摘要： PURPOSE: To obtain a car gondola for working in a smokestack in which the maintenance of injection nozzles or the like is facilitated and which is excellent in labor effectiveness by supporting a device base provided with operating equipments, so as to be freely elevated or lowered, on a rotatable support cylinder suspended by a swing wire and providing upper and lower base structures on the upper and lower ends of the support cylinder. CONSTITUTION: On the lining construction of the inner wall surface 013 of a smokestack, a car gondola 19 is suspended in the stack by a one-point swing device 1. Upper and lower protruding jacks 6 and 18 are operated to abut against the inner wall surface 013 so that the position of the gondola 19 is fixed. Under this state, a lining material and high-pressure water is supplied to injection nozzles 08 for injecting to the inner wall surface 013. At the same time, a support cylinder 10 is rotated by a rotary device 9 and a device base 11 is elevated or lowered by an elevating device 12 to spray the lining material. Then, the respective jacks 6 and 18 are reversely operated so that the fixed gondola 19 is released. Thus, the gondola 19 is elevated or lowered to a prescribed height and the operations are similarly repeated.

摘要： PURPOSE:To increase the dangerous speed and the rigidity of a main spindle at revolution thereof by enlarging the diameter of the main spindle. CONSTITUTION:A main spindle 5 is rotatably attached to a frame body 8 through a radial magnetic bearing 1, which supports the front part of the main spindle 5, and a radial magnetic bearing 2, which supports the midway of the main spindle 5. A built-in motor 3 is incorporated in the rear part of these radial magnetic bearings 1 and 2 in a pair. Accordingly, even if cutting reaction force is applied to the front part of the main spindle 5, the flexure of the main spindle 5 becomes small, and the dangerous speed and the rigidity of the main spindle 5 at revolution thereof is increased.

摘要： PROBLEM TO BE SOLVED: To formulate the arithmetic processing accurately by setting the fixing interval of detector, the moving amount and the number of sets of data string to satisfy a specific formula thereby making clear the cause of error at the time of measurement of the straightness. SOLUTION: Three detectors 4a-4c for measuring the distance to an object to be measured are arranged, at the intervals of La and Lb, on a detector fixing base 3. The fixing base 3 or the object is then moved and the object is measured simultaneously by the detectors 4a-4c for every specified movement P. N sets of data strings, obtained between the starting position and ending position of measurement, are processed to determine the straightness of object with no influence of error in the motion of the fixing base 3 or the object. In this regard, the fixing intervals La, Lb, the specified movement P and the number N of sets of data string are set to satisfy following relationships; La=n1 .P, Lb=n2 .P, La/(N.P)=n4 /n3 , Lb/(N.P)=n5 /n3 , n3 >=N/2, (n1 -n5 are integers where n3 , n4 and n3 , n5 have no common measure).

摘要： PURPOSE: To improve the working properties for measurements and so on in making it free of traveling on a wall surface safely by means of remote control by attaching a wheel to a wheel support leg being rotatable in the longitudinal direction of traveling in time of getting over an obstacle, and making this rotated wheel support leg free of restoration by dint of spring force, while having the wheel built-in with a magnet. CONSTITUTION: A friction winch 51, rotating a drum wheel wrapped with a net or the like spread over a wall surface and making a car body travel along the wall surface, is mounted on a car body 10 mounted with a working apparatus 60. Each four-set of wheels 21 and wheel support legs 24 are installed in both front and rear bodies 12 and 11 of the car body 10, and each magnet 70 is built in each wheel 21. Each wheel support leg 24 is made free of rotation in the longitudinal direction around a turning shaft 27, and when the wheel 21 hit on an obstacle 92 or the like, the wheel support leg 24 turns rearward in the traveling direction, whereby it gets over this obstacle 92, namely, it becomes shiftable freely. After clearing this obstacle 92, the wheel support legs 24 are restored in the original state by action of a return spring 35.
