBLEM TO BE SOLVED: To provide a plurality of clamping devices in parallel, and clamp parts at one time even if the parts to be clamped are in a row, and to make the matters worse, even if each interval is narrow, and make a clamped part rotatable if it is required. SOLUTION: A fluid injection port 2 is formed in the upper surface of a hard main body part 1, concurrently a fluid injection passage 4 is formed in the main body part 1, an outer cylinder 7 is mounted thereto in such a way that the hard main body part 1 is covered therewith, one end of a tube 5 which is opened at both ends of it, and is composed only of a rubber tube in continuous length that is cut into a specified length, is put over the lower part of the hard main body 2 so as to be mounted onto the outer circumference of the hard main body 1 by a squeezing ring 9, the other end of the tube is folded back to the outer side so as to be mounted onto the lower end outer circumference of the outer cylinder 7 using a squeezing ring 6, and it is so constituted that fluid such as air and the like is injected from the fluid injection port 2 through the fluid injection passage 4 into a space between the tube 5 and the outer cylinder 7 in such a way that the tube 5 can be swelled up inward, a part and the like to be clamped have been inserted in the inside of the tube 5 before fluid is injected, and the part and the like are so designed as to be clamped only by the swelled-up surface of the tube 5.

Abstract: PURPOSE:To make compact the whole structure of a gripping device and eliminate risk of breaking an elastic inflating body by fitting in the base, frames for fixing the two ends of the inflating body to the bore of the base, and deforming the base in diameter contraction to the frames or deforming the frames in expansion to the base. CONSTITUTION:A gripping device for parts, etc., has a hollow base 1 in cylindrical form and an elastic inflating body 2 which is installed at the bore of the base 1 and whose two ends are fixed to the base 1, and the inflating body 2 is constructed expansive by injecting a fluid from a supply/exhaust port 4 into an enclosed space 3 bounded by the bore of the base 1 and the inflating body 2. Frames 5, 6 for fixation of the two ends of the body 2 to the bore of the base 1 are fitted in the base 1, and the base 1 is deformed in diameter contraction to the frames 5, 6 so that caulked parts 7, 8 are formed at the two ends of the base 1. Therefore, the outside diameter of the whole device is lessened in an amount corresponding to the part free from mounting with the ends of the body 2 folded back outward. Even though the angle of a work 200 is going to run against the body 2, it contacts the frame 6 which prevents breakage of the inflating body.

Abstract: PURPOSE:To softly grasp a plant or the like by constituting a device sealing both ends of an inflation unit mounted to a hard base body while forming a passage for supplying fluid to and discharging it from the inflation unit and injecting the fluid between the hard base body and the inflation unit through the passage so as to grasp the plant or the like between the two or more inflation units inflated. CONSTITUTION:For drawing out from a vessel a plant 20 growing in the vessel, two grasping devices inflate each inflation unit 1 grasping the plant 20 from its both side in such a manner that the plant 20 is caught between the respective inflation units 1. That is, the plant 2C is grasped by the four inflation units 1. And, in the case of a device mounting the two inflation units 1 in the direction of the axial line of a hard base body 2, a pipe shaped part or the like can be grasped between these inflation units 1.
